Re: [Avid-L2] Safe color limiters not clipping RGB black levels

 

you might need to dial down the video gain on your legalizer(say 1-1.5%) in the offending sections.
That is if you have the procamp option.

Subject: [Avid-L2] Safe color limiters not clipping RGB black levels

 
I'm kind of out of the online world these days, but I'm posting this for the online editors at the company I'm with.

We're having a problem with outputs from our Avid Symphony v7.0.3. (HP z820).  The international dept. of a network is kicking back our masters due to RGB chroma legality and oversaturation. We are outputting to HDCamSR at DNxHD 220x through our Harris DL860 legalizer. We are also exporting a file based same as source Quicktime with the Avid safe color limiter rendered and applied to the entire episode, and the result is always the same. Clips throughout have RGB levels slightly below the 0 mv limit but anything above 700 mv are clipped.  We have had the Harris unit calibrated, but the problem persists.  
Anyone have any insight as to why this might be happening?

thanks,
