Question about the "frame mode" of the GL2, where it basically shoots non-interlaced for the "film look" or whatever.

Is this the same as "progressive scan". Can this lable be applied to the GL2, and state that it is, indeed, a "progressive scan" camera? Or is that a different monster intirely?

Thanks.

Progressive scan captures one frame per pass; frame mode does something similar triggering 2 rapid shutter coupled with interpolation. You can read about this at Adam Wilt's site and Beale's Corner.

Hi Kevin,

You also lose about 1/3 of the vertical resolution because of the way the green CCD is lined up. You see this in the video as macroblocks around high contrast objects. However, this effect is not that pronounced and it gives a very pleasing "film-like" motion. I shoot frame mode exclusivley now, because the video noise is not very noticable (only a video geek like me would even notice it) and people like the "look" better. I used to use Cinelook to make the weddings I shot look like film, but that would take a week to render! Now I just shoot in frame mode to make the video look like film. Best part is it only takes 1 day to render and it's free! Hope this helps.

Cheers,

"Progressieve scan" and "frame mode" are terms often used for the same things. "Progressieve scan" however relates (used to) scanned CRT TV displays which used to work in interlaced mode only. Progressieve scan first became populair with the upcoming computer displays which didn't need the (bandwidth saving) interlaced scan modes. Nowadays many displays (also more and more CRT based ones offer progressive modes often with a variety of framerates. LCD, DLP...and all other pixel based displays need progressive video, sometimes first de-interlaced (= made progressive) depending on the source mode. Frame mode on the other part is more related to the capture part, and like Frank says captures one frame ("all lines") per pass or timeslot. Real frame mode cams don't lose vertical resolution. Pseudo frame mode using interpolation, green offset.. reduce the vertical resolution. Frame mode can be displayed as progressive or as interlaced pictures on CRT devices. Film is per definition a frame mode concept and displayed as a frame display mode (the whole image is flashed at the same time) and this is still somewhat different from progressive mode on CRT displays. Many pixel based diplays however also have frame mode display behaviour, so they are not using a "scanning" mode but rather a flash mode like in film projectors.
