WEIRD camera performance

[elsa hoffmann]

Well I am totally confused

Camera on tripod, timer set - all I did was press the button - as you can see - I got 2 different formats, the images before were fine - then one mishap size wise - then back to "normal" I checked - my raw images differs in size (obviously - so I didnt crop by accident)

Any clues??

One is a still in video mode, the other is not.

[elsa hoffmann]

Excuse my ignorance - since video is not my strong point....
How would one achieve that  - in other words - how did I get to do that?

The cropped image looks like in 16:9 format.  Weren't you in Live View mode?  If you accidentally hit the movie/still select lever around the live view (Lv) button, your still image could be in 16:9.  My D750 behaves that way.

Thanks Akira - it might have been just that!
oy driving me nuts.
I am also having issues with making video - there is a constant "clack" during the video and also sometimes it hunts... weather it is in S or C mode. I need to test it again before letting Nikon check for me.

The auto focus of Nikon in video mode is generations behind Canon unfortunately, needless to say about m4/3 cameras.  You cannot expect too much in this regard, even from the current models.

Elsa,

This video covers issues you note above. You might give it a try...

This same reviewer might review the D750 also. Anyway AF and noise recorded by the built in mic, also noise while changing apertures.

I only dabble in video so I can't offer much advice. I do think the noise you are hearing is probably normal. One of the first things you probably should do is buy a mic that is isolated from the sounds of the camera. Nikon makes one, the ME-1 Stereo Microphone for about $137.00 (USD). I'm not recommending it just noting that they make it.

Best,

Separating audio from the video recording is a must if you hope for a clean material to work with.

Shaking the piggy bank is going to be too slow. Get a hammer!

I think what I have here is a problem which doesnt appear consistently - hence my problem with it.

the clacking noise is mechanical - and nothing to do with the microphone.

I shall take it to Nikon for a check over - and THANK you for the video link - much appreciated

btw - Mark Wallace bought a a microphone thingie for less than 100$ while he was here - and we used this for some video - only fits on hot-shoe - but it worked unbelievably well. One of those with a hairy dog around the Mic (or is it a cat)

[Erik Lund]

It's a cat
External is a must for most situations indeed

[elsa hoffmann]

For my purposes (at THIS stage), I will exclude sound on my website  - but I am keeping notes of what you all say as obviously my situation can change. I mean one day I can have a youtube teaching channel

A lens changing aperture or an AF motor focusing may be enough to give a "clack" sound in a video, and microphones are VERY sensitive. You should show the video with the "clack" to the repair technician. Maybe he/she can help you determine, if it comes from normal operation or from a technical problem or malfunction.

This appears exactly what is happening. I had the camera on S, and it acted as if in C mode. Switched to C mode - same issue - switched back to S mode - and no more clacking. I am wondering if it is getting stuck internally on C mode - hence the problem

Now sit down and have a drink
