RE : PPT to Video
I have resigned to the fact that " optimized " ppts are not recognized by
any converter.
Just want to know " why " in layman terms.

t-4-2
 
Yes, optimized for size.
I used NXPowerLite to reduce the size of my ppts which usually run over 10
MB, and for e-mailing out, I had to reduce them to smaller sizes.
Now I used PresenterSoftPowerVideoMaker ( recommended by one of you ), as
well as the Wondershare, and they both returned with " file does not exist "
or " unable to copy file ".

Additional infos :
After the " optimized " ppt was rejected, I went back to the original
pictures, re-did the ppt exactly as the last one with actual size ( 8.08
MB ), converted it to video using PresenterSoft. It went through fine,
except it ballooned to 33 MB, but at least it got accepted.

PowerPoint 2003 or 2007?

Why do you put space around quotes and parentheses?
 
If you mean MS Office Picture manager, no I have not.
It is because, for reasons unknown to me, when I called up the file which
contained the pictures, they were NOT in arranged order. They were arranged
in manner such as p1, p2, p3, p4 etc in the file, but instead, they showed
up scrambled. I couldn't use them that way. Besides, I have no idea how much
resizing will be sufficient, and I have to resize 128 pictures ? I don't
think so.
Not sure I make sense to you, but that's why I ignore it.

You can try E.M. PowerPoint Video Converter, meet all your needs. It
can quickly converts PowerPoint to video, audio and images, such as
avi, flv, 3gp, swf, mkv, mpeg2 ts, DVD, mp4, mov, mp3...

T42,

There is a built-in image compression tool in PowerPoint that is a bit
hidden and clunky, but works fairly well. Here is the click-path to do the
file compression:

1. Make a copy of your presentation (just in case)
2. select any picture
3. On the Picture Tools Format tab, select Compress Pictures
4. In the small dialog box that opens, select Options
5. Make sure the top two options are checked and the bottom (Email) option
is also selected
6. Click OK out of the options
7. Ensure the "Apply to selected pictures only" option is unchecked
8. Click OK to perform the optimization
9. Save the presentation and compare the filesizes

Note that the images in the optimized presentations will be make "just
detailed enough", so, if you might need to enlarge an image, you will want
to keep the originals for re-insertion.

Thank you. I was wondering why you said " compression " instead of resize.
Still a question :
You said " you might need to enlarge an image ".
I have 128 pictures, and if they are too small, then..........? 128 pictures
?

Tried your built-in compression. Result : from 8.89 MB to 8.03 MB.
Not quite enough. But, yes, it's better. Thank you.

After compression, the picture's resolution has been reduced based on 1) the
size of the image on the slide and 2) the size of the screen. It all gets a
bit complicated, but think of it this way.

Before compression:
Perhaps your projector uses 1024 pixels width. No matter what, you will not
be able to use more pixels than that.
You insert a picture from your camera that is 3000 pixels wide.
You resize your picture so that it is only 1/2 the slide's width
Remember the screen is only 1024 pixels wide, so if the slide fills the
screen, half of that is 512 pixels.

What happens to the other 2500 (3000 - ~512 = 2500) pixels? Easy, when
windows sends them to the 1024 pixel width projector, it rounds them. It
takes the average of every 36 or so pixels and makes a single average pixel.
Remember this is a 2 dimensional grid, so it isn't just 1:6 horizontally,
but also 1:6 vertically, yielding 1:36 (6x6). Of course it is a bit more
complicated, but that is the concept. The picture is shown at the
resolution available.

It gets more confusing, because windows does not just send the picture to
the projector screen, it also sends it to your monitor screen, which may
have a much higher (or lower) resolution. The user may also have the edit
screen zoomed to just about any size. We'll ignore this part for now.

Still with me? I hope so.

Compression:
When you compress a file, it figures out what size you can use. In our
example above, we can only actually display about 1 pixel of every 36, so
the computer averages the pixel and throws out the un-needed stuff. Because
the image is optimized, the computer has saved all of the usable picture
information, and discarded the detail that can not be used. This has two
benefits and one drawback.

Benefits: smaller files size and faster display. Since we have throw away
35/36ths of the picture's size, then PPT file will be smaller. It will also
be "right-sized" so the computer does not have to do any averaging to figure
out what pixels need to be displayed

Drawback: If you decide later to expand the picture from 1/2 screen to full
screen, it will appear blurry. Your picture's pixel resolution was reduced
to 512, but now it covers 1024 pixels (screen width). It will not look
sharp. That is why I recommended holding onto the originals, if you are
likely to need to resize the images.


If I have completely confused you, don't worry, you are not alone.
I could give you illustrations of looking thru a screen door at stretchy
pictures ... lol

How many slides/images?
1 picture per slide. ( picture layout - 1 picture )

How did you insert the images?
Insert > Photo Album

Total # of pictures inserted 126.

I am using 2007 version.

Through PPT 2003, PPT's picture compression doesn't work on photo album
pictures; if you Insert, Picture, From File it does.

In 2007, picture compression works on both types of pictures.

Now I used PresenterSoftPowerVideoMaker ( recommended by one of you ), as
well as the Wondershare, and they both returned with " file does not exist
" or " unable to copy file ".


At least none of us Microsoft PowerPoint MVPs recommended Wondershare's
software, please read this: http://www.pptfaq.com/FAQ00156.htm. Regarding
Presentersoft: I have never used it. I like to use TechSmith Camtasia
Studio. It does not "convert" the presentation, it records what you see on
screen. So if your presentation can be viewed, it can be recorded to video.

Regarding video file size: That depends a lot on video screen size and
framerate. For medium-sized videos (800x600 pixels) at 15 fps, 1 to 2 MB per
minute for WMV video should be considered as normal. MP4 flash might
compress them a bit smaller.

Best regards,
Ute
 
I'm in a no win situation.
I can use PresenterSoft to turn ppt to video, but the size will be too large
to e-mail.
I can compressed the ppt with NXPowerLite, but PresenterSoft won't accept
the ' compressed ' ppt.
Thank you all anyway.
