It's one half of a two-context problem: the same viewer watches muted on a train and with earbuds in at home, and a video ships into both without knowing which one it'll land in. Burned-in captions solve the muted half by making sure nothing is lost with the sound off. Sound-on strategy is the other half — making sure something is actually gained when a viewer does have it on, rather than the video being identical either way.
Native-audio generation makes this more achievable than it used to be, because dialogue, effects and ambience come out of the same generation as the picture rather than being bolted on afterward in a separate pass — a beat can land on the audio because both were generated to agree with each other from the start.
The two halves aren't in tension so much as sequenced: build the muted version first since it has to work for the largest share of a feed audience, then layer the sound-on reward on top, rather than writing a voiceover-dependent script and hoping captions can rescue it later.
In practice
- Design the muted version first — captions, on-screen text, visual pacing — then add what sound-on viewers specifically gain on top of it.
- Use trending or native audio where a platform's algorithm favours it, rather than an original score alone, when discovery matters more than a distinctive score.
- Test with sound off before shipping, even for content meant to be watched with sound on — most of the audience will still see it muted first.

The mistake to avoid
Writing a voiceover-carried script and treating captions as the fix for muted viewing. A caption track transcribes what was said; it doesn't recreate the pacing a visual-first cut would have had without the voiceover propping it up.

Burned-in captions
Burned-in captions are subtitles rendered into the video's pixels, so they cannot be switched off, restyled by the player, or lost when the file is re-uploaded somewhere else.
Native audio
Native audio means a video model generates its own soundtrack — dialogue, effects, ambience — in the same pass as the picture, rather than leaving you a silent clip.
Hook rate
Hook rate is the share of people shown a video who are still watching a few seconds in — the number that grades the opening, not the edit behind it.
Spark Ads
Spark Ads is TikTok's ad format for putting budget behind a post that already exists — yours or a creator's, with their authorization — so the paid version keeps the post's real likes, comments and shares instead of starting from zero.
Whitelisting
Whitelisting is a brand running paid ads directly through a creator's own handle — with the creator's permission — so the ad shows the creator's name and profile instead of the brand's.
