Show HN: Cartoon Studio – an open-source desktop app for making 2D cartoon shows

The basic flow is: place SVG characters on a scene, write dialogue, pick voices, and render to MP4. It handles word timestamps, mouth cues, and lip-sync automatically.

This started as me playing around with Jellypod's Speech SDK and HeyGen's HyperFrames. I wanted a small tool that could go from script to video without a big animation pipeline and next thing I knew I was trying to create my own South Park style show and here we are. :D

A few details:

- desktop app built with Electron

- supports multiple TTS providers through Jellypod's Speech SDK

- renders via HyperFrames

- lets you upload or generate characters and backdrop scenes

- includes default characters/scenes so you can try it quickly

- open source

It runs from source today. AI features use bring-your-own API keys, but the app itself is fully inspectable and local-first in the sense that there’s no hosted backend or telemetry.

Here are some fun examples of the the types of videos you can create:
