is "Notepad" a bigco IP project name?

yes, microsoft does hold a trademark for notepad. As litigious as MS is I'm pleasantly surprised they've left notepad++ alone.

Unfortunately anthropic is actively eroding community goodwill in regards to potential IP conflicts:

Cool concept, will try it out! I've had decent results with computer use operating conventional editing tools, but being able to directly edit JSON project files is a solid optimization and opens up a lot of opportunities with things like modular templating.

Thankyou. I am planning to make it opencode friendly too.. I think that would openup versatality and more experiments..;)

This is pretty dang cool but I guess I was hoping to see some very clever use of vision and maybe waveform analysis to give the model "eyes and ears" to edit audio and video. V2

yup but I had Premier Pro and Palmier Pro in mind while making it, hence the UI.;)

This looks great, will try it out. I had a crazy idea of doing a full agentic demo video narration and cutting, so might try your tool with some tweaks.

You should strongly consider using Mediabunny to do all of the rendering client-side!

I couldn't find a skill in your project that would help integrate mediabunny. The docs and examples look like they could really help. Having good example coverage allows agents to pickup libraries easily.

Just point the agent at the docs, it'll understand them quickly. Mediabunny also has many examples and even a dedicated LLM page.

Absolutely, in fact just give it clips, voice and a reference video(optional), command it and wait untill it finishes..

Love that the timeline is just JSON and the UI hot-reloads. Agents and humans on the same edit is the interesting part.

Yeah I'm sure you need fable for the heavy reasoning task of editing tiktoks

My impression was that they made this editor with Fable, and its JSON project structure would only serve well for manipulation by lesser models.

I have no use for this, however I am stunned by the simple and effective solution of using json+sse instead of an API to allow agent interaction Amazing work

You should have a hosted site for this - It is entirely frontend - right?

almost! the editor/compositor is fully browser side, but the server is doing real work: project.json lives on disk (thats the whole point, any agent or script can edit it and fs.watch + sse hot reloads the ui), plus ffmpeg for the final export encode. so it needs the local server for the actual workflow.

a hosted demo mode is a good idea though, project in localstorage + sample footage + mediarecorder export would let people feel the editor without cloning. the one thing it cant show is the main trick, watching an external agent rebuild your timeline live, since theres no local file for it to edit. might do a stripped demo build if theres interest

I have little experience with video editing; a tool like this might be an ideal path to learn more. Thanks for creating and publishing it and sharing here!

oh, I read fable as a story, fable cut meaning you can stitch up stories which is a form of storytelling, so quite fitting for video editor

Since people like an unrelated product, you thought it would be good marketing to jack the brand? Maybe I should start calling my B2B SaaS products Salesforce too!

That’s just how some humans write. These words didn’t come from an LLM vacuum.

>That’s just how some humans write.

Sure, but we can't handwave away every observation about LLM output with "(some of) the original training corpora came from humans". Qualitatively, the vibes are off™.
