I came across this on the web and though I would post it here for remembrance.  I like it because it doesn't require the image files to be consecutively numbered.  It generated an .avi file, but I am not really seeing a downside to that.  It should be convertible if necessary.  The source of this information is located here: Click Me!!

Here is the text of what it says:
Stitching images together

Now you'll need to stitch the photos together in to a video.

You can do this on the Pi using mencoder but the processing will be slow. You may prefer to transfer the image files to your desktop computer or laptop and processing the video there.

Navigate to the folder containing all your images and list the file names in to a text file. For example:

Quote
ls *.jpg > stills.txt

On Raspberry Pi or other Linux computer

Install the package mencoder:

Quote
sudo apt-get install mencoder

Now run the following command:

Quote
mencoder -nosound -ovc lavc -lavcopts vcodec=mpeg4:aspect=16/9:vbitrate=8000000 -vf scale=1920:1080 -o timelapse.avi -mf type=jpeg:fps=24 mf://@stills.txt

Once that's completed, you should have a video file called timelapse.avi containing a time-lapse from your images.

If you don't like .avi because of the size of the files, I use Freemake Video Converter...It converts pretty quickly and it's free
