motion blur output
hi,
i have had a nagging problem and still can’t figure it out. i am on after effects 6.5 and have not been able to output any comp with motion blur. i have selected motion blur on the layers in the comp. and ram preview looks good. no matter what codec i use to output, i do not get the motion blur effect. used to work perfectly on earlier versions of AE. now that i’m outputing to fcp, using either amimation, h.264, dv, or graphic codecs, it does not even attempt to work. it renders, just no motion blur that makes it look good.i am on a mac G-5.
any thoughts? i use after effects a lot, but mostly basic stuff, motion blur is needed though.
cheers,

Best Settings for render settings?
-
yes, it is set for “best setting”s.

double check the best settings, make sure that motion blur is on for checked layers. this shouldn’t be a codec issue…
are you using opengl for previews? i’m kind of grasping here, but i’m looking for differences in preview settings versus render settings.

yes, in the render settings window motion blur is on for checked layers.
quality: best
resolution; full
disk cache; read only
proxy use; use no proxies
effects; current settings
solo switches; current settings
guide layers; all off
frame blending;
on for checked layers
field render;
off
3:2 pulldown; off
frame rate; 29.97i can’t figure this one out and it has been an issue for a couple of years and i usually just give up. i want to solve this issue finally.

years???!!!
well, you’ve probably checked this already, but there is an update for 6.5 available (6.5.1).
have you tried posting in adobe’s ae forum? how about re-installing ae? or, download the beta for cs3 and see if mo-blur works in that version, if it does… upgrade next month.
maybe you could get it to crash… i’m much better at troubleshooting macs that crash, i’ve never heard of motion blur not working.
you didn’t mention it, but i assume opengl is not enabled for renders (in the render settings) or previews (in the preview pref).

open gl is on for fast preview. thanks for your help. i’ve had this issue on a couple macs.

opengl… now we’re getting somewhere.
i’ve seen a strange issue with opengl on a macpro with ae7, where if you apply an opengl accelerated effect on a layer (with opengl enabled) ae crashes, but if you apply it to and adjustment layer it works great. i realize this doesn’t relate to you problem, but it does show that opengl in ae can do strange things.
what g5 (dual, quad? mhz?) and graphics card do you have?
i’ll have to double check, but i believe that opengl acceleration in 6.5 did not support motion blur (as an accelerated feature). and i’m thinking that you may have a graphics card that is opengl 2.0 (which does support accelerated motion blur) but that may be creating some sort of issue with ae6.5.
whether this is the case or not, i would try disabling opengl for previews in the preferences. then check a ram preview for motion blur. if motion blur works without opengl on then the final render should also work (they will be using the same software render engine with opengl disabled).
if the ram preview has no motion blur with opengl disabled, re-inable it and set the render settings to use opengl for final renders (i’m pretty sure 6.5 has a check box in the render settings). see if the render has motion blur.

well i tried your suggstions. i even moved the project to my new macbook and it still doesn’t render with motion blur. i guess it’s just me. i used to get wonderful motion blurs when i was on a mac 9500 and after effects 4.5. time to upgrade everything? my macbook is pretty new though.
thanks for trying to solve my issue, i appreciate it.

i’m not too surprised by ae6.5 having some issues with a macbook… there are many issues that i’ve run into with 7 on an intel mac (quad macpro).
i’m kind of surprised with such an odd issue on a powerpc g5. which g5 do you have? and what osx version are you running? selecting about this mac will give you the number of processors, speed and osx version; more info will give you the graphics card and bus type (agp, pcie…).
i suppose as a work around you can save the ram previews, you’ll just be limited by how much preview you can fit into your ram.
