Re: Launch HN: Cardboard (YC W26) – Agentic video editor
#22Really impressive work guys! It seems like YC has funded a few companies attacking this but I think you all might have the best approach so far. Behind the scenes is the agent just editing using text/annotated timelines? I feel like the move is probably text for roughcut/narrative, then a vlm for digesting the initial roughcut, then adding broll and fixing timing issues. Feel free to steal my FCP xml generator. https…
happy that you liked our approach! also, i think it's a better idea to just give agent these tools and let it figure out its course of actions than giving it a specific workflow to work on - it seems like the world keeps reminding us the bitter lesson [http://www.incompleteideas.net/IncIdeas/BitterLesson.html] more frequently these days
will definitely check the XML exports, ty :)

#23Wow! congrats on the launch guys. client-side rendering is incredible, really. I saw your product somewhere and have it as an open tab in my chrome for ~2 weeks :D
I also saw another YC company, Mosaic, doing something similar. But your approach of chat-based editing is a lot closer to what I'm building. Shameless plug: I'm also working on a chat-based media processor. https://chatoctopus.com
But you guys are way ahead! will be looking at you for inspiration.

#27Funnily, this was an issue for myself so I built an open source AI video editor - https://github.com/waylonkenning/aidirector Cardboard looks really well polished, well done!
damn that's really cool, you ship fast!

my bad, I didn't test it enough on touch devices. Just pushed a fix, appreciate you flagging it!
