# Video Resize

> Change output width/height (-1 keeps aspect). Frame rate unchanged. **PyAV** resample → `COMFYTV_VIDEO`. This is a **PyAV media-processing** stage—not AI video generation via **Video Stage**.

## What this node does

**Video Resize** scales the full clip to **width × height**. Set **width** or **height** to **-1** to derive from the other dimension and source aspect ratio (ffmpeg-style). Use it to normalize resolution or shrink file size. It does not run text/image-to-video workflows.

**PyAV** backend; no GPU.

## When to use it

* Scale generations to 720p / 1080p for delivery
* Standardize size after Crop
* Smaller files before Demux / separation (Demucs pending)

## How it works

* **Stage** + **▶ Run**; upstream snapshot.
* **PyAV** `resize_video`; fps preserved.
* At least one dimension must be positive; both -1 is invalid.

## Types

| Type            | Notes        |
| --------------- | ------------ |
| `COMFYTV_VIDEO` | URL snapshot |

[bridges.md](https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md)

## Parameters

### video

Source `COMFYTV_VIDEO`.

### width / height

Target pixels, default 1280×720. Either may be **-1**.

## Outputs

| Output    | Type            | Downstream      |
| --------- | --------------- | --------------- |
| **video** | `COMFYTV_VIDEO` | Any video stage |

## Step by step

1. Wire upstream **video**, Run upstream.
2. Set **width/height** (e.g. 1280, 720).
3. **▶ Run**.
4. If both dimensions are fixed and ratio differs from source, image stretches — use -1 on one axis to preserve aspect.

## FAQ

**Q: Stretched picture?**\
A: Fixed width+height with wrong ratio stretches; try **width=1280, height=-1**.

**Q: vs Video Upscale?**\
A: Resize is geometric; Upscale (⏳ pending) is AI per-frame enlargement.

**Q: mesh2motion first?**\
A: **→ ComfyTV Video**, then Resize.
