Configuring x265 encoder
Hi All,
I am trying to configure x265 encoder for Random access reference structure with 7 B frame GOP (Hierarchical). But it looks like it is not possible to force a particular referencing structure in x265. Any idea how it can be done? |

I would like to ask about the function of the pass 1/2.
I thought that encoder X265 cuts preset for pass = 1 and always is 'medium'. However, recently draw conclusions that the pass = 1 and preset = slow / slower has other data in 'stats{log}'. It doesn't understandable for me is the action codec. X265 --pass 1/2 --preset slow --aq-streanch 1.0 --y4m --input-depth 10 --input-csp i422 --input-res 1920x1080 --output-depth 10 --fps 30000/1001 --bitrate 4500 --vbv-maxrate 10000 --vbv-bufsize 10000 {the figure is banding on his face}. X265 --pass 1/2 --preset slower --aq-streanch 1.0 --y4m --input-depth 10 --input-csp i422 --input-res 1920x1080 --output-depth 10 --fps 30000/1001 --bitrate 4500 --vbv-maxrate 10000 --vbv-bufsize 10000 {the figure is lower banding on his face (in another place)}. X265 --pass 1 --preset slower --aq-streanch 1.0 --y4m --input-depth 10 --input-csp i422 --input-res 1920x1080 --output-depth 10 --fps 30000/1001 --bitrate 4500 --vbv-maxrate 10000 --vbv-bufsize 10000 X265 --pass 2 --preset slow --aq-streanch 1.0 --y4m --input-depth 10 --input-csp i422 --input-res 1920x1080 --output-depth 10 --fps 30000/1001 --bitrate 4500 --vbv-maxrate 10000 --vbv-bufsize 10000 {banding almost disappears} How to properly inscribe the 'preset' function?
