FLV
FLV (Flash Video) is a video container that was used by Adobe Flash Player for web video. It typically holds H.264, VP6, or Sorenson Spark video with AAC or MP3 audio. Browsers no longer support Flash, so FLV files are usually converted to MP4.
OGG
OGG is an open, royalty-free container developed by the Xiph.Org Foundation. It usually holds Vorbis or Opus audio and is used by games, open-source software, and some streaming services. Some devices, especially older Apple products, do not play OGG, so it is often converted to MP3.
What happens when FLV becomes OGG
Source format
FLV is a legacy web video container with limited support in modern browsers and devices.
Target format
OGG is a container commonly used with Vorbis or Opus audio.
What changes
The audio stream is decoded from the FLV container and encoded as OGG audio.
The video track, frames, subtitles, chapters, and visual metadata are not included in the audio output.
- What is preserved
- Audio duration and channel layout are preserved when the source stream and target codec support them.
- What may be lost
- All visual content is intentionally discarded.
- Codec and quality implications
- Inspect the output before replacing the source, especially when the formats use different layout, codec, or editing models.
- Realistic limitations
- A FLV file with no decodable audio stream cannot produce OGG audio. Corrupt, encrypted, or unsupported codecs can also fail.
Conversion steps
- Upload a FLV file no larger than 1 GB.
- Confirm that OGG is selected as the target.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the OGG file and check the result before deleting your source.
Troubleshooting
- The FLV file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The OGG file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- The result has no sound or will not play.
- Try a broadly supported target codec and verify that the source contains a decodable audio stream.
Privacy and file retention
