Unfortunately, it happens to everyone at some point in time: Critical video evidence isn’t as sharp as you need it to be! Either the lighting was poor at that particular point in time, the camera was shaking due to wind, or excessive audio interference made a clip unusable.
In these instances, you might want to consider having an outside service spruce up your recording. One such vendor, Forensic Protection of Los Angeles, has an excellent reputation for video enhancement. Some interesting demonstration Before and After clips can be found at http://www.forensicprotection.com/services.html
And the price is quite reasonable: $100 will correct a single image (check out the license plate at http://www.forensicprotection.com/deblur.html), and $395 will correct a video clip of up to 20 minutes long.
There is even a service for authenticating audio or video evidence, in case your recordings ever have to stand up in court!
For more information, contact Forensic Protection at (818) 375-1700 or via their web site.
