I have 2.16Ghz Core2Duo MacBook Pro with the max 3GB RAM. I tried a editing some AVCHD video today. Importing wasn't bad, it took about 25 minutes for a 15 minute video. But exporting is taking A LONG time... Using iMovie 08, exporting a 15 minute 1080i H.264 file to a FW800 drive is estimated 320 minutes! That's with no other apps running. Does that sound right? 5 hours to encode 15 minutes of 1080 video?
