Sonix transcribes FLV (Flash Video) files from the era when Flash powered web video. If you have legacy web content, archived videos, or downloaded Flash media, upload your FLV files and get professional transcripts.
Legacy Flash video format for web streaming
FLV files are also known as Flash Video Files. Most FLV files use Adobe Flash Player or Adobe Air to transmit audio/video over the Internet. Most embedded videos on the Internet are FLV files, but with the introduction of HTML5 videos, many streaming services have dropped usage of FLV files. You can sometimes see FLV files with a F4V file extension. FLV files aren’t as common now, but we still support them at Sonix.

Yes! Sonix still supports FLV transcription for legacy content. Whether you have old YouTube downloads, archived web videos, or historical Flash content, we extract the audio (typically MP3 or AAC) and deliver accurate transcripts.
FLV files are common in video archives from 2005-2015, downloaded web content, and legacy media libraries. If you've preserved videos from the Flash era, Sonix can help you create searchable text transcripts.
FLV audio quality varies significantly - early web videos used low bitrates (64-128kbps MP3), while later content often included higher quality audio. Clear speech typically transcribes well regardless of the compression level.
Sonix accepts FLV files directly - no conversion needed. However, if you want to preserve your videos for the future, converting to MP4 is recommended since Flash is no longer supported. You can transcribe either the original FLV or the converted MP4.
Absolutely! Legacy YouTube downloads saved as FLV transcribe well with Sonix. This includes content that may no longer be available online - your FLV archives can be converted to searchable, accessible text.
FLV files typically contain MP3, AAC, or Speex audio. All these codecs work well with Sonix transcription. The exact audio quality depends on the original encoding settings, which varied across different platforms and years.
