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.

I loved how accurate you are even in Dutch!
Blown away by what it does! Accuracy, ease of use, affordability, simple straightforward interface with well thought out additional tools and functions. Superb!
Content is still king. Google can’t crawl audio from webinars and videos. Getting that content transcribed with Sonix is an absolute must if you want to drive more leads to your web site.
The recording I transcribed was poor quality at best, so I was pleasantly surprised by how accurately Sonix captured the text. And your editor is absolutely brilliant!
I have a 30-40 minute commute to work and like to dictate memos and other brief documents along the way–but I haven't had an easy way to get them transcribed...until now. Thanks Sonix!
I loved that Sonix supports so many languages. I've been working on a project that involves speakers of 6 different languages and it allows me to translate everything into English ...
You saved me! I got everything done in three days and I was sure it will take me a month.
I'm a journalist and I'm finding that Sonix is a very valuable tool.
