Here is my workflow. You guys tell me if I am doing anything wrong (most probably I am).
1. I use a Canon EOS-M camera with Magic Lantern Crop Mood installed and shoot a clip in 4.8K, 2.35:1 anamorphic.
2. I then use the MLV app to export the .MLV file to AppleProRes LT for the sole purpose of finding out what the final de-squeezed size should be. It turns out that the final size must be 4800x2040 pixels. I write this down.
3. I then use the MLV app again to export the same .MLV clip to CinemaDNG Lossless.
4. I create a new project in DaVinci Resolve.
5. I change the project settings (File > Project setings) to Custom and then enter 4800x2040 pixels
6. Then I import the CinemaDNG sequence in the Media Pool of DaVinci Resolve
7. In the Cut page I drag the CinemaDNG sequence down to the editor tab, and this automatically creates a new Timeline
8. I right click on the new Timeline and do Timeline Settings > uncheck Use Project Settings > Mismateched Resolution = Stretch frame to all corners
Tada! I now have a perfectly de-squeezed footage.
Now. I see one huge problem with this workflow.
The original CinemaDNG's are 1020 pixels tall, which means that when I stretch them to the final height of 2040 pixels, I lose quality.
If I leave them at 1020 pixels of height, then I no longer have 4.8K footage. It is a Catch 22 situation.
What should I change in this workflow?
How do you guys manage to upscale the 1020 pixel DNGs to a larger size without loss of quality?
