New H.265 twice as efficient as H.264!

[Bishop_99]

Are there any programs available right now that will let you encode videos in HEVC? I'm really curious to see how efficient it HEVC really is, but I have no such option on my Sony Vegas. I would like to re render some 1080p home videos and see how low the bitrates can go before it looks bad. Also curious to see if it's more cpu hungrier than AVC in the encoding process.

x265, DivX HEVC, Strongene have all been publicly available for more than a year. The test model has been available much longer.

If you are a beginner, probably the easiest way to test HEVC encoding is x265 via a Handbrake nightly.

Thanks. I remember trying the Divx a while ago, but the HEVC/.265 option wasn't available yet to encode. I'll look it up or the others as well and give it. I do a bit of video encoding so I'll go with the others first.


I gave the Divx HEVC a try. Max bitrate is 12Mbps and the 1080p HEVC video looks worse than the original 1080p MP4 video at 35Mbps. I'll try one of the other converters.

I mean, if they really desire to be well-informed and equitable as to ‘standards’ organizations, they should also use the designation ‘ISO/IEC 23008-2 MPEG-H Part 2’ where the HEVC standard is also defined, or at least MPEG-H Part 2 but I guess that’s too long to type out; plus, these days with B.T. 2020, the ITU is currently the ‘flavor of the day’ rather than the MPEG (http://mpeg.chiariglione.org/standards/mpeg-h

So, now that we've gotten that ^ designation properly straightened out, in regards to HEVC , for advanced users/readership there’s a new book out…http://www.amazon.com/High-Efficienc.../dp/3319068946

Editors include Vivienne Sze (Assistant Professor at MIT), Madhukar Budagavi (from TI), and Gary Sullivan (longstanding chairman or co-chairman of various video and image coding standardization activities quoted or linked to previously in this HEVC thread).

from the 1st paragraph..." HEVC is also expected to deliver next generation higher resolution HDTV video by broadcast, streaming, download, and 4K Blu-ray™ for 4K and 8K Ultra High Definition TV."

It would be interesting to know if the term 4K Blu-ray™ has indeed been trade marked. IIRC, the term Blu-ray has been trade marked for some time now.

Sony, Panasonic, LG, etc. still MIA in regards to MPEG LA HEVC patent portfolio.

Well, out of the listed 23 enterprises owning essential HEVC patents, can anyone guess as to which entity (out of the 23) holds the most of them?

When VP9 gets 12-bit profiles that might put a bit more steam behind having a single license for HEVC.

Based on the list of HEVC patents it would currently be SK Telecom.

[Penton-Man]

Well then, can anyone guess as to which country slots in as having the most of these portfolio patents?

An Undiscovered Country.

I have no idea, but would guess an EU country, Sweden?

SK Telcom is South Korean so it could be them.

[Penton-Man]

South Korea wins the total number prize…by a landslide.

You many be right but I don’t recall LG having essential HEVC IP, the others more so.

Until then, these companies (Sony, Panny, Microsoft, Qualcomm , Ericsson, MediaTek and one other that I’m blocking on) I believe have already established their own IP licensing programs including cross licensing; therefore, it’s assumed they currently do not desire to participate in the HEVC patent pool.

However, pursuant to their membership in JCT-VC they are obligated to license their HEVC standard-essential patents (SEPs) on fair, reasonable, and non-discriminatory terms anyway.

The final specification for 4K Blu-ray won't be released until next year but the current plan is that it will use HEVC to support 10-bit video with resolutions up to 4K at 60 fps.

will that be 4:2:0 like we have now, 4:2:2, or 4:4:4

It will be 4:2:0.

I can see it being 4:2:0 because there wont be anything for 8K if they go 4:4:4. Also if they go Rec. 2020 and 4:4:4 8K will have to CIE. 1931 colour space, otherwise it will just be more of the same pixels. Can you go higher that 4:4:4.
