Legal values
Hi,
I have read a lot on the forum but I need the correct information.
If I click the normally scaled video button, this gives me monitor output that are legalized (64-960). But, this is for me useless as it doesnt apply to the render output.
I need a solution to work within broadcast legal and output legal levels.
My problem is when I do my corrections in Resolve (with normally scaled) applied, it still gives me an full range output. When importing it to Avid, applying a legalizing-filter, its clipped.How to work with this?
I work with everything from RED to F3-log and I need a solution to output legalized material for avid-import.
And one more thing. How do I read the internal scopes when they are set to 1023, its impossible to do the correct corrections if it does not read 64-960 as is legal for broadcast.

A shot from the hip here, which I forgot to mention last night in our conversation on e-mail.
In the Render window, you should have a choice whether to render with normal or full scale. -
Hi,
would you publish the content of your email conversation regarding legal levels here because other people might be interested in your findings as well;-)

I see, that will probably make it happen. I will try, thanks!

Unfortunately there are no “render normal scale” in the render window on my version (8.01).
That option will probly solve everything.But even if this will be integrated in the new version I need to read the scope as legal vaules and not from 0 to 1023.

if you double click on the waveform, you should be able to set the bottom and top values. then you get at least a green line showing you those boundaries…
hope that helps.

Ok, thanks!
But do you guys seriously mean that you work this way, it sounds ok for web delivery, but for broadcast (709) – no.

you can output full range YUV or DPX and be totally done for broadcast , since others system along the line will scale on the SDI like resolve does ,
for example if you render out scaled DPX to a flame system or smoke , flame will scale again on the sdi so it will be double scaled (washed out ) , so there no only 1 way to do it ….

Yup, the video monitoring selection of full-range vs. legal only applies to the video outputs from the card – if you want that transform to appear in your renders, use an output LUT that scales to 64-940 (you can create one in just a minute with the soft clip lot generation tool).
Once you add the LUT you will probably want to switch your monitoring to “full range” to avoid doubling up the effect, but you should get an identical image to your displays. I usually use external scopes, but I imagine that you would see the scaling on the internal scopes.
That’s what I do in this situation, at least, going to Avid or places that request legal values.

The green lines are good for scoping your manually adjusted legal videosignal.
If you want an automatic legalizer, you can use one of the output LUTs from the configuration page. The output LUT will be used for your render. To adjust the range of the singnal to be compressed use a self generated LUT & the softness sliders. This scales your signal more in the hi- & lowlights and lesser in the midrange. -
We had this very discussion here a couple of weeks ago with different answers. For example that Resolve always renders legal when going to a YUV Codec like ProRes. Even without a LUT.
And after applying a 64-940 LUT during Render and going back to FinalCut there where some very washed out blacks and lowered whites.
Could someone from Blackmagic please offer some final answer. There is nothing in the manuals about this topis as far as I know.
Thanks
Ingo
