| Sep 2, 2017 at 0:41 | comment | added | Michael Liebman | ±350 mV for the color channels is the full range. The spec doesn't seem to specify accuracy, so you could probably get away with the same 3% margin of error. 0 and 103 would probably be good values and that matches with post linked to in the answer. | |
| Sep 1, 2017 at 15:54 | comment | added | user3450548 | Sorry to ask again but I tried to apply your solution. If I switch to Chroma and Luma, it happens that 4 settings appears, there's no "Signal Max" and "Signal Min" but "Luma Min", "Luma Max", "Chroma Min" and "Chroma Max". I do believe that I have to set Luma Min to 0% and Luma Max to 103% but I have no idea how to set Chroma Min and Chroma Max to meet the QC requirements. | |

For delivering that much material, consider looking at commercial products like Tektronix Aurora, Interra Baton, or Telestream Vidchecker. One of those is likely to be the software that the broadcaster will be using to QC what you deliver. | |
| Jul 8, 2017 at 9:18 | comment | added | user3450548 | Interesting the consideration for Broadcast Colors, I will avoid using it then. My job this time was to do some post on titles and graphics but as I said I'm not part of the creative process that's why I'm looking for a file based checker or software to limit automatically everything inside the requested values. Is not something that I want to do frame per frame manually.. that's just crazy. I have to conform something like 25 episodes each time of a series, you can understand that what I set inside that parameters must be certain and not a thing that I can experiment each time :\ | |

| Jul 7, 2017 at 20:29 | comment | added | Michael Liebman | The Broadcast Colors effect has been deprecated. It was for NTSC and PAL gamuts and probably won't give you good results with HD. As far as I know for the other Video Limiter settings, there aren't any specific settings to guarantee legal colors. You'll need to experiment based on the look of your project. There are software "meters" out there that are better than using a waveform monitor, but you can use a waveform in parade mode or isolating individual channels to confirm legality. | |
| Jul 7, 2017 at 9:39 | comment | added | user3450548 | Out of curiosity, what Broadcast Colors effect do? Should I use both Video Limiter and Broadcast Colors or just only the Limiter to obtain my purpose ? thanks! | |
| Jul 7, 2017 at 9:37 | comment | added | user3450548 | Thanks for your reply, I'm delivering to an european broadcaster, hence the pal setting I was trying to use in the broadcast colors filter. For what concern the other settings I have idea how to set them. I'm not part of the creative process of making the movie. I had only to join audio and video plus check the correct levels before delivery the final file. I also can't at all use hardware tools, all I can do is software with my workstation. Can you extend your reply trying to match also the other settings like: Reduction Method (i guess i have to use compress all) and Tonal Range Definition ? | |
