Activity Forums Adobe Premiere Pro Clips come in with the wrong pixel aspect ratio

  • Clips come in with the wrong pixel aspect ratio

    Posted by Luke Mullen on March 18, 2017 at 7:27 pm

    NOTE: I’m aware that this is one of those issues that Premiere will blame on Resolve and vice versa and I’m posting in both forums because I’m not sure where the problem lies.

    I’m having a strange issue bringing in clips created in Resolve. Clips are 4096×2160 Op1A DNxHR444 MXF files. Export settings in Resolve are set to square pixels. When imported into Premiere, it thinks the pixel aspect ratio is 0.937. If I bring the exports back into Resolve it thinks they’re 1.0 like they should be. Anyone have any ideas why this might be?

    I tried MediaInfo but it doesn’t show pixel aspect ratio. Not sure what other programs I can use to check PAR.

    Also, I know I can manually modify them in the Premiere project window to be 1.0, but I’m trying to relink to a sequence, and when I relink in the link media window they came in the way Premiere interprets them which is 0.937

    [Luke Mullen] “When imported into Premiere, it thinks the pixel aspect ratio is 0.937”

    That is correct.

    UHD (3840×2160) has a PAR of 1.0
    4K (4096×2160) has a PAR of 1.9:1

    That’s the aspect ratio. The _pixel_ aspect ratio should be square with both of those. Are you using the free or the Studio version of Resolve?

    Right the frame aspect ratio for UHD 3840×2160 is 1.78:1 and the frame aspect ratio for my clips at 4096×2160 is 1.89:1, but as Tero said, I’m referring to the PIXEL aspect ratio which should be square (1.0 in Premiere).

    Tero, I’m using the full studio version of Resolve.

    Can you try to export that to some other format as a test? Just to check out if it’s just DNxHR that does that.

    ProRes4444 exported from the same Resolve sequence with the same settings comes into Premiere with the proper 1.0 PAR.

    Ah yes, slip of the mind.
