Kigo offers three kinds of subtitles encoding ways to meet users' needs for playing video on different media players or devices. The mode "External subtitles" will help you save subtitles as separate files.

"Internal subtitles" will make the subtitles be built into the output video, which will allow you to save multiple languages subtitles and switch as needed while playing the video on some players like VLC Media player.

If your media players or devices don't provide subtitle options or support to add subtitle, "Hardcode subtitles" is a great option to help you make the subtitles be burned onto your video. But please note that you can save only one language into the video at a time.

There are three options for video quality (High / Medium / Low) in the settings window, enabling you to download videos with different output quality according to your devices. At preset, you can only download up to 1080p videos.
