There's a difference. If someone manually claims a video through YT's content-ID system, they have to provide timestamps (this is enforced by Google).

If someone just sends a regular DMCA notice, they're only required (by law) to provide the URL, and Google has no choice but to take down everything at that URL, until/unless they receive a counter-claim from the poster.

The content-ID stuff is a convenience outside the law, if content owners (who have access to it) choose to use it. Anyone can file a DMCA notice, and Google has to respond in a particular way in order to be compliant with the law, and cannot impose extra requirements (like timestamps) before acting on the DMCA claim.

The law also requires that the DMCA notice describes what copyright is being infringed on. [1]

You can’t just go “this video infringes on my copyright, but I’m not going to tell you which copyright”. That isn’t a valid DMCA notice at all.

To quibble a bit, the video shows that YouTube's control panel tells users that a claim was "manual" and doesn't detail what "manual" means, or provide the DMCA notice (which is a written document, fwiw) that was filed, if one was.

I barely trust the information in the logging functions that I write, and those don't have legal consequences attached to providing extra detail.
