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
