I have made a video but I had to crop the footage to size it correctly on the screen as it was filmed in portrait. I used the 16.9 ratio which worked well but I need to export in 1080x1920 widescreen size. When I export the video looks like a thumbnail on the screen but the text I used is full screen albeit you cannot see the outer edges of each sentence. any ideas on how to get the cropped video up to full screen size. I have tried exporting in different screen ratios but to no avail
