I think its Avid Express, version 1.5... not sure, saw the thing first time 2 days ago

and me and my class are going to make a short film without any knowledge how to do it
When I asked a few of the 2nd year kids they told me it just takes gaddamn too long to export the video from avid to a file, edit it in after effects and then render there and then back to avid and then put it together. But I just find that the after effects is just like billion times better (saw that the first time the same day

) than avid when putting video together, like their timeline part is sooo much better. One thing I can say about avid, ITS FAST, I was so surprised
One crazy Idea I had, is it possible to export the movie to tiff images, as in one frame one image, then create a batch in photoshop that edits all the images like we want to, then convert all the tiff images back to a movie stream?
also, for about a 10 minute movie, then how long would it take to render it going the avid/ae/avid way?
