[Gimp-user] Creating a 16:9 anamorphic image in Gimp

[Jean-Michel Pouré]

Dear Friends,

Hello, this is my post on Gimp user mailing list.

I have been using Gimp for several years, without the need to post a
help message. Why ? Probably because Gimp is so EASY to learn. 

Never say never, here is my first question related to video:

I would like to creata PAL 16:9 anamorphic title in Gimp. What
resolution and settings should I choose? My display is an LCD monitor. I
did not find how to set up PAL 16:9 anamorphic resolution in Gimp.

Any idea?

Kind regards,
Jean-Michel

 I just always create a 1024x576 image and then scale to 720x576 when I
 export for video. 

Sounds good. But Kdenlive will probably soon support XCF files directly.
What if I open and have to export. I would prefer an automatic solution.

 You can create a 720x576 image and set the X and Y resolutions to 9
 and
 16 and then disable dot for dot in the view menu. However GIMP only
 transforms the view, so that round brushes for example will look like
 they are squashed, since they are drawn on the 5:4 image.

Okay. Thanks.

My idea was:
* PAL resolution is 520x576: 1.25 ratio
* 4:3 resolution: 1.33 ratio
* 16:9 resolution: 1.78 ratio

In Gimp, I create a 16:9 PAL image, with the following custom settings:
X = 520 pixels
Y = 576 x 1.25 / 1.78 =  404 pixels

X dpi = 72 dpi
Y dpi = 72 x 1.78 / 1.25 = 102 dpi

It works quite well for large text, but not for small images, 
which are very slightly distored in Kdenlive.

Any suitable alternative settings?

Kind regards,
Jean-Michel
