flickering after recording a video with the sequencer

Hi all,
I’m always facing the same problem :

With the camera playing in the editor, my scene is ok (light, effect, AA…)
While recording via the sequencer this very same camera, there is a huge flickering.

Here are 2 videos to show the phenomenon

1- in the editor : https://vimeo.com/336578270

2-when recording with the sequencer : https://vimeo.com/336578161

I really don’t understand why the sequencer give a different result of the editor.

Hope somebody can help me please !!!
