Subtitles and audio in Kepler

Kepler shows the subtitles and sound tracks your provider sends with each film, episode and channel. This guide shows how to turn on IPTV subtitles in Kepler on a TV, a Fire TV Stick and a phone, choose the audio, change how subtitles look and fix their timing, and find subtitles online when a film has none.

Turn subtitles on

On a Fire TV Stick

Kepler works the same way on a Fire TV Stick as on any TV: while a film plays, press the round button in the middle of the remote, then choose Subtitles.

How tracks are named

Kepler shows each track as the film names it: English, Deutsch, or English 5.1 when the file says so. A track with no name shows its language, and one with neither shows Track 2. Kepler adds nothing of its own, so two tracks of the same language can look alike: try the other one if the first stays blank.

Your choice is remembered. Open the film again and it starts with the same subtitles, and the next film starts with subtitles on in the same language, or off if you turned them off.

Choose the audio track

Like subtitles, your choice is kept for the film, and the next film starts in the same language when it has it.

Change how subtitles look

Open Subtitles, then Sync and style. The card sits at the top so you see each change on the film at once. When no line is on screen, a sample shows: Subtitles look like this.

Row	What it changes	Default
Text size	50% to 200%	100%
Position	How high the lines sit, up to 30% higher	Bottom
Text color	White, light gray, yellow, amber, green, cyan, blue or pink	White
Edges	None, outline, drop shadow, raised or depressed	Outline
Background	A black box behind each line, from none to 100%	None
Font	Standard, condensed, serif or monospace	Standard
Bold	Thicker letters	Off
Formatting from the file	Italics, colours and lines placed at the top, as the subtitle file has them. Off, every line takes your style and sits at the bottom	On

Reset to default puts the look back. It doesn’t change the sync.

The look is one for everything on this device, live channels included. It isn’t shared with your other devices, since a phone and a TV want different sizes, but it is in your backups. Settings has no page for it: Settings › Playback says to change it in the player.

Picture subtitles are different. Found on some copies of Blu-ray discs, they are drawn as they are, and only Position changes them.

Fix subtitles out of sync

When the lines come before or after the voices, open Subtitles, Sync and style, and change Sync, the first row.

• Right (or + on a phone) shows the lines later, Left (or −) earlier.
• Each press is 0.1 seconds. On a TV, hold the key to go faster: half a second a step after a second, then a whole second.
• It changes every subtitle of the film at once, downloaded ones included.

Kepler remembers the sync for that film or episode and brings it back next time. On a live channel, a replay or a recording it starts at 0.0 s each time. To undo it, go back to 0.0 s: Reset to default leaves the sync as it is.

Start every film in your language

In Settings › Playback , under Audio & subtitles:

• Audio language: films and channels start in it when they have it. Default keeps each film’s own track.
• Subtitle language: the subtitles that come on when you turn subtitles on. No preference lets you choose each time.
• Second choice, under each, for films without your first.

Subtitles still start off. Turn them on once in the player and they come on for the next films too, in your language. Choosing a subtitle language turns them off, so you choose when they come on.

A film you have already watched keeps the tracks you chose for it. On a TV, the player’s own settings (hold OK, then Settings) have the same two rows, and a change there applies to what is playing at once. Your languages are shared with the devices you sync.

Find subtitles online

When a film or an episode has no subtitles, or none in your language, Kepler can find them on OpenSubtitles.com.

1. Open Subtitles and choose Find subtitles online. A film without subtitles says This video has no subtitles of its own.

   

2. Kepler searches for this film in your language. The chips at the top change the language; More languages has the rest.

   

3. Choose a result. The first time, sign in with your OpenSubtitles.com account: it is free.

   

4. Kepler downloads the subtitles and turns them on. The film carries on where it was.

   

• The best matches come first: Made for this file, then your languages, Trusted uploader, people before Machine translated or AI translated, then the most downloaded. Hearing impaired files are marked, never hidden.
• OpenSubtitles limits downloads a day; Kepler shows how many you have left. A free account has a small number a day.
• Searching needs no account. Downloading does.
• Kepler keeps the file for that film: opening it again costs no download.
• You can also sign in, or out, in Settings › Playback , under OpenSubtitles. The account stays on this device and isn’t in your backups.

Kepler can’t load a subtitle file of your own. Only OpenSubtitles.com.

Subtitles on live channels Coming in Kepler 1.7

Most channels send no subtitles at all. When one does, hold OK while it plays and choose Subtitles. The tile reads None when the channel has none.

• Kepler reads teletext subtitles, in each language’s own letters, and DVB subtitles.
• Your choice carries over: the next channel starts with subtitles on in the same language, and the same goes for the audio. Your languages in Settings come first.
• Kepler has no teletext page viewer: only subtitle pages are shown.

Surround sound

Kepler sends Dolby Digital (AC3), Dolby Digital Plus (E-AC3, Atmos included), DTS and TrueHD sound to your TV, soundbar or receiver as it is, when they say they accept it. There is no setting for it. When they don’t, Kepler plays the sound itself, so AC3, E-AC3, DTS and TrueHD films play with sound even on a TV without a decoder for them. AC-4 sound is the exception: it needs the TV’s own decoder.

Kepler has no setting for an audio delay.

What is free and what needs Kepler Pro

Choosing subtitles and the audio track, their look and their sync are free. Playing films and episodes is part of Kepler Pro, and so are your audio and subtitle languages and finding subtitles online. The 30-day trial on Google Play includes them. See Kepler Pro.
