How can you put a mask around a video that makes it look like 8mm?
hi there
Basically I have shot some 8mm from a projector and kept some black around it so you get the rough edges with it, however I have some other 8mm footage that has no black border or rough edges, I was just wondering is there anyway I can use the existing black rough edges on the other footage and use it on the other footage that doesnt? Like as a track matte or something?
Cheers!

obviously you could use a mask. But if you want something more articulated, I’d create a matte in PS using a brush. You could use a sample frame from your other 8mm footage and draw a greyscale image to match. You could try crushing the levels and what not to your 8mm footage, but you’ll also kill the subtleties with it.
So I’d hand draw a matte (using the other footage to trace over). Then use this matte as a Luma Track matte in AE.

Is the black border, surrouding a just white, like the leader? It would be easy to make a inverted track matte that way.
If not, it will take a little work but you will need to isolate the black borders. My recipe for doing that is to invert the border color channel so they are white. Apply Knoll unmult to it(used to be a free download, but not sure where to get it now). Then apply adjust levels, switch to alpha, and tweak to preference.
Apply this over a black solid and you should have your borders.
Cheers.

Bryans post brings up a great point. Is the black area from the projector or from the film itself? If it is just from the projector characteristics, then just capture a frame of it without film in it what-so-ever. So you do have damn near a perfect matte. That can use just minor levels to get your full range.

Hey so I just found a frame where it was white with the black border and applied it as a luma matte to the layer and it seems to have worked a treat. Excellent, a bit of logic from this forum goes a long way 😉
Actually can I ask…now I have made this video with borders, should I render out as a video and then reimport OR precompose it and use it? Does having the luma matte slow it down much?Thanks!

Oh also what I meant to say was…I have enabled time remapping on the border layer so as to have about 1 second of flickering that repeats itself…does having time remapping enabled slow it down much when Im putting it into future compositions? Or is there any easier way to loop the one second?
thanks
