Insta360 X3 vs X4 vs RS 1-Inch Sunset and Low Light Shootout! Which camera has the least noise?

Since the FOV was dewarped (zoomed in a bit to show noise), I chose 1080p as the exports because the actual resolution is barely HD for a reframing of a 5.7K spherical video. Also I shot the X4 on 60fps by accident, but I don' think it made a big difference because the shutter speed was all the same.

Wow! I actually think the stabilization and contrast look the best on the X4 at night. And I even like the contrast/detail more on the X4 during the day. Thanks for making this video.

I can't find a starlapse comparison between X4 and 1 inch ANYWHERE

Did you de-noise in post? Great comparison. Please if you could run a test with 24fps at night I would appreciate it!

[hybrydsanity]

nice honest and accurate comparisons, I have an RS 1 inch never bought an X3 but I am thinking about an X4, obviously the 1 inch would be better for low light and the X4 for more action based things and effects like slow mo and time lapse type effects. thanks

Nice vid bro.
So what is your conclusion ?

[seahog]

The aperture number is relative to the sensor size. The given aperture size (size of the physical opening in the iris that can be expressed in millimeters squared or, usually, as a diameter of a round opening) will give you higher aperture number for a sensor of a bigger size while the amount of light that it is letting through stays the same (as the opening in the iris stays the same). Hence the 2.2 aperture for a 1 in sensor may be physically wider than a 1.9 aperture combined with a smaller sensor. I'm speaking generally because I don't know what size is the x3/4 sensor and, in all honesty, I would need to dig deep in some photography textbook to find the proper formula for the aperture number calculation. You can also think about the physical size required for a 2.8 aperture professional camera lens (huge sensor relatively speaking) and compare it to the 1.2 (or something ridiculous like that) aperture of your cell phone lens. It should be pretty obvious which one is able to let more light through. The fact that the phone camera lens number looks so much better is simply a result of it being combined with a minuscule photo sensor.

No footages with all 3 cameras with auto WB or the same WB.... Can't be compared in that case...

Be careful—the RS 1-inch 360 vertical batteries have been unavailable for some time now. We're stuck (or Boeinged).

One RS will have less color out the box but better detail due to the bigger sensor, but if you try to do anything moving with like a sport, that’s where you’ll see the One RS not keep up with the others, which are true action cams. But I still do pro work on the One RS only but I’ll see how to work in this X4.

How do you manage to get such bad shots from your X3/

[haneko]

I guess i dont understand why you are using 1080p from the x4 no one is going to use that when they can get 2.7k. 1080p looks horrible in todays standards.

the fact that you have the cameras configured differently makes the whole experiment for naught but the way you talk and deliver your commentary makes the video unwatchable.
