Quality Issue Question for FFMPEG *Please Help

Me and my friend have been messing around with the covert command in the video_conversion.php. We have tried multiple modifiers but our streaming quality doesn't seem to improve. Our command line is as follows:

Code:

$cmd_ffmpeg = "$config[ffmpeg] -i '$video_src' -acodec libmp3lame -deinterlace -ar 22050 -ab 32 -f flv $video_flv";

Please, if someone knows how to get our quality up to real good quality, please post the different command lines. On our site, we experience pixelated videos, and when the screen fades out the outstanding character is highlighted with a line. Our quality settings need to be fixed before we can open the site up. Please help me.

Thanks
