So I do commentary on Half Life 2 gameplay and i put it up on Youtube. I use the full version of 'screenflow' which can be seen here,http://www.telestream.net/screen-flow/overview.htm, its fantastic, however whenever there is a large amount of action on the screen the quality goes to crap. I was thinking about getting a external Capture card. Like something that i could plug into my computer to get better quality. Price is not a problem I am willing to pay anything under 500 dollars. Thanks in advanced. If I said something wrong in here please dont leave negitive comments.
