Hi there,
I started using Kdenlive 2 years ago and I'm using it from time to time. I can see progress in stability - only one crash during work on this clip :) I had to use ffmpeg to create small version of MTS files, work with small video files and then replace them with originals in text editor (for some reason proxy clips don't work on my laptop).

Definitely flights are to expensive :( But... I'm going to go there again :)
