What is it?

Frame is a desktop media converter that wraps FFmpeg in a native graphical interface. It exposes codec, bitrate, resolution, frame rate, pixel format and filter settings for video, audio and image files, so users can run conversions without writing command-line arguments.

The app is built with Rust and the GPUI-CE UI framework. Its conversion core handles FFmpeg argument generation, source probing with ffprobe, compatibility validation, task queueing with concurrency limits, and parsing of FFmpeg progress and log output for live display. Supported outputs include MP4, MKV, WebM, MOV, GIF, MP3, FLAC, WAV and several image formats, with hardware encoders available on macOS (VideoToolbox) and Windows (NVENC) builds.

Subtitle handling covers burning in .srt, .ass and .vtt files with styling options, as well as PGS, DVB and related workflows for MPEG-TS files. Prebuilt releases are distributed via GitHub, WinGet, Homebrew and Flathub.

Key features

  • 01Video, audio and image conversion with per-codec encoder, bitrate and preset controls.
  • 02Video processing options including scaling, crop, rotate, flip, FPS conversion and image overlay.
  • 03Audio normalization, limiter, compressor and noise reduction filters.
  • 04Subtitle burn-in for .srt, .ass and .vtt files with styling controls.
  • 05Metadata preservation, cleaning or replacement, plus MPEG-TS program info via ffprobe.
  • 06Concurrent task queue with live FFmpeg progress and logs.

Use cases

  • Converting screen recordings or camera clips to MP4 or WebM for sharing.
  • Batch-transcoding a folder of audio files to FLAC, MP3 or Opus.
  • Burning subtitles into videos for distribution without using a terminal.
  • Preparing broadcast or Blu-ray related MPEG-TS and subtitle streams.

Things to know

  • The app is not code-signed, so macOS and Windows may block it and need manual approval.
  • Hardware encoders are only bundled on macOS (VideoToolbox) and Windows (NVIDIA NVENC); Linux uses software encoders.
  • Licensed under GPL-3.0, so derivative distributions must also be GPL-licensed.
