Split your layer at the segments that you want to stabilize, stabilize the split segments only (not the whole darn thing ), then cut back or fade back to your unaltered footage. BTW, this would probably be a better task done via dynamic link with Premiere...
Yes, splitting it is what I initially did... but the transitions weren't really very good, even with some fancy scaling, rotating .. etc. The effect also gave a really nice floating feeling to the bits which weren't shaky, so why not effect the whole thing?
And if I'm going to do the whole thing, why not just do the whole thing? That way any fiddling with the scale, or Stabilization method will be consistent alcross the whole project.
So my question was wether I've exceeded some known threshold in AE (like the 30,000 x 30,000 pixel limit that used to exist... maybe still does?) that prevents this from successfully finishing?
Sure, I'll try breaking things down and applying the same settings to each section in the hopes the analysis will be the same across section breaks... but one analysis is better than 10 I say!
Is there nowhere in the 93 minute movie that you can make a cut. Here's what I'd do. I'd make a comp that was a little bigger than the footage, say 100 pixels. Then I'd stabilize the section that I want to fix choosing Stabilize Only. Then I'd lay that section over the original overlapping the matching first or last frame. The stabilized footage could then be re-positioned over the original footage accurately by temporarily setting the blend mode to difference. Position keyframes for the stabilized footage could be set for first and last frames to match the in and out points. You could then drop your oversized comp in a standard sized comp and animate the scale as needed to hide the edges that move into frame when the footage is stabilized.
I wouldn't even consider stabilizing the entire movie that was an hour and a half long. If you really want to stabilize the whole thing then overlap the stabilized sections by two or three seconds, or even 10 seconds. If the settings are identical you should find frames that match.
The difference mode would also be handy here to find the perfect cut point. When the frame is completely black, cut.
Hope this helps.

You might be hitting some internal limit for simple mathematical reasons. Could be anything from mundane memory exhaustion to some 16bit integer math exceeding the available range of a counting loop or whatever. Not per se a bug, just an inconvenience and more general limitation, but what you are trying to do no doubt could be considered slightly mad... I wouldn't necessarily fiddle with pre-composing like Rick suggested. Adding a border would affect the result of the analysis since it shifts the edge pinning around and it may be more trouble to compensate for that. Instead chop it up into suitable chunks. I wouldn't worry about just extracting the affected regions, either. just let it run in dumb mode on pieces it can swallow, then render it out. Re-import the whole thing and then start editing. Matching frames shoould not be too difficult and, that's the secret ingredient here, differences can be compensated for by using warp transitions with tools like CC Warpomatic, a bit of mesh warp here and there, the occasional other dispalcment effect. Also do not forget that a second pass using Timewarp, RevisionFX' Twixtor and RSMB and possibly otehr tools could introduce additional blending/ smoothing/ fake motion blur that would in many cases disguise the transitions between corrected areas...
Do you really need to use Warp Stabilizer? Or would this be better suited for Mocha stabilization, or Final Cut/Motion's SmoothCam?
In the case of Mocha stabilization, it's the only way I know of to transition in and out of smoothed segments by animating the smooth() expression.
I was having a similar issue over at this thread:
Thanks for the all the tips ....
Yeah it's bit mad trying to process the whole movie, but if that's the deired result why not? (Other than the fact that it don't work! LOL But now we all know...) If it did work I'd have been done and out by now.
I'll proceed per Mylenium's notion ... feels about right.
Just so you'll know I just tried the cut stabilize only, then match position. It worked with Warp Stabilizer was set to Stab Only. Only a coulple of keyframes were required and a little scaling to hide the edges. The shot that I tried was fairly smooth already.
