Open a new animation , with a transparent background , ie , you should have the white-grey checkboxes . Then select the Text tool [ the tool with a block A in the toolbar ] and click on the first frame , where you want to position the text . The text box will pop up , in it , you select the font/size/colour and then write your text and click OK . Now you have the copyright on the first frame , now duplicate this frame as many times as the no. of frames in your actual animation [ Say , your actual anim. has 67 frames , the text anim. should also have 67 frames ] Now select all the frames of the text anim , by Ctrl+A , open the actual anim. window , and "Paste Into Animation" by Ctrl+E . So , all the text frame will apear on the video frames.
