Broadcast safe

Hi,

I got this from the client:

Luminance and sub-blacks. Luminance should not exceed +0.7v or 700mv. Sub-blacks should not fall below 0v.

Can someone translate this for me? How does this relate to my waveform scope in Resolve?

Best regards,
Daniel

full range 10 bit (0-1023)

"broadcast safe" 10-bit = (64-940)... or 16-235 in 8 bit

Okay, thanks. This is a spec. I was given AFTER I completed the grade. So, I've been grading using the full range 10 bit (0-1023). Do I need to manually go through each grade and make sure it's between 64-940 on my waveform scope or is it possible to make it broadcast safe on export? Either from Resolve or Premiere Pro.

Hmmm, there are several solutions, some people apply a LUT or use TRACK instead of CLIP correction. The dumb and lazy amongst us sends the finished outputed file thru another application in FCP or AE for one-click legalization.

In my experience the only solution that reliably and accurately works is a good old hardware legalizer. Still no software options that work as well.

Okay, can you give me a link? What sort of hardware legalizer? A scope of some sort? How does it work in practice?

The Harris DL-860 is pretty much THE standard for SDI legalization.

Daniel,

You dont need to regrade. 0-1023 is ok!

When delivering you can use adtoox, adstream or similar file based delivery companies. They have softwares and internal controllers that will make sure your commercial is within legal ranges.

Or, you can go with a hardware legalizer (tape machine)
