{"slug": "show-hn-instantvideos-org-short-documentaries-in-30-seconds", "title": "Show HN: InstantVideos.org – short documentaries in ~30 seconds", "summary": "A developer built InstantVideos.org, a system that generates short documentaries in about 30 seconds using AI models including GLM-5.2, Nano Banana 2 Lite, and gpt-4o-mini-tts, with costs around 25 cents per video. The project demonstrates the potential for on-demand AI video generation in narrow domains.", "body_md": "Hiya! So I've been playing around with having Claude make videos for a bit now even had some success posting the results to TikTok (and setup a whole pipeline so Claude can generate and post autonomously). With the release of Nano Banana 2 Lite, I was curious show fast I could make the generation, so last night I gave it a whirl and got down to around 30s for short-form video.\n\nIt uses GLM-5.2 fast via Fireworks to generate the scripts and image prompts and, like I said, Nano Banana 2 Lite for the images, gpt-4o-mini-tts for the narration, and ffmpeg to string it all together and add the Ken Burns zoom effect (which still has a shake I haven't been able to get rid of). The video compilation proved to be the blocker once the rest was in place, but I was able to speed that up by putting it on a 64 vCPU EC2.\n\nThe cost might be the most interesting aspect as the short form videos tend to be about 25 cents. Almost 90% of that is the images, which are 3.336 cents a piece. Of course, running the big 64 core EC2 to allow for the creation isn't cheap.\n\nIt seems like on-demand AI video is coming, and I thought this was an interesting demo of how close it might be in at least one narrow video domain.\n\nComments URL: [https://news.ycombinator.com/item?id=48812045](https://news.ycombinator.com/item?id=48812045)\n\nPoints: 18\n\n# Comments: 18", "url": "https://wpnews.pro/news/show-hn-instantvideos-org-short-documentaries-in-30-seconds", "canonical_source": "https://instantvideos.org/", "published_at": "2026-07-06 23:58:38+00:00", "updated_at": "2026-07-07 07:40:46.196002+00:00", "lang": "en", "topics": ["generative-ai", "ai-tools", "ai-products"], "entities": ["InstantVideos.org", "Claude", "Nano Banana 2 Lite", "GLM-5.2", "Fireworks", "gpt-4o-mini-tts", "ffmpeg", "EC2"], "alternates": {"html": "https://wpnews.pro/news/show-hn-instantvideos-org-short-documentaries-in-30-seconds", "markdown": "https://wpnews.pro/news/show-hn-instantvideos-org-short-documentaries-in-30-seconds.md", "text": "https://wpnews.pro/news/show-hn-instantvideos-org-short-documentaries-in-30-seconds.txt", "jsonld": "https://wpnews.pro/news/show-hn-instantvideos-org-short-documentaries-in-30-seconds.jsonld"}}
