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.

Niel,

No one is suggesting Nvenc and Quick Sync are bug free but the whole purpose of Nvenc and Quick Snyc is to edit native H.264/265. Talking about transcoding to Pro Res or Cineform on a thread about Nvenc and Quick Sync is counter productive to the purpose of this thread. If someone's system is malfuntion I agree transcoding would be wise but this thread is about the benefits of supporting Nvenc and Quick Sync as opposed to helping trouble shoot a person's editing system. That being said I understand Warren loves to transcode to Pro Res. I also understand Warren does not think H.264 should be used for editing. Starting a new thread about the benefits of transcoding to Pro Res and smart rendering for those without Quick Sync or Nvenc hardware would be great but this thread is about editing and rendering H.264/265.

If using H264/H265 for acquisition, the bit-rate should be at least 35 Mbps for professional work. Depending on the intended use, it's likely that the color depth should be as high as is supported by the camera being used.

If delivering to H264/H265, the default settings in Adobe Media Encoder follow the recommended guidelines for common platforms and typically do not need to be adjusted. However, as these tend to be in the 8 Mbps to 12 Mbps range, using these exports as source footage later should be avoided.

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
