We’ve been very impressed with YouTube‘s native iOS app in recent weeks, but it’s very much a watch-only experience – there’s no way to upload videos using it. Now we know why: Google has launched a separate app called YouTube Capture for shooting and sharing video on iPhones (with Android to come later). The sharing isn’t just for YouTube though: the app can push videos to Google+, which isn’t a surprise, but also Twitter and Facebook. In that sense, it’s a more-open video equivalent to the standalone Facebook Camera app that came out earlier in the year. The ability to add in free (licensed) background music from YouTube is also interesting. But mostly we think YouTube Capture could be a useful tool for music artists looking to flesh out their YouTube channels with on-the-road or in-the-studio footage.
