video-compress-to-size

video-compress-to-size is a skill for Cursor from godot-fun/godot-framework. It costs 115 tokens per session (1,146 once invoked), scanned A, original, MIT.

A video compression tool that re-encodes one video so it stays at or below a file-size limit you provide. It uses FFmpeg and can use supported graphics hardware when available, with a CPU fallback.

In plain words
What is it for?
Use it to shrink an MP4, MKV, or MOV to a target size, including files that must fit under a limit such as 50 MB.
Why use it?
It helps when a video is too large to upload, send, or store under a specific size limit. The original file is kept unchanged.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

video-compress-to-size scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 skill-dependency-manager �?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

.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):

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

Example:

assets/video/intro.mp4
  �?assets/video/video-compress-to-size/intro.mp4

Force CPU (slow, more precise two-pass):

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

Size Syntax

Input Meaning
50 / 50MB / 50M 50 mebibytes (1024² bytes)
500KB / 500K 500 kibibytes
1GB / 1G 1 gibibyte
52428800B exact bytes

--max-size is required.

Audio AAC 128k Lowered automatically on tiny budgets
Preset medium Mapped (e.g. NVENC p4); override with --preset
Already under limit Skipped [skip] �?(already under limit)
Safety margin GPU ~90% / CPU ~92% Headroom for mux / VBR overshoot

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
