About
Generate B-roll footage for videos using AI.
What it does
It turns spoken video into a timed edit plan. Whisper transcribes the audio, an OpenAI model chooses stock-search keywords, Pexels supplies matching clips, and MoviePy combines those clips with the original footage.
Why it's ranked here
The concept is easy to understand because the notebook exposes each processing stage and includes linked input and output examples. It is better viewed as an inspectable prototype than a finished production tool, since execution requires manual setup and external services.
What's good
The workflow preserves transcript timing, connects each generated keyword to a specific segment, and automates stock-footage retrieval. A Colab launch badge, tutorial, demo, and example media make the approach easier to test and understand.
Tradeoffs
It requires OpenAI and Pexels credentials, Whisper, FFmpeg, and several Python packages. Clip placement varies because it randomly selects half the keywords. Search quality is narrow because it takes the first Pexels video and first listed video file.
How to use it well
It suits developers prototyping automated B-roll for spoken, short-form videos in a notebook. Use it as a readable pipeline to modify and validate manually. It does not replace a packaged editor, a complete text-to-video system, or a documented production API.
Technical notes+
AI_Broll.ipynb is the implementation surface. It installs Whisper from GitHub plus pytube, openai, and moviepy; downloads a YouTube source; invokes FFmpeg for audio extraction; transcribes with Whisper's medium model; groups transcript segments in batches of 20; asks gpt-4o for JSON keyword mappings; queries the Pexels video search endpoint; randomly annotates 50 percent of segments; and begins composition with MoviePy. API keys are placeholder constants in the notebook. README.md provides example input, output, demo, tutorial, and adjacent API links. LICENSE contains the MIT terms.
