About converting MKV to MP4
MKV is a flexible container that can hold multiple audio, video, and subtitle tracks in one file. MP4 is the most widely supported video format, playable on virtually every device and platform. Converting from MKV to MP4 swaps one for the other without changing the underlying content.
Re-encoding video is lossy, so we use quality-preserving defaults — you can still tune the resolution, quality, and frame rate before you start.
