Using GoPro *.mp4 files dragged and dropped onto the timeline. Made a 15 minute movie from various clips and music. Save file as a *.MVP then tried to export as a *.MP4, *.AVI, *.MPEG. None have worked. Close down Magix, reopen, reload movie and it plays in the timeline. File shows it as only 624kb.
I have made many, many movies up to 45 minutes long with previous version of Magix Movie Edit Pro 2013, but this new one Magix edit pro premium is having issues. Help!
Using Windows 10 home with plenty of RAM and disk space and processor.
