Practical quality
FLV: lossy (legacy Flash codecs / H.264 in later FLV). Lossy targets trade size for speed — preview when it matters.
Wide compatibility
OGV is commonly used for Legacy open-web video archives and FOSS video history.
OGV vs FLV
A quick side-by-side before you convert — deeper comparison lives on the full guide.
| Feature | OGV | FLV |
|---|---|---|
| Kind | video container | video container |
| Compression | lossy | lossy (legacy Flash codecs / H.264 in later FLV) |
| Lossy / lossless | Typically lossy | Typically lossy |
| Transparency | Not supported / N/A | Not supported / N/A |
| Best for | Legacy open-web video archives; FOSS video history | Recovering old Flash-era recordings; Archival course videos from the 2000s–2010s |
| Typical size | Varies widely by encode | Varies; many old FLVs are low-resolution lecture captures |
| Browser / web support | Limited compared with MP4/WebM today | Flash is gone — convert to MP4 for HTML5 |
| Compatibility | Legacy open-web video — VLC plays many files, but phones and social platforms expect MP4 today | Legacy only — modern browsers will not play FLV without conversion; VLC can open many archives before you remux to MP4 |

Tip
Converting from OGV cannot restore detail already removed by lossy compression.
Does OGV to FLV reduce quality?
FLV is typically lossy (lossy (legacy Flash codecs / H.264 in later FLV)). Use a higher bitrate when fidelity matters, and keep the OGV master for archival.
FLV format guide →Should I keep the original OGV?
Yes when you may need to re-encode later. OGV: 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.

Frequently Asked Questions
More on quality loss: conversion quality guides · problem-solution guides
Does converting OGV to FLV reduce quality?
It can — both sides are typically lossy. A careful encode may look similar; repeated re-encodes cause generational loss. Prefer converting once from the best master you have.
Can you recover quality after converting?
Not from a lossy output alone. Return to the original master (or a better source). Converting to a lossless format does not resurrect discarded detail.
What is generational loss?
Damage that stacks when you decode and lossy-encode the same file over and over (for example JPG→edit→JPG). Edit from masters and export delivery formats once.
Where can I learn more about conversion quality?
Browse Format Convertly’s Quality guides for topics like whether conversion reduces quality, JPG↔PNG myths, WebP/MP3/MP4 tradeoffs, recovery limits, and generational loss — each links to the right converter.
What is a OGV file?
OGV is Ogg video — often Theora (and related) video in an Ogg container. 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.
Is OGV lossy or lossless?
OGV is typically lossy (lossy). That keeps files small but means discarded detail cannot be restored later.
What is a FLV file?
FLV is Flash Video — a legacy streaming format from the Adobe Flash era. FLV powered early YouTube-style streaming inside Flash Player. Flash is gone — convert FLV to MP4 to keep old recordings playable on modern devices.
