Format guide
What is OGV?
OGV file format is Ogg video — often Theora (and related) video in an Ogg container, created by Xiph.Org (2000s). OGV was an early open HTML5 video option before MP4 consolidated the web. Convert legacy OGV to MP4 for today’s phones, editors, and platforms.

OGV compression & quality
OGV compression: lossy. Lossy encoding discards some information to shrink files — re-saving repeatedly can accumulate artifacts. Typical size profile: Varies widely by encode. Quality note: Older Theora encodes look dated; treat as an archive to remux/re-encode
Quality: Older Theora encodes look dated; treat as an archive to remux/re-encode
Typical size: Varies widely by encode
Transparency & animation
OGV does not support an alpha channel. Convert to PNG, WebP, AVIF, or SVG when you need transparent backgrounds.
OGV is a still-media or non-animated format in typical use. Use GIF, APNG, video, or animated WebP when you need motion.
OGV metadata
Container metadata plus stream tags; phone videos often include orientation, location, and creation time.
