what's the best way to store events in zoneminder ?

I have done some experiences with events storage. I'm a newbee with jpeg and movie compression.
is mpeg-4 more compressible than just a lot of jpeg files in an event ?
what zoneminder's users usually do with event images ? Do they stay the events just as jpeg files or it's normal to convert to a movie in avi, mpeg and so on ?
This is the first part of my experiments:
First I set up my camera with 320x240 resolution. I changed the default value for ZM_JPEG_FILE_QUALITY from 70 to 100.
I also changed the function to modect and put an area to monitor movements.
I saw the files from the movements I did in front of the camera took an average of 77KB each jpeg file.
I also did the same with a quality of 50 and the files took 10KB in avg with the same resolution.
Now I'm going to try with different resolutions and jpeg qualities. I think it would help anybody who want to know how much space is required for an specific condition.
