Police released footage of the SOB that killed my friend last Tuesday July 6/10. It's off a MP4 video server. Can any of you guys clean this up or blow it up to get a better look at his face?

Won't play for me. Sorry about your friend.
Not sure about Canadian law enforcement but in the states the FBI has mega video clean-up capability.

That video, anyway, is so horribly compressed that the guy's face never consists of more than 8 or 9 macroblocks...  Uncompressed original might have some more data but it's still pretty low res. It's kind of surprising that security camera tech hasn't caught up... a $150 cheapo-HD camera + a $1500 PC with several TB of drives would do vastly better. And my guess is it would cost far less, too... I suspect that the ******* selling security cameras rip people off because they're so well entrenched and have no reason to improve...

My neighbor was a CSI for our city and I spent many hours talking to him about the different video technologies and how they compare when used in police forensics. He said in almost all of the cases he's worked on tape has proven to be more effective than most of the digital out there. like perisoft mentioned. The resolution is usually so poor that they can't enhance anything, the data simply isn't there to begin with. The tools they use for analyzing tape is amazing though. Sorry again about your friend. I hope they catch the SOB and put him to justice.

There are HD surveillance systems... They're just not priced where a typical small business can afford them.
Take a modest $3-4000 8-16 camera IP-based PoE video surveillance system like a small business like the car wash might use, make it all 720p and you're going to make that system at least half-again to double the price... Decent HD cameras aren't cheap (a Cisco HD IP camera is about a grand), and the storage requirements alone would get expensive... 3 times 480p and 12 times QVGA if you want the same recording time... And it's going to be bigger, noisier, more complex, more failure-prone, and increase warranty claims and support requirements.
I think you're underestimating the engineering, hardware, software, and storage required to capture, compress and store 8-16 channels of 720p simultaneously in real-time 24/7, for years on end, and do it reliably and cost-effectively.

I don't see the need for a better video rendering in this case.
The fool in the video confirms what a prosecuter said in a crime show that I watch from time to time; "most criminals do really stupid things that eventually leads to their arrest"
Now, if that crime would have happened in my area, the police would have had that video running on all the media channels. The face is really not that important because and as mentioned, the security systems video quality suck.
So what happens when the video is played over and over in this case would be that someone would eventually recognize that personl in the video from the way he walks and the clothes he's wearing.
His walk is very distinct.
And I'm sure the guy did not buy those clothes to commit that crime. A criminal that would be smart enough to buy a special outfit to commit crimes, i'm sure would not rob a car wash.
Do your Police offer rewards for info leading to the arrest of criminals?
'round here, the media would run that video days on end. The police would announce a Reward. And before the day is out, the police would have a suspect.
And especially in the case of the really stupid, dirt-bag scum low life criminals who commit these kind of crimes. Even their own kind would turn them in for being so stupid. and any amount of a reward would be all that's needed.
