I saw the original a couple of years ago. Along with it the have the digital copy that you can scan through and zoom in on.
That’s AMAZING!
The copy I’m working from was 39,974x1600 to fit in 1280x720. The file was too big to be taken into EITHER Photoshop OR Adobe Premiere. The only way to keep a continuous move was to divide the file in half, exactly match the two pieces in the middle of the music TO THE PIXEL, and use a pause to make the move across the two pieces. That took awhile.
