Frames rate in capturing sunrise/sunset

I will be capturing a sunrise/sunset soon in Adobe using Stop Motion capture. How may seconds per frame should I set? 1, 5, 10, 20?

Depends solely on how fast you want the sun to rise/set :) If you select 1 sec for frame, it will be 30x faster than "realtime", if you select 20 s/frame, it will run like crazy. I guess you are safe with 5-10 secs per frame. You can always speed up in post.

Obviously err on the side of shooting too many frames per second as you can dump the ones you don't afterwards. Depending on exactly what you're after you might allow maybe 40 minutes for the sun to go from a decent way above the horizon to completely black (don't foget to give it plenty of run-out time or you'll have to do a really quick dip to black). So for an on screen shot of 15 seconds that would be one frame every 7 seconds or so. So maybe go for 1 every 5 seconds?

I'm always a bit "out there" and have a tendency to do things differently.

Specifically, I record the whole thing at the full frame rate including a tape backup. You only get one shot (usually) at a sunset in a particular locale and I don't like to risk screwing up because of a contrary computer or, as has happened to me, something wandering across the field of view such as a person or a bird. If this happens on the one frame you capture at around 7 seconds (for example), you are lumbered with it. If you have the whole event, you can simply shift the starting point of the sequence to avoid it. One other potential benefit is that you can apply some averaging the 7 x 30 frames that you will have for each final frame in the sequence and reduce noise.
