Great, thanks. Linux: tick, C/C++: tick, QT: briefly used before - mainly need to look at Gstreamer/Openmax. Thanks.

General high-speed discussion / Re: First shots with the early bird camera!
« on: June 19, 2017, 08:07:43 AM »
Just plugged those numbers (75 cm focal length, f/4, subject 1 m away) into the depth of field calculator at http://www.cambridgeincolour.com/tutorials/dof-calculator.htm , using a sensor size of 1/2.3" (closest preset I could see) and you've got just a mere 0.7 cm depth of field. That's assuming you're viewing the image on a monitor with ample resolution at 10" wide from a distance of 10". Not 100% confident my assumptions are correct, but wow if they are.
That's a bit eye opening actually (no pun intended) - at least for me. Smaller sensors can get subject isolation from the background at much narrow apertures, optimizing the sharper middle ranges of zooms. Just need tons more light.

Oh yeah, the demosaic - forgot about that since I ordered the monochrome.
No rush for the sharper demosaic
Thanks.

To hit the ground running when the application dev environment is released, which languages, tools, 3rd party libraries/SDKs,... should one get familiar with?

What's the softness due to in most high speed videos I see?
Say for instance this loseless screengrab of the raw ducks mp4:
Link as forum software appears to scale up: http://i.imgur.com/FFM7luc.png
Is it from:
The duck at the back is obviously blurrier due to depth of field.
Or is this typical of normal shots in cameras before the camera sharpens?

Is it from:
- mp4 compression?
- quality of lens?
- insufficient lighting for faster exposure?
- focus?
