We are a language project and have started filming and editing our first videos. We have some people in our team who have edited and published before.
We have had erratic export-problems too, and when I googled it today, I found lots of users with similar looking problems: You have a “mainstream” project, with say, video from a consumer Sony camera (something like 1920 x 1080, progressive, 30fps) and all looks good in the Shotcut project.
And on export (we tried many different settings, not random, but conservative YouTube recommendations etc.) the properties for the exported video shows bad settings like proportions 1080 x 1080 instead of the expected 1920 x 1080. So different players (like VLC) can either not handle it, or show massive black frames around some rather small content. (put properties says that the actual video is still 1920x1080, just shows badly on the players).
It feels to me like a bug in the export module. Or there is a hidden “feature” which is bothering many new users. Please help - or if you prefer, I open a new thread. I would not tag something nasty about an OpenSource tool which I am using for free.
