Hi Guys
Can anyone tell me how I go about making the effect where clouds are moving quickly in the background but the rest of the scene is running at normal speed or even slower?

Thanks guys
Wayne

I would think you could use two instances of the scene on two tracks. Mask out all but the clouds on one and increase the speed of the clouds in the other.

Thank you Terry I will try that, glad someone knows what they are doing.

If you are using FCP, Motion has clouds under "content". You could export the clip to Motion and add the clouds. Terry's suggestion should work as well provided you have enough length in the clip to get the effect you are looking for.

Mask out all but the clouds????

Im using premiere elements 3.0. How would I "mask out" the clouds?

Richard Wakefield · May 14th, 2007, 11:50 AM

u could just chromakey the blue sky out and replace with cloud timelapse? u'll need to use masking too if there is blue elsewhere in the clip. all of that is fairly standard AE stuff.

(Kim: masking is just basically keeping wanted areas on a layer, similar to photoshop in a way)

or do what i do and cheat: put cropped cloud footage underneath a photoshop layer of the roof of a building/church from the clip :)

did u possibly get the idea of this from an old highlights clip of mine???

Do you mean me Richard, getting the idea from your site?

Noooooo I wouldn't do that......Honest ;o)

It is good though.

Thanks Richard

Wayne Greensill · May 14th, 2007, 12:41 PM

Any ideas?

Thanks
Wayne

well you have two options:

u choose a perfect day and just film them urself

OR

loads of footage stock libraries on the net offer cloud time-lapse:
http://www.skytimelapse.com/clouds1.html
http://www.fotosearch.com/thinkstock...clouds/THK745/
http://www.freestockfootage.com/lsch_Sunset.html

But the best in my opinion is from Andrew Kramer
http://www.videocopilot.net/realclouds.html

his After Effects tutorial DVDs are stunning and a great insight into AE's capabilities, def. worth buying!
