Jittery Stills while in motion

I have stills in motion on my timeline and they jitter in playback, why?
Thanks
David

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. This can also be the case in scanned images with a great deal of detail in 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.

Still image with motion has flicker pulsating problem

I use FCP 5.0.4
I have read the many threads about this subject and am still not able to succeed in getting rid of the flicker/pulsating in a still image with motion.
I would say about 25% of the stills with motion have the jitters; all the rest look great.
The first thing I tried was
Effects:Video Filters:Video:Field Shift:none
as well as
Effects:Video Filters:Video:Flicker Filter min, med, and max.
Maybe 5% were corrected with this, but the other 20% still had the jitters even after using a combination of the above or by themselves.
I just burned a test DVD using a variety of the persistently jittery stills from my current project and although the jitters change a bit, they were still there so all of these failed:
1. Effects:Video Filters:Video:De-interlace Upper (odd)
2. Effects:Video Filters:Video:De-interlace Flicker Filter minimal
3. Effects:Video Filters:Video:De-interlace Flicker Filter max
4. Effects:Video Filters:Color Correction:Broadcast Safe conservative 115
5. Effects:Video Filters:Video:Flicker Filter max
6. All the tricks together which means
Effects:Video Filters:Video:De-interlace set at Upper (odd)
Effects:Video Filters:Video:Flicker Filter max
Effects:Video Filters:Video:Shift Fields: none
Effects:Video Filters:Color Correction:Broadcast Safe conservative 115
I know this issue has been kicked around a lot and i know some folks are not happy that it has to be kicked around at all. But I am doing something wrong because my DVDs look very un-PRO. Would anyone like to talk me through this nightmare preferably with as many details as possible since I am obviously missing something critical.
Thanks in advance.

There is no 'secret formula'. It just takes thinking through the issues.
1. Set the image size for each image that makes sense within the context of your project. Going significantly larger than the displayed area of that image (including movement) is just asking FCP to do additional work to resize the image. FCP is less sophisticated at resizing images than Photoshop. Use Photoshop and your planning of the movie to get the images to the appropriate size.
2. Wasted effort and totally irrelevant- you could set it to 7200 dpi if it makes you feel better.
3. Good idea - be sure to knock down areas of pure or very bright white. These are the elements that will give you the most trouble.
4. Don't do this unless you want to throw away HALF the picture information. Deinterlace deletes half the picture and then photoshop recreates it through interpolation of the remaining half of the picture. Why do this?
5. Make your determination based on what works. If you have properly exposed and sized the material, the need to blur is greatly reduced. ONLY do it on the images that need it. Why degrade every image if you do not need to do so?
6. See number 5
7. Lay out your time line early, view the work on an external broadcast monitor and only mess about with the images that require it.
In the psycho business they have term for much of the referenced post - it's called superstitious behavior. Basically it comes down to "It worked before so we recommend it to everyone without regard to their situation" ... here's another example:
Many years ago in my architecture practice, we had one of the early 512k macs (upgraded from the 128k!) I needed to show one of the interns how to create a project budget spread sheet in Excel. Inadvertently I clicked on Word, said "oops", closed it and opened Excel and we went to work.
A week later I was walking by the computer and overheard the same intern explaining how to work with Excel to another architect. "First you open Word, close it, THEN you open Excel", she explained. When asked by her 'trainee', why do you have to open Word first, wouldn't it just be easier to simply open Excel? Her answer was just perfect, "Well, it works every time, what's wrong with that?" so it goes ...
good luck with your project.

Applying widescreen matte to still photos in motion

I shot some footage for a documentary using my Canon XL2, 16:9 format. I'm adding some still photos using motion. Is it possible to apply the Widescreen matte effect so the photos match the widescreen look of my footage? I can't figure out how.

Use the Photoshop preset for DV/D1 widescreen as a template and paste your photos into that.
You will need to use Photoshop's Transform controls to frame your photos and have to decide what part of the top and/or bottom gets cropped off.
If you want to zoom or pan, use the original photos in Motion and make sure the photo fills the screen at its smallest size. Again, you will have to sacrifice the top or bottom of the photo to some extent.
If you absolutely must see all of the photo's content, consider using a complimentary background fill, perhaps with some blurring. Place your photo on top and shrink it down to within the safe area.

My iphone 4s Getting Over Heating While Playing Motion Games

I bought iphone 4s 3 weeks ago, It's getting over heating over heating on right side of silver coating while playing motion games or using wifi. Its normal or what can i do. Please help help me......................................,

does it get hot when you dont play the game? If it deosnt then there probable nothing wrong

Hi, I'm doing a poor man's morph project on my motion 4 . It works perfect while on motion , but when I try to import it to tcp it will transfer the photos but not the optical flow fx. what am I doing wrong?

Hi I don't know if I was able to send this question before but here it goes again. I'am doing a poor man's morph project on my motion 4 program, and it works great while in Motion, but once I try to import it to fcp, it will import the photos but not the optical flow fx, what am I doing wrong? I appreciate you help

Decided to use cmd A to select all the icons on the desktop and then looked for a right click option. There it was - the option to move to a folder. I now have them all in this folder which tells me it holds 157 items. Now you know why I needed to know LOL
Thought it might be of help to someone.

How to safely turn off the computer while the motion servo is still enabled?

When we use PCI-7344 and set it for serve closed control, I have found a very serious problem
in using the control card in this mode.
As the card is able to control motors only with the computer at power on status, but if we are very
carelessly to shut down the computer and without the notice to turn off motor driver power first
we would always get serious sudden moves of the motors, and might cause damages to the system. The same situation also applies to when control the motors under open/closed loop stepper mode.
How should I do to prevent the above situation?
(note: in my system, we have hook up relays and timers if we could set DIO bits before shut down
the computer. But
still, there are a certain occassions that the operator would still forget to set the DIO bits
and turn off the computer directly)

The Inhibit output pin of the motion controller (also called drive enable) is the best way to achieve this. It is basically a signal that most power drives take in as an active low input so that when the powergoes out of the computer, the line goes low and immediately kills the axis so that no servo ouptut command affects the motor.
Best regards,
Alex Games

Can you still use soft motion without the scan engine on crio?

Where are the trajectory generator property and invoke nodes in softmotion for LV 2011?
These functions are not longer found in the pallet? Are they no longer supported?
All the new soft motion examples are using the scan engine. Can I use soft motion without the scan engine????

Hi Ian,
I apologize that this wasn't stated in the release notes. While your code should have upgraded without breaking, the release documentation should have mentioned that the advanced trajectory genertor functionality is no longer supported. If you still want to use the trajectory generator functions, they are still shipped with SoftMotion, they are just not on the palette. I have attached a zip file that has 4 .mnu files that will get them on the palette. To install these, do the following:
Close LabVIEW
Make a copy of the following directory: C:\Program Files (x86)\National Instruments\LabVIEW 2011\menus\Categories\VisionMotion\_nism. In case something goes wrong, we will want to have a copy of this directory so that we can replace it.
Copy the 4 .mnu files from the attachement into the above _nism directory (the original, not the copy). If it asks you to replace any of the exisiting files, please do. You don't have to copy the readonly.txt file.
Start LabVIEW. You should know have the trajectory generator functions in your SoftMotion Advanced palette.
Keep in mind that we no longer support these functions. This means that they are not tested in new releases and any bugs will likely not get fixed.
I would recommend that you use the new API for any new designs. You can still get most of the functionality of the old API but without the complexity. If you want to generate setpoints at 5ms then you will run the scan engine at 5ms. This is certainly easier than having to do the timing yourself, but it does take away some control from the user. If you give me a brief overview of what you mean by synchronization, I will let you know the best way to do it with the new API.
Thanks,

Jittery photos when applying motion to photos in imovie...

I am using imovie 06. As I apply motion to my photos (eg. zoom, etc.), parts of the photo seem to be "jittery" or "sparkly". For instance, the large area of grass seems to sparkle as imovie zooms in, which is very distracting. Any suggestions?

This does not work. I have the same duplicate problem (since I updated to mavericks).
Whether you use the Option/Command keys or not, you still get the same dialog box as described above. You do NOT get the alternate box in which you described.
For the record: I am using a 2009 20" imac (running 8GB instead of the stock 2GB) that has all the latest updates as they are offered. I have always been able to open iPhoto prior to this upgrade.

Jittery/Still Video @ Transitions

I was unable to find this question answered in a search, so here goes...
I just completed my first video project (1:03 total time, includes video and still photos rendered with the Ken Burns effect) on iMovie HD and burned it using the latest version of iDVD.
I've noticed the video immediately preceding transitions appears either jittery or stops all together as the transition (usually Overlap) moves into the next video or still shot.
Is this a common problem that anyone knows a work-around?

This is a known problem although surprisingly few people have complained about it... Excluding me, I think you are the first to complain about this...
Yes! Some transitions have interlace-related flicker or distortion in iMovie HD 5.0.2:
The Overlap transition doesn't deinterlace the freeze frame like it should. If the freeze frame remains interlaced, then there is flicker or jitter when it is viewed on an interlaced TV.
Also the Scale Down transition doesn't deinterlace the scaled clip so it has ugly interlacing artifacts (if it is interlaced and if it contains motion).
It can be debated whether the Twirl and Warp Out transitions should also deinterlace the transition clip so there would be no interlacing artifacts. It is a matter of taste whether distortion in interlacing is part of those transition effects or not.
http://www.sjoki.uta.fi/~shmhav/iMovieHDbugs.html#transitions
BTW, NTSC users have another ugly thing about transitions:
In NTSC projects the very first frame of a transition is duplicated and the very first frame after the transition is dropped causing jerky movement. This is more apparent in some transitions than others. This bug doesn't seem to affect PAL projects.
http://www.sjoki.uta.fi/~shmhav/iMovieHD_bugs.html#ntsctransitions
But wait, PAL users have their own transition problems because in iMovie HD 5.0.2's transitions are always about 1.2x longer than they should in PAL.

Any ideas?

Hi Frank,
Thanks.
My HD is a "normal" HD, so I guess it's HFS+. (According to Disk Utility it is Mac OS Extended (Journaled).
The NAS is WD MyBook Live Duo. I just plugged into my Time Machine.
I am relocating using Aperture "relocate originals for project" under the File tab.
Ahh, thanks for the answer to question 1.
Yes, I am trying to relocate them, but tried different things to find the problem.
And the problem seems to be that when an image gets an extra attribute (when it's downloaded from the internet, when it is comes from a mail message) then Aperture seems not to be able to move the file.
I.e. Aperture presumeably asks the Finder or kernel to perform this task, and this then fails because of the extra attirbutes that were set.
I now found a way of manually removing the extra attributes, but that is a pain.
Think of this normal workflow:
- someone sends me an email containing images
- I move the images to my Desktop
- I then import the images into Aperture
- I then decide to relocate my images for that project to my NAS
Then is when this problem occurs.
So I just tried to relocate to another place on my HD.
That works fine.
I looked again at the error message.
And it says "could not set attributes com.apple.metadata:kMDItemDownloadedDate on destination file descriptor" .
So, yes, it seems like it has to do with the NAS not supporting setting the extra attributes.
And as long as there are no extra attributes on an image, there is no problem.
(Not completely true, but I have another thread about that)
Thanks Frank, I have to digest this a bit.

Control does not stay in case structure while using motion VIs

Hi,
I have a motion control card PCI 7344 connected to my PC. I am able to control the motor at the required speed till the required position using an encoder. Now I have put my motion control VIs in a case structure in such a way that, if Case1 is selected then the motor should to position P at speed S, if case 2 is selected then the motor should move to position Q at speed S and if case3 is selected then the motor should to position R at speed S. I am selecting cases 1,2,3 etc. by scanning a set of numbers seperated by spaces which look like this,
1 2 5 7 3
This number scanning is done using a while loop. Now, when the first number is scanned in the above set of numbers. The number 1 is obtained and the control is switched to case1. But before the motor reaches position P, the control switches to case2 and before completing the execution, the program scans case5 and so on. That means that the control does not stay till the move in the case 1 is completed. I'm sure there must be a way to retain the control to a case and stop the next number to be scanned before the functions in the particular are completely executed. I thought of one method, i.e. by using the move complete VI provided in LabVIEW, but I could not implement it. Please help me out with this.

Hi,
Our motion controllers allow you to preemptively start a move in the middle of a current move. For example if you are moving from point A to B and based on some logic, you determine you need to immediately start moving to point C. A preemptive move allows you to just load the new target position and call start. You do NOT have to first stop the current move and then start the new move.
In your case, you want the first move to complete before the second move starts. There are two ways to handle this. First, wait for the move to complete via a Wait For Move Complete function/VI call, or use the Check For Move Complete function/VI in a loop. Second, use Blend Start instead of the regular start. A Blend Start (if blend factor is set to 0) waits for the first move to complete before the second move starts.
Check out the help topics for Start Motion and Blend Motion to learn more.

Can we take photos still while recording videos on iphone 4s on ios 6??

Can we take photos while recording videos on iphone 4s using ios 6??

1. Open the camera app.
2. Move the slider from in the bottom right from photo to video.
3. Begin recording your video.
4. While your video is recording, tap the camera icon in the upper right to take a photo.
5. You'll see the shutter close on your screen each time you snap a photo.
6. Your photos will be saved to your camera roll.
Edit:
Just noticed you have a 4S...iPhone 5 only, sorry.

Canvas Remains Still While Output Monitor is Fine

Recently the Mac Pro station I work on was upgraded from FCP 6.x to 7.03. Noting that everything worked fine prior to the upgrade and everything works fine after the upgrade except this new problem:
When scrubbing the timeline audio and video playback fine on both the external monitor and the FCP canvas window. When I playback the timeline the output monitor works fine but the canvas window remains frozen on the first frame where the playhead was. As soon as you stop playback the canvas will update to the current and correct frame but it remains still or frozen during all playback except scrubbing.
Thanks for any suggestions.

Oops, sorry,wrong answer - let me try again:
Go to the menu Final Cut Pro > Audio Video Settings and click on the A/V devices Tab. Make sure "Mirror on Desktop" is selected:

Shooting stills while recording video with the SX50

Has anyone done this? I was shooting some video yesterday and was happy with how it came out until I realized that pressing the shutter button while recording video actually caused the video to insert a black frame and included the shutter sound. What is this?
My Kodak Z990 was able to do this same function (take pictures during videos) and even though some of them would turn out a bit blurrier than I would have liked, it never insert a black frame and sure didn't stick the shutter sound in there. Did Canon do this on purpose? I'm going to have to try and pull this video into some video editor to remove the frame and sound and hope it works.
Lesson learned, I guess. I'll take pictures and video separately from now on, just in case, but it's unfortunate that Canon screwed up badly on this feature.

Charleyhorse,
The items you mentioned need to be set before you start the video. Once the G16 is running the video, you cannot make adjustments to white balance, ISO, etc. The people I deal with all run the video for their G16's in Auto mode and let the camera make the decisions. But like myself, they don't use video very often, so hopefully someone with video experience on the G16 can give some better insight.
