Are Premiere’s waveform monitors useless?
… and I mean that in a precise sense.
Why do I think this? The IRE levels are mapped to the full 0-255 range 0 being 0 IRE and 255 being 100 IRE. That’s fine for web and all but when multiple broadcast standards seem to agree that 16-235 is the range, it makes it less than intuitive to figure out that most deliverables are really 6.8 to 92 IRE on the scope.
Just venting…

Isn’t 16-235 the YUV version of RGB 0-255?
Not totally clear on this…

Well the thing is on the scope 0 and 100 map to 0 and 255. Final Cut Pro is actually a bit more useful in this respect as their scope’s 0-100 maps to 16-235.

Premiere is really based specifically on all media so 0-255 gives you a good range. I’d rather see all that than only being able to see 16-235. I can still see 16-235 in a 0-255 range obviously, but I can’t see 0-16 and 235-255 when limited to a 16-235 scale. Media is being produced for a ton of different delivery formats and outlets so seeing the full scale I believe gives you an advantage. You can still see what you are delivering to TV while also being able to see the values for web, film, etc.

Well granted, the scopes are useful for the 0-255 range, but when most deliverables have to conform to 16-235, I’m surprised they don’t at least put in a feature to switch ranges. I put in a feature request for it though.

Switching between the two would be nice. Also, I guess you could also just add the broadcast filter on it to limit the range. They did add a whole bunch of new features to CS6 so maybe this might be one of them. It’s awesome that they’re listening though.

CS6?
Paul are you from the future? 🙂

I’d like an engineer to chime in, but I believe 16-235 is SMPTE digital range; 0-255 is RGB colorspace, which seems like where Premeire is working. So the ‘scopes are accurate within Premeire. For output, depending on format, you may need 0-255 to be remapped to 16-235. Avid codecs for one will do this. And conversely, bringing in SMPTE digital requires remapping to 0-255.
