This guide on video watermark will enable you to place an image watermark or text watermark over an existing video. Please note that some basic working knowledge of VirtualdubMod would be an advantage, but not a necessity.
To watermark watermark, you must re-encode your video, so it is suggested that you would use this guide immediately after acquiring your source, just before you are about to re-encode your output.
Part 1: WATERMARK PRESENT FOR ENTIRE VIDEO
This part deal with how to place a watermark in your video for the entire duration of the video. If you want to watermark only at certain time, or certaibn interval or different watermarks on same video at different section of video,then read the guidence on Part 2 below.
Now lets start Part 1
1. PREPARE YOUR WATERMARK IMAGE
a) If making a text watermark:
Open up your favourite image manipulation/creation program. Create a new image – I’d suggest a canvas size of 200 (width) x 20 (height) as a good starting point, but you can use whatever you like, just bear in mind how it will look and fit on the screen. Use your image software to paint the background black. Now create the text you wish to appear in the watermark, and place it on the black background, making sure that the text colour is white. Once finished creating your watermark image, save it, but make sure that you save it as either a .BMP or a .TGA file.
b) If you are using an existing image:
Simply open the image, and make sure you save it as a BMP or TGA file.
It is imperative that you save your watermark as either a .BMP or a .TGA file, as these are the only file formats virtualdubmod will accept for watermarks.
Some examples of watermark images appear below:
2. SET UP VIRTUALDUBMOD
Open Virtualdubmod, go to File > open video file:
Select your source video and press the Open button.
