I have created an architectural model in *someone else's* software, and animated a camera in *someone else's* software, and rendered that out to still images. I rendered every 5th frame (for a total of 401 frames) in order to save time on rendering. My goal is to create a short movie (2 minutes) of the camera flying around the building.
When I imported all of the images, I stretched the duration so that they equally fit the 2 minutes, and used the keyframe assistant to sequence the layers. Now that I've done that, the movie is choppy (as I expected it to be, since I only rendered every 5th frame). Does anyone have suggestions as to what effect or transition can be used to smooth the sequence out? Or am I living in a dreamland and I need to go back and render every single frame? Is this even the software I should be using? I'm obviously a n00b, so any help is greatly appreciated.

You should go back and just rerender all of the frames.

You need to install the updates. Choose Help > Updates. There have been three major bug-fix updates for your version.

You are. There is no effect that could automatically synthesize those missing frames even halfway realistically. Timewarp and Twixtor are only gonna make things look like a smear even with a lot of tweaking. By the time you have tweaked their settings and done all your masking and otehr corrections, your 3D render with all frames will be finished just as well and offer better quality.
