user13870: I am trying to specify multiple filters for ffmpeg and I am getting an error output.
I am trying to do an audio and video fade in and a resolution scale.
my command is as follows...
ffmpeg -i 00021.MTS -c:v libx264 -preset ultrafast -crf 0 -vf fade=in:0:500, afade=in:0:300, scale=384:218, scaled.avi

and the error it gives me is as follows.....

[NULL @ 0xb72ce0] Unable to find a suitable output format for 'afade=in:0:300,'
  afade=in:0:300,: Invalid argument


user1871: Audio and video filters are invoked in separate chains. And without enclosing quotes, whitespace will break the chain.
ffmpeg -i 00021.MTS -c:v libx264 -preset ultrafast -crf 0 -vf "fade=in:0:500, scale=384:218" -af afade=in:0:300 scaled.avi
