- What is the difference between keyframe and frame-accurate cutting?
- Keyframe cutting (default) is near-instant because it copies data without re-encoding, but may start a few frames before your chosen timestamp. Frame-accurate mode re-encodes the clip so it starts and ends exactly where you specified.
- Can I trim a video without re-encoding?
- Yes, leave Frame-Accurate Cut off. The tool uses stream copy to cut at the nearest keyframe — this is extremely fast and preserves the original quality.
- What output formats are supported?
- You can save the trimmed clip as MP4, MKV, or MOV. All three formats are widely supported across devices and video players.
