I am trying to put together a training video using a recording from a webinar. When I try to add the video to Captivate, I receive an "internal error" message and no video is uploaded. I have used the Adobe Media Encoder to format the video. After using the encoder, the video will load, but there is no volume. I have tried encoding several ways, and even used a custom format which indicated that the audio is included. Is there any way for me to play the video through captivate with the sound from the webinar?
