niceeeeee @ORTyOW ! I have also found a work around I meant to add here, if you drop 1 keyrame at frame xero on an attached rig rail, it seems to do the trick as well. Or at least, last time I needed to do camera on rig rail in sequencer that worked for me! Baking the entire transform works, the draw back of course is, very hard to make quick iterative changes with that style. It is not destructive but it certainly is something you do once you are fully committed to the look and feel of the camera.
Glad ppl are finding value here, love this community!! rock on all!
