Hey thanks for the potential solution. Bare with me - like I said I am 100% new to AE. First of all - I was able to figure out that the original issue was a problem with the way that I was importing the file. I think the names of my raw files were way too long, because I batch changed the name and now I actually have a movie in front of me that I can play, and click and drag through, etc. Unfortunately, now it is so impossibly slow that I can't do anything. Slow as in I hit play and wait 10 seconds, and the clip moves the tiniest bit, wait 10 more seconds and it moves the tiniest bit again. So your suggestion definitely still seems just as valid as it did before and I like the idea of creating the proxy, it makes sense. But I'm either not doing something right or it's not working. I did the steps you suggested, created the proxy, but it didn't seem to make any difference whatsoever. (File, Create Proxy, Movie). I did it off of the sequence, I now see a second composition (Comp 2), but same degree of slowness. I also don't see any checkbox to the left like you indicated in your photo.
