Now we apply the above rules to a distribution ready DCP in the way outlined below. With the process below, the OV DCP can be used for broad distribution, as the timed text can be translated into any required language because there is no burnt in subtitles on the picture track.
| Picture Track | No burnt-in subs/text |
|---|---|
| Sound Track | 5.1 + Audio Description |
| Timed-text Track 1 | Captions, tagged as Closed Captions (CCAP) so they are available to Closed Caption devices in the cinema. |
| Timed-text Track 2 (If required) | Forced Narrative Subtitles tagged as Open Subtitles (OSUB) so they display on-screen. |
Picture Track = Referencing OV
Sound Track = Referencing OV
Timed-text Track 1 = Captions, tagged as OSUB so that they display on screen.
<aside> ⚠️ Its important that you tag the forced narrative, and open captions as OSUB (which is counterintuitive) because this is the tagging that makes the projectors display the text on-screen. The other tagging options do not always work, so OSUB is the safest tag to use when you want something to show up on screen.
