Blackmagic Libre

Notes and scripts for using Blackmagic Design hardware with libre software.

No proprietary applications, SDKs, or similar are used.

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 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

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.
