呵呵,还是看看Borland是怎么解释的吧!
An animation control is a window that <font color=red>silently </font>displays an Audio
Video Interleaved (AVI) clip. An AVI clip is a series of bitmap
frames like a movie. Although AVI clips can have sound, animation
controls<font color=red> only work with silent AVI clips</font>. TAnimate works with
uncompressed AVI files <font color=red>or AVI clips compressed using run-length
encoding (RLE).</font>
