older camera - imovie HD
My sister-in-law has been using a high end Sony video camera for 12 years to make videos of birds. She started with an iMac and moved to an eMac and now is looking to upgrade to a new desktop with iMovie HD. Unfortunately, her old Sony 720 camera is in the 4:3 format, rather than 16:9. Will she be able to use her old camera with the new Mac, with iMovie HD? I understand about adapters for Firewire 400 to Thunderbolt, but what will her movies look like?
iMovie '11, OS X Mountain Lion (10.8.5)
