Group: Forum Members Posts: 15, Visits: 40	Hi, I have a big problem right now. My program includes two parts: video display and slider bar display. A series of facial expressions will bedisplayed dynamically as short video clips. Each clip will last two seconds and disappear afterwards. After theclip, an intensity rating in three emotion categories (anger, disgust and fear)will be presented. The format of the video is mov in mac and wmv in windows. The average size of the video is 160kb. The mac-version program can run quite fluently on mac, however, the win-version can not run fluently on win7. The programs are the same except for the format of the video. The problem on win7 is that the start of the video and also the start of the slider bar lose frame. They become black at first and then show the stimuli. Hope the following language will help you to understand my problem better. Hope to get the reply from you soon. Thanks! <video a_d> /items =("f08_a_d.wmv","f22_a_d.wmv","f27_a_d.wmv","m07_a_d.wmv","m28_a_d.wmv","m71_a_d.wmv") /select = noreplace / size = (15%, 100%) /playthrough = true /erase = (255,255,255) </video> <text fixation> /halign = center / items = ("+") / fontstyle = ("arials",40pt) / txbgcolor = (transparent) </text> <trial a_d> / stimulusframes = [0=fixation;500=a_d] / response= noresponse </trial> <surveypage evaluation> /caption = "In welke mate zag je de volgende emoties op de laatste gezichtsuitdrukking die werd getoond in de clip?" /fontstyle = ("arials",20pt) /subcaption = " " /subcaptionfontstyle = ("arials",50pt) /questions = [1-3=noreplace(anger,fear,disgust)] /itemfontstyle = ("arials",15pt) /itemspacing = 5% /showpagenumbers = false /showquestionnumbers = false /finishlabel = ["next"] /nextbuttonposition = (80,85) /navigationbuttonsize = (5,5) </surveypage> <block emotion_practice> / screencolor = (255,255,255) /trials = [1,3,5,7,9,11=noreplace(a_d,d_a,a_f,f_a,d_f,f_d);2,4,6,8,10,12=evaluation] </block>

Neither is reproducible in Inquisit 4.0.5.0 on my Win7 system using your code (which, BTW, has a number of syntax issues you should fix) w/ a bunch of random WMVs I happen to have around. Which makes it likely there's either - something wrong w/ your WMVs and/or - your system's codecs. First, make sure your Inquisit installation is up to date. Second, check whether the issue only happens with (a) your facial expression WMVs or also using (b) other WMVs you have around and (c) other video formats (e.g. any MPG you have available). Please report back w/ the results.

However, it cannot run fluently in my work computer and lab computer, which are also win7. I have tried downloaded the codec and also converted the wmv to avi, mp4. However, it doesn't help at all. If this is the problem of video, why the slider bar also has this problem (flash at the start)? I have already asked many people to help and have spent one day to solve it. However, we have not find a way yet. They thought maybe it is a problem of the computer drive. Hope you could fix it. Thank you so much!

Group: Administrators Posts: 13K, Visits: 108K	> If this is the problem of video, why the slider bar also has this problem (flash at the start)? I don't know and I'm not seeing that problem on my Win7 systems. Taken together with the fact the issues also don't happen on your friend's Win7 box (as you report), suggests that it's something about your office / lab machines. Asking again, because you haven't said anything about it: Have you made sure you are using the same, up-to-date Inquisit version on all machines? Also, I'm confused about the code you posted. The full script in your last reply doesn't match the earlier excerpts. E.g. Then: <video a_d> /items =("f08_a_d.wmv","f22_a_d.wmv","f27_a_d.wmv","m07_a_d.wmv","m28_a_d.wmv","m71_a_d.wmv") /select = noreplace / size = (15%, 100%) /playthrough = true /erase = (255,255,255) </video> Now: <video a_d> /items =("f08_a_d.wmv","f22_a_d.wmv","f27_a_d.wmv","m07_a_d.wmv","m28_a_d.wmv","m71_a_d.wmv") /select = noreplace / size = (15%, 100%) /playthrough = true </video> With that in mind, you'll also want to make sure that you're not running different revisions of your script on the various machines.

It says nothing about the machines' general performance characteristics, their display adapters (graphics cards) or possible driver and codec issues which may be at play here.

Group: Forum Members Posts: 15, Visits: 40	I really doubt the computer of the lab is worse than my friend's computer. And most probably, my colleagues and I use the same version of inquisit (4.0.5.0). Because we belong to the same university. Whatever, I will check it tomorrow. Hope it works. Because I have to run experiments soon and this is a big problem.
