Caption encoded file used in a sequence sent to Media Encoder, Encoder present a status warning that
"offline media is detected and will be encoded with the offline media graphic"
When I create the same file that is not caption encoded and replace the encoded one with it in the sequence, the warning status goes away in Encoder.
