ChatGPT wouldn't do it, Claude wouldn't do it.
Eventually tried Perplexity and it was able to generate notes with correct code snippets from my WordPress course videos. Amazing since it didn't have to invent anything -- just capture everything I said and include the relevant code snippets.
The trick was to create 1 FPS videos with full audio so that it still has access to full video contents and audio but with ~5% of the file size. Worked great.
