Re: moving clouds or sunset
I personally think you get the best results by just shooting normally and then speeding things up in post (unless you're talking about shooting something that takes a really long time).

Re: moving clouds or sunset
Yes, it also depends on the speed and amount of change from the clouds.
I highly recommend capturing time-lapse using a digital camera and then bringing the shots into your editor as a film roll. Then adjust as needed. The images from the digital camera are higher quality than from the dvx. This gives you more leeway to work with.
For capture, I use the software that came with my Canon camera. Run it on a laptop and my Canon attached by usb. I can set the rate and duration and let it go.

Re: moving clouds or sunset
I have used the interval record lots of times. If you're filming something that takes longer, use a longer interval/longer record time (ie: Sunset, moonrise, SLOW clouds, flower blooming). If you're recording something that's happening fast, I have had good luck with shorter interval/shorter record time. Like horsefilms said though, it is better to record normally and speed up in post. Search the threads, I believe there are some conclusive mathematical formulas that can help determine the best interval settings. Haven't had experience with doing it with a digital camera, but I can imagine it would be better because it would save your heads (interval recording IS hard on your camera heads....)

Re: moving clouds or sunset
Has anyone tried the timelapse with a super slow shutter speed? Anyone have any footage? Just curious.

Re: moving clouds or sunset
that was a great tip about using the digital camera. never thought of that.
i'm going to try using dv rack to record in realtime so i can get longer than a tape would last.
has anyone written any software yet that will go through you avi file and pick out x # of frames every so many seconds/minutes etc?
seems like an easy thing to do.

Re: moving clouds or sunset
hi,
in post:
when you speed up 10x, you are getting 1 frame every 10 frames
when you speed up 100x, you're getting 1 frame every 100 frames, so near using a frame from 3 seconds of footage
when you speed up 500x, you're getting 1 frame every 500 frames, about using a frame from 16 seconds of footage
My point is... if you are using only a single frame from 16 seconds of footage, why not use a time lapse to capture 1 frame every 15 seconds ?
Interpolation is a good thing, but more visible when slowing down the footage.

Re: moving clouds or sunset
AFAIK, no way to speed up without loosing frames (progressive or not). You can interpolate, like 25% from previous frame + 50 % current frame + 25% next frame, but this is more effective when slowing down. When speeding up and interpolating you can mix a percentage from frames, but deleting many frames anyway.
If you want to interpolate, you can time lapse every 5 seconds then speed it up 2x interpolating, the result will be like time lapse of 10 seconds. No need to record in real time.

I posted a forumla a while back. Here's the thread:

Also, realize that using the DVX for interval recording costs you, at a minimum, 1/2 second of tape for one interval. That's a lot of running time, tape, wear, etc. for one frame of information.

Re: moving clouds or sunset
Does anyone know of a method for getting time-lapse or interval shots automatically with Canon's PowerShot S410 ELPH...?
I got one to use for location stills, etc and would like to use it for time-lapse, but haven't been able to find a way to do that, yet (Canon evidently didn't feel like building the function in at the factory...)

With my G3 I got a program named Remote Capture. Try finding it on Canon's support site and download it. It might work with your S410.
Or, there's some shareware/freeware apps out there.
