Trying to export anamorphic 1440x1080

Hi everyone - quite new to this and dealing with a quite annoying issue.

I'm making some changes to a source mp4 which is in 1440x1080 anamorphic format. All okay: I've set the editor settings to match, done what I need to, it looks great in the Viewer. But when I export, I don't have the 'HD anamorphic (1.33)' option that shows up in the editor, or equivalent. So the video gets letterboxed/stretched/squashed etc - depending what combination of other things I try - when it exports to mp4.

I gather from a bit of reading around that it'd be better not to work in anamorphic, and instead convert the source video when I import it. Good to know for future - but unfortunately this source clip has text in it, which similarly gets stretched/thrown off screen/etc if I do that.

Suggestions very much appreciated!

    @TheBenNorris is 1.33 Pixel Aspect Ratio on export a Pro Only thing, or does there need to be a feature request?

    @wfjp most of your footage is on the Editor Timeline not comp shots?

    @Triem23 you don't export the footage at 1.33. The viewer is automatically adjusting the PAR to render correctly (so it appears 1:1), but when you export it will actually be 4:3. I could be wrong on this, but this has come up before and is how I remember it working.

    Edit: this is correct if I had actually read the question correctly, my bad. Triem's response is probably the most helpful here.

    @TheBenNorris you are correct, but it seems like Hitfilm isn't setting the proper flag for a media player to know to stretch the output.

    @wfjp OK 1920x1080 footage has square pixels. 1440x1080 is supposed to fill the same area as 1920x1080, but with a wider pixel.

    The "elegant" solution is an encoding flag that tell a media player to stretch in real time. Hitfilm doesn't seem to be setting it. A media player will have manual controls to correct for aspect ratio, but that depends on the player.

    Another solution is to render with a 1.33 pixel aspect ratio. This would be more for Blu-ray burning. Looks like Express doesn't have a 1.33 PAR Export.

    A third possible solution is to manually stretch the footage. This is the old school method. You'd create a typical 1920x1080 1.0 Pixel Aspect Ratio Timeline then go into clip Properties, unlink the chain icon for Scale and set horizontal scale to 133.333%. It Hitfilm you can do this to one clip, use box select to select the other clips, then right click and "Paste Attributes" to paste the Scale to every clip.

    Ah, seems I misread the original post before my morning coffee. I'll look into the limitations on Express/Pro when it comes to aspect ratios, as it's not something that has come up before. Deleted my original comment since it gave the answer for a different question.

    Edit: @Triem23 Pro doesn't have a 1.33 export ratio either, I'm not going crazy after all.
