Shutter Speed Readings
« on: May 10, 2014, 12:31:31 AM »
I've searched everywhere. I'm sure everyone says that though.

Traditionally, I've been using ML 2.3 with the most recent RAW module plugin for my 50D supplied from here: http://www.magiclantern.fm/forum/index.php?topic=5586.0

I always shoot my Photo and Video in Manual. Always.

I decided to try the most recent nightly build and was thrilled to find that RAW Video capability was built into the ML firmware! The new font is shiny too.

I was not thrilled to find seemingly different and frustrating shutter speed options. The top of my camera currently reads at 1/50, (as I shoot at 23.976 fps for the extra resolution, so 1/50 fills the 180° rule), and when taking a photo, the exposure is always correct as I adjust through ND filters and aperture / ISO settings.

BUT in Live View it reads a completely different shutter speed and the Live View picture is whitewashed when shooting outdoors, (even though photographs I take with the same settings are exposed correctly). For example, the camera is set to 1/50, but in live view it will read as 1/92 (or any number it would like to). In fact, even when I adjust my aperture I've found that this number changes. I'm not certain of how my frames are being exposed. I also get confusing readings within the ML menu, like "1/92, 94°." When this value is changed within Magic Lantern, my photo settings change on the top of my camera as well. It also appears to loop around through settings when I rotate my click wheel far enough.

All in all, I would like some help in setting an accurate solid shutter speed for 23.976 fps raw video recording, and an understanding of what these units represent. Do I follow what's on my camera's top display or what ML tells me?

Regards and much thanks, ImagineFlight
