Caption Your Podcast in 5 Minutes (2026 Guide).

To caption a podcast, upload the file, let Whisper transcribe every word with a timestamp, drag in/out points around the moment worth clipping, then export a captioned, auto-cropped 9:16 video — the whole pass takes about 5 minutes per clip. One export costs 1 clip credit, a wallet separate from generation credits.

getvivix Caption Studio runs the whole pipeline in one project — transcription, moment-picking, captions, vertical crop, export — with no separate video editor to learn. It pairs with the caption maker and Shorts maker when the same episode needs to go out on more than one platform.

What You Need to Caption a Podcast

Any audio or video file works — MP3, MP4, M4A, or WAV. Caption Studio transcribes the whole file in one pass with OpenAI's Whisper model, which covers 90+ languages and outputs the transcript in that language's own script. Each upload is capped by plan: 10 minutes / 100MB on Standard, 15 minutes / 250MB on Pro, 25 minutes / 500MB on Ultimate — trim the episode down first if it runs longer than that. From there, everything happens inside the same project: no downloading a transcript, editing it in another app, and re-uploading the video.

What's the Right Clip Length?

Sixty to ninety seconds is the safest cross-platform target for a spoken, substantive clip — long enough to hold a real moment, short enough to post anywhere without re-editing. Per-platform data varies more than one number suggests:

Source: Shortimize video-length analysis, checked July 2026. A podcast clip is spoken content, not a trend-format snippet, so 60-90 seconds sits inside the better-performing band on every platform without landing in YouTube's weak 30-45 second middle. YouTube itself now allows Shorts up to three minutes, up from the original 60-second cap (YouTube Help), but shorter still wins on average. Pick the moment before the length — a strong claim, a laugh, or a specific number is what makes a viewer stop scrolling, not the exact second count.

Which Caption Style — and When to Skip This Tool

Caption Studio ships more than twenty caption templates, from plain single-color styles to bold animated ones like MrBeast and Neon Glow. Karaokeis the one built for fast, punchy dialogue — it highlights each word as it's spoken. Export crops to whichever aspect ratio you pick — 9:16 for Shorts/TikTok/Reels, or 16:9, 1:1, and 4:3 for other placements.

This isn't the right tool for every workflow. If you want an algorithm to find the viral moments for you without reading the transcript yourself, this isn't that — you pick the moment. Episodes past the plan length caps above need trimming first, and multi-camera cuts or a full timeline edit belong in a dedicated video editor — bring the finished cut here just for captions and the vertical crop.

How to Caption a Podcast on getvivix

1. Upload the episode — MP3, MP4, M4A, or WAV, up to your plan's length cap.
2. Wait for the transcript, then click any line to jump the playhead there.
3. Drag the in/out handles around a 60-90 second moment.
4. Pick a caption template from the 20+ options, or default to Karaoke for punchy dialogue.
5. Export. Captions burn in and the crop goes to 9:16 in one pass.

Each export costs 1 clip credit — a wallet separate from generation credits. Free signup includes 1 clip credit; Standard, Pro, and Ultimate add 80, 120, and 400 clip credits a month respectively (verified against the live pricing page on July 28, 2026).

FAQ

Can I edit the in/out points after seeing the export?

Yes. Your transcript stays saved in the project — open it again, drag new in/out points, and export again. Each new export costs another clip credit.

Can I add voice-over or B-roll?

Yes. Generate a voice-over with the getvivix voice generator or B-roll with the text-to-video tool, then layer either one under the podcast audio in the same project.

How accurate is the transcription?

Around 95-98% on clear audio. Accuracy drops with heavy background noise, cross-talk, or strong accents — the same limitation any speech-to-text model has. Fix a wrong word by clicking the caption, retyping, and saving; timing stays locked to the audio.

Does it work for non-English podcasts?

Yes. Whisper transcribes 90+ languages and outputs the transcript in that language's own script, so captions come out correct without manual translation.

Captioning a podcast comes down to one file in, one captioned 9:16 clip out, in about 5 minutes — no separate editor, no manual re-crop. Pick the moment with a real hook, keep it to 60-90 seconds, and let the transcript do the finding. Repurposing the same episode into scripted shorts instead of clipped ones?
