  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

KOMODO....

PS. Aaron, PDAF means phase detect AF and it's a tech used in Sony sensors and many others which uses multiple pixels on the sensor dedicated to AF capabilities. DPAF is dual pixel AF which means every pixel on the sensor is sort of split into two, with every pixel capturing image data and doing AF work. Canon has been pushing this tech a lot. You can learn a lot more on the web :)

What is the difference between PDAF and DPAF?
Click to expand...

PDAF is using phase detection "which creates two copies of the image, then adjusts the lens elements until the two images merge (that is, until they are in phase). The main advantage of this type of autofocus is speed. " (source : https://www.dxomark.com/glossary/pdaf/)

On DPAF (Dual Pixel Autofocus), "each pixel has two photo diodes which can operate separately or together. Each diode has a separate lens over it. When light goes through those lenses and hits the diodes, the processor analyzes each diode’s signal for focus and, once focus is achieved, the signals are then combined to record the image. Each pixel on the sensor, then, has a dual role.

That dual role is what makes DPAF sensors different. In other kinds of imaging sensors, some of the pixels are used for focus and the rest record the image, but none does both.

In Canon imaging sensors, 80% of the pixels (horizontally and vertically) play that dual role. The sensor on the EOS 5D Mark IV, for instance, is 6720 x 4480 pixels. At 80% coverage (5376 x 3584) more than 19 million pixels have DPAF. By comparison, the Sony a7R iii sensor is 7952 x 5304 pixels and has 399 phase detection auto focus points.

While mirrorless cameras have been using phase detection auto focus in imaging sensors for some times, DSLRs typically use a separate phase detection auto focus sensor for focusing while the mirror is down and the viewfinder in use, and switch to contrast detection auto focus on the actual imaging sensor when the mirror is up and you’re using Live View or recording a video.

And video is where DPAF can really shine, providing quick and accurate focus without the lens zooming in and out seeking focus. DPAF also makes following and keeping focus on moving subjects much easier and more accurate. And, you can easily manage focus and switch between subjects while shooting video using the touch screen in live view. For still photography, you can tap anywhere on the LCD screen on the back of the camera and get quick, accurate focus."

I prefered to search, copy paste some answers and link to the sources as I'm not an engineer ;)
What I can say is that I worked a lot since 2016 on shoots with a Canon C300 Mark 2 (I'm mainly an editor, director and writter but on small corporate stuff I'm also camera operator) and its DPAF is quick, accurate and face detection works really well. It's obviously not perfect and you can find yourself in situations where it doesn't work as you would like, but 99% of the time it worked fine for me AND just last may, I was on a gig at Cannes Film Festival doing interviews on that camera and the other guy was on a Sony A7III and its PDAF was also wuick and stuff BUT NOT AS QUICK and not as precise (you can see it going a tiny bit back and forth before nailing the perfect sharp focus).

Hope I could help ;)
 
So essentially these are digital versions of parallax convergence optical rangefinders.
 
I could go for a Friday teaser image or spec...:cheers2:

NDI is a neat zero configuration IP video network protocol. It could certainly be used to WIFI stream video from a Hydrogen phone to iPads or other network video monitoring devices on set or for wireless multi-cam live streaming production of events. Panasonic robotic IP production cameras have it built in. Newtek makes IP production switchers.
Komodo might not directly support wireless video streaming, but with the phone attached it possibly could. The app is a free download. I have it on my iPad.

MIPI CSI-2 would be more clever than NDI. And if it’s CSI-2 Komodo will do a few slick tricks that no other digital cinema camera can do right now.

Very different protocols for different purposes. NDI is an Ethernet network configuration protocol that automatically detects and establishes VPN links between NDI devices over local or wide area networks.
It is data content and bandwidth agnostic. I don’t think NDI is what would be used for the pogo pin data interface on Komodo.
You could theoretically run MIPI over NDI.
Panasonic’s NDI enabled robotic cameras support PTZ controls, tally, and camera setup via Ethernet as well as video and audio content.

With MIPI - the Komodo could be connected to a mobile device which could not only see and display the image from the Komodo sensor (processed by Komodo) - (the mobile device’s processor would see the video stream as if it was the stream from the mobile device’s camera) - it could live stream - it could record H265 clips and push them to the cloud - and the mobile device connected could “serve” the image to other mobile devices. #justsayin
 
About the same time Sony will announce a A7SIII.... I love competition! :001_cool:

Who knows...I *think* Jared has mentioned it's still months away? So maybe 1Q 2020?

What's a bit worrisome about this is if BM or others drop another update to their cameras. BM's already listed BRAW at 8K, which should indicate what's coming. If there's a Pocket 8K full-frame, that's surely gonna be a big splash.
