How to Turn Your Podcast into Short Videos — A Complete Guide
Convert podcast audio into vertical short videos for TikTok and YouTube Shorts — full AI pipeline specs, credit costs, a decision table to the right deep-dive article, and honest guidance on when this workflow doesn't fit.
Converting podcast audio into short videos takes three steps: clip selection → visual generation → FFmpeg composition. This guide covers the full pipeline with real specs, credit costs, and a decision table pointing you to the right deep-dive article for your specific needs.
TL;DR
- Input: MP3/WAV/M4A (≤200 MB and up to 90 minutes) or a podcast RSS feed URL
- AI surfaces up to 5 clip candidates with viral scores
- 4 visual styles: sketchnote / cinematic / flat_graphic / manga
- Output: 1080×1920 9:16 MP4, subtitle position Top/Bottom selectable
- Free plan: 50 credits/month — enough to test the full workflow end-to-end
Why Podcasts Need Short Video
Audio content is deep, but discoverability is hard. Short video algorithms actively surface content to non-followers, making vertical clips an efficient acquisition channel for new listeners. The key advantage for podcasters: you already have the raw material.
Which Article Should You Read? — Decision Table
| Your situation | Start here |
|---|---|
| "I want to go from MP3 to a finished video right now" | Audio-Only Podcast to Short Video |
| "I want to process multiple RSS episodes in bulk" | Podcast RSS to Shorts and Articles |
| "I want to understand the faceless video strategy first" | What Are Faceless Videos? |
Step 1: Upload Your Audio
Accepted input:
- File: MP3 / WAV / M4A — maximum 200 MB and 90 minutes
- RSS: paste a feed URL → get up to 100 episodes listed (episodes over 90 minutes are auto-excluded)
Step 2: STT Transcription + Clip Analysis — 5 Credits
After upload, Google Cloud Speech-to-Text v2 (model: chirp, word-level timestamps) transcribes the full audio. Then Gemini 3 Flash analyzes the transcript and returns up to 5 clip candidates, each containing:
| Field | Description |
|---|---|
viralScore | Virality score (0–100) |
reason | Why this clip works |
start / end | Timestamps in seconds |
hookText | Opening hook line (reuse for subtitles or captions) |
recommendedStyle | Suggested visual style |
Step 3: Visual Generation — 5 or 15 Credits
Gemini 3 Flash Image generates still images based on each clip's text content. Choose from 4 styles:
| Style | Look | Best for |
|---|---|---|
| sketchnote | Hand-drawn illustration | Educational, how-to |
| cinematic | Film-like, atmospheric | Travel, storytelling, documentary |
| flat_graphic | Clean vector design | Business, tech, data |
| manga | Comic-panel style | Entertainment, narrative |
Step 4: Video Generation — 0 Credits
FFmpeg composites the final video to these specs:
| Spec | Value |
|---|---|
| Resolution | 1080 × 1920 (9:16) |
| Codec | H.264 / AAC |
| Subtitles | ASS format, Top or Bottom position |
| Video mode | images / waveform / icon |
| Output | MP4 (download) |
