If you generate frames one at time (i.e. 3d rendering) -- you might have missing frames in your sequences used in After Effects. Beware because CS6 makes this a massive headache. If someone knows a workaround besides a huge time-waster that is creating dummy filler frames, please let me know. Please submit a bug report to Adobe because this missing frames warning is a massive frustration... Feel free to copy/paste from below.
******BUG******
Concise problem statement:
The missing frames warning indicator IS HORRIBLE. It is intrusive, unnecessary and inefficient.
Steps to reproduce bug:
1. I Have loaded a series of sequential frames. They are coming from a 3d renderer so sometimes frames are missing and are filling in gradually.
2. Add the sequential frames to a composition
3. Scrub the playhead in the composition.
Results: Each time I touch the scrub bar, I get a warning "After Effects warning: The sequence has 335 missing frames." Next time I touch the scrub bar "The sequence has 334 missing frames"
Expected results: Pre CS6 -- The missing frames warning used to come up ONCE when reloading or loading footage... NOT EVERY time I touched the scrub bar. It is SO annoying. Make it work the way it used to in CS5. This current implementation is absolutely horrendous. It is completely useless and a huge waste of time for people who generate individual frames (i.e. 3d animators -- many of whom use After Effects)
I thought CS5.5 brought new missing frame behavior. IIRC, it automatically filled in gaps as they were being rendered. So you could bring in an incomplete image sequence while you were rendering in 3D, and AE would automatically (and silently) fill in the gaps as the frames became available.
Is this not the case for CS6?
I skipped 5.5 so I don't know how it worked.
The problem is not that AE CS6 automatically fills in the frames as they become available -- the problem is that it incessantly pops up warning dialogs when you scrub the time slider and the number of missing frames changes (as happens continually when rendering them out from 3d). We don't need repeated warnings like this. CS5 did not do this at all.
Adobe is obviously very responsive to their customers. It's only been about 3 months. For super-annoying features, I think they promise an 18-month turnaround.
I requested auto-save for Illustrator about 10 years ago. Still waiting for that one....
Use feature request -- I already did ... but more voices have a slightly better chance of being heard.

i can't believe this has gone unresolved all this time.
so much for doing a full screen ram preview of a partial sequence. also, every time a frame is added, it completely tosses out all the frames that existed in ram preview.
but by all means adobe, keep devoting your resources to gee whiz crap like rotobrush, so that you can make nice demos of your software that is nothing but frustration in real-world workflows.
I've used AE for real world workflow since AE belonged to COSA...
Make sure your configured correctly. Make sure that you're not trying to preview something that is too big and too high rez for your system.
Make sure that your MP settings are in line with your system and the effects used.
If all else fails turn off disk cache.
