Since aspect ratios have often been a hot topic on Screen-L and since frame grabs were recently mentioned, I thought I'd bring the two threads together with this query: Has anyone had trouble getting a true 4:3 (1.33:1) aspect ratio when doing digital frame grabs from VHS video? I recently installed a Matrox G400-TV tuner and video capture card in my PC. It'll capture MOTION video at the standard screen sizes of 320x240 and 640x480, which are precisely 1.33-to-1 aspect ratios. However, when I use Matrox's "Video Snapshot" software to do STILL captures, I get frames not quite 1.33 and it's annoying the heck out of me. Instead of 1.33, each "snapshot" is the oddball size of 688x470 pixels or 1.46 to 1. I'm using this system to create images for the new edition of <shameless plug> TELEVISION: CRITICAL METHODS AND APPLICATIONS and I need the precise aspect ratio or the frames won't appear correctly. Any suggestions? ---- Jeremy Butler [log in to unmask] ScreenSite http://www.tcf.ua.edu/ScreenSite Telecommunication & Film/University of Alabama/Tuscaloosa ---- Screen-L is sponsored by the Telecommunication & Film Dept., the University of Alabama: http://www.tcf.ua.edu
