80 hours encoding a 30 minutes video? What’s wrong?

Hi. I have a 30 minutes HD AVCHD footage edited in Premire Pro CS5 with strong noise reduction effects applied in After Effects. The issue is that it took 80 hours to render in H264 with only 1 pass!

Despite noise reduction is an intensive effect to render, I guess 4 days for a half an hour video is just insane. My computer is Core 2 Quad w/8Gb RAM, not the most powerful in town but should do the trick.

Is this normal???

Thank you in advance.

Pablo

Some effects take a long time to render. It is not unusual for a single frame to take minutes to render---for example, when working in 3D or if certain effects are used.

If you had a computer with more RAM, then I'd recommend that you use Render Multiple Frames Simultaneously multiprocessing in After Effects to render and export the parts that you need from After Effects.
