FAQ
What video formats can I merge?
You can merge videos in any format your browser supports, including MP4, WebM, and MOV. All clips will be re-encoded into a single consistent output format.
Do the videos need to have the same resolution?
No. Each video is rendered to a common canvas size (the largest video's dimensions). However, for best results, use videos with similar aspect ratios.
How does the merging work technically?
Videos are played sequentially. Each frame is drawn to a shared canvas, and the canvas stream is recorded into a single output video using the MediaRecorder API. No server-side processing is involved.
