Rendering An Image Plane As Background

[3dfr3ak]

Hello, im having this problem: I get an image plane from a sequence for a perspective camera to use as background, when I render, the image is cropped by the sides compared to the original; after I change the film resolution gate to horizontal, the image renders complete but squashed. The render resolution is the same as the original sequence. I dont know what else to do, I need the background mainly as a reference to acomodate a character, the final render wont have any background, but if it doesnt match the same size and shape of the original sequence...

Any help is apreciated, thanks in advance.

You need not only the same render resolution, but also the same pixel aspect ratio. Possibly your footage has an aspect ratio of 0.9 (NTSC) or 1.066 (PAL). Your default maya scene will have an aspect ratio of 1.0 (square pixels). Since the monitor has square pixels, displaying non-square footage on a computer monitor will generally squash. If you set the Maya Render Settings to the same pixel aspect as your footage your final composite should work fine.

thank you very much, it worked!

I also fited to size and used fit to film gate (placement section) I dont know if the second option replaced the first, but now the background looks the same as the original footage.
