We'll already have digital doubles, as we will be using them in a few other shots.... The other plan would be to shoot them still, and add the movement and motion-blur in post - I think that might well be the best solution. As for what we're shooting on - at the moment, it's looking like it's going to be HDV (ouch) - although, budget depending, we may be using HDCAM for the VFX shots, and then degrading it to look like HDV after doing the VFX....

That way you will resolve the parallax issues. In terms of getting a clean key...I don't know which camera are you using but for that amount of motion blur you need something with 4:4:4 colour space... If you're stuck with a mini-dv (hope you're not) then you can try getting your footage into YUV colour space and blurring the U and V channel by 15-25% and then converting back to RGB. That should help you get rid off jagged edges... I'ts really hard to tell how much detail on the actors will be visible...would you consider using primitive cg stand-ins ? You could make them in matter of a day-two and save yourself a lot of keying time + it's kinda easier to match the lighting in 3D...and also you could use them for some more similar shots. good luck, CroVFX After studying your previz and the camera movement on it , personally I think that you should find a similar background and

Because this shot starts off looking like a straight opening shot of the city, I'd like to make it more than just a static shot.

I know it's not the sam but it's quite easy to make it look almost completely the same...and a lot cheaper while we're at it :D I think that if you have a locked of shot of a person on greenscreen who is in place and if you then animate the shot to make it seem like he's moving...I believe it would be a simple and believable fake. You don't want to go with keying that much motion blur... If you do shoot it in motion, keep the shutter closed up as much as humanly possible, so you'll have as little motion blur as you can, and then you fake the blur. It will make your job a lot easier. I know how it is with keying blurred footage and I can agree that it is absolutely horrible :D Why wouldn’t you use a still of the background and pan it to make it feel like it was a crane shot?
