Use keyframes as a visual index
A keyframe export is not the same as saving every decoded frame. It aims to produce a smaller set of images that represent changes in the scene or content, making long recordings faster to scan.
- Create chapter previews for a course.
- Select a cover for a media library.
- Build an index of a meeting or family event.
- Find printable moments in home video.
- Prepare samples for later image analysis.
Export a useful set of frames
Select a time range
Preview the source and restrict processing to the relevant chapter or event.
Choose image processing
Use Original for faithful output, Sharpen for slightly soft preview images, or AI Upscale for low-resolution candidates when the AI component is installed.
Run continuous keyframe export
Monitor progress. Results are stored in a directory named after the video; split very long files into ranges when practical.
Curate and label
Remove transitions, blur, and near-duplicates, then add timestamps or chapter names to the frames you keep.
Choose original, sharpened, or AI output
| Mode | Use it for | Trade-off |
|---|---|---|
| Original | High-resolution sources, evidence, later professional editing | Fast and faithful |
| Sharpen | Slightly soft images used as previews | Can create edges when overused |
| AI Upscale | Low-resolution cover candidates | Slower and introduces inferred detail |
Authenticity: AI upscaling generates plausible detail. Keep the original frame whenever accuracy or evidence matters.
Frequently asked questions
Are more keyframes always better?
No. Too many similar images increase review time. Limit the range and keep only frames that communicate a meaningful change.
Where are exported frames stored?
Continuous export creates a directory named after the source video.
Can I capture only the current frame?
Yes. The editor supports both a single screenshot and continuous keyframe export.
