Aspect Ratio Bug

  • October 4, 2020

Latest upgrade is causing my 4K 4096x2160 25p when placed on a 1440x1080 25fps timeline and reduced to 50% scale to squeeze to 4:3 aspect (including for export). However, if I scale to 51% it holds it's 16:9 aspect.

 

What has changed in the upgrade and how can I remedy this issue?

 

Thanks,

(Premiere Pro 14.4.0 (Build 38) on MacBook Pro Catalina 10.15.7)

This appears to be fixed in 14.7.0 (build 23)

Can anyone else confirm?

      I updated to 14.5.0 today hoping that the problem would be fixed (it wasn't).

      But while checking to see if it worked on a completed project (originally edited with WIN 14.3.2), I found that by adding any video effect to the clip fixed the aspect ratio problem.

      Disappointing it hasn't been rectified. I tried to replicate your effect theory and while it spread to 16:9 as a preview still in the program window when an effect was added, for some effects (gaussian blur as an example) it immediately reverted back to the 4:3 squeeze when playback commenced. And so we wait 😞

      I'm having a very very similar issue. I just started a new video at 1080p. Same settings as two other videos I've done recently. I dropped in a graphic and if I reduce the scale below 50%, the image gets squished because it changes the aspect ratio. I used this same image in my last two videos without any issue a few weeks ago. This is super frustrating as this is a pretty basic thing I'm trying to do here. No updates available yet.

      did you try ann's workaround?

      "I can reproduce: workaround is to set clip to SCALE to framesize"

      That seems to have done it for the png image as well. I guess I'll have to manually select that every time until they fix it. 😕😕

      At least its a solution. Thanks!

        A workaround is a good idea. But just try setting the scale to 50.1 instead of 50.0. The fit appears ok. Even entering 50.0001 works, but it will only display the first decimel, so you can't tell what your setting is.

         

        You could also try rolling back to your previous version. Do you know what version you last had? I have not tested as to which version created the issue.

        Unfortunately, I'm out and about at the moment and don't have my laptop on me. I do tend to keep my creative cloud accountant fairly current, but as part of this latest update I updated the OS as well, and I'm not sure what implications that had on what premiere updates were available to me.

         

        Work around it is for now. I do always worry about line and scaling issues when i'm scaling by uneven multiples, especially decimals, but I guess it'll have to do. 

        Cheers for looking into it for me.

        My tests indicate a change in PR behavior from 2019.1.5 to 2020.4.0.

         

        PR 14.4.0 Create sequence from preset HDV 1080p24 (1440x1080 23.976fps PAR HD Anamorphic 1080 - 1.333)

        Import sample 4K (UHD) sample: 3840x2160 23.976fps PAR square. 

         

        Add video to sequence. When prompted (does not match sequence settings), keep sequence settings. Select clip in sequence. In Effect Controls -> Motion -> Scale, with uniform scale checked, set to 50.0.

        In Program Monitor (set to "fit"), appearance is 4:3.

        Change scale to 51.0.

        In Program Monitor, appearance is 16:9.

         

        PR 13.1.5 Same process. However, both scales (50% and 51%) display as 16:9.

        Hi Stan,

        I think you understand my problem. Your specs are slightly different, I generally work in 25fps, but yes.

        Ideally, I don't want a work around. I generally don't have time for workarounds, and a product such as this used in the manner in which we all use it should notnusffer from such basic deficiencies.

        Do you hve any suggestions as to who to make aware of this?

        Many thanks,

        Stan Jones

        It is probably a bug. Premiere Pro does have scaling isues with Mask, Mattes and simple PIP. Does the problem go away if you enable high quality playback or use software only mode. See if your results are simular to the video below.

        It persists after opting for 'high quality' playback, and as I said this is not just a playback issue. The aspect squeeze remains on export. I should add that the 1440x1080 frame remains 16:9, it's just the clip when scaled to 50% loses it's uniformity and squeezes aspect to 4:3 so the exported clip now has black bars either side of the vision.

         

        This problem has reared it's head after the latest update. I opened a project I fortunately exported 2 days ago and the scaling is completely up-the-creek on much of the timeline (many different size clips, phone vision etc all scaled amd all over the place)

         

        For those with a deeper understanding (greater than mine) here are the rest of the specs

         

        MacBook Pro (15-inch, 2019)

        2.3GHz 8-Core Intel Core i9

        32 GB 2400 HHz DDR4

        Radeon Pro Vega 20 4GB

        Intel UHD Graphics 630 1536 MB

         

        This needs to be fixed now. This is inacceptable. Roll back the update if need be.

        fwiw, 1440x1080 is an anamorphic format which is probably the source of the issues.  Not sure what your level of expertise is so ignore the following if you already know this stuff.  in an anamorphic sequence the individual pixels are rectangular not square.  Make sure that your sequence settings for the pixel dimensions (not the image pixel dimension) is correct.    Generally Premiere does a pretty good job dealing with these issues, but nowadays, delivery formats are usually SQUARE pixels, so you might consider setting your sequence settings to 1920x1080 with square pixels...  yeah, something's proably buggy in the new update, but this is probably where the problem lies.
