I bought the new Sony HDR-TG1 two months ago. I have been using it with great pleasure and satisfactions. You can read: My first impressions.
A lot of people have asked me if I use the HDR-TG1 with my mac. My answer is simply: YES.
The HDR-TG1 records HD video in the AVCHD compressed format. It is a highly compressed format, so one problem is that it produces a ‘“grainy” result when using the camera in low-light.
You need an Intel-based Mac because only a Mac with an Intel processer that use Leopard supports AVCHD.
To transfer and edit the video files, Sony offers with the camcorder a software: Picture Motion Browser Software; however, the sofware does not work with Mac OS X (Only on PC).
Don’t Worry though because Apple provides two great simple and easy applications with Mac OS X: iMovie’08 and iPhoto’08.
