 *

 * Sometimes Vegas' Smart Resample doesn't do a great job of determining

 * when a video event in fact needs to be resampled.

 *

 * One area it fails in is taking certain Quicktime media in PAL format

 * and placing them in an NTSC project or rendering them out as NTSC.

 * Sometimes it's ok, but if you've ever used Quicktime media captured

 * by another NLE (FCP, for instance), you'll notice severe

 * flicker on your output monitor even if you check the "Reduce Interlace

 * Flicker" switch.  This can be a HUGE problem if you've got a large

 * project in multiple files and you'll be outputting various formats

 * (web, NTSC, PAL).

 *

 * The Flicker Buddy is a quick way to set your flicker and resample

 * settings for either selected media or media with a certain type of

 * extension (of course it defaults to 'mov' since I'm using it in a

 * setting with lots of media captured in FCP).

 *

 * In my case, going from PAL Quicktimes captured in FCP and rendering

 * to NTSC on Vegas, I had to reduce interlace flicker and disable

 * resampling.  All other media (AVI, other animations) were fine.

 * When outputting PAL, I wanted to turn off 'Reduce Interlace Flicker'

 * and enable 'Smart Resample' to get the render times back down.

 *

 *

 * USAGE:

 * If you have a certain set of media on the timeline you want to affect,

 * select them and run the script.  If you want to affect all media of a

 * certain extension, just run the script.  Set your options in the dialog

 * box and click 'Apply'.
