You can locate Project Settings on top of the interface.
It’s the fourth button from your left.
Under the Project Settings window, you can choose your project title.
Then you set the target size of your DVD. The default is 4.3GB. You can also select DVD DL (Dual Layer) which is set at 7.9GB.
You can also set the encoder priority.
If you choose high, the encoding process will take longer. If you have good quality video source files, then you can choose the normal encoding mode.
Under the Audio mode, you can set the volume modification. Default is at 100%. Default channel count and bitrate are set at Auto. In most instances it would be wise to stick to the default settings.
Under the Burning option, you can choose Create ISO image or Burn Project to Disc option. Choose the latter option if you want your video to be authored to DVD after the encoding process.
After you have finalized your settings, you could do well to save your project.
