Frequently asked questions
Which format plays everywhere?
MP4 with H.264 video and AAC audio works on virtually every phone, computer, TV and website.
When should I use WebM?
WebM (VP8 + Vorbis) is open and great for websites. It doesn't play in some older Apple software.
Why is converting MKV to MP4 so fast sometimes?
If the video is already H.264, the tool can copy the streams into MP4 without re-encoding.
