Thank you Simon!
Regarding the size of my media: I should keep it 1024px X 576px to keep the 19:6 proportion, right?
I did try what you recomend for the comp settings before but what got me confused was the horizontal squashing of the image.
I am still a bit confused because the “PAL D1/DV Widescreen” preset gives me a comp size of 720px X 576px and the “lock aspect ratio” button says it will lock it with 5:4 aspect ratio, while the PIXEL ASPECT RATIO is set by default to “D1/DV PAL Widescreen” with a Frame Aspect Ratio of 16:9.
Is this correct? Well I hope so. Gonna try it.
Thanks again,
Zé Luís
