Video Thumbnail generation

Can anyone tell me how to change the settings for the generating of video thumbnail, and how to regenerate the thumbnail for videos that have a black thumbnail?

The black thumbnail video is caused by it grabbing a frame from the video too early. There is a post in the forum here that explains how to reset this. I will see if i can find it. Do a search, you might run across it.

It might be here

thxxx!!!and  here if some one wants to change the  thumb pic if you  don't  want to take a thumb  in the  beginning  of the  video

you  can change it from here

Line 259

/flash/modules/video/inc/functions.inc.php

function grabImages($sInputFile, $sOutputFile, $iSecond = 0, $bForse = false)

I changed it to

function grabImages($sInputFile, $sOutputFile, $iSecond = 20, $bForse = false)

I thought  i just  share  it  with you :)
