Heya,

I got a call from the DOP of a small student shoot today after he and his 1st AC (both fairly new to this like myself) were doing some test shooting for a short film coming up, with a query regarding playing back the footage.

Apparently, the frame size of the footage being played back was significantly smaller than what he was framing for in the evf. Him and the 1st AC weren't sure why and I didn't get much more info than that but I couldn't find anything here or on the reduser forums that might provide an explanation so I was wondering if any of you could offer any.

It's quite possible that it's a rather simple explanation that we've overlooked and we are doing another test on thursday but I thought it best to anticipate not finding an answer and cast a net out on here so that by friday I'll have a good idea either way.

Any thoughts? Cheers

Kind Regards,

Marcus Allemann

Most monitors run in so called "overscan" mode in default. They crop edges slightly, that's why the pro versions have a button (or a muenu function) that is called "underscan". If you activate this you see the full framing.

Well, it sounds like something is set wrong somewhere, or perhaps you were looking at the wrong framelines. The Red EVF image has a lookaround area, so what gets recorded is smaller, inside that... but that's what the framelines are there for. In playback, all you'd get is the actual area recorded.

Of course, there is a possibility that your playback monitor has been zoomed in, for whatever reason. It may be better to look at the files on RedCine-X.

$500 says that they have the camera set to do playback at 1080p. When you are doing playback at 1080p, any 720p monitor (RED LCD, EVF, and most 17" HD-SDI monitors) will play a center, 720p crop of the footage. Turn it back to playback at 720 and you won't have any issues. I would be shocked if that's not the issue.
