Re: [FFmpeg-user] overlay with video offset not starting audio with same offset
I ended up taking this route. Worked like a charm. Create [s1]: aevalsrc=0:d=N[s1], where N is the number of seconds (to match video offset (itsoffset)) Concat [s1] and overlayvideo¹s audio (where [s1] is placed before [1:a]): [s1][1:a]concat=n=2:v=0:a=1[ovrla].

Re: [FFmpeg-user] overlay with video offset not starting audio with same offset
Thanks. Playing around with atrim and while the video processes, not only does the overlay video freeze in places (it¹s choppy), the audio is also off still. But I don¹t know if it¹s just an artifact of the video not processing correctly. I did notice that if I execute with offset 00:00:00.000 and without using the atrim filter, the video processes, the overlay plays cleanly.
