My After Effects CS6 locks up for 3 minutes "Locking Existing Frames" before it even begins to start rendering, every time I need to preview anything - even at the lowest possible quality.
The render goes perfectly normal - it is not the rendering that is the problem - it is the "Locking Existing Frames" process BEFORE rendering that freezes up my computer for 3 minutes, and ruining my life.
I am using Adobe After Effects CS6 on a Mac Book Pro with a 2.9 GHz Core i7 processor (2 cores) and 8 GB of RAM.
Please help me understand what is happening when it is "Locking Existing Frames," and what some solutions could be to reduce the amount of time it takes to do this.
ALSO: I have scoured the Web for hours looking for the answer to this problem, and to this point it has never been solved. If you can solve this issue, Adobe should give you a promotion and $1 million.
