slow down video according to tempo

Hi,

First, I’m new to Cubase, switching from Logic Pro, so I might not use the correct terminology.
I have a project that includes Audio, MIDI and a Video.

I created Tempo mapping so that my Audio can be played with a metronome.

I turned my Tempo track off (after set definition from tempo).

For practicing purpose, I need to slow down both the audio and the video, but, when slowing down my audio playback (using audio warp), my video speed is not adjusted to the audio speed and is played at the original speed.

In Logic Pro, when i change the Varispeed, the video is automatically adjusted to audio speed.

Thanks
