Video Preview problems

When browsing iTunes store I am unable to preview videos - just get a blank screen.
Checked on all computers in the house and the same occurs. Tried from work with no problems!
Anyone got any ideas?
Tried turning off AV/AS and some firewall rules with no joy

There is a slightly newer 10.1.1 version of drivers available from Blackmagic:
http://www.blackmagicdesign.com/support
Thanks for posting the screenshot. This shows that After Effects does not see the Mercury Transmit plug-in for Blackmagic. You should verify whether the plug-in is present:
os drive/Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore/
The file will be named DeckLinkTransmit.bundle, or something similar.
If the file is present, try uninstalling and reinstalling the (latest version of) Blackmagic drivers.
If After Effects still does not recognize the Blackmagic Mercury Transmit plug-in, open Premiere Pro CC 2014 and check Preferences > Playback, and whether or not video preview works there.

Weird video preview problem... frustrating!

Hi, I wonder if anyone else has had this problem... ?
I had a project that was working fine, but now I cannot watch a video preview by pressing enter or space. The timeline renders the preview then does nothing, just sits there. The play button in the program monitor changes to the stop symbol, just like it does when the video preview plays normally, but no video or audio is playing...
Please help!

ITunes store music video preview problem?

How do you get itunes to fully buffer music video previews from the store before playing them? They are very choppy and video is out of sync with the music even with a DSL connection.
In the past you could set a preference to do this.

iTunes 9.2 (61) and I'm getting a failure rate of 100%!
Strictly audio, and I also find it annoying that the pop-up appears at the bottom of my iTunes window off-center nearer the right side. When the video finishes buffering +(3 Mbit connection, too)+, the pop-up window moves to the center.
Pressing stop/closing the window, before it begins playing can wreak havoc. Sometimes the "stop" dialog will keep popping up after I press stop, or the pop-up window will move to a different position, or it's white background will render outside of the window, or I'll get multiple segmented overlapping pop-up windows...

Problems with video previews: image freezes when scrubbing (CS6)

I just installed CS6 on my computer after working with CS5.5 and I encountered a strange problem with my EOS5D Mk 2 and also Ixus 100IS footage in Bridge CS6 (actually this happens with every video).
In CS5.5 I was able to preview my mov files and scrub through them without many problems (aside from a casual crash, but hey... )
In CS6 now the video preview starts and everything seems fine, until I scrub to a later point in the video. At that point the video freezes but the sound goes on. The only way to make the video run again is to click pause and then click play again. You can imagine that scrubbing through videos isn't much fun..
Has anyone ever had a problem like that with CS6?
Since CS5.5 is still installed, I checked and found out, that in Bridge CS5.5 everything is still working fine: No video freezes there - only in CS6
I already updated to the latest graphics card driver and all updates from CS6. Does anyone have an idea what I could do?
some stats about my computer:
win7 64bit
nvidia geforce GTX 590, driver 301.42
no other video software installed
Aside from that, I also realized that video quality in the preview area isn't particularly brilliant (neither in CS5.5 nor in CS6). Since the video is scaled to the preview window size, I sometimes get scaling artefacts/moirees. Is there a way to smooth the video playback, like you could in a regular video player?

Perhaps your understanding of rendering is different than mine. I think of it more as combining edits to form a new video. Are you using rendering as the same as playback? Also, not sure how you can have a system that has only CS6 files, as files are the same for CS5.5. I must be missing something here.
Manniac described the error well "In CS6 now the video preview starts and everything seems fine, until I scrub to a later point in the video. At that point the video freezes but the sound goes on. The only way to make the video run again is to click pause and then click play again".
Believe that error is fixed as my video play OK now.

How to tell whether video preview is working?

An app shows video preview with code essentially the same as in
the MSDN document:
async void ShowPreview(object sender, RoutedEventArgs e)
if (mediaCaptureMgr == null)
// Using Windows.Media.Capture.MediaCapture APIs
// to stream from webcam
mediaCaptureMgr = new MediaCapture();
await mediaCaptureMgr.InitializeAsync();
myCaptureElement.Source = mediaCaptureMgr;
await mediaCaptureMgr.StartPreviewAsync();
It works most of the time. However, sometimes the video does not show. When this happens, myCaptureElement.ActualWidth and myCaptureElement.ActualHeight still return the correct values. This probably means at least something is working. In this case, how can
the code tell what my eyes can see - the video is not showing?
Hong

Hi Hong,
Based on my knowledge, your problem may related to the dispose of the MediaCapture object. Forget to dispose it when app suspends will result in a negative user experience for your app.
About your question, I’ve not seen such property in MediaCapture class, so it’s recommend to create a Boolean that indicate whether the app is currently previewing video. You need to maintain this object when start or stop preview. You can find more information
from this page.

Video Preview not Working in CS6

Before AE CS6, I was using AE CS 5.5 on my MacBook Pro (model 8,3) and I could always go to AE Preferences:Video Preview and choose my additional monitor for previewing. I was previewing my Stereo 3d comps perfectly on my 3D hdtv through a HDMI to Mini Display Port cable.
I now have a Mac Pro and AE CS6 and in that preference, the "Output Device" dropdown only lists Firewire and Computer Monitor Only. With my old setup, I could choose my TV and everything was great. But this new setup won't allow me to see or choose my TV.
Please help! Has anyone else had this problem? Has something in AE CS6 changed for external monitors? I can't tell if it is CS6 or the fact that I have a new Mac Pro and it's video card might be different...

That's a great lead. I realized that Final Cut Cut Studio 6 was on my laptop before but it is not on my new Mac Pro. FC Studio 6 includes a bunch of codecs as I recall. So I went to install it on my new Mac Pro and I got an error message that said my Mac cant install Power PC architecture (or something like that) and wouldnt let me install it. Any Idea how I can get those codecs without installing FC Pro 6?
PS: I tried AE CS6 on my TV and it worked like a charm. There were lots more option in the Video Preview Preference.

Video previews not working in iTunes

Hi all,
I've seen this posted a few different ways without any resolution to the problem so I thought I would give it a shot.
Video previews are not working properly for me. When in the iTunes Store and I click on a "View Trailer" for a movie or preview for a music video, a pop-up window appears in iTunes with a white background. The audio will kick in but the video never starts. I am using iTunes 9.2 (61).
Has anyone uncovered a solution to this?
Thanks!

Just to clean this unresolved issue up, seemingly the problem disappeared after upgrading to iTunes 9.2.1 (5).
Thanks!

Camera video preview - Random crashes and green screens

Hello everyone,
I am currently working on a Windows Phone 8.1 app and I need to preview video from the phone's back camera. For quite some time I've been struggling with random crashes and green screens. When these green screens appear, all camera apps become affected and
the device needs to be restarted. Occasionally the phone freezes and only recovers after battery removal. I test the app on my Lumia 620.
After some web search, I found references to the same problem by many users/developers of different apps. I'm really frustrated as I've tried many possible solutions with no avail.
Here is part of my code:
//in App.xaml.cs:
MediaCaptureInitializationSettings settings;
public static MediaCapture captureMgr;
public static bool UnableToInitializeCamera = false;
public async Task InitializeVideoCapture()
DeviceInformation backWebcam = await GetCameraDeviceInfoAsync(Windows.Devices.Enumeration.Panel.Back);
if(captureMgr!=null) captureMgr.Dispose();
captureMgr = new MediaCapture();
settings = new MediaCaptureInitializationSettings();
settings.StreamingCaptureMode = StreamingCaptureMode.Video;
settings.PhotoCaptureSource = PhotoCaptureSource.VideoPreview;
settings.AudioDeviceId = "";
if (backWebcam != null)
settings.VideoDeviceId = backWebcam.Id;
else
var _messageDialog = new MessageDialog("Back panel camera not found");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
try
await captureMgr.InitializeAsync(settings);
captureMgr.SetPreviewRotation(VideoRotation.Clockwise90Degrees);
UnableToInitializeCamera = false;
catch
UnableToInitializeCamera = true;
Debug.WriteLine("HANDLED EXCEPTION: camera could not be initialized");
var _messageDialog = new MessageDialog("Unable to initialize camera");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
protected override async void OnLaunched(LaunchActivatedEventArgs e)
//.... other app initialization code
await InitializeVideoCapture();
Window.Current.Activate();
private async void OnResuming(object sender, object e)
AppIsResuming = true;
FinishedCameraInitialize = false;
await Task.Delay(TimeSpan.FromSeconds(0.5));//this makes crashes less frequent
await InitializeVideoCapture();
FinishedCameraInitialize = true;
if(WasPreviewingCamera)
WasPreviewingCamera = false; //the following line allows time for SetupPage._captureElement to be assigned before video preview starts while (!SetupPage.CaptureElementSourceAssigned) await Task.Delay(TimeSpan.FromMilliseconds(1));
SetupPage.CaptureElementSourceAssigned = false;
try
Debug.WriteLine("trying to restart video preview");
await captureMgr.StartPreviewAsync();
SetupPage.PreviewingCamera = true;
catch
Debug.WriteLine("HANDLED EXCEPTION: unable to start previewing");
SetupPage.PreviewingCamera = false;
GC.Collect();
AppIsResuming = false;
private async void OnSuspending(object sender, SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
while (AppIsResuming) await Task.Delay(TimeSpan.FromMilliseconds(1));//prevents crash when app is suspended right after it is resumed
await CleanupCaptureResources();
TimeOfLastSuspend = DateTime.Now;
FinishedCameraInitialize = false;
GC.Collect();
deferral.Complete();
public async Task CleanupCaptureResources()
if (SetupPage.PreviewingCamera)
await captureMgr.StopPreviewAsync();
WasPreviewingCamera = true;
SetupPage.PreviewingCamera = false;
else WasPreviewingCamera = false;
if (captureMgr != null) captureMgr.Dispose();
//in SetupPage.xaml.cs
void OnSuspending(object sender, Windows.ApplicationModel.SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
_captureElement.Source = null;
CaptureElementSourceAssigned = false;
GC.Collect();
deferral.Complete();
private async void OnResuming(object sender, object e)
ProgressRing2.Visibility = Visibility.Visible;
ProgressRing2.IsActive = true;
while (!App.FinishedCameraInitialize) await Task.Delay(TimeSpan.FromMilliseconds(1));
App.FinishedCameraInitialize = false;
captureElement.Source = App.captureMgr;
CaptureElementSourceAssigned = true;
GC.Collect();
ProgressRing2.Visibility = Visibility.Collapsed;
ProgressRing2.IsActive = false;
Any help towards a solution will be greatly appreciated.
Thank you

I will also advice that you start by following the
Windows Store app sample.
Is this a Windows Phone app?
The crash/green screen only manifests itself when I suspend my app and switch to the default camera app (could be any other camera app perhaps). It happens roughly 1 out of 8 times. That's why I posted the suspension and resuming handlers, which I wrote
according to the msdn instructions.
I found
this page with a sample that demonstrates the MediaCapture API for Windows Phone. Some developers have reported problems similar as mine. Has Microsoft dealt with this issue?
I've spent quite a few weeks trying to investigate this problem, without actually knowing if it is my code that needs to be debugged. That's why I'm asking if other developers are facing similar problems.
Thank you
Edit: It seems that the crash/green screen can appear when suspending/switching to any app (regardless if it uses the camera or not). Also, all works fine when the app is running on the debugger.

Video Preview Error: Error Compiling movie. Unknown error.

Problem in Adobe Premiere Pro CC - Rendering movie prior to Exporting.
I have cleared all Temp and Cache files to make sure I have enough space for rendering (126GB free space), but I still get a Video Preview Error message when I try to Render or Export.
What should I be looking for in my movie settings to clear the "unknown error"?

05555...did you get this reconciled??? If so, what did you do....I have encountered the same window myself, today.

Firewire Output for Video Preview Intermittent

I'm experiencing a frustrating problem with After Effects these days.
We're producing some video to be projected, so to see what the final output will really look like, I'm doing video previews using FireWire so output goes directly to the projector.
It's been working great up until yesterday. Was working fine until I had to restart my Mac. Upon reboot, my the projector no longer gets any video output.
I've tried restarting numerous times, checked all connections, etc. Got it working again after several restarts, but after switching over to Photoshop momentarily, the video output once again disappeared.
Any suggestions on how to regain consistent Firewire output for Video Previews?
My setup:
After Effects CS6
Mac Pro
OSX Version 10.7.5
Firewire Output of my Mac's monitor is going to the Firewire Input on my Sony Media Converter
RCA Video out (Composite video) going to the projector's video input.
After Effects Video Preview preferences:
Output Device: FireWire
Output Mode: Apple FireWire NTSC

Thanks for your reply, Rick.
I finally figured it out... I had a background application running called iCam that monitors my security cameras. I had forgotten that it uses Firewire and was intermittently hogging the resources. Once I quit that application, everything was good once again.
Thanks for taking the time to respond, much appreciated!

Multiple Screens Disables Monitor Video Preview

I have noticed a new bug (for me anyway) that on my Mac Pro with two video cards I cannot load clips into the monitor and get a preview. I see the clip thumbnails in the timeline, but no video preview. I just tested this by unplugging my secondary displays and that resolved the issue. Haven't yet tested with the laptop using an external display.
I did just update to Mac OS 10.9 Mavericks, but I was seeing this behavior prior to that. Anyone else seeing this behavior?

Hi -
Thanks for your post and attention!!
I could reproduce your problem on a Mac Pro with two graphic cards. The video could playback in Timeline panel and could hear the audio, but could not see the thumbnail view in Monitor panel. I have opened a bug for this and our team are investigating it.
Thanks & Best regards,
Jenny

No video Preview During Capture

Here is the scoop:
Adobe Premeire CS5
Windows 7 64bit
Canon XL2
Capturing DV NOT HDV
Canon standard device control as there is no preset listed for the XL2
Video and audio actually captures fine. I can hear audio during capture but cannot see any video.
I know there is no video preview when capturing HDV but I am capturing DV.
Again this is CS5 NOT 5.5 so .dll fix is not an option
Thanks in advance.

FIXED!
Heres how it went:
Went to Device Manager and let windows look for an updated driver for my Graphics Card (Radeon HD 4200). Windows said the most current driver was installed. It was NOT the most current driver. I went out to ATI and got the most current driver, installed, reboot and OH JOY! I get video in the capture window during preview AND during capture (of DV)!
I also let windows (device manager) look for updated drivers for sound and it said the driver was the most current. Again, it was not. so the moral of the story is...Don't trust Device Manager on current driver versions.
Hope this will help some folks out there.
Side Note*
Most of us spend hours on forums looking for answers/fixes to particular problems. Most replies I see are either in the vein of "I have that problem too" or " try this, it worked in this OTHER version or try this OTHER software" etc. If you dont have an answer/fix for the problem, dont post.
ON the flip side of that, when posting a problem you want an answer to, Give all the pertinent information in your initial question. " Premiere crashes when I plug up my camera" does NOT suffice! What version of Premiere, what camera, what OS, What kind of connection, etc.

FCPX 10.0.3: no video preview, crash

Hi all,
I have just updated FCPX 10.0.2 to 10.0.3 and it is a disaster.
The video preview is not working anymore: when i try to view one video from my events and pass the mouse over one, i hear the video sound, the time progressing but nothing appears in the video preview. If i try to play it (using the play button), FCPX hangs. I have to kill it.
It is the same when i edit a project: no video preview at all. It is very strange.
I tried a new project, import new videos, trash the prefs, reinstall FCPX from scratch with no events no projects, even make the lion combo 10.7.3 update (I updated lion the day before)...
My FCPX is useless. Do you have any advice that may help me?
Is it possible to roll back to 10.0.2 version via the mac app store?
My config; MBP Mid2009 15" (GPU 9600MGT).
Regards,
Chris.

ANYONE???
FWIW, I seem to be having similar issues. Used 10.0.3 for the first time earlier today (under Snow Leopard, on an 8-core Mac Pro now with 24GB of RAM). Constantly losing video -- audio plays fine. Never seemed to have this problem in 10.0.2. (Lots of other problems, mind you -- just not this one.)
Found I can usually get video back by opening Playback Prefs and making a change (like switching between "use proxy media" and "use original/optimized"), then waiting 2-3 minutes while the orange bar which has now appeared over the ENTIRE timeline -- even though NO changes have been made to the timeline whatsoever -- slowly goes away.
One of the triggers for losing the video in my case seems to be letting the Timeline play through till past the end. And I say "past" the end, because there's now suddenly a weird 2-3 minute void after the final clip of video. No audio, no "gap clips", just a big stretch of nothing. I can't figure out how to get rid of it, and the fade out I'd applied long ago to the last video clip no longer works. When the playhead reaches that transition (or nears the end of the last video clip, even with the transition removed) the video just cuts to black. The audio then ends normally while the playhead just keeps going into this mysterious blank emptiness for almost 3 minutes -- at least that's how much extra black I get when I do an Export of the Project.
Naturally I've tried re-doing the end transition; and have of course made sure there is no media of any kind down at the end of timeline which might be causing this strange empty section. Even tried carefully selecting all the real clips on the Timeline and Copy/Pasting them into a whole new project. No difference. The gap at the end just reappears.
(Meantime, as others have reported, I also experienced loss of parameters on several simple titles in Projects created in 10.0.2 and updated/imported into 10.0.3. Likewise for the irrational re-re-re-re-re-re-re-re-re-re-re-re-rendering. Have not yet had time to test any of this on a newly-created 10.0.3 project, but I really do look forward to the day when the bulk of my work in FCP-X might actually involve editing, with the time spent in trouble-shooting and unpaid beta-testing perhaps reduced to just a few hours a week. A crazy idea, I know -- but I can still dream.)

Video preview during capture CS3

Video preview during capture is not working even though settings are at preview video and audio during capture.
The work around seems to be to go ahead record anyway (red button) then it works after I paste the captured audio onto the timeline.
When pasting it to the timeline the video appears. The video appears during subsequent captures. It seems like a bug in CS3. This was not a problem with PP 1.5
Thanks

A few more of
these details will help us help you.
