video files

[David Vinson]

Hi Katie,

It's hard to guess what your problem might be without knowing a little 
more (eg video file size, etc).  In my experience trying to get videos 
of various types to work in E-Prime, most video problems tend to be 
codec problems rather than anything else.

You can also do a simple experiment to test whether size matters - 
create a video that includes only a few frames of your large/problematic 
video, and see whether E-Prime likes it.  If it still doesn't work, this 
should rule out size as a source of your problem.

If it's a codec problem, here's a very quick summary of what PST Support 
suggested to me with a similar problem: download VirtualDub (stable 
32-bit version), compress using ffdshow video codec, encoder type MJPEG, 
save as AVI.
The very latest build of E-Studio (2.0.8.79) has added a Codec Config 
tool, which allows you to render these newly compressed video files 
before using them in an experiment. Seems handy in solving such problems 
although I haven't worked with this in detail yet.


Your problem could also be something completely different - is the 
problem movie file in the experiment directory? (or does it have the 
path correctly designated).

good luck,
David V
