Do I have any chance of recovering my video?
The likelihood of repairing a corrupted video depends greatly on the source and extent of the damage. If the file is poorly saved but contains most of the data, the chances of success are high..

In general:
- Partially corrupted files: High probability of repair using free tools or format conversion.
- Files with broken headers but data present: Medium probability, using advanced programs or providing reference videos to the repair software.
- Videos overwritten or severely affected by malware: Conventional repair is almost impossible (forensic techniques are required).
Many programs we will see below can work miracles. If you don't have a backup, it's worth a try before throwing in the towel..
