I think I may be having a similar problem. My Pixel 1 recorded a vertical video instead of a horizontal video. I can preview the vertical video just fine in Shotcut v. 19.01.27 on Windows 10, but when I drag it to the timeline, the program crashes. If I try applying a filter to rotate the video -90 degrees and scale it 178% before dragging it, the program still crashes when I try to move the clip to my timeline.
I just wanted to make sure this was the same problem listed above that will be fixed in 19.02.
I’m loving the software, keep up the great work.
