Recently I wanted to cut a video (just export few seconds of a long video).

When everything still was AVI it was easy for me and I used VirtualDub. There I could decide if I just do a keyframe cut without having to encode it again, or a frame cut with having to encode this.

Nowadays having MKV, MP4 etc. I tried Lossless Cut which just gave me a black video. Open Shots Video Editor which is too complicated for this task and where I struggle to maintain the aspect ratio of the original video. Handbrake is a bit better, but also offers too many options for that purpose.

So I ended up using Online Video Cutter. But I wonder that there isn't any open source that just works as easily as that.

With LosslessCut, I've had good success with doing keyframe cuts with h.264 footage in MKV containers. Frame cuts end up in broken outputs pretty much every time. There's also Avidemux, which might be worth a try. More than likely though, if you want frame-precision in your cuts, you'll have to re-encode, at which point you could use something as minimal as Handbrake or a full NLE editor like Kdenlive.
