This is the list of video effects available in Kdenlive and its parameters. They are implemented as part of the MLT Framework.

No effect

This is the original image with no effects, to allow comparisons.

Box blur

This effect blur the image.

Brightness

With this one, you can make the video look as if there was less light -- or more of course.

Charcoal

Here you can get a charcoal pencil draw.

Gamma

Here you can change the gamma.

Greyscale

This one will help you publishing on very old TV sets ;-)

Invert

Inverts the colors of the video, you get something like a argentic negative.

Mirror

Here you can mirror half of the image, either horizontaly, verticaly, or following a diagonal. The invert option helps on getting the interesting part of the video mirrored.

Obscure

Allows you to mask a portion of screen with keyframable mosaic effect.

Sepia

Let's make an old fashioned movie : sepia transforms colors in shades of brown. But with Kdenlive, you can control the color output, so this can be shades of any color.

Speed

Allows you to slow down, speed up, reverse play and make stroboscope effect. This effect is available only if Kdenlive was compiled with the latest development version of MLT, taken from its cvs. and clip.

Freeze

Allows you to freeze the clip at, after or before a certain frame. You choose a frame that will be shown for the whole clip, or just a part of it.

This effect is available only since Kdenlive version 0.5.
