Auto Captions adds animated, word-highlighted subtitles to your video automatically — transcribed in 10 languages and fully styled with Google Fonts, colors, and positioning. Prizmad ships it as a built-in tool: upload a video, pick a style, generate.
Auto Captions is Prizmad's automatic subtitling tool for ad and social video. Upload an MP4, MOV, or M4V with clear speech (up to 100 MB), choose the spoken language, and the tool transcribes the audio and burns styled captions directly into the video. Ten transcription languages are supported: English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, Chinese, and Korean.
The styling controls go far beyond a plain subtitle track. You can use any Google Font family, set font size (20–150) and weight (Normal, Bold, Black), pick text and stroke colors, add an optional background bar with adjustable opacity, and position the captions at the top, center, or bottom with a fine Y-offset. Captions are chunked at 1–12 words per subtitle, and the animation switch adds a bounce-style entrance with karaoke word highlighting — the currently spoken word lights up in your chosen highlight color, the caption style you see everywhere in top-performing TikTok and Reels ads.
On Prizmad, Auto Captions uses the same token balance as AI image generation, avatars, video, , and music. Generate a UGC-style ad or on the same account, then caption it here without exporting to a separate editor — one balance, one library, full commercial rights.
Word-by-word highlighted captions keep sound-off viewers following the hook and the pitch — essential for paid social where most playback is muted.
Caption avatar videos generated on Prizmad so the script lands even without audio, using brand fonts and colors.
Burned-in captions make feature walkthroughs and how-to clips usable in feeds, on product pages, and in marketplaces.
Caption Spanish, French, German, Japanese, and other language versions of your ads with the same styled look across markets.
Give Reels, Shorts, and TikToks the polished animated-caption look without a video editor or manual transcription.
Transcribes English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, Chinese, and Korean speech — you just pick the spoken language.
The active spoken word lights up in a separate highlight color — the attention-holding caption style used across short-form ads.
A bounce-style entrance animation (on by default) makes each caption pop in with the speech instead of statically appearing.
Any Google Font family, font size 20–150, Normal/Bold/Black weights, 10 text colors, and stroke width and color for readability on busy footage.
Top, center, or bottom placement with a -200 to +200 pixel Y-offset, so captions clear platform UI elements and product shots.
Set 1–12 words per subtitle and add an optional colored background bar with adjustable opacity for maximum legibility.
Upload your video — MP4, MOV, or M4V up to 100 MB, with clear speech audio. This can be a raw UGC clip, an avatar video, or any ad cut.
Select the spoken language from the 10 supported options so the transcription is accurate.
Set your typography: a Google Font name (Montserrat is the default), font size, and weight. Bold or Black weights at larger sizes read best on mobile.
Pick your colors — text color, highlight color for the active spoken word, and (in Advanced settings) stroke color and width for contrast on busy backgrounds.
Choose the position (top, center, or bottom), fine-tune the Y-offset if needed, and set words per subtitle — the default of 3 keeps captions punchy and easy to follow.
Leave Animated captions on for the bounce entrance and karaoke highlighting, or switch it off for static captions, then click Generate. The captioned video typically renders in about 2–6 minutes.
Auto Captions costs 1 token per run — transcription, styling, animation, and rendering included. Tokens come from your token balance.
Auto Captions is unlocked on the same token balance you use for AI images, avatars, video, and voiceover — no separate captioning account, no per-minute editor fees.
If your tokens run dry mid-campaign, buy a one-off top-up directly from the top-up page. Captioned videos stay yours with full commercial rights.
It's available to any account with enough tokens rather than offered as a standalone free tool. Each captioning run costs 1 token from your token balance — one of the lowest-cost tools on the platform.
1 token per video, covering transcription, styling, animation, and the final render. There's no per-minute editor fee and no separate billing — it draws from the same token balance as every other Prizmad tool.
Yes. Videos you caption on Prizmad are yours to use commercially — in paid ads, on landing pages, and across social — provided you hold the rights to the source video you upload.
Ten transcription languages: English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, Chinese, and Korean. You select the spoken language before generating so the transcription matches the audio.
The captions are rendered into the output video — the result is a finished MP4-style clip with styled subtitles baked in, ready to upload to ad platforms. Set your font, colors, position, and words-per-subtitle before generating.
With Animated captions enabled (the default), each caption enters with a bounce animation and the currently spoken word is highlighted in your chosen color — orange by default, with nine other options. It's the caption style associated with high-retention short-form ads.
MP4, MOV, or M4V files up to 100 MB, with clear speech audio — the transcription is only as good as the audio. Rendering typically takes about 2–6 minutes.
Both live in Prizmad's Captions category. Auto Captions gives you granular manual styling — any Google Font, exact colors, stroke, background, position, words per subtitle, and karaoke animation — at 1 token per video. VEED Subtitles works from preset style templates and adds options like subtitle translation. Try Auto Captions when you want full control over the look.
