Trim Video lets you choose the exact section of a video you want to keep. Set start and end points from the preview, then use Fast cut for speed and no quality loss or Exact cut when tighter timing is more important.
Common use cases
Create short excerpts
Keep only a useful section for sharing, review or social posting.
Prepare clips before merging
Trim source videos to the exact ranges needed before joining them together.
How it works
1
You choose the start and end time for the section to keep.
2
Fast trimming can preserve encoded streams when supported, while exact trimming may require re-encoding around the chosen boundaries.
3
A new video containing only the selected range is created.
Privacy & file handling
Video trimming stays local
The supported trim workflow processes the source clip in the browser rather than requiring it to be uploaded to Zavilo.
Limitations and important notes
- Lossless trimming can be limited by keyframe positions and may start slightly earlier than an exact requested frame.
- Exact frame-level trimming can require re-encoding and therefore more time.
- Cutting a segment does not automatically normalize audio, stabilize video or change resolution.
Fast trim vs exact trim
| Feature | Advantage | Tradeoff |
|---|---|---|
| Fast / stream-oriented trim | Quicker and can avoid full re-encoding | Boundaries may follow keyframes |
| Exact trim | More precise start and end timing | Usually slower and may re-encode video |
How to use Trim Video
- 1
Choose an MP4, WebM or MOV video.
- 2
Move through the video and set the start and end points.
- 3
Preview the selected section and fine-tune the time sliders if needed.
- 4
Choose Fast cut for a quick no-quality-loss trim or Exact cut for more precise timing.
- 5
Trim the video and download the selected clip.
Tips for better results
- Fast cut copies the original audio and video streams, so it is quick and does not reduce quality.
- Because Fast cut follows existing keyframes, the actual starting frame can be slightly earlier or later than the selected time.
- Use Exact cut when a precise start or end point matters more than processing speed.
Frequently asked questions
Does trimming reduce video quality?
Fast cut does not re-encode the video, so quality is preserved. Exact cut re-encodes the selected section to improve timing precision.
Why can Fast cut start a little away from the selected time?
Many video formats can begin a copied segment only at certain keyframes. Exact cut is designed for tighter timing.
Which video formats are supported?
The tool accepts MP4, WebM and MOV files. Playback and processing can still depend on the codecs used inside the file.
