Odd NeatVideo defect

Flame Flame Questions
1

I just had an odd problem.

Timeline color. Everything has worked flawlessly as usual. I added an OFX TLFX with Nearvideo for some noise reduction.

Works fine in timeline, and render plays back good in mediahub after export amd on Frame IO. But the file has vertical stripes (half the pixels skipped) in every other player including Premiere.

I take the OFX out, problem goes away.

I add Neat as a BFX node, everything works fine.

Any reason why Neat wouldn’t work as TLFX but is fine as BFX?

This is on 2025, Linux.

Perhaps you need to bump it down to 16bit with a color management timeline fx after?

Good theory. Will test in the morning.

Admittedly I only use neat in batch, but I always add a colour mgmt node directly after the neat OFX node to reduce it from 32 to 16bit.

Likewise. That’s the one odd thing about Neat. Just didn’t cross my mind when in the timeline. And there was only an Image node on it at that point, so using BFX was a couple of extra clicks.

@cnoellert for the win. That solved it.

Though in TL-FX that ColourMgmt node takes a tad more to setup. Almost easier to do BFX at that point. But at least good to know the answer.

Was a bug in the software. Devs were able to reproduce and is in queue for fix.

Was a combination of 16f project and using a Viewing LUT during export (ACES).

@allklier Did foreground vs background export make a difference for you? We have been getting a similar-ish issue, but it only seems to happen with fg export.

Let me add $0.02, We ahve found some artifacts in heavily neated images. These show up as very subtle squares in the image. These so far only show up when you enable gpu+cpu. If you go gpu only then the sqaures go away.

When the devs investigated the background render seemed to make a difference, I never tested it myself though.

Happened to me to the other day on one clip. It was a very difficult clip to start with.
