TX2 CSI Capture with Jetpack 4.5.1

Interesting. These sizes appear correct (below) and using 3.2.1, we know this video is 720p. 1280x720 is what V4L reports as well. You mentioned the metadata lines above, but I assumed that was a cut and paste error from the original post. Should I try 4 lines as shown there?

I know some of these sizes are odd looking, but they are correct, for our use case. SDI has interlaced options, which we transport over the CSI as two “frames (fields)” and recombine the fields to get a full frame.
