image-to-video

# Image to Video Skill Combine a static image with an audio file to produce an MP4 video using FFmpeg. Supports resolution presets (1080p, 720p, square, vertical), optional audio visualization overlays (waveform, spectrum, cqt, bars), and batch processing of matched image+audio pairs. For image generation, use `image-gen` instead. ## Reference Loading Table | Signal | Load These Files | Why | |---|---|---| | building FFmpeg filter graphs for audio visualization; encoding settings | `ffmpeg-filters.md` | Loads detailed guidance from `ffmpeg-filters.md`. | ## Instructions ### Phase 1: VALIDATE Confirm all prerequisites before attempting video creation. **Step 1: Check FFmpeg installation** Always run this check first -- many systems lack FFmpeg or have minimal builds, and skipping it produces confusing subprocess errors instead of clear install guidance. ```bash ffmpeg -version ``` If FFmpeg is not installed, provide platform-specific install instructions and stop. **Step 2: Verify input files exist** Both the image and audio files must be confirmed present before processing. Use absolute paths for all arguments -- relative paths break silently when the script executes from a different working directory. ```bash ls -la /absolute/path/to/image.png /absolute/path/to/audio.mp3 ``` Confirm both files exist and have non-zero size. Supported formats: - **Images**: PNG, JPG, JPEG, GIF, WEBP, BMP - **Audio**: MP3, WAV, M4A, OGG, FLAC **Step 3: Determine parameters** Re-...
