The videos "not recorded" are no longer valid
Google has introduced a small change in its storage policy, like the children in Android Police. As you can see, go to the next Help section "Download or Unsupported Videos", now a clarification which reads as follows:
important: Videos uploaded after December 6, 2018 capture storage.
It is obvious that notice is new and tells us that there is Certain video formats that no longer benefit from unlimited storage of the business eats you for as much space in the plan you have associated with your account. This message is only shown in this section of the Google Photos Help Center, so it is understood that it only concerns, as we have specified, unsupported formats. And what are they? Well files counted with one hand, fortunately.
And that's if we consult this second section of the Google Photos Help Center, you confirm it list of accepted video formats are the most popular and used by users. They are following (17 formats in total): .mpg, .mod, .mmv, .tod, .wmv, .asf, .avi, .divx, .mov, .m4v, .3gp, .3g2, .mp4, .m2t, .m2ts, .mts and .mkv.
As stated in our source, you're unlikely to save a formatted video in Google's unlimited cloud.vob (a type of DVD-Video file), to name an example or a video in.raw, more like a professional camera. Still, this situation can happen, so the only thing you should know now is that since December 6th, Google Photos will no longer allow you to save them without occupying the corresponding space in your account.
Despite specific cases, so many of us use Google Photos and their unlimited storage worldwide that there have been "too many" cases of people who held files that could not be managed by the platform for free and they had to set the limit somewhere. While it's so … we will not protest, Google.
