As you know, like other products, Google Picasaweb also have API to access your data in picasaweb. You can use this API for uploading photo, video to your picasa account. However Google limits 100MB for video size. You can’t upload a video larger than 100MB.
Of course, i write this post to inform that i already have a script that can bypass the limitation. It can remote upload a video larger than 100MB, even larger than 1GB to Picasaweb and returns some links as direct, feed, alternate, etc..
You can check it here: http://code.ptcong.com/demos/picasa-video-uploader/
I stopped selling this script
