DMP-4310G Multicast video out of sync issues

Hi!
Currently I have following problem with DMS:
I have couple of DMPs connected to the same L2 switch with the identical configuration (same startup url, same buffers config etc.) and a multicast streaming server which streams (by UDP multicast) some live video to the DMPs.
Video codec is h264 (1920p,high [email protected], bw 6000kbps,29,97fps).
The problem is that after some time (6-15 hours) the video on the screens become out of sync (i.e. screens show the same video but with some delay (1 to 5 sec) between the same frames on 2 different screens for example).
DMM and DMPs - 5.2.2.
Can you advise me on that problem?

Hi again
I actually think my problems is very much similar to this one:
http://forums.adobe.com/message/2598909#2598909
Could it be related to H.264 and mainconecpt not doing things right?
When I try export the excact same project using Windows Media HDTV 720 - jsut setting the FPS to 50 instead of 25 it comes out nice. Looks a bit more blured to me, but might just adjust some parameters to get it right?
So i guess this issues with some periodic and ad hoc sync-issues is related to the H.264 mainconcept codec? Is there any other and better codecs for H.264 and how do one get them installed to use them inside PPro CS4?

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 And Video out of sync in Final Cut, but not in quicktime

I heave searched the forums to no end to find the solution to this issue, unfortunatley, I have not solved the problem.
I am using Final Cut 4.5 on a G4 running OSX 10.3.4. This system has worked perfectly for years with no problems. Neither the system, hardware, or software has ever been changed on this machine. Suddenly last week, despite perfect sync while previewing the capture, the Audio and Video were of sync in Final Cut, but when checked in quicktime, there were no problems. That is how I eventually figured out this was a final cut problem.
By out of sync, I don't mean it is by a specific number of frames that can be adjusted and then everything is fine, the sync seems to drift so that if you edit the audio to be in sync in one part of the video, it won't be at the end. Also, it is out of sync from the first frame played, not a gradual drift.
This is definitely not an issue of frame rates or final cut settings as will be evident by the steps I took below to find the source of this problem.
This is what I did to attempt to fix the problem:
- Check drives using disc utility and repair permissions
- Remove Final Cut Preferences using Apple guidelines
- Switch hard drives
- Delete Final Cut and reinstall newer version of final cut (since the capture files played fine on Final Cut 5.1 on another machine)
- reinstall entire OSX 10.3.9, wiping the hard drive and reinstalling Final Cut 5.1
- switch ram slots, and even replace ram with different sticks from another G4 machine
None of these solutions worked. Is there some hardware problem with my G4 that is suddenly causing Final Cut to play audio and video out of sync?
Hope you can help, otherwise this otherwise great G4 is going in the dumpster!
Thanks

For what it's worth, I'm having what looks to be the same problem. Driving me insane. Here's what's going on-
Editing in FCP 6.0.2
QT was just updated to 7.3.1 the other day (hmm)
On an MacBookPro machine, OS 10.5.1
Software updater says everything's up to date of course.
DV-NTSC 24p (23.98) Advanced Pulldown Removal (footage was shot at 24PA on a DVX100b)
In Quicktime, the file previews fine, everything's in sync, everyone's happy. In FCP, the video and audio are wildly out of sync. I did a test inside of quicktime and sliced out a small portion of the media clip and did a "save as" and this small slice played in sync in FCP. However, this did not work for the entire clip. Clip is weighing in at 5.58GB for a 32 minute run.
I'm trying to multicam 2 tapes together and manually syncing these up is proving to be difficult at best. When anyone gets any ideas/leads/patches, let us know.

Audio and video out of sync when using quicktime conversion

hello,
i am editing a hdv project and want to export to quicktime. the client needs it in a specific size (700x394). they do not want the video in the file compressed, just the size of image. they are compressing the video through flash for the web. anyways, i used to just use quicktime conversion, custom size and use 700x394, but now when i do that the audio and video are sparadically out of sync in the product. the wierd thing is that the project plays fine in the timeline, but when i export the problem occours. i then, exported to a full res fcp movie and it is fine. then tired reexporting through qt pro to 700x394. when i did this their were no sync issues but the quality of the file was not so good, it look more pixely, certainly not as good as when i did it using quicktime conversion.
how can i export through fcp to get the 700x394 file? someone said 'use current settings' instead of using quicktime conversion? how do i do this? what do i need to do and what are my settings?
any help is appreciated. thanks a ton in advance.
cheers,
clay

What format are you converting the HDV to?
If it's animation, it is quite possible your computer can't pull the data rate. In this case it would be a processor / hard drive issue not an out of sync issue.

Buffering pauses and audio/video out of sync, single RTMP stream w/ simple embed

Hello,
I am running Flash Media Server on my dedicated CentOS host, and finally connected a single RTMP stream fine and am able to embed and play back the stream, but I am getting constant buffering pauses (approx every 5 secs) and audio/video out of sync by at least 5 seconds. My CPU with Flash Live Encoder is a powerhorse, never over 25% processor or ram usage while streaming, and my upload internet speed is averaging 6-8 mbps which should be more than adequate. I fear the issue is server side, however port 1935 is open and in use, not firewalled on CPU nor the host.
Any suggestions would be great.

IMovie Problems: Photo import and audio-video out of sync.

Photo import problem:
Some times, I have problems importing photos onto my new project, the photos will appear to be that just one same photo when played. It does not transit to the other photos following the first, it's just stuck on the first. Is this just an issue with iMovie '11? Are there any other ways to resolve this problem?
Audio-video out of sync:
I've checked some other discussions but I'd like to raise this issue again for APPLE. There are problems exporting my 7-minute film - the video and audio go completely out of sync no matter what format I export it to. There are not a lot of clips used. I'm now trying the method to detach the audio files from the video, hopefully it works.
These issues are bothering me, in addition to a failed firmware update on Mac OSX 10.7.2 a few weeks ago. I couldn't open my computer and I had to go to the Genius Bar to have them help me backup my files on my computer and reinstall the whole system again. Anyways, any help to the above iMovie issues are greatly appreciated. Just wish that Apple will address these current issues and not just focus on improving their products with awesome features ._.

Anyone noticed Quicktime 7.4.5 causing out of sync issues for online vids?

Since 7.4.5 all Quicktime video clips I view online in Safari have audio out of sync with the video (by perhaps four frames). Anyone else seeing this?

I do not use Safari. However, I have no problems w/out of sync issues using the +latest versions+ of FF, Camino & Netscape.
Have you tried other browsers to rule out Safari as being the culprit rather than QT? Are you using the latest version of Safari?
What troubleshooting methods have you tried to resolve your issue? Need this info to avoid the +"been there done that"+ senareos.

Audio and video out of sync on short recordings

I've scanned the discussions and see that alot of posters are experiencing
the same problem I'm having which is recording quicktime movies
and getting audio and video out of sync.
In most of those posts the responses seem to be that the problem gets
bad if you're making a long recording. I'm experiencing that, but...
...I'm also having the same problem on really short recordings...less than a
minute. I've coming video and audio out of my cable box, into a SONY DSR-11 VCR, then firewire out of the deck into the computer, recording the movies with Quicktime 7.1.6.
I know it's coming out of the cable box and then out of the SONY deck via firewire in sync because when I log and capture through Final Cut Pro, audio and video are in sync in preview and playback. I don't want to use Final Cut Pro to capture the movies because I want to end up with MPEG4, and I'd have to go through an extra conversion process out of FCP.
Any thoughts on why even short recordings through Quicktime are out of sync?
Thanks.

I'm having similar problems transferring VHS video to Quicktime. Another problem I'm having is when I transfer a VHS video to iMovie and then export the video to H.264 format, I have similar sync problems, even though the iMovie seems perfectly in sync.
I'm going to try to transfer several alternative video formats (video from my cable DVR, Video from live TV, and video from a digital mini cassette to try and figure out whether the VHS format is the culprit. Will keep you posted.

Video out of sync

We have now 5 Final Cut pro machines that have replaced old media 100s. We are using the AJA Kona Cards and Sony Beta Cam Decks. UVW1800's I think. We are running component out to the deck and then composite out of the Deck to the Monitors. The video is in sync to the deck but not to the monitors. It will playback in sync once recorded. But the signal from the kona card going through the deck to the monitor is out of sync. I have tried lots of things including using sync generators (black bursts) but nothing seems to keep it in sync. Even once in sync the video will roll. It is I realize more an issue for the editor as the final product is in sync but does anyone have any clue as to why I am having this problem?
G5 Mac OS X (10.4.4) Final Cut Pro HD

Are you playing the audio thru the card too, or monitoring it out from the computer directly? Because if you monitor it from the computer then there will be a delay. But from the card or deck, there shouldn't be.
Also try posting this at www.creativecow.org in the AJA forum. That place if full of AJA users.

Audio video out of sync?

Every movie I have rented and purchased the audio is out of sync with the video. If I pause the movie sometimes it goes back into sync but doesn't last long before it goes out of sync again. I have been trying to resolve this issue for the past week. I have turned off everything on the computer that manages audio, made sure all drivers and software is up to date. I have uninstalled itunes and reinstalled. I've set itunes and windows bit rate the exact same and nothing seems to fix the problem. I am running Windows 8 on a new Samsung laptop, previously I was using a Gateway laptop with no problems. From my reasearch the past couple days i see this has been on on going problem with itunes users and I hope someone has a fix. I just rented a movie from Xbox Video and it worked perfectly. I think I am going to have to make the switch to Xbox but I have movies I have downloaded to itunes and would like to watch them.
Any help would be appreicated.

Hello bjwilson22,
I was researching the symptom you describe and reocmmend this article named Troubleshooting iTunes for Windows Vista or Windows 7 video playback performance issues found here http://support.apple.com/kb/ts1718
It is pretty length, but also thorough and I feel has the best advice to help troubleshoot the issue.
All the very best,

Audio/Video Out of Sync (PE 10)

I have read some posts regarding this, but they have not been helpful.
I recordered audio/video with an ASUS Transformer Pad Infinity TF700T in 720p .mp4 format.
When importing into Premiere Elements 10 on a Windows 7 (64bit) PC, the audio and video are sometimes out sync when editing, and when they are rendered to the final product, they are always out of sync.
I have tried changing to other formats (.avi), as some people stated that variable frame rate issues can come up when using a non-camcorder to record video, but the .avi actually made it worse, to the point that only the audio played.
I turned my PC off and on again, and killed all background actions on the PC. The video plays fine in Windows Media Player and VCPlayer.
If anyone has advice as to how to fix this, it would be greatly appreciated. I've spent 7 hours on this project, and am more frustrated than ever.
Thank you.

I have downloaded your AVCHD.mp4 video, checked its properties, and studied its performance in Premiee Elements 10 Windows 7 64 bit from the point of view of import, playback of rendered Timeline in Edit Mode monitor, and playback of an AVCHD.mp4 export of that Timeline content. I stared into the monitor to watch the lip movements as the sound played back. In any of the following I have not observed any out of sync audio.
MediaInfo basic properties included
a. AVCHD video compression, frame size 1280 x 720 @ 15.119 progressive frames per second (variable frame rate with minimum = 13.501 and maximum at 18.793)
b. AAC audio, mono.
Premiere Elements 10 project preset that I used was
NTSC
AVCHD
AVCHD LITE 720p24
In Project media, Interpret Footage told me that it recognized a frame rate of 15.0710.
Rendered the Timeline content and watched the lip movement as I listened to the audio. No out of sync audio.
For export,
Share
Computer
AVCHD
Presets = MP4 HD720p24
under the Advanced Button/Video Tab, I set for 1220 x 720 @ 15 progressive frames per second. The export settings dialog under Advanced Button/Video Tab looked like the following
I watched the playback of this AVCHD.mp4 export and again did not observe any out of sync audio.
All video playbacks were with Windows Media Player 12.
Have you worked specifically with the video clip that you provided for download? If you have and you
found out of sync audio, then I am suspecting that this might be a system rather than a video problem.
It is a way out stretch, but...there have been some strange display goings on with Premiere Elements 10 and NVIDIA video card drivers recently. For all these cases, the answer has been rolling back the video card driver instead of the typical "making sure you have the latest version of the driver installed". What video card are you using in your computer?
Please review and then we can decide what next.
Just a note...this is a public forum with many viewing. Please do not post anything that would invade your privacy or is of a personal nature.
Looking forward to your follow up.

Audio & Video out of sync in itunes but not quicktime

My audio and video has never been in sync in itunes. It has been years since I have been able to watch a movie using iTunes. When I use quicktime, everything is fine, but when I use itunes, the audio and video falls out of sync. I have tried all of the suggested steps from http://support.apple.com/kb/TS1718
I am running iTunes 10.4 - 64 bit version
I have Windows 7 64 bit
6 GB or Ram, Quad core i7 920 cpu
2x Nvidia Geforce 285 - I have tried running it in SLI and not in SLI
I'm constantly updating my drivers and as of today (7/24/11) I have everything up to date.
Does ANYONE know whats going on?! I love using iTunes, but this is just rediculous!

I have the exact same issue, it is preventing me from using iTunes to purchase Movies and TV Shows.
I too have an Intel i7 - 6GB RAM, and GTX 460.
Drivers are up to date.

Audio and Video out of Sync in Encore 2.0

Here's my issue:
I opened a project in Encore 2.0 that was an Encore 1.5 project. I have one timeline with a 2 hour movie and the AC3 audio file that goes with it. Encore 1.5 played the audio and video in sync from the timeline and burned discs with the audio in sync. The video is an MPEG2 file encoded at a 3.1 constant bit rate.
In Encore 2.0, when I play the timeline, the audio becomes progressively out of sync as it plays. Within the first few minutes it's maybe a frame or 2 off. By the end of the film it is about 18 seconds off (audio is playing ahead of the video).
Is this a result of Encore 2.0 conforming the audio file? If so, how am I (or anyone) supposed to attain sync between video and audio in Encore 2.0?
I have Encore 1.5 and 2.0 both installed on the same machine. As a test, I opened the project in 1.5 and played it, everything was fine. I closed Encore 1.5 and opened the project in Encore 2.0, and the audio is out of sync.
Any comments, ideas or suggestions?
Mike

Joe,
I tried creating a project with the original WAV file and it's corresponding video and found that the audio and video were still out of sync. I did a little more testing and discovered that the audio is actually being played correctly, it's the video that is not being played correctly. Here's what I did:
I opened the WAV file version of the audio file in Premiere Pro and noted where a hammer hit in the video occurs (01;40;30;28). I then opened Encore 2.0 and imported the video and AC3 version of the WAV file, placed them in a timeline and the audio's hammer hit is right where it's supposed to be (01;40;30;28), but the video's hammer hit occurs at 01;40;43;18.
Next I went into Encore 1.5 and brought in the AC3 audio and video files and placed them on a timeline. I went to 01;40;30;28 in the timeline and the audio and video were both at the frame they should be at that timecode.
Seeing how the video appears to be playing incorrectly, here's some info on my video files:
I have 4 versions of the same film in varying encode rates with the same start and end timecodes. All four files were encoded on a Sonic DVD Creator authoring station using hardware to encode. The files are encoded at the following rates: 2.9 constant bit rate, 3.1 constant bit rate, 3.4 variable bit rate and 4.0 variable bit rate. They are each NTSC with drop frame timecode. All four files play correctly in Encore 1.5 but incorrectly in Encore 2.0.
This almost seems like a drop frame/non-drop frame issue. Do you have any ideas?
Mike

In all your information, I did not see what computer operating system your Premiere Elements 12 is running on? Have you updated 12 to the 12.1 Update, using an opened project's Help Menu/Update? If not, please do so.
Your issue may relate to the details of your "VOB file" and how it was ripped/copied from the DVD-VIDEO and DVD disc to get it into a Premiere Elements project.
a. project preset set for NTSC DV Standard or NTSC DV Widescreen (whichever corresponded to your recording details)...or PAL equivalent.
b. DVD disc in burner tray
c. Add Media/DVD camera or computer drive/Video Importer/.....
It does not happened often, but if audio is out of sync and you are not using the above route, then consider the Command Prompt way described in the
following
ATR Premiere Elements Troubleshooting: PE: DVD-VIDEO/Seamless VOB Ripping
A just in case note, contrary to some, it is not necessary to convert VOB (VTS_01_1.VOB video file and any files in that series) to any other format in Premiere Elements.
Please review and consider and then we can decide what next.
Thank you.

Audio and Video out of Sync after Pro Res export

I´m getting an audio/video sync issue when I´m exporting to Pro Res.
I started off in a HDV1080i50 sequence. Audio sampling rate is 48khz. (16 bit depth)
The sequence is less than 20 minutes long. It plays correctly on the timeline.
When I export the sequence for DVD and view it on a set top it plays absolutely fine.
When I export the video to ProRes (422 HQ - I used Export using Quicktime Conversion) and the audio to AIFF, they quickly go out of sync. This was brought to my attention first by the guys who were making the DigiBeta master, and when I view the exported material in a Pro Res sequence I can see it for myself.
The audio and video clips are of the exact same duration.
Possible issues...
Some of the narration was recorded at 44.1 khz. I didn´t resample it (I´m still a learning novice..).. but if that is the issue should it not have affected the DVD as well? All the other audio in the project is 48khz.
Most of the material is HDV1080i50..but one clip used was originally an NTSC clip and therefore a different frame rate. However I converted it to a 25fps clip and this is reflected in the vid rate column in the browser where it says 25fps.
Final point, the exported AIFF files..when I import them back into the HDV1080i50 sequence and play back, it is perfectly in sync.
Any help would be greatly appreciated.

First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores.
