Audio plays but video does not........HDV

I have quicktime clips on my Macbook that are HDV 1080i format. When I try and play them in quicktime just the audio plays.....no video. Now I also have an iMac G5 desktop and quicktime plays these clips without problem. When I try to play them from my macbook a box pops up and says some components may be missing and it directs me to this web page:
http://www.apple.com/quicktime/resources/components.html
From here I don't know what to download in order to make it play my HDV clips.
please help. Thank you very much

AIC is required to view High Definition video on the Mac OS and it should already be installed on your machine.
Open the file using QuickTime Player. Open the Movie Info window (Command-i) and report back what it shows for the video codec.
You can test HD playback of known "good" files by viewing any of the HD trailers from this link: http://www.apple.com/trailers/
If they work as they should then the problem is with your HD file and not your computer.

Audio plays but Video stays stuck on a frame

I use FCP7. The media is a .mov, Frame Size: 720 x 405, Frame Rate 23.98, Pixel Ratio Square, Compressor AppleProRes 422, 48 kHz at 16bit, converted through MPEG Streamclip from an H264 file made from a DVD.
All I'm trying to do is cut off the first 2min of the file: Color Bars, Countdown Leader and Slate.
I Restarted FCP: that brought on the Video which was not there before. But now the video stays motionless. Anybody knows a solution? A thousand thanks.

Take a look at the chart near the top of this page: https://documentation.apple.com/en/motion/usermanual/index.html#chapter=B%26sect ion=5%26tasks=true
720 x 405 isn't one of the listed pixel dimensions. I'd recommend that you re-convert the original h.264 video file(s) to the proper dimensions.

Quicktime Movies - The audio plays but the video is completely messed up

Hi.
I have QuickTime V7.2 and my OS is XP.
All of a sudden QuickTime started playing back QuickTime movies with no video - there is just a lot of flickering green and purple - however the audio is there. Oddly, the files used to play fine. They were made on my PC as QuickTime movie files. The sound is there. (Additionally the files play ok in Realplayer.)
I've searched techy support but can't find an answer. Any ideas what is wrong?
I made the files on movie editing software called ULead, and as I said, they used to play fine.
Thanks very much.
Gary

A very similar and, I suspect, related problem. I created .mov files on my Mac, they play fine on the Mac, the audio plays but flickering video on my PC. I suspect it has something to do with the codecs used. Anyone have an idea as to how to make them compatible?

Audio plays but not video on abc app?

audio plays but not video on abc app?

Correct. The developers have not enabled it for airplay. Audio is on by default.

If the website does not allow downloading you cannot download the song. Or the website might have a special URL for downloading the song. For example, you watch videos at YouTube.com bu to download them you need to go to kissYouTube.com or saveYouTube.com

Quicktime Audio plays - no video

Have a site (www.myefa.org) that is used by MANY worldwide to learn English. The site has been active for quite a few years and has streaming video. We use Quicktime exclusively and are rethinking that decision.
After the 7.1 and higher upgrades the site's video no longer works. We have CDs to use with the site (also containing video) that do not work anymore either. The audio plays the video does not.
We have our users "downgrading" to 6.5.2 and explain that iTunes won't work. They must choose and aren't too happy about it.
The site listed above is used in school lab settings and by individuals. Many support persons (including moi) have attempted "fixing" the problem to no avail. We have performed all Troubleshooting tips given on Apple's site along with tips given in this forum...nothing seems to work, including installing 3rd party codecs.
ANY help would be greatly appreciated. If you go to the site www.myefa.org, click on Visitor, then an episode. Choose any camera icon to see video...chances are pretty good you'll hear audio but see white video.
If you do get audio and video please forward your settings to [email protected]
Thanks in advance for any assist.

Well, you've given us something to ponder. Thanks for that.
I also retried the CD's we have for the site (same video taken from the CD instead of streaming after clicking on the link) and get the following:
- the plugin was found, but an error in the plugin occurred.
- The plugin did not initialize properly.
From the Apple/Quicktime site the message is a wee bit different:
- An error occurred inside the plug-in on this page. (interesting that plugin is hyphenated here).
Again, all help is welcome and I appreciate your response.

Can't play Foxnews videos. Trying to use latest Firefox, Flash and Javascript is enabled. Ad plays but video hangs. Anyone else having this issue?

Have tried both Mozilla 12 and 16, have reloaded Flash several times, have enabled Javascript. Ad seems to play but video does not, only seems to occur with Foxnews.

You can check the Flash status [http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html here]. If you have any external Windows ad blocking applications, or if you're using a proxy you can try to adjust the settings.
Additionally, the Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Problem: Audio from the video plays, but video does not show.

Hi,
I used the following code to play the video. The audio from the video plays displaying the player but there is no visual.
There is no problem with the video as I have tried several other videos with .mpg and .mov extensions.
import javax.swing.*;
import java.awt.*;
import javax.media.*;
import java.awt.event.*;
import java.net.*;
public class MediaPanel {
    JFrame frame = new JFrame("Movie Player");
    static Player player = null;
    public MediaPanel(){
        try{ // method using URL
            URL url=new URL("file",null,"c:\\temp\\A.mpg");
            player = Manager.createRealizedPlayer(url);
        } catch( Exception e) {
            System.out.println(" Unable to create the audioPlayer :" + e );
        Component control = player.getControlPanelComponent();
        frame.getContentPane().add( control, BorderLayout.CENTER);
        frame.addWindowListener( new WindowAdapter() {
            public void windowClosing(WindowEvent we) {
                MediaPanel.stop();
                System.exit(0);
        frame.pack();
        frame.setSize( new Dimension(600,600) );
        frame.setVisible(true);
        player.start();
    public static void stop(){
        player.stop();
        player.close();
    public static void main( String args[]){
        MediaPanel panel = new MediaPanel();
}

use this code "Component control = player.getVisualComponent(); "
instead of this code " Component control = player.getControlPanelComponent();"
But if you want show both of them, modify as following
Component control1 = player.getControlPanelComponent();
Component control2 = player.getVisualComponent();
then add the two control (control1 & control2 ) to your JFrame panel

Exporting video for iPod - audio OK but video is "white"

I know this issue has been raised before but I cannot find a clear resolution anywhere - happy to be pointed to the right place.
Some time ago I converted some old VHS home movies to DVD and they play fine. To view them via AppleTV I've converted them to MP4 using H.264/AAC via MEGUI, and they work fine in iTunes on the PC and on AppleTV.
Once they were in iTunes I tried converting them for iPod but the output is a blank white video screen though the audio is fine.
To diagnose the problem I tried loading the MP4 version directly into Quicktime (Version 7.6.8)where the play fine. Then I tried exporting them for iPod and I get the same white screen plus audio.
I've seen this issue dismissed as due to some form of DRM but I doubt that is the case here. The video is my own, the DVDs I created are not CSS protected and the MP4s are also unprotected.
I've also seen it attributed to a missing codec, but that is unlikely given both iTunes and Quicktime play the videos without a hitch.
Any clues on how to proceed?
John

Last post before I leave things alone for a while.
I've uninstalled and reinstalled iTunes and Quicktime and iTunes no longer chews up lots of CPU when trying to convert one particular Quicktime created file.
I've also recreated each file again from the same source, the AVI encoded as DV-PAL with screen res of 720x576. I created a series of test cases to try to pin the problem down and I think the best exposition is the following -
The problem
An MPEG4 file exported from Quicktime loads and plays in iTunes, plays on AppleTV and can be converted for iPod.
An almost identical MPEG4 file created by MEGUI using the x264 encoder, latest build 1649, and all the same settings as Quicktime loads and plays in iTunes, plays on AppleTV but when converted for iPod produces a file with audio but the video is "white". Looking at the file size, less than 2mb, it is pretty obvious that the video stream is simply not there.
Clues
Quicktime Movie Inspector reports the screen resolution of the file it exported as 720x540 while for the MEGUI created file it reports a very odd 787x576. Note that Windows Media Player and YAMB (MP4Box utility) both report this same file as 720x576 which is what I would expect as MEGUI did not resize the video. As an aside, WMP and YAMB also report the Quicktime created file as 720x540 so they agree with Quicktime on that score at least.
Obvious Question
Why does Quicktime report an incorrect screen resolution, and is this contributing to the conversion problem in iTunes?
My understanding is that MPEG4 uses 16x16 macroblocks and so the dimensions of anything to be encoded must be in multiples of 16 and 787 is not a multiple of 16.
Of course, the 787x576 screen resolution could be a red herring.
Details from Quicktime Movie Inspector follow:

Audio plays, but no video on all projects & events

I am running iMovie '09 & I have imported video from my DV camcorder. in the event library, I see the frame thumbnails, but if I move the mouse over them, they turn black & when I mouse off it, the picture comes back. If I hit play on an event or a project, all I get is a black screen, but the audio is perfect. It's almost as if iMovie left the lens cap on!
What could be causing this? I can provide screen caps if that would be helpful at all.

HELP!!!!
I have a similar problem. I'd finished a project, used the transition editor to get rid of an "um" and now the entire video part won't play -- audio only.
If I could revert to the original version, I could live with the stupid UM, but I can't even figure out how to get to there.
PLEASE HELP!!!! I DON'T WANT TO HAVE TO EDIT FOUR HOURS WORTH OF WORK ALL OVER AGAIN FOR A STUPID FREAKING UM!!!!!

Audio plays but the video does not

I'm using the latest FCP and I've imported .Mov files which I've run through compressor so they all have H.264 at the end, however when I play them, the video stays still; only when I pause it does it jump ahead. The audio runs fine.
Am I supposed to run this through Compressor again (ie. I did it wrong)? Or is it just a settings thing?

I have a Flip and that takes video in .MP4; when I brought that into FCP it had a similar scenario play out so I assumed that I was supposed to have it as .MOV so I went to compressor to do that. I don't use Compressor often (read: ever) and I selected the one thing that said quicktime which also said H.264.
Sorry, Tom, I really don't know the ins and outs of this stuff.

Audio plays, but no video

I watch a live service online and it was working just fine. Then I went to watch it and I could hear the audio, but not see the video. It just shows a black screen, yet I can hear it. I updated flash player and I can see the flash video thing on the website and it says flash player installed. The live video is using Flowplayer and I have Mac OSX. I downloaded the correct flash player for Mac OSX too.

Yes, disabling hardware accelaration I have no problem with flash player.
