The davinci limiter seems to do the trick. But adding supers, flares and comps can change that.
We just finished a McDonalds TVC (35mm/red to resolve to smoke) the final output on the smoke (via AJA) was showing serious gamut red issues (on bm ultrascopes) mostly on the maccas furry red end frame.
We run everything off to hdcam-sr via the Harris DL-860p legalizer. It’s bullet proof and never had a failure/ tech reject! Best investment we made (other than our davinci that is).
Cheers
