Add Watermark as Overlay In Video

[bagusok]

Can you add feature watermark in video as overlay?

the watermark can be setting ini top left, top right, botom right, center and etc. watermark alaways in frame of video, if the screen size over than video or screen size ratio and video ratio not same, the watermark always inside the video (not in black screen).

Now, i try using slot, but if screen is full screen and the window size and ratio not same with video size and ratio, the position of slot in the black screen, then i must calculate the position manually by watch the window size.

Thanks.
