White line flickering on the edge

I changed the sequence settings from 1920 X 1080 format to a square 1080 X1080 format. The reason is I wanted to post the video on instagram.

This created a problem: a white flickering line across the right hand corner of the program monitor on certain clips. This line does also appear in the exported video.

- If I change my sequence setting back to 1920 X 1080 this problem disappear.

- In my time line, I have added adjustment layers above all clips. On the adjustment layers I have added the Lumetri Color fx for color correction.

- Flickering appears only when these adjustment layers are enabled. However, some clips do not get any flickering, even when adjustment layer is enabled.

- If I apply the Lumetri Color fx to the video clip instead, and disable the adjustment layer, the flickering goes away.

- However, if I then replace video clip with after effects compostion (I want to add some moving text fx to my video) the flickering comes back.

- I have tried resizing the clip to 300% to ensure the clip fills up the whole program monitor.

- on my time line I have MPEG:s from a DJI Phantom 4 (23,976 fps), a Canon xa10 (25 fps) and a GoPro Hero 3 (25 fps)

- the white line appear on all three kinds of footage, but not on all clips in the timeline. To me it seems random which clips have the whiteflcikering line and which have not.

- i use a MSI GS VR 7RF Stealth PRO Laptop.

- I have restarted the computer several times.

It´s a bug in the Lumetri color and should be fixed but probably not in CC2018.

For me, resetting the Blacks and the Whites in the Lumetri filter fixed the issue. Or, turn off CUDA acceleration.

I had the same problem using adobe cc 2019 (version 14.0.0.0). resetting lumetri color or even deleting thi fx didn't make any difference. neither did the change from "hardware acceleration" to "software only" i noticed however, that the problem occured solely where two or several clipc were stacked above each other. i ended up deleting all the unnecessary clips when the project was finished. that worked an took away those ugly white flickering bar...

I know this is an old thread but I'm having this issue whenever I try and render vertical videos for social media platforms. It's not just white glitches though, I'm getting multi-coloured ones. Seems to be just on the right hand side, only a couple of pixels in width but all the way down, and only appears on some clips. I've tried rendering using the CPU instead of CUDA and it didn't make any difference.

If it's just on the very edge, try increasing scale to 101% or so and crop.

same problem here, only when Blacks and Whites are reset in the adjustment layer the problem disappears.
So we now cannot use blacks and Whites edits anymore?
Anyone?

Are you using the adjustment layer over multiple clips?

You can move black/white via the Luma sliders in the color wheels tab also ...

Thanks for this thread, Ran into this bug today and was scratching my head. Was making a vertical video at 1080-1920 and encountered this bug. Sure enough disabling basic color correction tab fixes issues

Any update on this??? I'm having the same issue. Wondering if it has been updated in the latest Premiere?

Not addressed in the last .01 patch. Adobe is aware of this issue and we are looking forward to releasing a fix for this soon.

Dead Adobe, the issue has become a pain while rendering videos for many of us. Please solve this at the earliest.

I had the flickering line in one of my projects and it was only on 1080x1080 sequence. My project included a clip in 16x9 aspect ratio (3840x2160) which was also rendered in 1x1 aspect ratio (1080x1080). The workaround I found to get rid of the flickering line is to render the 16x9 sequence and in the render settings I set 1080 by 1080 resolution and source scaling set to scale to fill.

Edit: I also used an adjustment layer on top of the footage to make color correction with Lumetri

Has anyone found a fix for this or is it a bug that Adobe need to patch in an update?

I've just spent nearly two hours chatting to Adobe and they were utterly useless and couldn't work out what the issue is. I just gave up in the end.

Thanks! That seems to have worked! Astounding that customer support couldn’t give me that answer in nearly 2 hours of chatting with them!

It’s annoying that the issue affects the whites and blacks controls as they’re used very frequently. It it looks like this issue has been around a while so hopefully they’re close to a fix.

If anyone can share a small project that reproduces this issue, please send me a PM. I'd love to reproduce it over here at Adobe.

If you can create a small test project with a piece of media that would be perfect - otherwise I can try on my side with just a project file. I'm sure there are some useful clues even with an offline project.

Also, please lmk what GPU's are being used when this occurs.

Thanks!

Hi Guys,
Had a similar issue: Ugly white brackets at the right Border during playback in AE and completely ignored Adjustment Layer when rendered.
I basically just made a new Comp, and rebuilt the Lumetri color settings on a new adjustment layer step by step and rendered it again, this time without problems.To me it seems, Lumetri doesn't like to be copied...
Hope that helps...

i solved this issue by color grading (adding lumetri color) directly to the footage. don't add this on adjustment layer.

Same problem here...

Thanks for the workarounds so far...

Ok so putting to "Mercury Playback Engine Software Only" worked.

BUT rendering goes so much slower...

I found this happens somewhere in the Lumetri's BASIC CORRECTION zone. So I did right click/reset each one of the properties there until I found one that made disappear the white line. In my case it was the Tone/Blacks property.
