NVIDIA Demo - Beginning Of The End For Video Evidence In Court?

In a whitepaper, researchers describe "image to image translation", using deep learning techniques to convert sample images into alternate versions of those images, for example adding or removing seasonal elements to a scene, or shifting a scene between day and night.

Any video exported in standard formats could conceivably be run through a program to alter key details. Or, attackers could use exploits against recorders and alter video within the recorder itself to make recorded events or scene details appear materially different.

Image examples, showing changing hair color, expressions, etc. for an input image of a person:

An input picture of a dog in some pose, and then mutating the image to be a different breed dog in the same pose, with surrounding elements (grass, etc) intact:

Video examples (video are just a series of images to this approach):

This should add some interesting new arguments in the future to "admissible video evidence".

During processing, is there quantifiable evidence that the 'image to image translation' has been applied to native recorded video?

If so, I don't understand the concern regarding video evidence in court.

.avi files (historically, probably the most often exported format since it can be played in any Windows Media Player) have always had the vulnerability of being able to change items within the .avi shell.... ridiculous example: making Bugs Bunny run through the video clip if that's what you wanted.

I have personally provided hundreds of .avi clips as evidence to law enforcement that were used to convict wrongdoers. The only time that validity of evidence ever crops up is in high-profile cases that blow up because of the notoriety of the accused or the victim.

in a nutshell: this new video 'altering' capability should be an issue in .0000000001% of real criminal prosecutions where video evidence is critical to convicting the alleged perp.
