@LeeC2202 Thank you for your explanation, however, I'm familiar with what you described. The issue I had (I'm sure it'll re-occur in the future) just did not show any afterburner lights at all in the editor no matter what, even when I allowed the video to play in game-camera mode It's as if the burners weren't even recorded at all (so strange).
Fortunately, I managed to record one scene of the KC-10A refueling plane and the B-1B Lancer together with the afterburner lights showing. It took me several tries, say for example -- 9 out of 10 times I had to redo the scene setup, check in Rockstar Editor to see if it showed up or not, and each time it didn't show up I restarted the game.
This problem is still unresolved, but I don't need to worry about it for now since the video is now complete. But for the future...I need this fixed.
