Video On Demand pixelation and audio drop out

Been having an intermittent problem with pixelation and audio drop with VOD for over 6 months now. Happens on all TVs/Boxes. Also seeing some Internet issues when this happens. I understand from Verizon tech that same circuit is used for both. After a reboot of router it usually clears for a while (1 – 5 days) but then comes back. It sometimes gets so bad that VOD movie will stop completely and I get an error message “VOD: The set-top box lost video due to a network connection failure [VOD_191]”. I have Cisco boxes. Router, ONT (fiber converter), and all boxes have been replaced but still no resolution. Verizon is struggling to find an answer so I thought I would put this out to the masses for any insights anyone might have.

It sounds like you might be hitting the space bar in hopes of getting real time playback. Sorry, but AE doesn't work like that, because it does totally different things from an editing application like Premiere.
And if you've downloaded the tryout version, you really ought to learn how AE works... and a short description is "it doesn't work intuitively". You can frustrate yourself in a hurry.
But this can really help;

Static and audio drops out

I am not sure if I am in the right Discussion area. If not, please advise where to post. After having work done (new mother board and power supply) on my iMac I heard a static or scratchy noise in the lower right side behind my screen while listening to iTunes the week after I got the machine back. Some songs(with more treble) were worse than others. My parents and I iChat every Sunday. The static now interferes with our iChats and the audio drops out and then will come back. They hear it more on their end than I do on mine. I tried turning the speakers way over to the left and that did help some when listening to iTunes, hulu but, not the iChat problem. My question is - do you suppose it is my speakers rather than another issue such as bandwidth or setting elsewhere? And if I were to buy external speakers would those then just amplify the existing issue? The computer on the other end is an iMac running snow leopard. Could it be that the microphone wasn't put back in correctly during my last repair?

Hi paperchase
That kind of sounds like the right internal speaker is bad or loose and the Internal Mic is picking up on the noise from it.
One thing to try before committing to a 2.0 or 2.1 External Speaker System, is to test the iMac's external output sound with iPod buds or a set of headphones. That at least will give you a better idea if the problem is with the right internal speaker or something worse like the sound card.
Likewise if the repair work was recent, then perhaps you should contact the service provider and report that it came back with an intermittent or rattling right speaker.

Dropped Frames and Audio Drop Outs???

PowerMac G5 1.8GHz Mac OS 10.5.7 4GB RAM 250GB Hard Drive
Final Cut Express 4.0.1
Sony DCR-TRV310
When I attempt to do a direct capture via firewire I am only able to get one or two seconds of video before FCE complains that it has reached the end of the tape.
If I try to capture from the tape instead of direct it captures OK but the video blinks like it has dropped a frame and the audio is full of drop outs, pops and other noises. Those noises are not there when I listen to the tape directly on the camera.
Is my machine to slow?
I have tried several different firewire cables and all of the firewire ports. I have rebooted and made sure I have all the latest updates.
I also have a DCR0SR80 and a DCR-SR220 but neither of those have firewire however when I import the video into FCE (after converting formats) that video plays fine. I would really like to use the TRV310 though since I can capture directly.
Suggestions? Thanks.
- C. Thomas

I have a MacTopus (8-core) and also had one particularly bad video import. FCE 3.5 would complain and stop importing so often that I gave up and used iMovie to import the DV footage from the camera. Then I imported that footage into FCE. Apparently iMovie is not so picky and tends to ignore timecode info when importing. If the timecode info is not critical for you - try iMovie.

Sync Issues and Audio Drop-out from FCP to DVD Studio Pro

I have edited a piece in FCP 5.1.4 and all audio/video is in perfect sync. I have been using this program for several years with no issues, until now. Upon exporting with compressor and importing into DVD Studio Pro, the audio is out of sync by 15 seconds and after that first 15 seconds there is simply NO audio, period.
Any ideas? Please send the calvary...tight deadline and the hanging rope is getting shorter and shorter by the minute!
Thanks

Could be something got corrupted in DVD SP (preferences). I have had my audio act strangely and playback getting bogged down. Repairing permissions and deleting prefs works for this one for me. Did you do any recent upgrades to the OS or QuickTime?

Problem : Audio drops out on multicast

We are using Quicktime to view multicasted feeds. We read in the SDP file, Quicktime goes off, does the connect...all is well..until you try and fast forward to get rid of the latency (customer wants < 100 ms, which Quicktime can do fine). If you get to the end of the buffering, video still works fine, but audio drops out and does not come back. There is also some audio pops while the fastforward occurs. This behaviour is the same on both the standard player and the wrapped version.
Have not seen anything in COM interface that can let me see how much buffering is left, otherwise I could simple keep poking fastforward until I have minimal buffer left.
Here is the SDP file we are using
v=0
o=- 1 1 IN IP4 127.0.0.1
s=RTP session
e=NONE
c=IN IP4 239.1.1.8/3

There are only two possible causes I can think of:
1. The fiel your'e using out of FCP is bad.
2. The encode that DVDSP created is bad.
> After exporting to DVD using compressor, the audio on the DVD completely goes away 49 seconds in. It's there on the master in FCP, but not on the DVD. It goes away in simulator too. <
How did you export out of FCP? I always use a self-contained movie. If the movie includes the audio, there's a problem in DVDSP.
If you are exporting to MPEG2 out of FCP, you must figure out a way to check the audio portion of the file.
If it goes away in Simulator there's an issue happening right at that point. Does it play in the DVDSP timeline? Does it play in the media viewer of DVDSP? Can you open the exported movie in QT Player?
Is there anything significant about the 49 second location?

Audio drops out when following video to external monitor

When I play a sequence to an external monitor, the audio drops out for 2 to 3 seconds after changes on the video track, and then pops back in with no interuption in video output. It doesn't happen at every cut, but it's consistent in the places it does. I thought it might be caused by the size the project has become. So I exported the sequence as a quicktime file, closed the lage project, opened a new one and exported the new file and played it and it happened again, even though there were no edits. It doesn't occur at all when I turn off external video, and play it on the computer. I connected a new firewire from the computer to my DV deck, restarted the computer, but it keeps happening.
Is it that the dramatic change in color, light and compostion crowding out the audios ability to follow the video through the wire?
I'm completely stumped. The next step will be to open the computer and try to blow any excess dust out. I do this periodically anyway, and my last time was two months ago, so I'd be surprised if it works.
Maybe the G4 with 2G processing power can no longer handle the program, but it shows no sign of stuggle in any other way.
My clients are starting to grow restless.

Thank you so much X & Paul, for your suggestions. Although they didn't solve the problem, they kept me hopeful enough to continue my quest for an answer. After exhausting all effort to find the problem in the audio, I decided to focus on the video. So, I tried correcting the excess luma on the consolidated QT movie, and suddenly the problem was fixed. Because of the different levels of correction I'd need for each and every cut in the original sequence, and the precious time it would take, I'd planned to save it for the color correction stage, a mere 2 weeks away. I remembered how illegal white would often cause the image on some monitors, specifically consumer TVs, to waver for a second. But this was happening all the way back to the DV deck's audio meter, so I never expected it to be a luma issue.
I assume that the outdating capacity of my G4 played a part, but I wanted to write back with my thanks, and to impart my illuminated wisdom to the next perplexed soul.
Thanks again,

Video & Audio Drop Outs on Macbook Pro

I have a MacBook Pro with Version 10.7.3, 6 months old. Just recently when I play video, regardless of whether it's in iTunes, iMovie, or embedded in Keynote the video sticks, audio drops out for 1 -2 seconds or the shot freezes. What causes this and how is it fixed.

I apologize for the audio drop outs. I have sent you a private message to get account information from you so we can reprogram your boxes.

Audio drop outs and continuing problems- Apple Support informed again.

Hi All,
Have had various audio problems with iMovie transfer to iDVD 6. iMovie had the problems initially but a weird trick seems to be helping me.
Copy a random new audio track into my film, paste it, then cut it out then empty trash..... all of a sudden my audio is clean again and perfectly in time with the video. I have informed the iMovies people in Ireland and they are at a loss to explain why this is now ok.
BACK to the plot and iDVD 6.
When I try to export this project from iMovie in iDVD 6 it either becomes an audio garbled nightmare or if I try and import into iDVD 6 I get audio that gradually becomes out of sync with the video visual. I know that this project was recorded in 16 bit audio so no joy there.
I've told Apple in Ireland that there are major audio issues with iDVD 6's audio set up + something they were apparently unaware of. I was assured that the tech dept's would investigate and solve. I am really surprised that they hadn't seen this problem in this forum!!
In the meantime any advice is very gratefully received. I'm on an Intel G5 Imac with 1.83ghz 1Gb sdram and 250 GB HD. So Software is currently limited!! I desperately need to get this project to DVD!!!!
Many thanks,
GUY

SAME EXACT THING HERE. This is what I posted in a diff thread:
2013 iMac 1TB Flash Drive
OS 10.8.5
Constant audio drop outs using Apogee Duet. I have to unplug and replug several times to get the system to recognize it. Sometimes when it is connected, Audio Prefs doesn't even recognize it and it shows up as "Unknown". When I click Audio Prefs before I get in, I get the spinning beachball and it takes a while for it to open. I have been in touch with Apogee but to no avail. It seems to work on my 2013 Macbook Pro, but I haven't tested extensively. It seems to get tripped up if I'm working in Ableton and get a Facetime call or if I try to use Youtube / Soundcloud. The system gets noticebly slower. When I switch back to Ableton, Duet is recognized (sometimes not recognized at all) but I cannot play anything inside the project window.
Not sure what to do at this point

Audio drops out while video continues to play just after making a cut!

I've been using Adobe Premiere Pro for a few months now and I use it to edit my YouTube gameplay videos. Here is everything I am doing in Adobe Pr:
1. Create new project
2. import my raw gameplay video (m2ts file)
3. import my wave sound file (my commentary)
4. Put them on the time line and play the video (it works then)
5. make a cut somewhere and the GAMEPLAY audio drops out not the video or my commentary.
The same thing happens in Adobe Premiere Elements as well. Should I convert my m2ts files to MP4 or AVI or something??? Please help

Last week, this song played fine on the burned copy.
Is this problem now showing up in the iDVD preview mode? Or is it with subsequent burned DVD's?
Go back to your project in iDVD. Go to File>Save as disk image. This will create a file that can be viewed on your computer's DVD player. The disk image will show you how your project will appear when played on a standard DVD player. See if this problem is repeated. If everything is fine, go ahead and burn the DVD using Disk Utility.
I hope this helps.

Audio drop out in Encore AND Premiere

Strange problem. I am trying to burn a dvd with Encore. All the files play fine in QT, all the audio is there. once in Encore, it randomly picks clips to not play audio AT ALL. Sometimes it will play part of a clip then drop out audio. I have re installed and tried several tricks, like bringing files into Premiere Pro to render out a different file type. Now my premiere wont play the audio randomly either and the file produced has no audio! all other audio/video apps running fine. Not sure if its a Adobe Production Studio problem or a glitch in my system, thou as I said, rest of system works fine.
Any suggestions would be greatly appreciated!!
Steve

Well, thanks for reply but I got it to work after several work arounds, thou my Adobe products still seem to be working strange(Not opening as I closed them, etc.)
So, foe giggles, here was what I was working with.
I digitized some footage from a digibeta into my Avid where I exported Quick Time reference files to be used in After Effects.
In After Effects I exported Quick Time Movies with Blackmagic codec,8bit, with 4800k audio, uncompresed. All where NTSC 29.97. Files play in Quick Time/Windows media player no prob.
Installed Blackmagic codec on my home system for the final build with Encore2.0 DVD and thats when all the fun started. Encore would play files fine but then start to randomly drop out audio at burn.
To solve this I pulled QT's into Premiere Pro2.0 and exported WAV files to swap out for in Encore. This almost worked until Premiere started to mimic the Encore problems with random audio drop out.
After several retarts of the programs ( they would both have ASIO driver problems and quit audio. I replaced my driver, still same problem. whew!)I got the files all rendered.
Wow, still with me? Thanks! so long story I finally got the QT re rendered in Premiere to DV files that worked fine in Encore.Still think I have a system bug or somethig due to the fact these programs and Photoshop too are acting "wonky", crashing out or locking up, etc.
Thanks for the intrest!! any suggestions on system checks would be great!

N95 Recorded Video: Video and audio is out of sync

Audio and video is out of sync when I play videos recorded with N95 on my PC. If have used different PC applications to play the video, but all exhibit the same problem.
In the beginning of at video it seems that the audio is about 400milliseconds ahead of the video - you hear the sound first. The different in audio and video is not constant. In a long video (30-50minutes) it is quite unpretictable how video and audio is out of sync in the end.
To experience the problem yourself record a long video sequence with a N95.
1 .Record something where it is easy to see if video and audio is in sync.
2. Transfer the recording to a PC.
3. Play the recording using VLC (www.videolan.org)
Another way to experience the problem is to convert the recording to AVI format at play it in MediaPlayer or WindowsMovieMaker. To convert a N95 video recording to AVI format use Mp4Cam2Avi.
http://sourceforge.net/projects/mp4cam2avi/
The video recording settings I use on my N95 are:
Best Quality
No Video Stablisation
Firmware version 21.0.0.16.
I think the video quality of N95 recordings is quite good, so I would really like to be able to view and edit the recorded vidoes on my PC.

You can edit videos on your PC, just converting them to AVI then using any Video Editor on the PC.
Yes while editing separate the audio channel from the clip and reinsert at the begining of the clip. This will minimise sync issues.To get accurate sync increase the timeline so that you are able to the see audio squiggles as a waveform.

Video and audio goes out of sync when imported into Premiere

I have some videos ripped from some DVD that an acquaintance made, with an open source program called HandBrake, with the default "high profile" settings. When I play it both in VLC and in Quicktime, it plays just fine, but when I import it either in Premiere or in After effects, the video and audio goes out of sync (the video ran faster than the audio and when the video stops, the missing audio is trimmed).
Video info according to Premiere (in Spanish but you may get the meaning).

"HandBrake, these days, is almost entirely about H.264 video, aka MPEG-4 Part 10. HandBrake is migrating to quality-based encoding."
Hmmm. I use HC Encoder to make my DVDs because it's the only free encoder I've found with the much more professional Constant Q encoding option. But HC Encoder doesn't do HD sources for Blu-ray, so I've been wondering if I'd be stuck with the lame-*** consumer CBR and VBR options most encoders provide (including Adobe - hint, hint) when I eventually start working in HD. This is a very interesting program, Handbrake. I will have to check it out.

Exporting (in H.264 format in HD 720p 23.976 preset) and audio comes out separate while video file is a .m4v instead of .mp4

Using Premier Pro CC 2014.
Exporting (in H.264 format in HD 720p 23.976 preset) and audio comes out separate while video file is a .m4v instead of .mp4.
Anybody know why audio and video are exporting separately? I can't figure out why. Help is much appreciated.

Thank you for the quick response. Unfortunately, that doesn't fix it.
I have the same issue when I try to export it through Adobe Media Encoder. I even tried to go through using After Effects and export through Adobe Media Encoder with the same results. I'm wondering if I might be better off uninstalling then reinstalling all my adobe programs.

ITouch and Pandora app....audio drop outs

Anybody having audio drop outs when using Pandora? It used to work flawlessly on my home network...nothing changed except maybe the update from Pandora in Aug? Anyway- tried the Pandora app on my Apple network at work...no problem. Is it my home network?...My network is secure...I have a cable modem and Time capsule wireless router. What is REALLY perplexing is that AOL radio app. streams fine to my iTouch.
Please anybody have a solution or similar problem with a fix for this? This was/is the best app for the iTouch and a speaker dock! So frustrating.
Tried reinstalling the app.....no luck
...all updates are current.
any thoughts?
Thanks-
Steve

I saw that post...but I'm not sure it applies to my situation. It doesn't seem to be connected to when my screen is locked or not. As I stated, It works without a hitch at my work but at home it has the dropouts. I would normally think...well it HAS to be my connection or speed or traffic at home BUT Pandora used to work flawlessly...it probably started having the drops after the update. Maybe the locked screen bug has something to do with my problem but I'm not sure. Why would it work at my work w/ an apple router and NOT at home with an apple router?...just plain weird...
I get buffering with LastFM if that is any clue for you? I don't get any buffering with the AOl radio app.
As a note I get no issues when I listen to my Pandora on my desktop both wirelessly and wired....so it HAS to be an iTouch/Pandora issue. I hope you are right that the update will fix my problem.
Thanks
