Hi,

I'm quite new with INQUISIT ad, have problems with a stimulus that is presented on screen and needs to remain on screen during presentation of a .gif-video.

Here's how I do it:

<text STIM> 
/ numitems = 1
/ items = "STIMULUSNAME"
/ fontstyle = ("Arial Black", 18pt, false)
/ txbgcolor = (0,0,0)
/ txcolor = (255,255,255)
/ erase = false
</text>

<picture up_pic> 
/ numitems = 1
/ items = ("up.bmp")
/ position = (50%, 70%)
/ erase=false
</picture>

<video up>
/ items = ("up.gif")
/ position = (50%, 70%)
</video>

<trial up> 
/ pretrialpause = 100
/ validkeys = (200)
/ correctresponse = (200)
/ stimulustimes = [0=up_pic;500=STIM]
/ branch = [trial.up_B1]
/ beginresponsetime = 500
</trial>

<trial up_B1> 
/ stimulustimes = [0=up]
/ posttrialpause = 100
/ responseinterrupt = trial
/ recorddata = false
/ timeout = 1000
</trial>

Problem is: stimulus is erased as soon as video begins.

Of course I can change stimulusframes so that the stimulus is presented again:
/ stimulustimes = [0=up,STIM]
but then I have a flicker problem.
Is there any solution for this?
