AMD CPU in Premiere Pro H.264 MXF Crash ！！！

[robert_9016]

大家好:我使用Adobe Premiere上遇到了一些問題，目前我訂閱CC正版，主要使用Premiere、Media encoder、Lightroom

電腦配置:

主機板-Gigabyte x670 Aorus Elite AX

CPU-AMD ryzen7950X

RAM-Crucial DDR5 5600 32GBx2
GPU-RTX3080 10GB
Premiere版本-V25.1

問題：我是一名紀錄片工作者，主要剪輯處得的素材大多為1080p、4K 10bit 422的H.264素材

1.當我在剪輯這些H.264的素材時，常常會非常卡頓，或是整台電腦當機，或是CPU/100%等等，這些都是很簡單的剪輯中發生的，尤其是在剪輯1080P的素材時，我不明白為何還有這種情況。

2.我在處理ARRI拍攝的Prores4444，LogC素材，已經進行色彩空間轉換成Rec709，卻在輸出時呈現Log畫面

3.25.1版本宣稱有H.264加速性能是支援AMD CPU嗎？


我的感受：呼籲Adobe正視AMD CPU的用戶，目前我聽到的很多消息都是Adobe對Intel的支援較好，但現在AMD的用戶非常多，沒理由不去優化你的的軟體對AMD的支援。

I run a Ryzen 3960x 24 core CPU, and a 2080Ti GPU. I get great performance but then I don't do much H.264 media and if needed proxy or t-code it. Normally I can just run it without proxy or t-code.

While AMD is finally shipping some CPUs with built-in long-GOP hardware, it hasn't made any sense whatever to get an AMD CPU, or an Intel KF CPU, as both of those don't have hardware long-GOP support.

"Adobe" can't fix what ain't in the hardware.

Now that some AMD chips can support long-GOP, i think they will need to make some changes in Premiere to utilize them more effectively

Hi @robert_9016 -  Thanks for submitting your bug report. We need a few more details to try to help with the issue.
Please see, How do I write a bug report?

What gpu driver are you using Adobe recommends using the "Studio" driver version when working in Premiere Pro.

Do you get a crash dialog box?

H264 10bit 422 files are only hardware accelerated with a Nvidia Blackwell gpu. you can view the RTX 50 series for options.

Sorry for the frustration.

感謝您的解答，看來h.264是最難編輯的檔案，目前我升級到了25.2感覺穩定性好多了，但是當我在編輯老舊的mpg檔案還是非常卡頓...甚至崩潰

Adobe急需解決檔案支援問題

我是使用Studio的驅動，並隨時保持最新的狀態，您是說50系列會有更好的編解碼性能嗎，在預算有限的情況下您推薦哪一款式呢?
