This videoconverter is everything you need!
I used Handbrake before and which is excellent but this little converter has the possibility to make your own presets based on ffmpeg code, which is awesome! Of course if you are not into code you can use the in-app presets. Nice thing also build in is a youtube downloader also tweakable. So it's a very flexible converter which you can set to your own liking. Also important to say is that it's very stable and reliable. If you need instructions and help you can find short instruction videos and a help document.
The only thing is that the in-app presets do not have a preset for GPU encoding. But of course it can use GPU encoding, simply make your own preset (eg. -map 0 -vcodec hevc_nvenc -b:v 2600k -c:a aac -c:s copy = encoding into h265 on a bitrate of 2600kbs and audio converted to aac including all video- and audiostreams and subtitles) or pick an app-in preset and edit the "libx265" into "hvec_nvenc".
For the developer, thnx!! Please keep up the good work!

definitely check into those virus the author on windows. I use linux appimage
LosslessCut is good for selecting clips then remuxing them together. Vidcutter appimage won't start for idea why.

Videomass also can quickly concatenate by remuxing clips together without reencoding just like LosslessCut or re-encode if ya wish.

here's a preset I use for rencoding and just need to change output mp4 or mkv and the timecodes. And it'll output 01.mp4, 02.mp4, 03.mp4, etc.

ffmpeg -i in.mp4 \
-ss 10 -to 20 \
-c:v hevc -strict -2 -c:a libopus -b:a 64k 01 \
-ss 1:00 -to 1:10 \
-c:v hevc -strict -2 -c:a libopus -b:a 64k 02 \
-ss 2:30 -to 2:40 \
-c:v hevc -strict -2 -c:a libopus -b:a 64k 03 \
-ss 6:30 -to 6:40 \
-c:v hevc -strict -2 -c:a libopus -b:a 64k 04 \
-ss 12:30 -to 12:50 \
-c:v hevc -strict -2 -c:a libopus -b:a 64k 05 \

Or this preset for decoding them and rencoding them all at once
must input seconds not HH:MM:SS so 1*3600 +36*60 +45 = 1:36:45

ffmpeg -i in.mp4 \
-c:v hevc -crf 33 -strict -2 \
-c:a libopus -b:a 64k \
-vf "select='\

Has an excellent GUI for youtube-dl
