Flash Specifications

I'm contracting a business to create a Flash introduction (approx 15 sec in length) to go at the start of our training. They are requesting some further details around dimensions (e.g. 720 x 540) and also frame rate etc. We use Moodle as our LMS.

Can I ask, so I make sure I'm providing the correct information.

Dimensions = 720 x 540 for standard view and 980 x 560 for no-sidebar view

Question: Which aspect ratio do I choose? Will this depend on which slide view I choose for the slide I'm inserting the flash file onto? Are there any obvious concerns using the 980 x 560 and then changing the view to standard view?

Frame per second = 30 frames per second?

Flash version = Flash player 7 up

File extension = .swf or .flv

Are there any other things that you can foresee that may impact the creation of the Flash intro and also the problems with inserting this intro Articulate.

Any information would be greatly appreciated.

Regards,

Renee

Hello Renee,

in my opinion 720 x 540 is a 4:3 ratio which compromises slide view implications and weight implications (a flash intro should be "light" to start immediately, without having the user to watch a preloader that takes ages....)

I would go for a flv exported at 700Kbps rate (The Moodle scorm player does its job well until you don't push it at a media server level...), but if you like a swf export, a 30fps is the best. Both at version Flash player 7, yes. just go standard for every audience.

hope it helps

Thank you Stefano!!! Brilliant.

I have a further question on video for you.

On another project we have an external completing some video. There are a couple of questions that have come up for the creation of the video.

He has asked a couple of questions and I written the following answers, however codec? and file size? Can you recommend what would be the best options.

Video format: -

Supported file types include the following:

AVI Files: .AVI

Windows Media Files: .WMV, .ASF

QuickTime Files: .MOV, .QT

MPEG Files: .MPG, .MPE, .MPG,  .M1V, .M2V, .M4V, .MP4,

Digital Video Files: .DV

File size (recommended) -?

Video codec required - ?

Ratio required (4:3 or 16:9)  - when converted to .swf or flv format it willat maximum size of 720 x 540 pixels. I believe that 4:3 would be fine as it isnot going to be viewed via a computer screen and not a wide-screen TV

Renee,

file size really depends on the video content, other than its size and length....

Articulate allows great streaming features, but if you want a very good quality video, i.e. at 2000-6000kbps rate, you should need to publish your work to a web server or LMS server exposed over the internet at high bandwidth, and the server itself should push it effortlessly , and users should have fast access to the internet.

So I would suggest, for a very good quality, to tell your external consultant to provide a mov file at 1500kbps, 4:3, 720x540.

Depending on the software they use, they could export directly in FLV using Sorenson or VP6 codec, and that it is good, too.

otherwise you will have to turn it to flash video, using Articulate Video encoder.

Then try to publish your work and see how it is played on a different computer, at a different location, at a medium bandwidth.

If it takes too long to load... then you will have to ask them to lower the bitrate to 1000kbps; if it is still slow and not fluent, 700kbps.

Hope it helps,

Stefano

If you happen to not want to use the full screen for your flash presentation at any time, I created this Excel file to calculate the pixel size of the flash content I need to create. It means that if I want something in flash that doesn't take up the whole slide, all you have to do is set your drawing guides in PowerPoint to the edges of the areas, add the left and right points together to get your width, then add your top and bottom guides together to get your height. Put those into the spreadheet, and it will tell you the pixels for your Flash presentation.

if you're not sure about how to use the drawing guides, just do the following:

  • Right click anywhere on a ppt slide
  • select grids and guides
  • tick Display drawing guides on screen
  • click OK

Some guides will appear on the screen. You can move these by dragging and dropping them, and add new ones by pressing ctrl and dragging and dropping them.

If this is no use whatsoever, then I'm sorry, but it helps me
