Is there any way in Premiere Pro or Media Encoder to encode whatever today's digital equivalent is of a SAP channel (Secondary Audio Program)? We're getting a lot of requests to do Spanish-language equivalents of our English-language videos, and the solution so far has been entire second productions in Spanish, which of course are cumbersome and slow our output. What I'd rather do, to streamline the process, is just record a Spanish-language voice-over and dub that in on an encoded track, so viewers can simply choose which language to listen to at home with their remote. I don't know if or how that type of encoding can be done in any Adobe products. I heard basically since the switchover to digital TV, that SAP capability (at least in the traditional sense) is gone. Can someone please help me on this?
