I have a customer request to do work instruction using Creo Illustrate to create animation if can record voice or sound clip will be good instead of using attached note for video.
When you are done with a video, add it to power point. Create a single slide. Use the voice over feature to add dialogue. Set the video to play automatically and set the audio to start automatically when the show starts and you can at least sync the beginnings.
If you have a marketing person using premeire or premeire elements, you can just slap the two files together in there and skip powerpoint. If they know what they're doing, they can make the video pretty for you too.
Since Illustrate and creoview are the visual wing of MPM Link it would be helpful to offer voice over for videos made in these formats, but also limiting since you can't be sure the user has speakers, or can hear them (machinery) or speak your language of choice.
