MKV vs MP4
Matroska (MKV) is a flexible container popular for recordings and archives, but many TVs, phones and editors only accept MP4.
Copy instead of re-encode
If the MKV holds H.264, HEVC or AAC streams, they move into the MP4 untouched — fast and with zero quality loss.
FAQ
What about subtitles in my MKV?
Subtitle tracks aren’t carried over to MP4; video and audio are.
Multiple audio tracks?
The primary video and audio tracks are converted.
What can you do with a video converter?
Creators convert iPhone MOV clips and screen-recorded WebM files to MP4 before posting to Instagram, TikTok or YouTube; podcasters and students pull MP3 audio from interviews and lectures; developers and support teams turn short screen captures into GIFs for docs and chats; editors rewrap MKV recordings into MP4 so their NLE accepts them; and motion designers convert Animdock WebM exports into whatever format a client or platform needs.
