Video Trimmer

Video Trimmer cuts out a fragment of a video given the start and end timestamps. The video is never re-encoded, so the process is very fast and does not reduce the video quality.

For trimming Video Trimmer uses the ffmpeg binary, thus the non-Flatpak version depends on the muxers and demuxers available in your system's ffmpeg. The Flatpak package uses the org.freedesktop.Platform.ffmpeg-full extension.

The video preview goes through GTK 4 which usually relies on GStreamer, and therefore your system's or Flatpak GNOME Platform's installed GStreamer plugins.

The optional re-encoding also uses ffmpeg and thus needs the respective decoders and encoders to work. For .mp4 output extension Video Trimmer sets the encoder to libvpx-vp9 for better Flatpak support, for other output extensions it leaves the decision ffmpeg.
