Fast motion blur/ghosting

i have seen various posts on problems with slow motion where it creates a ghosting/lag/blurry eye hurting product. I have seen responses to this problem via changing the motion blur attributes in the video tab.
I am seeing a similar effect when i speed things up too. Is it the same answer?
how can i get rid of that seizure inducing lag/ghosty problem when i speed up video in FCP?
please help, deadline imminent!

Turn off MOTION BLUR when you make the speed adjust.
Or use the Nattress 50% filter. www.nattress.com

  • 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.

  • 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 caused by Shutter Speed 50?!

    Hi All,
    I'm a GH2 user. Shoot in 50i-50ss-5.6f. I realized that is an effect such like "Motion Blur" which caused by the low shutter speed as I mentioned (50ss). Search around some forum, it is quite common. In fact, it looks not really comfortable to me! How do you solve this issue or perhaps reducing/smoothen the motion blur issue?
    Picture like focus clear & sharp while talent do not move to left or right. Once his/her head move to left or right, there is motion blur after it. In fact, facused while talent did not move his/her head then.
    Thanks!

    David,
    Thanks for the prompt reply and confirmation.
    Perhaps, 1/50 producing slow shutter speed result--motion blur? It just like a man walk from left to right in front of my cam, and the man will be blur in motion during the recording. It'll only stay focused while the man stop and stand still. Double up the shutter speed will helps this? like 1/100? Might need your opinion.
    Some friends ask me "are you shooting a speedy subject?". Not really that speed or fast. Just like what i've mention above, perhaps just walking...turn around...hand up...those might blur in 1/50 shutter speed with fully Continuos Focus Function.
    I'm just curious, how could those GH2 friends shooting a Dance Genre Music of MV? They are dancing, moving fast enough...but, surprise, MV is just sharp and stay focused on every person! What do you say?
    Is those below's MV consider pretty smooth? Can you tell what's the shutter speed on those? Continuos Focus + Manual Focus in use?
    Thanks for now and hear from you soon! Apprciate to your precious time to answer

  • Motion Blur not working in AE CC

    Using AE CC on a MacBook Pro, adding motion blur to a fast-moving footage layer in a comp. Both the comp and layer motion blur toggle are on, but no blur is added. Force motion blur has the same non-result.

    Make sure the layer is moving. Make sure you are not set to draft. Show us a screenshot and we can probably nail it down in 2 seconds.

  • Why no Motion Blur when animating a camera?

    I think I'm in trouble. I'm finishing a project where a logo (let's call it a box) was built by creating all the sides using solids, then making these solid layers 3D. I then move the CAMERA around the box. That seemed to be a lot easier than trying to move all the 3D layers in front of a camera.
    I cannot get any motion blur effect when the camera moves fast. I've tried numerous settings (and of course have the layers enabled for motion blur). Is it not working because the layers aren't in motion? Can I acheive motion blur by animating a camera around 3D layers?

    Thanks, but I do have motion blur on for the composition and the layers and the render queue. There is no "switch" to turn motion blur on for a camera layer, and of course no 3D switch for a camera because it's inherently 3D.
    I used various motion blur (advanced) composition settings, as well as adjusting the camera's apature, fstop, focal length, focal distance, etc. Can't seem to get any motion blur effect. The camera occasionally whip-pans, slows down, speeds up - so it's certainly moving fast enough.
    Just wondering if I should have created a Null layer, parent it to the camera and animate the Null because that does have switches for 3D and motion blur.
    Why wouldn't motion blur show when animating a camera around an object?

  • Fast Motion unsmooth shots ; PLEASE HELP

    as when shots are in slow motion...fast motion creates shaky ghostiness too with the footage (i wonder how technologically incorrect that term is).
    how do i reduce/fix this eye-piercing problem when i increase speed of my footage.
    please help.
    deadline imminent.

    Denis Murphy wrote:
    If you shot this footage with the wrong shutter speed, however, there's not much you can do to make it look good in slow motion.
    If that's the case, I've found that doing motion blur on it after the fact can help...

  • Keylight and Motion Blur, orange over green

    I'm making a series of videos of basketball players for a website.  I'm using Keylight to remove the green screen.  I seem to have gotten the parameters where it gives fairly good results with the player.  My problem is the basketball.  It moves fast in front of the green screen that there's a pretty serious motion blur problem.
    What I have tried is making a copy of the video on the layer above and then masking only the ball when it is by itself in front of the green screen and processing it giving it it's own despill values, and then using that mask as a track matte for the layer below to drop out the basketball from the player's layer when the ball is in the air.  That does improve things a bit, because I can tighten up the image on the ball a bit.  But there is still a sizeable brown smudge where the orange ball blurs over the green screen that I can't seem to get rid of.
    I'm not sure what else I can do, and I don't have the time to experiment with methods, or do painstaking minute correction.  Does anyone have a solution?
    Thanks.

    > <
    Unfotunately, there is no way to remove the image blur that is caused by your imporoperly shot footage; you needed a much faster shutter speed, appropriate for the subject, 1/250 or maybe even 1/1000 second.
    All you can do now is fake it and hopefully sell a new design concept, something a bit stylized. Masking off the ball is a good first step and now you can fill that mask with just about anything. I'd suggest a stylized animated basketball with glitter and sparks and lightning, simple clip art, or a photograph of the team's special logo-emblazoned ball, if they have such.

  • Slow motion / fast motion in Premiere Elements 13

    I read that in Premiere Elements 13 fast motion (and I think also slow motion) ist removed. Is that correct. And if yes: Is there any workaround available?

    rr
    Thanks for the reply.
    Great information. If you have been using Ctrl+R, that is the keyboard shortcut that brings up the Time Stretch dialog.
    Time Stretch (use of the Ctrl+R) has not been removed from Premiere Elements 13 Expert workspace.
    Like Premiere Elements 11, Time Stretch is found in the Expert workspace and not in the Quick workspace.
    When you use the keyboard shortcut Ctrl+R, I get Time Stretch dialog from where I can create the slow or fast motion effect in the selected clip.
    The following relates to Premiere Elements Timelapse Capture (Stop Motion) which has been removed from
    Premiere Elements 13 as a specific feature that you see in Premiere Elements 11 and 12.
    Adobe Premiere Elements 11 * Capture stop-motion and time-lapse video
    Please let me know if you are OK with the above information.
    Thank you.

  • 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.

  • 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'.

  • Slow/fast motion?

    I am a super beginner with imovie but im getting pretty good at it and im almost done with my movie but all i have left to do is make something in slowmotion and something in fast motion. does any one know how to do that and can explain 2 me how?

    That is not possible within iMovie '08. Here is one way of doing it:
    - Select just the section of the video you want to slow down, and export it as a Quicktime movie.
    - Download and install iMovie '06 from Apple. It's a free download for iMovie '08 owners.
    - Create a new project, import the clip, add it to the timeline.
    - Find the slow motion effect, adjust the speed of your clip.
    - Export result back out.
    - Import edited clip back into iMovie '08.
    - Splice it into your iMovie '08 project.
    There will be some quality loss as you will go through some format conversions along the way.

  • 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.
