Preserve Aspect Ratio of content while output Aspect ratio is fixed

In other words: By default, don’t distort the content!
Let’s say I have defined my output to be a standard 16:9 aspect ratio. Whatever I put in should have this aspect radio in the end. Currently, any content of a different aspect ratio would be stretched to fit the frame. I would like to see letterboxes or pillarboxes instead.

Today, I could apply a filter to zoom the image accordingly, but that’s not what I am aiming for. I’m good with additional black, but I don’t want to change my actual content.

I noticed i.e., and Amazon Elemental Media Convert offers this behavior already.


Thank you for your insight and the good explanation of your use case. This is very helpful. Currently we don’t offer pillar and/or letterboxing and have no timeline for support yet. We will make sure to consider your interest in further roadmap planning and keep you updated on our progress.
