Motion blur keyframing?

when adding a motion blur to a clip is there a way to keyframing it? In other words taking the blur up and down only on certain parts of the clip?

i know you can do that with the various blurs....but what i meant specifically was "motion blur" that is only avaible (as far as i can tell) on an individual clip in the viewer. Do you have to actually razor blade the clip and motion blur it in sections or can you keyframe it?
thanks

Motion blur is messing up my composition

Hey all,
I'm working on a project which involves 3d space (using camera tracker). Everything is going fine until I needed to turn on motion blur for a layer. When i switched it on for the composition, things start to get weird. If you play the video, the null objects visibly "rotate" instantly, move from spot to spot randomly, and it's obvious that something is not right. When i turn off the motion blur, the object right themselves.
Does anyone have any suggestions? I think i can work through it by creating a new composition then dropping the existing into that and turning on motion blur there, but i would rather be able to work with it in the same comp.
I'm working with 1920x1080p footage 30 fps in CS5.5 on a macbook pro 2.52ghz intel core 2 duo. If you need any other info just let me know.
Thanks
Dan

OK, here's my best guess. When you turn on motion blur time samples differently. The keyframes that are causing the problems are at a z rotation for the camera of 179º. This made me think you were experiencing a gimbal lock with your camera moves. When the camera gimbal locks the camera orientation flips. It has nothing to do with motion blur being enabled on the layers.
I seldom apply tracking data directly to a camera for this reason. I almost always apply the tracking data to a null then parent the camera to the null. This will prevent gimbal lock problems with the camera.
There is a solution that may work for you. Open up the composition settings, the Advanced tab and change the Shutter phase to 0º. This should prevent the gimbal lock that you're getting. I wouldn't call this a bug, but a better workflow would have prevented the problem in the first place.

Motion blur options?

Hello!
I'm working on a new project. Footage is being recorded from a game at 300 fps (then resampled to 30). I'd like to achieve the same motion blur as for footage take with a normal camera. I tried a few things but I'd like to see if there are some other options:
Plain frame blending from framerate resampling from 300 to 30.
Reel Smart Motion Blur plug-in without frame blend switch on. Looks pretty decent at first sight and renders reasonably fast. But under closer inspection it shows a lot of incorrect interpolation at a lot of elements.
Reel Smart Motion Blur plug-in with frame blending switch on. Similar to the previous example.
CC Force Motion Blur plug-in with interpolation switch on. Produces a great result at a cost of really long render times. Also i have no idea where to set the shutter phase (native shutter and interpolating dont work together?).
Are there any other options?
Thanks a bunch.

Hey guys,
its been a while and Im playing around with motion blur of high fps footage again.
I've tried the effect CC Wide Time which blends a designated number of frames before and after the current frame.
I have footage recorded at 1000 fps. In comparison frame mix would blend 40 frames into a single frame (1000 fps to 25 fps) which would represent a shutter angle of 180° (i believe). That doesn't look smooth enough in my mind, so in CC Wide Time i set the values to 80 frames total (39 ahead, 40 behind, 1 current just to be accurate ), which represents the shutter angle of 360° with a phase of -180°.
Now the problem is that i would like to time remap the clip. After a precomp i time stretch the clip to obtain the real life time scale - 1000 fps to 25 fps, with the motion blur i describe above. If i enable time remap and start playing with slowmotion the intensity of motion blur intesity (blurred frames) stays the same, which isnt right. A way to fix that would be to use a linear 40 -> 0 frames blended corresponding to the velocity achieved by timeremaping, but i cant seem to find a way to use clip velocity in expressions.
I could use timewarp and use speed value instead of time remap, but that seems like a pain especially when i think of applying ease to the keyframes.
To think all of this could be avoided if CC Force Motion Blur would offer shutter phase.
Any thoughts on the issue?
Thanks!

Motion Blur in PPro CC 2014?

Is there a motion blur option in Premiere Pro CC 2014? This is something that would be incredibly useful in a long-form documentary project with hundreds of moving images. Normally, I'd send a few images over to After Effects, but enabling motion blur on simple keyframe zooms in Premiere Pro would be a huge a time saver when there are hundreds of images.
Thanks,
jb

No, that is a job for AE but you can file a feature request.

Motion blur in FCP X?

How do I turn Motion Blur on for an image in FCPX?
I have a png supplied by the client that I am applying some movement to to and need to introduce some motion blur to smooth the motion a little, any ideas?
Thanks
Tony

I hope I am wrong but it's another short-coming of FCPX. I like to do speed ramps (which don't work nearly as well as FCP7's Time Remapping) and I can't add motion blur to the shot.. and sending to Motion5 is not streemlined eaither.... Bummer...
Other gripes:
KeyFrame Interperation for ANY keyframes. NOT THERE
Drop Shadows for PSD or other GFX files (only for text)
Bad Organization of Projects
Lack of user control
(so many more)....

Standard motion blur on 3d camera uses premature frame samples

Hi there everyone, I was wondering if anyone has ever noticed the following issue:
I have created a couple of 3D layers in AE "space", having a camera zip panning and tilting from one to the other. We're talking like 15 frames rotation moves, so worth a little blurring. Now AE creates a very nice motion blur on those zippy camera moves, be it that half of the sixteen samples needed to calculate the motion blur are taken from the frames yet to come (?????) So, especially in a 'banking' kind of rotation, causing an over time calculated spin blur, the blur itself pops in even before the camera has moved (it's like five frames 'ahead').
Does anyone of you have a similar experience? Is there a workaround without having to create every blur manually?
Oh, by the way, CC Force Time blur crashes on this because it does not like certain effects I used, like Text Anarchy and a couple of standard AE effects (??)
Please help me out on this one. It's easy to recreate this issue: create a new comp, throw in a camera and a video layer and have this video layer rotating round its Z-axis once in a five frames duration, in linear interpolation. Now switch on motion blur for this layer and the timeline. You will notice the blur appears before the video layer has started rotating and when the rotation has stopped, the motion blur is long gone. Appreciate any help, thx.

Hi Mylenium and thanks for taking the time. I appreciate it a lot, certainly when a known AE guru like you picks up a question like this one.
Unfortunately, though I have tried every offset in steps of 90 degrees up to 720, but the problems persists. Maybe a bigger offset helps? Or a negative one (if possible, haven't tried yet...)
I don't think this would be of any importance, but the layers I use are mainly AE generated text layers.... but now that I think of it, the entire camera move was imported from Cinema 4D, so every timeline frame is a lineair camera keyframe as well... 546 frames, and thus 546 keyframes for the poor 3D cam... could that be messing up the motion blur calculation.....?
I guess I will try that right after dinner. Thanks again so far, I feel honoured.

Motion Blur Problem/Potential Bug

Hi,
I am having a problem when motion blur is activated. My comp. consists of media moving onto screen and 3D cameras moving in and out of the composition. When motion blur is activated the desired effect is created, however when the cameras move in and out on the image (with motion blur activated) the anchor point appears to be affected and it is sent behind the background. The only way I have been able to make the image visible is adjusting the anchor point, but I wanted to figure out if this was a known bug before I do this throughout my entire project.
I am running Windows 7 Pro 64-bit with After Effects 12.2.1.5 on a custom build with i7 3.5Ghz, 16GB Ram, and a NVIDIA GeForce GTX 680.
If anyone could give me an idea on if this is a bug that will eventually be addressed or if there is a solution other than adjusting anchor point please let me know.
Thanks,

I have done quite a bit of research today as to whether this was a bug or a mistake I made and this has happened to other's in after effects, however I got no productive information on if it was a bug or a mistake. To address the other topics you brought up:
1. I am quite aware that only one camera can be active at a time, and yes I have multiple cameras that are active in differerent sections of my composition, none overlap each other however.
2. And as far as the anchor moving by itself, it is not necessarly "moving", the anchor position data in the timeline does not change and have no parent or active keyframes. However for a number of frames the image disappears behind the background giving the impression that the anchor point is changed. The reasoning for why I intially thought there was a bug was the image would disappear in the middle of its motion and reappear toward the end of it's movement.

How to motion blur an object into a scene?

I am using match move to attach an image to an object in my video. The object sometime moves around enough where there is significant motion blur. Obviously I need the image that I am adding to match this motion blur. The motion blur filter doesn't seem to work for this (at least by itself). All it does it make the image blurry within side of the bounds of the image. The motion blur in any given frame is happening along a path, and the image needs to be stretched along that path as well as blurred into the background. How do I accomplish this effect?

Hi,
You can turn on motion blur. Have a look in the view menu to turn this on. Have a look in the project properties to set the number of samples and shutter angle. However this is a per project setting rather than by layer.
Or you could a directional blur and keyframe the amount as you need.

After Effects CC: Motion Blur, 3D Layers and Opacity

Hi All,
I've had this problem for a while now (it happened in CS6 as well).
I'm animating vector layers from Illustrator (continuously rasterize on). When I apply a camera, 3D Layer and Motion Blur I have a consistent glitch (or maybe not a glitch but conflicting variables).
If I simply animate one layer from 100% opacity to 0%, and another from 0% to 100% from keyframe : 01 to : 02 (switch off, not fade) the top layer lingers with transparency for an extra frame - it doesn't switch off cleanly.
This creates frustrating issues which I have worked around once I go into Avid, but I'd greatly appreciate some advice on how to avoid the issue altogether. It's particularly frustrating if I am trying to do a smooth camera move and I have have a lingering frame.
Thanks.

Motion Blur help.

Alrighty, I'm using Photoshop CS4 Extended, and I'm having troubles with motion blur.
When I set the angle to anything above 60 really and distance to about 300 it crashes saying Adobe Photoshop CS4 has encountered a problem and needs to close.
This happens every time. So I tried restarting Photoshop, then restarting my computer, then I uninstalled and reinstalled fresh and it still crashes when I begin to use motion blur, infact I believe it even crashed just by opening the motion blur window for over 40 seconds.
Any help or ideas?
Thanks in advance!

Thanks a lot Mylenium! I'll do that in a few minutes, by the way heres an update with some more information.
Photoshop crashes when I change the angle to 49 or higher, anything lower is fine.
I went to my event viewer and I found this:
Faulting application photoshop.exe, version 11.0.0.0, faulting module mmxcore.8bx, version 11.0.0.0, fault address 0x0000d62a.

My text moves to the wrong place when I apply motion blur!

Hello friends! thanks in advance for any able to solve my problem. when ever I apply motion blur to moving text it repositions the text permanently.... I have to delete the motion blur effect in order to have it text stay on course...any suggestions?

"Delete the motion blur effect"? Sounds like you are applying an effect, rather than turning on motion blur.
Please provide a detailed explanation of the process that causes the problem. If possible, post a screengrab as well.
Note that Motion Blur, at its core, does alter the position of animation by blurring the disnace between two moments in time. When you activate motion blur, it samples the position of your text at multiple points in time to create the illusion of motion blur. If your text is moving very fast, the results can be surprisingly major.

How do I select an image with motion blur so that I can put it onto a different background ?

How do I overlay a image with motion blur on a white background (like the first image) onto a different background (to look like the second image)? any help would be greatly appreciated, many thanks ,ed

I’m afraid you may have bitten off more than you might want to chew.
The resulting pixels of an in-camera-blur combine information about the color/brightness of back- and foreground (edit: the result of surface properties and lighting conditions) with motion (basically transparency for this task) in such a way that it seems exceedingly difficult (maybe even improssible) to isolate the foreground in a »pure« form.
One may get a halfway decent mask (as the backgound is at least almost uniform and brighter than the foreground elements) but you may have to manually decontaminate the transparent areas, otherwise the masked object in front of a dark background would have a bright edge.

Motion Blur doesn't work in Final Cut Pro

I've been working on stuff and int he past Motion Blur worked and now when I use it the motion blur has refused to work as a preview or after I render it. Is there something i'm doing wrong that's making it happen?
I'm using Mac OS X Leopard, the latest final cut pro and i'm using blue and green screen and Chroma Keyer and image control sinc ei'm making a sillouette and it's worked for me before.
If someone can reply and suggest anything that would be awseome.

Does your object to be blurred actually move...if not then use a blur filter
When you check the motion blur box and click the disclosure triangle what is the Blur percentage? did you try increasing it? If so does it make a difference?

How to add motion blur to the shatter effect?

I am trying to add motion blur to the shatter effect, iv created my own custom shatter map with text that remains after the effect is complete, i have tried to add motion blur through the other blur effects and i have not found one that will do the motion blur correctly.
what im wanting is for there to be motion blur on the pieces that are shattering, any suggestions?

There are suggestions toward the bottom of this page, including a tip using the Timewarp effect. I found this by searching for 'motion blur'.

Imported video has "motion-blur" artifacts, but original is fine.

Hi,
I've just purchased a Samsung SMX-F30 standard-def camcorder. I've shot a few clips and decided to test its compatibility with iMovie. iMovie recognised the camcorder with no problems and imported all my clips without any hassle. However, when I play the clips in iMovie if the clip has any motion, say an arm or hand being waved or head moving, then the image blurs in a way I can only describe as "interlace staggering". That is, alternate lines in the fram shift position left and right alternately. This is really annoying as you can imagine!
A few details about my setup other than the machine details below:
Clips recorded in 4:3
iMovie defaults when importing
iMovie version is 8.0.2 (I think)
iMovie imports to an external firewire 500GB hard drive
Clips not analysed for stabilisation after import
Camera records in "H.264/AVC Format" according to the manual
Recording at approx 5Mbps
Camera was using built-in electronic anti-shake
I hope someone can suggest a few things to try as I've just returned to movie making after owning a Mini-DV based camcorder 10 years ago!
Thanks
Stuart

His book gives specific directions and more info on AVCHD with frame rates and bits...so definately buy the book. Your question: It kinda depends on your set up. Many people need to import into imovie 9 just so they can get an editable copy of the footage. So then you make your way over to the events folder and import the events into another program for turning it into progressive and de-interlacing it. You have to becareful because you will have duplicate footage.
He goes into details on how to do this. I have a different workflow because i import on a different machine using imovie6 since i am working with tapes. Then i convert it before i import it again into imovie. My DV footage doesn't get motion blur though so i am only doing this workflow to ensure no quality loss.
