I spent hours editing a video I filmed, I then restarted my computer because it needed an update. I tried to open the file and It has the clip, but in the timeline of the video it has a yellow triangle and an '!' in the middle. It says to double click to fix, then I tried to 'find' it, and it wasn't anywhere to be found. Is there anything I can do to get the video back? I will try to screen shot what it looks like. Any help is needed at this point, thank you so much for reading.
