Automated Workflow (Mubert API)

Step 1: Sign Up for Mubert API

1. Go to https://mubert.com/api
2. Sign up for free account
3. Get API key (PAT - Personal Access Token)
4. Store API key securely in environment variables or credentials file

Step 2: Generate Background Music

#!/bin/bash
# generate-music.sh

API_KEY="YOUR_MUBERT_API_KEY"
DURATION=46  # seconds (match video duration)
TAGS="corporate,upbeat,educational,instrumental"

# Generate track
curl -X POST https://api-b2b.mubert.com/v2/RecordTrack \
  -H "Content-Type: application/json" \
  -d '{
    "method": "RecordTrack",
    "params": {
      "pat": "'$API_KEY'",
      "duration": '$DURATION',
      "tags": "'$TAGS'",
      "mode": "track"
    }
  }' | jq -r '.data.link' > music_url.txt

# Download MP3
wget -O background-music.mp3 "$(cat music_url.txt)"

Step 3: Add Music to Video with ffmpeg

#!/bin/bash
# add-music-to-video.sh

VIDEO_INPUT="vitamin-b12-deficiency-compliant-FINAL.mp4"
MUSIC_INPUT="background-music.mp3"
VIDEO_OUTPUT="b12-with-music.mp4"

ffmpeg -i "$VIDEO_INPUT" \
  -i "$MUSIC_INPUT" \
  -c:v copy \
  -c:a aac \
  -filter_complex "[1:a]volume=0.3[music];[0:a][music]amix=inputs=2:duration=shortest" \
  -shortest \
  "$VIDEO_OUTPUT"

echo "✅ Video with music created: $VIDEO_OUTPUT"

Audio Volume Notes: - volume=0.3 = 30% music volume (background) - Adjust between 0.2-0.5 depending on narration volume - amix mixes original audio (narration) with background music - duration=shortest ensures music doesn't extend beyond video

Step 4: Post to X (Twitter)

#!/bin/bash
# post-to-x.sh

VIDEO_FILE="b12-with-music.mp4"
POST_TEXT="🎬 NEW VIDEO IS LIVE! 🎬
