Why Convert H264 to MKV file?

An H264 file holds raw video encoded with the H.264 codec, but on its own it is a bare stream that many players and editors will not open. Wrapping it in an MKV container turns it into a playable video in a flexible, modern format that supports multiple tracks and subtitles. Converting H264 to MKV packages the stream so media players and tools can handle it.

Because the video is already H.264, the conversion is fast and keeps the picture quality intact — it is repackaging rather than re-compressing. The result is a versatile MKV favored for quality video and media servers. If you need the widest compatibility across phones and websites, MP4 is safer, but for a flexible container from a raw stream, MKV is an excellent choice.
