Question

AlphaFromTo Effect in Captivate 5

Hi all,

Yet another problem I'm encountering.

I have a slide in a presentation whereby the Slide starts with an image.

After 3 seconds this image starts to fade using the AlphaFromTo effect, fading from 100% to 20% Alpha.

Another image then zooms in from behind this image using the FadedZoomIn effect.

The slide is then paused until the learner clicks the "Next" box that appears after a set time.

The issue I'm getting is that the faded image is snapping back to 100% Alpha prior to the slide transition.

This is only happening for the briefest period of time (0.1sec?) but looks atrocious within the project.

Is there something that I'm doing wrong?

I've tried changing timings on the slide but cannot get it to stop the "flash" at the end.

Any ideas?

August 2015 - still an issue.

I remember from the early Flash days that alpha settings of 100 and 0 were problems. I'm going to try and replace all my fade effects with 99 and 1 to see if that helps the flash after a fade-out.

Well, this did help in some instances but not all. Then, I discovered the 'timing panel' from the window menu (cap8). I'd thought the ability to apply fades had been removed but I am so glad to find it here. Apparently there has also been a lot of discussion about the timing panel being missing, but I think that has to do with the 'basic' versus 'expert' workspace. Still, wish the alphas would work as commanded.

I see what you are saying Rod, however the idea was that you could see the image beneath as it faded out.

I've left it as one zooms out as the other zooms in. Looks ok.

Not as good as I would have liked, but it will suffice.

Thanks again.

I would advise repositioning your image layers so that the second image actually zooms in above the first one. Then while the second image is on top and covering the second image, you can get rid of the first one without anyone knowing. Then you won't have it appear at all when the slide transition kicks in.

I've seen similar problems when trying to apply an effect like a drop shadow to an image that remains on screen for several slides. The drop shadow effect can only be applied on each slide separately. So it terminates a split second before the end of the slide and causes a brief flicker. I had to apply the drop shadow ina graphics program outside of Captivate to get it to look seamless.

Such are the limitations of Captivate effects at present.

Thanks for your help Rod,

Annoyingly the image Zooming in is actually a text caption that is obviously transparent and therefore doesn't block out the initial image at all.

I've had to change the AlphaFromTo effect to a FadedZoomOut effect as there was no way to stop the flash of the full image on slide transition.

I'm wondering if this is a bug in the effect.

Speaking of bugs, I found that if you have a rollover text caption with two colours of text in, when you publish the project Captivate merges the two text colours. I had black and vibrant blue text in one caption that became a dull blue on publish.

Just as an interest point.

Cheers again!

Does the text caption that is zooming in have Fade In set as an object transition? If so, and all you really want is for it to zoom in and cover the other image, turn off the Fade in transition and change the initial Alpha on the effect to 100%. If it is zooming in from 0% size to 100% sizem no fade in is really required.
