How to transcode, "edit" and or cut clips out of HEVC videos?

[bonkabonk]

I've downloaded some videos with HEVC. Normally, for XVID or mp4 etc. I could use VirtualDub or AviDemux to cut out the parts I liked.

But these tools don't seem to work because the vids are encoded with HEVC.
Vdub won't even play the file, it gives me an error:
Unsupported ftyp major_brand: 'iso4'

I've used MKVtoolnix, and it does cut out clips out of the video ... sort off. It's doesn't work like VirtualDub or AviDemux where you can set a beginning and an end and then choose to which codec you wanna transcode it all into.

For example, if I wanna cut a clip out of a 2 hour video from 40m25 to 41m53s, how would I do that:
- with MKVToolnix?
- with VirtualDub?
- with Avidemux?

ffmpeg maybe

ffmpeg -i input.mp4 -ss 00:01:45.480 -to 00:01:46.606 (video,audio codec parameters here) part.mp4

VirtualDub + Avisynth + FFMS2. Example:

LoadCPlugin("B:\AVSplugins\FFMS2\c\ffms2.dll")
FFVideoSource("video.mkv", fpsnum=30000, fpsden=1001)
