It is a good tool, but for me it only trims from the keyframes. To trim precisely, it has to re-encode, which, unfortunately, does not work on my machine for some reason. So, I just stick to ffmpeg cli.
I suppose that makes sense given that information is encoded as a series of key frames interspersed by 'I-frames" that simply encode the delta to the previous key-frame when using most compressed video algorithms. So cutting in-between key-frames doesn’t really make sense since the I-frame would no longer have anything to reference it’s delta to.

cli.That’s due to the source codec using keyframes, you can only cut without re-encode on those specific points.

Except if it’s lossless so there’s no harm in reencoding to accurately clip files
You’re confusing cause and effect. It’s lossless because it cuts at keyframes and does not re-encode.
If it did what you’re suggesting it wouldn’t be lossless anymore.
Lossless codecs can be decoded and reencoded without effect
LosslessCut doesn’t only use lossless codecs. It losslessly cuts video files encoded in lossy codecs.
