Questions and answers
Why is it often so fast?
MKV files usually contain H.264 or H.265 video, which fits into MP4 as well. Cutwisp then only changes the container and doesn't re-encode anything.
What happens to subtitles and several audio tracks?
Cutwisp keeps the main video track and the main audio track. Subtitles and extra audio tracks are left out.
Is my file uploaded?
No. Cutwisp processes the file inside your browser. It is never sent to a server.
Does it cost anything? Is there a watermark?
Cutwisp is free, and it doesn't add a watermark.
