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

Burns viral-style captions into any video with word-by-word karaoke-timing animation. Different from / video / subtitle /: subtitle outputs SRT / VTT sidecar files that players toggle on / off. Caption inogara ichivharwa, iine hunhu hwekutanga, uye inogadziridzwa kune TikTok / Reels / Shorts uko captions inofanirwa kuve yakaoma-yakavharwa kune yega yega frame.

Zvita mashanu: (1) bvisa mono 16kHz audio kubva kune yako video, (2) nyora ne Whisper large-v3 ye99-language word timing, (3) gadzira ASS subtitle file neword-level \kf karaoke timing tags, (4) ffmpeg inopisa ASS kune yega yega frame ne libass yekugadzirisa anti-aliased text.

50 tokens pasecond (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 inotungamira zhinji yemari; burn-in inowedzera nezve 25% pakutanga.

Masere: TikTok Neon (yemavara Montserrat, kuratidzwa kwezwi neshoko), YouTube Lowerthird (white Roboto mubhokisi rakajeka), Meme (white Impact neyemavara ekumashure), Podcast (Poppins mubhokisi rakaoma rakarukwa), Keynote (Arial Black pakutanga), Cinematic (italic Oswald pasi), uye TED (roboto yakaenzana nechiuno).

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.

Hapana. Kana pasina mutauro wakataurwa, Whisper inokudzosera pasina masegmenti uye isu tinopa "No speech detected" error kuitira kuti urege kuparadza mari pabasa risingagoneke.

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

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.
