I have open gate Alexa footage (4448x3096) ProRes4444 MXFs. Upon import via Media Browser, Premiere Pro (22.4.0) is seeing a resolution of 4480x3096, resulting in vertical black lines on the right and left (presumably 16 pixels wide).
Is this a known bug? Is there something I'm missing?
My Asst. Editor has already passed clips to GFX for tracking and screen replacment with this altered raster size (4480x3096), so I'm afraid I've got a bit of a mess on my hands...
Looking at Arri's Formats and Resolutions Document, I see this must be Premiere Pro looking at Recording File Container Size insteand of Recording File Image Content, resulting in clip padding of 16x on left and right. DaVinci displays the 4448x3096, and this seems like the desired result for an NLE. Is there a reason Premiere Pro has opted instead to display the footage with the clip padding?
