How to improve video quality, is it possible?

Question

Video processing

Hello.
I will not go into details, but we will have to consider the video from the yard surveillance camera. The quality of the video will probably be lame, I would like to improve it as much as possible. Is it possible? If possible, please tell me the possible ways, techniques, programs, options ...

Answer 1

No impossible. This only happens in CSI.

Answer 2

It was probably already explained above that this is only possible in Hollywood)
But of course you can always play around with filters like contrast and sharp ..
And one more thing, how was the video obtained? The fact is that all registrars usually write video to their disk with proprietary codecs in a format something like .h264 or .x264, and they send a completely different quality picture to the network for broadcasting. So, as an option, it’s better to get the original from the registrar’s disk (not over the network) and the proprietary CMS with drivers installed on the computer, and already explore the video in its player
