METHOD 1: Increase the File Size

WINDOWS INSTRUCTIONS

Note: The latest version of the utility may have been patched to prevent using this trick, though as of December 2014 I have verified it will work with v1.9.0.1, as long as you triple the video size rather than double it. If that doesn't work for you, both the doubling method and the -save 100 method will work with v1.8.0.0, which you can download here: Code: https://mega.nz/#!CIxBAQoa!ctEJUEd9jfFmyByLmiGO4kv1aYMnEMaFK-OGb47vdTw you will have to run it with your computer disconnected from the internet, or else the program will show an error saying there is a new version available, close, and open the Grau website.

a. Make a copy of your corrupted video file and put it in the same directory as the original. Rename the two files something simple like "video1.mp4" and "video2.mp4."



b. Open the Windows command line (run>cmd) and navigate to the folder with the video files using the cd command.



c. Type "copy/b video1.mp4+video2.mp4" (without the quotes) and hit enter. It will now merge video2 into video1, so video1 will have doubled in file size.



d. If using version 1.9.0.1 or higher, run the command in step (c) a second time, which will triple the file size instead of doubling it (quadrupling may also work though I haven't tried that).This defeats the bugfix that patched the doubling exploit, since the file is no longer exactly twice the length of the original video. You will however have to manually edit out a portion at the end of the repaired file where the video will loop back and start over at the beginning.
