Thanks a1ex! :) So you said what I was actually afraid of - looks like there are only 2 options for 50d users:

  • full auto mode (Expo Override off), which only gives me control over aperture and Canon adjusts ISO and shutter reacting to light conditions
  • Expo Override enabled, which gives me full control and manual exposure, however unlike the option above, Canon does not change anything automatically

Thanks, halbmoki! Just to make sure I understand you correctly, currently there is no way (at least for 50d) to have shutter speed in auto mode (h.264) different than 1/32?

And, from my observation it's even crazier in MLV RAW recording. In M mode, live view display always show ISO100 even if exposure pane is set differently. When recording, settings do not change even if exposure override is disabled. But in Av mode, it works more less as with h.264 recording, with shutter set to 1/32. Do you also see the same behavior? Is it worth reporting as a bug, what do you think?

Thanks, yes, looks like Expo override does the trick and I'm able to set faster shutter speeds eg. 1/60s, but side effect is that all exposure settings stay the same throughout the entire capture and do not react to changing light conditions like in the default auto-exposure. Maybe there's another setting in the menu, going back to my research.

Dear fellow 50d owners:) I have some issues understanding the concept of movie mode implemented in current nightly. It seems that Exposure Override option is dramatically changing movie behavior. Having it disabled, no matter what you set before recording, ML tries to keep shutter speed close do 360deg, which for h.264 is around 1/30, changing the ISO accordingly when moving from bright to dark scenes. With Exposure Override enabled, you set settings before recording and ML honors them but not adjusting for changing light conditions. Could someone be so kind and give me a hint on how to override standard shutter speed of 1/32 to shorter value, say 1/60, to achieve 180 deg, but still keep the possibility of automatic exposure adjustment? Is it at all possible in 50d?

Thanks
Greg

@drkamikaze: I'm currently looking for the easiest yet still flexible one and as of today my preference would be:
1) shoot mlv
2) raw2cdng for conversion to cdng
3) davinci resolve for everything else (debayer, edit, color correction, output). For color conversion using VisionLOG, however that is still uncharted land for me

I'm returning to magiclantern after couple of months and I must say I'm slightly confused by wheels behavior (or rather their influence on movie recording parameters). First of all, the main difference between the version I used to use and current nightly is lack of colors for indicating good values of aperture and shutter values. But bigger issue is the difference in controlling aperture and shutter, or better, my lack of understanding current configuration of ML ;)
So in the past, in M mode, by turning one wheel I was able to change aperture while the other one controlled the shutter speed and display indicated I'm going outside "safe" values by going from green to red for shutter speed. Now with the most recent nightly, one wheel modifies f-value but the other... does nothing, or to be strict, does not change what it displays on the back display (shutter stays at 1/32), but top LCD shows shutter speed changes. Also, ISO changes in response to changing light conditions while for the version I used to use in the past it stays as originally set. I'm puzzled ;)
Can someone be so kind and explain that to me?

Thanks,
Greg
