In this setup, the source signal is fed from the grading system, video router, switcher or playback device into an approved encoder. The RePro stream is then received by a compatible decoder, which outputs SDI to a professional display or reference monitor.
A typical signal path is:
SDI source → Encoder → RePro stream → Decoder → SDI output → Calibrated display
This workflow can be useful where the reviewer needs to monitor on a larger professional display rather than a tablet, browser or consumer screen.
Where used for colour review, the connected display should be suitable for the intended SDR or HDR review target and calibrated to the agreed production standard.
Before the session starts, the facility team, colourist or session host should confirm:
The SDI source is outputting the correct SDR or HDR signal.
The encoder is receiving the correct signal.
The RePro stream is configured correctly.
The decoder is outputting the expected SDI format.
The display is receiving the correct signal.
The display is in the correct calibrated mode.
No unintended LUT, tone map, scaling or colour conversion is being applied.
Audio, sync and frame rate are correct where required.
This approach can provide a more controlled viewing path, but it still depends on the full chain being configured and checked correctly. For colour-critical review, the colourist or facility team should verify the decoded SDI output against the primary grading monitor or another approved reference display wherever possible.
