How to do video Publishing in captivate 9

Dear MVP's,

I am looking your valuable advice. Actually I created one training project for our employees. related Excel. Beginning of the project I kept 4 normal slides with text with voice (TTS), after that i used CPVC slide (actually I captured excel steps in video mode separately and saved as separate file). Now my problem is not able to publish. If I publish that CPVC slide looks like excel screen shot, only my animations,highlight box, and background music playing. Please advice where is my mistake.
