Hello all. Can anyone help with this? I have a HD Sanyo-TH1 camcorder and a Sony DSC-W230 camera. At the time I purchased them I assumed I could just record onto iMovie and iDVD in HD as a result. I found out that isn't true--so working with what I have...how do I know what is the best format to actually use to get the best quality? I don't understand for example (when exporting) why there is even an option for quality. Mine defaults to 50%. If the video was worth recording to begin with, wouldn't the average person opt to have 100% quality? Also, how do I know which frame size to use. In the process of converting, exporting, importing I'm often given the option to choose a frame size. I am typically making video to eventually burn to DVD. I have a full screen HD that I want to view it on...however I want to give these disks to other people that all have various television sizes etc. Since I know the HD won't automatically work, and knowing it will be viewed on different tv sets, how do I know what is the best frame size to choose without compromising quality when I finally get it into iMovie to begin with? Thanks.
