What causes blurred video, I'm using a 1411
I am using a VCR as my video source. Using a HL Grab acquisition. Performance is great. Once in a while my image gets blurred. I'm including a sample. Also, I am seeing a bowing of the image toward the top. What can I do? Thanks!

The blurred image looks like the odd and even fields have been reversed. I'm not sure why it happened though. The bowing at the top of the image is related to the timing signals. I suspect both are related to using the VCR as the source. VCRs do not produce high quality video signals by nature. Perhaps a higher quality VCR would help.
It might be worth running the same section of tape twice to see if the blurring occurs on the same frame every time. If it does, it is something on the tape. If not, it is the VCR.

Lately, I've been getting a blue screen in the midst of working and have to do a cold reboot to end it. Seems to happen when I'm closing windows or quitting applications. Not always, but sporadically. What causes this? I'm using 10.6.8 on early 2011 MBP. Thanks for any help/advice!
You have 10.6 on that machine, I suggest you stick with it for performance, third party hardware and software reasons as long as possible.
Consider 10.8 (not 10.7) when it's released, because 10.7 and 10.8 will require a new investment in software and newer third party hardware as it requires newer drivers the old machines won't have. (forced upgrade because of software, really nice of them)

Far as your Safari problem do these things until it's resolved:
1: Software Update fully under the Apple menu.
2: Check the status of your plug-ins and update (works for all browsers) also install Firefox and see if your problems continue. You should always have at least two browsers on the machine just in case one fails.

What kind of videos can I use?
I had a question, what kind of videos can i upload onto a new nano?
See, I have a DVD of my family reunion, someone video taped it and put it on DVD. Is it legal to use that DVD?
And I was wonering...if so, how do i get it onto the ipod? I have never used an ipod with video...so the itunes part is completely new to me.
Just to tell you though, my XP does not play dvds....any suggestions?Whats t&c?
Anyway in most contries your aloud to make backups of your DVD and rip them to watch on your iPod.
Programms which do that include Handbrake and VisualHub.
But if its a DVD you burned yourself, you should be able to convert the files on the DVD with either Quicktime or iSquint without any of the other programms.
iSquint is great much faster than Quicktime and free. -
Blur video frame with NI PCI-1411 and JAI CV M-300 camera (urgent problem)
Hello,
I am new with Vision and I need some advice with a problem, which I encountered.
I have a computer with integrated NI PCI-1411 board, which is connected to a JAI CV M-300 camera. I am measuring a steel part which is positioned in a dark chamber. The part is put on a glass board and is illuminated from underneath with light.
The part is moving. I have to measure this part when it reaches the camera region. I have made a test with not-moving part and everything is perfect. Now, when I move the part I get blur frames from video (with these no part measurement is possible). I need specify, that the camera has no trigger, so it makes video all the time (this video is later inspecting with Vision Builder).
I have tried to change parameters in MAX, but no involvement. I have found no proper icd/file for the camera.
I also could use a SONY DXC-950P camera, if this is better.
How can I eliminate the blur from video frames? Or what am I doing wrong? Is the camera not good enough? Camera + trigger would get better images.
I have attached the video frame with moving object (static) and the blur video frame with moving object (dynamic).
Please give me a answer or ideas as soon as possible.
Thanks.

dinamic.jpg 421 KBYou are using an interlaced camera. It takes half the picture (every other line), waits a split second, then takes the other half of the picture (the other lines). When it puts the two images together, you can see the two positions it was in when the images were taken.
The best solution is to use a non-interlaced or progressive scan camera, which takes the entire image at one time. The Sony might be this type of camera, since it has a P in its name. I didn't look up the specs.
If you can't get the right kind of camera, your only other option is to use fields instead of frames. One field is the half image taken at one time. The image will be half the height of the original image, though, which can mess things up.
Another possibility is the reduce the resolution of the image. If you take every other pixel in both directions, you will have a very clear image that is half the size of the original. You can do this with Extract in LabVIEW, not sure if it is available in VBAI.

What causes jumpy video playback
I've noticed that some clips in my (iMovie HD6) jump around. Could it be that the tape (I use Sony mini DV) Premium) is slightly sticking or what else could cause the problem.
Please help. Thanks.In the top middle of the Canvas and Viewer is a percentage button. Open it and make sure that "Fit to Window" has been selected.
If it hasn't you can tell because there will be blue scroll bars along the bottom and side of the window. -
Disk Utility stopped repairing the disk. I was instructed to backup as many of my files as possible.reformat the disk and restore my backed up files. Since I use time machine, can I assume that all my files and programs can be restored from my recent back ups?
Hi jeromefrodia,
Welcome to the Apple Support Community!
I understand that you are concerned about your data before reformatting the disk. Because you use Time Machine your information should be safe. Please refer to the attached article for information about what Time Machine backs up and how to restore from that backup.

What are the video effects used in this video
I was just wondering if anybody could help me. I was intrigued to find out what kind of video effect is used in this video at 0:16 - 0:18 and if theres a name for this type of video and editing used throughout the video such as the continous stream of different videos etc.
Do you mean the distorted lips or the bad tv reception.
The distorted lips can be anything from Bulge to Mesh Warp to Liquefy.
The bad TV reception can be started with the Bad TV Effects Presets that comes with AE. You can modify or edit these as you like.
I know of no specific style name that goes along with any part of this video other than lazy. It looks like nobody had an idea of what they wanted to do so they just shot a bunch of stuff and threw every effect they had in their bag of tricks at the project. Turn off the sound and it's impossible to tell what it is about. I don't mean to be critical but there's not much original here that I haven't seen a zillion times going back to the Video Toaster days. (probably before you were born). It's nothing more than a bunch of quick cuts and jitter.
Load up about 100 layers, trim them do different lengths from 5 to 30 frames, Select half of them, apply Bad TV1 to that bunch, Apply Bad TV2 to the another 10 random layers. Add tint, bulge, to a few more. set a couple of position and rotate keyframes to a few more then add wiggle to those, then use the Keyframe Assistant to sequence the layers and you'll be pretty close. It should take you about 15 minutes.
If you've got a specific question about how they made this jitter or how they made time stutter ask away. If used to tell a story these techniques are all useful. If you just want to create a jarring montage then follow my suggestion in the previous paragraph then run Brainstorm a couple of times. -
When using compressor voice is not sync with video. What causes this and how to fix it, please?
Although you say you have let the battery drain, was it for long enough? Since nothing else that you've tried so far has worked, I suggest that you leave the iPod unplugged for at least four days, preferably a week. That way, if something is stopping the iPod from turning the screen on, then whatever it is will drain the battrey. However, since the screen isn't on, that may take longer than if the screen was on.
Then, after that time, plug the iPod into a power source and leave it alone for at least thirty minutes. Only after thirty minutes will it show any signs of life, but you should leave it until it is fully charged before trying to use it.
If you get to this stage, the fact that the battery has drained will cause the iPod to reset when it springs back to life.
Let us know how you get on. -
Is anyone else having this problem and how to fix it?
There are no preferences for Quicktime 10, only for QT 7.
Mac OS X 10.6 includes QuickTime versions 10.0 and 7.6.3. The QuickTime 7 player will only be present if a QuickTime Pro key was present at the time of installation, or if specified as part of a custom install, or individually downloaded:
http://support.apple.com/kb/dl923
Snow Leopard update 10.6.4 included an update to 7.6.6 (if installed). You can install it from the above link even though it says for 10.6.3. It's the same version of QuickTime Player 7.6.6.
(Only QuickTime Player 7.6.3 or 7.6.6 can be updated to "Pro".)
For anything like Flash videos you should use QT 7. -
What causes TV screen to freeze but sound continue on TV when using Air Play from I Phone 4?
First try rebooting ATV and router. Beyond that, it's probably something within the network, typically interference.
To get a report of the network go to istumbler (Mac) or netstumbler (PC). Look for signal strength and noise.
If on wifi try ethernet. -

Unless you want a new computer, forget about AVCHD. It requires too much muscle to edit comfortably on anything but the fastest computer.
What camera is nice, depends on your budget. Formats that are easy to edit are HDV, DVCProHD (P2) and XDCAM. In the consumer range you could look at the Canon HV40 or XH-A1s, in the prosumer range look at the Panasonic AG-HPX170, Canon XH-H1s, JVC GY-ND250 or Sony HVR Z5 or Z7 and all Sony XDCAM cameras, especially the EX1 and EX3. In the professional range look at the Sony PDW-F355 or upward. -
What is the best way to export a video for broadcast using FCE? H264?
I need to get the best quality HD video for broadcast using final cut express and I need to know all info and settings please?
Hello,
You need to find out from the broadcaster what specs they require you to meet. H.264 is probably not it. -
Every once in awhile while using safari my bookmarks list disappears. Later it just shows up again. Anyone know what causes this and how to fix it?
I have had exactly the same problem now with two mini iPads. Everything was tried; 1) restarting; 2) restoring factory settings etc. NONE worked. Eventually Apple agreed to replace it. I have had the replacement now for two to three months and exactly the same thing is happening again. So off to Apple tomorrow to get another replacement.
I am quite a heavy user of the iPad so wonder if this is something to do with the fault.
It is so frustrating as sometimes reset works, and then after 10/20/30/40 minutes (you pick) it goes unstable again. -
