Both smartphones are competent enough at taking videos but the Galaxy S10+ easily comes out on top with its plethora of shooting modes. The 7 Pro can only shoot with its main and telephoto cameras in 2160p at 30 and 60fps or 1080p at 30 and 60fps. Slo-mo videos cap at 720p@480fps and 1080p@240fps. In contrast, Samsung's competitor supports all those video modes in addition to Super Slo-mo 720p@960fps, normal videos using the ultra-wide lens and, of course, the so-called Super Steady shot. This one uses the ultra-wide angle to produce excellently stabilized video, almost action cam-like quality in 1080p resolution.
Anyway, we compared the two phones side by side in identical scenarios. We did the 2160p@30fps test on a tripod using the main cameras. It's clear that the Galaxy S10+'s video looks more pleasing because of the better contrast (this way colors pop out more) and superior sharpness. When it comes to dynamic range, both phones perform equally good.
We've also noticed the same effect with the aperture/depth of focus on the 7 Pro as we saw in the stills. Some of the subjects towards the edges of the scene lose detail while the variable aperture on the Galaxy S10+ adjusts so it ensures good uniformity across the whole scene.
We did a set of handheld videos again in 2160p@30fps but the test just confirmed what we've stated above.
In the telephoto department, the differences we've outlined become more prominent. The 7 Pro's telephoto video is just underwhelming, to say the least.
And here's how both devices deal with stabilization in 2160p@30 and 60fps. As you can see, there's no difference in the EIS on either of the competitors and stabilization is virtually non-existent in 60fps mode.
And here's a cool Super Slo-mo video shot on the Galaxy S10+ as a bonus.
Winner: The Galaxy S10+. Samsung completes the whole camera section with the last win in the video recording department due to its versatility and higher quality videos in general.
