Maya Camera Import – Unit Translation

[Wisorxn]

I think it all has to do with aspect ratios. The key is to match the rendered footage aspect ratio with that of the camera’s Film Aspect Ratio attribute. By default, maya sets it’s render globals aspect ratio to 1.333:1, when you make a new camera, the aspect ratio is at 1.5:1. Therefore when it is rendered, the footage is at 1.333. When you export the camera information/nulls, the camera is looking at the film through 1.5 aspect ratio, no good. The answer is to set these two equal to each other by either changing the numberical value in the render globals and the camera aspect ratio, or by using the Fit Resolution Gate attribute for the camera to either horizontal or vertical.

Also, in AE, I changed my import default to 24fps (as that is what I have in maya). Before my rendered frames were coming in at 30fps, whereas the camera is at 24fps from maya, another matchup issue. Now my rendered frames and camera/null info are matching correctly. Hope this helps!

first i need to say: i dont know what i did wrong yesterday, but everything works perfect today…

i think it has to do with the aspect ratio of the film back, too. if the AR is at the default 1:1,5 and your resolution is set to 400*300 1:1,33 – maya uses only a portion of the filmback. its like 35mm film. depending on the format you use, different portions of your filmback will be exposed. but you need to be aware that if you dont have same AR not to use “Fit Resolution Gate: Fill” for the cam. “Fill” only works if you got same AR.

but im wondering because “horizontal” is the default here with maya 8.
