If you are using Avid 4 as the editing application on your iMac, you may find that the 1080p/60 videos from Panasonic HDC-SD700/TM700/HS700 could not be imported to Avid 4. One of the solutions is to upgrade to Avid Media Composer 5 with discounts price, to see if it is compatible with the non-AVCHD compliant 1080p/60 28Mbps .mts files. But it is not stabilized with new .mts files yet.
Another solution is to get the free trial Aunsoft Video Converter for Mac to convert the downloaded 1080p/60 videos to MOV on Mac Snow Leopard, and then import the HD 1080p MOV videos to Avid 4. The workflow to upgrade to Avid 5 is to contact the Avid support, and here I would like to demonstrate the workflow to convert Panasonic HDC-SD700/TM700/HS700 videos to MOV on Mac for Avid 4, keeping the 5.1-channel surround sound.
Step 1. Download TM700/SD700/HS700 videos to iMac.
Connect Panasonic TM700/SD700/HS700 camcorder to iMac with USB 2.0 cable, copy and transfer 1080p videos from camcorder to Apple hard drive as video footage.
Step 2. Load Panasonic videos to Aunsoft Video Converter for Mac.
Free download Aunsoft Video Converter for Mac as the Mac Panasonic HD video converter to keep the best video quality regardless of the output file size. Click the "Add" button to load .mts videos, or drag and drop the videos to the application UI.
Step 3. Choose H.246 MOV output format.

Step 4. Convert Panasonic SD700/TM700/HS700 videos to MOV for Avid 4.
