I would like to upgrade some old videos I made long ago using standard definition (or lower) video sources, replacing them with higher definition sources, but without access to the original project files.
For example, it could be a fan-made music video with video sourced from an old film on DVD, but now I have the blu-ray and I want to automatically find and replace all the matched content from the edited video.
To do this I need a library or script for windows that will take two videos, compare one to the other finding all the similarities and reports a list of timecodes where the 2 videos appear to match.
With such a tool I could easily automate this process completely.
I'm sure such a script (open-source) already exists, I just can't find it. Can someone point me in the right direction?
