No cameras, no editing timeline, no production crew needed.

No. FlyU.ai handles everything automatically - beat detection, scene composition, transitions, effects, and format optimization. If you can upload a song and pick a style, you can create a professional music video. There is no timeline to scrub, no keyframes to set, and no rendering settings to configure.

FlyU.ai integrates seven leading AI video models - more than any other music video platform. Each model has unique strengths:

• Seedance 2.0 - Best for hyper-realistic human motion, multi-shot narrative coherence, and cinema-grade output.
• HappyHorse - Best for stylized character animation, anime-style visuals, and 7-language lip-sync.
• Kling 3 - Best for 4K 60fps output, photorealistic human performance, and virtual concerts.
• Veo 3 - Best for cinematic photorealism with native audio-visual coherence.
• Sora 2 - Best for Hollywood-grade scene generation and long-form narrative (up to 60 seconds per clip).
• Gemini Omni - Best for multimodal creativity blending text, image, and video inputs.
• Grok 1.5 - Best for narrative-driven visual generation with deep musical understanding.

Not sure which to pick? FlyU.ai automatically recommends the best model based on your chosen visual style and music genre. You can always switch models and re-generate to compare results.

FlyU.ai's proprietary beat-sync engine is what separates us from generic AI video tools. Here is the technical breakdown:

• Spectral Analysis - The engine scans your audio's waveform to detect BPM, individual beats, downbeats, and off-beats across a 60-200 BPM range.
• Structure Recognition - Identifies song sections (intro, verse, chorus, bridge, drop, outro) by analyzing energy contours, frequency distribution, and rhythmic patterns.
• Multi-Layer Sync - The engine maps audio events to three independent visual layers: scene transitions (beat-level), camera movement (energy-level), and effects/particles (accent-level).
• Manual Override - For Pro users, you can set custom beat markers to fine-tune specific moments while letting AI handle the rest.

Pro Mode achieves 99.2% beat-sync accuracy - the highest precision in the market. You can also adjust sync intensity (Low/Medium/High) to match your genre: subtle for ambient, aggressive for EDM.

Story Mode is FlyU.ai's narrative video feature where AI acts as your screenwriter and director. Unlike regular generation that produces beat-synced visuals, Story Mode:

• Analyzes your song's lyrics and mood to write a coherent narrative script with scenes, characters, and camera directions.
• Designs a shot-by-shot storyboard - the AI plans close-ups, wide shots, action cuts, and transitions before generating a single frame.
• Maintains character and setting consistency across all scenes using Seedance 2.0's multi-shot coherence technology (Pro Mode).

Story Mode is available in both Lite (10-15 second previews) and Pro (10 seconds to 4 minutes, cinema-grade). It is perfect for artists who want a story-driven music video with a beginning, middle, and end - not just abstract visuals.

Concert Mode (Pro Mode feature) creates a full virtual stage performance video. The AI designs:

• A lead vocalist with phoneme-level lip-sync accuracy
• Band members - drummer, guitarist, bassist, and more
• A virtual stage with dynamic lighting, fog effects, and crowd atmosphere
• Cinematic camera movement - pans, zooms, and cuts like a real concert film

Concert Mode is powered by the Kling digital human model and is ideal for artists who want concert-style visuals without the cost and logistics of filming a real show. It is also popular for virtual performances, festival submissions, and social media content.

Yes. FlyU.ai's lip-sync feature, powered by the Kling digital human model, lets you:

• Upload a photo of any face - yours, an artist's, or a character reference.
• AI generates a performing character that sings your song with phoneme-level mouth movement accuracy - meaning the lips match every syllable, not just volume peaks.
• The character shows natural facial expressions that change with the music's emotion.
• Available in 7 languages: English, Chinese (Mandarin & Cantonese), Japanese, Korean, German, and French.

This is not deepfake or face-swapping - FlyU generates original AI visuals. The character is created from scratch based on your photo reference, performing within a fully AI-generated music video. Available in Pro Mode.

FlyU.ai offers three subscription plans (monthly or annual billing, with 60% off standard pricing):

All plans include unlimited AI image generation, unlimited AI music generation, unlimited video duration, lossless downloads, and priority support. One-time credit packs (1,500-20,000 credits, never expire) are also available.

Credits are FlyU.ai's generation currency. Each video generation consumes credits based on:

• Mode - Lite Mode uses fewer credits than Pro Mode.
• Duration - Longer videos consume more credits.
• Resolution - 1080p Full HD uses more credits than standard quality.

A typical Lite Mode 15-second generation uses approximately 50-80 credits. A Pro Mode 1-minute 1080p video uses approximately 200-400 credits. Exact consumption is shown before you generate.

Yes, you have full control.

• Upgrade - New credit allowance takes effect immediately. You only pay the prorated difference for the current billing period.
• Downgrade - Changes apply at the next billing cycle. You keep your current plan's benefits until then.
• Cancel - Your subscription remains active until the end of the current paid period. You will not lose access mid-cycle, and your generated videos remain downloadable.

All plan changes are managed from your Account Settings - no need to contact support.

FlyU.ai supports MP3, WAV, FLAC, AAC, and OGG audio formats. You can upload files up to 500MB in size. Alternatively, you can paste a link from YouTube, SoundCloud, or Spotify instead of uploading a file. Tracks up to 10 minutes in length are supported. The AI automatically analyzes BPM, tempo changes, and song structure regardless of input format.

FlyU.ai supports optimized export for every major platform - all from a single generation:

• TikTok - 9:16 vertical, 1080x1920, optimized for sound-on viewing

• Instagram Reels - 9:16 vertical, 1080x1920, aesthetic-optimized

Each format is optimized for the specific platform's compression algorithm. You can export multiple formats from one generation without re-rendering.

• Lite Mode (Free & Paid) - Standard quality, suitable for social media and testing.
• Pro Mode (Paid Plans) - Up to 1080p Full HD (1920x1080) with cinema-grade output.

Yes. Videos created with FlyU.ai on paid plans are royalty-free and you retain full commercial rights. You can use them for:

• Monetized YouTube channels
• Spotify Canvas and music streaming promotion
• Social media advertising and campaigns
• Client work and agency projects
• Commercial releases and music video premieres

Important: You are responsible for ensuring you have the rights to the original audio file you upload. FlyU.ai provides the visual generation tool - music rights remain your responsibility.

You do. FlyU.ai does not claim any ownership over the content you generate. Every video you create is 100% yours - you own the output, can distribute it anywhere, and can monetize it without paying royalties or licensing fees to FlyU.ai. We do not use your uploaded audio or generated videos to train our AI models.

FlyU.ai generates original AI visuals - every frame is created from scratch by AI, so there are no stock footage licensing issues. However, you must have the rights to the audio you upload. This means:

• If it is your own original music - you are fully clear to use FlyU.ai commercially.
• If it is a song you have a license for (e.g., as a content creator with royalty-free music) - you are clear within the terms of that license.
• If it is copyrighted music you do not own - the generated video may be subject to copyright claims on platforms like YouTube. FlyU.ai provides the visual creation tool; audio rights are your responsibility.

FlyU.ai takes data privacy seriously:

• Your uploaded audio and generated videos are stored securely with encryption.
• Your content is private to your account - other users cannot see or access your videos unless you share them.
• We do not use your content to train AI models.
• You can delete your content from our servers at any time.

For complete details, please review our Privacy Policy and Terms of Service.

Here are proven tips from our most successful creators:

• Use Pro Mode for any content you plan to publish officially. The quality difference between Lite and Pro is significant.
• Upload the highest quality audio possible - 320kbps MP3 or lossless WAV/FLAC. AI generation quality improves with cleaner, higher-fidelity audio input.
• Match the model to your style - Seedance 2.0 for realistic scenes, HappyHorse for anime, Kling for concert/lip-sync. Do not just use the default.
• Adjust beat-sync intensity - Use Low for ambient/classical, Medium for pop/rock/hip-hop, High for EDM/drum-and-bass.
• For lip-sync videos - Upload a well-lit, front-facing portrait photo with a neutral expression and clear facial features.
• Generate multiple versions - Try 2-3 different style-model combinations and pick the best.

If your output is not meeting expectations, try these troubleshooting steps in order:

1. Switch from Lite to Pro Mode - This is the single biggest quality lever. Lite Mode prioritizes speed; Pro Mode prioritizes quality.
2. Try a different AI model - Each model renders differently. If Seedance 2.0 looks too realistic for your anime concept, switch to HappyHorse. If Kling feels too cinematic, try Veo 3.
3. Check your audio source quality - Low-bitrate MP3s produce worse visual output because the beat-sync engine has less clean data to work with.
4. Adjust sync intensity - Too high on a slow ballad creates jarring cuts; too low on an EDM track looks disconnected.
5. For lip-sync specifically - Is the photo well-lit? Is the face clearly visible and front-facing? Are there multiple people in the photo? A clean, single-person portrait works best.

FlyU.ai is purpose-built for music video creation - not a repurposed general-purpose AI video tool. Here is how we differ:

• Beat-sync engine - FlyU.ai is the only platform with a proprietary audio analysis engine that syncs visuals to beats, tempo changes, and song structure. Runway, Pika, and CapCut have no native audio-to-video synchronization.
• 7 AI models in one platform - Competitors typically offer 1-3 models. FlyU.ai gives you seven, each optimized for different visual styles and use cases.
• Music-specific features - Lip-sync with phoneme accuracy, Concert Mode, Story Mode, lyric overlay engine, and Spotify Canvas export are unique to FlyU.ai.
• One-click multi-platform export - Generate once, export for TikTok, YouTube, Instagram, and Spotify Canvas simultaneously - no manual reformatting.

If you are creating general-purpose videos, Runway or Pika may be better fits. If you are creating content specifically for music, FlyU.ai is the specialized tool designed for that job.
