## What it is
SwapTube is a C++ framework for programmatically rendering YouTube videos, built on FFMPEG with custom graphics code above the encoding layer. It requires a CUDA or HIP-compatible GPU and supports in-video LaTeX rendering via MicroTeX.

## Use cases
- render animated youtube videos programmatically
- create math explainer videos with latex equations
- generate videos from code instead of a video editor
- render video frames with gpu acceleration
- build custom animation scenes for educational videos

## When to choose
- you want code-driven video generation on linux with an nvidia or amd gpu
- you need in-video latex equation rendering
- you want full low-level control over the render pipeline beyond ffmpeg

## When to avoid
- you need a supported build on macos or windows
- you lack a cuda or hip-compatible gpu
- you want a gui video editor rather than a code framework

## Facets
- artifact type: library
- maturity: active
- function: video-processing, graphics, animation, gpu-computing
- domain: graphics, media, developer-tools
- platform: cpp, cli
- tags: ffmpeg, cuda, hip, youtube-video-rendering, latex-rendering, programmatic-video, 3blue1brown-style, video, linux, gpu
