Take a look at Rise of Flight
There was an old playstation game - stunt driver - that let you do a driveby, then save it and remix the camera angles and cuts. It was pretty cool, but to make that sort of thing work you have to store a lot of state.
If you want in-game movies get a graphic card that supports shadowplay.
You might want to try out the free-to-play client of Rise Of Flight some time. It's a WW1 flight sim that offers a really good record-and-replay function. You can hit a key for starting/stopping recording any time during flight and view the recording afterwards using all kinds of camera positions and angles. And since the states you mention to be recorded consist of merely a bunch of coordinates and vectors, it's by far not as taxing on your machine as many seem to think it would be. I know, I'm using it myself very often when going on a flight, because it helps analyse your maneuvering to "git gud".
Being as sophisticated as it is, Rise of Flight's record/replay function leads to a huge number of player-made trailers on Youtube which are of high quality very often. The developers make ample use of that fact by occassionally organising trailer contests for some item from their store.
ED, as many sims and sim-likes nowadays, relies on consumer's word-of-mouth promotion for a large part, and ED especially, since FD aren't exactly hyperactive in their marketing, with all due respect. Good screenshots are an important aspect of that, and I'm afraid the fact that FD has treated the matter of external views so lackadaisically may have hurt sales to a certain extent. But we're getting that now, so we'll be fine in that regard.
A replay mechanic, however, would push sales more noticeably than mere screenshots ever could - at no further cost to FD beyond the initial implementation. Rise of Flight is a testament to that. It's a proper WW1 flight sim: It's in the niche of a niche, and yet it thrives!

Actually no, not really.
[Edit:] Oh yeah, here's a link to the
download of Rise of Flight's f2p client for your convenience. Seriously, try it out for yourself.
You too, FD!
