VideoSTAX compresses and converts video files. Open a file, choose how the result should look (codec, quality, size, audio and subtitle tracks) and VideoSTAX produces the new file, alone or in a queue of many files. Everything happens on one screen, in the spirit of StaxRip.

It uses well-known tools under the hood (FFmpeg, MKVToolNix, VapourSynth) and the hardware encoders of your graphics card when available: NVIDIA NVENC, Intel Quick Sync, AMD VCE and VAAPI. All tools are included, so there is nothing else to install.

One-screen workbench

• Source: codec, resolution, frame rate, bit depth, HDR/SDR, duration, bitrate, audio and subtitle tracks at a glance
• Destination: output file, a summary of what changes, estimated size and warnings (for example HDR encoded at 8 bit)
• Filters, resize and codec side by side; audio and subtitles below

Files and queue

• Single files, many files, Blu-ray folders, merging several files into one, batch lists, drag and drop
• A job queue with order, start and a log for each job; time left and speed while encoding

Quality control

• Frame preview: compare the original and the result of crop and resize with a draggable divider
• x264, x265, SVT-AV1 and hardware encoders, with CRF, bitrate and advanced options with search
• Copy or convert each audio track, keep or burn subtitles

Private by design

• No account, no ads, no tracking: videos are converted entirely on your computer
• Free, in English, Italian, German, French and Spanish

VideoSTAX opens files in your home folder and on removable drives (/media, /run/media). The NVIDIA, Intel and AMD encoders are included in the amd64 snap only; on arm64 use VAAPI or the software encoders.
