Anamorphic plates/pixel aspect ratio


Recommended Posts

Heya!

I'm curious if supporting non-square pixel aspect ratios is planned. I come across that issue quite often when working with footage shot on anamorphic lenses - with different pixel aspect ratios of 1.6:1, 1.8:1 or 2:1. It would be great to have a way of loading & displaying those in a desqueezed way, without destroying the metadata when saving them out again for further use in compositing applications.

Any insights on that?

PS: I'm not looking for a workaround like transforming the image manually etc. - I'd love to have a native way of dealing with that :)

With Anamorphic lenses the pixels remain square, the image is squished*. You need to physically stretch the pixels so they are wider and then Rasterize the result.

* Actual real life technical science word. [Really, I am telling the truth. emoticon]

I have never mastered color management, period, so I cannot help with that.

Yes. I know that. What I'm asking is that it would be nice to be able to open exr files with a baked in aspect ratio correctly (displayed unsqueezed in Affinity) and re-saving them without stretching them myself and therefore causing problems or requiring additional steps in the pipeline.

Really depends on what the "pipeline" is. You may not need to stretch the image horizontally if it is simply going to be returned to somewhere that requires a squished image.

This is a valid feature request, there were older questions in the past.

currently as of V2.2, there is no direct support for PAR (pixel aspect ratio)

My posts focus on technical aspects and leave out most of social grease like „maybe“, „in my opinion“, „I might be wrong“ etc. just add copy/paste all these softeners from this signature to make reading more comfortable for you. Otherwise I’m a fine person which respects you and everyone and wants to be respected.

Sorry to revive that old topic, but is there any plannning in this regard? The lack of support for pixel aspect ratios makes AP pretty useless for VFX work on anamorphic shows, as much as I love it for 1:1 PAR work :(

I'm requesting this too. Without PAR Its very hard to do old school pixel art with 2:1 wide pixels for an example. I would happily buy Affinity suite and jump ship from Adobe but right now I can't and this is one of the reasons.

Correct, but in that case it will display squeezed, and FX which are applied which work with distances and angles and the like will be calculated based on the squeezed image rather than the desqueezed image.

I believe the request is to work on it with the data as-is, but displayed and operated on with the non-square ratio accounted for, as it would be in a video editor.
