Still to Video
Turn one still image + one audio track into an MP4 — locally rendered, no AI model, zero credits.
Overview
The Still to Video node is the non-AI bridge from a still image into the video pipeline. Wire an image and an audio track; the node renders an MP4 whose length is the audio’s length — there is no duration field anywhere on the node. An optional motion preset (zoom, pan, or Ken Burns) animates the still; with motion set to none the render is a fast static frame.
It runs on the platform’s local media engine (FFmpeg) — no provider, no GPU — and costs 0 credits.
Configuration
| Field | Type | Default | Description |
|---|---|---|---|
| Motion | Select | none | none, zoom-in, zoom-out, pan-left, pan-right, ken-burns |
| Intensity | Number (1–10) | 3 | How strong the motion is — subtle (1) to strong (10). Ignored when Motion is none |
| Resolution | Select | 1080p | 720p, 1080p, 4K (names the short edge; the long edge follows the aspect) |
| Aspect Ratio | Select | 16:9 | 16:9, 9:16, 1:1, 4:3 |
| FPS | Select | 30 | 24 or 30 |
| Fit | Select | cover | cover crops the still to fill the frame; contain letterboxes it with the pad color |
| Pad Color | Color | #000000 | Bar color when Fit is contain (disabled otherwise) |
Credits
0 credits — always. There is no provider cost behind this node; it renders locally. No formula, no per-second component, no resolution multiplier.
Inputs & Outputs
Inputs: Image (required) · Audio (required — sets the output length) Outputs: Video (MP4, H.264 + AAC)
Duration
The output duration equals the wired audio’s duration, resolved automatically when the render starts. A render fails with a clear error (rather than producing a silent or zero-length file) if the audio’s duration can’t be read.
Best Practices
- Feed a still at (or above) the output resolution — the node never upscales your image’s detail, it only frames it
coveris right for full-bleed footage; usecontain+ a pad color when the whole image must stay visible (posters, artwork, documents)- Ken Burns at intensity 2–4 reads as “documentary”; 7+ reads as deliberate motion graphics
- With motion on
contain, the still moves inside the letterbox — the bars stay static
Common Use Cases
- Narrated slides: a generated image + a voiceover → a ready video segment
- Podcast/music visualizers: cover art + the track → an uploadable MP4
- Photo moments inside a longer edit — feed the result into Combine Videos
- Turning any Generate Image output into video without spending video-model credits
Tips
- Chain: Generate Image → Still to Video → Combine Videos to intercut stills with AI footage
- The audio input accepts anything that produces audio — Text to Speech, Generate Music, an upload, or an extracted track
- 4K with motion is the slowest path; at
noneeven 4K renders quickly
