That Dead Space trailer has always been a very favorite of mine, just the execution was brilliant and creepy all in one. So I believe something like the Dead Space trailer too would be awesome. I also like the Doom 3 trailer as well, since it is very straight to the point. So maybe a combination of the two? I think in terms of how to make this trailer attract people to the game when they watch it, we definitely should include cleverness, and maybe not even any dialogue except which is in game. That is just a suggestion on my part, I am completely open to ideas and any suggestions you guys got. I do prefer the Dead Space because of its execution, which is great. The Doom 3 trailer is a great as well, but maybe a little too much to the point with the narrator. Other than that though, both trailers are cool, and would be great in a SCP Format haha. I see your point on putting a heavy emphasis on in game footage, I like the idea too. I also like the idea of using animated footage as well. Such as Omniary suggested about exporting SCP/NPC's and a map to a 4D Cinema format or Maya format. I would love that, my experience with 4D Cinema and Maya come from creating Special Effects to include in some of my short films. Such as 3D Animated Jets and Spaceships and so on. I have never really attempted full on animated scenes before though. It would be a great challenge, but in terms of making this trailer the best it can, and after seeing many of the things you guys have come up with in terms of animating models and so on, I definitely think it would be a good idea if someone who has animated models in this game and knows how the characters move and how they should move according to the SCP universe, I think it would be a great way to include you guys, I have been trying to work on my animation skill set in terms of humanoids, but I mainly have animated (not much) vehicles/automobiles. I can see WAY more talented people in terms of animating and all that on the forums here where you guys collaborate at times, and I think it would be great to have some of those people be included if they would like to of course. Also, the format mostly widely supported by 4D Cinema is .c4d, but models can be in obj. maya. as well, I just can't use any models that reference to 3DS Max, since I do not own that program...yet.
Also DjSaturn, what place? I have been hassled by the cops more than once while filming, that's kind of a downfall to making short films haha, it is worth it though.
