[FFmpeg-user] overlay AND concatenate with ffmpeg - merging to one command?

[Chad Horton]

Correction on my inputs for both executions:

ffmpeg -y -i baselinevideo.mp4 -itsoffset 00:00:0.0000 -i overlayvideo.mp4
-filter_complex 
"[1:v]scale=1280:720[ovrl];[0:v][ovrl]overlay=eof_action=pass[outv];[0:a][1
:a]amix[outa]” -map [outv] -map [outa] -vcodec mpeg4 -strict experimental
finalvideo-temp.mp4

ffmpeg -y -i finalvideo-temp.mp4 -i concatvideo.mp4 -filter_complex "[0:0]
[0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a]" -map [v] -map [a] -vcodec
mpeg4 -strict experimental finalvideo.mp4
