What you can do to a video after uploading it to MediaSpace

After a video is uploaded, it is converted for optimal playback. You cannot preview or publish a video during conversion. If media is waiting for moderation, you cannot preview or publish it until it is approved. You can edit media information during conversion and while waiting for moderation.
