I’ve pirated every video converter known to man (UniConverter, WinX, VideoProc, Aiseesoft, Tipard, etc) & even tried open source tools like ffmpeg and handbrake and I can’t get hardware acceleration to work unless I just don’t understand how it’s supposed to work. I have a Radeon ™ RX 470 graphics card and plenty of processing power.
An example is when I attempt to convert a video to HEVC and don’t use acceleration, I can get like 100 FPS and 2-3 mins rendering time but all my CPUs go to over 100%.
However, when I turn on acceleration or use the AMD HEVC Encoder (ffmpeg, handbrake), the FPS rate drops to like 10-15 FPS, the CPUs barely go over 10% and the GPU then jumps to over 100% which is fine but then it tells me it’ll take like 20 mins to render a 20 mins tv episode!?!?
This is driving me crazy. Can someone provide some insight on this? I’d be forever grateful. Thanks!
AFAIK x265 encoder support has always been flaky with AMD GPUs. I used to get constant stuttering when trying to playback HEVC files with my old RX570 before switching to a 1080TI. I think Nvidia or Intel is your best bet for this.
