Good evening to the whole team!

I have a huge problem for a week now. I made a new computer strong enough to be able to work my files in full resolution but as when using the files of Sony A7siii 4k 120 fps 4: 2: 2 (10bit color) mp4 in premiere the premier uses 100% CPU / 14% GPU and I have LAG in Playback.
When I use a Sony A7siii 4K 4: 2: 0 file (8 bit color) it works perfectly (pemier use 13% CPU / 50% CUDA & NO LAG in Playback). So the problem is 10bit color! Is there a solution to this? I have been contacting the company for 3 days now and they do not find me a solution!

PC specs:
11th Gen Intel (R) Core (TM) i9-11900 @ 2.50GHz turbo 5.20 GHz
RTX 3080 TI (10G Ram)
128 giga ram on board
Windows 11

having the same probome. clearlin my case its is the 4:2:2 as well.
trying to fix and convertying the files to 4:2:0 so i can get on with my life.
it is a clearly Premier issue and not my workstation. really a waste of time. soory

The easiest fix is (if you work on aa laptop) Unplug the Power cored. CPU will be normal again.

Update- Premier didnt work well with the Proxies, firs did not sent to En properly, than after updates. it did but when the files were converted into proxies the 100% CPU issue apears again. than when rendering the project again 100% CPU, every time Premier read the 422 files it shoots up to max CPU/

Will never get 422 into premier again. next time wont Proxy at all. will convert the files into H264 420

when the power cord is unplagd th GPU goes into 100%

I just tried files from the page below and they still work fine on my machine. Is there some difference in these file:

There is acceleration support on the 12th generation of Core 9 processors. Everything below is sorry, climb to 4:2:0. I myself experience inconveniences when working with 4:2:2 on Core 9900K. This is crazy

I encountered the same problem as you, I tried to shoot multiple videos in different formats and import them into PR for preview. The result is that no matter which encoder is used, the 4:2:2 video cannot be previewed normally, because the PR cannot call the GPU of the graphics card for hardware acceleration, and has to rely entirely on the CPU, which will exhaust the resources of the CPU and cause Stuck and stopped. I guess that's the reason for everything, the current latest version of PR doesn't support hardware acceleration for 422 video.

The only solution is to create a proxy file, or forgo shooting 422 video and use 420 instead. It depends on your needs, if your video needs careful color correction then shooting 422 and creating proxies takes extra time to spend. If your video does not need careful color correction, you can just shoot 420 directly, which will save time in post-production.

BTW: You can

Use can use Shutter Encoder to convert the files to a more edit friendly codec. Maybe try ProRes LT or even PROXY format within Shutter Encoder for easy to edit formats with 'better' files size. Or ProRes 422. I tried them all with your sample clip, and the all work well and convert quickly.

Also, you can use a proxy workflow which works very well in PP. Use ProRes or Cineform proxy files.

Sorry if I missed it, but what are your sequence settings? I can play your video well on 24 and 30fps sequences, but it drops frames with a 120fps sequence. I used a more typical sequence 24fps - and slowed the clip down to 20% and it played well in slow motion also.

Thanks so much for your tip MyerPj!

Unfortunately I have tried it but it still does not work ... (I add screenshoot). The computer is too strong to be affected by 120 FPS. I have tried the 25FPS file and again it raises the CPU a lot. The problem is that in the 10BIT file the premier pro uses 100% of the CPU and very little of the GPU graphics cards.

It makes a huge impression on me that the premiere can not run the files of a mirroless camera while a player in windows runs them with minimal CPU usage .... Disappointing ...

Here is the report when the same file (10BIT 120Fps) run in a player on windows without premier pro(60%CPU used check screenshoot). there is some explanation???

Hi Stamatis,

Sorry for the disappointment with the performance of Premiere Pro and those files with your system. I think that your computer should be able to support playback for your files with your 11th gen Intel CPU/GPU and Quick Sync providing hardware decoding. Your GPU will not yet support the format, however, for any decoding. See this article: https://www.pugetsystems.com/labs/articles/What-H-264-and-H-265-Hardware-Decoding-is-Supported-in-Premiere-Pro-2120/

The problem may be that 24fps would be supported but perhaps 120fps might not be. You could try a test with a clip and see if it performs OK.

Sorry about you not getting help from our staff. Feel free to message me if you would like to escalate your case.

Thanks,
Kevin

Good evening Mr. Kevin-Monahan!

First of all, thank you very much for your time on my problem!

Unfortunately I have tried? All the fps ... The problem is clearly 10Bit (4: 2: 2). I am very disappointed as I made a big investment in camera and computer and I did not expect that the program will be what it will not be able to afford .... The strange thing is that the premiere can not work the files of one of the most famous cameras ( Sony Asiii) which has been on the market for almost a year ... I am really very disappointed and I am seriously preparing to change the editing program ...

Changing editing programs may not help. Some video codecs are hard to playback and you are pushing 120 FPS. Keep in mind Premiere Pro does support Nvnec and Quick Sync some NLE do not. Having said that did you try Quick Sync instead of Nvenc? If so did one work a little better than the other?

Premiere Pro does not support all the variations of H.264/265 when using Quick Sync or Nvenc. Some variations of H.264/265 can bring a 12 core CPU to it's knees. Having said that I think Adobe did state the M1 chip and Alder Lake will support more variations of H.264/265. For H.264/265 it is hard to beat dedicated hardware for encoding and encoding. The video below shows the power of Nvenc and Quick Sync. That being said try using Quick Sync instead of Nvenc. It might support 10 bit 4:2:2 and prove to be better on your system than Nvenc.
