  • Resolve adds black bars when importing media

    Posted by Allard Depallerd on October 23, 2017 at 3:22 pm

    hi Guys,

    im using Resolve to convert my FS7 footage tot DNxHR, so it’s easier to work with in Premiere.
    But when I import my source files in the media page.. it puts black bars on top and bottom of the clip, in stead of just showing the clip as is. And when i create a timeline from my FS7 source footage, it also puts black bars on the sides. So something is going wrong when importing, and when making a timelime..

    Can anyone tell me what im doing wrong (aspect ratio maybe?)

    This is what it looks like in the timeline..

    What is the resolution of your source media? What’s the resolution of your exported DNxHR files?

    The source material is 4096×2160 pixels
    The exported DNxHR file is 4096×2160 pixels

    so they’re the same. So the timeline sequence seems to have the right resolution, but it just adds the black bars within that resolution …
    And like i said before…as soon as i import the media..it already adds the black bars on top/bottom. And it doenst seem to cut off the footage anywhere… so that’s why im thinking its a problem with the aspect ratio..

    Are you using the free version of Resolve?

    Yes I am… is that the problem?

    The free version is limited to 3840×2160 output. Even if you use the “use source resolution” from the deliver page the file can be the same size but the image inside the file is limited to UHD output.

    Ah that makes totally sense.. the source is 4k so when it make the footage fit in a UHD resolution.. you would get black bars on top/bottom.

    Damn, kinda obvious…

    follow up question.. if i want to convert my FS7 footage to DNxHR.. (lossy/lossless)..which one would i need to choose?
    I was thinking DNxHR HQX… but that makes my files 3 times bigger..so im thinking that might be overkill and I need a lesser codec.. but I dont want to loose quality..

    please advise.

    I would use one with similar bitrate and chroma subsampling for the footage you’ve shot. Also better formats take more space, that’s just the way it is.

    These are the ones i can choose from for my 4K footage

    Avid DNxHR 444 4096 x 2160 4:4:4 10 60 3730
    Avid DNxHR HQX 4096 x 2160 4:2:2 10 60 1866
    Avid DNxHR HQ 4096 x 2160 4:2:2 8 60 1866
    Avid DNxHR 444 4096 x 2160 4:4:4 10 24 1492
    Avid DNxHR HQX 4096 x 2160 4:2:2 10 24 746
    Avid DNxHR HQ 4096 x 2160 4:2:2 8 24 746\

    My footage is 4:2:2, 10bit,, 490mbps and 50FPS

    So the only one that ticks all my source footage’s boxes.. is the
    Avid DNxHR HQX 4096 x 2160 4:2:2 10 60 1866

    right?

    If you have Premiere Pro, why don’t you create your proxies in Media Encoder? Just curious.

    Fair question…

    But I have tried that, but ive been getting nothing but errors in media encoder. I have tried numerous settings, but its just really flaky and its giving me error after error.

    And for some reason. .. the Resolve encoder just works perfect for me..
