Another raw time interval

This is my second attempt at a really large time interval. I shot in raw at 2 second intervals. I used TV (shutter priority) with auto iso. I started exposure in the lightest part of the sky.

I shot more but only used 724. I processed them as JPGSs with some shadow recovery saturation clarity and dehaze. I did not need to rework any but I did crop to a 16x9 ratio as I did the mass Raw to jpg conversion.

I rendered this in Movavi at 0.1 sec duration and exported at 4k high quality and 29.97 fps. This once again produced a very smooth cloud motion.

I still have a couple of glitches or jumps and don’t know the cause. It took 1 hr 20 min to upload to Youtube. This can be viewed in 4k

Wow Ben, this one is awesome! You are so lucky to be able to have that cloud movement to use. I wish I had some of that here. You just might sell me on that slow relaxing music you are finding too. It's kind of addictive sounding.

I didn't see glitches or jumps, but I saw flickering throughout the whole timelapse. Which camera did you shoot this with?

So yeah, this one to me is awesome in everyway except for the flickering. On my cameras if I do in camera timelapse, the D810 has exposure smoothing to get rid of that, my D850 has both exposure smoothing and an anti-flicker mode.

Oh, and please add .com to the end of www.FocalWorld it should be www.FocalWorld.com

Nice Ben. That location seems a great place to be shooting timelapse or even just imaging. You are also getting a pretty good feel for timelapse now.

Right Jim, this has flickering and I have anti flicker set. This is the 5DSR and it does not have exposure smoothing. I suspect the flickering has something to do with the camera changing iso as the light changes. The shutter speed is fixed, and the aperture seems to be frozen at f5 which is wide open on my 100-400 lens. I need to check if I have the stabilizer off.

The one problem with using shutter priority and auto iso is that it drives the lens to shoot wide open. That's why I have been using , manual, but that has issues too. I will figure this out.

Right now I am very happy with 2 seconds. Its working very well. I also did some flickering research. It seems that this is a big enough issue to warrant several software offerings to fix it in post. But they also say its caused by a slight variance in shutter speed or aperture from frame to frame and even when these values are fixed, just small differences in the camera. They say shoot wide open and use a slow shutter, and maybe even a ND filter to keep exposure in range.

I did one this morning that did not have flicker, but did show small exposure changes as the iso changed. In this case the shutter was fixed and the aperture stayed around f5 for the whole series. Iso started at 1000 and dropped to 400. Each drop in iso shows a slight exposure change.

I am going to try one this afternoon with all values fixed and see what I get.
