You who uses crop_rec a lot, which option do you use most? I often tend to use center crop. All because of lens characteristics, better performance in the glas etc. But I would have loved higher vertical resolution in this option. Since I only shot 1.85:1 or 1.78:1 and never 2.35:1 there is not so high resolution, since it ebbs out at 1340 or such. But time will tell.

How about you?

How are you shooting 1920x1080 48p ?

What exact canon settings etc.

I keep having Corrupted frames, when I shoot 1080 48p. 45p is close to continues and all frames are whole, but 48p gives corrupted frames no matter what.

I am on fir 123.

Settings from first post, starting from Canon and ML defaults.

There's no more 1920x1080 48p in recent builds, guess why. If you still have problems at 1920x1040 48p, try decreasing the vertical resolution in the crop_rec submenu. How far do you have to decrease it?

Last time I've checked, all crop_rec modes were centered (maybe off by a few pixels, give or take). Is this no longer true?

Last time i tried there were substantial more than a few pixels when compared center crop to 3K crop rec. But it’s not a complaint only wonder what everyone uses :)

Thanks for that!

I can't find the option to decrease vertical resolution on the crop rec submenu and  have the most recent build I believe. How do I opt between the two?

 

Also, I have a doubt that I looked around and still couldn't figure out maybe because it is too basic. Here it goes: does crop rec mean zooming x5 in liveview while actually capturing the equivalent of x3? I struggle with this question because last week I'm pretty sure I recorded in 1080p48 continuous without zooming in.

I initially thought it would capture the whole frame, but then I read it is 5x zoom in liveview and actually capturing the equivalent of x3.
Crop rec is determined by resolution, do you want less vertical you change aspect ratio, for example 2.60:1. Higher vertical 1.78:1 etc..

Ok thanks, very kind of you! So the closest i can get to 1040 is 1:85:1 (gives me 1038). Is that it?

Correct! It’s dependent of aspect ratio..
Otherwise you need crop lines and make the rest in post.

Ok, ok but now when I play around with the camera the image moves like jelly on liveview. Is that normal?

In crop_rec mode slow shutter and low frame rate is normal if you want proper framing.
