So somebody ran a red light right out in front of me. The first thing I did when I got home was to pull up the footage from my dashcam, but lo and behold there was a video that ends right before the crash and a video that ends right after the crash. The files were corrupted. Just in case anyone else has to go through the same thing, heres what I did to recover the data:

First, I used recuva. This is a general file recovery software that works in many applications. I used it to scan the SD card for any recoverable or deleted files. I sorted the list by the file state and restored any that were not listed as "unrecoverable" (so any files that were "very poor" or better). The files recovered from that would not play with windows video player. So next, I used this online tool I found. I did not trust it at first becuase it only shows you a 12 second preview and forces you to make an account. I was really expecting it to ask for a credit card, but I made an account and it was actually free to download the videos. The only problem is it is quite slow and I had 33 files that were recovered from the SD card. To solve that, I used this software. You can download it for free, but they will add a huge watermark to the videos if you do not pay. But what I did was used it to decrypt all 33 files at once so I could then go one by one through each one until I found footage of the crash. Once I did, I just took the name from that one file and ran it through the free online one and bam. The videos are really kind of funny because the corruption makes it look like I keep teleporting through space and time as it links a bunch of random videos together. I hope this helps anyone else with the same issue.
