Hey y'all, I'm trying to desqueeze some footage using media encoder and all the necessary elements seem to be set to the correct settings, but when it exports I have a 1.333 aspect ratio frame with a 16:9 squeezed video in the center. Basically, the "Stretch to Fill" option under the "Source Scaling" section doesn't seem to be doing its job, despite the preview being the correct aspect ratio.
here's a before & after of the issue: https://imgur.com/fLkv3WH

as you can see the preview shows the video in the correct aspect ratio, so I'm not sure what I'm doing wrong for it to export incorrectly. Would appreciate any help y'all can give! thanks!
Macbook Pro (16 inch, 2019)
processor 2.4 ghz 8-core intel core i9
amd radeon pro 5600m 8gb
intel uhd graphics 630 1536mb
adobe media encoder v15.4.1
acquisition: shot on a samsung galaxy s10+ using the app Utracorder
just bumping this in hopes that someone who can help sees it. Cannot figure this one out for the life of me.
The Preview shows the correct aspect ratio because that's what Pixel Aspect Ratio (PAR) Correction does. Also, Stretch to Fill isn't meant for changing a clip's PAR value.
To conform a 1.33 PAR clip to 1.0 PAR during transcoding, you'll need to import it into After Effects or Premeire Pro, add it to a Composition or Sequence that uses the desired PAR value (in this case 1.0) at the desired square pixel frame size and then queue that up to Media Encoder. For example, import a 1080p 1.33 clip (native 1440-by-1080, display 1920-by-1080) into After Effects, create a Comp from it, change the Composition settings from 1440-by-1080 1.33 PAR to 1920-by-1080 1.0 PAR, then add to Adobe Media Encoder Queue. AE will do the PAR correction so that the 1.33 source footage fills the 1.0 Comp.
All that said, your screen shots shows that your source is 1.0 PAR and that your output is 1.33 PAR. Did you intend to introduce a squeeze? If the source is 1.0, you usually don't need to make PAR changes as it's more common to go from 1.33 to 1.0 rather than 1.0 to 1.33.
dang I was hoping to avoid having to use premiere at all, is there really no way to desqueeze anamorphic footage with media encoder?
And to answer your question, the footage was shot 1.0 PAR on my phone using an anamorphic adapter, so to view it in the proper aspect ratio you have to set the PAR to 1.33. So the video file is 1.0, but the "correct" PAR is 1.33, if that makes sense.
