I've been asked quite a few times to reencode some of my TGS videos with a better resolution and if possible a better framerate. So I'll put online some of our videos from the TGS in 720p and 640x360 resolution, using a 50 fps framerate (PAL camcorder). Let's start with the DMC4 presentation.
The 720p versions use the WMV9 Advanced Profile codec (WVC1). If you are using XP SP2, simply follow the link on the video download page to install its latest version. If you are running another version of Windows, simply open the video with Windows Media Player and it should download another version of the Codec. MAC and other OS users should use the latest nightly builds of VLC.
