Video To Ogv

Converts a single video file to OGV (Theora + Vorbis in Ogg container) using FFmpeg for Godot-ready playback assets. Exports FFV1+FLAC lossless MKV intermediate then encodes Theora q=10 OGV for maximum fidelity. Use when the user wants to convert video to OGV, transcode MP4/MKV/MOV/WebM to OGV, export a cutscene or UI video, or mentions Theora, libtheora, VideoStreamTheora, or Godot video import.

File contents

Video to OGV

Convert a supported video file to OGV (Theora video + Vorbis audio in an Ogg container) via FFmpeg.

Lossy sources always go through a lossless intermediate first, then OGV — to minimize generation loss.

Export FFV1 + FLAC lossless MKV to video-to-ogv/lossless/
Encode Theora q=10 + Vorbis q=10 OGV to video-to-ogv/

Only Theora encoding is lossy; the intermediate decode is bit-perfect.

Rules

When this skill applies, read and follow skill-dependency-manager — run scripts as documented, install missing tools into .dependency/.

Quick Start

Convert a single video file:

.dependency/python/python .ai/video-to-ogv/convert.py --video path/to/video.mp4

Example:

assets/video/intro.mp4
  → assets/video/video-to-ogv/lossless/intro.mkv   (FFV1+FLAC intermediate)
  → assets/video/video-to-ogv/intro.ogv            (final Godot asset)

Format Defaults

Setting	Default	Notes
Pipeline	Lossless → OGV	Skipped when source is already lossless
Intermediate	FFV1 + FLAC (`.mkv`)	Written to `video-to-ogv/lossless/`; large but bit-perfect decode
Final container	OGG (`.ogv`)	Godot `VideoStreamTheora` format
Final video	Theora q=10	Single-pass from lossless intermediate
Final audio	Vorbis q=10	Preserves source sample rate and channels
Resolution / frame rate	Preserve source	Never downscaled by default
Existing Theora+Vorbis OGV	Stream copy	Bit-perfect when no overrides

Disk Usage

Lossless intermediates are much larger than source MP4s (720p ≈ 50–200 MB per 10 s clip). They are kept in video-to-ogv/lossless/ for re-encoding. Delete manually when done, or pass --clean-lossless to remove after each successful OGV export.

Common Flags

--video · -o / --output · --lossless-dir · --clean-lossless · --standardize

Custom output path:

.dependency/python/python .ai/video-to-ogv/convert.py --video path/to/video.mp4 --output path/to/out.ogv

Never overwrite source files. Input must be a single video file (--video), not a directory. Supported inputs: .mp4, .mkv, .mov, .avi, .webm, .wmv, .flv, .m4v, .mpeg, .mpg, .ts, .mts, .m2ts, .3gp, .ogv.

Agent Notes

Use the bundled script, not hand-written ffmpeg -i … commands.
Always run with no extra quality flags — the script only supports the lossless MKV → OGV pipeline.
Do not downscale or change frame rate unless the user explicitly asks.
Do not resample audio or change channel layout unless the user explicitly asks — omit --standardize.
Already Theora+Vorbis OGV? Stream-copied by default (no generation loss).
Tell the user where video-to-ogv/ outputs are; they swap assets manually when ready.
Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry same command.
Need 48 kHz audio → pass --standardize.
