[contingencies]

I was a paying Pro customer for Lightworks but when I had a very important and conceptually simple project come up - conversion of a large archive of globally unique, 8mm film reels that had been pre-digitized in to cut and labelled portions - the software couldn't cut the mustard and they literally came back to me with a reply like "that is not our use case".

The content was super important stuff - early footage of many areas of the world not otherwise filmed - and was destined for Wikimedia Commons.

It was the worst experience I've ever had with commercial software since Windows 'corrected' an NTFS volume in ~2005 and nixxed the lot. From memory it was something to do with the input codec (beyond my control as lossless was a requirement), the output codec, and the aspect ratio. The software just couldn't cut the stuff. I was left to go back to ffmpeg and VLC. I will never again waste time learning a commercial UI.
