I have a number of videos from a GoPro and a snorkeling dive which I have strung together using VP 23 and then rendered to burn to a Blu-Ray disc which I will build in DVDA Pro 5.2. But a premature look at the footage makes me think the videos are a bit fast, I want to slow it down for the underwater shots. Now, I know of a quick and easy way to slow down each video in VP and that is to click on a video, choose Properties and change the Playback rate to ie 0.5 and repeat it for all the video shots. When that is done I render the file for DVDA. But this results in a shortened video, not what I want.

The second way that I know is to use a Video FX on the video ie Slow Motion and set it to Fine, 0.5 speed and Adjust Event Length. This will maintain the video length but the audio only covers half the video. I can extend the audio track but it seems to duplicate the audio that only covered the first half, if that makes any sense... I guess if it is only bubbles and me breathing that can be heard it does not matter.

So how do I maintain the original video length and the audio to cover the whole video?
