Split video into parts
Cut an MP4 or WebM video into up to ten parts by number of parts or length, for example to fit a messaging app’s time limit.

Split re-encodes; audio extraction creates PCM WAV; tags are removed. Compression is a bounded attempt, never a guarantee. Compression preserves compatible AAC/MP3 audio packets; other audio requires an available AAC encoder. A final remainder shorter than 0.1 seconds is included in the preceding clip, which can be longer than the chosen interval. The full timeline is retained; maximum ten clips.

Split video into parts
- Prepare the input
Choose a supported video and split it by clip length or by the number of parts you want. Check the interval shown and the planned parts; the profile allows at most ten clips. Splitting re-encodes the video and depends on native codec support.
- Try the worked example
A nine-second source split into three-second intervals gives the ranges 0–3, 3–6 and 6–9 seconds. Check each saved clip and the full timeline in order. A remainder below 0.1 seconds is joined to the preceding clip instead of being dropped.
- Check and save
Save all the clips you want and check their beginnings and ends against the source. The final clip can be longer than the interval you asked for when it absorbs a tiny tail. Keep the original. Splitting is not a guarantee of lossless packet copying.
Questions
Why is the last clip slightly longer?
A final remainder shorter than 0.1 seconds is added to the clip before it, so the full timeline is preserved. It is not silently discarded or forced into a tiny clip that would be invalid.
Why is my part count rejected?
The profile allows at most ten clips and valid, non-empty intervals. Increase the interval length or reduce the number of parts you ask for. There is no unlimited batch or export streamed to disk.
Does splitting preserve original compressed packets?
No. This workflow re-encodes the ranges you ask for. Check the actual clips, the codec availability, the sound and the dimensions. Keeping the source timeline doesn't promise identical encoded bytes or metadata.
