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. The difference in output when I execute with the itsoffset and atrim is in the version with itsoffset > 0 and matching atrim, there¹s what appears to be warnings - for example, "[Parsed_overlay_1 @ 0x7fef18c21000] [framesync @ 0x7fef1900b028] Buffer queue overflow, dropping."
