OnePlus only just launched the OnePlus 8 series, but the brand is not neglecting the older OnePlus 7 series. Last week, the OnePlus 7T family received its third OxygenOS Open Beta update. The update introduced a handy camera lens dirt detection feature. It also included the April 2020 security patches. But there was more.
Apparently, OnePlus also secretly enabled the 960fps slow motion video recording support on the regular OnePlus 7T. Noticeable, the company failed to mention this feature in the OTA changelog.
A Redditor with the screenname “sneakerspark” revealed this new feature when he noticed it on Open Beta 3. He revealed that the beta provided 720p@960fps slow motion option on the stock camera. That is not all. He also followed up with a reply, saying that the beta also brought 4K@30fps wide-angle video support.
Back in September 2019, OnePlus disclosed that they were working on these two features. However, it is surprising that the company did not mention them in the official changelog of the Open Beta 3. It is possible that OnePlus still has some work to do on the features before being confident enough to officially announce them.
It is of note that the OnePlus 7T’s camera sensors do not have enough power to actually record videos at 960fps. However, it can handle up to 720p@480fps. So to achieve the 960fps slow motion, OnePlus only needed to incorporate some kind of frame interpolation algorithm.The final result of this algorithm may not be as crisp as native 960fps slow motion, but that will not even matter to many users.
