The Sony Ericsson Vivaz was announced in January, 2010 and 3G.co.uk covered the story here - Sony Ericsson Vivaz - HD Video Mobile.

The Sony Ericsson Vivaz has a dedicated video key as seen in the demo below. Click the key once more and you are recording HD video footage – click again and it stops.

You can share your video via YouTube and this is preconfigured on the Vivaz. You can setup a YouTube account, if needed, via prompts on the Vivaz.

You can also share your video via the “photo and video album panel”  To share your HD video all you need to do is select the video you want to share and then select “send as” and follow the prompts as shown in the video.

The fastest way to upload large HD video files on the Sony Ericsson Vivaz is via Wi-Fi whilst a photo will go relatively quickly via a 3G network connection.
