According to Samsung, the slow-mo video performance of the Galaxy S21 Ultra is due to its large sensor.


The different models for Samsung’s S21 are not all the same. If the price and physical size did not give you a clue, then imagine sheets. And a nest is built between a list of individually named standards and numbers, a curious tidbit that ran out when it was detected on launch day: while the lower-end Galaxy S21 and S21 + 960 fps Super Slow Motion Video (0.5s Bursts up to), more premium S21 Ultra, with its advanced cameras, – or at least, it basically does not.

If that sounds familiar, that’s because last year’s S20 / S20 Ultra had a similar arrangement.

It’s not super straightforward if you’re not familiar with how it all works, but hidden in a footnote in the video recording section of the spec sheet, Samsung illuminates the difference:

“On the Galaxy S21 5G and S21 + 5G, users can record about 0.5 seconds of video with approximately seconds of playback at 960 fps. On the Galaxy S21 Ultra 5G, users can capture 480 fps for about 1 second. Can record and digitally amplify video. Video at 960 fps with playback of approximately 32 seconds. “

Simply put, this means that smaller S21 models can record 960 fps natively, instead relying on digital interpolation to create frames between 480 fps. can do The record, as with the S21 Ultra. In some cases, the difference will probably not be noticeable, but when it comes to recording slow-motion video, it gives smaller models a leg up.

The distinction is curious. As noted by the Android Authority, the phone does not have a chipset-level difference, and the Snapdragon 888 is that these phones must support 960 fps capture at a hardware level shared (in the US).

After publication, Samsung told us that the reason for the S21 Ultra’s digitally incoming slow-mo video is the phone’s large image sensor, which operates at low shutter speeds while recording video. Instead of artificially limiting smaller phones that can reach a higher shutter speed, Samsung chose to give them full 960fps recording capability and use its frame rate conversion technology on larger phones, noting that The difference between the two was not very understandable. .

I know this sounds like a strange interpretation, but so far we can tell, it is valid. This DP review article explains how the performance of electronic shutter (as you would with smartphone video) expands on the difference between shutter types, affecting not only pixel count, but pixel / sensor size and the S21 Ultra is. Does There is a larger primary sensor with a much higher pixel count than the smaller S21 and S21 +.

If you plan to use the feature, it may be a good idea to keep this difference in mind when selecting a model. Although the “digitally enhanced” 960 fps is probably sufficient, slo-mo aficindos may be better served by improved models.

Samsung has provided us with more information about the slow-motion video on the S21 Ultra, and confirmed that the larger sensor is responsible for the performance difference in larger phones. Our coverage has been updated with these details.
