I'm trying to use a Sony Bloggie 3D stereoscopic camera to upload anaglyph video. This cool feature added by YouTube some years ago is now broken. Adding the necessary meta-data to my video file is far too difficult. There used to be a YouTube video tag that made 3D very easy. There was also an option box in the advanced options for my video which is now missing. YouTube please fix this problem. I'm also trying to use magix Vegas Pro 15 and running into problems.
