Erase Video Stimuli

I've read the "How To" on how to erase stimuli, but this doesn't seem to be working to erase a video. The last frame of the video remains on the screen, and the blank shape does not overwrite the image. Any help is appreciated!

Here's the code:


***video is 1.5 seconds long
<video attention>
/ items = ("attention.wmv")
</video>

<shape screen>
/ size = (100%, 100%)
/ color = blue
</shape>

<trial A>
/ stimulustimes = [300 = attention; 3000 = screen]
/ trialduration = 6300
</trial>

Yes. The best option is to use separate <trial> elements. One to only display the video, followed by another one to do whatever you need to do afterwards (display other stimuli, collect a response, etc.). Hope this helps.
