Who it is forA hobbyist or maker with a Raspberry Pi 5 who wants to make explainer videos without a Mac.

The problemThe default Remotion browser and the kokoro voice engine do not install cleanly on ARM Linux with Python 3.13.

The outcomeA rendered explainer MP4 produced on a Raspberry Pi 5, using system Chromium and an ARM-friendly voice engine.

What you need first

  • Claude Code or Codex installed
  • Node 18 or newer
  • ffmpeg (brew install ffmpeg on macOS)
  • Python 3 with edge-tts 7.2.8, numpy, pillow and scipy (kokoro and espeak-ng only for English narration)
  • Several GB of free disk space (about 2 to 3 GB per the README)

Steps

  1. sudo apt install zsh espeak-ng and sudo apt install chromium
  2. export REMOTION_BROWSER_EXECUTABLE=/usr/bin/chromium
  3. pip install piper-tts, download a voice model from github.com/rhasspy/piper, then run TTS_ENGINE=piper PIPER_MODEL=<path-to-model>.onnx python3 scripts/tts_build.py (inferred, check the README)
  4. Follow the topic-to-video steps to scaffold the project and storyboard, then run VER=v1 scripts/render.sh.

Prompt for your agent

On this Raspberry Pi 5 with the anything2explainer repo cloned, set REMOTION_BROWSER_EXECUTABLE to the system Chromium and generate voiceover with TTS_ENGINE=piper, then render a short test video. Verify that the render finishes and produces an MP4 that plays with audio.

Caveat. The README verifies this on a Raspberry Pi 5 with Python 3.13 and says Windows is untested, so expect to troubleshoot other setups.
