What Is FFmpeg Batch AV Converter?

Updated

FFmpeg Batch AV Converter is a free Windows GUI front-end for FFmpeg that lets you run FFmpeg's command-line encoding on many files at once without typing commands. It is aimed at both beginners and experienced FFmpeg users: you get drag-and-drop input, progress information, and a wizard, but you can still supply any custom parameter set. It runs on Windows 7/8/10 (32- or 64-bit) and requires .NET runtime libraries 4.6.1 or higher plus the Visual C++ 2010 redistributable. Linux users can run the older v3.1.2 build through Wine.

What it does

The core idea is batch throughput. Instead of encoding one file at a time, the app launches as many simultaneous FFmpeg processes as your CPU thread count allows, which the project describes as maximizing system resource usage. You can set encoding priority, pause and resume jobs, and trigger an automatic shutdown or a post-encoding script when the queue finishes.

Supported work, per the project page:

Area Capabilities
Video encoding h264, h265, NVENC, QuickSync, ProRes, AV1, Theora
Audio encoding MP3, AAC, AC3, FLAC, WAV, Opus
Batch processing Thousands of files, drag and drop, encoding priority
Streams Stream mapping and multiplexing, subtitle tracks or hardcoded subtitles
Editing Trim, concatenate, filter files
Capture/download Screen recording, M3u8 URL capture, batch YouTube download
Extras Image thumbnail extraction, multimedia file info, saved custom parameter presets

Who it fits

  • You have a folder of files to convert. Point the app at them, pick a preset or your own parameters, and let the multi-process queue run.
  • You already know FFmpeg flags. You can paste any parameter set, test it before starting, and save it as a favorite for reuse.
  • You want to avoid the command line for routine tasks like remuxing, subtitle muxing, trimming, or concatenating.
  • You need Windows-native behavior such as relative or absolute output paths, automatic renaming, and overwrite control.

If you only ever convert a single file with a simple preset, a lighter GUI may be enough. The advantage here shows up with volume and with custom FFmpeg arguments.

Availability and cost

The page lists v3.2.9 (64-bit) as the current Windows release, in both Installer and Portable form, with MD5 checksums published for each. Older builds include v3.1.2 for Linux via Wine, v2.7.7 (x86) and its portable variant, and v2.3.1 for Linux via Wine. The software is described as free, and the site asks for optional donations via PayPal, Buy Me a Coffee, or Patreon for translation support — no paid tier or license is mentioned. The project reports over 500,000 downloads since 2018 and links to source code, support tickets, discussions, and release notes.
