I have an animated model shot that was shot and lit as a daylight piece. Its not possible to re-shoot as the model is not available anymore.
I have the task of making this zoom in to a house look like its moonlit and even worse, like there is snow on the ground!
I also have very little time to get this done.
Any suggestions how i might be able to tackle this little challenge?
same like my problem.
what i can suggest is have 16bit footage. try it with a lookup curve. there you can handle nearly every grew value. but keep the curves smooth. otherwise you have burnouts.
maybe this helps you a bit.

the image file i have is pretty good - i got it digitized in adrenaline at 1:1 then exported out as Animation - files look good as it was originally shot on super 16 and has been colour corrected and stabilised when it was used originally.
I shall try the curves - thanks

sound ok about the compression. B U T, animation can
It was shot in 16mm, so it's probably for tv or low budget movie. They aren't going to pay to get it scanned.
If they captured it at 10 bit on the adrenaline then get them to re-output 16 bit sgi or png files. I'm guessing they had it transfered to HD. If they don't know if it's 8 bit or 10 bit, find out if you recieved it on D5(10 bit) or HDCAM(8 bit).

Unfortunately Deke, its not that auspicious. I did the digitizing myself. Source is on Beta SP. The project is to utilize and recycle as much as i can for use in a promo to sell a concept to our companies new owners!
I have no budget, as this is an emergency!
all sounds very dramatic, but its really a last ditch rush!!
i don't think the snow effect is going to be a problem. I have rotoshaped out a roof and used a white background to provide snow. A darker colour will be used for the slopes away from the moonlight.
I am getting puzzled by one thing though. I have created trackers for each of the eleven corners of the roof shape, and each one corresponds to a matching control point on the rotoshape. I have used the attach tracker button to select the appropriate track. But i cannot get the rotoshape to move with the trackpoints.
They do move, but its not doing what i would expect.
I have RTFM but found that just adds to the confusion.
I could manually alter the roto control points for every frame, but the tracker is more accurate - so what am i doing wrong?
In shake 4 you should just be able to right-click on the knot and attach it to the tracker you want. If you are still having problems maybe try re-tracking?
thats correct, jjasper. But what i want to happen does not happen. yes the point attaches to the tracker and moves, it does not deform the roto.
Imagine this scenario - i have a camera dollying around a model shot which contains several buildings. It moves in an arc,swinging around whilst tracking in towards one house. I create a rotoshape to cover the roof area at frame 1. By the time it has moved a few frames, the geometry/size of the roto needs to change to reflect the change in roof geometry.
The tracker points are positioned in exactly the same place as the roto points are, and the roto is made using linear lines - no curves at all. Each tracker is connected to its respective roto point. The trackers are all accurate ( i have been through frame by frame checking them). When i render a flipbook (or just move through the timeline) the roto follows the direction of the trackers but tends to follow exactly to just one point....so the roto keeps its initial shape and just tags itself to one tracker. The roto does not enlarge or expand or alter its shape in any way.
I have a feeling the limit of the roto/tracking options is a four point track and a corner pinning node. I think i maybe asking more of shake than its capable of. pity really!!
I haven't used the new point tracking for the roto nodes yet. Here are a few ways I would have done this before this "feature".
take 4 track point from the roof and put them in a stabilize node, make the roto for the frame that has the most amount of roof in the shot with the least amount of distortion(ie, as strait on of a frame as you can find). Attach that roto to the stabilize and set the "ref frame" to that frame you roto'd for. The roto should deform and with the stabilize node pretty well pending you have good tracks. Also if you have any barrel distortion in the shot, make sure you track and do your comp on an undistorted plate.
Similar to above, but track in a 3d tracker. This gives perfect tracks(much better then 2d because it is less effected by stuff like grain and light slight light shifts like a blinking light), just pick 4 points at the farthest reaches of the roof top and export that to shake as a Stabilize node. The follow the rest of #1.
Much more archaic. Sam Cole has posted a few times on the listserve how to attach trackers to a quickshape. Little bit of text mashing.
