Convert H264 to MKV
About H264
This is not a playable video file, but a raw video stream encoded with the H.264 (also known as AVC) codec. H.264 is the most widely used video codec on the planet, found in everything from Blu-ray discs to web streaming. A raw .h264 file is the pure video data without any audio or container information. It must be 'muxed' into a container like MP4 to be widely playable.
About MKV
MKV (Matroska) is a free, open-source container format that is known for its flexibility. An MKV file can hold an unlimited number of video, audio, and subtitle tracks, along with metadata, chapter points, and more, all within a single file. This makes it a favorite for storing high-definition movies, as it can contain the original video, multiple language audio tracks, and multiple subtitle files all in one place.

Frequently Asked Questions
What is the difference between H.264 and MP4?
H.264 is the codec—the algorithm that compresses the video. MP4 is the container—the 'box' that holds the H.264 compressed video, an audio track, and subtitles. Think of H.264 as the book's content and MP4 as the book's cover and binding.
How do I play a .h264 file?
Most standard media players cannot play raw .h264 streams. You would typically need a specialized player like VLC or use a tool like FFmpeg to combine it with an audio stream into a standard MP4 or MKV container file.
Is MKV better than MP4?
MKV is more flexible, as it's an open standard and can hold virtually any type of codec. MP4 has better compatibility, especially on mobile devices and streaming platforms. For storing high-quality video with multiple tracks, MKV is often preferred. For sharing and streaming, MP4 is the standard.
Will my TV play MKV files?
Many modern smart TVs and media players do support MKV files, but not all. Support often depends on the specific video and audio codecs used inside the MKV container. It's always best to check the device's specifications.
