300 Zoom In Effect
Not sure if this is the proper forum, but for the life of me I’ve been trying to figure out how they did this:

Sorry its at 2 minutes, 59 seconds. Seen it in commercials too.
My first guess is they optically zoomed in, and use some sort of cuts mixed with a post production technique. Its just so smooth.
Second guess is its a digital zoom/crop, since its green screen I’m assuming you could just pop it up like that, but there’s so much detail…
Thanks fellas.

I would guess its a real zoom out that blends in with a cg zoom out. They probably did a 3d track on the camera and then matched the camera in CG, then when you get far enough away they switch to the CG.

Imagine 2 layers each shot separately against green screen:
Layer one: The hero guy runs towards camera
Layer two: A group of 20 guys side by side run towards camera.Key out the green screen make 100 copies of Layer two set each one a little further back in “Z” space — Move layer one (Hero Guy a little closer than all the others in “Z” space — now we can use the camera in After Effects’ using: zoom + Depth of Field to zoom in on our hero’s layer and focus on him — throwing all the other layers into blurry perfection….
That’s my guess on how I’d try to do this anyway…

I believe they mention this in the commentary for this movie – and I think I also heard this from some FX podcast, but what I believe that they did for this and an earlier scene with similar zooms was to get three cameras mounted on the same piece of hardware and shoot the scene/camera move simultaneously with all three at multiple levels of zoom. Then, in post, they digitally transitioned between these wide-mid-close shots.
I’d recommend the DVD, btw. Zack Snyder does the commentary, and it’s got some pretty good stuff in it.
