Avid + Resolve = Tired Pixels
on Nov 8, 2017 at 2:50:18 pm

Working on a feature originally shot on RED DRAGON.
Long story short I am dealing with DNxHD in Resolve (HD) and getting a washed tired output to BluRay.
To be honest it looks better on the BluRay using an old Panasonic 720p plasma but still looks dim for my taste.
Waiting on an Eizo CG247X but for now, stuck with a 10-bit OSEE LCD as ref.
I know this is a loaded question but anything in the waveform I should be looking at?

Where are you building your bluray? How is it interpreting the dnx files would be my first question.
How did you create them in Resolve would be my second question. (Auto, video,data)

Are your blacks "black" in the waveform?
Try outputting a test file of a greyscale ramp. I find that a pretty easy way to see how the blacks and whites are being affected after they leave the box.

Thanks Glenn for the quick response ☺

I'll answer as best I can (not at the studio today).
AAF from Avid so it's reading straight from the Avid MediaFiles folders.
I didn't check the output options but rendered to ProRes 422 and used Adobe Encore for authoring.
The blacks are mostly hitting zero on the waveform but I do recall that most of the meat is between 0 and 700.
I have my Panny set to Standard and did a few tests using Netflix, Apple TV, cable and a different BD disc (theatrical).

With the monitor you are grading on, did you view the bluray to see if it was the same gamma as the original grade. The question is if you are getting a difference and what might be done to fix that.

It also begs the question of how accurate your grade monitor is.

[Michael Gissing] "It also begs the question of how accurate your grade monitor is."

Currently using an OSEE 10bit display.

I was hoping it wasn't but Ill know soon enough.

Still waiting on my Eizo CG247X to drop.

I will be taking the project over to a studio (Flanders) this weekend.

In the interim, I pushed the gamma up to the point that it looks blown up on the GUI.

Looks great on the OSEE but would have to test that theory with a BD burn tonight.

I watched the two versions on a Sony XBR 4K LCD.

The original darker version seemed closer to the tone the movie was shot in.

The brighter one was okay and looked way better than my home Plasma but still a little washed.

This was on a BluRay HD burn.

I know this isn't the most optimum workflow but it's all I got at the moment.

Time to put that Panasonic 720P to rest (2006).

It sounds like you dont really know which monitor is accurate (if any) in the first place which is going to make correct this kinda like chasing your tail.

Did you try bars or a simply black to white ramp to see how they look?

I have to find time for that.

This was a rush job that will need to be revisited once I get all my displays in.

Ive already warned the producers that this was a dumb workflow.

I got a hold of a LG 31MU97 and hooked it up via HDMI.
The OSEE 10bit shows no banding and has similar luminance.
The LG, however, is showing some banding not sure if that's an HDMI cable issue.
Using a 2160p 10bit HEVC gradient test pattern.
