Title: WEIRD camera performance
Post by: elsa hoffmann on November 03, 2016, 07:37:19
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.

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,

Dave Hartman

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

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)

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

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  ;D ;D ;D

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

Elsa,

The internal microphone is going to record noises you probably don't hear while shooting. It will record almost and faint sound made by the camera. You have to get a microphone that is isolate in it's mount from the camera. You'll want a wind sock. Research and buy a mic that works with your dSLR that costs about $150.00 to $200.00 (USD). That's pretty much square one. There is nothing wrong with your camera.

Well if you have the time go to Nikon but the noises have everything to do with the microphone. The built in hears everything inside the camera and records it. As you use different features those tiny noises change so what the mic records changes. The mic must be soldered on the a circuit board and pushed into a hole in the body casting. It hears everything. It's a lowest common denominator device.

Buy a mic thing like Wallace with a hair dog!

Best,

Dave

Elsa,

If you watch this video it quickly covers many features of recent Nikon dSLR(s) and a few of the problems like sound recorded by the internal mic. It's worth a few minutes 12~15 minutes...

David - thanks - I finally got to view the video (which I already book marked hours ago - and it makes good sense.
I will probably buy a dog.
