Adobe Presenter Embedded swf appears choppy or twitchy

Problem:

When embedding a swf animation into adobe presenter, the final movie apears twitchy or 'stuttering'. This occurs because the "Control using presentation playbar" option is selected, and Presenter is doing odd playback control on your swf.

Basically, to keep the slide time synched with your swf time, it is either jumping ahead or backwards to keep them together, not ideal at all!

Solution:

I did not find this solution to work for me, but it might for you, it's pretty low effort to try and if it works great!

2. My Solution:

First I cut all of my main timeline and chucked it into a movieclip which then got thrown on frame 1 layer 1 of the main stage (make sure the main timeline is the same length as the new movieclip timeline), we'll name the new movieclip "allAnimations".

Now, the playback bar for presenter won't have access to this movieclip, so the stuttering effect is gone, but what if the user is jumping back and forward, how do we sync this animation up with the main timeline?

Here's the magic (Actionscript 2.0):

allAnimations.onEnterFrame = function()
{
if(this._currentFrame - this._parent._currentframe > 150)
allAnimations.gotoAndPlay(this._parent._currentframe)
else if(this._parent._currentframe - this._currentFrame > 150)
allAnimations.gotoAndPlay(this._parent._currentframe)
}

Basically if the animation's timeline differs from the main timeline by more than 5 seconds then sync them up!

This is a hack, i'm positive there is an unfound better solution, but for now this may work for you, if so enjoy!

Articulate Quizmaker Fill in the Blank Correct Response Not Appearing Bug and Solution

Ran into a situation with an test built in Articulate Quizmaker not showing some correct responses during "review".

The question with the problem was a fill in the blank type, and it's fill in the blank field was just about the size of one or two characters.

Well, apparently you have to be very careful when using small boxes in these questions, because if it's too small the correct answers just will not show up during a users review of the quiz.

I would recommend going with a four or 5 letter sized box, should do the trick until this is patched up one day ;)

Boring Long Technical Description (BLTD) to Follow:

For flash geeks, what I can only assume occurs is that Quizmaker determines the width of it's dynamically created correct answer text fields based on the initial input box, combine this with a kinda unstable text renderer in flash and you get the disappearing text....There's probably a width = width - 10 somewhere that needs to be removed ;)
