How to modify the SDR trim after the Dolby vision analysis
After applying the Dolby vision analysis from HDR to SDR. Is it possible to modify the SDR trim using the usual grading process (the black magic panel instead of Dolby vision tools, creating extra nodes, new power windows..etc).

    Hi there! Unfortunately, there's not a way to do this as none of the default controls outside of the Dolby Vision panel would influence the metadata. Likewise, any changes you make after the analysis outside of the Dolby Vision panel would require you to re-analyze the content. Typically we'll see colorists doing these sort of power windows, etc. before the analysis is run on the HDR master.

    You can find more info on the trims here:
