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.

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.

Warren,

If people ask me if Premiere Pro supprts Nvenc and Quick Sync my response is always a big "yes" with some limitations. I never respond by saying H.264 is not an editing codec or suggesting they learn about color sampling, color depth, interframe encoding, compression generation loss, and - perhaps most importantly - peak signal noise ratio. Why do you think we have two totally different responses?

No one is saying H.264/265 is the best video codec but H.264/265 is the most popular and can yield good results. It is used in cell phones, DSLR cameras, screen recording software etc. Intel and Nvidia are aware of this fact and decided to implement hardware encoding and decoding so people can edit the native H.264/265 video files on their laptop an upload to social media sites. No one is denying transcoding to Pro Res is useful to your workflow but you have to admit Quick Sync and Nvenc are handy to have for people who want to edit H.264/264. There is no need for the average person posting to soical media to be concerned about NTSC, ATCS, 4:2:2 or Pro Res as you suggested. Most people are not creating a movie of the weak for NBC and smart rendering is a non issues for people who post short five minute long videos to social media. No one has stated transcoding to Pro Res or Cineform cannot be useful but for millions of people with Quick Sync and Nvenc it will be counter productive.

Smart Rendering vs. Hardware Encoding in 2021

If you have a newer Intel CPU that features smart rendering and a GPU that supports hardware encoding, with H.264 fooage, an export which uses "Hardware Encoding" and 1 pass VBR may be fast enough to be satisfactory for most editors.

You may wish to do a speed test between the H.264 and the ProRes (or what have you) to see if there is any advantage using one workflow over the other.

Keep in mind Nvenc and Quick Sync will get better and better not worse. Do you kind of see my point? Will AMD CPUs get something like Intels Quick Sync? Who knows for sure?

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
