@gzhls 使用VBR, 2次编码看看,对录屏的压缩非常显著。
代码:
Two-Pass Example For two-pass, you need to run ffmpeg twice, with almost the same settings, except for: In pass 1 and 2, use the -x265-params pass=1 and -x265-params pass=2 options, respectively. In pass 1, output to a null file descriptor, not an actual file. (This will generate a logfile that ffmpeg needs for the second pass.) In pass 1, you can leave audio out by specifying -an. For libx265, the -pass option (that you would use for libx264) is not applicable. ffmpeg -y -i input -c:v libx265 -b:v 2600k -x265-params pass=1 -an -f null /dev/null && \ ffmpeg -i input -c:v libx265 -b:v 2600k -x265-params pass=2 -c:a aac -b:a 128k output.mp4 Note: Windows users should use NUL instead of /dev/null and ^ instead of \. https://developers.google.com/media/vp9/settings/vod 此帖于 2021-02-18 09:04:00 被 fatality 编辑. . |
