Extract every frame without losing the timeline.
When you need a frame-by-frame record, keep the source timing and let Chrona map each decoded frame into a continuous archive.

Frame-by-frame extraction is useful for motion studies, animation reference, video quality checks, and datasets where dropping a source frame would change the result. It can create a large archive, so check the estimate before starting.
Chrona's original-rate mode
Original mode follows the video's detected frame timing. Variable-frame-rate files keep their packet timestamps, while the exported frame names remain continuous and one-based.
- Trim first to avoid exporting unwanted sections
- Use the estimate to check frame count and ZIP size
- Keep the original archive manifest with the PNGs
A practical limit
A long or high-frame-rate video can produce more files than a browser tab can comfortably preview. For large jobs, the Chrona CLI uses native FFmpeg and streams entries to disk.
