Hi, I plan on buying a Canon Vixia to make stop motion videos with my macbook. Right now I am using a Canon Powershot to make the videos, digital still cameras do not work very well with frame grabbing programs so I am forced to use RemoteCapture DC, this application doesn't have useful features such as onionskinning. I am wondering if a capture card is needed with macs to capture frames from cameras. I also don't know which model of the Canon Vixia to get. I would hope to find the camera for under 600. Any help would be greatly appreciated. Thanks.
