All your video, on one screen.
Open a file, choose codec, quality, size and tracks. VideoSTAX makes the new video, on its own or in a queue with many others.
VideoSTAX compresses and converts video files in the spirit of StaxRip, on macOS, Windows and Linux. Under the hood it uses well-known tools like FFmpeg, MKVToolNix and VapourSynth, all included in the download, together with your graphics card's hardware encoders when available.
The video transcoding studio for macOS, Windows and Linux.

Source, destination, filters, resize, codec, audio and subtitles share a single workbench. You see what goes in and what comes out at a glance.
Hardware encoders are much faster than software ones. VideoSTAX shows them only when your computer has a compatible graphics card and driver.
Choose x264, x265, SVT-AV1 or libaom in software, or a hardware encoder. Constant quality or bitrate, with − and + buttons right on the Codec card.
Click the thumbnail to compare the original with the cropped and resized result, using a draggable divider. On any frame of the video.
Copy each audio track unchanged or convert it to AAC, AC-3, E-AC-3, FLAC, Opus or MP3. Subtitles can be copied, burned into the picture or ignored.
Line up your files, start the queue and get on with your day. When it is done, VideoSTAX can even shut down the computer.
FFmpeg, MKVToolNix, VapourSynth and the encoders are already in the download. The Apps window shows what was found and its status.
Pick the file for your system. Every download comes straight from the official releases on GitHub.
Extract the folder and run videostax_ui.exe, keeping the whole folder together.
Make the file executable with chmod +x and run it, on any distribution.
Install with sudo apt install ./VideoSTAX-v0.9.3-amd64.deb.
Install with sudo dnf install (on openSUSE, sudo zypper install).
macOS 27 or later on Apple Silicon (M1 or newer), Windows 10 or 11 64-bit, a recent 64-bit Linux (e.g. Ubuntu 22.04+, Fedora 38+). 8 GB RAM (16 GB recommended), 1280×800 display.
Free, distributed as ready-made builds through the videostax-releases repository. Includes third-party open source software (FFmpeg, MKVToolNix, VapourSynth and others), each under its own license.
Yes, you can download it for free from its GitHub releases page. If you find it useful, you can support its development with a donation.
No. FFmpeg, MKVToolNix, VapourSynth and the encoders are included in the download: there is nothing else to install.
A hardware encoder appears only when your graphics card and driver support it. Update the GPU driver and restart VideoSTAX: the Apps window shows which tools were found.
With x264 and x265, a CRF between 18 and 23 is a good start: lower means better quality and a bigger file. With hardware encoders, start from the value VideoSTAX proposes and change it in small steps.
Encode HDR at 10 bit by choosing it in the Codec card. VideoSTAX warns you in the Destination card when HDR would be encoded at 8 bit.
The first time, open System Settings → Privacy & Security and click Open Anyway next to VideoSTAX. On Windows, if SmartScreen shows a warning, click More info → Run anyway.
Closing stops the running jobs, but the queue is saved: reopen it with Jobs → Load and start it again.
VideoSTAX is developed and maintained independently. If it saves you time on your video work, a donation turns into new features and improvements.
