Animation slides skip content in published flash

Question

Dear helpers and experts,
I may be new to Captivate, but have worked with all its
predecessors...
My simple demonstration consists of 6 slides:
a text slide;
an animation slide built from an avi file (123 sec);
a text slide;
an animation slide built from an avi file (23 sec);
a text slide;
an animation slide built from an avi file (165 sec)
When previewing all content is shown. Then I publish (export
HTML). The viewed flash skips the end of all animation slides: from
the first only 107 sec are displayed, from the second only 10
seconds, from the third only 110 seconds are displayed.
To be precise on the previw: it is the Play button on the
timeline where everything is played - not "Play this Slide" in the
Preview button - which creates a temporary flash file.
With uncompressed Flash it's the same problem.
What went wrong here?

Answer 1

I have now found the source of my problem:
There is a difference whether I insert via
1) Insert > Slide > Animated Slide - or
2) Insert > Blank Slide; and then in the blank slide:
Insert > Animation
In case 2 I get the dialog "New Animation" where I can set
options. In case 1 this dialog does not show up and with Slide
Properties the desired option can not be set.
The desired option to cure the problem is "Synchronize with
Project".
The Help text concerning this option "Select this option to
synchronize the speed at which the animation file plays with the
Timeline speed. (If you find that the animation file is not playing
smoothly, test with this option selected and cleared to see which
setting gives you better results.)" did not trigger my brain at
first, because when playing the animation (imported avi) in the
TImeline it is displayed correctly with or without this option.
Hence: if the final flash file skips the end of imported
animations (eg avi) and jumps to early to the next slide:
- Import the animation into a blank slide (do not import via
Insert > Slide > Animated Slide)
- Set the option "Synchronize with project" in the "New
Animation" dialog
