Thanks - but I'm not using any transition. All I've done is to place a scrolling page (screen recording) into a monitor.. I've done this plenty of times, and never had this issue. I've tried multiple screen recordings in different resolutions, and they all get stripes. I've even tried other stock videos with green screen monitors, but all with same result..  ¯\_(ツ)_/¯

Unfortunately your link doesn't offer any solution..

Came here to say I'm having the exact same issue. I noticed it on a project that I had been working on when all of the clips I had corner pinned had strange vertical lines. Messing with the dimensions more revealed the moire effect. I rolled back Premiere from 24.1 to 24.0.3 and it fixed the issue. Here's my documentation of the issue (yes I was a dummy and posted it to the wrong subreddit): https://www.reddit.com/r/AfterEffects/s/a5wMT4ZUv0

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Yes, I had the same. No issue in 24.0 only showed up for me in 24.1

Hey, I just did some playing around and found a work-a-round in v24.1 if one prefers not to go back a version or to beta.

I put the invert effect before and after the corner pin effect, lines are gone. Not elegant, yet my day can progress... 🙂

Can confirm that a downgrade vom 24.1 to 24.0.3 fixes the problem with the corner pin effect. (Win11, RX6600, AMD processor)

Apparently when I have a clip with the Corner Pin Effect applied I get striation patterns appearing on my image. I never had this problem with previous versios of Premiere. Is there a way to circumvent this? I hope this gets fixed soon.

Hey,
I have a problem with Premiere Pro showing lines-artifacts when using Corner Pin in a way that program
Task:

  • General idea is to a add video to a mockup of smartphone.
  • It requires cropping of a video which is recorded in 1920x1080;
  • It requires placing cropped video on a mockup;

My way of dealing with it:

  1. Adding cropping effect and cropping it + creating mask on opacity to round the corners.
    2. Using rotation, position and scale to roughly place video in the right spot.
  2. Creating nest (*)
    3.  Adding corner pin effect and dragging points so it would fit the smartphone perfectly.
    (*) nest is applied to get corners of pin effect closer to the area that actually must be visible

 

Problem  - although it is the easiest way to to this it creates visual artifacts (lines) when perspective is pushed beyond what program thinks is acceptable, even though the perspective looks natural.
I had no such problems with other mockups (usually, artifacts appeared only when perspective was weird) but this one seems problematic for PP.

 

My solution (terrible one) - avoid corner pin and using Basic 3D & Transform. Way less accurate and way more time consuming.

I guess, I'm doing something wrong but it must be something obvious since I see no topics related to this issue.

 

I'm attaching video with visible artifacts + file of PP (with video clip and mockup) where one clip is created using corner pin and second one using transform and basic 3d.

just a quick thought.  Are you using any source material that's interlaced?
