Finding Size of an Individual "Page" of eLearning...

Apr 28, 2011

Hi,

I have a potential client who have following specifications:

Network speed of 96kbps
Pentium 4 2.6GHz or 3.0 GHz Processor
512MB RAM + 40GB Hard Disks
Internet Explorer 6 +  Microsoft MediaPlayer 9
Flash Player 8

We need to make everything as small as possible, (huge compression on graphics etc.).

How can we find out how big each "page" of a published course is?

What can we do to ensure EVERYTHING is as small as possible?

Any ideas on tips/tricks would be useful - how compllex can I be with my build, given this specification?

Thanks

Bruce

Hi Bruce,

You can view the size of each slide by going into the data > swf folder.  I would recommend combining as many of the "common elements" from each slide into the master slide.  This will vastly reduce the overall size of your presentation.  Also, you'll want to keep the audio bitrate as low as possible.  

Here's a basic article that I wrote about published quality:

Thanks Brian.

I am going to run some "tests" and alternative scenarios.

I guess my question should be that if AP09 only ever "passes down", (excuse incorrect technical term) 2 pages at a time, and you view/hear 1, how big is the page "experience", i.e. the slidesize + audio etc.

In terms of audio bitrate, I record at 41000 mono, save as .wav, and let AP09 "do its thing" when compiling. Should I be doing somethig different to "...keep the audio bitrate as low as possible"? I still do not understand these things - sorry.

Thanks Brian,

I get that, however I am just trying to ensure I understand at what point I do this.

Is it at the recording stage, or once I have pulled the .wav files into AP09, is there something else, recommended that I can/need to do?

Am getting  there, but just trying to ensure I have got everything correct.

Hi,

How can I find out the sizes of individual pages of information that get passed down to screens in an Articulate course?

If I bring the picture into Articulate, and then publish without setting anything, does Articulate then compress the picture again?

I have a specific limitation that I need to work to, but I want to ensure that I am using the highest resolution pictures that I can for the customer.

Many thanks

Hi Bruce,

In the data / swf folder, you should see an individual slide for each SWF.  For example, you'll see slide1.swf, slide2.swf, and so on and so forth.

When you bring a picture into PowerPoint, we don't do anything with the image until you publish it.  When you publish it, we take your Quality settings, look at the image, and then process the entire slide to X quality.

Is that the information you're looking for?

Thanks Brian,

Are the sizes of the bgd and tb .swf files, (I assume background and do not know what tb are!) taken into account as well?

The 6 x bg slides seem to represent the 6 x used Master Slides, the "slide" files seem to represent images of the slides (minus quizzes and interactions), and the "tb" files seem to be pictures of every one of the slides.

I have the ability to go upto about 400k per screen "page", and I am trying to work out axactly what I can and cannot have here. There's no audio, and few.

I am sure there is a simple question I should be asking here - problem is I do not know what I do not know......

Hi Bruce,

Yes, the bdg files are the master slides and the tb files are the thumbnails that load in the outline.  As you can see, there's a huge advantage to putting as many elements as possible into the master slides.  If all of your slides use 1 master slide, then the master slide only needs to be loaded into memory once.  So, the performance across multiple slides is enhanced because the browser doesn't have to reload that file.
