I don't know much yet about the intricacies of the H265 format, but what you intend to do seems rather pointless, as you will either lose quality (and at least for now compatibility with most hardware players) or actually increase the size of said library, which definitely defeats the purpose. Do you recommend using VAAPI HW encoding for this use case? I know SW encoding is almost always better (in terms of quality) than HW encoding, but HW encoding is just super faster than SW encoding. What is the equivalent H265 CRF for H264 CRF of 18?ĥ. How about 4:2:2, where is it mostly used?Ĥ. 4:4:4 is almost only used when either using your TV as a PC monitor or using it with console games with a lot of texts. For chroma subsampling, 4:2:0, 4:2:2, or 4:4:4? I'm reading that for movies and tv shows where you watch a couple of feet away from the TV, 4:2:0 is more than enough. Is this accurate and should I go for 10bit?ģ. For bit depth, 8bit, 10bit, or 12bit? I'm reading that 12bit is overkill and 10bit is actually very good for HDR.

What is the difference between intra (main10-intra) and non-intra profiles (main10) in H265? Are there any other H265 video profiles that are available with FFMPEG?Ģ.

I'm planning on using FFMPEG to convert everything to H265 but have a couple of concerns in doing so.ġ. My media library is composed of all H264-compressed movies and tv show files.
