The media could not be loaded. Yi 4K Action Camera UPDATE: As noted below, after less than 48 hours with the camera, while videoing my daughter's volleyball, the camera, no a tripod, was struck and knocked to the concrete floor. As you can expect, it was damaged, breaking the corner off of the front cover (the one through which the lens extends, and containing the words "4K video recording...." I contacted customer support, and asked to purchase a replacement front cover. I was told that Yi did not have these available. However, after a few back-and-forth emails (see below), they did decide to replace the camera under warranty. They DID NOT HAVE TO DO THIS, and I ask you not to expect them to do this very often (YMMV). They then asked for my Amazon order number, which I provided. However, they responded that they could not locate that order number, and asked for screenshots of my Amazon order. I provided these, and they informed me that the company from which I purchased was not an authorized reseller of Yi products, so they could not honor the warranty. They suggested I return the camera to Amazon and then purchase from an authorized dealer. I bought this legitimately through Amazon, with this listing (and Amazon's Choice label), and through Amazon Prime ("Sold by Electronics Club and Fulfilled by Amazon."). I was understandably, none too pleased. I contacted Amazon, and complained that they had connected me to an unauthorized dealer, without letting me know, and to my surprise, they offered to refund my purchase. Since the damage to the camera was caused by me, I insisted that Amazon provide a note in writing that they would accept the return, and started the refund process with them. Yi had provided an Amazon link to connect me to an authorized dealer, but when I looked it was this same listing. I queried Yi about which of the companies connected to this listing were authorized, so that I could re-purchase the camera, while the refund was in process (I have more events to video nearly every week), but did not get a response within a couple of days. So I called Yi to see if I could get that list, and was told that they did not have that kind of a list in the support department. They told me that they could not connect me directly with the individual I was corresponding with, but that he was the only one with that information, and I would need to continue my email thread with him to get that list. Well, given the delay in response, and the ticking Amazon return timeline, that meant I could return the camera, but if I bought another before ensuring I purchased from the right vendor, I would risk not getting the warranty again. I emailed my Yi contact again, and finally received a response. Yi decided to honor the warranty anyway, and shipped me a replacement camera! I must say that, in the end, this was excellent customer service. They definitely went above-and-beyond for me personally. However, not knowing which of the vendors listed here are authorized is a problem. I wish I had gotten the list to share with you here. ---- Original Review ---- I've gone through several inexpensive action cameras, researching a lot, and ordering a few. I'll include other items I liked and didn't below, but the one thing I noticed with all these cameras is the inaccuracy of the advertised video modes, both in resolution and frame rate. The Yi 4K is about double the cost of the previous camera that claimed similar modes, but that camera didn't deliver. The Yi 4K is close enough for my purposes, but not quite perfect. As for resolution, those appear to be standard: 4K/UHD is actually 3840x2160 2.7K is actually 2704x1520 1080p is 1920x1080, etc. But frame rate is a different matter. The attached video shows many of the modes: * The video itself is 4K/UHD @ 60 fps (although I don't know whether Amazon will scale it or change the frame rate). Each input video mode was scaled (by my editor) to 4K/UHD, for the duration of each 20 second segment. * In the lower right of the screen is the "name" of the video mode, (mostly) matching the designation on the camera (although modes with "Ultra" in the name were abbreviated to "U" to save screen space). * The source video timecode is overlaid on the lower left. This lets you compare the frame number to the frame contents. (Due to the design of my editing software's frame counter, I had to put the timecode on the left to chop off a bunch of extra, unimportant text.) * In the bottom middle is an indication of the actual recorded frame rate (the actual number of individual, unique frames recorded each second). This should not differ from the playback rate (except for designated "slow motion" modes). This text is also color coded to indicate whether the mode matches what is specified. * The frame rate of each input video was also scaled to match the 60 fps (actually 59.94, but that difference doesn't matter here) during the first 10 seconds of each segment. (e.g. the timecode would count from XX:00:00:00 to XX:00:00:29 during the first second of a 30 fps input video, and each time code would be shown twice to match the 60 fps output video.) * The second 10 seconds shows the video slowed down to 1 fps, to clearly show individual frames. Comparing the video to the timecode makes it obvious when a frame is replicated (timecode changes, but content of the image does not). * Further, (most of) the media info (obtained from Media Player Classic, using codecs installed with K-Lite CODEC Pack) is overlaid on the first 5 seconds. The important items to notice there are the video's resolution and frame rate, the latter being highlighted. * Finally, some segments include extra information overlaid on the video. Each video clip was recorded with most settings at defaults/auto (e.g. WB, ISO, etc.). The field of view (FOV) was set to maximum (Wide), except for the unconfigurable Ultra modes. The lens distortion was enabled for all modes that allowed it, which was mostly non-Ultra modes. With respect to the frame rates, what the video shows: "4K/30" - Recorded at 30 fps, played back at 30 fps. (GOOD) "2.7K/60" - Recorded at 60 fps, played back at 60 fps. (GOOD) "2.7K/30" - Recorded at 30 fps, played back at 30 fps. (GOOD) "1080p/120" - Recorded at 60 fps, played back at 120 fps, causing the clip play twice as fast and run for half as long as recorded. (BAD) "1080p Ultra/90" - Recorded at 45 fps, played back at 90 fps, with each frame repeated twice. (BAD) "1080p/60" - Recorded at 60 fps, played back at 60 fps. (GOOD) "1080p/30" - Recorded at 30 fps, played back at 30 fps. (GOOD) "720p Ultra/60" - Recorded at 60 fps, played back at 60 fps. (GOOD) "720p/120" - Recorded at 60 fps, played back at 120 fps, causing the clip play twice as fast and run for half as long as recorded. (BAD) "720p/240" - Recorded at 240 fps, played back at 240 fps, but the image is dark. (GOOD) That's much better than other cameras (7 of 10). The last one I tested was accurate (GOOD) only on 2 of 7 modes. The actual image quality of these modes will take some further testing to be thorough, but so far, it is fairly decent. Some other cameras used very poor methods of scaling the data from the sensor to the video resolution, resulting in immediately obvious poor quality (see Nearest Neighbor Scaling). But the Yi 4K scaling is pretty decent on first look. I'll have to break out the resolution chart to get any more detailed, but I haven't done that yet (and I'm not certain how that's going to work with such a wide angle camera, anyway). Beyond frame rate, here are some other Likes and Dislikes: Likes ----- + Most frame rates are as advertised (at least the ones that are critical to me). + The individual files of long recordings, which are broken into ~3.8 GB h.264 files, are actually complete! This is not only the first action camera I've seen with this, but even my high end consumer video camcorders don't do this. They all require post-processing to join the files together (Google for AmateurResolveAndFusion), in order to avoid losing frames at the boundary, before loading the video into the editor. MANY KUDOS to Yi (or their silicon vendor) for this simple solution that saves a LOT of time! + Camera includes lens distortion correction. Obviously, there is some loss of data at the edges of the picture, but the lines are straight! It's not perfect (objects at the sides of the screen are a bit wider than they are in the middle), but unless your video editor has this feature, it's great to have. + Has built-in tripod mount, so no frame or case is needed (however, see last Dislike below). + Mobile app (at least for Android -- Yi Action) is much better than the one used by other cameras (XDV). ++ It doesn't crash (at least not yet). ++ It will update the camera's firmware, so you don't have to load it onto a microSD card (I think you can do that as well, but this is easier). ++ It reconnects with the camera well and fast, even after your phone goes into low power mode. (XDV usually requires killing the app, and often clearing the memory and starting from scratch.) ++ It displays the video image correctly (a bit of glitch sometimes, but great for framing) after reconnecting. (XDV video is blank.) ++ Has full controls for the camera. (XDV is limited.) ++ Has short cut buttons, including lens correction. Dislikes -------- - Not all frame rates are as advertised (see video). - 720p/240 image is dark, even with ISO at max (6400 -- see video). - Sound is poor. I haven't done much with sound (just noisy volleyball gym, so far), but what I've heard sounds pretty bad. There's distortion and buzzing, plus tons of noise. I did not include the audio with the sample video, but this was taken in a room where the only actual sound was a ticking clock, and the internal noise was so loud that the tick could not be heard on the recordings. - File naming, especially for 2nd and later files for long recordings (>3.8 GB) is very confusing (e.g. YDXJ0028.MP4, followed by YN010028.MP4 then YN020028.MP4). - Doesn’t do 4k Ultra (i.e. full wide angle) at 30 fps (only 24 fps) - No configurable/setable WB. Unfortunately, at least for the volleyball gyms I've used the Yi 4K in so far, none of the presets give anywhere near a decent picture. The Auto setting isn't too bad, but the nature of Auto is that it changes (not sure whether it will change during a recording, but definitely between recordings). So doing post-processing to correct the color means a different adjustment for every clip! A setting that allowed the camera to set the white balance while looking at something (in the middle of the screen) that is white, would at least let the color be consistent, allowing one adjustment (if necessary) to be used for all video clips. - Mobile app uses the same button to start/stop video. There is a delay, which seems to vary, so if you press the button, see that video hasn't started recording, then press it again, you are likely to have just stopped the video after it recorded only a few frames. - Doesn’t display correct field of view (FOV) on screen until the recording starts. The first time I tried this setting, I thought it didn't do anything. So I set my camera up to take in the whole volleyball court (using either the camera screen or the mobile app, it doesn't matter). But when I started the recording, suddenly the FOV changed! The lens distortion adjustment shows immediately, even if the video isn't being recorded, but not the FOV (Wide, Narrow, etc.). - The list of supported SD cards are too small and limiting. Not only does the list only contain the most expensive cards going, but the biggest cards on the list are 64 GB. I'm afraid to buy a 128 GB (expensive tier) card to see if it works. What about 256 GB? Yi could definitely help us out here by updating the list. - Connecting the Mobile app to the Yi 4K via WiFi disconnects you from any other data network. This means I don't get any app notifications, and can't access the internet, if I use this feature. (I realize this may be an Android limit with WiFi, but then I'd ask whether we can't use Bluetooth instead.) - No control over shutter speed in video mode. Again, with sports, I'd really like a faster shutter (I realize this will require increasing ISO) to freeze the ball better. The faster frame rate helps, but direct control would be preferable. - Does not take a fall unscathed. OK, well, this isn't fair. I video my daughter's volleyball games, and a ball ricocheted and hit the camera on the tripod, knocking it to the concrete floor. It was less than 48 hours old! (The sample videos were taken before this injury.) The corner of the front cover broke (plastic vs concrete). Otherwise, the camera works fine. I've now ordered and received an aluminum case (Amazon ID: B01LPWTX0E) to avoid further injury. (I looked for a replacement case or front cover, but so far, the only one I've been able to find has me concerned about whether giving my credit card information might be dangerous. Yi, if you're reading this, and you have an empty case, broken camera, or front cover lying around, I'd love to get one!) Maybe some of these Dislikes can be corrected with a firmware update. However, the Yi 4K is a 2017 model, and the newer (and double the price) Yi 4K+ is the top of the Yi line of action cameras, so I'm not sure how much work is still being done on this one. I still haven't tested other features of this camera, like EIS, YouTube streaming, time lapse, (don't care too much about voice control), etc. And I haven't really checked the battery life. I didn't buy an extra battery and charger, because I doubt even 2 would make it through one day of the volleyball tournaments (the longer they play, the better they are doing, so running out of power late might mean missing the championship game!). Instead, I've been using an external battery, connected via microUSB, to be sure the camera lasts all day. While not perfect, overall, the Yi 4K is very good. This one (unlike the last one) is definitely a keeper.

Style: Camera Only
Color: White Pearl
First impressions: The box is minimalist in design, with a small logo and title on the front and a large picture of the camera, and makes me think of a certain fruit oriented manufacturer. The box is 4" x 4" x 2 1/8" and the cover lifts off to reveal a tiny pearl white (in my case) nugget nestled within. It has a gorgeous, slightly satin finish and feels of much higher quality than most other action cams. Labeling and graphics are minimalist and add to the feeling of quality and sophistication (yes, I'm waxing slightly lyrical, but this camera has exceeded my expectations by a significant margin). It has a good heft and feel in the hand, weighing in at 3 1/4oz or 89g on my basic Ikea kitchen scales. Unlike many other GoPro wannabes, this camera comes with nothing in the way of frills or accessories. Clearly Yi believe that the inherent quality of the product means that they don't need to bundle a mounting harness for your pet dolphin or raccoon, or anything else for that matter - no waterproof casing, no handlebar mount, no selfie stick adapter. NOTHING, other than a six inch microUSB cable. Part of me wants to dock one star for that as even the GoPro units come with a housing and basic mounts, but you are saving a Benjamin and half over the black version, for similar or slightly better video quality (more on that later), so I'm going to let it ride for now. If you've never held an action cam before, the small size of such a unit will probably surprise you. These are unto Micro 4/3 cameras as those are to DSLRs, or possibly even more than that. This Yi 4K unit is a mere 2 1/2" x 1 5/8" x 1 1/8" including the lens bulge on the front. It features a standard 1/4" tripod mount socket on the bottom, a small speaker grille and dual microphone pin sized pickups either side of the power/shutter button. The battery and microSDXC ports are behind a well damped and well sealed door on the bottom, and the only other salient points are the 2 1/4" (diagonal) touchscreen on the rear, and the microUSB port on one side. To get started, you will need to peel the lens protection film off, insert the battery (do NOT try and peel the little plastic tab off the bottom of the battery, that is designed to make it easier to remove the battery at charging time - it is a REALLY snug fit), and press the power button on top. A short musical chime and a single LED flash on top confirms that the unit is powering up, and within two seconds you are greeted with the welcome screen. A moment of turning the camera this way and that will lead you to realize there are no control buttons - this unit has a touch screen for control of all settings and functions. A few taps on the screen will whisk you through the very brief "how to" and you will be left with the default "ready" screen. Insert a card, as I did, and you may get an error message telling you that there is a card error. You should probably power the camera off, BEFORE inserting a card, as I'm sure they probably tell you in the manual, but then who does that? By default, the unit is set to record 4K@30fps, with stabilization disabled (stabilization only available at 1080p and below). Unstabilized video looks pretty good, mainly because the camera is light and it isn't difficult to hold your hand fairly steady. Stabilization does make a noticeable difference, especially at higher resolutions, but you will probably be using more juice to do so (tests to follow). My blank 4GB card told me it could record a little over 7.5mins of 4k@30 video, so the likely 64GB card ceiling will offer around 2 hours recording time, which is probably more than the battery can handle. All in all, first impressions are extremely favorable, and should make this the best value 4K choice for most action cam aficionados. (Update 1) My camera came with v1.07 firmware. By going to the yitechnology dot com site, and heading to support I was able to find the firmware file to update it to v1.09. Firstly, check on the battery cover whether the tiny serial number starts z16v13L or z16v12L to select the right version. Then, simply connect the camera to your computer with the included cable, save the file as firmware.bin, directly to the root directory of the camera's card, disconnect the camera, and power camera on. You will be asked if you want to update firmware, and after confirming, the unit will take about thirty second to apply the update and then reboot. (Update 2 - 7.14.16) Puchased two 128GB cards from a certain local well known photographic store, but had very different results with each of them: PNY Elite 128GB MicroSDXC Card with Adapter -UHS-I, U1, up to 85MB/Sec (P-SDU128U185EL-GE) Inserted this card and powered up with camera set to 1080p@30fps. After a very brief SD card error message, was able to check settings and see it show up as 119.2GB of formatted space. This equates to 9hrs 8mins and 54secs of recording time of 1080p@30fps, or 4hrs 38mins and 57secs of 4K@30fps. HOWEVER - if powering on the camera in 4K@30fps, the camera will come up with an SD card error, and take 20 seconds to sort itself out. I did a brief test recording and there does not appear to be any frame dropout, so this card may cope with that frame rate (See below for more info). SanDisk Ultra 128GB microSDXC UHS-I Card with Adapter, Black, Standard Packaging (SDSQUNC-128G-GN6MA) Prior to testing, I would have put my money on the Sandisk card working right out of the box, and it being the PNY which needed fiddling with, but, surprisingly, the opposite was almost true. I have yet to be able to get the camera to recognize the above Sandisk at all. The PNY is recognized after a brief wait, but whilst it might be possibly to custom format the Sandisk in order for it to be recognized, out of the box the Yi 4K will not play nice with this card. (More info below). A note on 4K recording. One of the things I had looked for when picking an action cam was one which lived up to the specs it advertised. There are a lot of sub $100 4K cams around which purport to record 4k@30fps (well 29.97fps actually, but let's not get too geeky), but many of them will do that frame rate at 1080p and not at 4K. This one does appear to do so, possibly.... VLC (my media player of choice) shows the file properties as being the full resolution of 3840x2160 at 29.97fps, but that could just be what the camera has stamped on the title of the file. I will need to look a little closer at this as when I ask VLC to play the Yi's 4K video at full screen on my BenQ 4K display, it has black bars down the sides, and does not fill the screen. This bears further investigation over the coming week. >>> Further 128Gb card testing: Having sorted out a minor technical gremlin with my USB3 Card reader (it does help if, *ahem*, you plug it into a USB3 port), I was able to benchmark all three 128Gb cards I now have available. In addition to the two cards listed above, I now have the following: SanDisk Extreme PLUS Micro SDXC UHS-1 Card with Adapter (SDSQXWG-128G-GN6MA) This card was recognized immediately, and without an SD card error, the first time I inserted it in the Yi 4K. It is one of the approved cards recommended by Yi on their website, so it would appear that their testing has some substance, and if you want hassle free results, you should go with their list of tested and approved hardware. I have the Elite-X version of the PNY card on order (not on the approved list of cards, but more in line with the Sandisk Extreme Plus for speed), which should be here in a couple of weeks, and will update this review once I have it on hand. Benchmarks of the three cards are shown in the accompanying images, below, and whilst all three of them have sequential write speeds that are close to or above the 30MBytes per second necessary for high quality 4K recording, the Extreme Plus justifies its price by being almost three times that fast for twice the price of the other two cards. FOR THE MOMENT - If you want to avoid issues, refer to the list of approved cards at Yi's site. Update 3 Have just received a Samsung 64GB PRO Class 10 Micro SDXC Card (MB-MG64EA/AM) (the previous generation to what is sold currently). This is a U3 speed card, and works in the camera without error. I also updated the camera to 1.0.12 firmware and have found that the PNY Elite card which was previously 'quirky' is now recognized without an error message when powering up! I have recorded 20 mins of 4K30 and 4K30 Ultra footage, without issue. The Sandisk Ultra card, however, is still not recognized and must now be assumed to be incompatible. Kudos to Yi Technology for their diligence in continued testing and development. <<< >>> Accessories: I have just finished reviewing a third party dual battery plus charger bundle: EforTek AZ16-1 Replacement Battery(2 Packs) and Dual USB Charger for AZ16-1 and Xiaomi YI New 4K Action Camera (YI-90003) from YI Technology Overall impressions are highly favorable after just a few days of usage. The price of the bundle is made worth it by the pair of batteries alone, if you can put up with the minor quirks of the charger.
