Hello -
I'm digitizing old 8mm and Super 8mm film. For reasons outside the scope of this question, I'm doing it the cheap-o way, where I project the film onto a screen, and capture that with a digital video camera.
The digital video I record has several issues, the first of which is that it's not cropped correctly. As you can imagine, projected film doesn't have a nice sharp border, and the edges are a bit fuzzy. I've done my best when recording the video to center the image, but I still need to crop, center, and zoom the image.
I've got a variety of other issues that need to be fixed too, like deflicker (due to the 18fps projector gate flicker), and color correction. The builtin deflicker filter works very nicely, and color correction seems straight forward enough. I think I'll use temporal NR and spatial NR to clean the image up a bit, and maybe sharpen it after that. I'm thinking about using the dirt removal filter too, but still experimenting.
I've tried cropping the video by:
- Going to the Edit screen
- Looking in the Inspector pane
- Enabling Cropping, and adjusting the dimensions accordingly
However, this alone does not seem to do what I want. While I do see a nice crisp black border around my cropped video, it's not centering the video, and not zooming/ scaling to fill the frame.
How do I center and zoom the cropped video?
Also, do I need to concern myself with maintaining aspect ratio? I'm OK with black bars on the sides, but I'm not sure what the "right way" to output the video would be. I'd assume it'd be to crop to actual dimensions, and leave scaling and adding black bars up to the device doing playback.
