Jittery Images

Hello,
I am producing a short movie with a lot of images. I am doing the Ken Burns effect on most images although I seem to be running into an issue of the images jittering on screen when I keyframe a zoom in or zoom out on the image. Any possible solutions? I have seen this before but, never really came up with any conclusions since I just replaced some of the images. Thanks.

If these images are higher than your video resolution (720x480??) then it is often helpful to add some Vertical Motion Blur in Photoshop or Gaussian (very little) Blur in FCP.
This process minimizes (hides) the aliasing caused by interlaced video.

Native HDV Jittery Images in Self Contained Movies

Hello,
I am having problems with HDV footage captured in native HDV 1080i60
When we output footage as Quicktime Self-Contained Movies the result is very JITTERY images.
Whereas when we print to video directly from the timeline, there is no such jittery effect.
We are thinking that it may be a conform problem with the keyframes in self-contained movies.
Any idea why this is occurring?
Thanks,
Marc Griffin

I'm having a very similar problem. Here's what I did.
1.) Edit my awesome HDV shot and HDV edited project.
2.) Export as a self-contained movie to transfer to another workstation for printing to video
3.) On other system open self-contained video in FCP and "print to video."
The process completed successfully, but when played back from tape, the footage is jittery. The self contained movie itself plays back fine in quicktime. I was wondering if it has to do with the compression of frames and what fcp does in the conforming process. Would ticking the checkbox "recompress all frames" fix this problem? I have not yet tried that as everything requires rendering. And even on a G5 quad it takes 25+ minutes to render / conform the video.
Thanks,
Kjell

Jittery images in menu

Never had this problem before. And I've got no idea what else to try.
I'm using a handful of still images in this DVD menu interface. Some are from a digital still camera. Some are video captures. But they're all jittery in the menu — not as I create the DVD — only after I burn it. And they're jittery +on my laptop screen+.
I've made sure the motion attribute isn't longer selected. I brought the images into Photoshop and exported them for video. But the jitteriness is still there. The only thing I haven't done is diminish the sharpness by putting a blur on all the images — it might help but the cost seems too high.
The odd thing is, I don't ever recall this happening before. The menu consists of one large background image and 4 smaller buttons. No text. All the images seem in flux between one field and another. Can't figure how to work around it. Ideas?

the images seem in flux between one field and another.
Try deinterlacing copies of the images in Photoshop to see if this is in fact an issue with the fields.
If your images are now stable, download JES Deinterlacer free, here: http://www.xs4all.nl/~jeschot/home.html and perform a field blend deinterlace on the images, this will give you better results because unlike Photoshop's deinterlace, it does not throw away half of your image.

Jittery image on VGA projectors with MBP

Recently I have had trouble projecting presentations from my MacBook Pro (15", early 2011, OS 10.8.3, 8 GB RAM) to several different VGA projectors. I am using a mini-Display to VGA adapter and use 2-screen mode (not mirroring). Initially, everything is fine - the projected image looks clean, but after a while, lines start to zigzag and jitter - as if someone was physically bumping the projector (or like a bad TV signal). This gets progressively worse and makes it nearly impossible to give a professional presentation (which I am required to do for my job). I have bought a brand-new miniDisplay-VGA adapter - no improvement! I am very careful to make sure that connections and cables are all solid. The same problem does NOT exist for external monitors hooked up via DVI or HDMI adapters/cables. Any suggestions/ideas?

First I tried flicker filter, and it helped some of the photos, but others became even worse! (The entire image shakes now instead of just portions.) I removed the flicker filter and tried the de-interlace filter, and that produced about the same results. I would try editing the photos separately in Adobe Photoshop, but before I delve into that I would like to set up an external video monitor. Unfortunately I've wasted about two days, and I can't seem to get it to work. I first tried by connecting the iMac to a Sony camcorder and connecting the camcorder to the video port on my television. No joy. Then I tried connecting the iMac via a mini-DVI to video adapter to my television. I thought my old television might be the problem, so I connected instead to the video port on a projector, and it still didn't work! I've changed the display settings and deleted certain preferences files, to no avail. My iMac doesn't seem to recognize the external display. I'm beginning to doubt this Mac purchase. Thanks for any help you can provide!

Final cut express gives a jittery image on my G5 iMac

I asked a similar question before and got some useful input but the problem still exists. When i enter a still image then zoom in with the motion tools in FCE the image moves around unevenly in the frame. When I Render the images in the Timeline, the problem gets even worse. I tried this with the same images on my old G4 450 with FCP 1.2 and it worked just fine- the way it's supposed to. Could there be a system problem with my iMac G5?

Jittery Image Motion

Hi,
I have an image (photoshop) which has thin black lines against a white background, and (as expected), it flickers when motion is applied. The de-flicker filter just adds a blur, but I was wondering if there's a way to actually thicken all the black lines? Is there a filter or combination of filters that can do that?
Thanks,
Lawrence

The flickering is an artifact of the interlaced nature of video. It is a result of very thin (often horizontal) elements that exist on one scanline as is common in text or titling (and your photo). This can also be the case in scanned images with great deal of detail with high contrast.
As the alternate fields play, the flashing element is essentially being turned on/off. The basic strategy is to get the element to exist over two scanlines so it is refreshed every time the field plays or to reduce the amount of contrast so the difference between ON and OFF is not noticeable.
Things to try (In increasing order of image degradation)
• (in FCP) field order>none
• (in FCP or Photoshop) reduce whites by 10% - reduces overly bright areas
• (in FCP) flicker filter - minimum
• (in Photoshop) motion blur>vertical> .2 - .5 pixels - blurs vertically only
• (In FCP or Photoshop) Gaussian blur> .2 - .5 pixels -blurs both horizontally as well as vertically
• (in FCP or Photoshop) deinterlace - throws away half the image and is generally not appropriate on scanned images
Remember: Unless you are viewing your work in the appropriate external NTSC/PAL monitor, you are playing blind. The computer monitor only shows you a proxy image.
good luck.

Jittery image

I have limited experience with FCP so I am sorry to take up your time with this question.
I already have one project on the go which when I preview looks fine, the image is as it should be and each clip of the movie plays through successfully.
I have just opened a new tab to make a new edit of the same material, and when i cut and paste clips from the old to the new tab and play them back, the image pulses every few seconds. Different clips pulse to a different degree, but in general they all have a problem.
Please could someone help me outta this jam
thanks
kP

have just rendered all, and some of the clips are still pulsing every other second. Its only slight, but definitely doesn't happen on the other edit...help much appreciated...

Save an unencoded iDVD disc image to encode/burn with Toast?

Hi:
I'm geting jittery image on playback (only in certain scenes) when I use iDVD to encode my disc. If I use Toast to encode and burn, there's no problem, using the same blanks and burner. I saw a post here from someone who said you can save a disc image from iDVD, but then have Toast encode it and burn it; in the help files it always says iDVD encodes its disc images. Any ideas, or any other suggestions as to the jittery playback on a few scenes?

It could be the DVD media you're using or player, etc. If you create a disk image and use DVD Player software to view it, that should be pretty much what to expect on DVD-R playing in a good quality DVD player.
Read Beverly's comments here:

File/Save As Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Disk Utility to burn the DVD.
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (not the .img, the one below) in the left-hand window. Click the Burn icon. Your SuperDrive tray will open. Insert a recordable DVD. (DVD-R preferred by me.) Click the Close button. Wait. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and Tiger.
b Also, you can use DVD Player to play the virtual disk to check your iDVD 5 project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

thanks.eva

You will most likely get answered if you repost this in the Final Cut Studio Forum. This forum is for Final Cut Pro X only...

QT files corrupted?

I cannot make QT files thru FCP anymore without what some call "artificating", jittery images and glowing high contrast areas. No idea how it started and nobody has been able to help, I took it to 3 apple stores and couldn't get an answer. I can still make QT files thru other apps though. I am considering a reinstall. Any other suggestions appreciated, also referral to anyone who could help?

Waited till after Christmas; I have an undoubtedly ancient system, Mac G4 tower, 867mhz, 512 ram, 2 x80G hd, this was "hot" when I bought it new. OS is 10.2.8 I use FCP 3.04. QT is 6.5. I have used this system without many upgrades or add-ons, and haven't really changed any settings that I know about. I could have mistakenly changed some as I don't use FCP on a regular basis.
I played with it and FCP movie seems to come out fine, but QT has odd artifacting, like I see on some YouTube videos. I changed a QTsetting to Best Quality and the artifacting was about 70% less, but still noticeable.
I use FCP projects to go to iDVD4 only because it's the only dvd burning program I have. Maybe occasionally a 2-4 min clip for internet. I think that's where I may have messed up and changed some settings without knowing what they were.
QT compression is video, quality is medium (although high gives less artifacting) Format is uncompressed, sample rate 44.1, sample size is 16.
Prepare for internet streaming is checked. Is this wrong for a QT file to go to iDVD4?
Maybe all I need to burn a dvd is to use FCP movie?
Since I'm on strike, I'll be using FCP alot more now, but budget disallows upgrading too much.
thanks for any comments...

QT file corrupted?

Posted this in FCP, then saw this forum, I am getting what some call "artifacting" in QT files thru Final Cut Pro 3, this started awhile ago and produces jittery images and high contrast areas. I went to 3 apple stores, nobody could help me, have posted on various forums and no solution. QT does work fine thru other apps so FCP seems to be the only one that produces the odd files. Any idea of where else I could go is greatly appreciated.

Believe it or not I know a few editors (using DV) in Hollywood who still use old g4s (=>450mhz), they were some of the best/stable computers/software Apple ever made before the big move to the new code.

Maybe I'm missing something. Are you capturing from a camera? or opening files .mov? mpeg? You do not want to recompress the file, persevering the original format is paramount until export.

It's what I prefer.

If so, I know several who are being affected by the strike. It's a sad state of affairs. Everyone is looking at different avenues to generate income. You might take a looksie at internet television as an option it's where I'm helping a few here in Hollywood with:

FCP 4: NTSC monitor image FROZEN/movie plays JITTERY in canvas window.

Hey guys. This started yesterday. Every time I hit play, the image from the frame I began playing at on the timeline remains frozen on my NTSC monitor, while the movie plays jittery, roughly, totally unsmoothly in the canvas window. I'm pretty sure I've tried all of Shane's answers, but right now I'm stuck. Any help is immensely appreciated.
PowerPC G4 Mac OS X (10.3.9)

Shane's stock answers addresses this, but make sure
that under the View mene that you are set to "All
Frames" and not "Single Frame"
Yeah, I had that covered from the beginning, but this sucker is stuck on whatever frame I begin to play from.

Fix for jittery jpeg images in FCE?

Hi,
I recently created a 25th wedding anniversary video for a friend of mine. Basically, I used jpeg images to which I applied motion (slow zooms, pans, etc). I noticed that when I rendered the movie, I got some jitters through some of the edit points. I rendered and re-rendered, but the jitters remained (they were in exactly the same place through the various conversions: eg. in the QuickTime movie and on the final DVD). Very frustrating. I normally edit on a preset canvas for HD, and don't have any problems. However, this time I selected 720x480 DV/DVCPRO - NTSC, since I didn't want to use the full size of 1920x1080 HD resolution ( mainly because I also incorporated some captured clips from VHS tapes).
Did I select the wrong preset for the canvas? Could this be why I'm getting the jittery edits? Or, perhaps it has something to do with timecode? I'm not very technical-minded; don't have a clue, in fact. Anyone have any experience with using jpegs in your movies and overcoming jitters? And, what preset for the canvas should I use for these kinds of projects?
Thanks very much!
Vic

Try using the De-interlace Filter on them.

Horizontal Scrolling Image JITTERY?

Hello, I just made a simple flash movie with one 3000 pixel
wide jpeg scrolling from left to right, I am using about 500 frames
at about 20 frames per second to scroll it using a simple motion
tween.
There is not much to this movie, but the image is jittery and
does not flow SMOOTHLY - any ideas how to to do this? Speedint the
frame rate up helps some, but I really need this to move slow.
Thanks

great, glad you were able to find the problem. Whoa, that's a
big image. Flash has a limit of 2880 for bitmaps and so on...
beyond that it's good luck, most of the time will throw an error. I
would think about getting the size down some, you could break it up
into pieces and bring them in and get rid of them when needed. btw-
what resolution is the image(dpi)?
2172, was an example, the ending position should be
determined by where you placed the image in the MC (center or at
0,0 ... ?) if positioned at the 0,0 it should start at 0 - width,
and end at 0 for left to right travel.
right, changing speed is fine, the number represents the
number of frames it will take to travel the distance, frame rate is
not effected by this. Leave it at 30 fps.

Jittery output image to projector

I am using the iMac video output to feed a 1x4 VGA splitter going out to 2 projectors (front & rear). The image on the front projector is jittery - the rear image is stable. This only occurs with the iMac. I've tested it with my Macbook and a DVD player and the front projector image remains stable - except with the iMac. I've tried using all the other outputs of the VGA slitter with no change. Any other ideas?

It would be easy to do this via a servlet but we want it to work offline as well as online. We don't want to display it in the applet as it doesn't contain a GUI and we want the interface configurable completely in HTML. Excluding these most obvious solutions, any other ideas?
