Please someone help. Using MacBook pro 2012 with Lightroom classic. 2 months ago i exported a video successfully with a song attached, images in portrait and landscape mode, and video clips. Now i cannot get that same slideshow with a few edits to export as video. PDF works fine but not useful. Have tried all solutions i could find and none have worked (open/close lightroom try again, use only 1 orientation of images, save show to same folder as images, etc). I also created a new collection with the original images and created several new test slideshows and again, MANY attempts and hours later attempting to export the slideshow and it stops the export after about 5 secs at the same point every time. Has someone got anymore ideas?
