Title: 50D, Rolling shutter 180 and 24FPS
Post by: Edgley on March 21, 2020, 03:28:42 PM
Hi,

I have read, I have played.
I can get the FPS to be 24, but it shows rolling shutter to be 77.

Might someone, please, be able to educate me as to how one achieves both?

Many thanks.

Go to the "Exposure" menu and select "Expo. Override". Then go to the "Movie" menu and select FPS Override. Open the FPS Override (press Func key), select "Optimize for: Exact FPS" and put "Desired FPS: 24. This will do the trick.
If you want more accurate fps, select NTSC video system in Canon menu, open the "advanced" panel on fps override and set the timers A: 750 and  B: 1600.

Thats what I have done, however, its showing a rolling shutter of 75 - I thought one was after 180 to provide the correct looking footage.
I have even played with the FPS Timer A and B to try and get it right.
A - 850 (FT+128)
B - 1411 (+31)

Thank you

Screenshot of your cam's rolling shutter setting, please.

Okay, I take the Muppet of the Day award.
What I should be doing is putting the camera into Tv mode and choosing 1/50.

My bad

Here is the screenshot, which seems to suggest I don't have 180.
