H264, commonly known as Advanced Video Coding (AVC) or MPEG-4 Part 10 is among the latest compression standard for videos. This is a block-oriented method that can deliver high-quality videos while reducing the storage space up to half and keeping the bit rate low. H264 is a practical and relatively inexpensive method and can support videos in 4K and 8K UHD as well.

Though H264, MP4 may be considered to be quite similar to many, technically, they are different. At the same time, H264 is a coding format that is used for compression, recording, and distribution. MP4, on the other hand, is a video container format that is capable of storing video, audio, and other multimedia data. Thus, H264 requires a video container to host the encoded video, while MP4 is a container format in itself. Though H264 majorly uses AVC to encode the files, it can also be encoded in other formats like AVI, MOV, and MKV.
