image-to-video is agent-read markdown (skill) from notque/vexjoy-agent: FFmpeg-based video creation from image and audio..

Indexed from public GitHub and served as immutable, content-addressed versions.

The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Image to Video Skill

Combine a static image with an audio file to produce an MP4 via FFmpeg. Supports resolution presets, audio visualization overlays, and batch processing. For image generation, use `image-gen`.

## Deep References

| Signal | Load | Why |
|---|---|---|
| FFmpeg filter graphs for visualization modes | `references/ffmpeg-filters.md` | Scale/pad, showwaves, showspectrum, overlay filters |

## Phase 1: VALIDATE

1. Check FFmpeg: `ffmpeg -version`. If missing, stop with install instructions.
2. Verify both input files exist with absolute paths and non-zero size. Supported: PNG/JPG/JPEG/GIF/WEBP/BMP (image), MP3/WAV/M4A/OGG/FLAC (audio).
3. Determine parameters from the user's request -- do not default to static when the user requested a visualization.

| Preset | Dimensions | Platform |
|--------|------------|----------|
| `1080p` | 1920x1080 | YouTube HD (default) |
| `720p` | 1280x720 | Standard HD |
| `square` | 1080x1080 | Instagram, social |
| `vertical` | 1080x1920 | Stories, Reels, TikTok |

Visualization modes (off unless requested): `waveform`, `spectrum`, `cqt`, `bars`.

**Gate**: FFmpeg installed, both files exist, parameters resolved.
