I've had a Panasonic PV GS-500 camcorder(DV tape) for years but want to eventually switch over to HiDef. I got a middle-of-the-road 1080p camera Hard drive & SD cards). Can I use the lowest res setting on my HD camera and still edit the file as camera#2 on my video shoots? I know the quality will differ some but will I have problems syncing them?
