A typically imaginative and careful test, thanks. Your observation of a blur line is not something that I have seen anyone else mention. Meanwhile... you are also the only reviewer who has mentioned (previously) installing the guards with the little dot to the bottom. Others seem to install them incorrectly. What difference does that make?. Presumably it is important else Insta would not have emphasised it in the instructions on the box, which everyone but you seems to ignore...

Which stitching option did you use, Dynamic, Optical Flow or AI?

Very well done! Super helpful!

Love the side by sides. Thanks!

Damn your review is very detail and so easy to follow and understand. Wonder if you could make a video on how to handle insta x4 properly while recording 360 without getting interrupted on the stitching line

Thank you for answering my question. I have the X3 and use it when paragliding mostly (sticky guards are a must for this). We do fly in circles a lot to stay in thermals and climb, so later in editing if we keep the frame pointing one direction, the stich line moves and is more prominent and noticeable due to the movement. Another test you may do is to simulate some movements, like rotate the camera along the stick axis but keep the frame looking at a single direction. I guess the difference between x3 and x4 is probably only in software method of stitching, you can test that as well if you like another hint for testing ;)

Very interesting and helpful! Thank you!

One of the most useful reviews out there of the x4. Thank you! I’m really curious about the water to air or air to water transition on the stitching and how well the camera handles these situations without and with lens guards. Also with the dive case (in air and transitioning to water). Another thing I’d like to see would be the low light performance with walking and biking or vehicle speeds. Potentially with different lens guards.❤

thank you so much for testing it.

Im been waiting for this review, thx for the review

Thank you for this!

Liked and Subscribed. I appreciate good quality honest reviews over excitable hype. On my One X (which I still use for photography rather than video) I find the black rubber/silicone lens cap a great accessory. I've seen they make a similar one for the 4X. Do you know if this is designed for no lens guards, standard guards, or premium guards?

Great Video, thank you a lot 👍🏻

Great job. I was wondering if the lenses made a difference.

Good video, very helpfull! Thank you! (Subscribed)

HI there, great test One thing is missing thou - most of the time stich line is visible when you rotate camera mounted on the selfie stick - then you will see some visible crease on the sky/objects while moving forward or just walking. I've noticed that one on my setup as one of the lenses were a little bit dirtier and there was all to obvious where the stitching happen.

Nice video, the blurr line I often see on movement in security cameras using AI. May be related to the algorithm used in both cases.

Great Test, thank you! I have also noticed in other videos a noticeable stitching line. But as you showed really well, it is more a kind of blurriness. Definitely better in the X3. The X3 is almost seamless when it comes to stitching lines. The reason in the X4 could be a combination of the bigger distances between the lenses and the unfinished software. I wonder if this could be fixed in an upcoming firmware update?🤔

Thank you for this. It's very helpful. My X4 will be delivered Monday. A practical test (and I am absolutely serious about this) would be for someone to test which lens protectors better protect the lens in a chicken-foot tripod/monopod tip-over onto concrete or asphalt. Not for you to do it, but maybe someone that, for whatever reason, ends up with an extra X4. Or maybe by buying extra lens protectors, then attach them to a block with the same weight as an X4, and drops them (somehow guided) from the correct height. Anyway, again many thanks for what you've done.

Thank you

Did the x3 also have this? Is the X4 in your opinion worth the upgrade or not? Cheers.

Interesting collection of books👍

the bro knows what we want to see

Great video thanks for the comparison, do you think it’s worth upgrading from the X3 to the X4?

Want to see this compared to X3.

Thanks

While all three instances have the blurred band, the premium guards seem to be a little sharper at close ranges.

X4 vs ace pro please

Are the lens protectors the same for both sides, or is there a "Front" and "Back" one? (I think the old sticky ones were side specific")? And whats the minimum focus?

Can you do a sharpness comparison? Also checking for „ghosting“ / reflections when using the premium ones. I noticed that in several videos from other creators. It seems that the lens mirrors itself in the premium glass. Also, can you compare the x4 to the x3? On paper the x4 is better. More solution does not also means better images.

Very interesting and helpful! But I don't see the different, I mean the quality the same, so don't need to use premium lens

A really well controlled test that puts each under the exact same conditions might show significant differences, but with your manual test which is still representative of real world use. Not a problem then! What's a problem is this blurry like at the seam. I've never seen that with my One R and older Insta360 studio versions.

On the video with you walking towards the camera and pausing directly in front of it. If you look at your hat with the image paused, you can see the naked video has the least alignment issue where your hat falls on the stitching line. Moving to the standard lens guard there is slightly more misalignment on the stitch line - the two halves of your hat done align as well as they do on the naked. Finally on the premium lens guard, the misalignment is at its largest. The right half the hat is way above the left (looking at the image, not your right and left). Now, to see it, I believe you need to pause it. The books are less pronounced, but you can see differences in which letters are impacted by how much, but some of that could simply be the exact positioning as you walked towards the books and its alignment to the stitch line. So, I think for faster moving action, it is going to be more difficult to see, but in some scenarios you may be able to notice a difference. I think the flares and reflects, as well as dust are potentially a bigger deal for most people.

Currently watching still. Are these lenses waterproof? I wanna keep it on at all times thanks

Yikes, that's really bad, something tells me this can't be fixed by a software update.. there's just too much distance between the lenses. Thanks for the video! I was really going to buy this camera, but now I'm not so sure anymore.

can i connect a Sony WH-CH720N Noise Canceling Wireless Headphones Bluetooth to the insta360 X4?

All the same 👍

Can you use x3 Battery for x4?

As the book says... 😂

I’ll just use it with no lenses. When I’m not using it I’ll have the lenses on it.

Standard lens scratch far to easily.

most of the effect is the lens flare, seems no comparison about it as with lens guard will have severe lens flare..

You just trigger people with OCD😂

they all look the same no need for premium

Your forcibly animated husky voice stopped me to follow you inspite of good content.

Hi，I would like to get ur email to talk about the further cooperation with Anker.

Thank you
