We did not find such a command

All right, this is for 4K without a plus.

[serg2337]

Modify the action camera YI 4K. The most important thing is that we will not need to change the lens and we will keep a wide angle of shooting. We make a convenient focus control and can enjoy excellent macro and near shooting. Link to videohttps://youtu.be/qtLxQbkaqn0

Itala2shoot everything in 4k

[webby]

I also play with modes.
The first mode on the latest firmware 4000 * 3008 25 fps On the Android TV Box, the ZIDOO Z9S does not want to lose the cut. Although the old laptop with jerks but plays.
In the second mode from above (like 4K 3840 Г— 2160 60 fps, since there is no camera at hand), but the sound is played with a periodic disappearance. There is a sound for a few seconds, then a few, and with a repeat until the end of the video.
Without any problems, the third mode from above is 4K 3840 Г— 2160 Ultra.

You probably never rebuilt the focus on action cameras
To get a normal sharpness in at least FHD, I'm not talking about 4K resolution ...
On the camera screen with its resolution, you will not rebuild the focus.
Well, except that for you in HD resolution, it can still go away

How to maximize voice clarity in blogging in the face of noise: city, railway station, etc.

I use an external microphone. I think this will solve many questions.

[Greenn]

doctorpit,
On the external microphone is some kind of background. I saw a movie, there a dude sculpted a sponge on a microphone, and stupidly with a rubber band)) And the sound was normal. Xs, can prokanaet, not tried

[AvalonNW]

Greenn,

Question: Is it possible to connect a non-native Bluetooth remote control to the camera, but a third-party manufacturer? Are there any advanced Bluetooth settings?

[gudron1704]

proximus, I tried some kind of remote control, to no avail.

[v_max]

proximus,
It is unlikely that yi has a very specific console protocol with a complex command structure.
And most of the remotes for android and ayos are just a bt keyboard for a couple of buttons

[proximus]

v_maxDak here to know how to connect other devices to it. For example with electronic stabilizer

[v_max]

proximus,I see no problems.
As if to a stub as such, you do not need to connect anything .. and you can also use the remote control to control the camera and your own yi-shny.

[proximus]

v_maxuncomfortable. When the camera turns off, the console does not automatically connect when turned on. You have to do it all over again.

There would be a script when you turn on the camera to start searching for the remote.

proximus,
Strange .. Maybe you just do not wait?
In fact, it should connect automatically.
Although not instant.

Maybe you just do not wait?

just as with wive)
the buttons on the camera simply do not respond within a few seconds. communication modules are not ready immediately.

a couple of weeks ago, blinded by the full:
I poked, poked the remote, blinked, and not a fig connect. I came to the idea of ​​replacing the battery, bought, inserted, again nifiga. it turned out that the console was priority to the body, because it was once paired with it. Long neighing shorter))
has nothing to do with the question. just a joke about inattention.
