Hi, I just need to get the color of the top-left pixel in a movie at different times so I can run it through a chroma keyer. I know this is probably really simple, but I can't figure it out. Thanks.

send the getcell 0 0 message to a matrix object.

if you output the movie into a matrix, then you can use the [getcell 0 0] message on that matrix to extract the pixelinfo.

but reading the tutorials and docs will help more.
