URGENT – We are working on a Music Video at the moment. The original footage was shot on 35mm movie in a motion control studio…. and now we are matching things up… Ive managed to bring the motion control data into 3DS fine – but am having trouble with the lenses… Lenses used (35mm film) were: 24mm 28mm 35mm 50mm what are the corresponding 3DS lenses I should use? The original film is being tele-cine'd to Digibeta as we speak… THANKS LOTS! Peter B

>>urgent, camera lens… For any calculations using the 3DS camera, use the FOV angle, measured horizontally for the desired rendered resolution. To correlate with a standard camera lens, you'd have to calculate the equivalent FOV. We went through something like this in '93 at work and discussed it somewhat on this forum then. I took the liberty of EMAILing a zipped copy of that discussion to you just now in case it might help. Good luck! JKJ

Thanks very much! I'm sure we will sort it out! Regards, Peter
