Offer 1.5 speed option?

[nikolausm82011740]

Hi,

Interesting question by a client.

Can we offer 1.25x or 1.5x replay speed on normal slides (not video)?

Youtube and Netflix have it...

Thanks for any input!

Passive video is not the same as interactive eLearning. Do you create only MP4 output? Or are you talking about interactive HTML5 output?

I am talking about HTML 5 output and not video. So I am aware that it is not easy/impossible. But a client asked and so I am thinking "why not"...

You could create a button and execute JavaScript for the success action.

cp.movie.speed=1.5;

Not sure about 1.25, but 1.5x and 2x can be done with putting this line of js on a button or something:

window.cpAPIInterface.fastForward(); 

Clicking the buttton once increases the playback speed to 1.5x, clicking it again increases it further to 2x. Clicking it a third time returns the speed to normal.

Actually, if you happen to use one of the built-in playbars, you can tick 'Fast Forward' in the Skin Editor, and it will put such a button on the playbar.

The Fast Forward button on the playbar will toggle from 1x to 2x to 4x and back.

You can check this by using the console. Press the fast forward button and then check the value of cpInfoFPS

You'll see that it goes from 30 to 60 to 120

cp.movie.speed=1.25;

Can be used as well. Try setting it in the console. FPS will then bump to 37.5

You could even create some buttons to increment a variable and set the speed to the variable allowing for a much wider range of speeds.

This affects the timeline so the problem comes in when you have things running independent of the timeline as they remain unaffected by the speed changes.

Thanks a lot but I think the client thinks that the "Podcast speed listening" experience can be recreated. It can´t of course...unless we recreate every slide again with sped up audio and jump to that version when the button is clicked! But life´s too short for these kinds of antics.

I can understand to provide fast forward moving for a video, but don't see any use case to have this for interactive slides? Why do you use faster moving in video? To go quicker to a specific part, to jump over parts ???? But that can be done easily in any interactive project without needing to increase the Frames per Seconds (is a system variable).

Note, that if you do this, any slide audio will be muted.
