I know that my question or request may be odd. My friend's car stolen and he is using it for his living :(. Fortunately we got a video from a cam that showing the crime and the thieves, the video shows another car used by the thieves, some of them ride my friend's car and others ride another red car, however, the video resolution is very low and I cannot even got the red car license number. Can any one here who know how to fine tune photos and video resolution help me. I am very sorry for my question and sending my apology to the admin(s) I knew that forum is not used for such question(s) but indeed I need help

What I have tried:

I just used movie maker to extract a photo for the red car. I tried many online image tuner and the result was not as expected

Despite what you see on the TV and in movies - especially NCIS and CSI - you cannot "enhance" low resolution video to get high resolution video and "read a number plate". That requires inventing information that doesn't exist: a low resolution image that has (say) 10 x 10 pixels per square inch contains 100 pieces of information, each of which is a single RGB or HLS value which describes that pixel, and no other. To convert this to a high resolution image that has 100 x 100 you would have to copy the value of one pixel in the original to 100 pixels in the "new" image (i.e. a 10 x 10 square) and that doesn't add any information - certainly not anything you could "refine" to produce anything that the police would accept as "the red car number plate" because you would have to use far, far too many guesses and could probably get any number you wanted!

That's why in the real world security camera footage of the bad guys is generally so poor that you can only really make out if they are male or female - enhancing low res images to produce sharp high res ones doesn't work as information isn't "compressed" into the low res image, it just doesn't exist.
