Hey everyone! In this video we show how to use vector blur in Blender 3d in order to composite your renders with more control. We also explain what vector blur is and show how it often differs from the standard motion blur checkbox inside of Blender. Enjoy and let us know what visual effects you want to learn next on the channel.

Hi, nice tutorial! It shows how vector blur works really well. Great example. There are a couple of mistakes in your composite, though. First, Blender renders are associated (premultiplied), so activating the convert premul checkbox in the alpha over node in this case is wrong, as it's applying a multiplication by alpha again, producing a dark fringe around your foreground objects. The other mistake is doing color grading on associated alpha (the curves you apply in the last step). If you're going to color correct the foreground before an alpha over, you must "pre-divide" it first. Place an Alpha Convert node before the CC nodes, from multiplied to straight. If you do that (predividing the alpha before the color correction) then you have to re-multiply it after the CC. In that case (only in that case) the "convert to premul" checkbox would be ok, as it's going to premultiply the foreground you divided earlier. But if you're not going to pre-divide your FG and it comes from a blender render, then it's already premultiplied.

the curve option is probably to correct problems in case of rotations movements

[@oskbarrero]

Is better to see how the curved option works in an object that describe a curve motion: this option affects the interpolation between frames and the effect is pretty good

This is fantastic information and I appreciate you sharing it. But the music is a bit loud.

Hi RunsinTunson, Thanks for the input and kind words. Will keep that in mind for future uploads! Greetings from Los Angeles.
