Tim,
After thinking about it a bit, some of the things I would really like to see documents/samples (or built-in solutions) for.
- Doing this with WMF or other webcam/capture devices as well as PRO cards.
- How to sync the unreal framerate to a video source without needing to use a PRO card.
- Proper way to enumerate/configure the video so it will work right when the hardware (webcam, capture card…etc) being used is changed.
- Proper way to get input from multiple trackers and route them to different pawns/cameras.
- A clean way to delay ALL the tracker data so it is in-sync with the video (ie: compensate for latency/delay in the video capture)
- How to properly setup the Cine camera to emulate some common cameras and fix up their lens distortion (ie: logitech 920 webcam, GoPro…etc)
- Best practices for recording the output from unreal (OBS sometimes records black or tooltip text instead of the PIE or editor viewport)
Hope this helps.
