Filter (none):
This filter will do nothing.

Filter Add grain:
This filter will add random grain. It will randomly modify some pixels color of a certain amount. This will help mimic the film grain of a movie image in a video image.

Filter Blocks:
This filter will replace a block of pixels by one median color.

Filter Chroma Key:
Chroma Key filter will create a black and white mask (Alpha channel) of the images to help composite the images by removing a background made of an almost uniform color like blue or green.

Filter Contrast colors:
Contrast colors filter will create colors from the contrast of the image. This can make strange color effects and help highlight contrast variation.

Filter Dark to Black:
This filter will change dark pixels into real black (R,G,B) = (0,0,0) pixels.

Filter Deinterlace type 1:
This filter will copy one scanline to the next one. This will remove interlacing found in video images but will also result in data lost as data from each other line is ignored.

Filter Deinterlace type 2:
This filter will replace the pixels of the scanline by the average of the 6 nearest pixels from previous and next row. This will remove interlacing found in video images but will also result in data lost as data from each other line is ignored. This filter usually give better results than 'Deinterlace type 1' but is slower.

Filter Deinterlace type 3:
This filter will replace the pixels of the scanline by the average of the 9 nearest pixels from this row, previous and next row. This will remove interlacing found in video images. This filter usually give better results than 'Deinterlace type 2' but is slower.

Filter Detect movement:
This filter will replace the pixels with the difference between one image and the image just before. So if there was no movement, the pixel will be black. Otherwise it will have keep its color.

Filter Euclidian distance map:
This filter will modify the colors according to the Euclidian distance map.

Filter Grayscale:
Grayscale filter will change color image in grayscale image equivalent to black and white movies or TV.

Filter Light intensification:
Light intensification filter will simulate the use of a light intensification device by changing the image to a grayscale image with a light green look and by increasing the bright parts of the image.

Filter Lightning:
Lightning filter will add to the current image a lightning.

Filter Magnifying glass:
This filter simulates the view through a magnifying glass.

Filter Make End as Start:
Make End as Start filter will merge first and last frames to make the video repeat itself seamlessly. This is usefull for background or textures videos. If you merge X images, the final video will be X images shorter.

Filter Mirror:
Mirror filter will mirror the image horizontally or vertically.

Filter Modify colors 1:
This filter will reduce the colors of the image.

Filter Modify colors 2:
This filter will replace the colors of the pixels with other colors in a range.

Filter Modify colors 3:
This filter will shift the colors of the image of a certain amount.

Filter Modify colors 4:
This filter will modify the colors of the pixels of the image according to their luminosity.

Filter Motion Blur:
Motion Blur filter will add to the current image a percentage of previous images to simulate slow camera shutter speed.

Filter Negative image:
This filter will replace the colors of the pixels with the opposite color like in a negative picture.

Filter Persistence:
Persistence filter will add to the current image a shadow image from previous images.

Filter Scrambled like Pay TV type 1:
This filter will scramble the image like a Pay TV show. Each line of the image is rotated a random number of pixels. You can choose a maximum number for the rotation.

Filter Scrambled like Pay TV type 2:
This filter will scramble the image like a Pay TV show. It will permute each line of the frame with another randomly selected among the next X lines.

Filter Waves:
Waves filter will modifiy the image with sinus waves.
