How does ScribeStamp provide word-level timestamps?

ScribeStamp uses advanced AI speech recognition models to align every spoken word with precise microsecond start and end timestamps. Clicking any word in the transcript jumps directly to that audio playback timestamp.

How does ScribeStamp optimize SRT subtitles for CapCut?

CapCut discards sub-captions exceeding 42 characters or timings longer than 7.0 seconds. ScribeStamp automatically segments raw transcriptions into CapCut-compliant SRT subtitle blocks to prevent character truncation.

What audio formats and languages are supported?

ScribeStamp supports MP3, WAV, M4A, AAC, and MP4 files up to 500 MB. It automatically identifies spoken dialects across over 100 native languages including English, Hindi, Spanish, French, German, Japanese, Chinese, and Arabic.

How many B-roll prompts can ScribeStamp generate per video?

ScribeStamp allows you to set custom prompt counts (up to 100 prompts per audio file) directly in the Studio workspace.

How to Automate AI B-Roll Generation for YouTube & Reels using Audio Scene Prompts (Midjourney, Flux, Runway)

High-retention videos on YouTube, Instagram Reels, and TikTok rely heavily on dynamic B-roll footage every 3 to 5 seconds. However, searching stock footage libraries or manually writing Midjourney prompts for a 10-minute video script can take hours. In this guide, discover how to automate AI B-roll prompt extraction directly from your audio track.

1. The B-Roll Bottleneck in Modern Video Editing

Audience retention drops by up to 65% if a talking-head video does not introduce visual B-roll cuts within the first 15 seconds. Creating contextually relevant B-roll traditionally meant:

Paying expensive monthly fees for generic stock footage sites.
Manually reading scripts to brainstorm visual metaphors.
Spending hours tweaking text prompts in Discord or AI image web generators.

2. How ScribeStamp Extracts Spoken Audio Scenes

ScribeStamp analyzes your transcript's word-level timestamps and feeds key dialogue beats into a high-capacity LLM prompt engine. It automatically identifies visual nouns, action verbs, lighting environments, and camera angles.

3. Midjourney v6 & Flux Prompt Engineering Recipes

ScribeStamp outputs ready-to-copy prompts tailored for Flux and Midjourney v6:

Generated B-Roll Prompt (Timestamp 01:24):

"Cinematic extreme macro shot of glowing neural fiber optic cables carrying light pulses, dark futuristic server room, cyan and emerald green volumetric fog, photorealistic, 8k resolution --ar 16:9 --v 6.0"

4. Animating Still B-Roll with Runway Gen-3 & Luma Dream Machine

Take your generated AI images and feed them into image-to-video generators like Runway Gen-3 Alpha or Luma Dream Machine to generate 5-second cinematic video clips in seconds.

5. Syncing AI B-Roll Back to Video Timelines

Because ScribeStamp provides word-level microsecond timestamps alongside every prompt, you can drag your generated AI B-roll video clips straight to the exact timestamp location on your Premiere Pro, DaVinci, or CapCut timeline!
