Can’t believe it!
So many electrons going to and fro and so many different situations, cannot speak to yours. But I tried numerous AVI and multiple video conversion Apps and none could stomach the archive video files I had on a hard drive. REMO AVI repair, tossed its hands up in defeat. “Missing Video/Audio files, cannot repair.” SUPER converted 55 minutes of video in less than 10 minutes. So far, that’s all I’ve done but I now have hope of saving dozens of hours of archived material.
