View Full Version : Film Back Setting

I can't find any information on getting around LW's lack of a film back setting for cameras.

I have a live plate green screen, shot at 1920x1080 on a camera with a 9mm lens and film back of 9.6mm x 5.4mm.

However, if I choose 1920x1080 and a 9mm lens with a LW camera, it doesn't match, presumably because the film back is wrong. I can do an instant match in Modo using the figures from the shoot, as Modo has a film back setting - I therefore know the figures are correct.

The question is - how do I effectively adjust the film back on a LW camera, without having the specific option available to any of the cameras?

Thanks in advance.

Would it not be adjusted in the "frame" setting in the camera properties? I've never adjusted it personally but it would seem to be the same thing...of course you'd have to convert the size into an aspect ratio as Lightwave is backwards like that.

"Frame" is the film height. The width is calculated based on the frame aspect ratio.

ah ok...I never have understood how to use that properly.
