Hi,

I want to transcode my full library of videos from h264 to h265 to save some space.

I installed Handbrake and started transcoding.

Now I wonder what is main difference between h265 (x265), h265 12-bit (x265), h265 10-bit (x265) and h265 (Nvidia NVEnc)?

I tested h265 (x265) vs h265 (Nvidia NVEnc) and Nvidia one is like 600FPS against 20FPS when using normal h265.

Is there some quality difference? Or its just because I have powerfull 1070Ti what accelerating whole process.

If you ever feel useless, keep in mind there's the 10nm i3-8121U

default h265 is 8bit, or the size for each pixel. Just copy that of the source

unfortunately NVENC is much worse quality than CPU encoder (unless you ditch bitrate for quality), that's why larger production groups use CPU only for their encoding.

NVEnc is really bad quality for a given bitrate, x265 is the one you want. 10-bit and 12-bit etc is for HDR. You're going to lose quality doing what you're doing because you're going from lossy to lossy.

Yes, I know, but I tested it on one 720p (5mbps) movie and original h264 is same as NVENC h265 (constant quality 21, encoder preset slow)

Mybe just my monitor not see the difference?

NVENC is terrible quality for same bitrate man, google it the entire internet will tell you. The only good thing about NVENC is that it's quick, definitely not the sort of thing you use for encoding videos.

10-bit/12-bit is the color depth of the encoded video. In the case of h264 10 bit is generally higher quality than 8 bit with the same file size, because it can be compressed stronger before getting noticeable banding (even though the source and display are both 8 bit). I imagine the same is true for 10/12 bit in h265.

So you guys saying not use NVENC at all even on best settings? Because even on constant quality 0 its still 10 times faster than general x265.

I personally not notices much difference on 720p movie but maybe it will me more visible in 1080p or when I will playback it on 4k tv
