145320 fix my video uploading script

I have a video script I purchased a few months ago, (its one of the flash video clone scripts) I had the video player redeveloped around the same time , I had flash programmer increase the player size, add advertising functions and enhance social features I am ready to launch this site and I need some upgrades to the uploading video script to work better with the new video player. At present when I upload a video file , when it does convert to flash the end result is not good, the video is very pixelated and horrible overall quality, the big size of my video player makes it show more (i have option to show smaller file on player but that is also very pixelated), when I try to increase bit rate and file size (height and width) of video to accommodate video player size , the upload does not work .... I have tried everything playing with varying bitrates and file size (h&W), I think the script has restrictions on the bit rate, video size (MB) and height and width , length (time) I need the uploading script edited to allow any bitrate , any file height or width, I would like to keep the under 100mb requirement but I want to allow any video time length. I want the end result flv file to be great clear , high quality ..... I don't expect tv quality but I want nice looking video.... I considered that the end result could have been my server but looking at other video sites hosted by my host, I see great quality video some over 17mins, so I know its on my end.... Candidate must be experienced with flash, and flash video sites (youtube clones), php-mysql ,
