Sure.

To take the pictures at regular intervals I use a free piece of software called 'Boorucam' which can be found here: http://lumai.se/bc.html. It's a very 'lightweight' program that's very easy to use and yet has a lot of options. In the options you can set the intervals and such and check the box to start making photo's. Simply uncheck this box when you're done and it's set.

To make the timelapse movies I use another freeware program namelijk 'Virtualdub', http://www.virtualdub.org/download.html. This program is one of the most favourite tools for any movie editor and can be used for alot of purposes.

Firstly you'd have to rename all your photo's so they form a sequence, such as Image-1, Image-2 etc. This can be done easily by selecting all your photo's and sort them by Date. Next you right click the very first picture and select 'rename'. Now you name it Image (1) and when you press enter your computer will rename all the photo's to form a sequence. Simple trick that's supported by Windows itself!

Now if you load up Virtualdub and press File -> Open you just have to load the very first photo and it'll load them all together. Next up I always go to Video -> Filters and click Add in the window that came up. Here I select Resize and at 'Compute Height from Ratio:' I enter 16:9. Which is to avoid Youtube from stretching it to their HD resolution. Next up you select the Compression at Video -> Compression. I've always used XVID MPEG 4 at a constant bitrate of 4000 for my timelapses that I have uploaded. Lastly you can set the Frame rate to your desire at Video -> Framerate. I often set this at a decent rate around 40-50 for full day timelapses so the video length stays acceptable and the cloud motion or should I say 'rolling' is nicest to see. But the Clouds are my main interest in this case . You can also add Audio if you like but i've never seen a use for that in my kind of timelapses. Lastly you go to File -> 'Save as Avi' and it'll start encoding at the set settings, which can take a while depending on your computer.
