Frequently asked questions
Is my video uploaded to a server?
No. Analysis, preview and processing use the video in your browser. A report and optional sample are sent only after you explicitly choose and authorize them.
Which videos are supported?
MP4, MOV or WebM, up to 40 MB and 4 million pixels per frame. One video track. Support depends on the file’s codecs and your browser. Protected files are rejected. Check the result before use.
Is the trim exact?
No. We include the complete groups of frames needed to play the clip. The start may move back to the previous keyframe and the end may move forward to the next one. The result shows the actual interval, which may include content outside your request. Check before sharing.
Is audio kept?
Compatible audio tracks are copied with the same time offset as the video. Boundaries follow whole audio packets and may add milliseconds. Some tracks need a brief decoder warm-up. Tracks with no content in the clip are omitted. If a codec cannot be copied, the operation is rejected.
What information is copied?
We copy the video and compatible audio tracks. Subtitles, chapters and descriptive file tags are not copied. Images and technical data remain present; this is not an anonymization tool.
Is there a duration limit?
There is no fixed limit in minutes. We accept videos up to 40 MB within the listed format and resolution limits. Processing has a 90-second time limit and can be cancelled; long or complex videos may exceed your device’s resources.
