I'm getting the "Failed: Video/audio codec" and I've looked at the FAQ about it, but still have a question. I have two video streams linked to the session, one is video channel 1, the other is video channel 2, and each of them export fine if you set them as the only video channel. However, when I try to use the PIP feature, I get the codec error message. From my reading of the FAQ, if it was a codec problem then one or other of the video streams would fail to export (and in fact when I first did the export, that was the case, so I re-made the offending video in lower resolution).
Do I need to make lower res versions of both video channels to allow the total video output to be within the capabilities of my phone? (BTW, phone is a Motorola g50, Android 11, with 20GB of free space)
