Hi...

I have X-T30 II...

I try to record 4K video with Remote app on my iPhone, but it seems it always record just HD... That's a big deal... Any resolutions? Also focust point square don't work on iPhone screen when I shoot in video mode...

Thanx...

Oh yes, that's bad... I saw also the same issue debated here:

 

That man have good videos... Anyway, I am a huge fan of Fujifilm for years now... I mostly record myself, so using remote app would be great option I thought... Big deal breaker. How is that even possible for such a great brand, 4K is not supported to shoot with app? Isn't it just like, why it isn't possible? Isn't it just like, just a remote thing to press start to start shooting, I can't see why it isn't possible... Maybe we can contact Fuji to update the app?

 

Also focus control inside app is problematic - there is no control at all.

 

For now, I switch to my smart TV as a monitor for shooting via HDMI cable.... Anyway, It is good, but it could be better to have the controls in front of me via app...

It does seem like there should be a simple way to do this, but it will take some serious wifi equipment upgrades to do that, at least so I believe. Here goes:

First part:

The wifi chip in the cameras support the b / g / n standards so it theoretically can send / receive data at up to 100 Mbps. In real world conditions, that will be considerably slower -- just like a home wifi router.

The 4K Video Data Rate the camera supports is up to 400 Mbps which is already larger than the fastest possible wifi transfer speed. The lowest 4K Video Data Rate is 100 Mbps which might be feasible for transfer in ideal situations, but in practice, as noted, those ideal situations happen very seldom.

Second part;

So why not record 4K video to the card and send over 1080p video to the phone? This also seems like it should work. As an idea, sure, but in practice that is tricky. Think about converting some 4k video down to 1080p video on your computer. Most home desktop computers can do this, but it takes a while, even high end systems struggle when asked to do the conversions in real time, you need serious computing power to do the conversion on the fly, so to speak. That power is way beyond what is in the camera -- you would also need some serious cooling capabilities built in to handle the heat that comes rolling off of the chips while they are doing the task. This moves you up into the RED camera class -- very expensive.

So i think the 1080p transfer to the smart phones, etc. is the best current option out there.

That sound reasonable...

But I came from a different starting point. I would just need a control so that when I put myself in the scene and am far from the camera, I could adjust the focus from a distance of a few meters and press start...

So to speak - really just a remote control in the literal sense...

Will this work?

I think this is unacceptable. Sony has been doing this effortlessly in years considering they also have a very bad reputation on their software.

Perhaps you can show us an example or two where Sony's cameras have been transferring very high bit rate 4k data over b / g / n WiFi networks in real time to smartphone and tablets.

p.s. Welcome to the forum.

      X-s10 Fast shutting 20/30 fps crop ES

      By mapoett · Posted

      Hello. Thankyou,now Is all more clear: I have take some time in your link. Let tell you. I has totaly forget this machine have "compress picture option" and not Only "compress lossless" anyway not change the experiment. RAW  and this last two format look like same result about Number of recording picture. Can tell all results in this: in raw you can make 17 pictures for second. Is wrong. Is about One single Press and wait buffer. Full 30/20/10/8 not change. After 17 Need Press again. You not can Press before "redgreen light recording Is on".   With preshot you can have 25  are more 7 pictures . The story change Only in jpg shot only. In jpg at 30 you have 30 picture but redgreen light off very Fast so you can shot very quicly. At 20 shot Is about start look like infinite shot. 60. So the best performance are this last One  about Speed and recording picture after camera working witout big limit. I want take a shot about Italy cyclet Just for passion. I think i Will use this last setting.  After Need check when battery not are full change and ambient temp.  Anyway my cam look like exactly specific about you link. Im Happy my cam working perfectly.

      Hello from Iowa

      I do not use Flickr, so I do not know what their BB code is. All I did was copy the second link you provided, (starting at https: and ending at  _k.jpg — leave off the [img] and [/img] tags) and pasted it into the message. After a moment, a message popped up asking if I wanted to paste it as the image or as a plain link. I did this twice, the first time I had it paste in as the image and the second time as a link. Nothing fancy or tricky.

      So do I just copy the BB code from flickr and paste it anywhere on the page like other forums or is there some other trick I need to perform to get it to post?

      X Raw Studio Doesn't Create Drive for Camera When Connected

      By JovialLich · Posted

      All software is the latest between camera and app. All settings are correct on camera. I have both lossless and uncompressed RAW files on the card in the camera. I have been up and down every reddit thread to no avail and am losing my mind… I’m doing all of the right things. It even sees my camera. It just doesn’t create the “drive” for it (see attached image screenshot).  Please Help!

      X-T30 II Eye Sensor + LCD Image Display viewmode not working

      By grizzski · Posted

      Not sure how to delete threads, but I figured out what was wrong. In short, I was partially misunderstanding the view-mode's function. Also, the "+LCD Image Display" part requires that you have the Image Disp. setting set to anything but Off. Then it will display your last image on the LCD. If it's off, it's behavior will be exactly like the plain Eye Sensor setting.
