Samsung Galaxy S21 Ultra 5G Review: Selfies, Video QualityBy cheatmaster 01:12 Sat, 07 Aug 2021 Comments
The Galaxy S21 Ultra borrows the selfie capturing camera from the S20 Ultra - a 40MP Quad-Bayer shooter with autofocus. It saves 10MP images, but you can opt for 40MP, too.
Samsung's bizarre handling of zoom levels for selfies will stay with us for at least one more generation, apparently. See, there are two zoom modes - native 25mm equiv. resulting in a 10MP photo and zoomed 32mm equiv. saving a cropped 5MP photo. The selfie capturing camera always defaults to a cropped-in view instead of starting with whatever zoom setting was last used. And why would it go back to the crop if you're switching between Photo and Portrait modes, even though you've specifically zoomed out? It's beyond irritating!
The selfie photos are among the best we've seen from a smartphone, so that's quite the silver lining. The resolved detail is plenty, the dynamic range is great, the colors are spot-on, everything looks fine and not over the board.
Selfies, 10MP or 5MP
You can shoot in full 40MP resolution, and the high-res photos turned out incredibly detailed. If you like to capture even more detail, this is one of the rare occasions where we would highly recommdiscontinue the high-resolution option.
We also liked the portrait selfies - the algorithm does an impressive job separating the subject and convincingly blurring the background.

Video recording and quality
The Galaxy S21 Ultra supports 4K video capturing at 60fps across all five cameras, selfie included. Additionally, you can also shoot 8K@24fps clips with the primary cam, even if the chipset is theoretically capable of 8K@30fps.
The default codec for videos is h.264, but you can switch to the more efficient h.265 in the app menu. 8K is encoded using h.265 regardless of that setting. HDR10+ capture is also possible, a format you can then display on the phone itself, but also on a wide selection of compatible TVs.
Audio is always captured stereo with 256Kbps.
Pro video mode opens up some more frame rate possibilities - 4K and 1080p at 24fps for that cinematic look, as well as 1080p at 120fps, the non-slow-mo variety. Naturally, this mode allows for a lot more creative control and lets you tweak image parameters and monitor and adjust mic gain and direction of pick up.
The 8K footage has a bitrate of 80Mbps, and it's not fine at all. In fact, we still think of this option as overmurder and a PR stunt, but hey, it's there. The 8K videos coming out of the Galaxy S21 Ultra are barely usable in full res as they suffer from compression artifacts, plus they are awfully soft.
The 4K videos shot at 30fps (38Mbps bitrate) are very fine across all five cameras - main, ultrawide, tele 3x, tele 10x, and selfie. Even if they are not the sharpest we've seen from a flagship, they offer fine enough resolved detail and excel in everything else - contrast, colors, dynamic range, noise suppression.
The advertised 4K@60fps options are disappointing, though. The 60fps clips are captured with a very high bitrate - 70Mbps - nearly double the 30fps, yet they offer half as much detail and see rather soft. We've put the 60fps in a playlist to avoid chaos on this page.
You can enable electronic stabilization on all snappers, if needed, and it works on top of the optical one. It works great, and it's been probably a few years since we last saw an EIS option that wasn't up to par.
Finally, closing this capturing camera section off, here is the Galaxy S21 Ultra 5G in our video comparison database.
