After Effects Playout … but how?
Hi there
just encountered a little problem i could not find any answer in google. Even though we have been using AE for year, we never had to do something like that 😉 Strange but true.
We are doing some After Effects animations for a customer in 1024×576 square pix, which were ment to be played out as Quick Time Files. Now the customer comes and asks us to do a Playout on Hard Disk Recorder (Doremi) which will only understand PAL SDI 720×576. He wants it to be played out in Letterbox. So i bought Decklink Studio card for one of our machines.
From my understanding, i should just render out the files in one of the Blackmagic codec and do the Playout of these with Blackmagic Deck Control.
Here are some questions:
Which difference does the 8bit vs the 10bit codec make, if all that is pure Animation? Does that have something to do with Sound? The project is 16bit color.
If i render out my animations from After Effects, which resolution should i choose? 1024×576 square pix does not seem to be a resolution the Decklink Software will understand. Does it make more sense to do a nested comp which is PAL 768×576 and put the 1024×576 in that one? Or would upscaling to 1280×720 make more sense to render that out?
Is it better to let the Decklink card do the conversion from HD 16:9 to Letterbox or would it be more clever to already do that in After Effects?
Hope someone can shed some light on this totally new subject. Thanks for any hints.

I mostly work in 1024×576 comps in AE which I then pre-comp and scale 75% horizontally in a 720×576 comp and render that out for playout in Final Cut Pro. I also use that pre-comp for monitoring on a CRT set to display 16:9

OK, so you have your animations in widescreen square pixel.
Your client wants the animation in 4:3 PAL, letterboxed 16×9.
Firstly, I would discuss the options with your client. If you want to output natively from the BM, render your stream to an uncompressed 720×576 AVI, with a DV PAL Widecreen pixel aspect ratio. THis is called anamorphic 16:9.
You can play this out through your BM card. Keep this as a master.
For the letterboxing, I’d do it in after Effects, into a 720×576 DV PAL pixel aspect ratio AVI.
Good luck.
