For most video, however, the contrast control is the best way to get black pixels looking nice and dark. It's especially good for video captured titles. This is another way to force "almost black" pixels to become fully black. A good default value is 3 percent.īlack clamp: This filter hard clamps the pixels to fully black when each of the color values are below the specified value. The smoothing range is 0 (no extra smoothness) to 100 (maximum blur). Smoothing a video blurs the pixels together giving smoother and easier to compress video frames. Smoothing percentage increase: This filter allows you to smooth out the video. The contrast range is 0 (no contrast increase) to 127 (maximum increase). This almost always improves compression because it will make "almost black" pixels fully black. Increasing the contrast will make the blacks blacker and the whites whiter. Usually, you should just stick with high-quality mode.Ĭontrast increase: This filter allows you to increase the contrast of a video. The "scaling type" button allows you to choose the method of resizing: high-quality (bi-cubic interpolation - usually the best quality, but sometimes a little fuzzy), medium quality (bi-linear interpolation), and low quality (where the pixels are just dropped or duplicated). If you are both cropping and scaling, the cropping takes place after the resize.įrame Scaling (resizing): The "Width", and "Height" options specify what size to resize the input video frames to. This is a handy tool for making cropped versions of your videos. The numbers are inclusive, so, for example, a start frame of 5 and an end frame of 6 would make a two frame output file.įrame size (cropping): The left, top, "Width", and "Height" options tell the RAD Converter to process only a sub-rectangle of each video frame. Note that even if you use the "Adjust (adds/removes frames) to" feature, these fields use the original, "un-adjusted" frame numbers. The "Start" and "End" fields let you set the beginning and ending frame numbers of the range to convert. You can also specify this value in milliseconds per frame by entering it as a negative number.įrame range: Use this option to control what sections and pieces of the input file are actually processed. The value is specified in frames per second. This option can also be used to make easier-to-playback movies - if you have a 24 fps movie that Bink can't quite keep up with, just use this option to drop it to an easier 12 fps. You would end up with twice as many frames, but they'd playback twice as fast. Say, for example, you had a 15 frames per second animation and you adjusted to 30 frames per second, then each frame of the movie would be processed twice. You'll need to set this option when you compress still images, which have a default rate of 10 frames per second.Īdjust (adds/removes frames) to: You can adjust to a new frame rate by duplicating or removing frames with this option. You can also specify this value in milliseconds per frame by entering it as a negative number. This value is specified in frames per second. The RAD Converter will not duplicate or remove frames during conversion to achieve the new rate. If you are converting an AVI, for example, then unchecking this box would create an audio-only (wave) output file.įorce (no adding or removing) to: Input a new frame rate for the output file with this option (fractional rates are ok). Video settings:Ĭonvert Video: Choose this option if you want to convert the video frames of the input file. To change the default output type, click the "Output type" button next to the output filename and choose the type of output file you'd prefer. Output type: By default, the RAD Converter will create another file of the same type (GIF to GIF, for example). Use the "automatic overwrite" switch when you don't want the converter to ask if you want to overwrite the destination filename. You can use the Browse button to choose from a directory with your mouse. Output file info: Enter the filename that you'd like to compress to in this field. Details on each option are below the screenshot, so you can click on different sections of the screenshot or use the following links to jump right to the help topic you need. To use the converter, highlight the file to change, click on the "Convert a file" button, and the following window will open. Think of it as a Swiss Army Knife for your graphics files! It can cut out portions of an input file, color reduce high color files, createĪVISs from sequentially-numbered single-image files, create super-palettes,Īnd just about any other graphics file manipulation you'll ever need. This simple file conversion is just one of a bunch of tasks that the RAD Converter is good for. The RAD Converter will convert almost any kind of graphics file into any other type of graphics file.
