L K Keerthi Basu Posted August 29, 2015 Share Posted August 29, 2015 Dear friends, My short film Director is very much interested to shoot his short film in 1.33:1 ratio. We are planning to shoot in Red Dragon, some of my friends came up with a doubt that 4:3 and 1.33:1 are not the same aspect ratio and there will be a project issue will be there. Please clarify my doubt i can't able to sleep. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted August 29, 2015 Premium Member Share Posted August 29, 2015 This is just basic math, not cinematography. 4:3 and 1.33:1 are the same ratio of width to height, just divide 4 by 3 and you get 1.333333.... so it's the same ratio just expressed differently, 4:3 expresses it in whole numbers, 1.33 : 1 expresses it by keeping the vertical at a value of "1" and letting the horizontal not be a whole number. This is a holdover from video versus film -- video aspect ratios are expressed in whole numbers (4:3, 16:9) and film aspect ratios are expressed with the vertical as a single unit, so 1.33 : 1, 1.85 : 1, etc. Projection issues are a whole other thing though, you'd have to figure out how you were going to screen a 1.33 : 1 image -- probably with black borders on the sides of a 16:9 HD file or a 2K DCP. Or you'd be making a transfer to 35mm for projection on a print, but if you have sound on the print, the actual projection aspect ratio would be 1.37 : 1 Academy and you'd have to make sure your theater could screen the Academy print format, otherwise you may have to transfer the 1.33 : 1 image with a windowbox within 1.85 : 1 print area so that a theater set-up to project only 1.85 flat or 2.40 scope could show it properly.

L K Keerthi Basu Posted August 30, 2015 Author Share Posted August 30, 2015 Thank you David, my final projection format is going to be both in 16:9 HD and 2K DCP. Link to comment Share on other sites More sharing options...
