i have a corrupt avi file that says its empty but im sure its not. I was recording with my hubsan and it crashed into water, stopping record?

i crashlanded my hubsan x4 with video into my neighbors pool while recording. i had to wait a week to get it out, and after waiting that long it works fine! the only problem is the reciever, the camera, and the footage i tried to get. when i crashed into the pool my quadcopter immediatly turned off. when i look at the avi video file it says that it is empty. this cant be true as i was recording! i saw the purple light as when i was recording before too! THE FILE WAS EVEN THERE! if its corrupted please help me uncorrupt it! thanks in advance, noble

Now it's empty because it never successfully finished writing the file when it crashed into water. It will not be readable, so it's corrupt.
