Cinemascope vs. Square vs. Correct Pixel Aspect Ratio for 5126x2160

[Carlos_Gonzalez]

Hello Everyone,

I am new to the forum but I am currently working on grading my first Indie Film in Davinci Resolve. I am setting up my timeline for 2k 2048x1156 (pixel aspect ratio Cinemascope). Is this the correct aspect for a film shot mostly in the 5120x2160. This was not shot with anamorphic lenses. What would be the proper workflow. The client didn't really have a target output so I went with the 2k FIlm. They know they will go DVD and other formats but they don't think they will be going Theatrical release. But they wanted to grade in 2k. Is my workflow correct. I set the timeline as stated above. In the browser i set my r3d clips from square to cinemascope. I also setup the input scaling to stretch frame to all corners. Please if anyone has better suggestions for this project I am all ears. I am afraid that this workflow could be distorting the original image. I am only on the first reel so I can change these settings. I just want to be 100% sure.

thanks

If you have shot with a normal lens you should leave the PAR in square and set the Timeline Res to the aspect ratio and res you are aiming for with the release. If you aim is DCP 2K scope this would be 2048x858 so it doesn't sound like this is where you were heading. Try regular DCI 2K, 2048x1080 for the timeline res and adjust that for each render as you need. In Resolve all the PowerWindows automatically move to the correct position when you change res.

Thanks Peter for your response. I definitely was changing the ratio to a wrong setting I set it back to square. Picture is back to normal. Project is back on track.
