Video Effect on Shutter Count
Mar 4, 2017 14:26:10 #
What influence does video recording have on shutter count on an Nikon DLSR's???

None when it comes to shutter count. Shutter opens then closes once you are done so one actuation per film. Counts as 1.
Now, is there a negative effect due to keeping the shutter open? I have no clue.
Now the influence on the sensor depending on duration... I have to assume it get warm if not hot, as it does with long exposure.

I don't shoot video so I know nothing except for a couple of on-line posts I just found. From them it appears that there is no shutter count actuated from shooting video (even though the shutter obviously has to open once). The frames per second setting for video is the "frame rate" and that is probably certain to be accomplished electronically rather than with separate shutter actuations on a DSLR because the DSLR's available fps settings are most likely rates that greatly exceed its frame advance rate capabilities.
Again, I don't shoot video so I have no idea how accurate the above information might be.

Long exposures do not cause the sensor to get warmer, never mind hot.
But with video, unlike a single long exposure, the CPU is active for the entire exposure time. The CPU uses significant power and unlike the sensor it therefore does get warm with use. For multiple single exposures the duty cycle is very low for the CPU, always giving it plenty of cooling time. For video the duty cycle is 100%, with no cooling time at all and it will get warm or even hot.

lmao @ the whale answer.
In one hand it does not get warm (if not hot) during a long exposure (which records a still image over a period of time) when in the other it does get hot while it records a moving image ALSO over a period of time.
The only difference is time. Usually shorter in long exposure but that is also a variable that can last minutes - as a video -.

Still not correct. The only difference is not just time.
The significant difference is the amount of time the CPU (not the sensor) is active.
The sensor can be 100% active for hours and will not warm up, because it uses no power.
The CPU uses power and will get warmer with time, if it is enabled. With video it has a 100% duty cycle but with single images, even with long exposures, it has a very low duty cycle that allows it to cool off.

Mirrorless cameras keep the shutter open all the time, and it doesn't kill them.

The general situation for DSLRs is that from the shutter / mirror up count a single video segment is the same a single still photograph. Overheating seems to be an old problem rather than one for more modern cameras. Each iteration of a modern processor typically gets more energy efficient. It would depend on the length of the video segment if a problem at all. Few people shoot really long segments, 12 minutes of HD video takes about 4GB of storage, so unless you plan to takes hours of continuous footage it is probably not worth thinking about.
If concerned about shutter actuations, then time lapse would be a bigger consideration than straight video.

Of course it does not kill them.
That they get warm is not even a question. It is part of it, same as any electronic part will get warm if a current is applied to them.
Why do you think the 'live view' has a time out? For fun or to preserve power?

As to the whale idiocies....
NOTHING is inactive if any current is applied to it, regardless of the whale claims. It is profoundly disingenuous to claim otherwise.
This is similar to say that a cell phone will not drain its battery if not used when not used to talk. The system is in 'passive mode' and will use less power but will eventually lose all power. Same for cameras. Leave one on for a length of time and regardless of you taking a capture or not the camera eventually will power down due the batteries being exhausted.
In camera when taking a video the camera is in constant 'power up' for many reasons from the active sensor to the active processor the camera 'live memory' and then the card recording - among other things like the live view -. This creates heat.
The sensor uses power. Anything that uses power gets hot. How hot is the real question. Can you cook an egg as you could in some CPU? Of course not.
This is a non debate created by the usual 'internet scientist'.
Why did I bring this up? Because when exposed to heat some pixels fail. These pixels would not fail in 'regular' picture taking (non long exposure).

Current is not something that is applied, voltage is applied and current flow depends on how much voltage and how much resistance.
There is no current of any significance flowing in the sensor while it is actively collecting photons, and thus no heat. That is a matter of fact.
Some small amount of current flows momentarily when sensor data is read. It is very little current and flows for a very shot time. Again a matter of fact.
Sensors do not generate heat when in use, and remain at ambient temperature.
A CPU uses many many times more current to operate than any other part of a camera. The CPU in a PC has to be cooled! The camera can't do that but the CPU is much smaller an less powerful. But it does heat up!

Jesus. You need to pay attention. The topic was shutter count.

Pay attention to detail. The topic is the effect of video, and that led Ron off into the twilight zone with inaccurate statements.

Ron doesn't live in the twilight zone, I wonder who does though?
The topic is the effect of video on shutter count. If you wait for sun up you may be able to see and think clearly...
Maybe those whale blubber oil lamps aren't what they used to be, maybe the fumes are clouding your mind....

Floyd loves to call others out on semantics. One thing he's good at: Finding the facts. Too bad he's like the person who can explain the mechanics of swimming, but can't actually swim.
