I generated my first video in Blender today. I folowed Paul Caggeggis instructions in "Introduction to Video Editing in Blender Part 01" on youtube. I have the latest Blender on an OpenSuse 15. When I generate the videos and open them I get only a unrecognizable ( screenshot below) video ( mov and mp4) or black ( .dvd ) in VLC. The original MP4 videos I merged in this video are MP4 and can be shown in VLC ( they have PAL resolution ).
Does anyone have a solution to my beginners question
