H.266 VVC standard finalized

What sort of bugs do you hear about? Like it just slows down?

It's a bit of a rabbit hole. Just installing a Radeon VII in a 5.1 Mac Pro won't give you hardware acceleration. The 5.1 won't even allow installation of Catalina 'as is'. But there are a number of modifications that can be made. Kext hacks and installation of Catalina via Open Core.

I've done my fair share of hacks and modifications through the years to my Mac Pro, but I'm yet to do the Open Core installation since 'simply being on Catalina' wasn't good enough. But getting HW acceleration of HEVC would be a good reason since that is what my Mavic 2 Pro shoots.

You don't need to prove your point by repeatedly saying something is successful and made money.

Congratulations, but it has nothing to do with the camera and its compression.

I didnt shoot it. I was an assistant. (I shot some b-roll, did some boom opping and assisted the editor.) I'm definitely not trying to brag about the movie.

And obviously the film was better for having no constraints on shooting time. I'm not sure if that's a serious comment or not.

But it was a vision into how that world works. Budgets are tight, even on a budgeted project.

If they're spending $150k on labor costs (dp and editor) to make the movie, they dont want to spend $10k on hard drives. Which could easily happen considering that they backed footage up numerous times and used good drives.

Or me - I often back up my raw footage for 5 years or so. Sometimes a client needs something or lost their footage. So it's nice for me to have original footage in a compact form.

Then I have some wedding clients who want to save disk space and ask for HD in 28Mbps. They're planning on switching to 4K soon (assuming their business survives the pandemic) and I'm sure they will want the lowest bitrate codec with adequate quality in 4K.

But yes, when I'm shooting something with a lower shooting ratio or a bigger budget (which often go hand in hand), I would prefer a less compressed codec or RAW.

12:1 REDCODE and the smaller forms of BRAW sacrifice a lot of fine detail as well, you know. Life is full of compromises

That sounds hairy. What about an egpu to your MBP?

As I understand it, a humble Radeon 580X has the same h264/h265 hardware acceleration as the Radeon VII (which can playback and cut through 400mbps h265 like butter.

That’s a $200 USD investment (assuming you don’t need an eGPU enclosure) to remove any transcoding from the process.

This iMac has the Radeon 580 but it's doesn't say "X" so I am not sure if the X signifies a different or better version 580? This iMac doesn't deal with H.265 very well. It'll play it back in QuickTime but in FCP X, it chokes it up.

Sounds nice.

So, you confirm that HW accel. is actually working? I've read so many "yes, it's working" only to see retractions soon after, or at least some serious bugs.

Would be great with a reliable confirmation.

Yep, I can confirm. I’m running a stable build of Mojave through OpenCore 0.5.8 (and staying put on that build for the time being, since it does everything I need)

I'm having a devil of a time determining the differences between hardware acceleration on AMD chips.

But this chart on NVIDIA chips shows that there are different levels of H265 decoder acceleration in the sense that some chips only support 4:2:0 decode acceleration and some support 4:4:4. It doesn't have a column for 4:2:2. But it would certainly seem that not all H265 hardware acceleration is created equal.

I believe Grug has a X-T3, which is 10-bit 4:2:0 internally, so that would be interesting to know (especially if that's mainly the source/footage he works with using it).
 
It's interesting because I've been trying to think about how this very cheap card can make such a big difference for him, and it would appear to really make sense...4:2:0 vs. 4:4:4 (which would include 4:2:2).
 
Also - aren't XF-AVC and XAVC encoded using H.264? So can we really say that Fraunhofer compression is not suited for professional capture codecs?
