There's quite a bit of info about using ffmpeg (more) to encode with x265: HEVC. However, when I try to encode my video from x264 to x265 with scaling to reduce overall bit rate in order to save even more space on my hard drive, I am still missing the Frame Rate Mode
option. Currently, my video after encoding has changed to CFR whereas it was originally VFR. The command is
ffmpeg -i input -vsync 2 -vf scale=1280:-1 -c:v hevc_nvenc -preset:v slow -crf 24 -rc vbr_hq -qscale:a 1
The output is OK, but I'm curious about the frame rate mode. Do you have any idea to output VBR with x265?
I am also curious about the information in this file, for I can understand some of the details, but not others.

on both files. I suspect a handful of frames had their duration regularized.
