If unwanted text appears at the top or bottom of a video file that you have created or are playing, it is because you are using a LEAD Video Codec in an evaluation form. The Multimedia toolkit comes with evaluation versions of the video codecs, but the video codecs must be purchased separately from the Multimedia toolkit. For a list of available LEAD Video codecs, refer to our website at https://www.leadtools.com/sdk/multimedia/codecs.
