Description
Hi HN — I built Cartoon Studio, an open-source desktop app for making simple 2D cartoon scenes and 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. :DA 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 sourceIt 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:https://x.com/deepwhitman/status/2046425875789631701https://x.com/deepwhitman/status/2047040471579697512And the repo:https://github.com/Jellypod-Inc/cartoon-studioHappy to answer questions and appreciate any feedback!

Could you build this?
Yes This is a desktop app wrapping SVG rendering, standard TTS APIs, and existing open-source forced-alignment/phoneme libraries (like Rhubarb) to export video via FFmpeg.
Discussion
5 comments analyzed.
Competitors mentioned: Rhubarb (lip-sync tool), Synfig Studio (animation software), Moho (character animation), Papagayo (lip-sync), Jellypod (text-to-speech)
Concerns raised: Lip-sync quality insufficient for non-forgiving animation styles, Oversimplified mouth representation (two circles vs. viseme sets), Text-to-speech sounds artificial/uncanny valley, Vowel-per-word heuristic may not scale, Misleading 'Studio' branding for limited static character tool
Feature requests: Comprehensive viseme-based lip-sync system, Integration with Synfig Studio, Support for more sophisticated mouth/jaw animation, More natural-sounding speech synthesis
