Kuwedzera Captions.AI kune CapCut, Submagic, Opus Clip, Captions.AI

CapCut's auto-captions are free and good, but you need the CapCut editor installed and you can't batch them. Submagic is $20/mo for unlimited. Opus Clip is $30/mo for long-form → short-form with auto-captions bundled. Captions.AI (App Store) is $10/mo. This tool runs Whisper large-v3 + an ffmpeg ASS karaoke burn-in — the same two primitives all the paid tools use — inside your token pool. For one-offs and batch social exports, it's the fastest path.

AI Caption Generator - FAQ

Inopisa viral-style captions kune chero video neword-by-word karaoke-timing animation. Zvinoenderana ne / video / subtitle /: subtitle inoburitsa SRT / VTT sidecar mafaera ayo vatambi vanochinja on / off. Caption inogara ichipisa, style-first, uye inogadzirirwa TikTok / Reels / Shorts uko captions inofanirwa kuiswa muhardcoded kune yega yega frame.

Zvitanhatu: (1) bvisa mono 16kHz audio kubva pavideo yako, (2) nyora ne Whisper large-v3 ye99-language word timing, (3) gadzira ASS subtitle file neword-level \kf karaoke timing tags, (4) ffmpeg inoravira ASS muzvose frame using libass for clean anti-aliased text.

50 tokens panguva imwe chete (2,000-token minimum). A 30-second clip is ~2,000 tokens (the floor kicks in); a 60-second clip is ~3,000; a 3-minute clip is ~9,000. STT drives most of the cost; the burn-in adds about 25% on top.

Masere: TikTok Neon (yemavara Montserrat, kutsvedza izwi-ne-shoko), YouTube Lowerthird (white Roboto mubhokisi rakajeka), Meme (white Impact neyekumusoro-soro), Podcast (Poppins mubhokisi rakajeka rakasviba), Keynote (Arial Black pakutanga), Cinematic (italic Oswald pasi), uye TED (roboto yakazvimira).

Yeah. The Font dropdown overrides the preset with Impact, Montserrat, Bebas Neue, Arial Black, Oswald, Poppins, Anton, or Roboto. The Highlight Color picker controls the word-by-word highlight (any hex). Position lets you override top / center / bottom regardless of preset.

Yega — 99 zvinyorwa neWhisper. Kuwana otomatiki kunoshanda pa99% yezvinyorwa. Unogona kumanikidza kuchinja chinyorwa kana Whisper ikaona kuti chinyorwa hachina kunyatsoonekwa (zvinowanzoitika pazvinyorwa zvidiki zvisingakwanise kukwira pa5 masekondi kana pazvinyorwa zvine zvinyorwa zvakasiyana-siyana).

Kana pasina mutauro wakataurwa, Whisper inodzokera pasina masegmenti uye isu tinopa "No speech detected" (Hapana mutauro wakaonekwa) matambudziko kuti urege kuparadza mari pabasa risingagone kuitwa.

CapCut imahara, inoshanda pasina kubatana neinternet mushure mekuiswa, uye ine zvinyorwa zvakaomarara zvezvinyorwa - kana CapCut yaive mugadziri wako, shandisa pano. Iyi chirongwa inoita kuti urege kuisa uye inokupa iwe kuwanikwa kwebrowser inoshamwaridzika. Iyo Whisper + libass chain iri iyo imwechete primitive.

Submagic ndi $ 20 / mo yezvinyorwa zvisina muganho nemakumi ezvinyorwa zvemhando. Opus Clip ndi $ 30 / mo nehutachiona hwenguva refu-mufananidzo-ku-mufupi AI kudhonza kusanganisira. Captions.AI ndi $ 10 / mo pafoni. All three use Whisper below; their real value is the style library and clip-detection. For one-offs and smaller volumes AI Caption Generator is free inside your token pool.

Whisper inopa segment-level timestamps — isu tinovapa zvakaenzana segment nguva pamusoro mazwi ayo kuti awane per-word timing. Panguva pfupi-yakataura segments chiyero chinogona kuchinja ne ~ 0.1 masekondi.

Yeah. Pashure export, vaviri subtitled MP4 uye raw.ass faira vari downloadable — edit the.ass mu Aegisub kana iwe uchida pixel-perfect mashoko timing, uyezve re-burn munharaunda ne ffmpeg -vf subtitles=file.ass.

Yeah. POST multipart to /v1/video/caption/ with `file`, `style` (tiktok-neon / youtube-lower / meme / podcast / keynote / cinematic / ted), optional `font`, `highlight_color` (hex), `position`, `language`. Pre-flight: GET /v1/video/caption-quote/?duration=SECS. Snippets at /api/.
