A few years ago before this Crop_rec module I just import the dng into Lightroom, color grade them and export to a sequence of JPEGs. Then I import them to Premiere Pro for further editing.

Thanks Jimmy, will get one to try asap, can't wait.

It's an experimental build that is separate from the nightly builds, scroll here

I'm not very technically minded... But if the horizontal resolution is 5760, then isn't it the horizontal crop factor something like 5760 divided by the horizontal resolution, eg, 5760/3072 = 1.875 crop factor?

I think proper crop factors use a diagonal measurement, too tired to work it out!

The live view is pretty bad, right now... It's not so much the grey scale but the fps, it is really jittery and looks to be running at about 5fps.

Thanks.

Are you talking about aspect ratio?

ok... So the 3:5K 1:1 centered mode allows for lower bit depths.

at 3520x1320 11-8bit lossless, I could shoot for 20+ seconds

For some reason, i had to force the fps to 24... It was showing 30fps in that mode, even though the camera was set to 24fps

Thanks a lot for your great help. For the "crop" what I want to know is the the crop ratio in FOV, for example if I use a 50mm lens, what is the approximate FOV after using the setting of 3520 x 1320? Does ratio of 2.351 mean the 50mm lens becomes a 117.5mm lens?

I once had a 5D3, but sold it for a 1D-C 2 years ago for 4K, now is thinking to switch back to 5D3 if I can have resolution of around 3K. I need capacity for color correction as I shoot underwater.

BTW, is the live view really that poor with this module? Gray scale is fine for me. Thanks.

3072x1308 (2.35:1) is the sweet spot, right now. Continuous, smallish crop (under 2x)

Thanks. May I know the crop of this resolution? Is that possible to achieve higher resolution if I just need less than 20 seconds of shooting and 10 bit raw only? I am thinking about using it underwater, it is rare to have a clip more than 20 seconds.

May I know the highest resolutions that can be achieve with 5D Mark III with crop not more than 2x? 25p is enough for me. I have been trying to search for this info in Magic Lantern forum, thanks.
