H.265: A New Standard for Digital Cinema?
A new video codec is expected to replace H.264 as early as next year. H.264 is one of the most common formats for recording, compressing, and distributing high-definition video, not in small part because it is the codec found on several HDSLR systems such as Canon’s EOS 5D Mark III. Another big advantage is that it is currently supported by for most video sharing websites like YouTube and Vimeo. Additionally, runs natively in both Lightroom 4 and Adobe Premiere Pro CS6, which dramatically decreases the time wasted transcoding and rendering files.
But, apparently there is (or technically, will be) a new kid on the block. The Moving Picture Experts Group (MPEG) and the Video Coding Experts Group (VCEG) are teaming up and plan to release H.264’s successor as early as January 2013. The new kid’s name will likely be H.265 or MPEG-H Part 2.
Just how much more efficient will H.265 be? Well, H.265 is expected to provide a significant improvement in data transmission and streaming efficiency compared to H.264. It will have almost twice the amount of compression ratio from for a similar quality level. This means that I’ll need to buy less memory cards, and less external hard drives. Both will make my accountant really happy. Below is the only video test comparing H.264 and H.265 we were able to find. It was performed on an Android tablet by Qualcomm, a San Diego-based chip-maker that is listed as a member of the international standards group developing H.265.
H.265 will be designed to support all new and current streaming technologies including devices working at 4K and Ultra HDTV (also known as 8K or 4320p) resolutions. Did you know that Ultra HDTV definition contains about 16 times the amount of pixels that are present in a 1080p video stream? That’s kinda insane! Check out the chart below to see things in perspective.
The H.265 codec sounds promising, but (there’s always a but) it will have to fight for widespread implementation with another codec called VP8. This format was purchased by Google two years ago and was released it as a royalty-free alternative under the Creative Commons license. Nvidia (Qualcomm’s main competitor) has built VP8 decoding support into its newer Tegra 3 chips alongside H.264 support, and several companies including Skype have adopted VP8 as their preferred format. Adobe also announced that the Flash Player will support VP8 playback in a future release. Who will win? Let’s wait and see.
