Back in 1999-2000, I created some After Effects animations which were output into Media 100. (If I am not mistaken, Media 100 converted my original Quicktime files into Media 100 files.)
Long story short, today I have some important animation files that my home system can't see. In the past, I thought I had the correct codec that allowed me to use these files. Somewhere along the update process, this codec was unknowingly removed or deleted.
Here is the format of a typical video clip name, if this provides any additional clues:
I want to import these files into After Effects (preferrably) where I can re-render them (uncompressed) as Quicktime movies, so I can show them to a client.
