Help with setting up a video file?

[SusieF]

Hi,

I have started to use EPrime 2 and have had a look through the forum
for any help, but I think my paradigm is a bit unusual.

I am setting up video files which play simultaneously in different
areas of the screen. I would like to set each of these videos to
different x and y co-ordinates and to be able to vary those co-
ordinates between trials. I'm not sure if this can be done? Or, where
I could look for information about how to do this?

I have found a labour-intensive way of presenting the videos, using
separate trials, but this involves manually typing each trial out and
replicating the triallist for each trial... Which seems very time
consuming seeing as each trial requires a similar amount of
information, but just slightly different locations for the videos.

Thanks for any help that is provided, I very much appreciate it,

Susie

Hi Susie,

funnywise I posted an answer to someone with about the same question
(yet for only one movie display) on the pst-userforum a few hours
ago... just funny how sometimes everyone seems to be working on
similar things simultaneously.

Anyway: this is what I posted there:

In your triallist create two attributes to hold the x and y values
i.e. "moviex" and "moviey". In line with your example the value of
moviex and moviey in trial 1 (first level assuming sequential
ordering) should be set to 100 and 100 and for the next level to 400
and 400. In your slide object select the movieobject (dragdown menu at
the top) and select it's properties (green tab). In the properties you
can specifiy an x and an y-value for the slideobject. Fill out:
[moviex] and [moviey] to make the slide get it's values from the list.
E-prime will automatically auto-adjust the value to [moviex]:center .
Don't worry about that, it's all fine. If you don't want a specific
movie to appear in a specific position yet rather have the positions
randomized... : stick the moviex and moviey attributes in a separate,
nested and randomized, list.

Now: for your setup you can simply create as many x and y attributes
as you have movieobjects i.e. movie1x movie1y movie2x movie2y etc.
etc.


Best,

Hi liw,

Thank you so much!!!! That is so kind of you to reply - I needed to
know how to do that so I could design the rest of my experiment for my
PhD - thank you very much.
