I want to write an application, which among other things will interact with a camcorder, and I'm researching whether it is possible to do using some inexpensive (<500$) camcorder. I have never used a camcorder before, so any information will be appreciated. Here is what the app is supposed to be doing:
Tell the camcorder to start recording
Record for 2-3 minutes
Tell the camcorder to stop recording the current file and start recording the next one
Download the latest recorded file to the computer and do something with it
Now, I figure that most of this can be done using a LANC-compatible camcorder. However I have problems figuring out how to download already recorded files while simultaneously recording a new one. I understand that most camcorders won't allow me to record video while being connected to the computer via usb/firewire, is that correct? Is there something I can do about it?
I'm also interested in other approaches to doing this (I've considered using a GoPro for example, but it has the same problem - cannot shoot while connected to USB). The quality of the video should be somewhat high - at least 720p@60fps. 1080p@30 may also be enough.
