The file opens and the content in 1_tmp.avi plays fine, at the same quality, but when it gets to the point in the video where 2_tmp.avi should be, it’s pixelated static all the way through (see image below).
If I use a command like :
ffmpeg -i 1_tmp.avi -i 2_tmp.avi -filter_complex "[0:0] [1:0] concat=n=2:v=1 [v]" -map "[v]" output.avi
I do get full output of both videos merged together, but it is dropped to an mpeg codec and the quality loss is noticeably prominent.
