the n=2 is a typo and should be concat=n=3 right?

@xpt Please provide a link to a pastebin site showing the complete output of ffmpeg -i input1 -i input2 -i input3

Perfect! I didn't look closely, :-) One more question, I'm still trying to figure out the exact syntax. Could you give another example that need to combine three files together? I got the part [0:0] [0:1] [1:0] [1:1] [2:0] [2:1], but moving onto the concat=n=... part I'm not sure there. Also, the wiki have more space, while yours have some extra ;. Neither of them matters right? THX!

@xpt My example command has the scale in it. You can do everything in one filtergraph, so no need for multiple -vf, -af, -filter, or -filter_complex.

What an amazing reply. Thanks. Alright, I was hoping to avoid the most complicated one if possible. OK. Hmm..., hold on, I got this while trying to use -vf scale=960:-2: -vf/-af/-filter and -filter_complex cannot be used together for the same stream. Is there any way to get what I want to do in one step (concat & scale down)? Else, would that means concating with demuxer is the only pre-prepare option now? Thx
