I was importing some video files from my phone into Avid. 100s of them worked except for 4. I got an error message that the format wasn't supported (despite being exactly the same as the rest of the files). I tried converting them to avi, they just came up with a green screen. I tried uploading them to Youtube and redownloading them again, and got the same errors. I assume they must be corrupt in some way, except that they play back fine in VLC. I tried putting them into other programs and had the same errors for all of those as well. At a loss of what else I can do to get these files working properly.
