You can't play a video after a battery died during recording? Don't worry, it can be easily fixed with MP4Fix. It is designed strictly to repair camera recordings and it doesn’t support fixing or transcoding videos downloaded from the Internet. This app uses LGPL licensed JAAD decoder library.

How Is It Possible:

All you need is another valid video recorded on the same device using the same app. You can watch the repaired files for free! Saving or sharing them requires one time purchase of only $3.99.

Pleas note:

To utilize full functionality of this app you have to purchase via in-app purchase. We couldn't find the crack yet. It will be made available as soon as we get it. During this period if you come across the full version you can surely send us.
