video in compound stimuli

[jarvis24]

Antonella,

I replied to this one last week, I'm not sure why it never showed up. I actually did make changes in that file--but they were to your stimulus folder rather than your input file. I changed the stimuli to gif images that were listed as movies, e.g.,

_dinosaur.gif (250x50)
_turtle.gif (250x50)
_mouse.gif (250x50)

That was because I found that DirectRT was more open to displaying other videos while another video was playing than it was to displaying images. Just so happens that DRT will allow you to present images as if they were videos using the standard video syntax.

I was able to replicate the delay you are talking about--quite annoying. Try this:
Go into the Windows Media Player (e.g., by double clicking on your movie file). Then go to:

Tools > Options > Performance > Advanced

And uncheck the option: called "Use Video Mixing Renderer"

By doing this, I was able to reduce the flicker to about 16ms on this particular test machine.


With regard to the blurriness, what is the native resolution of your laptop? Try matching that in the Options of the style file I included in the attached sample.
