MOV vs MKV, in short
MOV is Apple's video format: iPhones, Macs, QuickTime and Final Cut save to it. Outside Apple's apps, some Windows programs and upload forms don't take it.
MKV (Matroska) is a flexible container that can hold several audio and subtitle tracks. OBS and other recorders use it because a recording survives a crash, but phones and many editors don't open it.
MOV and MKV can hold the same kinds of video, so the tool first tries copying the video and sound into the new file without re-encoding. That takes seconds and keeps the exact quality. If the codecs don't fit, it re-encodes to H.264 video with AAC sound.
Frequently
Asked Questions
Does converting MOV to MKV lose quality?
Usually not: when the codecs fit, the video is copied as-is. Otherwise it's re-encoded once, which most people won't notice.
Is the sound kept?
Yes. The audio track comes along with the video.
How long does it take?
Seconds for most files, when the video can be copied. Re-encoding takes longer: a few minutes for a few minutes of video.
Is my file uploaded?
No. It's processed in your browser, on your own device, and never leaves it.
