Avigilon Native Export

[cglaeser 0]

When exporting Avigilon native, is the compressed video expanded to a series of images? Is it possible to export the compressed video in native format?

".ave " is your native format

rest are just standard file formats

One hour of sparse motion video seems to get extremely large. It also seems to take a while. So, I'm guessing it is expanding the H.264 video stream rather than simply copying. Is that your understanding?

I think when export as AVI

it's doing trans coding using relatively old Microsoft codec

with "ave" I would not know exactly

i have feeling it's being generated on fly

actually going to ask support just for fun

if they can share those details

So, Avigilon native uses AVI?

When you export in AVE there is no option to adjust the compression. You do have the ability to skip frames.

Absolutely Not

 

AVI just one of the option to export

have a look at my pix above

AVE is their own "native" proprietary file format

OK, thanks. I had assumed that native AVE was just a copy from the video database to a file with a wrapper added, but there is a fair amount of processing and the file can get very large for a modest about of video, so it's apparent it is not just a simple copy. Our local police department has an Avigilon player (they get AVE files from Safeway). I was going to give a native file to the DA for a recent DUI arrest, but the file is too large to bother. I'll just use .avi and a few select images.

You must export in .ave (native) to hold up in court.

I have provided video surveillance evidence in about fifteen criminal cases. Based on my experience, what the police, detectives, and DA want are high quality video and images. The bulk of what they receive in other cases is low quality video of "the two dudes" with little forensic value, and when I give them several 5MP images of the key frames that shows faces, vehicles, and license plates, they are thrilled. I provide the video and images in .avi and .jpg format in the cloud so they can easily review the evidence and share with other departments in neighboring cities. I don't know how many of these cases actually went to trial, but I do know that this information was used in warrants, arrests, and resulted in jail time. Although I do lock the surveillance video sequences on the timeline to protect it from overwrite so it could be reviewed at a later date, I have never provided a .ave file nor have I been asked to provide one. Given that the vast majority of homes and business with video surveillance equipment use cheap DVRs, I doubt a format like Avigilon's .ave is available in most criminal cases.

What I think Smith means is the AVE files can be authenticated where the AVI videos can not.

Correct,

And in a criminal case the defense will and can pick it apart if it's not in Native Format. They can easily claim the video has been doctored.

Native format eliminates that.

 

The defense will require you to document the manufacturer of the equipment, the chain of custody of the export, and the credentials of the person exporting it. Been there done that.

And in really serious cases

Crown will confiscate computer for few days or more

Yet another compelling reason why your NVR should not be the same as your personal computer.

Most cases result in a plea deal, where the defendant pleads to a reduced charge in exchange for a reduced sentence.

I think its very unlikely that anyone will request the video be authenticated unless this is some big case.

In shoplifting and prostitution cases I have been involved with the Defense required all the information I stated before trial in discovery.

And one "authenticated" they take it that video is authentic and unedited?
