# Video
|
|
The camera can acquire video in two main formats:
|
|
|
|
* `.braw`, a proprietary format from Blackmagic.
|
|
* `.mov`, a format that can be read freely.
|
|
|
|
There is some software available to use `.braw` files on Debian,
|
|
but they require using the proprietary SDK.
|
|
|
|
There is one unmaintained hackish project that can read `.braw`
|
|
with ffmpeg.
|
|
|
|
|
|
## Video Capture
|
|
The Blackmagic 6K can capture:
|
|
|
|
* Blackmagic RAW
|
|
* ProRes
|
|
|
|
|
|
*Blackmagic 6K Codec, quality, and resolution table.*
|
|
|
|
|
|
## Video Playback
|
|
The camera can be live-streamed out using a "standard" sized
|
|
HDMI cable.
|
|
|
|
Not all settings work for playback via HDMI.
|
|
|
|
The camera works, in some configurations, with these HDMI to
|
|
USB capture devices:
|
|
|
|
* INOGENI 4K2USB3.
|
|
* ANDYCINE USB3 with HDMI loop out.
|
|
|
|
The camera does live playback, in some configurations,
|
|
with the above HDMI to USB capture devices and these
|
|
Debian applications.
|
|
|
|
Confirmed works:
|
|
|
|
* mpv.
|
|
* ffplay
|
|
|
|
Doesn't work:
|
|
|
|
* VLC.
|
|
|
|
Here is an example using mpv with the INOGENI.
|
|
|
|
```
|
|
$ mpv /dev/video0
|
|
(+) Video --vid=1 (rawvideo 1920x1080 60.000fps)
|
|
VO: [gpu] 1920x1080 yuv420p
|
|
V: 00:00:02 / 00:00:02 (97%)
|
|
```
|
|
|
|
# Still Photos
|
|
The camera acquires still pictures in `.dng` format.
|
|
|
|
Out-of-the-box neither Darktable or Gimp can read these files.
|
|
They can be read by Rawtherapee.
|
|
|
|
|
|
# Hardware
|
|
Tested with Blackmagic Design 6K camera, acquired used.
|
|
|
|
|
|
# Software
|
|
Tested using Debian Bookworm (Testing).
|
|
|
|
Various applications used from Debian repos:
|
|
|
|
* Rawtherapee.
|
|
* Darktable.
|
|
* Gimp.
|
|
* Kdenlive.
|
|
* FFMPEG.
|
|
* mpv.
|
|

# Miscellaneous Notes
|
|
For further organization.
|
|
|
|
* Sigma zoom 150-600mm, "OS" set to "1" or "2" wanders.
|
|
Set to "OFF".
|
|
|
|
* When received, unit had 5 LUT files.
|
|
When reset, unit has 4 LUT files.
|
|
After shooting Blackmagic RAW (?), unit has 5 LUT files.
|
|
|
|
* Batteries from Canon DS5-R work with Cinema 6K.
|
|
|
|
* Power plug adapter (so you don't have to use battery in camera),
|
|
that works with Canon DS5-R doesn't work with Cinema 6K.
|
|
There is no exit port for the cable to go, which on the Canon
|
|
has a removable rubber cover.
|
|
|
|
* Cinema 6K consumes battery "fast". :)
