The binding video codec, audio codec, etc.. is not working

[coldholic]

I am trying to use filebot, but I realize when I try to create the expression, I got some error. And I can't get the video codec and audio codec after renaming. Is there anything I need to set?

Where would the data for {vf} {vc} {ac} come from? I guess you need to set a sample media file. How? Just try every single button on that UI and you'll probably figure it out in less than a minute.

{lang} is only defined for subtitle files. It will not work for video files.
