You do not need to understand how any of it works internally. If you follow one workflow from Part 3 from top to bottom, you will have a finished video at the end.

1.2 What you need

A Windows computer with the app installed and signed in.
The video file you want to clean, somewhere easy to find.
Optional but helpful: a graphics card. Turn on Use GPU in the bottom toolbar when it is available and the job will finish sooner.

A tip before you begin: work on a copy of the video the first time until you are happy with the result.

Part 2 — The Window and Its Controls

2.1 Sign-in screen

Item	What it does
Proxy settings	Opens proxy options if your network needs one to reach the server.
Log in	Signs you in and opens the main window.

2.2 Left sidebar: files and advanced control

Button	What it does	How to use it
Choose device	Picks the processing device (for example processor-only or a graphics card).	Click it and pick the recommended entry. If you are unsure, leave it alone.
Choose folder	Loads every video in a folder into the list.	Click it, pick the folder, and all videos appear in the list.
Advanced control panel	Opens the section with the fine-tuning controls below.	Click to expand it; it stays open.
Process the list automatically	When ticked, the settings you made for the first video are copied to every other video.	Tick it for a folder of similar videos. Leave it off when each video needs its own settings.
Time (s) + Annotations	Jump to a moment and edit the marks at that moment.	Type a time, press the Annotations button, then add or adjust the mark for that moment.
Range expansion (px) — Add width / Add height	Makes the covered area slightly wider or taller than the watermark.	If a thin slice of the watermark stays visible at the edges, raise these a little (for example 12 and 12) and run again.
Time compensation — Earlier / Later, Earlier: / s delay:, Apply time compensation	Shifts how early the covered area starts and how long it lingers.	If the watermark appears a moment before your coverage starts, put a value in Earlier and click Apply time compensation. Use Later for the opposite problem.
Change duration	Changes how long a mark stays active.	Select a mark in the list, click Change duration, enter the new length.
Tutorial	Opens the built-in help.	Use it as a reminder of the basic order of operations.
Export annotations / Import annotations	Saves your marks to a file, or loads marks you saved earlier.	After a long manual marking session, click Export annotations so you never have to redo it. Use Import annotations on a second video with the same watermark.

2.3 Bottom toolbar: playback and running a job

Button	What it does	How to use it
Open video	Opens a single video file.	Use it when you want to work on one video rather than a whole folder.
Play	Starts and pauses playback.	Pause on a frame where the watermark is clear and fully visible. That frame is what you will box.
Speed box (0.1x … 8.0x)	Sets playback speed.	Use 0.1x or 0.3x when you are hunting for the exact moment a watermark appears or disappears.
Add annotation	Turns on drawing mode so you can mark an area yourself on the current frame.	Click it, drag a box over the watermark. Use it to fix a moment the app missed.
Start single process	Runs the job on the video that is currently loaded.	This is the button you press when everything is configured.
Start batch process	Runs the job on every video in the list on the left.	Press it after you have configured the videos (see Workflows G and H).
Use GPU	Asks the graphics card to do the heavy work.	Tick it whenever it is available; jobs finish sooner.
Time —	Shows how long the current job has been running, and the total time when it finishes.	Nothing to press; just watch it.
Fullscreen playback	Opens the video full screen for easier visual checking.	Press it to inspect a frame closely, then Exit fullscreen to come back.

2.4 The seven tabs on the right

Tab	What it is for
Processing & parameters	Choose how the watermark will be painted out. You must pick one here before any removal can run.
Moving watermark	The main tab for watermarks that move. All the tracking buttons live here.
Static/jump	Watermarks that never move, plus text clean-up tools.
Semi-auto batch	Prepare several videos one at a time, then run them all together.
Auto batch processing	Prepare one video automatically and apply the same plan to every video.
Hard subtitle extraction	Pull burned-in subtitles out as text (a separate, standalone tool).
Export settings	Where the finished file goes, what it is called, and its quality and format.

A good habit: start on Processing & parameters, then do your tracking work, then check Export settings, then run.

Part 3 — The Workflows, Step by Step

3.1 Decide what kind of watermark you have

Do this first — it decides which button you press.

Click Open video (or load a folder with Choose folder and double-click a video).
Press Play, then set the speed box to 0.1x or 0.3x.
Watch the watermark at three or four different moments in the video, then pause.

What you see	What it is	Go to
It never moves	Static watermark	Workflow I, on the Static/jump tab
It slides around, always the same size	Moving watermark	Workflow A
It slides around and gets bigger or smaller	Moving and resizing	Workflow B
It disappears, then comes back somewhere else	Jumping watermark	Workflow C
It comes back somewhere else and keeps sliding	Jump plus movement	Workflow C
There is more than one watermark, or you cannot tell	Mixed or unknown	Workflow E (fully automatic)

The single most useful habit: pause on the clearest frame of the watermark. Everything you box or pick is based on that frame.

3.2 Workflow A — A moving watermark, single video (recommended first try)

This is the standard route and the one to learn first.

Step 1 — Load the video. Click Choose folder and double-click the video, or click Open video and pick the file.

Step 2 — Find a clear frame. Press Play, drop the speed to 0.1x if you need to, and pause where the whole watermark is sharp and fully on screen.

Step 3 — Choose how it will be removed. Go to the Processing & parameters tab and click a method in the list (see section 4.3 for which one to pick). Nothing can run until a method is selected.

Step 4 — Box the watermark. Go to the Moving watermark tab and click Fixed-size path. A drawing guide appears: drag a box around the watermark on the picture and confirm. Make the box a couple of pixels larger than the watermark on every side — slightly too big is much better than slightly too small.

Step 5 — Choose how often it is checked. A small window appears with Check interval mode:

Choice	When to use it
Per second	Default choice. Good for watermarks that drift slowly.
Per frame	Use when the watermark moves quickly.
Check every frame	The most thorough and the slowest. Use it for stubborn or flickering watermarks.

Set the interval value if you want something other than the default, then confirm.

Step 6 — Let it scan, then review. The app goes through the video and produces a list of moments and areas under Text tracking annotations. Check them:

Press Play and watch the marks appear over the picture.
Hide path turns the path lines off and on so you can see the real picture underneath.
If a moment is missing, park the playhead there, click Add annotation, and box the watermark yourself.
Click Edit annotation to reshape a mark, or Delete annotation to remove one that is wrong.
Still seeing a sliver of the watermark at the edges? Raise Range expansion (px) — Add width and Add height — and run again.
Coverage starting a touch late or stopping a touch early? Use Time compensation and click Apply time compensation. Use Change duration to lengthen or shorten one particular mark.

Step 7 — Confirm the removal. When the app asks whether to start removing the watermark now, say yes.

Step 8 — Set the output. Open the Export settings tab and choose the folder, the file name style, and the quality (see Workflow J).

Step 9 — Run it. Tick Use GPU in the bottom toolbar if it is available, then press Start single process. Watch Time —, and open the finished file from your chosen folder when it is done.

3.3 Workflow B — A watermark that grows and shrinks

Use this when the watermark changes size as it moves (it drifts across the picture and gets larger near the camera, or shrinks into the distance).

Load the video and pause on a clear frame, exactly as in Workflow A.
On the Processing & parameters tab, pick your removal method.
On the Moving watermark tab, click Watermarks that grow and shrink. The app reads the text it can see on the current frame and shows you a list, each entry with its position.
Click the entry that is your watermark and confirm. If the watermark is not in the list, move to a sharper frame and try again.
Choose the Check interval mode and value, as in Workflow A.
Review the marks the same way — Add annotation, Edit annotation, Delete annotation, Hide path, Range expansion (px), Time compensation.
Confirm removal, set Export settings, tick Use GPU, press Start single process.

Tip: because the size changes, leave a little extra room with Add width / Add height rather than making the corners exactly tight.

3.4 Workflow C — A watermark that jumps around

Use this when the watermark sits still for a while, vanishes, and reappears somewhere else.

Load the video, pause on a clear frame, and pick your method on the Processing & parameters tab.
On the Moving watermark tab:
- If it only jumps and never slides: click Jump + moving fixed-size path and box the watermark.
- If it both jumps and slides: same button — box the watermark and let it work.
Choose Check interval mode. For jumping watermarks Per second with a smaller value, or Per frame, catches the reappearances more reliably.
Review the marks. Jumping watermarks are the most likely to need Add annotation for a position the app did not see; add those moments by hand.
If the watermark also changes position slightly within one appearance, raise Add width / Add height a little.
Confirm removal, set Export settings, tick Use GPU, press Start single process.

If the watermark is completely still but simply comes and goes, you do not need this tab at all — use Static/jump and see Workflow I.

3.5 Workflow D — Several watermarks at once

Use this when two or more watermarks are on screen at the same time, whether they carry the same text or different text.

Load the video, pause on a clear frame, pick your method on Processing & parameters.
On the Moving watermark tab, click Multi-watermark motion path.
Box the first watermark. Then, when the app shows you the text it has found, select every watermark you want removed and confirm.
Choose the Check interval mode and value.
Review the annotation list once per watermark — each one is tracked on its own, so check that each has coverage across the whole video.
Confirm removal, set Export settings, tick Use GPU, press Start single process.

If the watermarks share the same picture but differ in size, or you would rather not box each one, jump to Workflow E instead.

Multi-select character path is the variant to use when the watermark contains several separate pieces of text (for example a name plus a number): click it, box the area, tick each piece you want tracked, and confirm. Each piece is then followed on its own.

3.6 Workflow E — Fully automatic multi-watermark (no boxing)

Use this when you do not want to box anything, when there are several watermarks, or when you are not sure what kind of watermark you are dealing with.

Load the video and pause anywhere.
Pick your removal method on the Processing & parameters tab.
On the Moving watermark tab, click ★ Full-auto multi-watermark path (jump/moving decided automatically).
The Automatic detection settings window opens. The defaults suit most videos, so you can simply press OK — but here is what each part does if you want to tune it (full details in section 4.11):
- Watermark source — either use the watermarks you have ticked in your Watermark library, or let the app find watermarks that keep appearing in the video on its own (no boxing needed).
- Check interval mode and Interval value — how closely the video is looked at. Smaller value = more thorough and slower.
- Detection precision, Sensitivity, Continuity requirement, Same-watermark gap, Decision distance, Disappear time, Lead compensation, Delay compensation, Minimum occurrences — fine tuning. Leave them alone on the first run.
- Double-check the uncertain spots — leave Enable ticked. It noticeably reduces the moments that get missed. Max frames to re-check is a safety limit for long videos. Keep Double-check the places where no watermark was seen ticked as well, so faint moments are not written off too early.
- Specify the method — leave it on decide automatically. If a watermark keeps moving and some of it is still visible afterwards, choose Treat all as continuously moving.
- Do-not-disturb mode — Do not ask again; remove the watermark right after detection runs the whole job without stopping to ask. Very convenient for batches, but check one video first.
- Watermark size — Margin — the safety margin around the watermark. If any part stays visible, raise this first.
- Compensation method — leave Recommended for moving watermarks selected unless you are working with a still watermark.
The settings are remembered, so you only have to set them once.
Press OK. The app finds the watermarks, works out how each one behaves, and (unless you turned on do-not-disturb) asks you to confirm.
Press the confirmation to start. Progress shows in the status area, and you can press Cancel to stop.
Collect the finished file from your export folder.

3.7 Workflow F — Save a watermark and reuse it (Watermark library)

Do this when the same watermark appears in many videos. You box it once, and from then on every mode — including the fully automatic one — can use it.

Load any video that contains the watermark and pause on a clear frame.
On the Moving watermark tab, click Box and add to library.
Drag a box over the whole watermark on the picture and confirm. The app measures it and stores it.
Click Watermark library to open the library window and check the entry:
- Watermark type — text only, or text with a graphic such as an icon or avatar.
- Watermark name — a label for your own reference.
- Watermark text — the words on the watermark.
- Match mode, Detection precision, Coverage — how strictly the app looks for it.
- Horizontal scale, Vertical scale, Left / Up / Right / Down, Size, Converted size — the shape and position to look for.
- Automatically fit the real watermark size in each video — keep this on; it adapts to videos of different sizes. Scale to the picture size and Use the current video size help when your videos come in several resolutions.
- Enable — tick it so the entry takes part in automatic detection.
- Re-measure the text size from the current frame and Try it on the current frame — use these to check an entry without running the whole video.
Repeat for any other watermarks you want on file.
Housekeeping:
- Import watermark library loads a set you saved before; Export watermark library saves the current set to a file you can keep or move to another computer.
- Deleting an entry asks you to confirm first.

Once an entry is ticked, choose Using the watermarks ticked in the library the next time you run the fully automatic mode and it will look only for your watermarks.

3.8 Workflow G — Batch: many videos, same watermark

Use this when you have a folder of videos and each one needs its own quick setup.

Click Choose folder and load the folder. All the videos appear in the list on the left.
Go to the Semi-auto batch tab. The Task video list shows the same videos.
Select a video in the list. The panel on the right shows Current video configuration.
Under Removal plan (choose one), pick one plan for that video:
- Configure moving watermark… — for moving watermarks. It walks you through three short steps: choose the text to follow, define the tracking box, then set the scan interval. The result is saved for that video.
- Configure static/jump… — for watermarks that sit in fixed places.
Under Additional regions (can be stacked), use Add a manual static region… if the video also has a fixed area that needs covering. You can stack more than one, and each can cover the whole clip or only a time range.
Repeat steps 3 to 5 for the other videos. The list shows each video’s status as you go: Configured, or Waiting for a task… if it is not set up yet.
Made a mistake? Clear this video’s configuration resets the selected video.
Do not want to box anything at all? The panel reminds you: use the fully automatic multi-watermark on the Auto batch tab — that is Workflow H.
When everything is prepared, press ✅ Start all configured tasks. Progress is shown with the status text and you can press Cancel to stop.

3.9 Workflow H — Batch: fully automatic across a whole folder

Use this when every video in the folder should be cleaned the same way with no boxing.

Load your folder with Choose folder.
Go to the Auto batch processing tab. Its Task video list shares the same tasks as the Semi-auto batch tab, so anything you prepared there is already here.
Select one video and click Configure auto multi-watermark (only the selected video)… — the same automatic detection settings window from Workflow E opens. Set it up and confirm.
Click ★ Apply to all videos to give every video in the list the same plan. (This asks you for the settings again, then applies them everywhere.)
Need a clean slate? Clear all configurations resets every video to the not-configured state.
Press 🚀 Start auto batch processing to run all configured videos one after another.
Leave the computer alone while it works, and collect the results from your export folder.

Before you start a long batch: run one video on its own first with Workflow E and look at the result. Then launch the batch.

3.10 Workflow I — Static watermarks and text clean-up

The Static/jump tab handles watermarks that stay in one place, and the text tools.

Button	What it does	How to use it
Add static region	Adds an area that is covered for the whole clip or for the time range you choose.	Click it and drag a box over the watermark; set how long it should apply if it is not the whole video.
Smart jump detection	Finds a watermark that vanishes and comes back in a new position and covers each position.	Click it with a clear frame on screen and follow the prompt.
Fixed-size jump detection	The same idea, for a watermark you box yourself so the exact size is known.	Box the watermark when asked; the size is used as the template.
Subtitle removal detection	Looks for subtitle-style text and covers it.	Use only when you really mean to remove subtitles; check the result before running the whole video.
Remove all text (use with care)	Takes out every piece of text it can find on screen.	Only for footage where no text is wanted at all. It cannot tell a watermark from a shop sign or an on-screen title, so review carefully.
Delete static region	Removes the selected region from the list.	Select the region in the list first, then click.
Clear jump detection	Clears the jump-detection results.	Use it to start the jump detection over from scratch.
Change duration	Changes how long the selected region applies.	Select the region, click it, enter the new length.
Non-subtitle cleanup	A follow-up tidy-up after subtitle detection: off, automatic, manual, or open its settings.	Leave it off unless you used subtitle detection and want the leftover non-subtitle marks cleaned too.
The list below the buttons	Every region you have added, in order.	Click a row to select it before editing or deleting.

3.11 Workflow J — Export your finished video

Everything about the output file lives on the Export settings tab.

Where it goes — under Save location and file name, choose:
- Same folder as the source video, or
- Use a custom folder, then pick the folder with Choose a folder… / Browse… and check the path shown in Specified folder:.
What it is called — use File name: to keep the original name, or to add the processing method so you can tell cleaned files apart at a glance.
Quality & format — set Quality mode, Video format, and, if you want, the extra sliders (Clarity, Bit rate, Output speed, Audio, Audio quality).
GPU acceleration — tick Let the GPU help with video reading as well (faster) when your computer can do it. Check whether the GPU is usable runs a quick test and tells you whether this computer can export with the GPU. The status line at the bottom of the group spells out what your current settings mean, for example that the picture is kept as is for the fastest export.
Go back and press Start single process or Start batch process on the bottom toolbar to actually produce the file.

4.11 Automatic detection settings window

Opened by ★ Full-auto multi-watermark path and by Configure auto multi-watermark…. The defaults work for most videos.

Setting	What it means in plain terms
Watermark source: Using the watermarks ticked in the library	Look only for watermarks you have saved and ticked. The safest option.
Watermark source: Automatically find watermarks that appear repeatedly in the video	Find watermarks by itself. No boxing needed, but it may also pick up other text that keeps appearing.
Check interval mode / Interval value	How closely the video is examined. Smaller values are more thorough and slower.
Detection precision	How strictly a match is accepted. Lower values are more willing to match.
Sensitivity	How readily movement is noticed. Lower it if a moving watermark is being lost.
Continuity requirement	How consistently the watermark must be present to count.
Same-watermark gap	The longest gap allowed between two appearances of the same watermark.
Decision distance	The distance at which a change of position counts as a jump.
Disappear time (s)	How long the watermark must be absent before it is treated as gone.
Lead compensation (s) / Delay compensation (s)	Start coverage a little earlier and let it linger a little longer.
Minimum occurrences	How many times the watermark must appear before it is accepted. Raise it to ignore one-off text.
Double-check the uncertain spots: Enable	Recommended. Noticeably reduces missed moments.
Max frames to re-check	A limit so very long videos still finish in reasonable time.
Double-check the places where no watermark was seen	Recommended. Avoids writing a faint moment off too early.
Specify the method	Leave on Decide automatically (default). Choose Treat all as continuously moving if parts of a moving watermark stay visible; Treat all as jump + moving is the safe fallback when unsure.
Do-not-disturb mode: Do not ask again	Runs straight through without confirmation. Convenient for batches; test one video first.
Appearance ratio at least	How often the watermark must appear for it to count as a watermark.
Watermark size: Margin	The safety margin around the watermark. Raise this first if any part stays visible.
Use the largest measured size / Auto tiering	Use the largest size measured, or handle large and small watermarks in the same video separately.
Compensation method: Recommended for moving watermarks / Stay in place	How the covered area is positioned as the watermark moves. Keep the recommended option for moving watermarks.

The window remembers your settings and restores them next time, and the bottom of the window explains the colours and hints shown in it.

Part 5 — If Something Goes Wrong

5.1 The watermark is still partly visible

Raise the safety margin: Range expansion (px) on the left, Add width and Add height. Try a small increase first.
In the automatic mode, raise Watermark size: Margin instead.
Re-box the watermark slightly larger, a couple of pixels beyond every edge.
If a moving watermark is only partly covered, set Specify the method to Treat all as continuously moving.

5.2 The first or last moments are not covered

Use Time compensation on the left: put a value in Earlier and click Apply time compensation.
In the automatic mode, raise Lead compensation and Delay compensation.
For one particular moment, select its mark and use Change duration.

5.3 Some moments in the middle are missed

Keep Double-check the uncertain spots and Double-check the places where no watermark was seen enabled.
Change Check interval mode to Per frame or Check every frame.
Lower Detection precision a little so the app is more willing to accept a match.
Add the missed moment by hand: park the playhead there, click Add annotation, and box the watermark.

5.4 Subtitles or on-screen text were treated as watermarks

Switch the Watermark source to Using the watermarks ticked in the library, and save your watermark there first with Box and add to library.
Raise Minimum occurrences and Continuity requirement.
Raise Detection precision so only exact matches count.
Turn off the do-not-disturb option for the next run so you can check the detection before it removes anything.

5.5 A fast-moving watermark gets lost

Change the Check interval mode to Per frame and reduce the interval value.
Lower Sensitivity so small movements are noticed more readily.
On the left, switch on the automatic processing of the list only after a single video works well.

5.6 Nothing was found to remove

Move to a frame where the watermark is sharp and fully visible — a blurry or half-covered frame is the most common cause.
Re-box it, and make the box a little larger than the watermark.
If the watermark is small on screen, lower Detection precision on the Moving watermark tab.
Try the fully automatic mode instead, which does not rely on a single frame.

5.7 The job takes much too long

Tick Use GPU in the bottom toolbar.
Choose a faster method on the Processing & parameters tab, such as AI fast seamless repair or Delogo.
Use Per second instead of Check every frame, and raise the interval value.
Lower Max frames to re-check in the automatic detections settings.
Set Quality mode and Output speed on the Export settings tab to a faster option.

5.8 A warning says something is not configured

“Choose a processing method” — go to the Processing & parameters tab and click one method in the list.
“Load a video first” — use Choose folder or Open video before configuring.
“Select an entry first” — click a row in the watermark library list.
“The task list is empty” — load your folder with Choose folder on the left.
“This feature is not available” — the message tells you which alternative, such as the Semi-auto batch tab, to use instead.

Part 6 — Cheat Sheet

The one-page version of everything above

Load — Choose folder or Open video.
Find a clear frame — Play, slow to 0.1x, pause where the watermark is crisp.
Pick a method — Processing & parameters tab. Nothing runs without it.
Choose your route — Moving watermark tab:
- steady size → Fixed-size path
- changes size → Watermarks that grow and shrink
- jumps around → Jump + moving fixed-size path
- several at once → Multi-watermark motion path
- no idea / no boxing → ★ Full-auto multi-watermark path
- same watermark everywhere → Box and add to library first
Box it loose — a couple of pixels wider than the watermark on every side.
Set the check interval — Per second for slow movement, Per frame for fast, Check every frame when you want maximum thoroughness.
Review the marks — Add annotation for anything missing, Edit annotation / Delete annotation to fix, Hide path to see the real picture.
Tighten the fit — Add width / Add height if edges remain, Time compensation if the start or end is missed.
Confirm and run — tick Use GPU, press Start single process.
Export — Export settings tab for the folder, the file name and the quality.

For a folder of videos: prepare each one on Semi-auto batch and press ✅ Start all configured tasks, or set one up on Auto batch processing, press ★ Apply to all videos, then 🚀 Start auto batch processing.

Always test one video before a long batch.
