Comparison
Video file vs screenshots
A dialogue strip needs one frame per line. There are two ways to get those frames, and they differ in how much of the work lands on you.
Route one: you take the screenshots
- Play the clip and pause on the first line.
- Screenshot the player window.
- Repeat for every line.
- Sort the files, then feed them to a stitcher.
The pause is the part that scales badly. Every line adds one pause, one screenshot, and one chance to miss a line.
It has one real advantage: you choose exactly which frames exist. If a line reads better a second later, you take it a second later.
Route two: you hand over the video
QuoteStitch takes the file. Drop in an MP4, MOV or WEBM and it samples the clip, finds the subtitle band, and keeps one frame for each line of dialogue.
You give up frame-level control. Sampling is bounded, so a line that is very short can fall between two samples and be missed.
Route two is faster. Route one is more precise. Neither is right for every clip.
Where route one stops working
On a long clip. Thirty lines means thirty pauses, and the error rate climbs with the count. The line you miss is usually the one you wanted.
Where route two stops working
When the subtitles are not in the picture. QuoteStitch reads pixels, so a separate .srt or .vtt file is invisible to it. Burned-in subtitles only.
It also cannot reach a stream playing in another tab. There is no network access: you supply the file, and you need the right to use it.
Fixing what either route missed
Both routes end in the same editor. The band is a measurement, not a setting: two sliders move its top edge and its height, and a button re-measures it.
So a missed line is not a lost line. Move the band, re-detect, and export again.
Which route to take
- A short clip, or you need exact frames — take the screenshots yourself.
- A long clip, or you have the file — hand over the video.
- Subtitles in a separate file — neither route applies. You want a subtitle file tool.
Frequently asked
Is it faster to screenshot or to use the video file?
The video file removes the pause-and-capture loop entirely. On a long clip that loop is the whole job, so the gap grows with the number of lines.
Can I get an exact frame from a video?
Sampling is bounded, so the frame you get is the nearest sample rather than a frame you named. For an exact frame, a screenshot you take yourself is the reliable route.
What video formats are accepted?
MP4, MOV and WEBM — whatever your own browser can play. Nothing is uploaded, so only your browser needs to support the format.
Does it work with subtitles from a streaming service?
It reads burned-in subtitles from a file you supply. It cannot capture a protected stream playing in another tab, and it does not bypass DRM.
Do I lose quality by using the video route?
The frames come from the file at its own resolution, and the export is a PNG at 1x or 2x. The long image keeps the source detail.
