video - muxing stream encoding on h264 (interlace) with ffmpeg to mp4 -


mux stream mp4 container： when mux stream(720p) ffmpeg mp4,it works ok. when mux stream(1080i) ffmpeg mp4,the output file can not play normaly in vlc.the generat file have many snow points. have arguments not set right? there need special settings of parameters? waiting answer! thanks!

use ffmbc instead, if need mux interlaced stream mp4 container without re-encoding. recommended due quirk of how ffmpeg mp4 muxer works interlaced streams. see here details.

if you're ok re-encoding, use

ffmpeg -i input.mp4 -crf 18 -vf yadif -c:a copy output.mp4

adjust crf value quality/size tradeoff. lower values provide better quality @ expense of file size.
