About IFME

IFME is a graphical multimedia encoder for Windows and Linux, released as open source under GPL-2.0. It encodes, remuxes and repackages video and audio. It can merge multiple streams into a single file, drop streams that are not wanted, and handle subtitles and font attachments. It can also pull subtitles from another video without extracting them first.

Each encoder is described by a JSON manifest in a Plugins folder. IFME reads these at startup, so an encoder can be updated or replaced without recompiling IFME. On Linux, the bundled Plugins folder contains Windows binaries, so users must build their own ffmpeg, x264, x265 and similar tools and point the manifests at them. IFME requires a CPU with AVX support and does not run on 32-bit systems.

Key features

  • Encoders defined by JSON manifests and loaded at startup
  • Video encoders including x264, x265, SVT-AV1 and vvenc for H.266/VVC
  • Hardware encoding through NVENC, Intel Quick Sync and AMD AMF
  • Subtitle burning or embedding, and extraction from another video
  • Remuxing and merging of multiple streams into a single file
  • Startup checks that skip wrong-architecture plugins and can test-run encoders
Best for: Users who want a graphical front end for several video encoders and remuxing tasks on Windows, and Linux users who are willing to build their own encoder binaries.
Good for
  • Open source under the GPL-2.0 license
  • Individual encoders can be updated or replaced without recompiling IFME
  • Interface is kept small so that system resources go to the encoder
Watch out for
  • Requires a CPU with AVX support and will not start without it
  • Bundled plugins on Linux are Windows binaries and must be replaced with self-built tools
  • 32-bit systems are no longer supported

IFME FAQ

Does IFME require a specific CPU feature?
Yes. IFME requires a CPU with AVX support and refuses to start without it. AVX2 is strongly recommended. Without AVX2, a warning appears at startup and some encoders are unavailable.
Can IFME's bundled encoders run on Linux as shipped?
No. The bundled Plugins folder contains Windows binaries. Linux users need to build their own ffmpeg, x264, x265 and similar tools and point the plugin manifests at them. IFME on Linux also requires the mono-complete runtime.
