<p>The principle is the same: normal film/video is 24/25/30 (depending on your standard) frames every second, you compress the time by INCREASING the time interval between frames.

oops didn't get in 5 seconds...Good one dwwilson. I have some extra things to add: In Post Vegas for example can only speed up or slow down by a factor of 4, so an hour sped up would be 15 minutes. However, there maybe plugins that will extend the range such as Twixtor. In production, the best in camera time-lapse work I've seen is Adonis Pulatus, he recommends one exposure every 1 second with a 1/2 second shutter time--this gets rid of blipps. Most experienced in camera time-lapse pros will recommend "Drag the Shutter" to make things smooth as you can't really fix the blips in post.

<p>I need to shoot the clouds and how they are moving during the time. I saw a lot of time similar clips on youtube and always shot it is just a set of animated photos. Am I right? If yes, is there any special name for this approach? Or is it just an accelerated video?</p>

I need to shoot the clouds and how they are moving during the time. I saw a lot of time similar clips on youtube and always shot it is just a set of animated photos. Am I right? If yes, is there any special name for this approach? Or is it just an accelerated video?

I think what you're thinking of is time-lapse photography. In a sense it *is* animated photos, except that the "photos" are captured with a video camera.

You can certainly Google time lapse and get hundreds of good ideas for creating time lapse photography, there are two methods for doing it--in-camera, and post-production.

For in-camera, you're generally going to be shooting 1 frame every x seconds. The larger "x" is, the longer the time lapse will last, and the more time between each frame. I usually run some tests starting at 1 frame every 30 seconds and adjust from there. It take a lot of time to test, since you have to go through about 200 frames to get a true sense of what the motion looks like.

In post-production, you would just take the 1hour clip you photographed in real time, tell the software to make it, say 30 seconds, and the software will automatically pick out the frames it'll show you during playback. Again, it's like animated stills, one frame at a time.

The principle is the same: normal film/video is 24/25/30 (depending on your standard) frames every second, you compress the time by INCREASING the time interval between frames.
