There were more defined clouds today than the last time¹Also the first time. I tried a backyard time-lapse video. I figured it was a good time to try again.

There was more wind, so I decreased the interval between shots from 30 seconds down to 15. I should have used a 5-second interval, or even shorter.

I also need to get an AC adapter for my camera. Keeping my point and shoot camera on for 350 pictures really depletes its battery. The cold weather doesn’t help.

  Also the first time.

Today I wanted to try to make a time-lapse video. Unfortunately, the weather wasn’t cooperating.

I put my Canon Powershot S100 on a tripod and aimed it out the back window. I started the CHDK time-lapse program with a 30-second interval.¹I used a long interval because I couldn’t see any cloud movement. In retrospect, I should have gone with a 10-second interval. Then, 141 pictures later, I turned the camera off.²The battery indicator was blinking its warning. If I do this much more, I’m going to need another power source for the camera.

I used Picasa to put the pictures on my computer and export them at 1000 pixels wide. I cropped the images to 16×9 aspect ratio³This seems to be the right aspect ratio to avoid getting black bands on the side of the video on YouTube. using IrfanView in batch mode and converted the cropped images to an AVI file using RAD Video Tools. I uploaded the AVI to YouTube.

I was surprised to see cloud movement in the resulting video. Watching out the window didn’t reveal any movement.

I also tried a bunch of online animated GIF converters, but using only 30 of the images resulted in an animated GIF 1.81 MB large!
