I hope it is not too late, but I'm pretty sure Photoshop can be automated to take all tiff's in a folder and convert them to whatever other format Photoshop supports.
I use ImageMagick to do things like that, it's remarkably lightweight (nowhere near the disk space required for photochop), but still very powerful. And not that you asked, but after I've built all my image frames from the data, I stitch them together into .mp4's with ffmpeg. Video data products are so obviously the future, but don't tell all the old men who still get printed journals delivered to physical mailboxes.
It's so too late, dude. Apple rewrote them. And when I looked at my time machine backups on Apple, it rewrote those, too. Theoretically I could have attempted to mount time machine stripes on my Windows machine and hope for the best but the act of looking for them in OS X destroyed anything that wasn't destroyed.
