Small things worth checking
- Use frame-accurate trimming to cut exactly where you want. No need to guess or pad extra time.
- For sharing in chat apps, export as GIF or animated WebP to get a file that auto-plays and loops.
- If the recording is long, consider adjusting playback speed to compress time. FastEdit supports speed changes.
- Frame deduplication is especially useful for screen recordings, where many consecutive frames are identical (e.g., during pauses).
- Export to MP4 with H.264 for the smallest video file size with maximum compatibility.
