Audio Video Effects - Video Gamma Correction Effect

If you see this text then you may need to click here to get the MCMP codec.

Below are videos that demonstrate the Gamma filter. This filter adjusts the intensity of colors in the image by changing the gamma constant that is used to map the intensity values. Intensity values ideally follow a logarithmic progression because the eye perceives changes in intensity as being equal when the ratio of change is equal. For example, we would see a change from 0.1 to 0.2 as being equal to a change from 0.2 to 0.4. Gamma is a standard constant that is used to calculate the progression. This filter can be used during capture for real-time processing, during conversion or during playback to enhance existing media files.

Video Gamma Correction Example

Examples of Types of Applications

Because gamma corrections helps correct variances in brightness when using different hardware, the gamma correction would be useful in any of the following:

• Any application that captures video in conditions that lighting can be different from capture to capture.
• Any application that captures with different types of cameras and/or lens.
• Any application that will play the video back to hardware by various manufacturers.
