Pixel Aspect Ratio Translation - maybe a bug?

[Animark]

Hello,

I want to animate a project for a D1 PAL Output (720x576, Pixel Aspect Ratio (PAR) usually = 1,0940). I dont want to draw in such a low resolution and decided to multiplicate 2 times the dimensions of the D1 PAL to a project size of 1440 x 1152 and a PAR of 1,0940. That's the theory.

Starting with a D1 PAL Project in TVPaint gives me a preset of a PAR of 1,067. ???
Ok, however, why not using a PAR of 1,067. So I made a new project: 1440 x 1152 and a PAR of 1,067.

My goal is to get a D1 Pal Movie in the end. To be sure with the workflow I tested to convert and to export the project to D1 Pal resolutions. I found out, that TVPaint translated the PAR between the different steps from 0,937 to 1,067. I never got a result I expected.

Now I am totally confused. I documented my workflow steps on the following picture. Maybe there is a kind of a bug in TVPaint, in the presets or in my workflow. Maybe we can find it out.
For the moment I also would be very thankful if someone could give me good project settings for my project described in the first sentence here.

Thanks from Animark

There is obviously a bug in the display of the project properties...
It displays the inverse of the PAR : 0.937 = 1/1.067 ...

I think it is more than a bug in the display. There must be a malfunction during the steps of converting that changes the projects Picture Aspect Ratio. Have a look at step 4).

I'd just produce with square pixels in whatever dimensions, and only in the last step convert to any non-square pixel ratio. Full (square) PAL was 768 x 576, if I double this I get 1536 x 1152, a comfortable size to draw.

Yes, that is exactly what I decided to use this morning. .
