Actually, I found some info that clarified this a bit.
1.778:1 is the same as standard anamorphic aspect, or 16:9. Havn’t heard the “1.778 aspect” in a conversation in a long time (if ever).
Well, hopefully this may help someone else! I fell a bit, er, embarassed to have bothered you all now!
For the SD footage, Ill just need to place it in a 16:9 comp and place it into the custom 846×486 conform comp. The fields issue, I’m hoping will not be an issue and the footage was acquired with prog-scan. I’m a bit too far down the production chain for THAT to be the mistake it probably will be…
Still, is there a way to output that 96 ppi from within AE?
Thanks!
