Anyone had any better luck than me working with AVCHD files and their Macs? I just had to buy a Windows laptop because I was so fed up with how terribly my imac works with AVCHD. First you have to convert the MTS files to MOV using imovie to do anything with it. That alone takes about 3 minutes for every minute of video. That was importing at imovie's optimized 960x540 setting too, not even importing at full HD! Importing at full HD is just painfully slow. Then you have to edit and render it back out to MOV which takes another 4-5 minutes per minute of video, even rendering to 1280x720 at 5Mbps, its ridiculous. Windows can work with the MTS files right off the cam, no waiting around for it to convert to another format just to edit it. Rendering to WMV is a breeze too. A 1280x720 HD file at 6Mbps only takes a tiny bit longer than real time and full 1920x1080 at 7.3 Mbps only takes about 2 minutes per minute of video and the final file sizes are way smaller than MOVs while retaining the same quality. Having said that, my Windows laptop is running an i3 processor with 4GB of RAM as opposed to my imac with a core 2 duo and 2GB, but still. I love my Mac, but working with AVCHD files are just awful with it.
