Shashank P Walia Posted November 29, 2022 Share Posted November 29, 2022 Hello All, Greetings. What would be the best way to master a 2:1 output from 2:35 :1 frame. If we are filming with Red Komodo in 6K 4:3 with 2X i.e 4320 x 3240 (de-squeezed 8640 x 3240). Also keeping in mind if we are using a 2x lens. How much of a resolution loss would be there Regards, Shashank Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted November 29, 2022 Premium Member Share Posted November 29, 2022 First of all keep in mind that your initial resolution is 4320 x 3240 -- the resizing to take out the squeeze doesn't add resolution. So in theory, if your image has a 2X squeeze and you want to create a 2:1 image, then your max resolution comes from a square area of the sensor, so the max resolution from your recording is 3240 x 3240. Now how you get to an unsqueezed 2:1 frame from that sensor area is up to you, it depends on your delivery format: 4K DCP with 2:1 inside 1.85 (black borders top & bottom)? Inside 2.39 (black borders on each side)? 16x9 UHD video (3840 x 2160) with a 2:1 letterbox? Either way, your resolution limit is 3240 x 3240. So I guess you would start by cropping and unsqueezing to 6480 x 3240. But then whether you master for a theatrical 4K DCP first, then 3.8K UHD from that, depends on your delivery requirements. Cinema 4K DCPAspect Ratio / Resolution Flat (1.85) / 3996 x 2160 Scope (2.39) / 4096 x 1716 Full Container (1.90) / 4096 x 2160 I assume "full container" is used for digital IMAX releases but I'm not sure you'd be guaranteed of that so I'd probably work within the 1.85 or 2.39 containers.
