Audio problems after burn

I've burned my DVD and the audio works fine throughout with the exception of 2 keynote slideshows I put on the disc. I exported these slideshows as quicktimes through keynote, and the video works fine, however the sound doesn't show up. When you do this with keynote, it seperates the movie into a video and "soundtrack" file. The problem may come from this, however in the preview in iDVD the sound is there. Now I've only got iDVD 5 and I had to save the dvd as a disc image and then burn it to a disc with my third party burner. Should I try the disc image again or should I try and reformat these quicktime (movie) files
Thanks everyone

"If you make a presentation which has a background track which plays throughout the presentation (as opposed to per-slide), KeyNote exports it as two Quicktime movies. One contains the movie of the slides (chapter marked). The other contains the soundtrack (and it's named moviename_soundtrack.mov). The first movie references the other, so that they can play synchronously. However iDVD does not import the soundtrack. If you check the asset list, you'll see that it assumes the soundtrack is in the main movie. To make matters more confusing, playing the movie in iDVD works fine. That's because the DVD simulation uses Quicktime to do the playing, and it does the right thing. However, iDVD's failure to recognize the linked movie causes another bug which caused me no end of grief. When viewing a chapter listing page which contains thumbnails, the soundtrack plays! Furthermore, it plays once for each thumbnail. Of course they are slightly out of sync, and the result is incredibly weird. It even plays the soundtrack while it's encoding the chapter sections! Again, the problem is that QuickTime sees the reference, and although iDVD is presumably telling QuickTime not to play the audio track, it doesn't know that QuickTime is playing the linked audio track."
"I attempted to work around this problem by directly editing the iDVD project plist file and changing the audio soundtrack to point at the correct movie. That sort of worked, but then ran up against the way iDVD does presentations. After each slide is presented, the movie 'stops' on that page. You have to press play to go to the next page. Since it stops, the music stops also. So you end up with a soundtrack that is tied to the presentation, rather than one which plays independently. That makes me believe that a fix may be a while in coming, since it's probably going to require redesigning how iDVD creates presentations. However at the very least, iDVD needs to detect linked QuickTime files and handle them correctly."

Audio problem after burned DVD on set top player only?

My burned DVD's play great on any computer PC or MAC but on client's (and mine) set top DVD player the first 3 seconds of the 30-min program don't play any audio???
Client's set top DVD player is brand new and has HDMI out puts, my player is old, 3 years maybe but both players do the exact same thing...the DVD's we're trying to play on the DVD players are all built and burnt from Mac using DVD SP. So the menus all work, even the audio perfectly, but when you choose the program it won't play the audio for 3 sec, then it kicks in, though the video plays perfectly from beginning. I've got 1 sec of Black at the head of program, then it fades up to first shot. I've got that same black slug on both audio tracks for 1 sec as well...tried with and without the black in the audio tracks, no change. Now on a 4 year old Panasonic EM-50 something DVD recorder/player the DVD's did work.
Thoughts?

Hi tomwros
Welcome to apple discussions. Sorry to hear you are having problems navigating a burned disc. In most cases on apple discussions it's the result of the media and not of the hardware / software.
Please tell us which brands you have tried. Include speed of the media itself and if it's plus or minus media. Also when you used Roxio Toast, what speed did you burn at within Toast?

I have Audio problems after 6.1.2 update. What do I do?

Is anybody else having audio problems after updating to 6.1.2? How do I Fix it?

No problems here.
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.

Audio problems from burning DVD's from Macbook Pro?

Hey guys,
So lately I have been having problems with burning DVD. I use either iDVD or Roxio Toast Titanium 11 too burn movies to play on my television. After burnign them I notice all of them have audio problems. It's as if the audio is faint for the dialogue but when background music plays its blaring! I checked my TV and its definitely not my Television because sound plays from both speakers. I was wondering if any other Macbook users had this problem or users of either of these programs had this problem because it's such a hassle burning movies without really enjoying them.
Any help is greatly appreciated!

Audio problems after exporting out of iMovie

Aloha!
I have a 48 minute movie created in imovie with lots of audio, clips and transitions. It works perfectly when I preview or play it in iMovie. When I try to share it to iDvd, export to iDvd, or to save it as a Quicktime movie, it looks great for several minutes, then the audio tracks get messed up. The correct audio is there, but overlayed on it is snippets from farther into the project, or whole tracks from later in the project, or places where the audio drops out completely. I spent about 70 hours creating this movie and really want to burn it to DVD so I can play it on the big screen. I did burn one version to dvd, and it looked and sounded great - until the audio problems began... any help would be greatly appreciated.
In Garage Band there is a feature where you can consolidate your bits into one track - should I be doing something in iMovie after I finish it before I export it?

what kind of speed changes do you mean? If you mean using some clips in slo-mo (with the sound dropped out) then yes I used a LOT of them... but they are also working fine for the first several minutes...

Audio Problems when burning

I have tried making disc image, burning disc and the audio will pause for second several times in the play back. It does not do it when playing back in iDVD.
The slide show was started in iPhoto and sent to iDVD. I have started over several times and still same issue. Makes a bad impression and is really not useable for presentation.
I have 30 gigs free space, changed settings to Professional encoding and still same issue. I have no open apps, changed all energy settings and screen saver to never.
Any ideas, I am fresh out, never had this problem with previous version.
Frustrated

Andy,
This question is really in the wrong place - this is the iDVD '08 forum and not the iDVD 5 forum.
From the description of your problem using Toast, it sounds like you didn't actually export a DV video movie out of iMovie.
Export a DV video movie out of iMovie (it will run 13 GB per hour) and play it back with the QuickTime Player to see if the audio settings you made are really there. If this movie plays OK, you can bring IT into iDVD or Toast for turning it into a DVD.
If the DV video movie you created STILL has audio problems in the QuickTime Player, ask you question about THAT issue in the correct iMovie forum.

IMovie audio problems when burning in Toast 6

Hi,
i've tried to burn an imovie project in idvd 5 but i get 'the error #-1 was reported' like most people have been and i've tried loads of things suggested to fix it with no joy.
I then sent the imovie project to toast titanium 6 where it burned fine. However, when i watched it i noticed that although toast had picked up all the audio (both dv audio and aiff), it did not pick up all the volume adjustments during the movie. how annoying! for example: i have an aiff clip that fades into a movie clip with the sound gradually going down but Toast picks up the sound staying at the same level. this also happens with volume adjustments in a DV file.
Any suggestions why this happens / how i can fix it?
Cheers,
Andy

Audio problems after battery drained

Well, my ipod shuffle 2nd gen was working perfectly well. I'm sorry that I left it completely still in my desk for nearly a month... (No one ever touched it during that month)
After that time, I connected it to my computer, it needed a while (about 5 minutes) before my PC recognized it. iTunes recognized my ipod too, and I can sync music, copy files to and from my ipod. The problem was, when I plugged in the ear-phone, no sound came from my ipod, only some kind of weird noises. At first, I thought it would be my ear-phone's problem, but I tested it carefully with my other Music devices. I'm pretty sure the audio jack had problem, because I could hear disturbed music on my ear-phone. My questions are, why can the audio jack have problem after a month with no-one touch the ipod, and is there any solution for my problems? (I really don't want to use it as a 1GB flash disk...)

what kind of speed changes do you mean? If you mean using some clips in slo-mo (with the sound dropped out) then yes I used a LOT of them... but they are also working fine for the first several minutes...

Audio problem when burning DVD

When I try to burn this with IDVD 5.0.1 everything went well till IDVD has come to the audio part, hereby it goes wrong. I didn't get a failure message but nothing happened further on.
Hope someone has a solution!

Hello, prutgers,
You will need to be a bit more specific with your problem so we can help you.
What do you mean by 'it goes wrong'? What exactly happens?
You need to know that when your DVD is encoding audio, the process appears to be doing nothing. If you leave it alone for a while, it just may finish. Maybe you are not waiting long enough.
Especially if you don't get an error message. What are you doing? Did you force quit? Did the DVD burn and has an audio problem?
Give us more information!

Iphone 4 audio problems after ios6 upgrade

I have problems after upgrade to IOS 6.

DESPERATE, i am back on my laptop with a borrowed charger and i plugged my phone into itunes. It now says i have to restore it back to factory settings. Meaning, i will lose all of my contacts, pictures, etc. because i havn't been able to back it up onto my laptop.
I definitely don't want anything deleted off of my phone. Did any body else have this problem? Is there ANYTHING i can do to refrain from restoring it and losing all of my memory?
Couldn't you have backed it up to the "iCloud"? or some other cloud based storage before you did the upgrade? If you do not back things up before you upgrade your OS, you are only asking for things to go wrong.

24P Audio Problem on burned Disc

I have an asset that was shot and compressed at 23.98. When I bring it in to Studio Pro 4 it plays fine ... audio is synced and all is good. (Although, the inspector says it is a 29.97 file ... I assume this isn't an issue though ... I can confirm that it is compressed at the correct fps.)
Anyway, once I burn the disc the audio seams a hair out of sync with the piece when played on external DVD players ... confirmed on multiple DVD decks. Maddening! Lips don't quite match. What in the heck am I doing wrong?!?!
Thoughts anyone?

Is the audio lagging or in advance right off the bat, and remaining at the same rate of missmatch throughout, or is it slowly going out of sync?
Is the audio AIFF or AC3?
If AIFF, this may be the problem even though the format is in the DVD spec.
Are you viewing on a consumer large screen (42" or larger) LCD or Plasma?
Some displays without lip sync adjustability built-in will pass the audio milliseconds before the video (always before, not after).
Improper lip sync drives me crazy watching network TV.
( and a few commercial DVDs as well)
The standard is too loose.
I use a Felston DD540 to correct the audio on some channels.

Audio popping after burning blu-ray in 5.1

     Just as a disclaimer, I am fairly new to Adobe Premiere and I am running Premiere Elements 8 on a Sony Vaio with an Intel Core i5-580M processor, ATI Mobility Radeon HD 5650 GPU, 8GB DDR3-SDRAM-1066 and Windows 7 Home Premium 64bit.
     I am attempting to create blu-ray disks in full HD and 5.1 surround sound. Source video is full HD 1920x1080 with .M2TS extension. When I have Adobe Premiere Elements 8 check the properties for my videos, it says the source audio format is "48,000Hz - compressed - 6 channels" and the project audio format is "48,000Hz - 32 bit floating point - 6 channels". This is despite the fact that the source should be 5.1. However when editing videos "5.1" shows up next to audio 1 on the timeline. I read something about this issue and I assume this isn't the cause for any poor audio after a blu-ray burn.
      I create new projects using these settings:
               NTSC-AVCHD-Full HD 1080i 30 5.1 Channel
     After some quick editing I burn a blu-ray disk with the H.264 1920x1080i NTSC Dolby preset. When checking the quality of the burn the video looks great, but audio has a distinct popping or crackling occasionally that is not in the source files at all. Anyone have any ideas why a burn causes these audio blemishes to show up? I have never had any issues with 2 channel burns and I will probably just end up sticking with 2 channel audio if a solution can't be discovered. Also of note, the audio output is much lower from the burned copy than it is when played back from the source file. This will happen even when the clip volume is set to the max of +6.0dB. Thanks for any help.

Thanks.
If I play the original mts-file with Media Player Classic, the audio appears 99.9% clean. Using my headphones and 30 second test section, I could locate one barely audible "pop". PrE timeline zoom couldn't show any spikes or anything else suspicious, so I looked into this by extracting audio channels with Mediacoder to wav-file and checking how it looks at Audacity. One channel appeared to have this small step which caused the "pop". This is best described by following picture:
Then, when I export the video (or just audio to wav-file) I get dozens of these similar steps which sound like "pop". Sometimes it is just on one channel, sometimes on both channels. They appear at every 2...3 seconds or so. For comparison, this is how the "pop" looks like when exported from PrE:
Any further suggestions what might cause this increase in "popping" or how to fix it?

Jitter problem after burning DVD from avi or mpeg2 that was exported from original timeline edit

When burning a DVD directly from the timeline in Elements 7, there is usually no problem, however, when first exporting it to an .avi or .mpeg2 file, and then putting that new file back into the timeline, and then burning that new file to a DVD, there is jitter or "strobing" when the subject in the video moves (when playing the DVD).
It's not an install, or re-install issue, because before I started with this new computer, the exact same thing happened with the last computer I was using.
Thanks.

Les,
I do not know the newer Pinnacle Studio products, but going back to 8 and 9, through 9.4.3, the workflow was based on DV-AVI, just like PrE is. Pinnacle might have changed over to MPEG-2 in later versions, but I just do not know, as I have not seen a version, since Studio 10 hit was such a disaster.
One of the problems when working from DVD-Video material is that it has already been compressed to MPEG-2, loosing a good bit of data, and also converting the material to GOP (Group of Pictures), so that individual Frames are not present any longer. This precludes Frame-accurate editing, unless that compressed material is converted to all I-frame. See this ARTICLE for some background on GOP. Then, upon Burn to Disk, that I-frame material is once more compressed (again) to MPEG-2 and GOP for use in a VOB container. This WILL cause degradation of the image, most noticeable where there is motion, either subject, or camera motion. Some NLE's offer what is referred to as "Smart Rendering." This can help in some areas. For portions of the footage, where no changes have been made, beyond just cuts, the material will NOT be Transcoded again to MPEG-2, but will be used, as-is. Note: add a Transition, or a Title, or a PiP, or any Effect, and that footage WILL be Transcoded, so the Smart Rendering aspect will be moot. Sony's Vegas has been recommended for Smart Rendering, but I have never used it. This might be worth investigating. Also, if Pinnacle Studio is working fine, you might want to consider using that program. I have 5 different NLE's on my workstation, and use each for specialized situations, though the vast majority of my editing is done in PrPro.
Regarding the existing DVD-Videos, much depends of the source. PrE can Import and work with 100% DVD-compliant (very important) VOB's. Unfortunately, most DVR's do not create 100% DVD-compliant discs. This is most often manifested in the first VOB, which will contain any Menus and navigation. This ARTICLE will give you some background on VOB's, which are Video Object "containers."
As you point out, there can be issues with the resulting MPEG-2, as it will span part of VOB 1, and then all remaining VOB's. With 100% DVD-compliant VOB's, there will be a perfect flow in the MPEG-2 that spans the multiple VOB's. When the VOB's are not 100% DVD-compliant, issues can arise.
Considering your DVR, it is likely that ripping is going to be the best workflow, as that will strip out the other material in the first VOB and should then gather the data for the spanned MPEG-2. The ultimate rip will be to a DV-AVI Type II file w/ 48KHz 16-bit PCM/WAV Audio. This is an older FAQ Entry from the Encore Forum, on ripping, but might have some useful tips. Note: this was for getting material from a DVD-Video for authoring to a new DVD in Encore, and not editing.
For non-commercial DVD-Video editing, I will use an A-D bridge and my DVD deck, and capture to DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio, and Import the resulting files into PrPro/PrE. This is exactly the same workflow that I use, with analog material, like VHS.
Also note that PrPro, a US$900 program did not get VOB Importing until CS4.2 (current version), while PrE has had it for some time now. Also, PrPro is a DV-AVI-based, I-frame, program, just like PrE, so no "Smart Rendering" there either. Same exact issues exist in "big-brother," PrPro.
Most of all, good luck,
Hunt

Audio problem after rendering!

Hi everyone! I am having a problem with sound in my project after rendering. I am using Adobe Premiere CS2 , and in Audio track 1, I have someone speaking, and in track 2 I have backround music. When I play it back in the window, together it sounds perfect. After rendering, the voice becomes very crackly and distorted. I have tried rendering just the voice without the backround music, and it sounds perfect. It seems the addition of backround music is causing the distortion to the other track. I have tried rendering the backround music seperately and adding it in, but still the problem persists. I adjust the music so that when the kids are talking, the music dips down, and when they are not, I leave it at it's normal level. HELP..I am losing my grip on this one! Thanks so much....Tammy

Tammy,
If we've dropped a bit of time for this part of the edit, you now have time for more fun aspects of it.
While I will casually monitor my Meters, I spend much more time with a good set of noise-canceling headphones, listening critically. The Meters are basically to point up potential issues. With Audio, if you have not invested in a really good set of headphones, do yourself a big favor, and sneak 'em into the budget.
Glad that you got things toned down.
Now, let's go on to Lesson 02 - The Audio Mixer. Unlike adding Keyframes to a Clip, when your cutting is done, you can apply Track Keyframes to attenuate (also Pan, etc.) you Audio Tracks to suit. One would just change the Send in that Track to Write, or Touch, and "ride the gain" with the slider, as is required. I probably do most of my Audio editing there, than addressing the individual Clips. First thing that I have done is cut back a bit on the frequency of the Track Keyframes in Edit>Preferences, as I find the default to add too many (and you can go in and adjust these by hand, if you need to "smooth" things out a bit.). One caution: do this when you are satisfied with the cuts, Clip placement, etc., as these Keyframes are applied to the Track. If you were to remove a Clip, and replace it, those Keyframes would apply to that new Clip, whether you want them to, or not. This trips some folk up, if they do the Audio Mixer thing too soon in the editing. Wait until you are "in love" with your Timeline otherwise. It's like scoring a Project. One does that as about the very last step, or much work will be repeated, and that is not fun.
Good luck,
Hunt

Audio problems after exporting

I have created a 43 minute iMovie with very, very heavy editing.
I love my movie, and until recently, it would play back fine within the application.
(but now, not even this works for me anymore.)
When I export the movie in any format, My audio gets all mixed up.. Random audio clips from other parts of the movie are heard with, or substituted during other parts. It is so frustrating after so much hard work.
Is there any way to resolve this problem without having to start from scratch?

Dito! I just worked for months on 45 min movie and the same problem. And the answer is WHAT?!!!!!!!!!!!!!!!!!!!!!!!!!!!!! whats the piont of beat markers and the ability to use all these things and now i have to WHAT??????? go back and try to re edit the speeds? Great I switched to an Apple only to find out BIG mistake. I cannot believe this has not been fixed. Whata joke! I have to get this DVD in the hands of someone by the end of the weekend that might be able to change my life and i have made a GRAVE mistake in intrusting it in a MAC
