Thank you David - I've got it working following your suggestions.<br>
<br>
Although it's straightforward in principle, a few of the settings are crucial so for the records here's what I did to play video and sound simultaneously (ie overlapping) but with them not starting at the same time (in my case starting the audio after the video has starting):<br>
<br>
- setup a SLIDE with video sub object on it to play your video<br>
- set the duration of the SLIDE to be the time delay you want until your video starts (ie NOT 'infinite')<br>
- set the properties for the Movie object as follows:<br>
- 'End movie action' : Terminate<br>
- 'Stop after' : No [this means the video keeps playing after the slide finishes] (default is yes)<br>
- AFTER the slide, insert a SoundOut object on its own onto the Session Proc
timeline and set this to be the sound commentary you want to accompany
the video<br>
- set the 'Duration' to 'infinite'<br>
-on the general tab, set the 'End Sound Action' to 'None'<br><br>Notes: in this situation, if the audio finishes first, then the video keeps playing to the end but if the video finishes first, then the audio is truncated.<br><br>On Friday, 24 August 2012 14:39:20 UTC+1, McFarlane, David wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">John,
<br>
<br>Um, yes. Starting an audio file with some delay after starting a
<br>video equates to starting playback of the two files
<br>sequentially. You are merely stymied by seeing your video stop when
<br>the sound file starts. My guess is that you do not know about the
<br>Stop After property of MovieDisplay and SlideMovie objects. This is
<br>set to Yes by default. Try setting it to No and then do as I
<br>suggested earlier, and see how that works for you. I cover all this
<br>in my online E-Prime course.

<br>>
<br>>Hope that helps.
