Well I would jump stright into using ffmpeg. You can also do it using ImageMagick; however the docs state you need ffmpeg installed, so why have the middleman?

I haven't tested this, fair warning.

/*   cmd                 img series    codec       bitrate framerate  optional -s WidthxHeight and output filename */
exec(ffmpeg -f image2 -i image%d.jpg -vcodec mpeg4 -b 800k -r 12 video.avi);
/* For Mpeg4 *

/*For FLV */
exec(ffmpeg -f image2 -i image%d.jpg -vcodec flv -b 800k -r 12 video.flv);

If you want to use the outdated mpeg2 or mpeg1 formats you can do that as well. I would suggest connecting via ssh and testing these commands, and hopefully you have ffmpeg installed. a ffmpeg -formats will show you which formats are supported:

See the docs: http://ffmpeg.org/ffmpeg.html#Video-and-Audio-file-format-conversion

and this great answer which I stole various things from:

Image sequence to video quality
