We have tested the following HD-SDI converters and they are compatible:
- Atomos Connect HDMI/HD-SDI converter
- BlackMagic Design Mini Converter HDMI to SDI
- Datavideo DAC-70 UP/Down/Cross Converter
The supported resolutions are dependent on what these converters can support. For example we have found that using 720-120 outputs [720p (progressive) and 60 fps] successfully.
