Jitter Video Scaling

Hey, I’m a new Jitter user, and I’m having some trouble scaling my videos correctly. I’m using 640 X 480 .mov files. Jitter seems to crop them slightly: I’m rendering the videos onto a videoplane and the only way I can get them to accurately fit into my window is to offset them by .4 on the z axis with the position message. Unfortunately, when I fullscreen, I’m left with a video bordered by the grey strips of the gl universe. Any advice?

Thanks in advance…

Videoplane can be a bit tricky. I would mess with the @scale attribute instead of the z position. You can also set your erase_color to black ( something like erase_color 0. 0. 0. 0) to at least not have grey sides.

You’ll mostly be messing with your x scale…but if you’re fullscreening on a laptop monitor, chances are it’s not the same 4:3 aspect ratio as your 640×480 movie so something needs to be either cropped or stretched

here’s a thread about non-intuitive videoplane scaling:

I think the best and easiest way to do is to set the videoplane attribute to "@transform_reset 2". It helped a lot for me.
