Hanging on export and RAM preview

[GeneralOneBall]

My aftereffects is hanging either when i try to ram preview a part, but it doesn't always hang, just most of the time.

It also hangs when i try to export part of the project which doens't start form the beginning.

If i start exporting form the beginning then it's fine. But if i export for example from 20secs - 30 secs it hangs

but 0secs - 30 secs is ok

It sounds like a RAM error.

What may be happening is that your AE is trying to flush the cache before it renders to the RAM, but is unsuccessful - - a couple of tries later, it is happy and starts going.

If you're EXPORTING, then you're actually rendering frames, rather than simply buffering them.

Rather than EXPORT, why not use MAKE MOVIE?
