Create a Preset
Use this simple form to create a new preset for your device and install it via the File -> Install device preset menu item in Arista Transcoder.
Some values have been pre-filled for you with safe defaults, but if you know that your device limits these values you should change them. For example, you could limit your iPhone's video dimensions to be a maximum of 640 wide and 480 tall.
Note that this is a simplified interface to Arista Transcoder's device preset system. For more complex changes you'll need to open the preset's JSON file in a text editor.
When finished, click create to download the preset file.
