With the massive shift to file based delivery you need a file based legalising solution. Playout and recapture is one route but its defeating much of what filebased output saves.
A proper grade is key to ensuring levels are legal to start with of course. Then avids safe color limiter with 422 selected (no point in legalising with it not working its hardest) but experience shows some content xan still be illegal even with the safe color limiter applied. That then needs manual correction.
The change in codec is often the issue so dnx185x to AVC intra as we need to gor UK deliverables can throw an issue.
We have tge AQC of the final output as a check for Gamut errors and more and an eyeball QC of the final timeline with scopes etc as the human check.
Worth noting that there are alternatives to the safe color limiter that offer more broadcast options like R103 and even soft clippers. Be good if the Avid safe color limiter was upgraded to offer similar options. And even better if it had a mode that could do the limiting so that the codec change to follow was safe as well.
