Part 3. To Know More about H.264

1. H.264 vs HEVC, what's the difference?

H.264/AVC can encode video with approximately 3 times fewer bits than comparable MPEG-2 encoders. It brings incredible quality and efficiency. While the successor HEVC, a new standard video compression, delivers bit reduction of approximately 60% of 4K compared to H.264. Since nowadays more phones, camcorders or so are taking videos at higher resolution up to 4K, HEVC compression is even more crucial. But for a better playback and sharing, it's better to convert the 4K HEVC recorder to more compatible H.264.

2. Is H.264 the same as MP4?

Obviously, not. H.264 is a standard of video codec, a popular compression for HD video, which achieves high quality video in relatively low bitrates. It's widely used in AVCHD camcorders, HDTV, Blu-ray, and HD DVD etc. While MP4 is a container format, full name is MPEG-4 Part 14, written as .mp4. MP4 (.mp4) is one of the H.264 encoded video formats.
