Removing subtitles that change position or move

Updated October 26, 2026 · Peelframe

Subtitles that always sit in the same spot at the bottom are easy. Real videos, though, often move them from scene to scene, put big text in the middle of the frame, or animate the letters in. Here is the right setting for each case.

The principle: the box stays put, the text is found in every frame

Remove subtitles automatically and the default area setting (Subtitle text · when visible) look for text afresh in every frame. Within the range you set, they follow subtitles that move or change position. Whole fixed overlay · selected time, by contrast, erases the box where it is and does not follow movement. Use the default for moving text.

Case 1. Subtitles that switch between bottom and top

Some videos keep subtitles at the bottom but move them up when other text sits there. If there is little other text in the frame, the simplest choice is auto removal with the Search area set to Whole frame.

If there is text that must stay, such as a sign or a product label, use Select an area with one box in the Top area and one in the Bottom area. With both on the default setting, each erases only when a subtitle shows in its place.

Case 2. Big text in the middle

Emphasis captions and lecture titles often sit in the middle. Use a Middle area box or the Middle third search area. The bigger the text, the more the AI has to draw, so check with Test current frame before processing everything.

Case 3. Text that animates in

For text that slides in from the side or grows into view, draw one box over the whole path it travels and keep the default setting. Parts of the box without text keep the original picture.

Shaking text or text that is still faint during its entrance effect can be missed. Raise Detection sensitivity in Detection details to High · catch faint text; if patterns that are not subtitles start being erased, go back to Standard.

Case 4. Color-fill caption effects

Captions whose color fills in with the speech or music keep the same letter shapes, so the default setting erases them. Just make sure the thick outline around the letters is inside the box.

Case 5. Text that flashes by

Text that shows for only a few frames can be missed. When processing ends, Leftover subtitle check shows thumbnails of frames that may still have text. Click one to jump there, paint the remaining letters, set a start and end time and press Re-restore selected range: only that range is redone and the rest of the result stays as it is. Auto-select leftover text can mark the spots for you.

When four boxes are not enough

You can draw up to four boxes. For videos whose subtitles move very often, use auto removal instead, and if the text that must stay is only on one side of the frame, narrow the search area to the third where the subtitles appear. Failing that, split the video by scene, process the parts separately and join them in an editor.
