This IS the Avid L2: [Avid-L2] Re: Anyone made a GXF (SMPTE RDD 14-2007) file?

This is for a Promo. Even the client is surprised he is being asked to caption a promo. That's never happened in his career.

Fortunately they accept avid mxf media in SD and HD. Very smart of them IMHO. I'm very interested to know how you insert an AFD and Captioning 708 files along with the other stuff. I was under the impression you always have to also have 608 caption files too so the downconverts and older monitors can run the old standard of captioning. Does this mean the 708 carries the older 608 captions inside itself along with the new 708 data? I'm jealous of all the fun your getting to have. ;-(
