Consider using Resolve -> ffmpeg -> H265 in future, because it will enable a lot more control, and will definitely provide much higher quality if you use ffmpeg's software encoder, but may also provide some improvement even if you continue using HW encoding.Ĭ. But I'd be surprised if 10.15 was the only version supported.)ī. (We also don't know if 10.14 will be supported - he recommended to another macOS user that they upgrade to 10.15. We don't know what that means precisely - is it just not officially supported, or will it literally not run? But it's another reason to consider upgrading. Also we recently heard from Peter Chamberlain the BMD support guy that v17 will not support 10.13. This will definitely improve support for that GPU, eGPU usage in general, and HW encoding. ![]() ![]() That might end up being the same quality as Resolve, but there could be some room for improvement given ffmpeg will have more tweaking options.Ī. Then you can can either use the x265 software encoder - which will be slow, but give the best possible quality - or use 'hevc_videotoolbox', which is H265 using macOS' built-in encoding engine, which is what Resolve is also using. You could instead encode to an intermediate high-quality format like ProRes 422HQ or DNxHR, then use ffmpeg to encode that to h265. For reasons mentioned in 1, you might want to avoid using Resolve's H265 encoding completely. You might see some quality changes in 10.14 or 10.15, though I can't guarantee it, but I'd think you'd definitely get performance improvements at least.ģ. There have definitely been changes and improvements to the HW encoding in more recent macOS releases, as well as numerous changes to GPU drivers and general GPU handling, and eGPU. You're running 10.13.6, which is rather old. Sadly AMD's GPU encoders are not great quality to begin with, and I think I'm right in saying that the RX470/480 was the first generation to have H265, so it may not be that great.Ģ. It may simply be that the RX470 H264's encoder is better than its H265. ![]() In Resolve, H265 export is done on the GPU. I'm not an expert on H265, but the following things occur to me:ġ.
