On tab “File”, click on “Add” and select file to be converted to add it to list.

Click on “Convert / Save” button.

Under the “Profile” field, select the desired codec profile (e.g. H.264 + MP3 (MP4))

Click on “Browse” on “Destination file” field.

Click on “Start”.

Click on “Play” and wait until it is completed.
