Screen recorded video Files don't open correctly
Hello, I have a serious problem with Hitfilm Express.
I have made a video on a game called Barotrauma, it was recorded and put into Hitfilm Express. I then edited the video and everything was fine. Cut some things added some things, then I exported it into "Youtube 1080p HD.mp4". The export seemed to be fine, but when I opened it all it showed was a Red Box with the words "Offline Media". I then went back to Hitfilm Express and saw that when loading the same file I saved, it wouldn't work and just say "Invalid Media" even though it was a MP4 file. I'm not sure if it is corrupted or not, but the video took me 2 hours to make and I don't want to start all over.
Any help would be great
