Render issues: white lines

[Pirube]

Hi all,

The preface

I'm having a serious problem while exporting from After Effects 15 (cc18). Both on my 2013 Mac Pro on High Sierra as on my MacBook Pro (2017). Both have AMD graphics cards. When I render from the render queue, from any project, I get white lines on some frames. A single pixel, horizontal and/or vertical. You can see it on the desk on the right. Is anyone else experiencing this, because support says they haven't seen this before. When I Google or search these forums, I can't seem to find any info on it either.

I run rubberhose 2 and motion 2 plug-ins on both setups, but they worked fine in cc17. I recently upgraded the mac Pro to High Sierra, because Adobe told me too. I think I was still on Yosemite before and couldn't install cc18 without upgrading.

The problem

As said, when I render from the render queue, from any project, I get white lines on some frames. A single pixel, horizontal and/or vertical.

I contacted Adobe, because this pretty much destroys my workflow: I have to check every frame of the rendered file and fix these frames manually in Photoshop and Premiere:

Support

They told me it's an Apple problem, caused by the drivers of Open CL / Metal in High Sierra. This is weird, because it's the same under Sierra with cc17 and it didn't occur in cc17 under Sierra.

Their solution: render via Media Encoder, using the software renderer. At first this seemed to work. I actually did one render that was fine. The next day, it simply didn't work anymore.

This must be some kind of bug. I'm experiencing it under both Sierra and High Sierra with CC18 (AE15).

The "solution"

To perform the ultimate test. I rendered the same project with cc17 ont the MBpro and it has no white lines whatsoever. In my logic it would be safe to assume that it is an Adobe problem and is'nt driver related after all.

I hope the problems don't occur anymore after I roll back to cc17 on both machines. It's a shame though and I feel let down. This has cost me many hours of troubleshooting and testing in a week with tight deadlines. That's of course a lot of frustration that shouldn't have happened.

I hope this discussion temporarily helps other people having troubles with white horizontal and verticla one pixel lines in their After Effects CC 2018 renders.

If you have any more info or maybe fixes please do reach out!

Thanks,

Pieter

Hi Pieter,

Not that's it helpful to you now, but maybe to others: don't update/upgrade in the middle of a project, especially when tight deadlines are involved. When a workflow is OK, don't change it.

Carefully plan updates between projects and take your time to test them out. I usually take an image of my entire system drive and when things don't work out I roll back in no time.

Vrolijk kerstfeest,

Hi Wim,

That's of course always a good thing to do. Problem was that I didn't notice the problem early on. Some projects don't have the white line render problem at all.

What I just can't believe is that I'm the only one experiencing this. On two different computers. With different Os' and that cc17 appears to be unaffected.

I have also experienced this issue. In a project that was not displaying the white line previously. I am not finished with editing yet, but this will be a big problem if it is not fixed by the time that rendering comes around. I see that our problem has not been solved. Can we hear any sort of response from an Adobe representative?

hi, i have this on all ntense renders? Adobe says my mac is damaged. did you find any other solutions.

[Pirube]

Well, it's not a real fix within cc 2018, but downloading and installing cc 2017 (AE 14) solves the lines for me. I have tested on both Macs now and they come out OK. It's most certainly better than painting every line frame in PS.

Of course it shouldn't be happening in CC18, but at least I can work without having to worry about those lines in cc17.

Cheers,

I have a 1px white line appearing for two frames of an animation. The frames in question are a static image, slowly scaling.

Windows 10, GTX770, I73930K, 64GB

Disabling CUDA (Mercury software only in Project Settings) seems to 'fix' the issue. Not sure if the equivalent Mac settings will help, or not. Good luck.

**Adobe - is this a known bug, is it going to be fixed soon?

[Pirube · Accepted solution]

Hi mrbenjamino​, as far as I know, CUDA is nvidia related, both my macs have ATI cards. So I can't use your fix. 🙂

The only solution I managed to figure out, is saving as a cc17 file and working from there.

Pieter,

I would take the MacPro to a service center and have them test your GPUs. The white lines indicate that they may have heat damage and giving you poor rendering results when using the GPU. Others in the video editing realm have seen this anomaly more frequently. The 2013 Mac Pro has problems dissipating heat, it seems.

Let us know what they say.

Thanks,
Kevin

recently upgraded premiere  i saw  this for  the  first time today in a file i rendered occasional white horizontal lines, I  a am slightly terrified.  hardware damage ?Is this a definite diagnosis

[mrbenjaminjo]

Of course it isn't! It's an Adobe fob off.
