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!

    IMU, GPU encoding is for streaming: it aims at fast, not so great, output quality without CPU usage. Exactly what you are getting.

    Don’t use GPU encoding for storage… CPU encoding is much better.

    Edit: since its aimed at streaming, GPU encoding only needs to achieve real time performance, no need to go any faster. CPU encoding instead can go as fast as your cores can push.

      Yeah, I’ve done a bunch of reading since this post and I’m going with CPU. It may put a bit more stress on my system but my system was built for high-end gaming in the first place so I shouldn’t have any problems. Thank you for your input and information! :)
