I had created a video using an ATEM software (https://www.blackmagicdesign.com/products/atemtelevisionstudio) for a client and once the video finished recording and saving it produced two copies of the file. One of the files were about 1 MB while the other shot to a good 4.26 GB. I had tried several freeware programs such as Yodot to repair it but didn't work. As well as changing the format to .mp4 and attempting to play it from VLC instead of Quicktime Player. The computer is a Mac Mini running the latest OS X (practically out of the box) and we are using Vaddio Clearview HD Camera to record.
