A library for creation of video files based on the Watermark Master application.
BSEditor: Creation of watermarks.
Watermark Master enables adding watermark to a Movie (to its every Frame) or a graphics file. As a watermark one can use:

* Text
For a text one can preset all basic attributes (font, color, size, etc) as well as rotation angle, transparency, stroke color and width. Starting from version 1.1, a text can be filled with gradient or pattern. A text may include dynamic variables: name, extension, duration, size, date, frame width and height of an original or produced file.
Simple Text, contents of a text file or SRT file can be the source of a text watermark. When it is necessary to edit a great number of files and add a text watermark to each of them, it is convenient to make a text file the source and assign its every next line to be a watermark for the next generated file.
When using a SRT file as the source, the text is displayed for the time period that is specified within the file. You can use either existing SRT files or made by your own ones to Create custom subtitles.

* Image
An image can be resized and rotated arbitrary. Also for images one can fix transparency level and transparent color.

* Animated GIF
An animated GIF can be resized and rotated arbitrary. Transparency level, single or infinite repetition also can be assigned.

* Video clip
A video clip can be resized and rotated arbitrary. Transparency level, single or infinite repetition also can be assigned. The audio stream of the added video clip can be superimposed over the original files one, and its volume level can be preset as well.

* Rectangle/Ellipse
For a rectangle/ellipse one can preset dimensions, color, transparency level, Border color and border width. Besides, a rectangle/ellipse can be stretched along the full frame width or height of a processed file. Starting from version 1.1 it is possible to set corner radius for a rectangle.
