Video Effects Every object can have one or more effects applied to it. - Black and White - When applied, the image will appear black and white. Also known as gray-scale. For partially desaturating colors, use the Saturation effect instead.
- Sepia - Tints the image with a sepia color.
- Negative - Every color is replaced with its negative color, like a film negative.
- Noise - Random pixels are drawn on top of the image. The higher the intensity, the more noise is added, and less of the original image is visible.
- Brightness - Applies brightness, contrast, and/or gamma to the image.
For brightness: Negative values give a darker image. Positive values give a brighter image. For contrast: Negative values give lower contrast, causing dark areas to appear brighter and bright areas to appear darker. Positive values give higher contrast, causing dark areas to appear darker and bright areas to appear brighter. For gamma: The value specifies non-linear gamma correction. Values less than 1 give a darker image. Values greater than 1 give a brighter image.
- Edge Detection - Finds and highlights the edges of objects in the frame.
- Posterize - Reduces the apparent number of colors in the image, changing gradients into flat areas of color.
- Pixelate - The higher the coarseness value, the larger the size of the blocks used to render the image, and the lower the resolution appears.
- Blur / Sharpen - Negative values cause edges in the image to be sharpened. Positive values cause the image to be smoothed. Also known as blurred or softened.
- Saturation - Negative values cause the colors to be desaturated, where the minimum value gives a black and white image. Positive values cause the colors to be over saturated.
- Hue - Shifts the hue of every color in the image by the specified percentage, giving unnatural colors.
- Temperature - Used to correct colors in video or images taken with incorrect white balance. Negative values make the image cooler. Positive values make the image warmer.
- Tint - Tints the image with an RGBA (red / green / blue / alpha) color value. The Intensity slider changes the alpha.
- Two-Tone - The brightest half of the pixels are converted to one color while all the rest are converted to another color.
- Tiles - Makes the image look like it is made of rectangular tiles. The number of tiles and the spacing between tiles can be changed.
- Green Screen - Also known as "green screen" or "chroma keying".
Green screen is the process of removing a selected color from an image. For example, to show an actor standing in front of a computer generated background, the footage of the actor can be shot against a green screen. The background can then be removed with the green screen video effect to reveal another clip underneath which will provide the new background. - Special Effects: (Balloon, Snow and Snowflakes)
- Balloon - Add balloons into an image. Color and number of balloons per second can be set. Other parameters include screen time, wobble amplitude and frequency, scale and opacity.
- Snow - Add snow into an image. Parameters like number of snow per second, screen time, distance variance, fuzziness and glowiness can be set.
- Snowflakes - Add snowflakes into an image. Parameters like number of snowflakes per second, screen time, sway frequency and amplitude, spin speed and variance, glowiness and distance variance can be set.
Sound Effects
- Amplify - Increases the loudness (or volume levels) of the selected object. The volume is entered in percent (100 being no change, 50 being -6dB softer or 200 being +6dB louder).
- Chorus - Makes one voice or one instrument sound like 3 voices or instruments by playing the original with variably delayed and slightly pitch changed copies of the original.
- Compressor - A Dynamic Range Compressor limits the volume levels of a sound recording so that it stays within a certain loudness range.
An example of where it is used is in TV broadcasting, where it ensures that the volume levels of ads are perceived as being louder than the television program itself (without any change in the actual broadcast volume). The "Threshold" setting works by detecting when the sound recording volume exceeds a defined decibel level. It then gradually attenuates the sound to bring it down below the dB level, and does it in such a way that the listener will not be aware the attenuation is occurring. The "Ratio" setting limits the amount the volume level of the recording increases at any one time. If, for example, you wanted the volume levels of a recording to only increase by at most 1/4 of the amount they would normally increase, then this would correspond to a Ratio of 4:1. So if the recording volume level increased by 8dB, then you would only hear a 2dB volume increase. The "Limit" setting defines at what maximum decibel level the sound recording will be allowed to rise up to. So if, for example, the Limit was set to 0dB, then you will never hear the volume level of the recording get louder than 0dB. The Limit setting has similarities to the Threshold setting, but the main difference is that the Threshold does allow sounds to go above the defined decibel level (for a short time), whereas the Limit does not. You will find that the minimum Limit volume you can set is the same as the maximum Threshold value. This basically means that, in any situation, the sound will start to attenuate at the threshold level, but will never be heard louder than the limit. - Distortion - Adds distortion to sound. Degree of distortion is measured in percents. Top Line Level determines the level where the distortion kicks in.
- Echo - Repeat the sound after a specified short time.
- Flanger - Similar to the phaser, except that the delay is slowly modulated over time. You specify the starting delay time, the frequency of modulation, the depth of modulation and the wet dry gain (100% for wet, 0% for dry).
- High Pass - A high-pass filter (sometimes called a low cut filter) removes all low frequencies below a specified Hz. This is useful if you want to make your recording sound 'clearer' or less 'muddy'. It is very usual to use a high-pass filter of about 300Hz on all voice recordings to improve intelligibility.
- Reverb - Reverb is many small reflections of the sound that come after a set time. It usually occurs when someone is speaking in a room, hall etc. More reverb is called wet, no reverb is called dry.
- Pan - Fades the audio between the left and right channels.
