Hasta La Motion!

First of all, I did some graphics in photoshop (some sort of flowers) and saved it as a PNG with alpha.
I need to put this on a wall and to reveal the flowers slowly from left to right.
I tried to do it with the paint node by animating a stroke (bigger than the flowers) that affects the alpha channel of the PNG but it doesn’t work since it affects the original alpha, revealing a black background behind the flowers because the stroke is bigger than the graphic itself.
Is there a way to do what I want? I’m sure there is, but I can’t seem to find it!

I also have a problem with the tracker node.
The footage is a side view of a women walking down the street and the camera is following her. I want to track some points on the wall behind her to put my graphics on. Everytime I start the tracking, the point gets lost after a couple frames.
I tried to track a point on the women and it works perfectly, but it doesn’t work on the wall.
I did put my tracking points on bricks corner and stuff like that, but they keep sliding.
I also tried to colorcorrect the footage a little to give it more contrast, thinking it would help tracking but it still doesn’t work.
The footage comes from a Sony HDR-XR550V camera and I desinterlaced the footage.

I hope I made it clear enough. Sorry if it’s not, my english isn’t perfect.

Thanks you so much for your help!

I couldn’t figure this out and am going to use the example below to better describe my question.
When I execute the code below in the script editor, I will get listA = [1, 2, 3] printed and the listA can be referred throughout the current session.

To integrate the code as a python script, I wrap the code as a function as below:

and modify the menu.py so I can execute the python script upon button-pushing.

As I execute the python script, I did get the listA = [1,2,3] printed in the script editor, but if I try to refer to the listA again by executing, say, print listA, I will get:

What I want to achieve is generating a list storing wanted information through the python script so I can refer to over and over again in the same session. Any comment?

Thanks,
Jason

I wan to run these programs, may 2-3 at the same time :

Adobe Photoshop
Adobe Illustrator
3d Max
Maya
After effects
Syflex
VRay
Houdini
Realflow
Renderman

Now I should ideally be looking at this beast :
SYX OVERCLOCKABLE I7 GAMING PC
http://www.circuitcity.com/applicati…4&Sku=SYX-1052

But unfortunately I do not have that kind of money. I do not know how much would it cost to custom make that kind of desktop and who can make it for me in cheap cost. Some imputs regarding that would be appreciated too.

I was looking into these desktops lately :

1) HP Factory Refurbished Pavilion Elite HPE-170T Desktop – 8GB DDR3, 750GB HDD, Core i7-860~3.46GHz Quad-Core WIFI

http://cgi.ebay.com/HP-Factory-Refur…pt=Desktop_PCs

2) HP – Factory-Refurbished Pavilion Desktop / Intel® Core™2 Quad Processor / 7GB Memory / 1TB Hard Drive

http://www.bestbuy.com/site/HP+-+Fac…&skuId=1014586

3) Gateway – Desktop / Intel® Core™ i7 Processor / 8GB Memory / 1TB Hard Drive
http://www.bestbuy.com/site/Gateway+…&skuId=9974337

4) Lenovo – Ideacentre Desktop / Intel® Core™ i7 Processor / 8GB Memory / 1TB Hard Drive
http://www.bestbuy.com/site/Lenovo+-…&skuId=9979887

These are all that I could find … i will add some if i find some later. Please advice me which one would be good within $900 range ( max). Also some advice on the approx. cost and assemblers regarding a specific configuration or for the above SYX OVERCLOCKABLE I7 GAMING PC would be really appreciated. I would be looking for some real helpful feedbacks. Thank you:o

I’m trying to track a shot where some guy holds a green piece of paper with some track marks on it. I’m trying to composite a photo on top of that lil mini-greenscreen (unfortunatly it wasnt possible to have the actor look at the real photo so thats why we had to go with this complicated mess). there’s a bit of movement and a bit of paper bending involved. we’ve been trying for ages to track it in mocha but all we get is a really really shaking track. plus I cant seem to find out how to adjust the photo to the bending that happens when the actor holds the green sheet in his hands.

anyone’s got any idea on how to approach that successfully? THANKS ALOT!

cheers!
