What operating system? What processor?
Consider that After Effects 7 came out long before the current Mac OS operating systems and processors existed, so there is no way that the application could have been written and tested for that system.
My old one was a power mac G5 running 10.4
My new one is the new iMac running 10.6.5 with the 3.06 GHz Intel Core i3 processor.
I realize that AE 7.0 is old but it just seemed odd to me that a newer computer with more processing power would be having trouble.
Wondering if there is some setting or quick fix? I will certainly upgrade if you think this will solve my problems.
One major difference (huge, actually) is that After Effects 7 is a PowerPC application. The only way that it can run at all on an Intel processor is in the Rosetta emulation mode---which is to say that it can't run effectively at all. Frankly, I'm surprised that you got as far as you did.
If you have a new computer, you need an application written for its processor. After Effects CS3 and later were written for Intel-architecture processors.
Thanks so much for the explanation! Looks like I gotta break out the wallet once more....
At least I can get back to work though.
Moving from AE 7 to AE 10? You are going to love some of the new features. Also, your renders will go faster.
