Powerful and fast transcription

Transcribing audio and video files is now easier and faster than ever with RiverScript!

Traditionally, AI-powered file transcription tools have been limited by the fact that most services are only available online and work only in a browser, forcing users to upload their entire files to the internet – including large video files. This requires a stable internet connection and often means spending hours just transferring a file.

What’s more, there’s simply nowhere to transcribe large files such as high-quality videos that are tens of gigabytes in size. Every service has its own limits, which rarely exceed 5 or even 1 gigabyte. Users have to find third-party software and compress their files or split them into parts.

As a result, AI transcription – a task designed to make your life easier and speed up your work – becomes an ordeal in itself.

That’s where RiverScript, created specifically to solve this problem, comes in!

We’ve created a great solution that allows users to quickly and easily transcribe audio and video files up to 8 hours long and 50 gigabytes in size.

It’s the fastest and most convenient way to transcribe files.

How does it work? Why is it better?

Of course, RiverScript supports file transcription on the website, as many users are accustomed to. This is often the easiest way to get to know RiverScript. However, the web app is still limited by the speed of your internet connection and the technical limitations of the web and browsers.

That’s why we created RiverScript Desktop client, which is on average 3–5 times faster and more convenient. The desktop app also has an exclusive Live Recording Transcription feature that lets you record audio from any app – such as a video conferencing app, podcast, or lecture – and then transcribe it into text.

But when it comes to audio and video files you already have and need to transcribe, RiverScript Desktop client truly stands out. It is head and shoulders above any browser-based solution, allowing you to transcribe hours-long WAV files or tens of gigabytes of high-quality video in just minutes.

How does it do this? We don’t send your actual large files to the AI model. Instead, the app processes them directly on your computer. For example, it extracts the audio track from a video, compresses it into a convenient, lightweight format, and sends that instead.

As a result, a 50-gigabyte video will be compressed into just 12–14 megabytes of lightweight audio and transcribed within a couple of minutes.

Our app does all this at lightning speed because it is written in Rust, the fastest programming language. It’s genuinely fast and convenient – more convenient than any browser-based solution.

What file formats can RiverScript transcribe?

Our platform works directly with the open-source FFmpeg library, so we support several hundred audio and video formats and codecs. We have personally tested the most popular transcription formats, so below you can find a list of audio and video formats that RiverScript is guaranteed to transcribe.

There are also hundreds of other formats and codecs that our app can decode and work with – you can find the full list in the FFmpeg documentation.

Formats and codecs that RiverScript is guaranteed to support for transcription

Video formats:

  • MP4, MKV, AVI, MOV, WMV, WebM, FLV, M4V, MPEG, 3GP, TS/MTS, VOB

Audio formats:

  • MP3, WAV, FLAC, AAC, OGG, WMA, M4A, Opus, AIFF, ALAC, APE, M4B, WavPack, AC3, AMR

Please note that if you use the web version of the app in a browser rather than the desktop client, your browser may sometimes prevent you from uploading a file in an uncommon format because it does not recognize it as a media file. The solution is simple – just transcribe it directly in the desktop app.

Try it once – you’ll see the difference

As you can see, there’s a reason we say on our website that RiverScript transcribes everything. It really is an incredibly powerful way to transcribe files and is definitely worth trying and using in your work.
