Note: the “good” video should be recorded with the same settings (i.e. This has worked for me several times but there are detailed description in the repository so check that out if you need more info. It works by analyzing a video that was recorded by the same recorder/encoder (“good.mp4” in the example) then tries to recreate a moov atom for the broken video (“broken.mp4” in the example) based on that.Īll you need to do is download the code, compile it, then run. There is a tool called untrunc, but I recommend the fork by anthwlock as it has several improvements over the original (better performance, easier build and better compatibility). This can affect GoPro videos, iPhone recordings, live stream recordings, etc. Unfortunately the moov atom is unique to every video, even the recorders/encoders have different parameters. If the recording device loses power, crashes, runs out of disk space, or a download fails for any reason, the file gets broken. The moov atom is basically and index and technical description to the mp4 file, as it contains info about the whole video it can only be written once the video is complete, so it is usually located at the end of the file.
