Once the video starts streaming, the phone automatically starts recording it directly to memory. This is so when the video ends, you can choose to save the video. This is a pretty good idea in theory, but not so much when your phone has limited memory to begin with. We would've liked an option to refuse to have the video be recorded.
Performance can be a little shaky, however. There is a noticeable delay in video streaming, even with 3G. We calculated a delay of about half a second. Also, video quality is dependant on the quality of the camera. The resulting video on the recipient's end was shaky, choppy, blurry, and pixelated. The sound quality was pretty good, however; it came through loud and clear.
A more significant problem arose when we couldn't always get the Video Share option to show up during a call. We believe this happens when we attempt to make a call when the 3G network wasn't available. Even though 3G is available in over 160 markets in the country, sometimes it's not always possible to get that high-speed connection, which is a good thing to keep in mind if you're considering 3G services like Video Share.
A brief interview with an AT&T representative revealed that the company does plan to integrate two-way video calling in the future, plus it hopes to have the video stream over to a Web site or television set as well. If AT&T manages to upgrade the Video Share service as it suggests, and if 3G becomes more widespread, we definitely see it as a wonderful feature that's worth the extra money. Until then, however, the AT&T Video Share service is only for first-adopters and those who don't mind giving new technology a try.
