Hey guys, this is a huge problem I really hope you guys can fix. So I am on AE CS6 Version and I am working on a project in a composition with some effects, but not NEARLY enough to cause this much of a problem. So, with these effects, every time I try move a keyframe, or adjust the CTI, or change a single value, After effects lags and freezes for like 1 minute and then continues on normally just to present me with the same issue. So basically every time I make edits in my composition after effects freezes up.


Now for the specs....


- MacBook Pro on OS X Lion 10.7.5

- 2.8 GHz Intel Core i7 Processor

- 16 GB 1333 MHz DDR3 RAM

- Intel HD Graphics 3000 512 MB


In the Media disc cache section of preferences, I have 500 GB alotted on an SSD 1TB external drive (Yes I have tried emptying disk cache)


Everything in the discussion has worked extremely well on my machine, and the problem came up just recently.


-OpenGL is disabled


These are all of the effects included (please note I have used all of the without problem):



-3d camera tracker

-Trapcode Shine


I am also working with 29.97 Fps 1280 x 720 dimensions. The file is a .mp4 with a H.264 and AAC codec.


I really don't know what the problem is. If you are reading this PLEASE take a shot at fixing this. I will be happy to supply ANY more information you guys need so just ask! Thank you for your time.

    I'd do two things: First, I'd transcode the mp4 footage to quicktimes in ProRes 422 (if you have it), PNG or Animation.  Then I'd do the Twixtor work & render it out.  After that, you should be good to go. 

    You're asking AE to do A LOT of  computing by working with a highly7-compressed codec like h.264, PLUS frame rate conversion.


    It also wouldn't hurt to turn off multiprocessing temporarily if you're using it.

    What happens if you transcode the footage into a production codec first and then use it, rather than using footage that uses an interframe compression codec?

    You could use Premiere, but it would be quicker to use the Adobe Media Encoder. Simply load your file into the Adobe Media Encoder and pick a lossless codec for your output. Quicktime with the PNG codec is a popular one. Be prepared for a large file size though, as h.264 is highly compressed compared to lossless video.
