extremely strange mac pro behavior with FCE

[Macpropro80]

Hey everyone, Right now im working on a video at school. We have 2006 Quad core mac pros with final cut express. I exported my video in 1080P and it took about 20 minutes to export. But when I went to export it in standard def it says 1 hour remaining. Why is HD exporting 3x faster then SD? Im really confused. I have plenty of ram and CPu Im lost.

Were you editing in SD or HD?

Could be that if you were working HD in the timeline and are outputting SD, its having to reprocess the data more, causing the longer export time?

Cant say for sure, but thats my theory.

thanks, it was actually neither, it was footage from a screen capture program so it would have to resize it either way.
