battery lasts for around 2 hours. the camera records in 1080i, not 1080p/720p/standard def. you usually can record with the ac cord plugged in
I'm new to the HD recording aspects of life, and I'm looking to buy the JVC GZ-HM320 at Costco fro $350, and I had a few questions.
1: What's the difference in battery life when I'm recording in 1080P, rather than 720P or SD?
2: If the battery life sucks when I'm in HD, can I record while I have the power cord attached? (not necessarily charging the battery, but just powering the device, this is my noob question)
