It sounds like there could be several issues. A few things to consider – 1) Is the caption file the correct format? 2) Which captioning field is the encoder set to place the caption data? 3) Did they run the video back through a TV set with a decoder to see the captions?
In the future, you could use our company to create a caption file that goes right into your editing system. There is no need for an encoder and there is no generation loss. Feel free to give me a call and I’ll help you understand the different options. We have a full studio with several encoders and multiple format decks so we’ve seen most issues and had to resolve them.
