So here’s my challenge.
I have a regular 4:3 video that I’d like to convert to a 16:9. Just cropping top and bottom of the frame would work, but the results in some shots would not be ideal.
I was thinking of a sequence plugin that would allow the user to position a 16:9 frame on the 4:3 video image and copy that video to the output buffer. Of course it would be fully controllable by IPO, allowing the framing to follow the subject say as they move from top to bottom of the frame.
From reading the sequence plugin documentation, it looks like the input and output buffers must be the same size. That could be worked around say by copying the target frame onto a letterboxed 4:3 template. Or even resizing the image to make an anamorphic 16:9 filling a 4:3 frame.
Has anyone seen a plugin like this for blender? Would this be a good approach? Is there a better way to do this in Blender? Or can someone suggest another 3rd party tool that cold do this? (I’m sure avisynth could, but I’d need something to generate the offset for the framing for each frame of video).
