More testing of Video4Skype
Video4Skype is clearly a hot item. Slashdot picked up the story today. According to a spontania representative: “we had 3000 downloads just in 24hrs and our server got colapsed. Right now it is up and running so you can proceed to download it.” In my experience that makes it the hottest Skype add-on ever.
The product also received coverage on the PRZoom Newswire.
Nicolas asked me to remove his Skype User ID form the pic in my previous post because he was getting too many requests for authorizations. (Girls… he is happily married.)
I have tested with about a dozen users now. So just how good is it?
CPU utilization is very low.
It appears to be dependent on where you set “Quality”. With Quality set to mid-scale, Video4Skype used 8 KB/second upload bandwidth and my AMD XP 3000+ processor was humming along at 6 percent. At the highest “Quality” setting of max, the bandwidth was about 20 KB and CPU went to 16 percent. Several other video conferencing systems I have tested consumed 50 percent of my CPU so let’s give a big applause for the Video4Skype development team.Colour is great.
Colour rendition is the best I have every seen, but frankly I am not the best judge of that. I am colour blind, so maybe someone else can render an opinion in this area. Or make your own call with this colour pic.
Resolution: B+.
I use a simple “Eye Chart”...
with three lines of text in Times Roman typeface. 12 point, 11 point and ten point. Buddies who test with me are asked to read it. All can read the 12 point, a few can read the 11 point. I have only found one other video conferencing system (SkypeSee and it is not on the market yet) where the 10 point type could be read. I also use a Video test pattern, 1956 vintage. Tests patterns show Video4Skype can resolve lines at 250 to 300 lives per inch. More applause.
Check Your Bandwidth.
What’s your upload bandwidth? To get the best possible enjoyment from this product start by knowing the upload bandwidth for your Internet connection (and your buddy’s). If you set the Quality to max you will be uploading at about 160 kilobits per second. This will overload anyone with a 128 kilobits per second connection. Voice quality will degrade and the picture will be pixilated (breakup). It would be nice if the developers would add some automatic bandwidth management. If you don’t know your upload speed go to pcpitstop and run the test.So yes Video4Skype is hot. But it deserves the attention it is getting. Very well done, Spontania. Keep up the great work.
