- Keyframe-accurate (may include a few extra frames)
- Best for: Quick clips, large files

Frequently Asked Questions
What is the difference between Fast Mode and Quality Mode?
Fast Mode copies the video stream without re-encoding, making it nearly instant with zero quality loss, but it can only cut at keyframes so the start point may be off by a few frames. Quality Mode re-encodes the video for frame-accurate cuts at the exact timestamps you specify, though it takes longer to process.
Why does Fast Mode not cut at the exact frame I selected?
Video files use keyframes (I-frames) as reference points, and Fast Mode can only cut at these boundaries since it copies the stream without re-encoding. The actual cut may start a few frames before your selected point. For precise frame-accurate trimming, use Quality Mode instead.
Does trimming a video reduce its quality?
In Fast Mode, there is absolutely no quality loss because the original video data is copied directly. In Quality Mode, re-encoding occurs at CRF 18 with AAC 192 kbps audio, which produces near-lossless output that is visually indistinguishable from the original.
What video formats can I trim?
You can trim virtually any video format including MP4, WebM, MKV, AVI, MOV, and more. The tool uses FFmpeg on the server side, which supports all major video codecs and container formats for both input and output.
Is my video uploaded to a server for trimming?
Yes, the video is uploaded to our server for processing with FFmpeg. This enables support for all video formats and both Fast and Quality trimming modes. Your files are automatically deleted within one hour after processing.
