Convert H264 to MP4
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 MP4
MP4 is the most widely used video file format in the world. It's a multimedia container that can store video, audio, subtitles, and images. Its success is due to its excellent balance of high-quality compression, which results in relatively small file sizes, and its universal compatibility across virtually all devices, browsers, and platforms. It most commonly uses the H.264 video codec and the AAC audio codec.

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 MP4 the same as MPEG-4?
Not exactly. MPEG-4 is a compression standard, while MP4 is a container format. An MP4 file often contains video compressed with the MPEG-4 standard (specifically, codecs like H.264), but the MP4 container can also hold video encoded with other standards, like H.265.
Is MP4 better than MOV?
For general use, especially for web streaming and sharing, MP4 is better due to its universal support and smaller file sizes. MOV is a professional, high-quality format that is excellent for video editing, especially within the Apple ecosystem, but it is less compatible and results in larger files.
