MediaLab, Inquisit and Video Issues in Windows 7

What parameter values are you using? i.e., what does your Parameters field look like?

(d220, l.65,t.4) in this case.

I don't believe you can apply a duration parameter to a background video--only to the item as a whole in the primary Parameters field. I do notice that the percentage values do not look accurate on the backvideo in terms of how it's placed. Pixel values seem to work better (e.g, t200,l200) but even those are being affected proportionally by the height and width of the screen. I'll get on this.

Hi Blair,

I know what you mean about the d parameter applying to the trial as a whole.

But, if a video stimulus is being displayed when a trial is ended via the d parameter it causes the crash. (be it presented as a movie trial, or as a background video in another trial type).

I'm using v2010.2.19 on my machine here and I can't get it to crash--even if using a duration parameter on a movie item. Are you using v2010.2.19? Also, with respect to the Inquisit issue above--I'm glad you found (and reported!) a workaround but I was wondering if you were calling it from an .exp file or a .que file. Just curious.

Hi Blair, since switching to v2010.2.19 it works, even if using the duration parameter.

In terms of pulling up an inquisit file, I think we tried through both, but may not have tried from an .exp file.

Glad you found a work-around for running your Inquisit sessions. I just thought of this though if you want to try--can you run your Inquisit session from a batch file (including parameters and all)? If so, you could enter the name of the batch file in the filename of an Executable item.

Very happy to hear all the other issues have been resolved with the latest (2010.2.19) version of MediaLab.
