Thanks for those replies! I’ve tried several options without success.
@pbattersby : option 1 doesn’t work since the “overlay” size is different. The overlay only is 1280x100 vs 1280x720 on the primary video. I tried option 2 and this seems to work, thank you!
@MusicalBox - thanks for that additional option
@Ar_D - Thanks, unfortunately I do not have Blender.
