Slideshow timing

[Joel Nelson]

I am trying to create a PowerPoint presentation of 134 slides at 5 seconds
each. Supposedly that should take 11 minutes and 10 seconds. Instead,
it takes between 15 minutes and 15 minutes 30 seconds. It seems part of
the delay is caused by the computer delaying to open the embedded images.
Is there a way to ensure the slides are displayed for only the set amount of
time and not consistently go over?

 

[Joel Nelson]

I found that the problem is between slides there is a 1-2 second delay
because the computer loads the next picture and it hangs while the picture
is loading. Is there any way to make the pictures be already loaded so the
computer doesn't hang (interrupting the background music and transitions)?

Hi Joel,

What is the size and resolution of the images. Images saved at 72dpi take a
lot less time to render than ones saved at 1200 dpi.

I'd experiment with a graphic editor and do the same presentation with
images at 72 dpi and I bet it will fly right.

They were scanned using VueScan in Archive mode (top quality). I would
guess they're between 200 and 500 dpi. I'll try reducing the size. Does
it matter if the images are embedded or linked? Thank you for the reply!

Forget DPI; you want images in PPT to be sized to match the computer's display
settings. That is, if you're showing the pres at 1024 x 768, then that's the
size you want a full-frame image to be, or perhaps just a wee bit larger.

DPI by itself is non-information. Dots per Inch ... w/o both Dots AND Inches, ya
got bupkess. ;-) Is it a 1" original? 600 dpi is way too low. Or is it a 10"
original? 600dpi is WAY over the top. Knowing only 600dpi, you don't know
which.

Also, try running through your presentation once, before you show it for real.
PowerPoint stores the full image you hand it, so it's got to resample it to
whatever size it'll actually show it at. It caches the resampled image, so the
resampled version's ready for use the next time around. Playing through the pres
once forces it to cache images and should make playback less jerky.

I can't imagine that linking images will make it any faster; if anything,
infinitesimally slower, since PPT would have to check the date/time on the image
file before displaying it. And it may or may not cache linked images; I don't
know.

Joel,

Do you have slide transitions either between each slide or with the pictures themselves. As that would add to the time
it takes to display your pictures.

I went back through and reduced each photo to about 90 KB in size. That
makes it faster overall. I'm still not sure if linking the photos was the
best idea or if I should go back through once more and embed each picture.
(Any suggestions?) The transitions are between each slide (random
transition).

 

[TAJ Simmons]

The transitions are between each slide (random transition).
Not good IMHO. There are one or two transitions that are really slow.

A quick way of assigning a few good transitions is to view "slide sorter" > zoom out really small so you have about 6
columns, then select each column and assign the same transition to each column. e.g. Wipe right (boring but safe)
