VirtualDub is a software utility for capturing and processing video. In addition to creating video files, you can use it to compress and edit video and apply special effects. Effects filters for VirtualDub allow you to sharpen images, remove noise and improve color balance. Special effects include standard pincushion, noise and pixilation filters.

VirtualDub was written by Avery Lee, who originally created the utility to compress anime videos. Lee made VirtualDub available as free software, allowing others to copy, reproduce and modify the software. This has made it possible for other users to write code that gives VirtualDub extra functionality, such as special effects and video-enhancing filters in addition to those that are part of the original utility. An exhaustive list of all the effects available for VirtualDub would run into several pages.

Correction

VirtualDub effects for improving videos and correcting problems include color correction, brightness control, sharpening and denoising filters. Denoising filters remove static and noise; sharpening filters define edges and make images clearer. Color correction improves problems with color balance and removes unwanted color tints (called stains). Brightness control effects correct for problems with videos that are too dark or too bright, and can help to reduce flickering. Other filters include effects to remove ghost images or shakiness. Examples include Color Balance and Xsharpen.

Resizing and Shaping

VirtualDub effects allow you to resize videos, making the image larger or smaller, or placing a border around the picture. Other effects let you change the shape of the picture. These can include subtle effects to make image fit the frame more precisely, or special effects that give the image a decorative shape or distort it. Examples are Canvas Size and Border Control.

Noise

You can add noise to a video, or remove it. This can be random noise, generated using an algorithm that changes random pixels in the image. You can also find effects that produce specific kinds of noise -- for example, the MSU Old Cinema filter creates the effect of an old motion picture, while Analog Noise imitates static on a badly-tuned TV. You can also add color stains, lines or ghost images with filters like MSU Noise Generator.

Fades and Motion Effects

Fade effects let you fade in or out between frames of the video, or fade two video streams together. Examples are Fader MMX and Exotic Fade. Effects such as Motion let you create the impression of panning, zooming or rotating. Perspective is a filter which allows you to artificially change the perspective of an image by stretching or skewing it.

Special Color Effects

Special color effects include Halftone, which converts a frame into two colors that you can select, and color-changing filters like Hue Cycle. Color filters can create psychedelic effects; examples include Luminescence Band, which changes the hues of each pixel in a frame based on their luminescence value.
