If your camera ran out of battery or your computer froze in the middle of a recording, you may be left with an unplayable file. Here's a long explanation and a short tutorial on how to repair certain video files using a free & open program called Untrunc. <br /> <br />Untrunc homepage: http://vcg.isti.cnr.it/~ponchio/untrunc.php <br /> <br />Untrunc GitHub page: https://github.com/ponchio/untrunc <br /> <br />My modified version of Untrunc: https://nerdonthestreet.com/downloads/untrunc.tar.gz <br /> <br />Untrunc was created by Federico Ponchio. Please consider donating to him through his website if this program helped you! Also, if anyone wants to submit the changes I made to the program's GitHub page, it would probably be appreciated. <br />--- <br />Support us on Patreon! https://patreon.com/nerdonthestreet <br />https://nerdonthestreet.com <br />http://facebook.com/jacobgkau <br />http://twitter.com/NOTS_Network <br />https://plus.google.com/+NerdOnTheStreet <br />E-Mail: jacob@nerdonthestreet.com
