ArtBox

ArtBox is a tool set for handling multimedia files.

• Repository: https://github.com/mediatoolbox-org/artbox
• License: BSD-3-Clause

Features

• Generate project configurations from presentation files (PDF + PPTX)
• Render narrated slide decks to MP4 from a YAML project file
• Convert text to speech and speech to text
• Download YouTube videos and captions
• Process audio and video files from the CLI

Setup

ArtBox depends on system packages that may vary by platform. A conda or mamba environment is recommended:

$ mamba create --name artbox "python>=3.10,<3.14" "pygobject>=3.44.1,<3.49" pip
$ conda activate artbox
$ pip install artbox

Examples

For the following examples, create a temporary folder:

$ mkdir /tmp/artbox

Generate a project configuration

If you exported your presentation slides as PDF and speaker notes as PPTX, you can scaffold a project file automatically:

$ artbox init \
    --source-pdf /tmp/artbox/presentation.pdf \
    --notes-pptx /tmp/artbox/presentation.pptx \
    --output /tmp/artbox/project.yaml

Then render the project:

$ artbox render --project /tmp/artbox/project.yaml

Convert text to audio

By default, artbox speech uses edge-tts, but you can switch to gtts with --engine gtts.

$ echo "Are you ready to join Link and Zelda in fighting off this unprecedented threat to Hyrule?" > /tmp/artbox/text.md
$ artbox speech from-text \
    --title artbox \
    --input-path /tmp/artbox/text.md \
    --output-path /tmp/artbox/speech.mp3 \
    --engine edge-tts

If you need a different language:

$ echo "Bom dia, mundo!" > /tmp/artbox/text.md
$ artbox speech from-text \
    --title artbox \
    --input-path /tmp/artbox/text.md \
    --output-path /tmp/artbox/speech.mp3 \
    --lang pt

For edge-tts, you can also specify locale, rate, volume, and pitch:

$ echo "Do you want some coffee?" > /tmp/artbox/text.md
$ artbox speech from-text \
    --title artbox \
    --input-path /tmp/artbox/text.md \
    --output-path /tmp/artbox/speech.mp3 \
    --engine edge-tts \
    --lang en-IN \
    --rate +10% \
    --volume -10% \
    --pitch -5Hz

Convert audio to text

ArtBox uses speechrecognition for speech-to-text (currently google engine):

$ artbox speech to-text \
    --input-path /tmp/artbox/speech.mp3 \
    --output-path /tmp/artbox/text-from-speech.md \
    --lang en

Download a YouTube video

$ artbox youtube download \
    --url https://www.youtube.com/watch?v=zw47_q9wbBE \
    --output-path /tmp/artbox/

To request a specific resolution:

$ artbox youtube download \
    --url https://www.youtube.com/watch?v=zw47_q9wbBE \
    --output-path /tmp/artbox/ \
    --resolution 360p

If you encounter bot detection, enable OAuth:

$ artbox youtube download \
    --url https://www.youtube.com/watch?v=zw47_q9wbBE \
    --output-path /tmp/artbox/ \
    --use-oauth

Download YouTube captions

$ artbox youtube cc \
    --url https://www.youtube.com/watch?v=zw47_q9wbBE \
    --output-path /tmp/artbox/cc.txt \
    --lang en \
    --format text

Create a song based on notes

$ echo '["E", "D#", "E", "D#", "E", "B", "D", "C", "A"]' > /tmp/artbox/notes.txt
$ artbox sound notes-to-audio \
  --input-path /tmp/artbox/notes.txt \
  --output-path /tmp/artbox/music.mp3 \
  --duration 2

Generate an audio spectrogram

$ artbox sound spectrogram \
  --input-path /tmp/artbox/music.mp3 \
  --output-path /tmp/artbox/spectrogram.png

Remove audio from a video

$ artbox video remove-audio \
  --input-path "/tmp/artbox/sample.mp4" \
  --output-path /tmp/artbox/video-without-audio.mp4

Extract audio from a video

$ artbox video extract-audio \
  --input-path "/tmp/artbox/sample.mp4" \
  --output-path /tmp/artbox/video-audio.mp3

Get metadata from a video

$ artbox video get-metadata \
  --input-path "/tmp/artbox/sample.mp4" \
  --output-path /tmp/artbox/video-metadata.json

Combine audio and video files

$ artbox video combine-video-and-audio \
  --video-path /tmp/artbox/video-without-audio.mp4 \
  --audio-path /tmp/artbox/video-audio.mp3 \
  --output-path /tmp/artbox/video-combined.mp4
