Hello,

if i understand you want to use the Nvidia NVENC, in this case it's not the question if CRF or VBR ist better because Nvidia NVENC ONLY support CBR, VBR and CQP !! Yes with software encoder it's CRF but this doesn't work with NVENC.

For good quality with NVENC (as i wrote) it's necessary to use the lastest Gen of GPU. That means your graphicard must have an GPU of minimum the 6th Gen. -> Turing TU10x/116 or Ampere.

If your card (GTX1050) do not have that, i would not recommend to use NVENC.

Turing or Ampere make a big step to higher quality und less datarate. Only with this GPU types you don't need software encoder at high bitrates.

Yeah, you're quite right.

crf16 is better as VBR bitrate?

Yes, crf > vbr > cbr, but nvec is for speed, cpu is for Quality.

The problem with using a fixed bitrate is that each video is going to use it differently since each video has its own complexity, so in some cases that bitrate will be too much, just enough or too little.

Then use crf instead of cbr, I would say you start with crf 16.

lol, Youtube ≠ quality

only use crf.

the quality of each frame depends on the bitrate, so I'll say.

send pic(from video and mediainfo).

me too.

I like the interface just as it is now

Thanks a lot.

Hello, I'm using Voukoder 2.1.0(Premiere cc 2018) and I saw x265 doesn't have "ref" option or maybe I'm the only one who could not find it.

X264 has this option.

and x265 has this parameter:

Is it possible add this parameter?

Thanks in advance.

well, mine is

X264:

--level 5.1 --crf 16 --threads 0 --deblock 1:0 --bframes 16 --b-adapt 2 --ref 16 --qpmax 60 --rc-lookahead 60 --aq-mode 2 --aq-strength 0.7 --merange 32 --me umh --direct auto --subme 10 --trellis 2 --no-fast-pskip

x265:

--crf 16 --deblock 1:0 --bframes 10 --ref 8 --merange 44 --ctu 32 --me 3 --max-merge 4 --rdpenalty 2 --no-strong-intra-smoothing --rd 5 --rdoq-level 1 --limit-refs 0 --tu-inter-depth 3 --tu-intra-depth 3 --max-tu-size 16 --subme 5

but voukoder doesn't allow me to change reframes in x265.
