Hasta La Motion!

1.I am looking for 3d multipass render footage including mattes for practise. I am learning multipass compositing. However i havent been able to come across

much footage for practise.

2. Also, I have queries about the ID mattes or the matte with RGB color. The queries are
a. why do we need them?
b. how do we use them while compositing?
c. how are they generated?

If you have any link to the footage or footage of your own kindly help me. It is purely for practise purpose.
Any link to tutorial or knowledge resource about ID mattes are also welcomed.

Thanks & Regards

Nuke wants to only put those clips on the timeline at the DPX sequences timecode? How can I push these clips so even though their fame number or timecode is a certain sequence say 15000-150100. They are at my timelines frame 1-100?? If I change the "frame range" on the read node, to say 1 – 100 it says the frames aren’t there, because it thinks the clip wants to start on frame 15000.

How do I do this?? In SHAKE we had an in and out range, even if the frame number or timecode didn’t correlate to that..

Thanks.

Thanks for any tips.
