• ffmpeg converting .vob to .mp4 --- colors are washed out

  28 mai 2021, par Blattla

  I am very new to ffmpeg. Currently I am trying to convert old family movies from vob to mp4.
After getting some help I used this command :

  


  ffmpeg -i 1998.vob -codec:v libx264 -crf 17 -pix_fmt yuv420p -codec:a aac -movflags +faststart 1998.mp4


  


  Two things that still bug me. The output is almost 20% larger than the input and the colors are washed out. Although the movies are old and of low quality (grainy, rather flat colors, ...) the colors in the output movie are less intense than in the original one. Larger file size would be ok for me but do you have any idea which part of my command might cause the color issue ?

• Concat failing with ffmpeg 5.0 vs ffmpeg 4.1.1

  16 avril 2022, par Woolwit

  I have ffmpeg 5.0 installed on a new Silicon M1 Mac Mini running Monterey and concat is failing with the same command that has served me well on ffmpeg 4.1.1 lo, all these many years. Anyone have an idea why this command would fail on the newer version of ffmpeg.
This is with the exact same mp4 files. The ffmpeg 4.1.1. completes the concat in less than a minute.

  


  ffmpeg -i vid1.mp4 -i vid2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4



  


  Thank you !
