• Extracting mp3 from mp4 via FFMPEG doesn't apply audio bitrate

  17 juillet 2021, par Mohammad Zamanian

  I want to extract a simplified mono low bitrate low frequency and basically low sized audio from any mp4 file. I use the following FFMPEG command but the resulting audio somehow has 2 channels and its bitrate is the same as the original audio from mp4.

  


  ffmpeg.exe -report -y -i "{mp4}" -vn -acodec libmp3lame -ac 1 -ab 64k -ar 24000 -f mp3 output "{mp3}"


  


  Here is my report :

  How can I force the desired audio bitrate ?

  


  Also, why is there 2 outputs called Output file #0 and Output file #1 and why the #0 doesn't have any path ?

  


• why ffmpeg only combines first 390 images when combining very large amount ( about 9k) images into video ?

  4 juillet 2021, par Siwei

  I have a VCD, and I split it into nearly 10,000 images, named like :

  


  $ ls tmp_enlarged_image_folder

vcd3_00000001.png
vcd3_00000002.png
vcd3_00000003.png
vcd3_00000004.png
...
vcd3_00089998.png
vcd3_00089999.png
vcd3_00090000.png


  


  and the following command doen't work for me :

  


  ffmpeg -loglevel trace -f image2 -r 25 -pattern_type sequence -i 'tmp_enlarged_image_folder/vcd3-%08d.png' -vcodec libx264 test.mp4

• 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 ?
