Motion Blur in post

[Devin Johnston]

I've never tried to add motion blur after the fact, but the animation I'm working on now is just to massive to justify the additional time it would take to turn it on. I know it's possible to add it in After Effects but I don't have a clue how, can someone walk me through it or point me to a tutorial?

i know in vray you can render a vray_velocity element and then use it in combustion to add motion blur. maybe its possible in AE but im unsure.

Best way to do it that i know is to render to RPF format with the velocity channel stored in the file, then this can be read and added in Combustion. After Effects doesn't have the ability to read RPF format last time i checked, however i believe there are plugins that will allow it to - all for some $$ though.

ReelSmart Motion Blur is probably the next best option and doesn;t require RPF format or a velocity channel, but this again will cost some $$ but at $90 for AE plugin its well worth it.

 

Of course, there is always the cheap and cheerful way... http://uk.youtube.com/watch?v=3jDWnUDwrH4

AE does support RPF

there you go then. bonus!

I'm not familiar with the RPF format, how is it different from a tiff?

here's a great explanation from Gary Davis

RPF is getting very dated though - may be just my own perception but compositing systems have become much more sophisticated over the last 5 years and when combined with the render element features of both MR and Vray, you can get away with a lot and still use a more universal file format than RPF.

 

Oh, and Reelsmart motion blur is the way to go...you'll be very happy with the results
