QuickTime File Format

neato burrito this one was pretty neat i saw this on blue sky by via user nat suneco dot cat uh which makes sense given their name what if you wanted to make awesome videos and have it be as simple as writing react well now you can with celesta a react like language for building videos So you can build cool visualizations.

It's a code-first video tool, build animated scenes with React and TypeScript, combining video images and text shapes, audio, preview your work in the Celeste desktop app, export it as MP4, MOV, WebM, PNG, JPEG, WebP, yada, yada, yada.

So if you want to do like the, I forget what the three blue, one brown framework is, but it feels like that kind of idea where you want to use code first to generate neat videos.

And their example here was built by Claude Opus.

Now, yesterday, since my Shure MV7 Plus microphone, since my microphone that goes into Logic, which is the version that you're supposed to hear, also goes through QuickTime as well.

into one of the video feeds, whatever happens to the microphone feed then affects both sources or both output, both recorders, the QuickTime, the MOV on my computer and Logic.

And yesterday it failed.

I don't know, halfway through, actually the entire episode, it seemed to be kind of janky.

Gemini 3-1 Pro works best with standard video formats.

MP4, MOV, and AVI files all work well.

The sweet spot seems to be videos between 30 seconds and 2 hours in length.

Shorter than 30 seconds and you're not really taking advantage of the contextual understanding.

this shouldn't be if I'm paying, they are offering AI services that I know how to use.

And this using Terminal to prompt Claude and giving it access to my entire file system now enables me not just to create the video clips, because it takes the JSON, which contains all the information it needs, refers back to the MOV, the video file that I record for this here podcast.

and constructs clips from it, fully edited clips.

Now it does landscape, but that's because I haven't told it to do vertical instead, which if I were to use, this is all possible.

It is a hotkey trigger.

So instead of doing a fully automated folder action, that is like once the MP3 is dropped in here or the MOV is dropped into this folder, trigger this workflow, I don't want that because it can break.

It can...

That's where it starts d-doing stuff, and you're going, "Stop, stop, stop, stop, stop, stop, stop.
