In today’s blog, owner of Antrica, Les Litwin shares his expertise of encoders and decoders, once again. This time, he discusses the differences between the two most common video compression methods – H.264 and H.265. He explains the suitability of both options to help you make a more informed product choice.

H.264 is a method for compressing video so that it can be sent on a standard network without using a lot of bandwidth.

H.265 is a more up-to-date, more efficient way of compressing that video into a lower data rate. It was primarily invented for the 4K movies because 4K movies were four times as much data as the old 1080p HD movies, so they needed to find a compression method that reduced the bandwidth.

H.264 and H.265 are basically the same sort of type of compression method – As I say the 265 is just more efficient. Where does h.265 come in? As I say, 4K movies, TV, but also at the very very low data rate, so if you were wanting to send video to a mobile phone that was in a poor network area, H.265 would give you a much better video than H.264 at these very low data rates.

In the middle, which is mostly where security-surveillance live, there’s very little difference, there might be a 10% improvement using H.265 compared to 264, so actually 264 is still the predominant standard across the security industry for that reason.
