In our latest update we have upgraded our video encoding to bring you faster encoding and enhanced quality. In the future this change will allow you to check out your GPS tracks and videos on smartphones, such as the iPhone or Android-based phones.
For those of you interested in more technical details, we have now switched to H.264 encoding. We are closely following the latest WebM developments and are planning to switch to it at some point soon once the browser support is ubiquitous, as we are open source advocates. We will watch the release of the next Flash versions with interest, as it should push the support for WebM to the masses.
