If you require to move a VC recording from TCS to the Media Library, AND you wish to 'top and tail', the free tool Any Video Converter (available on MyUHI) gives the best results. This video describes the process.
The Media Library accepts files in the following formats: .mov, .avi, .wmv, .flv, .mpg, .mp4, .mp3, .wav, .wma so it will probably not be necessary to convert the video. If it should happen that your video is in a different format, there is a video converter available from AnySoft which is pretty good and easy to use. You can download a trial version here http://www.anvsoft.com/download-any-video-converter.html but the completely free version is installed on MyUHI.
