1-2 min video doesn't feel sufficient. Alternatively, a few screenshots uploaded to chatgpt would give the same idea.

Fair - the video could be expanded to be way bigger (1000s of posts)

I found 1-2 minutes was decent (30+ sample size on average), and a tradeoff for convenience. Background sampling would be ideal but privacy concerns and technical limitations (especially on mobile devices)
