Continuing import problem with USB cameras.

In other threads people have discussed problems they are having with iMovie 7.1.1 in importing with USB cameras. I have had the same experience with my Sony CX-7 on two different MacBook Pros including a brand new one. Once in a while the camera will trigger the import page but usually not. Is this a bug Apple is aware of and working on?? Other suggestions for a fix or work around. Very frustrating.

Hmmm... I think there might be some sort of bug with the app regarding USB port connections. iMovie wouldn't even launch for me until I disconnected my 2 external drives. However, it seems that when I mount the external HD that's connected via firewire, iMovie is able to launch. But when it's the other external drive that's connected via USB that's mounted, that's when iMovie won't even open... And the weirdest thing is that, when the external HD that's mounted via USB is connected, just as you think the app has launched correctly, it sort of brings up an error message box that I can't even read for it just crashes immediately...

When I make a video with the camera ipad mini seen but not heard I can do ?

Yeah, of course you can. All you do is, open PhotoBooth, record your video and then, once you have stopped the video recording just drag the movie out of the bottom of PhotoBooth onto the desktop. It is in .mov format so you can then add it to iMovie for further editing or just upload it to youTube as it is.
Easy as pie!

How do you record video with usb mic and have the audio from garageband be the sound when recording and not just your normal voice but garage band effects for youtube?

How do you record video with usb mic and have the audio form garageband be apart of the video when recording, meaning the audio from garageband and echo and not just your normal voice for youtube post?its not add the garageband audio its just normal voice from mic no effects is going thru?

Hi Life93,
What you describe would be possible by recording your video, then removing the audio from it and adding audio from GarageBand once the video is in iMovie (I presume here that you are using iMovie for your video production. Other applications may need different methods.)
See this thread on how to remove the audio from a clip in iMovie -

How to control and display video from IP camera using ActiveX control over Internet.

Hello,
I need to control my IP cameras over the internet. I need to log into the cameras and then display the video. There's an ActiveX control registered on the computer and works fine with IE to access and control the cameras. Controlling the cameras using IE works fairly well, but there are some quirks that I'd like to eliminate by using my own custom code.
Has anyone created a vi that controls a Foscam FI8905W over the Internet? I’ve attempted, but I keep getting a catastrophic failure when I try to call ManagementConnect Method in the DVM_IPCam2 ActiveX Control Module V1.0. I'm not sure whether I need to establish an IP connection with the cameras first, or allow the ActiveX control to establish it for me.
Some example code would be greatly appreciated. Running LabVIEW 2011 on a Win7 32bit. Even some code used to control a similar device using ActiveX over Internet would be helpful.

I have an example vi for interfacing to the foscam activex.
I plan on using mouse click events within the activex window to trigger the PT function.
I only have the basic up/down/right/left directions and not the down-right/down-left/up-right/up-left in the enum. You can load the camera's web page and view the source to see the Java script code that uses the activex control. There are definitions for the other directions.
I had to mark the control as "Disabled" to keep click events from going to the activex control. If I double click the control, it goes full screen. If I then click on it to get out of full screen mode the video never returns or returns to the wrong spot in the VI.

X300 with Distorted Video With USB Port Replicator

I have 2 X300s using the enhanced port replicators. The video on these two machines were fine for the last 2 months until last week. The video is distorted while connected to the VGA port on the replicator, but fine when connected to the onboard video. I replaced the port replicators and that seem to resolve the issue for day but the distorted video came back. Has anyone encountered this and is there fix? Both machines are on XP.

Hello Rudi,
Thank you so much for the reply.
We tried today another T440 laptop with 64bit OS and as mentioned by you, we figured out that the conflict is happening between Intel Graphics 4400 driver with USB replicator.
When I done an uninstallation of the updated Intel Graphics and the USB replicator works fine.
As the laptop will be provided to HOD, so we will be going for a purchase of a replicator with good compatibility with 64 OS and intel video card.
Appreciate your reply.
Good day ahead.

IMAQdx change fps adquiring with USB camera

Hello,
Im working with Labview to process images captured with an USB camera. I would like to know how to change the adquiring conditions of the camera, in special the frame rate per second (fps), the video mode and the resolution. I need to change this parameters in real time, while the program is running.
Thank you.
Solved!
Go to Solution.

Hello again!
I have yet not found a single camera where the frame rate was not changable. Maybe you need to change the video mode.
I have created some snippets for you to play with (attached). Drag and drop the images to a vi block diagram to copy the code (You might have to save the images to disk first).
Best regards

My new iphone 4 does not have any sound when recording a video with the camera app. Does anyone know how to fix this?

I just got a new white iphone 4. When I try to take a video using the camera app, there is only a muffled sound. I never had this problem with my old iphone. I tried to restore it and that didn't help. I checked over all of the settings. Does anyone know how to fix this?? Thanks for any help you can offer!

There is a good possibility that your trimming of the SIM card could have damaged it some way. If the SIM was working in the old phone, then you cut it and the first new phone didn't work and now this phone doesn't work, it leads me to believe it has to do with the SIM card or the account. You are sure there is no problem with the account. Did you check with the provider when you got the iPhone 4 to make sure there was no problem with the account when you could not send or receive SMS? Why can't you just get a micro-sim? The iPhone should have come with one when you purchased it.The iPhone 4 is designed for a micro-sim. I don't believe this is a hardware problem unless the phone has been hacked or modified in some manner.

Taking a picture in LabVIEW with USB camera

Hello:
I am trying to find a way to use a Logitech USB camera (or potentially a different USB camera - perhaps a more expensive Edmund Optics camera) to snap a picture in LabVIEW. I have NI Vision software installed as well as the IMAQ USB extension for Vision, but I'm not sure where to go from here. All I need to be able to do is to snap a photo within LabVIEW and have LabVIEW save it onto the hard drive. Any help would be greatly appreciated.
Thanks,
Brad

Hi Brad,
Some of the information in the thread linked above may be out of date.
Check out this article [Acquiring Images in LabVIEW Using a USB or an IEEE1394 (FireWire) Camera] for some advice on how to snap your pictures. If you already have the NI-IMAQdx drivers, you should be able to use these for acquisition (as long as the USB camera is DirectShow compliant).
If you do not have the NI-IMAQdx drivers, but you do have the Vision Development Module you will be able to download the Vision Acquisition Software which includes these drivers. The vision acquisition software can be found here: http://www.ni.com/nisearch/app/main/p/bot/no/ap/tech/lang/en/pg/1/sn/catnav:du,n8:13.79.7820,ssnav:s...
I hope this helps!

24" cinema display. comes with USB cable?

i ordered the display and the web page says in the "what's in the box" section that it includes an AC power cord. does this mean i will have to purchase the USB/mini DIsplayport cable separately?

It has a permanently attached cable.

Why is Safari 5.1.7 for Windows the only browser that displays video with gray background, when it's white in four other browsers?

Hello all,
Here's my coding obstacle to overcome with Safari in my local dev environment using Windows 7 32-bit and wamp server. I created a pretty straightforward one and a half minute animation in Flash with a white background. Then I exported it as both an swf and avi video, then I encoded to several different file formats - ogg, mp4, and webm. Firefox 19, Chrome 24, and Opera 12 all play the webm file correctly showing the video's white background as expected, and IE 10 plays the mp4 correctly.
However, when Safari 5.1.7 plays one of these files that I can't distinguish (because right click functionality displays nothing), the video's background property is changed to (gray) throughout the video instead of white. What the?
Can someone please provide a workaround?

Yes, I am still having the automatic tab reloading and I am ******* sick of it.
I have lost count of how much work I have lost because of it.
I have 8 GB of perfect new RAM and tonnes of SSD HD space, I have tried reinstalling the OS etc and every fix on the internet (no (SP) mode does not work, nor does switching Java off etc, it's not an extension nor corrupted anything ... it's an uncontrollable fault with Safari).
Why does it keep happening !?!
And I am so sick of Apple not acknowledging this and responding to it.
What triggers it ... it is a built memory or cache limitation? It is a plain and simple crash?
How do I debug it to find out?
It strikes me that 20 years after the internet went public Apple ... despite all their billions and open source developers working for free ... still cannot make a browser that does not crash and so they decided to make a browser that *appears* not to crash ... except that it *does* ... only now the facade remains erect but everything else behind it crashes causing all tabs to reload, and videos and music start to play.
And there is no way to stop it doing so.
The most key app of our day and it is a POS.

PAL Videos with NTSC camera

I have problems capturing PAL video played with a Sony DCR-HC40 NTSC camera. Though I can follow the movie at the camera level, nothing in captured in the Premiere Pro 1.5 program. What is the correct setting in Premiere?

I am with Steve, on not knowing how one might be able to do what you want, other than converting from NTSC to PAL. However, with PrPro 1.5, I would post to the PrPro CS4 and Earlier Forum, as many folk there do both PAL and NTSC work, and might have some nifty tips for you.
Good luck,
Hunt

Display Videos with Automatic Disclaimer Page

Hello,
I created an asset library that would store user uploaded videos in my SharePoint site and on-click instead of just jumping right into the video I wanted to add a disclaimer page with my site's logo and then a button that the user will click that will acknowledge
that they read the disclaimer message and would like to go to the video.
Is there any kind of built in functionality to accomplish this or what would be the way to approach this functionality programmatically?
Thanks in advance for the help!

Hi,
As there is no such OOTB feature, we can achieve it via JavaScript programmatically.
Here is a similar thread with a solution for your reference:

Captures PAL video with NTSC camera using Premiere Pro 1.5

I try to capture (download) PAL videos from a Sony DCR-HC40 NTSC camera using Premiere Pro 1.5. I can see the movie (on the camera) but none is captured in Premiere. I did it before and it worked, but I forgot the appropriate setting within the Premiere program.
I would appreciate any suggestions. Muenkey

The latter is the problem. As I hit the capture button, the tape in the camera rolls, I can see (and hear) the PAL movie in the view finder and on the LCD screen of the camera, but the capture window stays black (though the frame counter works) and nothing is captured. (This is true whether I use an NTSC or PAL project set-up in Premiere). Again, I know there is a solution. I have done it before but forgot the necessary set-up steps in Premiere.

Creating a video with ipad camera

When opening the camera the video button can't be activated. I can find the setting to enable it.

Are you sliding the right side of the screen downward to highlight "video"? (Instead of trying to tap "video"?)
Or do you have Restrictions set for the camera? (Settings>General>Restrictions)
