Audio+Video Issue in AE CS3

I'll start off with the Audio issue first, because i can't even get a signal at all yet.
I searched through some other threads and read some information and tried this:
1. Checked Audio Hardware, has correct soundcard settings.
2. Checked Auido Mapping, has correct settings.
In the top right corner there is a green audio DB meter, but when i import a movie and push play,
the movie will playback with no audio, and no movement in the green audio DB meter.
I pushed LL before playback, and i can see the actual soundwave as the movie plays back,
but still no audio.
The soundcard is a M-audio Firewire Solo, and works great with Adobe audition.
I even used "edit in adobe audition" through AE, and the sound came out fine in audition.
The video problem i am having, is after i installed AE CS3, on the first run it came up
with a message saying CS3 was not compatible with my video card, so it disabled some
setting, (which i could later turn on in preferences?) i don't remember what setting it was talking
about, but i believe it had something to do with OpenGL.
Either way, video playback does work, but when i try to put certain effects over the video,
it seems to run very sluggish.
The video card is a ATI Radeon HD4850.
My system us running XP sp3 with 2x2gb Ram.
thanks.

You have a misconfiguration of your graphics card driver. That card by all means should have enough juice to run with OpenGL. Try a newer one/ different one/ flip a few switches.

it seems to run very sluggish.
What effects and what source footage? Some effects are just slow and decoding certain footage types can just as well be slow, even more so with no hardware acceleration available. Could be perfectly normal behavior....

Reporting an audio/video issue with a TV show from a Season Pass? How?

I would like to report some audio/video issues with the latest The Unit and The Seeker episodes but I can't find them in my Purchase History??? I own a Season Pass for both. Any idea how to do it? I'm lost. Thanks!

Is this the lack of audio on "Shadow Riders"? I've just got to that episode, and I tried to report the problem, but the whole series of hoops you have to jump through seems to have changed. Rather than get to the page where you add comments for the problems, it merely sends you to an internet link on apple that has no bearing on the problem.
If you open your account information (store > View my account) you can click your purchase history there. The theory is that you find your program, click the arrow next to it, then click "report a problem" and it should allow you to enter a comment, or the problem... Anyone else having this troubvle?

Streaming audio/video issues

When I attempt to play video (Hulu, YouTube, Netflix) or audio, my IPhone 5c goes into this continuous buffer mode. How can I get audio/ video to stream again?

You are joking right? establish an ethernet connection?
We try not to joke on the forums. If you are using 802.11n 5 GHz, that might do it if the Blu-Ray player and Time Capsule have close to a line-of-sight relationship. If 5 GHz won't do what you want, that tells you that the connection has insufficient bandwidth to provide the connection quality that you need.
If you are using regular "n" wireless at 2.4 GHz, ethernet will have about 8 times the bandwidth capability than wireless. Using 5 GHz, ethernet will have 3 times the bandwidth of wireless.
You may not want to consider ethernet, but it's hard to argue with physics. I've tried to stream high definition sources over a very good wireless network, but have not found a way to do this and obtain the performance that I want. But, perhaps another user has found the answer and will post to tell us about his workaround. I will be watching this thread.

Audio/Video Issues in Tour de LC

First off, I would like thank Adobe for producing this resource.
In looking through the various pages contained within Tour de LC, I have found a couple of minor issues with regard to some of the videos presented. A co-worker had found a video that had no audio, unfortunately I am not sure which module it occurred. There is some kind of captioning in the video so it may just be that there is no audio.
In LiveCycle Overview > LiveCycle Solutions > Life Sciences > Life Sciences Demo Module, the Life Science Demo video does not sync with the audio. The video seems to stop while the audio continues.
In the LiveCycle Overview > Resources > Adobe TV section, the Videos labeled 'Service-Orientated Architecture for the Enterprise' and 'Invoking a LiveCycle ES process from an Adobe AIR application' seem to be the same video.
Again, Thank you for this great resource. I am sure it will be helpful to a great many LC users and developers.

Hi Ryan,
Thanks for the input and compliments on Tour De LiveCycle.
Many of the videos in TDL do NOT have audio associated with them. They simply have callouts on the screen directing the user.
On the "LiveCycle Overview > LiveCycle Solutions > Life Sciences > Life Sciences Demo" I do not see the same behavior as you do...it seems like it is ok. Maybe it has to do with the network speed.
We will fix the link on the Adobe TV to point to the correct video.
Thanks for the input!

Audio/video out of sync (audio delay) with PowerBeats wireless earphones.

I am having a problem with audio/video sync between my PowerBeats Wireless earphones with my MacPro and MacBookPro. I have tried pairing, playing the video, pausing the video, turning off the PowerBeats, tuning the PowerBeats on, then starting the video playback again. I have the same audio delay so this not working for me. Anyone have an update as to how to fix this audio/video sync problem?

I am playing MPEG-4 movie files. I did open MPlayerX from my dock, then pulled down File to select Open which then did show the folder where these movie files are stored. Then I was able to select a movie file, open it, and use "Decrease Audio Delay" to closely sync the audio with the video. I say closely because it is not perfect. Rather than stepping each increase or decrease in one tenth of a second, perhaps a finer adjustment would have been in milliseconds. This is the adjustment that I have with my AVR to sync the audio with the video, so I know this is a possible increment adjustment. The perfect adjustment was in between -0.4 and -0.5 second,however, this was not possible in one tenth second adjustments. The closest adjustment was with -0.4 second rather than with -0.5 second. So, adjustments in milliseconds could have been very near a perfect sync. Perhaps later versions of MPlayer will offer the adjustment selection in milliseconds. Nevertheless, this is working much, much better than before. Thank you so much. I have spent most of this day researching this problem and you have come up with by far the best solution. This problem goes all the way back to 2010 and possibly beyond for Apple products. There are hundreds of reports documenting out of sync audio/video issues with no solution that works as well as MPlayerX. Even the Beats support staff have no idea of how to resolve the audio/video out of sync.

Audio / video sync issue in playback

for every recording i've made, when i play back the archive there is noticable lack of sync between the audio and the person's mouth. the video seems to lag behind by almost a second. the good news at least is that the delta is constant.
has anyone else experienced this? it's happening in any scendario i try, even if i'm just recording myself.
is the LCCS dev team aware of this? since audio and video streams are recorded separately, is there any way for me to programatically 'nudge' the streams into sync?
it's currently a show stopper, it looks really bad when the sync is so obviously absent.

finally getting back to this..
i did as you suggested and recorded a video of myself using the recording and playback examples provided with the SDK (the 2.2 newest version btw).
the de-syncing of audio and video is definitely there. it seems especially bad for longer recordings. however, an interesting thing i discovered in playback:
- sometimes, if i drag the playhead somewhere in the recording, pause, and then hit play, video and audio fall into sync.
- if i start playback from the beginning of the recording, audio/video is always out of sync.
i understand that the video and audio streams are recorded separately and thus played back separately. my guess is that when those streams are retrieved and playback begins, one starts before/after the other because they're not retrieved at exactly the same time. it seems some extra work is required to ensure that their playback commences at exactly the same timestamp within each stream.
i can provide my recordings as an example if required.
this is a total showstopper for me. it renders the entire recording service useless if the playback can't have sync between audio and video. i would be happy to help with testing this more. can someone from the LCCS team comment on this issue?
thanks

Audio and Video issue with Windows 8.1 upgrade on Ideapad n585

I upgraded my Ideapad N585 to Windows 8.1 the other day, took forever, but it made it through. Unfortunately, I now get boot erors for the Dolby software, and the AMD Vision/Catalysyt Control Center. Neither of these programs are able to start, from startup or even manually. They just won't run. Sound seems to come out fine still, but I do have video issues.
First off, my computer doesn't seem to recognize a HDtv as a monitor through the HDMI port. I still get an image, but it's set to current screen resolution instead of 1080i. I tried using the detect button to force it to look for a second monitor (my TV), but it showed nothing connected, though at the time I was using two screens. Now my monitor's screen resolution seems to be a little higher than my TV's, but it doesn't fit the screen properly, and will sometimes put a black border around the desktop, not using the full screen. I have also noticed, that when plugged into the tv, if a background program like a screen saver starts (and I am one of the few people who still use them, I like BOINC, sue me), it will reset the screen resolution to what it requires. When the program exits, the screen resolution stays, and that becomes the new max screen resolution until I restart the computer. So far, it only does this through the tv, if I run the laptop monitor alone, it doesn't happen.
I did try updating the software with what's available through the support site, but nothing happened. I even went as far as to use the Windows 9x~XP standbys of completely uninstalling, manually removing everything from the system registry I could find relating to these two programs, and then finally reinstalling the software. Giving the audio and video a complete clean slate to work from, and got no positive results. I restart the computer, Dolby and Catalyst won't boot, and blind to HDtv. Problems as described above still apply.
Anybody else have this issue? Anybody got a fix?

have you found a solution to this?
My computer updated to 8.1 without my wanting it to, I have the same problems as you. I installed the video driver because the brightness was locked on what I had it. (the bar would move but did not change)
I searched for brightness and n585 and I was able to find a driver, now brightness works but HDMI still does not. When I plug in the TV both screens go black with all 4 options in the "project" screen.
*edit*
this worked for me i stumbled across this
I unplugged the power cable with the hdmi cable plugged in. Hit (windows key+p) scrolled to duplicate and it worked.I plugged in the power cord back in and it still worked.

Playback pauses and audio sync issues with live video stream

I'm seeing playback pauses about every three seconds and audio sync issues with our live demo stream when using the OSMF/Strobe player. It happens on both our 2Mbps 720p stream and our 480p 750Kbps stream so it does not seem to be related to higher resolution/bandwidth streams. It also happens if I point directly to a stream asset or if I point to a .f4v with both streams listed for dynamic so it does not seem to be related to dynamic streaming specifically.
The same live streams play back very well without pauses or audio sync issues in the Akamai's dynamic player and even slightly better with JW 5.2.
I have viewed the OSMF/Strobe playback on three different laptops of various age (3 months to 2 years) and two are Windows and one is Linux. I have also tried the various buffering options on the Flash Media Player Setup and Strobe setup and it has not made a noticeable difference.
To see the stream with the Akamai player, go to: http://live.kulabyte.com
To see the stream with the OSMF/Strobe player, go to: http://live.kulabyte.com/osmf
I do not have JW set up for public viewing yet, but the two above show the distinct difference.
We are really hoping to start pointing our customers towards the OSMF player because of the support provided by the community and Adobe, but we have to get the quality of the playback to be acceptable first.
If someone has ideas on debugging I can PM the actual video assets to you.
Thanks,
Tim

Hi Tim,
You need to add this setting:
dynamicStreamBufferTime=8
The actual value can be higher or lower. The best practice is to use a value that is twice the keyframe distance. Anyway, try different values and see which performs the best for your content.
I know that the setup page does not contain this option and it is not documented in the UserGuide. We simply missed it. Sorry.
Also note that the dynamic buffering algorithms are not being used for dynamic streaming content. I tried to explain this here:
https://sourceforge.net/adobe/smp/wiki/Dynamic%20Buffering/
Looking forward to your confirmation that this solved your issue.

Why does embedded video cause audio sync issues?

Greetings all,
   I have a question that is perhaps best answered by an Adobe developer or someone who knows the SWF file format and various audio/video standards fairly well. When one drags an FLV file into the library in flash authoring tool, a window appears. If you click "Embed FLV in SWF and play on timeline", an awful message appears, "WARNING: Embedded video is likely to cause audio synchronization issues...". My question is: why would there be any audio synchronization issue? Is this really just a bug/unimplemented feature? Or is there some fundamental shortcoming of current versions of the SWF file format that does not allow for the FLV audio/video signals to be properly encoded in the SWF file? Or is it that the flash player plays SWF and FLV data in fundamentally different ways and that even if the audio/video is perfected sync'd in the SWF file, the fact that it's a SWF file causes flash player to lose sync?
   I'm guessing only a Flash developer could answer this (and probably not just any Flash developer!), so if there are any out there, please spare some wisdom for a poor lost SWF surfer.
   Thanks!

Hi:
Welcome to discussions!
From what I am reading, you are trying to use the audio that was in the original video-right? By that, I mean, you haven't added a voice over or music-just using the speaker's voice on the tape.
If so, you might want to try using something like a Fade Out or Fade In instead of one of the transitions that add or subtract to the length of the video
[Quoted from iMovie Help]
Some transitions (for example, Cross Dissolve and Push) shorten your movie by a few seconds, depending on the speed of the transition. For example, if you add a transition with a speed of 2 seconds, iMovie overlaps 2 seconds from the first clip and 2 seconds from the second clip as it renders the transition. This shortens your movie by a total of 2 seconds.
The Overlap transition freezes the last frame of the clip on its left and superimposes it over the next clip. Fade In/Fade Out blackens the last frames of the clip on the left and the first frames of the following clip.
[End quote]
Or you could try extracting the audio from the movie so that you could edit it and sync it that way.

Audio / Video Syncing Issues

Hello Everyone,
I own a 2011 MacBook Pro with a 250GB SSD and 8GB upgraded Ram. I'm currently using iMovie to create an hour long movie with images / audio / and voiceover in certain sections.
I have been working on this for quite some time and would like to be able to export it the same way I'm able to view it inside the Application. However, when I export the movie the audio / video / voiceover is off and it does not match with what I have worked on inside the project.
I have also tried breaking down the movie and exporting it in sections but the audio is still not syncing correctly on the export.
Please can someone help me out and help me explore my options.
Thanks in Advance,
Mauricio

Sorry for the confusion. To clarify:
The Video and Audio are OOS. Let's say that at the beginning of the Clip, the difference is ~ 12 frames off. Is it still that ~ 12 frames off at the end, or is it now ~40 frames OOS?
Though the best is to Capture with no OOS issues, the former is fairly easy to fix. The latter takes more work.
Also, whether the OOS is constant, or dynamic, might lead to figuring out where this issue is being introduced.
Good luck,
Hunt

Sync Issues (Audio / Video)

Like many others, apparently, I've spent untold hours putting together a ~50 minute project in iMovie '09, only to find that after exporting to iDVD, I lose sync. It's frustrating, but I've seen from this and other forums that it happens, and is related to using source material that is not 16 bit audio. In this case, my sources include horrible camera phone video, some video out of point and shoot still cameras, decent DV footage, and some high def out of a Canon 5D Mark II. So fair enough, but some questions about how to get out of this jam :
1. If I go through the clips in the project and look at them in Finder, or QT, or VLC, I can sometimes tell whether they are 16 bit, 8 bit, or whatever. But sometimes it just doesn't say. So I'd be grateful to learn how to tell for sure.
2. Once I've figured out which clips are not 16 bit, how can I make them so? Can I open those clips in QuickTime or VLC, for example, and export them out in another format that will not cause the audio sync issue? Is Garage Band of any help here?
3. Once I've turned everything into 16 bit audio, will it be sufficient to replace the offending events in the Event Library and then in the Project, or is that Project now irretrievably tainted with the other audio forms?
4. Is there a better way than what I'm suggesting in 2 and 3, above? For example, can/should I copy parts of the project into new projects, export them out in certain formats (which ones?) and then try to reassemble those exports into yet another new project in iMovie?
5. I do not have iMovie '06, and do not have access to it. But if I did, what would I do with it to make this better?
I do have Final Cut Express, but I don't really have the stomach (or more importantly, the time) for rebuilding this project from scratch. But if you tell me that's the only way out, I guess I'd do it.
Many thanks in advance for your help.

In case anyone comes across this in the future, I've resolved my issue, and it had nothing to do with audio bit rates. In short, there seems to be a well-documented yet unfixed but in which an export from iMovie can lose sync if there are either slow-motion effects applied to a clip, or if the slow-motion speed is custom rather than pre-set by the software.
I changed my clips to 100% and everything exported fine, with no sync issues. For more on this, see the helpful thread here: http://discussions.apple.com/thread.jspa?messageID=10618532#10618532

Audio/video synch issues

Hi-
I *Just* got a new Mac Pro last night and installed FCS with FCP 7. Updated everything.
I captured NTSC Dv video in ns 48K from my Sony HVR-m25U via firewire. The audio/video are a little out of synch.
It's been a few years since I've upgraded FCP. My last version was 5.1. Is there soemthing in preferences I should or should NOT check? I vaguely remember this issue from years ago but can't remember what it was.
Also, I currently only have 3gb of the installed memory int eh amchine. 16 gb are arriving on Wednesday. Could this be a problem?
thanks!!

Thanks for clarifying!
I am monitoring the audio through Bose speakers that are connected to the audio output of the compute

Audio/Video Publishing Issues

I've narrated three videos and have included two small flash videos into my project. When I publish the project, the video and the audio don't play. Any advice for resolving these two issues would be much appreciated. Thank you.

with RTMFP, video and audio can go out of sync if the data
rate of your stream exceeds your network capacity. video is
currently sent with 100% reliability, so once it's queued for
transmission, it's going to be sent (eventually). video is lower
priority than audio, though, so your audio data gets first dibs on
your network capacity. if the video stream's data rate is higher
than what fits in your network (after audio), the video data will
back up until its send buffer is filled, and new camera frames will
stop getting captured. in the steady state, this can look like a
multi-second offset between the video and audio.
try turning your video rate/quality down so that it fits in
your network capacity. video and audio should stay in sync.
with RTMP, there's one network transmission buffer (TCP's)
for all of the parts of your stream (audio & video). when you
have insufficient network bandwidth, the TCP buffer will eventually
fill up and video frames will stop being captured to compensate. so
while audio and video might remain in sync, the total end-to-end
latency will go up. when using RTMFP, the audio and video have
independent transmission buffers, so in cases of insufficient
network resources, the higher-priority audio should remain more
timely but video may fall behind.

Audio Video synchronization issues

Hi,
I have a video application that I am building - and
previously I used FMS and TCP connections for video. Now expecting
the latency to be much lesser with UDP, I implemented UDP in my
application and stratus as the RTMFP capable server. I used the
sample video phone application's tutorial do a simple sendStream
and receiveStream for video.
However, unlike the hosted sample application itself, my
audio and video are completely out of synchronization - about 4
secs!! I tried to look at the sample code to see if there were any
special settings that were made. I could not find any.
My questions:
1. Did Adobe make any special tweaks in their hosted sample
application? If so, what are they?
2. Are there any known synchronization issues with using
RTMFP connections for video?
3. Does anyone else also face audio video synchronization
issues?
4. If none of the above is true, what do you think my
mistakes are? Please let me know if I need to add more information
to answer this question.
Thanks in advance.
Rohan

Audio and video issue after Win 10 Upgrade - Split X2 laptop 64-bit

Any solution to the Audio and Video issues on Split X2 13" laptop after Windows 10 FREE Upgrade?? - Intel Core i5 processor- 4GB memory I'm sure others are have the same Audio/video problems: - there is Sound and video playback but the sound and video is repeated slowly forward....impossible to understand the audio. The video is clear but also being played in repeated frames as it moves slowly forward!- sounds coming out of the speakers ok - everything was working great on Windows 8.1 (before upgrading to Windows 10). there must be some kind of driver upgrade for IDT High Definition CODEC BEATS audio... is there a work-around until a real fix is provided?? Regards - VK

I have downloaded and installed the HP recommended IDT Audio Driver using the HP Assistant. The current installed IDT High Definition Audio CODEC driver is: STWRT64.sys 6.10.6498.0 The laptop was rebooted but the problem still the same.....Audio is garbeled and impossible to understand the words...video seems ok when playing Youtube videos.
