Why do 5.7K and 8K Insta360 X3/X4 photos/videos look so bad?

Leave a reply

For the search engines…

I see this question come up over and over (and over and over) again on discussion groups (Facebook, REDDIT, etc.). Folks see “8K camera” or “5.7K camera” and expect that will be better than an HD camera or 4K camera.

But not with a 360 camera.

With a normal camera, you have a lens recording a square/rectangular image. An HD camera will record an image that is 1920×1080 pixels. Those pixels are used for the entire square/rectangular image.

But, a 360 camera with two lenses takes its resolution and divides that by two — one for each lens. An 8K Insta360 X4 camera is therefore shooting a 4K image out the front lens, and a 4K image out the back.

BUT, instead of shooting straight ahead, it is a wide angle fisheye style image that is actually capturing everything in front, above, below, to the left and right of that lens. The back lens is doing the same.

When you think of it that way, the number of pixels that would be for the “forward” view is a fraction of the pixels you would get with a normal non-fisheye single lens camera.

Here is my quick doodle:

Now, reality is actually much more complex than this simple drawing, but the end result is you an “reframe” 360 footage to be a view in any direction. If you only use those six main directions (forward, backwards, left, right, up and down), you are dividing the pixels of that 8K image in to 6 smaller images. If 8K video is 7680 × 4320, then each view is closer to 1280×720 — which you can see is below “full HD” of 1920×1080.

So even with an 8K 360 camera, what you get in any specific direction is still not going to be as good as a simple HD camera that only records in one direction.

(And yes, I know the reality is much more complex, but this is just greatly simplified to help new users visualize how it works.)

Until next time…

Insta360 X3 versus Insta360 X4 in low light

Leave a reply

Updates:

  • 2024-04-26 – When I did this test, I recorded an 8K run, a 5.7K+ run, then 5.7K. I could not tell which video was which from looking at the info inside Insta360 Studio. I now think the #1 pass was in 5.7K+ mode. I will have to redo all of these ;-)

By request, here are comparison videos of the Insta360 X3 and Insta360 X4˘cameras recording in low light conditions. The recording was made at sunset, and the light level was low enough that the X4 displays the warning that it is too low for shooting in 8K.

But I did it anyway.

In the first test, I set the X3 to 360 mode and 5.7K. This allows reframing and exporting to HD. For the X4, I set it to 360 and 8K. This allows reframing and exporting to 4K. This obviously should make the X4 side have more detail, but what will it do to brightness of the video?

X3 5.7K versus X4 8K

X3 5.7K versus X4 5.7K+ (I think)

For the next test, I did two recordings with both cameras set to 360 5.7K+ (I think). In both cases, the reframed video is exported as HD. This was the mode the X4 tells you to use when recording in low light.

Test #1:

Test #2 in normal 5.7K mode (unless I have #1 and #2 mixed up):

Is one better than the other? You can certainly see alot of stabilization glitching going on at these low light levels.

To be continued…

I also repeated these tests at 24 fps (to see if that really does increase low light performance) and some other frame rates, but one of the files was incomplete from me hitting the button by mistake. I’ll go through the rest of my test clips, including some done in single lens mode, and create more comparison videos soon.

Insta360 X3 versus Insta360 X4 – side by side videos

Updates:

  • 2024-04-18 – You can download the mp4 files I uploaded to YouTube from my Dropbox if you want to see them without YouTube’s compression.

I received my X4 the day after release (thank you Amazon) . That evening, I went out and did a few quick videos with the X3 and X4 mounted side-by-side. For one test, I recorded video in single lens mode using the default 4K settings. For the other test, I recorded in default 360 mode then reframed and exported. Since the X4 comes with plastic lens guards, and since the built in tutorial shows how to install them as a first step, I put them on my X4. I wanted to recreate what a new user would most likely be seeing if they followed the on-screen instructions.

Single Lens 4K

When comparing Insta360 X3 single lens (4K, 30fps) to Insta360 X4 single lens (4K, 60fps), I think the X4 is noticeably better. In this video, the audio comes from the X4. The X4 also had the Standard Lens Guards installed. You will see some extra lens flare type stuff caused by these lens guards on the X4 that the X3 video does not have.

360 Video Reframed

I shot in default 360 video mode. The 360 footage on the X3 records in 5.7K, and the 360 footage on the X4 records in 8K. The reframe export option from Insta360 Studio is 3840×2160 (4K) for the X4, and 1920×1080 HD for the X3. This video is in 4K. The X4 appears to be a substantial upgrade.

Conclusion

My goal here was to do the simplest test I could, using default settings like a regular user would use. I set video and 150 (single lens) mode and recorded, and I set 360 mode and recorded. I then exported (and reframed/exported) in Insta360 Studio using the highest bitrate it offers (200 Mbits). I edited those videos together in Final Cut Pro X then exported to “HVEC” format (h.265) for uploading.

What do you think?

Insta360 Care, Extended Warranty, and FlexiCare

Leave a reply

I was a bit confused over the different extended warranty plans offered by Insta360, so here is a summary of how they work:

Standard Warranty

First, the camera comes with a one year warranty against defects. If it just doesn’t power on one day, and this was not caused by damage, that should be covered. But, if you got it wet, or dropped it, that would not be covered by warranty.

Insta360 Extended Warranty

This plan may be purchased and it will add an extra year to the standard warranty, covering the camera for 2-years. The price varies depending on the camera model. For the new X4, it is $49.99. For the X3, $45.

https://store.insta360.com/product/warranty_service

Insta360 Care (not for the X4)

This is a one-year “accidental damage” warranty. This is for covering a broken lens or cracked screen. The plan covers one repair during the one year of coverage. It is not available for the X4 — the X4 has a new plan currently just for it. This must be purchased within 15 days of activation of the camera.

https://store.insta360.com/product/care

Insta360 FlexiCare for X4

This new one-year plan is only $29.99 for the X4, and it covers accidental damage. It will cover two accidental damage incidents, but each one has a fee of $29.99 which covers shipping to and from the repair center.

https://store.insta360.com/product/flexicare-x4

Care versus FlexiCare

If you purchased FlexiCare and had to send your camera in one time during that year, it would cost you $60 ($29.99 for the plan, and $29.99 for using it that one time). This makes it more expensive than the Care plan for the X3.

BUT, the Care plan only covered one incident, so FlexiCare is basically a $90 plan for two repairs — if you use them both — or $29.99 if you don’t. That makes it a better plan if you do not ever need to use it.

Hope this helps!

Insta360 X3 and X4 file transfer comparisons

5 Replies

There are several ways to get photos and videos off of an Insta360 X3 or X4 camera. I no longer have a ONE X2, and never had a ONE X, so these may apply to those as well but I cannot verify.

  1. USB CABLE: Hook camera to computer via USB, mount it as a drive and copy files over. WARNING: I was doing this during a vacation, and it corrupted the microSD card. I just read about this happening to someone else (either on REDDIT or Facebook). They were able to use a file recovery tool to get their files back. In my case, the card had already been modified so some of my files were lost permanently. Because of this, I no longer use USB to transfer files directly from the camera.
  2. MEMORY CARD READER: You can take the microSD card out of the camera and then put it in a computer (via a microSD card slot, or using an microSD-to-SD adapter, or via some form of USB card reader). This is how I do it on my MacBook.
  3. VIA MOBILE APP AND ITUNES: If you transfer files into the Insta360 App, you can then hook your iPhone to a Mac via USB cable and browse the file system on the iPhone and copy files out that way. I expect there is a way to do this on Android as well.

Speed Comparisons

The X4 has a much faster USB-C connection and can copy in a few minutes what the X3 took 30+ minutes to copy. I ran a disk speed test on the memory card via a USB reader on my Mac, and then the same test via a USB mounted X3 and USB mounted X4. All were using the same Sandisk Extreme Pro 256GB microSD card.

I used the AJA System Test utility (available for Windows and Mac) to obtain these speeds.

microSD -> SD Adapter -> Apple USB-C Reader

Write: 67-77 MB/sec. Read: 88 MB/sec.

X3 via U-Disk Mode

Write: 18-19 MB/sec. Read: 22-23 MB/sec.

X4 via U-Disk Mode

Write: 50-55 MB/s. Read: 64-72 MB/sec.

Speed and Safety

As you can see, reading the memory card directly (assuming you have a fast SD card slot or a fast USB reader) is the fastest way to go. It is also safer, since if you are using a microSD-to-SD adapter you can toggle the “write protect” switch to ensure you don’t corrupt the card and lose any data. “Just in case.”

There is also a way to move files using WiFi — with the X3 being much faster than the X2. I assume the X4 will be even faster, but that is a test for another time…

Until then…

Insta360 X4 360 camera with 8K

Leave a reply

The latest 360 camera from Insta360 has been released today. You can watch their Apple-like presentation here:

I became intrigued with 360 photography quite some time ago. Apple QuickTime VR was the first time I ever saw it, and that software allowed taking a bunch of photos in different directions and splicing them together in to on virtual reality image that let you look in any direction. That started back in 1995 though I did not learn about it until a bit later.

I got my first digital camera in 1996, and experimented with panoramic “stitcher” programs that let me stand in one location and take photos in all directions then stitch them together to make a large panoramic image. This is why you can find odd “panorama” folders in my only photo galleries, like this one from 2002:

https://photos.atthefaire.com/Illinois/Geneseo2002/Panorama/index.html

This led me to experiment with “one shot 360” systems, such as the SurroundPhoto attachment I owned. It was a half-mirror ball on a stick that mounted to a camera, then you took the photo pointing up, capturing all 360 around you. Software would later de-warp this in to a 360 image that allowed you to look in all directions, including limited up/down.

You can read about the various 360 devices on my old One Shot 360 web page.

Here is an example of a 360 photo taken using the SurroundPhoto attachment:

360 Disneyland in 2005.

I was excited to later learn of a new 360 camera that had three camera lenses and promised to take these types of images in one shot, without any post-processing or klunky add-ons. I backed the 360cam on Kickstarter, and that was quite the fiasco, taking so long to actually ship that other companies such as Kodak and RICOH came out with their own (and cheaper) units.

Over the years, I have owned:

  • 360Cam
  • Kodak SP360
  • RICOH Theta
  • RICOH Theta S
  • Insta360 X2
  • Insta350 X3
  • …and maybe one or two others I have fogotten about.

In the early years, Insta360’s “ONE X” had inferior quality compared to the RICOH, but it had more “fun” features and effects that could be applied via the app. At the time, I did not want a device that needed an app. I just wanted to take photos and download.

RICOH remained the king of 360, with the best photo quality in their $1000-priced Theta Z model, but I was not interested in spending that kind of money on a better 360 camera.

I ended up with an Insta360 X2 and installed found it the funnest camera I had ever owned. I used it more than all the previous 360 cameras I had owned, combined. When the X3 came out, I upgraded to get improved photo/video quality.

The X4 is a slightly larger and heavier camera, but adds 8K recording, and thus needed a larger battery. With the release of X4, paid ads (er, “review videos”) have popped up all over YouTube telling us how great it is. After the X3 release, I learned many of these “review videos” were misleading – stating facts that were incorrect (either lying, or just uninformed), or mentioning how great a new feature was that — we later found out — did not even work in the beta firmware the “reviewers” were using.

We’ll see if the X4 lives up to the hype.

With the X3 price down for $399, I highly recommend it as a fun camera. For $100 more, the X4 may be worth it — but I’d wait a few months and see what real users think about it.

DJI MIC 2 transmitter works with Insta360 X3 with no adapter needed.

Leave a reply

12/9/2024 Update: For search engine visibility, this should also apply to the Insta360 X4 and the new DJI Mic Mini. I will update this post with more details when I remember to do so…

In addition to the new DJI MIC 2 working with the native iPhone camera app, it can also be used directly with an Insta360 X3 360 camera. With the previous DJI MIC or something like the RODE microphone system, you needed to use the microphone receiver and an Insta360 microphone adapter and have it all connected to the camera with a cable.

The DJI MIC 2 adds Bluetooth and you can pair it directly with the X3 just by pairing it as if it were AirPods. (I suppose Insta360 needs to update the firmware to just say “Bluetooth” if it supports devices other than Apple.)

This means a $99 DJI MIC 2 transmitter is all you need for remote audio for an X3 (or iPhone, with an extra step to switch the phone over to using it). There is no need for the receiver and cables unless you are wanting to use more than one microphone at a time (as far as I know, you can only pair one Bluetooth microphone at a time with the phone or X3).

Unfortunately, the DJI firmware disables local backup recording when using Bluetooth, and also disables the new noise elimination feature. This means if anything screws up with the Bluetooth connection, you are out of luck. Pity. Backup recording is one of the features that makes the DJI MIC so useful. Maybe this is a firmware thing they can change in the future.

Until then…

Changing default view for 360 video on Insta360 X2/X3 and others…

Leave a reply

When you export 360 video to a format that can be uploaded to YouTube, Facebook, or other online service that supports 360 video, you get a wide, warped video file that looks like this:

For the Insta360 ONE X2 and X3 cameras, the front facing camera (the one opposite of the preview screen) will be the focal point of the video. In this case, it’s the entrance of the Whalebone Grill in the Awa (water) realm of the new-for-2022 Lost Island Themepark in Waterloo, Iowa. (This new park is pretty amazing with its backstory and unique themes.)

But, what if you wanted the 360 view to default to a different view when first played? Unfortunately, the Insta360 mobile app and desktop apps do not provide a way to do this (currently; folks have been asking about it for years, so maybe one day…). Often, the advice is to put the video in a video editor like Premier or Final Cut Pro and change it there.

Some quick web searching led me to this REDDIT post with a comment from user glitch007 explaining a way to use the free ffmpeg utility to reprocess 360 video and set the initial view:

Set initial orientation of 360 video? (Insta360 Studio)
byu/glitch007 inInsta360

ffmpeg has command line options to specify the X/Y adjustments (yaw and pitch) for the 360 video export. You can import the original MP4 file and export it out as a new MP4 with the view changed. If, for example, I wanted my Whalebone Grill video to start with folks facing the seating area, I could change that and it would look like this:

The command line option to do this is:

ffmpeg -i "input.mp4" -vf v360=e:e:yaw=90:pitch=0:roll=0 "output.mp4"

In this example, “yaw=90” tells it to change the X view by 90 degrees. You could pass in 180 to make the video face the opposite direction. The “pitch” controls the looking up and down, and “roll” controls tilt (I believe; I haven’t actually tested it).

For the curious, the command line options mean:

  • -i … Input file.
  • -vf … Video filter (and any parameters it needs).
  • v360 video filter:
    • e … Equirectangular projection (the type of 360 format the video is in).
    • yaw / pitch / roll … Set rotation for the output video. Values in degrees.

glitch007 shared a timesaver where you specify a start and end section of the video and can quickly process just a snippet so you can see the results before doing the entire video. Using “-ss” sets the starting section, and adding “-to” lets you specify the ending second:

ffmpeg -i "input.mp4" -ss 00:03 -to 00:08 -vf v360=e:e:yaw=90:pitch=0:roll=0 "output.mp4"

If you run that, you’d get a 5 second clips covering seconds 3 to 8 of the video, and could look at that and see how the view is. This allows quickly making changes to yaw/pitch/roll to get what you want.

I used the ffmpeg command line utility to do this, but there may be Windows/Mac programs that put a graphical user interface on it, making it easier for folks to use. If you know of a good one, please leave a link in the comments.

Thank you, glitch007, for this tip!

Insat360 X3 now allows changing WiFi password

2 Replies

The Insta360 app has an option to change the password on the X3 camera. This may also work on other cameras, but I have not tested it. I have done a password change, but have not verified this actually did anything.

This option will cause the camera to display an authorization prompt, and once confirmed, you can type in a new WiFi password which the device will use.

I encourage ALL Insta360 camera owners to do this, as the default password is well documented and it allows anyone within WiFi range to access and download any photos/videos on the camera.

Insta360 X3 filenames are different than ONE X2 filenames

Leave a reply

I did not expect to need to make any changes to my Insta360 ONE X2 filename article, but it looks like things have changed in the new X3 model. The files are no longer compatible (reading a ONE X2 memory car in an X3 will report corrupt files), and some of the names have been changed.

A quick one is the LRV (Low Resolution Video) files. On the ONE X2, they would be named like this:

LRV_20220925_160926_11_072.insv.mp4

You could open that in any video player, since it was an MP4 file.

But on the X3, the LRV files are named like this:

LRV_20220925_160925_11_070.lrv

With the Insta360 Studio plugin installed, my Mac recognizes them as an INSV file but cannot preview them. Just like with normal .insv files, you can add .mp4 to the end and then at least open/view them.

More to come, I expect…
