I've been making many videos for a while now and I've improved on it a lot. I can't really see the first video being able to be pulled off in BC since it uses many complicated camera angles in which you need to follow the ships or weapons fire. It's nearly impossible to predict that in an AI fight in BC.
As for the second video, it's possible but difficult. Most of the views in the beginning of that video is doable but not all ships will have different movement. Mostly going in straight lines, but the camera could follow them similarly as the video is. Towards the end is more complex but something similar could be performed in BC.
So all-in-all, first one is pretty much impossible in BC but the second one is plausible.
