Stacking Video Frames.

[Michael Erlewine]

I have a question for the Z9 owners. My copy has yet to arrive.

If I shoot 8K video, how easy is it to pull a single frame from a video?

Secondly, has anyone taken a video of an animal (or whatever) that is actually holding still or even a short video of a flower and tried the following:

What if while I am taking a video, I emulate focus stacking, and turn the helicoid from the front to the back of the subject. Is there any sense in then taking the series of frames and stacking them?

How possible is that?

I guess video is the quieter option, but with electronic shutter & no mirror, whats to stop you turning the helicoid whilst you do a burst of "normal" shots?
I'm guessing that might give you higher quality files to work with?

Meanwhile this is a fascinating area Michael.
My Pixel phone offers all sorts of single or burst modes for normal shooting.
I've used this both ways
- to select the best individual frame
- I've built animated GIFs from some of these bursts that worked really well
  (musicians on stage etc)

Also, don't your existing D7's allow you to try what you've asked about, without waiting for the arrival of the DZ9?

I could do that but want to try 8K and my Z9 should be here soonish.

Don't know if this is of interest to you Michael:

It is interesting. I have tried different methods of achieving this. I had a special focus rail built that instead of having a geared knob, had a smooth slide that allows you to, using video, to slide the camera forward in a very smooth fashion. I have yet to receive my Z9 and so am waiting. Actually, the Z7 II is a great camera (for my work) as well. Photo with the Z7II and the Nikon Z 105mm MC lens.

Overwhelming amount of details, very impressive rendering!

Impressive? Astonishing!

There is a nice 3-D "look".
How many frames for such a stack?

Probably something like 200.
