Convert H264 to HEVC
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 HEVC
This refers to a raw video stream encoded with the HEVC (High-Efficiency Video Coding) codec, also known as H.265. HEVC is the successor to H.264 and offers about 50% better compression efficiency, meaning it can deliver the same quality at half the file size. This makes it ideal for 4K and 8K streaming. A raw .hevc file must be placed in a container like MP4 or MKV to be useful.

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 HEVC/H.265 the future of video?
It is the current standard for high-resolution video delivery (like 4K Blu-ray and streaming). However, its adoption has been hampered by complex and expensive patent licensing. Newer royalty-free codecs like AV1 are competing to become the next universal standard.
Why do I get an error playing an HEVC file?
Playing HEVC video requires either hardware or software support for the codec. Older devices may not have the necessary hardware decoders. You may need to update your media player, install a codec pack, or use a modern player like VLC that has built-in support for HEVC.
