Sobre los archivos Y4MComparativa de ventajas
OGV Ventajas
- Patent-free codec (Theora) and container (Ogg).
- Mandatory for Wikipedia uploads — preserves public-domain video.
- Good for small educational clips.
- Open-source reference implementations.
Y4M Ventajas
- Uncompressed raw YUV — codec benchmark truth.

Limitaciones
OGV Limitaciones
- Compression lags H.264 by ~40% at equal quality.
- Hardware decoders never adopted Theora.
- WebM (VP9/AV1) is the modern open-codec choice.
- iOS and Safari never supported Theora natively.
Y4M Limitaciones
- Enormous file sizes.
- Development-only — not for consumption.
- No metadata beyond basic stream params.

Preguntas frecuentes
OGV (OGV Video) is a video container format that bundles one or more video streams, audio tracks, and optional subtitles into a single file. The container format determines how metadata is organised and which codecs can live inside; the visual quality itself depends on the codec (H.264, H.265, VP9, AV1) rather than the OGV wrapper. It is part of the video files family.

VLC, MPV and PotPlayer play nearly every OGV file on desktop. Browser support varies: modern Chromium, Firefox and Safari play common containers via the HTML5 <video> tag, but niche OGV variants may fail. If a device refuses your OGV, convert to MP4 with our OGV to MP4 converter for universal playback.

If a device refuses your OGV, converter to MP4 com our OGV to MP4 converter para universal playback.
Upload your OGV to KaijuConverter and pick MP4, MOV, MKV, WebM, or any other target. Our pipeline uses FFmpeg under the hood and stream-copies when codecs are compatible (no quality loss) or transcodes at high-quality defaults otherwise. Conversion runs server-side; both files delete within two hours.
Only when the target requires re-encoding. If the codecs inside OGV match what the target container supports, FFmpeg stream-copies the streams and the output is bit-identical to the source. Transcoding uses transparent quality defaults (CRF 20–23 H.264) and produces output indistinguishable from the original at normal viewing distance.
