FPS drops on file

Open SpyrosPsarras opened this issue 10 years ago • 2 comments

While I am recording, my actual video is running at around 70FPS, while the file is being captured at 34 at max. Also, here are my settings. Any idea? image Edit: forgot to mention. Potato CPU 6600@3400Mhz, 7890Ati Latest omega drivers, W10. Denominator is not 30, but 1.

Without resorting to some obscure weird trick that may or may not exist, sequentially processing the frame encode gives at best 45fps. Sometimes AMF has hard time meeting even 30fps. Weird.

A question, how long buffer does AMF/VCE have? Talked to one about NVENC and he noticed that if you let it buffer, or rather delay processing instead of insta-copy between RAM etc the performance goes up significantly (300->1000 fps in some cases i think), which would make 4k more realistic.

After reading that and asking about it i wondered if it would be viable in AMD VCE. He didn't know if it were as he is more focused on NVENC, but there is a chance it may be.

I don't know how AMD VCE works or how this AMF frameworks play it's role though, but is this something you know about jackun? If you want i can link you to the NVENC thingy.

Thanks.
