And just a small little rant... these films were made at academy standard 24 fps. I can understand working with PAL 25 fps or NTSC 30 fps, but it really messes with trying to line up different versions when you use a non-standard frame rate. I've found some strange ones. And when you render from one to the other, it can add or subtract frames. I was really pleased to find the JSC collection at 30i fps, which was easy to re-render as 24 fps. And PAL 25fps is a piece of cake to convert to 24 fps. But some are impossible because the actual scenes don't line up due to extra or missing frames. 24 fps is ether true 24 fps (for cinema) or 23.976 fps (for home video).

Convert everything to image sequences (.DPX, TIFF etc.) before you begin, then there are no frame rate issues to begin with.

Various versions are missing frames, particularly around reel changes.
