Resize a Video |
The video format H.265 compresses a video stream whilst well retaining
the quality. Here a video is input with -i
, converted to
the video codec H.265 (libx265) with -vcodec
,
using a Constant Rate Factor of 28 with -crf
(24–30 is a
good range, with lower values giving better quality but larger files).
$ ffmpeg -i myvideo.mp4 -vcodec libx265 -crf 28 smaller.mp4 |
