Google Video is basically closing down and many videos will be removed on April 29th 2011. On May 13, 2011 videos that have been uploaded to Google Video will no longer be available for playback.
There is a Migrate to YouTube link to the Video Status page, which will allow easy migraation of any of your own videos to a linked YouTube account. There is also a Download link, so you can download any video content you want to save. The Migration and Download features will be disabled after May 27, 2011.
These changes do not apply to Google Video for Business or Google Video for Education. Business and education users can continue to upload and share videos. If you want to download any of your favourite concerts, now’s the time.
