been working on a video for a very long time. just added the finishing touches and saved it and closed the editor. 3 hours later it doesnt open anymore and says file format not recognized and cant be opened.
i did notice that the file went to being 1.2 gb from 13,000 kb quite suddenly. although i did copy and paste one larger clip 5 times. i already had that clip several times in the video and i dont see how that could make such a difference.
the last thing i did was export a mp4 of the project (it said successfully) before i closed it. i also cant find that exported mp4 anywhere.
all other project versions are in the 10000 kb range and open without a problem. my last version before this will throw me back a month.
help!!!
