Subtitles Are About Comprehension, Not Just Words on Screen

Subtitles are how many viewers actually follow a story: in a language they read better than the one spoken, with hearing loss, or on a phone with the sound off. On Vodlix, subtitle tracks are attached to each title and chosen from the player's Subtitles/CC menu on the web and on phones, so one video serves every audience. For an OTT service that means wider reach and a more accessible catalogue, without producing a second version of anything.

SRT and VTT Subtitle Support

Each subtitle track is a file you attach on the title's Subtitles tab: pick an SRT or VTT file, choose its language from a list of more than 200 languages and regional variants, and upload. SRT is the format most subtitle vendors and editing tools deliver, and VTT is the web's native caption format, so tracks load as they are. Because a track stays a separate file, it can be corrected or replaced later without re-uploading or re-encoding the video.

Multiple Subtitle Tracks per Title

A title carries one subtitle track per language, each uploaded as its own file. The tracks are stitched into the title's HLS stream, and viewers see every one of them in the player's Subtitles/CC menu, next to Off. The title's default track is the one the player starts with, and on a series the player keeps a viewer's choice from one episode to the next. One video, many languages: subtitles are the most cost-effective way to take a catalogue into new markets.


The Watch & Edit tab: the video playing with its subtitle cue on screen, beside the cue editor with the English default track, the cue under the playhead, 0.1-second nudges, Start and End here, Sync all cues, and a cue flagged too fast at 30 characters per second

Fix Subtitle Text and Timing While You Watch

The title editor's Watch & Edit tab plays the video beside its subtitle cues. Choose a track and the cue under the playhead is ready to edit: correct the words, nudge it by a tenth of a second, or set its start and end where the line is spoken. If a whole track runs early or late, Sync all moves every cue at once, and Shift from here fixes a track that drifts halfway through. Each cue shows its duration and reading speed, lines too fast to read are flagged, and Previous version restores the track as it was before the last save.

Closed Captions and Subtitles

Subtitles carry the dialogue; closed captions also describe what is heard, such as a device humming or a phone ringing, for viewers who are deaf or hard of hearing. A caption file uploads like any other track, so captions and translated subtitles sit side by side in the same menu. Viewers then set the look they read best in the player's caption Options: font family, colour, size and opacity, background colour and opacity, and character edge style, with Reset to default one tap away.

How many subtitle languages does Vodlix support?
The language list on a title's Subtitles tab covers more than 200 languages and regional variants. Each track is uploaded as its own file, and viewers choose from every attached track in the player's Subtitles/CC menu.
Which caption formats does Vodlix accept?
Vodlix accepts SRT and VTT subtitle files, so tracks from any subtitle vendor or editing tool load directly onto a title.
Which subtitle track plays first on Vodlix?
The title's default track. The player selects it when playback starts, and viewers can switch to any other track, or turn subtitles off, from the Subtitles/CC menu. On a series, the player keeps the viewer's choice from one episode to the next.
Can subtitles be updated after a video is published?
Yes. A subtitle track is a separate SRT or VTT file, so you can replace it at any time, or fix its text and timing on the title's Watch & Edit tab, without re-uploading or re-encoding the video.
Can viewers switch subtitle tracks while watching?
Yes. Viewers pick any attached track, or Off, from the player's Subtitles/CC menu, and can change the caption font, colour, size and background under Options.
