Loss of audio on burned DVDs

Hi,
I have a friend's homemade dvd of a German TV program and wanted to extract parts out of it and burn as my own DVD. I used Handbrake to extract the VOB files as mpeg4 files, then used MPEG Streamclip to combine the files as one 40 minute mpeg4. I then used iDVD (on my MacBook Pro, using 10.5) to burn a DVD. The DVD now works fine on the MacBook Pro, but when I try to view it on my standalone DVD player, I get video but no sound.
In the past, I have successfully used this same procedure a number of times with no problem. I'm not sure why I'm getting stuck here.
I've now tried importing all the mpeg4 videos into iMovie and have sent the one iMovie file I created to the Media Browser. I then burned that file using iDVD. The same problem reoccurs. I get video and sound when I play the DVD on a computer, but I get only video when I use my standalone DVD player. I can get a faint audio if I turn the tv sound way up, but its very faint. The video picture, however, is fine.
I never had this "no audio" problem with any of the other DVDs I burned using iDVD.
Any ideas on how I can get my audio to play when using a standalone player?

I had a similar problem a few years ago. At that time I was using a MOTU 828. That particular model has since been superseded.
What happened was that everything worked correctly for the first hour-&-a-half. After that, I lost all audio. Eventually, I worked out that the MOTU had an intermittent fault. Since changing my audio interface, I've had no problems like that.
I hesitate to suggest the MOTU is at fault, but if all else fails, have it examined by a specialist repairman just in case.
Good luck with your search for a solution.

No audio on burned DVD

I have used I-movie 6.0.3 to create a movie including added an audio track brought in from Itunes, so MP3 files. I then brought it to I-DVD 6.0.4 to burn and saved as a disc image to check it. The disc image looks and sounds correct, but when I burn it to a disc and try to play on either a DVD player or on a computer there is no sound.
Any ideas on what to do?

Hi
Any idea ? - Yes, iTunes Copyright mechanism.
In iTunes - copy out the needed audio as an Audio CD .aiff
Now Use this in iMovie.
The re-edited movie will now work with iDVD and even better so if You DON'T use the
Share/Export to iDVD function in iMovie.
• Just close iMovie
• Open iDVD
• Import Your movie project (Icon with a Star on it)
∆ Now iDVD will do the rendering and so much better.
Save as a DiskImage
Test this with Apple DVD-player
Burn it with Apple Disk Util tool (or rather if You bought it : Roxio Toast™) AND AT x1 speed.
This is important though it gives far less errors (speed can't be set in iDVD 6 - it reads speed from
DVD disc)
I use only Verbatim
I use DVD-R (no +R or +/-RW)

No Audio upon burning dvd-R on 2.8 Ghz imac running 10.5.5 and idvd 7.0.2

I am able to import clips into idvd that have been declared shared in imovie. I am able to create a menu and have multiple video clips on the screen. The clips even play fine (with audio) when previewed.
However once I burn to a dvd-R and play back on any dvd player I get NO SOUND! The only sound I was able to get was the sound of one of those themes in Version 7.0 that come with built in music.
The actual video clip however has NO AUDIO. What is going on??? I tried a new idvd project etc but still no luck.
Any help, much appreciated.
Thanks,
Vidur Sood

Hi
As above.
But if You want to squees in eg 3hour on a standard 4.7Gb DVD disk.
One way is to use Roxio Toast™ and the function put in the movie anyhow.
This will do the work but to a rather reduced quality.
There are other programs that can do this too but Toast™ does it as good as
one can anticipate and to a fair price.
Alt. DVD Studio Pro in FinalCutStudio bundle
ForMac Devideon™ but then You'll buy an extra DVD-burner too. (not sold separately
as I'm aware of)

Windows DVD Maker: no audio on burned dvd

I burned a movie using Windows DVD Maker, the playback video is fine but there is no audio. Audio is good on original AVI format of the movie but I get no audio when I burn it to a dvd using the Windows DVD Maker. I have an HP G60-445DX notebook pc, Windows 7 32bit Sevice Pack 1installed. Any help would be appreciated, thanks.

Hi akanyr,
Welcome to the HP Forums! I see that you are having problems with your audio. I have done some research and I have a link for you that has a few steps to try. Step 2 mentions installing the latest audio driver and I have the link below for that. Step 4 in the document suggests a different DVD burner and then has a link for their burner. I don't recommend that program one way or the other but there are several DVD burning programs out there.

Do not want dual audio after burning dvd

I have .avi movie with two different languages and after burning are both in movie while playing. I would like to set only one language before burning it with iDVD. Thanks

Hi
I think You support to little info.
• .avi is no Codec but just a container - so what's in it ?
• iDVD has just a few video codec that it accepts
• there are no multilingual funcion in iDVD - so each language has to be it's own free movie (will take up no: x places eg three movies = three times more space needed)
So may be I'm not really understanding Your problem - so Please Re-Phrase and add more info and step by step description on how You try to do this.

No audio from movie on the burned DVD

This is the 5th DVD I've made with the "Chapters" Theme on IDVD 6. All 5 were created as movies from various clips in IMovie and shared with IDVD. The other 4 came out fine, but on this 5th one, everything works fine on the computer in IMovie and IDVD, but when I burn the DVD, there is no audio on the movie. There is audio on all 3 menus, but when I click on the button, no sound on the actual movie. I've read quite a few of the discussions regarding audio problems, but most seem to be regarding loss of audio on menus or slideshows. In a response regarding these menu problems, someone referred to a muted sound icon. I can't find any audio icons for the actual movie. I've been working on this for over a week. Would really appreciate some help. Thanks.

Hi
May be this applies ?
*No audio on DVD disc.*
Most common origin:
1 Imported audio from iTunes:
• In iTunes copy out as an audio-CD .aiff
• Use this in Your movie project
2 Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
Before burning the DVD:
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If OK:
• Make Your DVD - or -
• Burn from DiskImage with Apple Disk Util tool - and at an as slow speed as possibly eg x1
• OR burn with Roxio Toast™ if You got it

MPEG4 Movie audio does not end up on burned DVD

When I create a DVD in iMovie, the audio for the MP4 movies does no end up on the DVD. However it is audible in iMovie prior to creating the DVD. The movies were created with a sony camera mpeg4 format. I do not understand why they play in iMovie but not on the burned DVD?? Help.

When in iDVD, use the Delete Encoded Assetts in the Advanced menu. This often clears up any garbage left laying around.
Also my standard list of things to do first for these weird sort of problems, but I also tend to run these before I go to burn an iDVD project just to be safe. Keep in mind this list represents the programs I tend to use. I am running Panther (10.3.9) so Tiger users might want to check the below list for compatibility. There are several alternate programs that do the same things with some combining the functions of some of the ones below. So everyone has their favorites, but here are mine...
Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system, especially any external drives that you use for iMovie and iDVD projects.
Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
Run Cache Out X (free download) to clear all system and application caches.
Reboot your Mac (after running Cache Out X you are given the option to restart the machine).
If you still can not get it to run correctly, next thing to try is to throw out the iDVD preference file (don't forget to change back those preferences you want different from the defaults next time you run it).

Has anybody actually succeeded in burning 96/24 audio onto a DVD-R?

Has anybody actually succeeded in burning 96/24 audio onto a DVD-R and been able to play it back on a standard DVD player? iDVD apparently does not support 96/24 audio files. On three different computers, 2 MacBooks and a G4 Powerbook, with 5 different versions of OS 10.4.11 to 10.5.8 and several different updates to Toast 9, I still have never been able to burn a 96/24 Music DVD. 48/24 works, but that throws away half the musical information/resolution--and that really isn't satisfactory. Is there anyone out there who has actually succeeded in burning 96/24 Music DVDs with Toast Titanium 9???? If so on what machine and with what OS (and I suppose what version of Toast 9)? Any hints? Thanks

Try having a read of some of the articles on this page. These cover the use of the Burn folder as already mentioned as well as various other methods.

IDVD 6, no audio on disk image or burned DVD

Seems I've just been plagued with this problem as well, and the first time I noticed it was after accepting an upgrade from iDVD 6.02 to iDVD 6.04 as well as a firmware update.
Audio from imported .avi files plays fine in the iDVD preview and even played perfectly on disk images and burned DVDs, but now there is only audio in the video I dropped into a background drop zone, and no audio in the two movies. During a second burn, still no audio in the movies but audio for the first 5 seconds of the loop of the background movie. I should mention, prior to updating, these .avi files were burned perfectly. So this is very erratic.
I used appzapper to remove iDVD 6.04 and reinstalled 6.02, but the problem persists. I'm wondering *if any others have experienced the same issue after some form of "upgrade"*. If there was only some way to revert back to the old firmware I would. A few other updates took place as well, but I can't remember exactly what was done.
Quite ridiculous for updates which are supposed so solve issues, just create them.
Any new fixes for this apparently popular problem? Is there a way to revert back to my old firmware?

Have you updated to QuickTime 7.1.2?
Suggest you create a disc image and then burn the DVD. File/Save as Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

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 from one clip plays in preview, not on burned DVD

Have just completed burning a DVD of a 23-minute movie. Everything works fine except that the audio associated with one clip in the movie is almost non-existent. If I turn up the volume when playing the burned DVD through my DVD player/television, the sound can be heard, but barely. The audio from that portion of the movie plays normally while previewing and editing in Premiere Pro, it plays fine as a WAV file in Encore, and it plays fine in Windows Media Player. However, various attempt to burn that segment onto DVD, either alone or as part of the assembled movie, produce almost no sound. Again, the audio for the entire movie is perfect when played in Premiere Pro or Encore; the audio is also perfect on the burned DVD except for the one troublesome clip, in which the audio is so faint that it can't really be heard.

Dan,
Can't thank you enough for taking the time to hazard a guess about my problem.
I'm a real newbie with regard to video editing, so not conversant with much of the language, but all of the movie's clips were recorded in 16-bit stereo and the resulting DVD was played back through my television, which is a widescreen playing through its own speakers. I think the pertinent information, however, is that everything in the movie plays perfectly with the exception of this one clip, which was produced in exactly the same way as the rest of the movie. The one difference is that we used a different microphone for this clip. But again, this clip, like the rest of movie, plays fine when being previewed in the computer. Go figure.

Apack sounds fine - Simulator/burned DVD definite audio pumping

Can't understand why after many days research/testing/fiddling I cannot seem to get the AC3 audio to play cleanly in DVD SP 2 simulator or when burnt to DVD...the FCP 4.5 audio is set between -12 and -6 (peaks), export as aiff files, compress in Apack at 192 kbs, stereo, -31 dialnorm (return entered), sounds great/fine when played back in Apack...import into DVD SP 2 and there is definite gain pumping or whatever one calls it throughout some tracks. Host will be speaking, at certain points, the volume will rise up, then the level will dip down for a second or two, then rise back up a bit even increasing the background hiss just a bit, then remain constant for a while, then rise up/down again...at least this always happens in the same places.
Wonder why only in DVD SP/burned DVD does this happen, and how does one overcome this? Very annoying.
Thanks much

Just to be sure - are you hearing this in DVD Player or on a set top player?
If you look in the DVD Player preferences, have you got the disable dolby dynamic range compression checked or unchecked?
If unchecked, this can give you the same effect as you describe... so try checking it and playing the disc again.

Gaps in audio when burning on dvds and cd

When I burn a dvd and add audio, I have gaps in the playback on the audio only.

Hello BCRC,
What make / model computer are you using?
What operating system?
What program are you using to burn the DVD's and CDs?
By gaps are you meaning that there is a gap from one track to the next and you are looking to burn gapless discs, or are you referring to the audio actually skipping parts of the audio when burning?

Trouble encoding audio when burning to dvd

I have finished editing a nearly 2-hour long wedding video and all is going well, everything encodes fine until....it comes to my audio. I have now tried to burn this movie 7 times to dvd and EVERY time it freezes when it reaches the stage of encoding the audio. Any tips?
Message was edited by: Bri

Hello, trouble,
Welcome to the discussions. Sorry you are having so much trouble burning your DVD. What exactly do you see when you think it is freezing? Does it just look as if nothing is happening? Do you actually get a message that says there is a problem with the burn?
If you are using any version of iDVD prior to iDVD 8, I suspect that your audio is encoding fine and not really 'freezing'. It will LOOK as if everything has stopped, because the those versions did not include a 'time remaining' notice. You can see a small thumbnail of the menus encoding, and you can see the video of your movie as the video encodes, but when audio encoding is occurring, there is only a black square. Depending on your computer system, the process can take some time. I recommend that you just leave it alone, maybe overnight, and see if it is fine in the morning. On my older iMac, a nearly 2hr movie might take over 12 hours to finish encoding/burning.
I do recommend that do a 'save as disk image' for every iDVD project.
If you are not familiar with this process, it is the creation of a file that is an exact replica of your iDVD project. The encoding looks the same as it is occurring, but the end result is a disk image file, not a burned DVD disk. There are several reasons to do this: It can save you from wasting disks if there is something wrong that prevents a successful burn; you can view your disk image on your computer using the application DVD Player to view your project and see if it is ok; you can use the disk image for burning disks through Disk Utility (or Toast); and you can control the burn speed--should be 4x or less.
And, you now have a self-contained image file that you can save and from which you can burn disks in the future. Because it is self-contained, you can safely delete your iMovie and iDVD projects, thus saving drive space. Even though you can burn another DVD using one that you already have burned, the disk image file is a better backup. DVD disks can crack, break, melt, etc. and if you lose your copy, you will not be able to burn another.

No audio when burning a DVD from iMovie to iDVD

Hope someone can help me here, I'm not getting any audio on the DVD I've burnt even though it's working fine in the preview screen on my desktop. Even the audio from the theme I've chosen isn't coming through.
I'm using iMovie HD 5.0.2 and iDVD 5.0.1

even though it's working fine in the preview screen on my desktop.
You can't really depend on the preview function to pick up problems with a burn. That is the reason that saving to disc image is recommended. If that works, then the burned DVD will be ok.
