  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Youtube's VP9 4K streaming Codec + RED

Peter Salvia said:
Here's a quick update with some general info about VP9, working on getting more specifics about bitrate, etc. If there's anything specific folks here would like to know post it and I'll work on getting answers.

• VP9 is making YouTube play faster, smoother and better in quality, as we ramp up deployment globally
• Smoother: VP9 has improved buffering by 25% in developed markets & 100% in emerging markets
• VP9 deployment: VP9 represents 60% of Chrome video playbacks on desktop
• Better quality: VP9 has increased YouTube HD delivery by over 25% in emerging markets
• Faster: VP9 has reduced HD playback latency by 15% everywhere
• VP9 is enabling YouTube reach the next billion people in emerging markets
• VP9 gains across the board more pronounced in emerging markets
• VP9 has broad industry adoption with now over 20 major TV, mobile & PC partners supporting it in their products starting 2014.

Here are few partners leading VP9 adoption:

• Ittiam VP9 OpenCL decoder is available now, link to press release here
• MediaTek & Sigma TV chipsets with VP9 support will be available in 2014
• LG & Samsung TVs with VP9 support will be available in 2015

Got any news about Broadcom? They have been dead quiet about their VP9 efforts and there's a big demand for VP9/HEVC add-in decoder cards in the Linux markets where older low-end hardware is typical and many people outside the US bought their CrystalHD VC1/H.264 decoder cards to use in notebooks/netbooks/nettops.
 
Hmmm... VP9, 4k on Youtube right now and the next thing is AndroidTV. Google has good cards, they could start selling movies and tv-shows in 4k via their play stare anytime.

huh? I'm not talking about watching the video on youtube... It was about downloading the AME preset file from Mega...

The RED channlel videos played very well in Chrome for me. Didn't try it in anything else.

Whoops! Sorry got the wrong end of the stick! ;)
Strange that you needed another browser to download the link but such is the way of the internet! :)

This doesn't work for AME 5.5. Would you mind screen capping the A/V settings?

Sure thing Doug, here you go...

YouTube has switched to VP9 encoding for all 4K uploads, as of the end of last month. Footage uploaded before the switch will remain as is, for the time being.

Quick question: Does this entail any change from the uploader part? Should we still deliver from Resolve or Premiere at h.264?

Anything you upload for 4K output gets put through VP9 re-encoding, so there's no point in uploading VP9 from the beginning, if that's what you are asking. Just keep doing what you've been doing and remind your clients (or anyone else of import) that they will need to use the appropriate web browsers to view your new footage at 4K. I expect down the line that YouTube will put all the H.264 uploads through re-encoding, but that's likely 2-3 years out, if ever. The new AV1 codec - successor to VP9 - is supposed to be released sometime this year, with hardware coming at the end of next year, so things are murky in regards to YouTube's future.
 
Thanks for the notes L. Langer. Is it just me, or does it seem like we are always waiting for the next codec to drop? After the HEVC Advance patent trolls derailed the H.265/HEVC rollout I was really hoping VP9 would fill the void quickly. Sometimes it feels like some of the stakeholders are deliberately slowing things down, it's almost like they want to ROI their HD hardware investments before 4K/UHD becomes the expectation... ;-)
