Not sure if I'm too late here, but I think what you were asking for is the Aspect Ratio of 35mm film. Aspect Ratio's of many popular Outputs are as follows: Movies: 16:9... the great surprise to many is that the movies that we see at the theatres is NOT 16:9. Instead there are a number of ratios, 1.33:1 (or, 4:3,) 1.5:1 (the most common,) 1.66:1, 1.85:1 and 2.35:1 are common sizes Bryce 5 - 70mm resoulution is 6144x2048 or 3:2 , Vistavision, Cine35. 35mm Film 3072x2048 (1.5:1,) TV NTSC D1 video is 720x486 (1.48:1,) while PAL/SECAM D1 video is 720x576 (1.25:1). You'll notice that there isn't a 4:3 ratio among the video resolutions. Whut up wit dat!? Since there is a certain area lost to the bezel around the tv, and also TV's squeeze the image horizontally by 10-11%. You'll need to contact who actually doing the tansfer. Ask them what the minimum and maximum resolutions they can transfer to thier 35mm. Also why are you trying to put video onto a Still frame negative. Is there a 35mm video film? I thought 35mm was jsut for cameras. = )
