Motion blur not working on precomped still
Hello!
I’m working on my first project in AE 7.0, and I’m having a problem. Here’s what’s going on:
I assembled lots of stills in Premiere to get the images quickly synched to the audio, and then I imported the Premiere project into AE. Most of the stills are larger than my PAL project (720 x 576), and in Premiere the stills were automatically scaled to fit my 720 x 576 project. So what AE did on import of the Premiere project, was create precomps for each of the stills where the stills are scaled down to fit the 720 x 576 size. The main sequence from Premiere thus became a comp in AE with all stills being in separate precomps. OK, no problem. Now I’m animating the stills in AE, and this particular one I’m animating I wanted to have swing away like a door. I made it a 3D layer, moved the anchor point to one edge, and animated the Y-axis rotation. Simple enough, right? Well, with motion blur enabled both on the layer and the master motion blur switch at the top… no motion blur is applied. I hope I’m overlooking something really simple. I tried creating a test comp with just the precomp in question, and in this testcomp I did get motion blur applied! Does it have anything to do with the fact that it’s part of a larger comp with lots of 2D layers? If anyone has any idea what’s going on here, I sure would appreciate any advice/suggestions.Kind regards,

i just set up a test for this based on the info you’ve provided; and i don’t get any probs with motion blurring my still either precomped or not…
motion blur does chug through the memory, does your machine chug when you apply it; or is it ignoring it completely?
how many layers/precomps do you have?
if you render a still, do you see the motion blur?

Is the still moving quickly enough for motion blur to be apparent ?
You may trying adding more motion blur by adjusting the shutter angle in the advanced tab of the composition settings.

Thanks for your reply:

Do you have the “collapse transformations/continuous rasterization” button checked when you succeed? If I turn off that button, I also do get motion blur, but then I lose the ability to zoom into an image without quality loss, since Premiere scaled all my images (appx. 165 pics) down to fit my PAL working space (some all the way down to appx. 10%). I could of course replace every precomp in my main comp with the raw image, but since I’ve got so many images, and I’ve already spent a few days animating based on their already scaled down (in the pre-comp) state, that will be a HUGE job.

It’s ignoring it completely.

About 165.

No.
I’m just wondering: Is there a way to easily “Un-precomp”…? That would solve my problem, I think.
Kind regards,

Yes, (see my answer to previous poster). If I turn off “collapse transformations/continouos rasterization”, I do in fact get motion blur, but I need that button checked!

Won’t help, motion blur is totally ignored.
Any other thoughts…?
Kind regards,

not a answer but a workaround; why not render your all your precomps so you have rendered stills in their scaled down version, then import them into project and ALT click swap them with the precomps.

Thanks for the suggestion, but then the rendered precomps will be pics with lower resolution, and I won’t be able to zoom into the pics and maintain quality. A pic which is originally 4000 x 3000 pixels and scaled down to fit 720 x 576 in a precomp, will maintain quality when I scale up quite a bit in the main comp if I have the continuous rasterization button checked in the main comp. By prerendering, I in effect make a new pic which only contains 720 x 576 pixels, and scaling up that new pic will naturally cause quality loss.
It’s starting to look like I just have to start the whole thing over, and apply my animations so that they look as close to the original ones as possible. A pain in the …, but I don’t know what else to do…Kind regards,
Eric
