After Efx / RedGiant DeNosie III - White flash frame render crap

[Jim Fink]

So, I am getting a random frame of white with jaggy edges, on rendered output from AfterEfx 2018.
Using Red Giant DeNoise III.

The source is a 720p ProRes QT and I am using DeNoise III to clean up grain. I have many 10 minute clips, and before I publish an hours worth of media, I have to 4x speed go through every dang master to look for these errant flash frames, and cut out single frames to be replaced by previous frame. Often at least one per hour, sometimes many more than that.

Really spooky if I had to do broadcast long form quickly from Adobe.
This is what used to be an unheard of form of QC.

Has anyone had similar issues with AE 2018 or RedGiant DeNoise III.

Attached is one frame, and then the flash frame that follows it. Almost looks like an Alpha Ch. Screw up. But, it's rendering as a flat ProRes 720p movie. Source is also 720p. I do have Red Giant DeNoise III Cranked up pretty high.

Thanks for any info. on what may be at play here.
Jim

Hi Jim,

Are the 3 Pips embedded in the original videos or are you comping those in AE?

If they are embedded I’m guessing the noise in the black differs from the noise in the PIPs and maybe causing this issue.

Not sure though.

If you are comping in AE, make sure to use the Denoise effect on the full frame video in a PreComp.

Hope this helps.

I don't have Red Giant Denoise but I've never seen AE do anything like
that on its own, so I'm guessing it's the fault of the plugin. The fact
that the white seems to be in 32px tiles seems suspect.

I dunno if that plug is GPU accelerated but maybe try turning it off, or
turning off GPU in After Effects (under Project Settings although I
don't remember AE2018 specifically) to and see if it makes a difference.

Either way I'd take it up with Red Giant and see what they have to say.

Ok, thanks Bob & Peter, this makes sense.

The comp's are pre built in Premiere, so all I am doing in AE is the
DeNoise on a flat pre-built ProRes.

So, yes, I guess Red Giant is perhaps he suspect, as suggested.
And the render type. I have many issues with crashing from CUDA, or
Software only renders and probably also care of my GTX 980 card in an
older Mac.
