Videos keep being cut off

[Valerie Langlois]

Hi everyone,

I've been playing around with E-Prime 3 for the past couple of weeks, and everything looks great except that I've noticed some of my longer videos are cut off a bit at the end. The video is of a person speaking, and you can tell it is cut off because the audio is cut off. Since the video file itself (.mp4) plays fine, it leads me to believe that there may be something going on with E-Prime.

Here are a couple things I did to try to solve the problem:

I created a new E-Prime project, and added only a MovieDisplay. But even when only one video plays, it's still getting cut off.

Next, I played around with the settings. I want the video to terminate after it's done playing, therefore duration is set to infinite and End Movie Action is set to Terminate. Everything else is at default.

 

When setting the duration to 6000ms (the video itself is about less than 6 seconds) and End Movie Action to none, the video is still cut off, and afterwards a still image of the video is shown.  

So I'm not sure what's going on here. Perhaps there is a sync issue between the video and the audio (e.g. the video finishes but the audio does not). Does anyone have any solutions to this or what settings I should change? 

Thanks!

How many movies do you have in your List? Does it always cut off at the
same place in the List? How far does the movie get before it cuts off?

There is only one movie in this procedure, and it always gets cut off in the same place. 

The movie gets pretty far in. I would like to say that the last half a second is cut off. In the movie, the speaker is supposed to say "Ana wants to borrow a comic book". But instead, "book" is cut off, and the movie terminates after "comic".

In the original E-Prime experiment, there are 48 other movies as well in the list. Every other movie plays fine. And it doesn't matter if I randomize the list, or play it in sequential order, this movie is always cut off.

OK. I am most interested in the results when running several movies
from a List, because there is one problem that can occur under special
circumstances for the last movie in a List, no matter what movie that
is. I gather from your description that when you play other movies in a
List they all play OK, but you have problems playing that one movie
file, no matter where it occurs in the List (beginning, middle, or end
of List). Do I have that correct?

If so, that rules out one problem that I had in mind. Unfortunately,
that would have been the easy problem to fix. So now I fall back to
suspecting a codec problem with that one file. Around here, each and
every time we have had oddball problems with movie files in E-Prime, it
was a problem with codecs. This has been discussed at length in other
threads on the Group. Remember, .mp4 indicates only the container
format, *not* the underlying codec. Also, just because a movie file
plays in Windows does not mean it should work with E-Prime, because
E-Prime has to perform with extra stringent timing requirements and so
uses its own playback mechanism. Please use the terms "codec" or
"codecs" to search for other threads in this Group that discuss this.
