Motion blur sample exported as individual frames

Hello… I am experimenting a weird issue… I have a sequence that i’m trying to render… the previous one worked out perfectly, but now, it seems that if I use just the image sequence (.png) and the deferred rendering, my image sequence are made of all the motion blur sample… (so by default there are 8 samples, so I have 8 frames created, then fr 2, ex. this creates a very studering animation… (unusable)…

I don’t kow what I did to make this happen… besides adding some bloom and lens flare on some cams + adding ambiant occlusion and global illumination…

so, right now, the only way to bypass this. is to add the anti-alisaing option in the render menu, set the sample to 8, and cancell the AA…

thx…

Marc.
