After some fits and starts, we elected to go with the BlackMagic Intensity Shuttle with the USB 3.0 interface. I'm not going to create an entire tutorial here, just the final configurations that we found to work for us. The settings that we used may not be the only ones that work - we have not yet tested every configuration but here's what we found. We used a Raspberry Pi 3 B with Pixel (did this in July 2017 so as this thread ages, the information may become inaccurate).
Download and install the BlackMagic Desktop Video Installer from the BlackMagic site. At the time of this project, the download was version 10.9.3.
Configure the Intensity Shuttle, the BlackMagic Media Express and the Raspberry Pi as follows.
Program: Desktop Video Setup
Video Input HDMI (auto selected if only HDMI input is connected)
Output Format – as desired – best bet 1080i60,
Select - Remove Field Jitter on Pause
Conversions – Input: None, Output: None
Program: Blackmagic Media Express
Edit > Preferences
Project Video Format: 1080i60
Capture File Format AVI 8-bit YUV
Capture from a YUV source (should be selected and grayed out)
Select capture paths
Stop capture if dropped frames are detected
Stop playback if dropped frames are detected
Use Anamorphic SD 16:9
Continue playback when in the background
Set deck to _5_ second pre-roll for cueing
When capturing us a _0_ frame timecode offset
Wen mastering us a _0_ frame timecode offset

In the hdmi settings area:
Code: Select all
If you're going to record for a long time, screen blanking can be a problem. Install the screen saver, then disable it (I know, weird but that's the way it's currently handled).
Code: Select all
hdmi_force_hotplug=1 hdmi_group=1 hdmi_pixel_encoding=3 hdmi_mode=5
Video captures are huge! If you capture enough video for screen blanking to be a problem, you probably require access to one heck of a storage array. Our first test was a one minute, seventeen second capture that took over 9GB. We imported into our editor and rendered it out to be of a more manageable (re storage) size.
I'll be happy to answer questions if I can.
