About this tool
Trimming a video means keeping only the useful segment and dropping everything before and after it. You set a start and end time, preview the cut, then export a shorter clip - without opening a full timeline editor for a one-minute job. That is the usual need for social highlights, removing silence at the start of a recording, or cutting a demo down to the part people should actually watch. Trimming reduces duration, which usually shrinks file size as a side effect; it is not the same as compression, which re-encodes bitrate while keeping the whole timeline. Use the Video Compressor when the clip is already the right length but still too heavy to upload.
Cut a clip down for social media
Trim before you compress - there is no point spending bitrate on frames you are removing.

Best clip lengths for social media
Short clips perform best: about 15 to 30 seconds for TikTok, Reels and Shorts, up to around 60 seconds for most feed posts, and under 2 minutes for X. Put the most interesting moment in the first two seconds, because that is when people decide to keep watching.
Trim the silence and setup at the start and end of a recording before you share it - it is the simplest edit that makes a video feel more professional.
Key features
- Removes unwanted footage quickly without full editor.
- Useful for social clips, demos, and highlights.
- Reduces file size by cutting duration directly.
- Simple workflow for fast turnaround edits.
Common uses
- Extracting short highlights from long recordings.
- Removing dead time at beginning/end of clips.
- Preparing platform-specific short-form content.
- Cutting tutorial sections for focused sharing.
Tips for better results
- Trim first, then compress for best quality/size outcome.
- Use frame-level preview for precise cut boundaries.
- Keep a small safety margin before important speech/action.
- Retain original file for future recuts.
Mistakes to avoid
- Cutting too tightly and clipping key context.
- Overwriting original without backup.
- Assuming one trim output fits all platform length limits.
- Skipping preview and exporting wrong segment.

Frequently asked questions
Run the trim operation once per clip you need - each trim produces one output clip covering the start/end range you specify.
No - trimming just cuts out the portion outside your selected range; the remaining footage keeps its original quality.
Trimming typically supports precise timestamp selection (down to fractions of a second in many cases), so you can cut exactly where you want rather than only at rough intervals.
Clips of up to 10 minutes can be trimmed here. Trimming copies the original video data rather than re-encoding it, so longer clips do not lose quality - they simply take a little longer to load.
Short clips perform best: under 60 seconds for Reels, Shorts and TikTok, and under about 2 minutes 20 seconds for a standard X (Twitter) post. Trim to the strongest moment and cut the slow start.
Videos can only be cut cleanly at keyframes when the data is copied without re-encoding. The start snaps to the nearest keyframe, usually within a second or two of the time you picked.
