one character doubles...

I'm trying to get this...
a character is walking away from the camera, suddenly he stops and turns back while at the same time we still have the other layer in which he is still walking away.
any suggestions?
 
Shoot it twice. Once, where he keeps moving, once where he turns. Then blend the two together at the right time.
 
Make sure you keep the camera locked in one position unless you have motion control capabilities.

I would also suggest leaving the camera rolling in between takes to cut down on the risk of nudging the camera when you start and stop the recording.
 
yeah, thanks...I was going to do it that way but I thought the results won't be satisfying, cause finding the exact right spot and gesture of doubling is nearly impossible...
I really don't want the blurry thing happen at the doubling time, though with a touch of this and that it won't be that bad...I hope!
 
well, I shoot some tests and the problems began...

to make it easier I changed the script so the person who gets doubled is sitting motionless...
I thought of doubling the layer, freezing one and bringing down the transparency of the above layer...but that darkens the shot...so the only way to do this is to mask the guy as he's standing up frame by frame...
it seems dumb, there should be a better way...
 
Try a difference matte. If the shots match, it should remove everything that is the same in the two layers.
 
If the overlay darkens the shot, then adjust the brightness/contrast of just that piece with the overlay, until it matches the rest of the footage.
 
Wait a second here. Come to think of it, you must be doing something wrong, cause it should be possible to simply overlay the two. What compositing software are you using?
 
I'm using AE7...
I don't think so...it should be like that...a 50% transparent layer should darken the layer below...I used all blending modes but nothing changes...
But you're right, I myself think I'm doing something wrong, and I guess it's so simple that it has muddled my thoughts...
 
the problem is in some blending modes the overall image doesn't change but the guy in the under-layer gets transparent...and in some modes vice versa...

well, forget what I'm asking, try to think of all those films in which the ghost of a person parts from the body...it's a classic, why all these problems...?!

and I'm unexperienced...my knowledge is mostly theoretical, I understand what you're saying but my hands are a bit tied!
 
Two identical layers on top of each other, will not darken, unless you're using a special blending mode. You should just use normal.
 
two overlapping layers, the top one at 50%, should work fine if you want both versions of the person to appear as 50% 'ghosts'. But if you want them both to appear 'solid' (but one in front of the other), then some sort of keying/masking will be needed

Yes, that's it...I wanted one transparent and one solid...and earlier in this thread I mentioned the need of masking, but it still seems dumb...why for an effect that could be done (or should be done!) with a mixture of two kinds of layer blending, I should go for a frustrating process of frame-by-frame masking with a poor result...!

it makes no sense to me...but seems that's the only way, thanks guys...
 
I tried it in Premiere Pro 1.5. It doesn't work all that well.

yeah, what 12quidkidinnitt has done is fine if you want both layers to 'ghost' - and it sure is the easiest option! - but it's no good if you really need the underlayer to look 'solid', which is what i think you're wanting.

If it was me, I'd shoot both people layers against greenscreen plus a background layer, that way the 'back' person can stay 'solid'. But greenscreen may bring a whole new bunch of problems, depending on your location and lighting
