How do I slowmotion video

I tried to make a video playing speed control with "set playback time" video but this is not the right way because the plugin crash.

I try :

system every 0.1sec set playback time to Videoplayback time+0.1 sec

Change the 0.1 sec to other value make I thought I will control the speed of the video.

It 's working with 1sec or 0.8 sec but I guess i'ts not made for that ^^.

an idea to do the video control speed in the right way ?

Pick what event you want to trigger it and then for the action choose System >>> set time scale to whatever speed you want.

thx for the answer but I already use that with other objetcs and it's not working with video ...

any ideas?
