Timelapse on XF305?

I want to shoot some changing storm clouds over the mountains in timelapse, but in the videos I see online, the clouds change too fast. My guess is that they are shot at 1 frame per second, which is 30X real speed. I am looking for a more leisurely pace--say half of that.

The logical thing to do is to shoot 2 frames per second, so it is only 15X real speed.

But I wonder if this would make the movements of the clouds seem jerky?

Anyone have any experience doing this?

Thanks.

Re: Timelapse on XF305?

Hi, ive had good results with one frame for every few seconds and the slower 1/4 shutter, more than one fps made it look jerky and didn't like. Just record some shots with a few different settings and then review t in the XF utility software, there you can see the complete camera settings for each shot.

depending on the speed of clouds you could tweak the time intervals. be shure not to overexpose.

best

Re: Timelapse on XF305?

If it's just a short sequence then you may as well just shoot video & speed it up in post.

Re: Timelapse on XF305?

Hi Bob,

I shot this cloud timelapse at 1080/24p, at 1/48th shutter. I believe I used the 1 frame per 2 seconds setting (at 24p. I think at 30p there's a 1 frame per 1 second.)

Clouds Over Monument Valley - YouTube

In the past when shooting on an XL2, I would shoot for a long length of time (to capture sunrises, sunsets, clouds, etc.) and speed it up in post, just like Nigel suggested.

Overexposing could be a potential problem, but I actually think it adds "character" (shadows?) to your timelapse footage :)

Best,
