Img Media Source and Movie Render Queue

Hi!
I have a little issue concerning the “img media source” and movie render queue.
When i’m playing the media in the sequencer, no playback problem everything going well.
BUT when i’m using the movie render queue, i have a playback issue with the img media source has a 2 or 3 frames in advance or late, depends of the shot.
I know unreal has issue with the playback of movie files but not with image sequence.
Do you have an idea how to fix it?
Thanks
