I found this on Puget systems site. Full credit to them. This explains alot of why my drone footage plays well, while my Canon R6 plays poorly.

Hardware or GPU

Adobe's engineers have just added some more to the HEVC support equation if you have the right Intel CPU. Details of the public beta HEVC additions in the following link to their public beta forum.

Neil,

Thanks for posting the link. I have nothing aginst AMD but when it comes to Premiere Pro I have to recommend Intel CPUs with an IGPU because of the Quick Snyc features. I don't doubt Abode has an M1X chip and Alder Lake CPU for testing purposes. I think we should see some benchmarks soon. I think Window 11 hits the stores next month.

That chart should be a sticky that we can link to if people are having problems editing video from a drone or DSLR camera. Not all H.264/265 is edited the same. Having said that I would like to think Premiere Pro will take full advantage of the 10nm Adler Lake CPUs. Some leaked benchmarks suggest it will be a huge improvement over the old and wornout 14nm chips.

I am sure most people are hip to the benefits of Nvenc and Quick Sync but if not the video below might be helpful. I think they both work great but I admit I would like to see more H.264/265 variations supported ASAP.

That chart should be handy to have. I always post that Nvenc and Quick Sync cannot play all the odd variations of H.264/265. I don't doubt in another 2-3 years they will support even more variations of H.264/265.

Go over to Puget systems and look at the codecs supported by Resolve. With Gen 11 Intel CPUs, quick sync suports ALL of the various codecs.

I sure hope Adobe gets moving on this.

I'd say you're in the minority if all you do is work on feature films. Lucky you. And it still doesn't address the fact that Premiere Pro is clearly lagging behind it's direct competition. In any industry that's what we call a bad thing.

I'm not sure it's ever a bad idea to follow the standards set by broadcast, cable, streaming, and feature film; be it for smooth and fast post-production or a good paycheck.

Last I checked, Final Cut Pro only supports native H264/H265 if it's been recorded on an iPhone (which should be supporting shooting ProRes soon); otherwise, it's converted to ProRes for both Optimized and Proxy making it easy to edit on just about any Mac even with modest amounts of RAM. Avid Media Composer converts H264/H265 to DNxHD upon ingest and that very process is what's made Media Composer a very stable platform and industry standard for decades. Resolve only offers acceleration if it's the paid version. GoPro acquired Cineform to provide good editing CODEC and support ProRes.

Even the better implementations of H265 are not meant to be used from start to finish in a workflow. And most H264 is low bitrate, low color depth, long GOP, interframe, shallow PSNR... what am I missing?

There's no shortage of issues in these forums and the Resolve forums that go away with transcoding to a CODEC that's good for editing.

Hi @Andy Urtu,

We have enabled Hardware Acceleration decode of HEVC/H264 4:2:2 10 bit on Mac ARM systems in the latest Premiere Pro Beta builds. We will also look into other platforms.

Please download the latest Premiere Pro Beta build from Creative Cloud --> Beta apps --> Premiere Pro (Beta)

You can have a look at the announcement here:

Please let us know how it goes for you.

Thanks,
Mayjain
