YouTube Remixer & YouTube Mobile Go Live
The YouTube Blog announced that they have launched YouTube Remixer, a Web-based editing tool created by Adobe to edit your videos and mix them with other videos. Hat tip to Gary on this, plus you can see detailed screen captures at Techcrunch.
I tested this on my Treo. The videos open in Kinoma and are fairly optimized for mobile speeds (i.e. very poor video quality). Here are screen captures of the YouTube Mobile interface from my Treo.
