• Adobe Presenter video Express: problem with webcam Logitech c920

  Hello

  I have a problem with Adobe Presenter Video Express, when I want to use the camera Logitech c920. (computer laptop Dell Vostro 3560, Windows 7-64 bit, 8 GB of RAM, memory)

  When I launch the program and start creating the new project, I see only a black screen with the error message "your webcam is busy or it does not." "Try closing other applications that might be using the webcam and select it again. But when I press "record", program begins to make the video - and the webcam works. My problem is that I can't use video effects to change the background: I can't see Preview video/webcam with button "make my impressive background." When I switch to the integrated webcam, it works without problems, including the function of substantive change.

  I have closed all other programs. I restarted the laptop. I deleted and reinstalled the drivers for the camera. But it still does not work properly.

  Any suggestions how to solve the problem?

  Thank you

  Hi George,.

  In our tests, we saw that the Logitech C920, must the last driver of Logitech and the software must be installed so that it works correctly. Please make sure that you are picking the latest driver from the following link:

  http://support.Logitech.com/product/HD-Pro-webcam-C920#download

  If installing this driver does not resolve this issue, then please try the following:

  1. Sometimes, the webcam is busy on the launch of the app. Select the camera, then the Logitech camera to try a fix for this problem.
  2. Some Bluetooth drivers interfere with the functioning of the app. Disable all Bluetooth devices and see if it solves the problem.
  3. Send us a journal of diagnosis of the problem. You can follow the steps in this link to launch the application in diagnostic mode: presenter help | Adobe Presenter Video Express (Windows & Mac) . When you close the application, you will need to send us the diagnostic log. Please send it to [email protected] . A journal of diagnosis can help us to quickly solve the problem.

  If the problem is not resolved, can we get a Connect session to debug the issue? You can contact us at [email protected] with a suitable date and time, and we will solve it through Connect. We are available Monday - Friday, 18:30 - 11:30 PST.

• Logitech c920 no video display Webcam in Firefox

  Does not show my Logitech c920 webcam video in Firefox, but the audio works fine.

  I have tried with all disabled add-ons.

  It is the only webcam on my system.

  I found a fix for the problem. For Firefox, in his topic: config controls carried out in accordance with the preferences media.*.enabled media.autoplay.enabled search is set to false. Return to the default Boolean value (true) solves the problem. A response to this thread also proposed changes to the preferences of media.*.enabled back to their default settings, but it does not apply to my solution. Therefore, other media.*.enabled preferences are not relevant.

• Logitech C920 sequences is more than double the size of the original file

  Hi all

  I'm very new to adobe Premier Pro and I am just a little overwhelmed by the software. Here is my configuration of curect.

  Webcam: Logitech C920

  MIC: Blue Yeti

  I record video using OBS and it generates a file in the MP4 format. About a 10-minute film is at most 200 MB. Now, when I go to edit the clip in Premier Pro I understand that I must first begin a new sequence. This is my first problem: there is no predefined sequence that matches the C920 Locitech. So for now I'm just drag and drop the file into the time line. Is this correct?

  I can do the basic changes for now and that's fine, the problem comes when I go to export the images. I used H.264/Custom upstairs (MP4 format), I leave everything as it was. only 2 things I edit are the maximum and minimum flow for 10/16. I also check the box use overview at the bottom (I think that's what it was called) now when I hit Caryl export my PC Suite for about 10/15 minutes and give me a file that is about 700 MB in size. This is more than double the size of the original file. Why is this?

  If there is more information you need, I'll do my best to advise.

  Thank you

  If the C920 clip is the first clip you fall into an empty timeline, first expected to ask if you want to change sequence settings to match the clip (unless it is already). To be sure, simply right click on the clip in the project bin and select new sequence of the Clip and they will match for sure.

  The size of the exported video file is dictated by one thingand it is not frame size or frame rate - sampling rate is what determines the size of the file. If you want to halve the size of output file, you will need to reduce the flow rate by half.

  Rather than using Custom, maybe find a predefined existing H.264 which you gives the combination of quality and size of the file that you like? Make sure that the size of the image and the frame rate matches the source. How do you want to display or distribute material - on computer, on a device, online?

  I do not use the option use the previews - that means you take a temp make file and redisplay (transcoding) there again, adding a new generation of compression loss. By not checking this box, first visit the direct export from the source element format, by cutting out the middle man. I do not have a clip that is so effects loaded it will not play in the timeline panel to check the results, I don't bother making anything green. Everything is done at time of export anyway.

  Red, yellow and green make bars and what they mean. First work Pro area

  Thank you

• No video animation of character with logitech c920 10 x 64 windows

  For some reason, I have no video, but audio works somewhat with my hd pro c920 Logitech Web camera.

  All the drivers are up to date and the webcam works fine with other programs, including the Logitech Control Panel.

  If you temporary disable each capture device at a time (right click, then choose turn off), it is a specific device that is causing the problem? I just tried our Logitech C920 on a machine to win 10 and had no problems. I didn't install the app store, simply Win 10 to find the default driver for it. When I connect a second Logitech Web camera, he could see a (the most recent one I have attached).

• Infinity focusing problem on my SX700

  I always infinity focusing problems with my SX700.  I have the yellow box indicating that the image will be sweet if taken.  This happens on at least 1 other point cannon and shoot that I know.  I can focus to several hundred feet but not 10 000.  Does anyone else have this problem?  I am at my end and ready to jump ship to another manufacturer if I can't get to the bottom of this.  I never had this problem with my G-10.  Could this be a problem with extreme telephoto lens Canon point and shoot models?

  I have a Canon PowerShot SX150is and a Canon PowerShot G12, and I get the same questions. Here's what I learned. The problem with any long zoom point and shoot at the tele end is the amount of contrast detection that occurs to allow the development. With shorter zooms, the atmosphere is less dense, but more zooms to detect the density of the air. This is particularly noticeable on days with higher humidity levels, but would not have noticed the days of low humidity very dry. So the blur warning you get. The camera is not getting enough contrast to narrow the focus. No matter what brand you use, if the camera uses contrast detect focus, it will be the result. Not all use contrast detect, so be sure to check before you choose "deserting a ship."

  I would keep the ISO as low as possible, and if you can manually set the focus to infinity, it should help. But this has always been a sore spot with me on cameras Canon PowerShot with how long and complex manual focus is. Hope this helps you understand what may be the problem you are experiencing.

• Audio synchronization using Logitech C920

  Hello.

  I'm shooting in 720 p with my Logitech C920 sound is very much like raw file and in the windows movie maker even after saving.

  When I open it with first it is out of sync, before you create the track and after registration.  I'm new (using test), I am new to what all these crazy and my guess is that I screwed up something maybe. Everything worked very well the other day.

  I just used the settings by default when I prepare a new project. I save android H.264 720

  I've attached a screenshot of the file details if that helps. Thank you so much, I hope really that I can solve what I won't re - film or use another program (WMM sucks lol).

  

  Hi, I looked around for answers and I used handbrake to make CBR instead of VBR bitrate and it is fixed. However when I record with handbrake some quality is lost someone can you please tell me what settings to use for better quality that I have NO idea. Thank you very much!!

• Focus problems

  Hello
  
  I spent a lot of time trying to figure out what was causing a weird problem that is a few clicks away from buttons are ignored. After doing some tests I ran into components compiled Clip. If I remove them from the library that the update works as I expect. The problem is that I don't want (and don't have the time to) create or find replacements for all of the Compiled clips I used in this project.
  
  Does anyone know how to overcome this problem without removing these components?
  
  I've created a simple example to show you guys the problem we have here.
  
  If you compile the code and run the application (slider.fla and problemCompiledClip.fla), then click on in the textField (to set the focus to the subject), you will see the focus remains in the textField component when you click the buttons. I don't want this behavior, I would like the update in the... invisible buttons.
  
  Now, if you go to the library (on problemCompiledClip.fla) and delete component ProgressBar which is not yet used, the behaviour you will get is that I want to achieve. This is the average, even if the focus is in the textField and then you click any button, the object disappears from the textField object. Who do ALL the events of clicks in the buttons of her captured.
  
  If I wasn't clear on the problem, let me know.
  
  Thank you very much
  See you soon

  I use components if I am unable to get detailed help. but I know that this problem has been discussed in this forum and, I think, using the component development manager led to a resolution of the problem.

  Try this forum looking for something like focus problems. most of the people who encounter this problem do not realize it is a problem of component and if the components are not mentioned in their section of wire or a subtopic.

• window focus problems

  Hello fellow travelers... Since the update to 10.11.5 I have problems with windows does not come to the front when you click on to and does not come to be the focused window. No left or right mouse clicks don't work in the window. I have to close and reopen a window to make it sensitive. I also get error messages stating that the audio files cannot be changed because they are read-only. I read in the Infolog & right of authorization user and administrator. The files are on an external drive and were available in os 10.9.5. Any ideas?

  See if start-up aid.

  Stop your Mac. Start with the SHIFT key is pressed. This will start in Safe Mode, with all extensions turned off. Safe mode is slow to comlete, so give it time, he checks a lot of staff. If it works fine in Safe Mode, restart normally.

• Astrophotography Focus problem

  Hello I have the NEX 6 (with the SALT 50 mm F1.8 lens) and most of the time to enjoy. I bought it mainly for astrophotography and need tips for image correctly targeted (during playback or downloaded on my computer). I can't seem to get a clear focus, on the LCD or electronic viewfinder, but reading and uploaded images are not as well doors. I take several images focus, but no adjustment of the scope or the camera make attention the final result. This problem is the same in all forms of astrophotography, home, eyepiece projection and imaging of the camera.

  What camera modes are best for this Live View configuration effect i.e? I tried to use peki Focus, but is not effective for these low light objects like planets. Even the Moon images suffer from the same problem.

  I tried pre-focus the camera to infinity by placing it on a tripod or grafted onto the stand using MF Assist and the scope for a 'infinite '. THA has not helped either. I tried techniques, proposed on the astro sites, such as the use of high ISO focus, wearing different glasses (and set the diopter adjustment VIEWFINDER accordingly) and reset the ISO for the shhot. none available seems to help. What suggestions do you have?

  Thanks in advance for any assistance with this problem.

  I would recommend that you enable the setting [before Shutter curtain]. This function is intended to shorten the time lag between the shutter by reducing the movement of the shutter mechanism.

  Vibration caused by the shutter must be quite negligible not because of blur your images. Please check if the images taken with the Shutter curtain before setting enabled and disabled will have any differences. If the subject (e.g. stars) move, slight blurring occurs when you use a slow shutter speed.

• random auto focus problem Canon EF-S 18-55

  Hello

  I have worked with Canon EF-S 18-55 IS NO Lenes and have found a problem that I just can't seen to solve. The problem is I get autofocus, but at times it will not focus. I changed the card with a known good, engine Assembly, contacts with good looking for work units but not the contact Strip because they seem good.

  The Assembly moves freely with little resistance. I've also seen this problem on the IS versions too but especially on versions IS.

  I'm looking for any other suggestions that could solve the problem.

  Well I finally found out what the problem was and fixed 3 Lenes.

• Focus problems with Rebel T3i. It will not be in manual or auto focus point. It's not about camera lens

  My camera will not focus. Not only the autofocus. I can't he focus even if I put manual focus.

  The image is still blurry.

  First I thought it was the lens I had but I tried with several, and the problem is the same.

  Any ideas what could be the problem?

  Thank you

  Have you checked the viewfinder diopter?  , It will be not clear even on the manual focus, and it happens with all your lenses makes me think that it is possible that the dial tiny bit right there on the eyepiece was implemented accidental market. The dial control what you see in the viewfinder, not something to do with the focus lens. The diopter is adjustable so that those who need glasses can see things through the viewfinder.  If everything still seems blurry even when the camera thinks he's focused it is generally just that little diopter got hit accidentally.

  IFIT is not this, then perhaps your screen focus got shifted.

• List of the HorizontalFieldManager with scrolling focus problem

  Hello

  I'm doing a vertical list of horizontalfieldmanager with an icon and two text fields, but I'm having a problem when scrolling it. I used a nullField to manage focus. When I scroll to the top everything works well, but when I Ahmed to the bottom of the item appears on the edge of the screen.

  I guess that I did not understand how to manage the focusChange metodh and the metodh of the painting.

  All advice will be appreciated.

  Then try to create your NullField with getFocusRect override: like this:

  nullField = new NullField(NullField.FOCUSABLE) {
    public void getFocusRect(XYRect rect) {
      getManager.getExtent(rect);
      rect.setLocation(0, 0);
    }
  };
  

  Paint won't help you - you must tell the system to the entire span developed in order to scroll properly. If the above fails, analyze your focusChanged eventType and make sure that your Manager is fully visible on the screen on FOCUS_GAINED. To do this, you need to use getManager () .getVerticalScroll () / getManager () .setVerticalScroll () as well as of your Manager and getHeight() getTop().

• Custom bitmap focus problem with toolbar

  Hi all

  I'm new development of BB.

  I have screen with the title bar and after a toolbar customized

  The custom toolbar contains 3 bitmaps in the side chain and the left text right.

  Logo 'text'---> title bar

  Image1 image2, image3 "screenName"---> toolbar custom

  ListField

  Three images are created using the bitmap.

  I get the focus on the full range.

  But I want to focus on the first image, image1 when the application runs.

  If the user navigates the screen using the keyboard, change of focus to the next image, which is image2 and so on.

  How can I do that.

  I use the Blackberry API 4.2.1

  Please help me to solve my problem.

  Remember that the BlackBerry smartphone focuses on a field, not a picture.  Your toolbar is only a field, so one thing to focus on which is the Blackberry's.

  You have two choices:

  (a) change your toolbar to be a Manager and have several fields that it contains.  You can make a HorizontalFieldManager and assuming that the other things are set correctly (in particular the width of the fields that you add) this will do what you want.

  (b) substitute events in development movement in your toolbar to make it appear focus is moved.

  I think the second option is more difficult, especially when you start to take the touch screen into consideration.  However, with the second option, you get a much easier control over the look of your toolbar.  But I'd go with the first one, as I think it is easier for new programmers.  Initially, I wouldn't get to hung up on the appearance of the toolbar, get it works the way you want and then try to get it looking right.

• Field Focusable problem

  Hi all

  In my program, there is 1 HorizontalFieldManager and 2 AbsoluteFieldManager

  Now, I add 2 AFM of HFM and it looks like this

  __ ___ __ ___ __ __

  |    AFB1 |    AFM2 |

  ----------------------------

  the problem is when I add a buttonField, ButtonField.Focusable in AFM2

  When the application is run, the starting point should not be the AFB1 but it's my buttonField

  I think that happens because of the buttonfield Focusable

  If anyone knows how to fix this help please me, all I want is to ensure that the application starting point will be to first vfm.

  Thank you

  on the screen display, the first Focus field gets focus.
  There are no fields in AFB1, how to get the focus?

  You can put a nullfield in this, or any other field focusable.
