The Convert Video & Audio module has the Favorites, Devices and Advanced modes to set an output format for the processed video.

The Advanced mode lets you set an output format and a preset for the format. You can use one of ready-made presets, change an existing preset and use it or create, save and use your own presets. Click the Advanced tab to switch to the Advanced mode for setting the output format.

The upper list provides a set of output formats (read more about formats).The lower list provides a set of ready-made presets for every format. A preset is a set of values automatically assigned to the format.

Presets can be modified, created, saved and added to the lists of existing presets. Click Settings to open the Format Settings dialog window to create or modify presets.

The Video Format Settings window consists of 2 panes: Video stream and Audio stream.
The Video stream pane allows you to set a video codec to compress your video, the size of the output video, frame rate, resize method and resize quality.

Codecs serve two purposes: they tell your computer how to encode (or compress) a video file when you save the file, and they tell your computer how to decode (or play) the file when you open the file. Since the same codec is used for both compressing and playing the file, the choice of which codec to use is extremely important. If the codec you use to compress your file is not installed on the user's computer, your user will not be able to play the video. Learn more and download codecs

Frame rate is the measurement of how many images per second are produced while playing.

Resize methods provides 3 options:

• Stretch: height/size proportions are not kept. The video is stretched to match the screen.
• Letter Box: keeps the height in proportion to the width of video.
• Crop: keeps the height in proportion to the width and crops video to match the size of the screen.

Resize quality provides 2 options:

• Normal (Fast): uses the Nearest Neighbour algorithm of resizing. It replicates the pixels in an image copying the nearest pixels. This is a fast method, but it can produce jagged effects.
• Best (Slow): also known as Bilinear method. It adds pixels by averaging the color values of surrounding pixels and produces better quality of video.

The Audio stream pane allows you to set audio format, sample rate and channels characteristics.
