contributions: youtube shorts ideas generator from transcript

[bearnithi]

Adds a Week 1–style community notebook that turns a long-form YouTube video into Shorts ideas.

Paste a video URL; the notebook pulls the transcript with youtube-transcript-api, then asks OpenAI (gpt-5) for five Shorts concepts. Each idea includes a description and start/end times from the original transcript so you can jump to the clip.

What it does

1. Install youtube-transcript-api
2. Parse the video ID from a watch?v= URL and fetch the transcript
3. Send the transcript with a system prompt that asks for 5 unique, relevant Shorts ideas as JSON
4. Render the model’s JSON as Markdown

Expected shape per idea:

• idea
• description
• original_transcript_start_time
• original_transcript_end_time

How to run

1. Set OPENAI_API_KEY in the environment
2. Open community-contributions/yt-shorts-ideas-by-bearnithi/shorts.ipynb
3. Run all cells (installs the transcript package)
4. Optional: change video_url in Step 3 to another https://www.youtube.com/watch?v=... link
