I got an issue understanding the right workflow of how creating output for TV. My broadcast company is working on D1/DV PAL ( 720x756 frame size / 25 frames for frame rate / 1.0940 pixel ratio / 4:3)
If I work on a comp from After effects using the preset D1/DV Pal with 1.0940 pixel ratio, when it previews of TV all pixels are wider ( i am doing an animation for a square and the square looks like a rectangle ).
The last workflow in the company ( which I think is quite slow) , they did this :
1 - Working in a 1024x576 with Square Pixels ( 1.00)
2 - Bring the former comp in another comp called RENDER THIS on 720x576 with Square pixels too and scale down the comp from step 1
3 - Render the videos and stretch in post using the preset PAL D1/DV Widescreen ( 720 x576 / Lock Aspect Ratio to 5:4 ( 1.25))
4 - Import in Premiere in a Pal D1/DV and export to Tape.
Because I want to work using Adobe Dynamic links, I want to avoid any useless render, and besides, it takes a lot of time.
You should be able to use the PAL preset Adobe has set up in After Effects.In the workflow you described you start in step 1. with a wide screen SD PAL format (although Adobe uses 1050x576 instead of 1024x576) with square par then in step 2. you mention scaling down the comp in a 720x576 square par- if that is the case you are squeezing the widescreen frame in a 4:3 frame and then in step 3. you are stretching it again...?! it's a weird workflow. Then the station format you mentioned in the beginning is 4:3... So do you need a widescreen or a 4:3 final product?
If you do all your work in AE using the PAL preset for 4:3 you should get exactly what you need.
For correct preview in AE click the Toggle Pixel Aspect Ratio Correction button at the bottom of the Composition panel.

thanks a lot, well I am still confused about the reply the IT dept is giving me. They say our format is 4:3 Anamorphic which has a behavoir of 16:9 , kind of like Widescreen ( they broadcast for widescreen and 4:3 at the same time , he said). This does not make too much sense to me. I am trying to get a reply from another guy and seeing what this is all about.
One thing I know for sure, is the final output in Premiere is the presets for D1/DV Pal which means 720x576 and 1.09 pixel ratio.
What i did was working in AE with a PAl D1/Dv preset with 1.09 pixel ratio, and toggling the pixel ratio correction button to preview how should be in the monitor.
Importing in Premiere as Dynamic Links, sometimes I need to interpret the footage coming from AE to Square pixel again in order to look a circle as a circle and not as a oval.
i am not sure if this makes any sense, because I am still struggling to understand what is going on.
I will confirm you exactly what the others engineers say.
I have heard of tv stations that broadcast a signal that uses a widescreen and another that crops the widescreen to a 4:3. In those situations I provided a PAL SD Widescreen par file.
Anyway, whatever the format you should be able to work with the same preset in an Adobe workflow using Dynamic Link.
