Presentations needs faster than 1 second timing

[Guest]

I need to present images for less than 1 second. Specifically, I need to
present images for a fast as 50 milliseconds. I have tried creating mpg or
avi files with this timing then importing them into a presentation, but that
does not work well, as PP tends to change the speed of the movies. This is
very important to my presentations.

Not without getting into some VBA programing and even then I doubt the PPT
rendering engine can work that fast. Especially if you are going to show
them one after the other.

Interesting Paradox,

Let's see, the human eye 'refreshes its central vision about 10 times a
second and you want PowerPoint to display an image for half that length of
time. To get to the speed you are trying to achieve, I suspect you will
need to go with Video (PAL or NTSC) to get even close to this using
increments of 33 or 40 milliseconds. Keep in mind that videos can keep
these speeds because their images are completely pre-rendered and just
shown(streamed), while PowerPoint renders in semi-real-time.

Just as a note, my personal thoughts are that using subliminal messages on
uninformed people is immoral at best and illegal at worst.

Tell us what you are trying to achieve and we may be able to offer
additional ideas.

Ah yes! I am not trying to do subliminal messages. I am a psychology
professor and I am trying to set up a demonstration of iconic memory based on
George Sperling's classic 1960 research in which the participants viewed a
3x4 array of letters for 50 msecs then were asked to write down the letters
in the correct positions. This would be a demonstration of very early visual
information processing (the iconic memory or visual sensory store). I want
my demonstration to be something that any teacher can use in a classroom
setting. You know, free access to knowledge and all of that.

Several years ago there was a presentation package by the name of Astound.
It actually let me present objects for as short as 50 msecs. Unfortunately,
it is no longer supported and the old package does not work with the XP
operating system. I really wish Microsoft or Corel would buy the original
code for Astound and incorporate that rapid timing feature. It was the main
reason I used that package rather than PP or WPP. (Hint to corporate
decision makers!) It also had the capability of embedding video and
compressing the final presentation into a stand-alone .exe file. It was
absolutely fantastic!!

So if I understand correctly, you don't need to show a whole series of images. It
would be sufficient to have one slide on screen, flash another momentarily and then
move on to the next w/in 1/20 sec or so?

It's not at all obvious but you can ask PPT for transition times in tenths of a second
(you have to type the number into the text box manually rather than using the scroll
gadget). Whether it can keep up with the request will depend on the complexity of the
slides and on whether or not you've shown them once during that session (ie, so that
the images are pre-cached).

The one thing I wouldn't count on is accurate timing though. If precision timing is
important, PPT's not the tool.

Thank you Steve! That may be very helpful for some of my demonstrations.
However for the ones involving iconic memory and for those using backward
masking I will need faster timing -- closer to 50 milliseconds. But like I
said, this should help greatly for some of the other demonstrations. Much
appreciated.

Glad to have been able to help. But help me in return, I think my math's gone south.
50msec = 50/1000 sec = 5/100 = 1/20 ... no?

Your math is correct.

All but the last mental step. Yup, I see where I doofussed. Thanks!

PowerPoint lets me present slides at 0.1 seconds, which
