\section{OBS Studio}
|
|
Notes.
|
|
|
|
I have the Blackmagic connected to OBS Studio live via USB to HDMI converter. Before I was re-encoding it and restreaming it to OBS. In this case, I have it on the OBS machine itself, a panda board. So Camera -> HDMI -> USB -> panda -> OBS Studio -> stream out. This way the latency is near realtime-ish too. Works quite well, for the bit I've tested.
|
|
|
|
This Blackmagic 6K, being able to use any lens, and can stream out 1920x1080, is the best "webcam" setup I've used.
|
|
It's also good for a lot of other reasons, of course. But with the image quality detail directly from the sensor, and being able to use "any" lens, is so nice.
|
|
|
|
|
|
This is cam -> hdmi -> usb -> computer -> obs -> restreamer (lan) -> owncast (wan)
|
|
|

\section{Kdenlive}
|
|
kdenlive can read Blackmagic 3D LUT files.
|
|
Cool, so if something was shot with "Film" setting, I can load it in KDE, apply a LUT filter, load the Blackmagic Film to Video LUT and it all looks magically nice.
|
|
|
|
Using kdenlive a bit. Happy to see that Blackmagic LUTs work, kind of like magic as name says.
|
|
But the LUT conversions provided are all Film to XYZ. So it may be best to shoot in Film mode to begin with, for most flexibility.
|
|
As there are four (maybe 5) LUTs available for Film -> Video etc conversion.
|
|
On "gamma" one that looks spectactular.
|
|
|
|
kdenlive can read the Blackmagic .mov files, but not .braw.

|
\item I think the BRAW format is a video HDR format (e.g. takes each photo at multiple exposures).
|
|
\item Natron can import BRAW, but requires propietary sdk bits.
|
|
\item Audio streaming via HDMI from camera works too.
|
|
\item I can tether via the camera and Darktable via USB.
|
|
\item But no live pic. Maybe cuz HDMI at same time (?).
|
|
\item Ya, USB-C is USB PTP, but no live view.
|
|
\item Can't copy images via PTP either. At least it sees it; sort of a start.
