Version 1.3 was released. Three bugs were fixed: 1} decoding 'vp9' with multi-threading wasn't working, setting the frame-type to 'slice' works and 2) encoding 'mpeg2' fails due invalid timebase and 3) memory leak when changing a program (see picture below).
New: hardware acceleration is supported.
Also some improvements were done. And at least: FFmpeg-7 is now supported.

CutterFF is a small program for UNIX (Linux, or Windows if compiled with MingW) for cutting videos using FFmpeg and GTK+. You can set cutpoints everywhere in the video and save it to disk, optional using a different format and a bitstream filter. You can select which streams should be written to the output file, so it is also possible to extract the audio only. If your video file contains several programs, you can choose the desired one.
Depending on your libraries you may also save the currently displayed picture as image (e.g. 'jpeg', 'gif', 'png') to disk, the width and the height may be choosen, grayscale is also possible if supported by the encoder.
Since FFmpeg is supporting a lot of formats and codecs, i am not shure if CutterFF will work with all of them. I have tested it with only some formats like 'avi', 'flv' 'mpeg2video', 'mpegts', 'mp4', 'matroska' and 'webm', and some codecs like 'mpeg2video', 'avc (h264)', 'hevc (h265)', 'mpeg4' and 'vp8'.
At least no decoding and encoding is done, the streams will be simply copied, which is done fast.
If soft cutting is enabled, then the frames at the cutpoints will be de- and encoded. The number of frames depends on the GOP-size and may vary. The additional time required for this depends on the number of cutpoints, the number of frames in a GOP and the video encoding ('mpeg2video' is faster than 'hevc'). All the other frames will be copied as mentioned above.

CutterFF is distributed under the terms of GPL2 or later.

• required: ANSI C Compiler (like GCC)
• required: at least GTK-2.18, GTK-3.10 or GTK-4.6 (or higher versions of them)
• required: at least FFmpeg 3.0, up to 7.0
• optional: libintl library from GNU gettext package (or libc with gettext support - for internationalization of the messages (for now only german is supported)
• optional: MingW (compile for Windows)
• optional: static libraries needed for GTK-2 (MingW only - seems not to be valid anymore)

Downloads

Two Linux programs (which are using the shared libraries from GTK+-3 and FFmpeg) can be downloaded for either 32-bit (136KB) or 64-bit (122KB).
Which hardware accelerators are supported depends on the configuration of the installed FFmpeg.

• Should work with actual distributions (FFmpeg-7.0, GTK-3.24.34, and other libraries requiered by GTK)

Two Linux programs (GTK+-3 like above, but with FFmpeg-7.0 statically linked, if your distro lacks some formats and codecs like the ones which I have used for testing, also the encoders 'libx264' and 'libx265') can be downloaded for either 32-bit (4.5MB) or 64-bit (4.7MB).
The supported hardware accelerators are 'vaapi' and 'vdpau', and the shared libraries 'libva', 'libva-drm' and 'libvdpau' must be installed.

• Should work with actual distributions (see above).

Two Linux programs (both 64-bit) running GTK+-4, one using the shared (126KB), and the other the static (4.7MB) FFmpeg libraries.

• Should work with actual distributions (GTK-4.6.0, FFmpeg like above).

• The GTK+ libraries are statically linked, the FFmpeg-7.0 libraries and the encoders 'libx264' and 'libx265' as 'dll', tested with Windows-7 (32-bit) and Windows-11 (64-bit).
