iPhone as a 4K Recorder/Monitor | Accsoon SeeMo 4K Review

Turn your smart phone into 4K video recorder plus on camera monitor-Accsoon SeeMo 4K.

Let’s review that. What’s good guys, my name is Oleg Nikitin. I’m sure a lot of you guys do know Accsoon SeeMo, the first generation, uh, device, let me say. But we have a better and newer device right here. It’s a brand new device, by the way. So here we can have a 4K, up to 30p signal got into your smartphone, and you can record this 4K signal as well. Unfortunately, you cannot feed 4K 50 or 60 fps, but still 4K 25 or 30p is great. So let’s have a look at this device. What we have here, what’s new, what’s not. So here we go.

Unboxing

And guys what you get in this white box. So first of all you have two cables. One is lightning to USB Type-C and the other one is USB Type-C to USB Type-C. Those are proprietary cables by Accsoon.

So here we have the iPhone 15 Pro Max, and it does charge via the NPF battery on the back and via this cable. So also, here on the body of the device itself, we have a cold shoe mount. It’s made out of plastic, but if you be careful enough you won’t have any issues with that. We also have an SD card slot for the big SD card, the standard one, and you can use it as a card reader to basically transfer footage from your iPhone to this SD card. And it is pretty nice. You cannot actually record onto this SD card, but as a card reader, why not? You simply go into the files app and use it as a card reader.

As I said, we also have the 5 volt output if you want to charge some other devices like the Sony ZV E1 with the cooling fan. If you want to charge the fan simultaneously from this NPF battery, it’s a nice solution so you won’t have any overheating. And also guys right here we have the HDMI in and you get the signal from your camera to this device.

You can also separate the phone holder and the Acsoon SeeMo 4K itself And you can also use it with the DJI Raveneye system, kind of a, you know, the same base plate as the Raveneye system uses. Or you can purchase a separate cage for an iPad and use it with the iPad as a monitor, as a display. Also in the kit, we get a pretty nice tilting mount with really nice system. In terms of, uh, you know, tightening this mount right here.

Separate  Acsoon SeeMo 4K

And guys, here are two images side by side. One is shot in camera to an SD card, and the other one is shot with the Accsoon SeeMo 4K into the iPhone. And as you can tell guys, the difference is not that huge. Of course, the bit rate is not that dramatic on the iPhone footage and if you are trying to push and pull the image to color graded a ton, you will have worse results than with the built-in codec. Of course, it’s an 8 bit video, but if you’re sending the signal in log format with the lot applied from the camera, like from the fx30 or zv1, or if you use a contrasty profile like as PPF, you will have pretty nice backup. Or you can simply put on the image HDMI display info onto the iPhone or onto the SeeMo 4K, let me say, and you can give your viewer understanding of what your camera says in terms of settings, autofocus, points, and so on.

And now let’s have a quick overview of the functions. They are pretty simple, and most of those functions came from the first generation. But still if you want to see those here we go. So here we have the black and white functionality,.

black and white functionality

A color functionality also the histogram which you can move throughout the whole entire screen.

The same applies to the RGB parade. The same applies to the Vectorscope. Here we have the focus peaking, and if you want to change the settings of this particular tool, you go to the top right corner. You hit the sign of the gear icon, and here you can change the different settings for different tools.

change the different settings

For instance, we can go into Vectorscope and make it a big one. So as you can see here, we have a big one or a small one. The focus we can make it a green blue and change the density or the peaking level. We can have multiple um tools on the screen.

make Vectorscope  a big one

So here we have the Luts. I don’t use the Luts right here. I use the lots in camera. That is why I’m not really bothering showing you the LUT section. Also here we have the zebras and we can adjust the levels of the zebras right here so we can adjust it to be less than 83% like so.

Then we have the false color tool with all of the uh, higher values on the left, which is nice. So here we have the audio levels here we have the different aspect ratios. And here we have the anamorphic squeeze and the grids also customizable. Here is the HDR mode. So you can dial in the HDR mode. If you are looking at an HDR image. Here is the flip mode. And here we have a still overlay, so you can kind of overlay two images. If you shot one shot and you want to make exactly the same shot, but I don’t know at night you can use this one.

overlay

So also right here we have the recording button right here. And you can see the remaining time and also the remaining storage of your iPhone. Here we have the live button so you can live stream from this device. I didn’t test it but as far as I know it works okay. It depends really on the internet connection. So here we have the frame.io and the uploading to a cloud service. I also don’t use those, so I cannot really tell if it does properly work.

frame.io

And here in the bottom right corner we have different settings like the transmission bitrate of 20 megabits per second. This is for the live stream as far as I understand the file record limit. And here we have uh, different settings and tools that you can add to the top bar. Or you can remove from the top bar by, you know, doing like so. So that’s basically it, guys, in terms of the functionality, it does have everything I ever need from an on camera monitor.

Conclusion

You have to be a bit careful with the display dimming. And if your phone gets really hot because it’s charging charging simultaneously, you can have display dimming issues, especially on the sunny day if the sun just, you know, smokes your phone.

So in this regard the back on camera monitor like 1000 nit monitor that I’m looking at right now will be a better solution because it doesn’t dim iPhones and smartphones on Android do have this dimming, uh, feature because they need to cool down. But all in all, as a pretty big and nice and bright and juicy OLED monitor, this is awesome to have because it’s very compact. You only need to bring an NPF battery, and this plastic construction mini holder and your phone is always with you, and now you can record 4K, and you can also use it as a card reader and have extra juicy battery, uh, to some other devices, which is great.

So in my opinion, guys this is an awesome product for the price. The price is $179. And I think it is a better solution than a cheap and not really good quality on camera monitor, because your iPhone or your Galaxy S20, four ultra, whatever. Pixel 8 Pro is a better display than a cheap and, uh, the same price kind of on camera monitor. That’s my opinion, guys.
