^for me, depending quality of the stream site ..
if they provide HQ, you'll get HQ, if they provide LQ, you'll get LQ unless, you have a software to sharpen it up a bit
for my LQ, i use CYBERLINK power director to correct color and sharpness -- it came out pretty decent ..
if i do the same thing for the HQ that's provided, the QUALITY is sharp, just don't like uploading lots of mb for a 10 minutes clip to youtube
