Unobtrusive Table Sort Script (revisited)

Very impressive work

At a glance
Plays nicely with the JavaScript global namespace (the script creates and reuses only one JavaScript object)
The new script sorts (on average – based on my very non-scientific calculations), 5 times faster than its predecessor
The script’s plug-in architecture makes writing custom sort functions a breeze
The script can now highlight both alternate rows and full columns on a table by table basis.
Like its predecessor, the script is fully keyboard accessible
The script can correctly determine a columns datatype should a datatype not be explicitly defined
The script is smart enough not to sort columns containing identical data
Sort routines can now be initiated using JavaScript
Tables can be automatically sorted on a column of your choice
Before-sort and after-sort callback functions can now be defined

Extracting good stills from video

I need to extract stillframes from video automatically when I compress and autopublish some .flv and .mp4 videos. It's pretty easy to configure FFMPEG to do this at a pre decided frame but I need to be shure that I don't get a blurred out image!

I think the best way would be to define an area lets say 1/3 into the clip an scan it for 50 frames or so to decide wich frame has the least movement. Does anyone know of an easy way to do this?
