ISight - my video image is jerky

Hope someone can help.
1 to 1 video chat using iSight. I can connect with my friend also using iSight, and the audio is fine. The picture quality i receive from my friend is great, but the one he gets of me is very jerky. Even when i view my own image it still has a jerky picture (could be a very low fps rate, but not sure). This jerky picture only happens when i am online with him.
When i am offline, and test the image by opening up the application and clicking on the camera icon next to my name, i can see my image but its fine. No jerky picture and how it should be.
I've checking my actual upload speed which is about 224kbps, so should be okay to handle my video.
Running 10.4.4.
iSight firmware is 1.0.3.
iChat AV
Any hekp would be great as tearing my hair out trying to figure out what the problem is.
Thanks

Hi
My pal and I had the same problem my image was okay but his was jerky, to me and in his preview.
He was also on Skype. When he closed down the Skype the problem was cured.
It may be because you are using another facility that it taking up band width
Good luck

ISight Terrible Video Quality

I recently picked up an iSight camera for my 2012 model Mac Mini, which is running Mountain Lion. The quality of the video is terrible, and I'm wondering if this is just a case of this being an old product that's not up to today's standards, or if there's something I can do to improve it.
The video image refreshes at a rate of about once every 3 seconds, and the picture quality looks like something from video chat circa 1998. The only thing I found in the iSight manual about choppy video was to lower the MBPS if your internet connection is slow. I tested my internet speed this morning and it's at a perfectly acceptable 10.5 mbps. But nonetheless I tried every speed setting available on the Message video preferences and there was no change.
The iSight is connected to my firewire port via a 400/800 adapter, IEEE1394A 1394B.
Thank you.

Your old iSight may have problems. Here are the things I know you can try:
(0) Use good (bright) lighting and take your time while starting iSight tests.
(1) How to test external iSight to ensure it is functional.
Be sure to test on a different network and another Mac.
(2) Apple's How to Troubleshoot iSight. Be sure to test more than one Apple camera app
in more than one user account if your trouble continues.
(3) Apple's iSight Service FAQs includes info about where to get external iSight serviced.
(4) Try a different Firewire cable and / or adapter unless you know yours are good.

ISight producing mirror image in all apps

Whenever I use anything that displays the video captured by the iSight camera, the image is a mirror. I cannot find anything that would permit me to configure the camera to show the image it's actually capturing. Is there a way I can do this?

Welcome to Discussions, bjames.wi
Software controls your iSight. Many, but not all, software applications give mirror-image iSight views. Different apps work differently. Your Mac's Help in each application should give you more info on how each particular app works, but here are some suggestions for a few of the most common apps.
(1) iChat's picture-in-picture and Snapshot is "mirrored" by design.
We are so accustomed to seeing ourselves in the mirror that it looks strange the other way. Your movie clips and the view that your chat friends' see and are normal. Only video snapshots you make and your video preview are mirror-image.
(2) You can change individual snapshots made with either iChat or Photo Booth by opening the file with your Preview application and using the Preview > Tools > Flip Horizontal menu command.
Full-featured image editing software such as PhotoShop or PhotoShop Elements can also flip images that have already been saved.
(3) You can change future Photo Booth snapshots with the Photo Booth > Edit > Auto Flip New Photos menu choice.
More info is in Photo Booth > Help > Photo Booth Help. Search for Flipping a photo there.
(4) iMovie is different. Its preview window shows images right-way-around, as is the customary view for movie cameras.
(5) To flip saved video recordings, QuickTime Pro can do it easily. Use QT Pro's "Visual Settings" controls in the "Video Track" section of its "Movie Properties" menu command to flip, rotate, resize, and edit other properties of an already-recorded video.
If you do not have QT Pro, you can use iMovie 6 HD. Import the saved Photo Booth or iChat 4 video clip into iMovie and use iMovie's "Mirror" effect in Editing >Video FX to flip it.
The latest iMovie version, iMovie 8 (sometimes called iMovie '09 because it is part of iLife '09), can also flip already-saved video. I do not think that iMovie 7 (which was part of iLife '08) can flip videos.
(6) If you really want to change your iSight's image, you can add iGlasses 2 software.
(7) If you are into no-cost, imperfect, and unsophisticated work-arounds, one kludged alternative would be to position a mirror as best you can so you are making video of your image in the mirror.
(8) If you need more info, when you post back please let us know which application gives you trouble.

PPro CS4 - imported .mov file and video playback is jerky

Hi all.
I have imported a Quicktime .mov file into a standard sequence. The audio plays back fine but the video is very jerky.
I did an 'interpret footage' on the clip and see it's at a frame rate of 1.2480.
How can I get this file to play correctly in a PPro sequence at 29.97 FPS?
Help! My deadline is getting close.
Thanks.
Keith

Thanks Bill.
Here's what I could find... I hope it means more to you that to me!!! I see that the average frame rate is 13.58. If I interpret footage and use that rate, 30 second commercial plays in about 5 seconds.
Thanks for the help.

Live Cam Voice on HP DV8305 -- Video image very slow

I installed Live! Cam Voice on my HP DV8305 succussfully, it works, but the video image is very slow. it needs about 30sec to capture a frame, sometime just stucked. I changed the Display Adaptive Driver, used differrent USB IF, checked my CPU and Memery usage, my HD space, use differrent IM -- skype, MSN, .... Any one can help?

As further information, the issue seems to be with the exposure setting. When I turn auto exposure off, then set exposure down as low as it will go, the picture darkens, but the frame rate goes up. I don't have this problem with my Logitech QuickCam Orbit -- I'm not sure if the problem is with the firmware, or if the CMOS sensor in the Live! Cam Voice is just smaller.

Flash video image problem with newest nVidia driver

I've got a very weird display error since the last update. Basically, whenever I play flash video and afterwards close the browser (chromium), any purely black surfaces will display the full flash player image. The effect is only visible in the "first" window of a xmonad tab, that means if I cycle the window positions it will be in a different window. The others are not affected. When I restart X, I can see the flash video image flashing up shortly on the black screen. Restarting X fixes the issue. I cannot take any screenshot of the problem because the error is NOT visible on the screenshot. Therefore I suspect that some frame buffer used for the flash player is not getting cleared properly after exiting the browser, but it's really little more than a wild guess.
As there are multiple components involved, I'm at a loss of where this might be coming from. I hope someone might be able to shed some light on this situation. Please post here if you have the same problem or have any idea why this happens!
My setup:
-nvidia 260.19.36-2
-flashplugin 10.2.152.27-1
-chromium 9.0.597.94-1
-xmonad 0.9.2-1
-xmonad-contrib 0.9.2-1

if you asking about a bug reported on arch linux bugtracker, then you are doing it the wrong way.
flash and nvidia are closed source, we can't do anything. A better place is to submit bugs to nvidia and adobe.
Now i see that nvidia 270.26 was released. Maybe you want to check that out:

How to send files like audio,video,images and text via RMI..

Hi everyone,
As I am working under a project, my own, of creating a chat machine, I've thought to make it capable of doing everything that MSN or yahoo MSN can do. Till now I've just been able to send messages and some small icons as expressions. So, my next step will be making my progam able to send even other files like audio, video, images and text to the person on the other machine to whom I'm chatting. But as I don't have any idea on how to start doing it, I want anyone who think he/she can help me to give me the basic logic that is used to do so. I would very much appreciate it. I've used vectors to store the text messages which is visible to all the users using the chat program enabling them to see various messages in it.
thank you...
Jay

Hi,
Now, I got stuck because the code doesn't seem to work well. For large files with around 40 mb or more size couldn't be sent. I have constructed the code, just rough sketch, as follows:
** In the Server Implementation class I've used FileInputStream to read the contents of a file that is sent as an argument to the method.
** Similarly, in the client side I've used RandomAccessFile to save the received array of bytes.
public void sendFile(File f)
   ChatServer cs=(ChatServer)Naming.lookup("rmi://localhost/ChatServer");
   cs.readsAndStoreTheFileInTheServer(f); // In the Server Implementation the contents of the file is read and saved in an array of byte. later method is invoked by the client to get the array of the saved byte.
   cs.message("-Accept-"); // When a client receives this word then a JComponent with accept and cancel button will be constructed from where other clients can save/cancel the sent file.
}For small size files this code works well but for files more than 40 mb of size it is useless. I wonder if there's any other alternative.
regards,
Jay

Is it normal that a Mac Mini 1.6duo play back of HD 60 frame home video is shuddery / jerky ? is this just processor limits ?

Is it normal that a Mac Mini 1.6duo play back of HD 60 frame home video is shuddery / jerky ? is this just processor limits ?
I have a pansonic 14meg camera which shoots HD 1060 30 frame and 720 60 frame .
I have been using the 720 6 frame . Playback using on my camera is perfect , but when I download on to my Intel 1.6duo macmini play back is jerky ... is this just processor limitation or if Mini should be fine to play back (using Quicktime7) could it be file corruption / camera issue.
I think it is just my old computer probably starting to struggle !
Many thanks

Couple of things:
There is virtually no standardisation of video formats. The file suffix is if little use to use as, in the case of video, files are just containers for data streams encoded and decoded by Codecs. Pretty much every manufacturer has their own codecs for each and every camera. Put it this way: every Jpeg still is pretty much the same, as there is an agreed standard for that format. There is no such guarantee with avi, mov etc. That's why the model and format of the camera is important.
This model was released in 2012, and you're trying to read data from this using a QuickTime 7, which predates that by a few years. Oddly, Snow Leopard came with QuickTime X, so I'm not sure what you've done there.
iPhoto does not guarantee to import all video from all cameras. What cameras it does support are usually still cameras with a video add on. What you have is a camcorder and the correct app for importing and manipulating video from such a device is iMovie rather than iPhoto. It may be able to transcode it.

Hey Friends - Trying to improve my video image on Dish Anywhere

Hey Friends - First inquiry to this forum. I'm trying to improve my video image on Dish anywhere app to TV in my home in MI from CO. I installed the new AirPort Extreme 6 in both locations but it does not appear to have improved the quality. Can my old AirPort Extreme 4 be used as an antenna on the Dish receiver? I'm using Airplay on the TV and wonder if this is the best I can expect or if here is anything else I can do to improve video quality. Thanks for your help.

Streaming video, especially HD video over the Internet requires sufficient bandwidth for video quality. That would mean, in addition to having the proper bandwidth on each of the local networks in MI & CO, the Internet connection between locations must also be able to handle the streaming traffic.
Most consumer-grade Internet service offers far better download speeds than upload. However both will be required in this case.

Can I adjust the video image I receive when making a Skype call?

I have made my first Skype call and the video image I see on my computer is very dark and I am wondering if there is some way to make adjustments? Do I need to get some specific software for viewing? I don't really understand the whole thing but I sure would like to have a better quality image of the person I am speaking with.
I appreciate any help I can get! Thank you

There's nothing much you can do unless the person
you skype to turns on some lights over their computer.

This may depend on your chosen encoding options for the Mails (MIME vs. Base64 or similar) and/or the mails being reduced in size and sliced up server side. Apple (and Google) do stuff like recompressing images when viewing mails on mobile devices from an Apple ID or Gmail account... You have to turn it off in their web frontends....

Video image problem

Hi...A neighbor has a iMac G5 and has developed a video/image problem. The iMac boots up and sometimes shows an ok screen for a little time, sometimes not. What emerges is an array of digital black on white graphic line images (maybe I should upload a picture), but makes the screen virtually impossible to see what you want to view, thus rendering the computer useless.Any thoughts as to what this is, seems like a hardware vs, software issues, but can't say for sure. What might it be: video card, other hardware on or attached to the logic board..and mostly could it be repaired (by self or reasonable). Any and all thoughts or experience welcome as I've been no help to my good neighbor friend on this one:)..Rick

me 2 it's clear .. the new firm has poor quality than the original one...sadly .. my n93i now has quality like n70 help!!!!!!!!!!!!!!!!!!!!!

Preview window in premiere 10 will not show view video images

My Premiere 10 preview window will not show video images. There has been some on-line discussion that nVidia GeForce video card automatic updates is the problem and it has been suggested that I roll back to a previous card however the rollback button does not light up and can not be activated. Also I'm not sure that I'm using the correct settings for the preview window, what are the default settings?

I recommend that you try your question in premeire forum, so you have a better chance of getting an answer.

I'm downloading using RealPlayer But the video playback is jerky. The audio playback is OK.   Can anyone suggest a solution. Would upgrading to RealPlayer Plus be a good thing to do?

I'm downloading using RealPlayer But the video playback is jerky. The audio playback is OK.
Please can anyone suggest a solution.
PS Would upgrading to RealPlayer Plus help?

I can't understand how internet speeds can be the cause of the problem. My problem with a jerky playback is that I have already down loaded.   Could this be to do with my computer (I maybe able to persuade my wife that I need a new one). Earlier I was listening to a clip of the MJQ, downloaded from UTube, and although the sound was good the picture was not.
My computer is an iMac with an Intel Core 2 Duo with a processing speed of 2.8 Ghz. Does this information help?
