Time Lapse manual settings change when switching to Live View

I'm experimenting with time lapse using the inbuilt intervalometer on my 5D MkIV but some odd things happen. I gather it won't do auto exposure changes during the shoot, so I've switched to manual. I do a test shot before turning on the intervalometer, which shoots via Live View, but quite a few times the settings have changed when I switch over and I've no idea why. I end up with poorly exposed images because of it. I also did a two hour moonlight shoot on about 1/4 second but found out that it quietly reverts to 1/25th sec, which I guess is the movie frame rate.

 

Are there any issues with manual mode changing settings, or when you switch to Live View? I'm surprised you can only shoot at 1/25th on Live View as how do you do star tracking shots. Any ideas what's going on?

So were you taking a shot every 1/4 second or was each exposure 1/4 second? I guess I'm not following you. For star tracking shots surely you need, say, a 10 minute - X hour exposure shot on B not an intervalometer?

You can only use full second intervals in the time lapse mode, not fractions, so its 1/4 sec exposures at intervals of 1sec +. I've since found that it is a Movie mode and restricted by that (as is Live View I'm guessing).

 

"If the shutter speed is 1/30 sec. or slower, the exposure of the movie may not be displayed properly" which is a bit cryptic as it suggests exposure will work but the setting will not display in the LCD, or then, it might mean exposure will revert to 1/25 as I am discovering.

You can get away from the movie mode restrictions when using the 5D IV for time-lapse by using the "interval timer" in the camera mode. This will create a stack of images that can be combined to form a time lapse movie. Apple Quick Time 7 Pro, for example, will do this. See . If you want to edit the stack of images, you can use Lightroom and Photoshop CC. See . Edited May 11, 2020 by Glenn McCreery

Thanks, Glenn. For some reason, it never occurred to me that I could edit/render video's in Photoshop!
