Part 4. FAQs on H.264 Compression

Does H.264 support HDR?

Unfortunately, HDR outputs cannot be generated from H.264 sources. If you wish to get HDR outputs, you must produce them from HEVC or H.265 sources. In fact, this highly efficient codec is supported among video-sharing video platforms catering to HD videos.

What is H.265 compression?

Less known as High-Efficiency Video Coding (HEVC), H.265 is the new coding standard for video compression. It promises to save bandwidth in a huge amount ranging from 40-45% over H.264 with similar quality.

Which is better, H.264 or H.265?

Both codecs are used for video compression. Which is better then? The H.264, known as AVC, is considered block-oriented. It works by processing motion-compensation-based video compression standards, also called macroblocks. On the other hand, H.265 processes information in coding tree units that process many blocks, specifically 64x64, to compress information more efficiently.


You could refer to the above guide to compress H.264 video files effectively and efficiently. The first program comes with stable performance and high compression speed. Besides, deducing the video size is successfully done without any internet interruption. Best of all, the video quality of the original file source is preserved, making it desirable for many users.
