Transform diverse inputs (YouTube videos/audio, existing Suno songs, raw lyrics, audio files, or conversational ideas) into highly optimized Suno V5 custom song generation prompts with intelligent character optimization (5000 lyrics, 1000 style limits), proven metatag reliability, V5-enhanced emotion tags, and template-based best practices. Use when user wants to create music with Suno, provides content for song generation, or needs help crafting effective V5 prompts.
Transform any input into optimized, copy-paste ready prompts for suno.com/create using Suno V5's advanced capabilities and proven success patterns.
Model: Suno V5 (chirp-crow) - Released September 2025 Goal: Generate copy-paste Suno V5 prompts with 90%+ success rate
Core Approach: Template-based generation with quality-focused optimization
Key Principle: Generate immediately, refine iteratively (not question-heavy)
V5 Character Limits:
Activate when the user:
Keywords: suno, song, music generation, lyrics, create music, generate song, song prompt
Input Detection → Template Matching → Prompt Building →
3 Variations → Copy-Paste Ready Output
Time to First Output: <15 seconds (simple inputs)
When user provides a YouTube URL (music video, audio, tutorial):
Process:
Validate URL and check yt-dlp availability:
# Check installation
which yt-dlp || command -v yt-dlp
# If not installed (macOS):
brew install yt-dlp
# If not installed (Linux):
pip3 install yt-dlp
Extract transcript:
# Get video title for file naming
VIDEO_TITLE=$(yt-dlp --print "%(title)s" "$URL" | tr '/' '_' | tr ':' '-' | tr '?' '' | tr '"' '')
# Download auto-generated subtitles
yt-dlp --write-auto-sub --skip-download --sub-langs en --output "temp_transcript" "$URL"
# Clean VTT format (remove duplicates, timestamps, metadata)
python3 -c "
import re
seen = set()
with open('temp_transcript.en.vtt', 'r') as f:
for line in f:
line = line.strip()
if line and not line.startswith('WEBVTT') and not line.startswith('Kind:') and not line.startswith('Language:') and '-->' not in line:
clean = re.sub('<[^>]*>', '', line)
clean = clean.replace('&', '&').replace('>', '>').replace('<', '<')
if clean and clean not in seen:
print(clean)
seen.add(clean)
" > transcript_clean.txt
rm -f temp_transcript.en.vtt
Detect intent:
Handle long transcripts (>1250 chars):
When user provides audio file (.mp3, .wav, .m4a, etc.):
Tiered Approach:
Tier 1 - Metadata Only (no extra dependencies):
# Extract basic info using ffprobe
ffprobe -v quiet -print_format json -show_format "$AUDIO_FILE"
# Gets: duration, bitrate, format
Tier 2 - Simple Analysis (optional, requires pydub):
# Only if user wants energy/tempo estimates
from pydub import AudioSegment
import numpy as np
audio = AudioSegment.from_file(audio_path)
rms_energy = audio.rms # Loudness
# Rough energy classification
if rms_energy > threshold_high:
energy = "High Energy"
elif rms_energy > threshold_medium:
energy = "Medium Energy"
