I have been editing a video for a very long time, and was nearing the end but now all I see is a black screen on my preview box, and it says media offline inside of the clips. I have been working on this too long to start over so please help me find a solution!
Well, the last project you saved doesn't think that. Use the pop-up dialog that appears when you re-open the project. Choose the bottom of the three options.
Search for the backup.veg file and try opening that, or search for your missing file in Windows and replace the project media. Sorry I don't know how to help you further.
