Compresses a single video file to stay under a user-specified max file size using FFmpeg. Prefers GPU encoders (NVENC / AMF / QSV) with VBR bitrate targeting; falls back to CPU two-pass H.264/HEVC. Use when the user wants to compress video, reduce video file size, shrink MP4/MKV/MOV under N MB, GPU encode, NVENC compress, or re-encode a clip to a size limit.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Video Compress To Size

Re-encode a supported video so the output is **at or under** a given max file size.

**Default:** probe and use a GPU encoder when available (NVIDIA NVENC → AMD AMF → Intel QSV), single-pass VBR. If no GPU works, fall back to **CPU two-pass** (`libx264` / `libx265`).

## Rules

When this skill applies, read and follow [dependency-manager](../dependency-manager.md) — run scripts as documented, install missing tools into `.dependency/`.

- Run `compress.py` through **`.dependency/python/python.exe`**. Never use host `python` / `ffmpeg`.
- **Never overwrite sources.** Outputs go under `video-compress-to-size/`.
- Use the bundled script — do not hand-write equivalent FFmpeg commands.
- **One file per run** — pass `--video` with a single file; repeat for each clip in a batch.

## Quick Start

```bash
.dependency/python/python .ai/video-compress-to-size/compress.py --video path/to/clip.mp4 --max-size 50MB
```

Bare numbers mean **MB** (`--max-size 50` ≡ `50MB`):

```bash
.dependency/python/python .ai/video-compress-to-size/compress.py --video assets/intro.mp4 --max-size 50
```

Example:

```
assets/video/intro.mp4

How to install

The exact contents, by fingerprint
mdr add godot-fun/godot-agent/video-compress-to-size@sha256:716bcbd0e73299d8

The line at the top of this page pins the label git:20261101.d8fbf4c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
