Weird white artifact while rendering Matinee?

Hello. I noticed some weird white artefact on some of my frames while rendering out Matinee. At first I though that it will dissapear while I was working on other things but it didn’t :stuck_out_tongue:

Can someone please help me ? Artefact is visible on middle photo, first one and third one looks good

Photos:

Thanks and Cheers !

Anyone ? Anything ? :stuck_out_tongue:

This occurs on almost every corner and it is pretty visible even if it is only a few frames out of 60 FPS. Can I do something about it ?

I did some experiments and I think that this could be caused by darkness of my images and/or DOF and/or motion blur.

But I do not want to change any of that :stuck_out_tongue:

Can I do something about it ? Anyone got any idea ?

Thanks and Cheers !
