Hi, Ive been given some cctv material via a usb stick concerning theft from their premises.I have never edited or used video material and have no idea how to start.Need advice please.Looking to crop,edit and print some images as the owner of images can display them on their property but at the roadside as they havent had any joy off the police.I presume they can display images like this?. Any help would be happily appreciated. Phil
If good quality images why not just pause video and take a picture of computer screen with DSLR and use to print as required? you would need to use a shutter speed of around 15/30th second to allow for the scanning of the screen.
The files on the stick should play directly on a computer media player, or they may have an inbuilt player. Once you can play the file(s) on your machine you can freeze and capture a screenshot which goes straight into photoshop. Probably...
I may be wrong but taking a capture from CCTV and putting it on public display singling out a person may be a human rights breach. I seem to remember a news article years ago where a shop keeper did this and the police arrested him following a complaint from the man in the photo, the police statement was that the shopkeeper had breached his human rights. It may be worth researching this aspect.
Aside from that I'd also be weary about 'editing' as this has the potential to distort the image is a way that will change it as raw evidence (eg. a processing technique could massively alter face detail).
I agree with Red Checker on this. Plus if the offender is arrested at a later date using the altered evidence you created you will get a rough ride at court on cross examination plus there is every chance it will be ruled as inadmissible and if the job relies on this evidence it will be dismissed. Probably by CPS on advice stage before court.
Never presume anything about legal matters and I suggest you tread very warily if meddling in an area like this where you have no relevant training or qualification. If this backfires you could end up in more trouble than the alleged culprit. It is probably best to get the property owner to seek advice from their solicitor about this before you get too involved.
As Photogenia said, play the footage with any media player. Pause at the right moment, then capture a frame. If you use something like PowerDVD, it has a capture button, as do some keyboards. If not, just play the footage in windows media player (or whatever you have) and use Quick Screen Capture, which can be download free, from here...
Then grab the frame you want. You might find that version of Quick Screen Capture is a trial version. If so you may only get 20 or so, goes at it.
Save as a JPG, then open the image in Photoshop to adjust contrast, crop, etc. if you need to.
It's all pretty straightforward. But please feel free to mail me if you get stuck. Dave
Thanks for everyone for their comments even the legal ones,.thanks RedChecker.On the legal side.The owner of the property & owner of cctv footage reported incident to police,they checked DVLA for owner of van but was a works van and they(the police) didnt have enough evidence to find the driver,who incidentaly nearly ran over the premises owner when challenged...All i want to do is display the images so if someone feels aggrieved by having their images displayed can come and see me and pay for the stolen items..why does the system & human rights organisation back the perpetrator and not the victim..another forum i think... On the footage,was taken on owner hard drive then saved onto laptop to which I saved on usb and loaded onto my laptop,i only have php7 & cs3and zilch experience with video work...but will try suggestions...Picture quality is very poor which is why police couldnt indentify the driver.Sorry for delay in replying.... Phil
