Project Details

Various projects using video on the web need to create innovative and non-standard effects to transform the video, for example, applying filters, altering the video, using 2D and 3D effects, etc. This project will create a library that provides some commonly needed effects (e.g., colour filters, tilt shifting, etc.). This project will overlap and support the HTML5/Video Comic Book project. The follow is a list of Candy effects:

• Normal - Displays the original video used in the <video> tag
• Comic -Darkens the dark, lightens the light, makes it look cartoony
• Grayscale -Black and white effect
• Sepia -Dark brown grey color filter
• Green Screen – Replaces green screen background for an image
• Rotate – Flips the video horizontally, and/or vertically
• Negative -Turns positive RGB video colors into negative RGB
• Bright – Control brightness and darkness of video
• Emboss – Video is molded or carved in relief
• Blur – Defocus on video
• RGB Filter – Manually add/subtract to RGB values
• Modulate – varies the brightness of an image’s pixels in a periodic way. It can be used add “Venitian blind”, “scanline” or “mesh” type effects.
• Pixelate – transforms an image into a grid of uniformly colored rectangles. So named because it simulates increasing the size of pixels in the image.
• Pointillize - Small, distinct dots of pure color that are applied in patterns to form the video
• Divide - Divides the video into smaller videos
• Multichannel - Allows user to mini video and position it on top the original video
• Xray - Black and white effect mixed with the negative effect
• OldTV - Black and white video with some noise
• Noise - Random variation of brightness or color information in the video
