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.
Choose location for output file . Default container is .mp4, but you may change it.
Click on “Start”.
Click on “Play” and wait until it is completed.
