Frequently Asked Questions
What is the difference between fast mode and precise mode? +
Fast mode copies the video data without re-encoding, so it finishes in seconds. However, it can only cut at keyframes, so the start/end times may be slightly off. Precise mode re-encodes the video for frame-accurate cuts, but takes longer.
What video formats are supported? +
Most common formats work, including MP4, WebM, MOV, AVI, and MKV. The output format matches your input file. If your browser can play the video, the trimmer can process it.
Why does fast mode cut at slightly wrong times? +
Videos are split into groups of frames starting with a keyframe. Fast mode can only cut at these keyframe boundaries. If you need exact timestamps, switch to precise mode which re-encodes the video for frame-accurate trimming.
Is there a file size limit? +
There is no fixed limit, but very large files (over ~2 GB) may cause your browser to run out of memory. For best results, keep files under 500 MB. Processing time depends on your device speed.
How do I enter times in MM:SS format? +
Type the minutes and seconds separated by a colon. For example, 1:30 means 1 minute and 30 seconds. You can also just enter plain seconds, like 90 for the same time.
