Nero MP4 audio problem

I have a number of MP4 audio files created using Nero 6. With the recent upgrade of iTunes, the program now interprets them as video. The screen turns black and the sound quality is extremely bad. Besides converting the format, is there a way to coax iTunes to play them as pure audio like the older version did. I have a new x-fi soundcard but I don't think this is the problem because they play fine in other audio applications.
Hope someone here can help, and thanks in advance for any advice offered.

Rename 'em to M4A files. This usually works.
Failing that, load the files up in foobar and use the "Optimize MP4/M4A" function on them. This sometimes helps.

Playing mp4 audio gives error message "Video can't be played because the file is corrupt"

Playing a particular mp4 audio file directly from a website link gives error message "Video can't be played because the file is corrupt". However other mp4 audio files from this same website do work correctly. What can I do to get all the the mp4 audio files to play directly from the same website? I must have the correct plugins, etc. since the other files play. This file is not playing from YouTube, is it on the website.
Thank you for your help.

What is the link to the site and file in question?
MP4 files should be handled by Firefox itself, not a plug-in.
# Click the ≡ Menu Button and choose Add-ons.
# Click Plugins.
# Set every plug-in to "Never Activate".
# Try loading the file again. Is there any difference?

How to play mp4 audio files as video on my iPod Touch?

I know you are all thinking that this is a stupid question based on the topic, but I have videos for some reason that are in the form of mp4 audio, but they are video when I play them on my computer. I can open these videos (mp4 audio instead of mp4 video) using Windows Media Player and it's not just audio, there is also video. However, whenever I try to sync it to my iPod, it shows up in my music section instead of videos. If i play the video under music, all I see is the white iTunes background, no video. Is there anyway for me to set these files to be recognized as video and store it under my movies category?
Thanks.

First, go into Get Info and change the Media Kind on the Options tab to tell iTunes that this is a video. Next, you need to sync this item from the Video tab on your iPod detail in iTunes (i.e. don't sync it as if it was a Music item). If you sync all video content then this will happen automatically once you change the Media Kind. But if you only sync part of your video library, make sure you include this video in the sync selection.
If you still have problems, you may need to convert the video for iPod playback, even if it plays fine in iTunes. If that's the case, right-click on the video and you'll see an option to convert for iPod use, which will make a copy (so make sure you know which version to sync to the iPod, or simply delete the original).

Premier Elements 8 Audio Problem

I just got a new Dell laptop last week that came with the Adobe Photoshop Elements 8 and Premier Elements 8 bundle pre-installed.   I’ve never worked with Premier Elements before and thought I’d try my luck with it yesterday. I edited several movie clips that were taken with my Sony camera in MP4 format, joined the clips into one movie with transitions between them, and rendered the finished product in .mpg format.
The video plays fine in all programs, but the audio is a different story. It is silent in Windows Media Player and Real Player, yet plays well in Windows Media Center and Windows Movie Maker. It also plays on my Dell PC in Windows Media Player (the same program that silences it on my Dell laptop).
I'm a senior citizen and have worked a little bit with Windows Movie Maker but that is all - nothing more intricate than that program. I’d like to burn my new movie file to DVD but would first like to know what is causing the audio problem. I'm hoping it's something simple and that this aged brain can understand the "fix". Any suggestions?
Thank you for any help you can offer me.
Anne

Hello Hunt, and thank you for helping me.
Yes, you have described the problem correctly. In PrElements, all was
well with video and audio - and still is OK in two of the video players I have
on this new laptop.   However, there is no audio in the other two programs
- but only on this Dell laptop in Windows Media Player. There IS audio in
Windows Media Player on my Dell PC. That's what really confuses me.
Yes, the original file from the camera was mp4 and was exported as mpg
(MPEG). I don't remember the settings I used; I think the only thing I
changed was a quality setting. Is there a way of going back and looking at the
original settings to jot down what they were?
I think that the free version of Real Player has improved over the years
and has a few more "goodies" now than it did in previous editions.   For one,
I was able to capture an internet video in its entirety last year, and
very easily. I wanted this video (a show trailer) for a slideshow I was
creating and couldn't figure out how to get it with any other application.
That's the main reason I installed Real Player last week on this new laptop -
"just in case" I want to do this again.
I will take your advice and look into the two free players...
And, in response to your second post, WMM has given me a good start but,
unless I'm missing something, it does not have the capability of burning a
DVD. I will check out the resources link and the Training Series that you
describe, and thank you so much for your help!
Cordially,
Anne

Anne,
Welcome to the forum.
Just to make sure that I am following you, I will restate what I think you
are experiencing, and then please correct me. Along the way will be a few
questions too.
You have created a Project in PrElements, and have Imported Video (with
Audio) into the PrE Project. The files from your Sony are in MP4 format.
In PrE you have your Audio, correct?
You have then Exported/Shared that Project to an AV file as an MPEG. Do
you recall the settings chosen for that MPEG?
That Exported/Shared file plays with Audio in some players, but in others
it only plays the Video, but not the Audio. Is that correct?
Knowing the settings used to create that MPEG file might explain why some
player software does a good job, where other players have an issue.
This is an aside comment - I find that WMP, especially the later versions,
is not a good choice for a player. It seems that MicroSooft has done as
much as possible to strip it of most capabilities. Instead, I recommend two
free players,
http://gofree.com/download/Video/Media-Players/vlcmediaplayer.php?gclid=CLW6soS44KkCFQoBbA odO3L2Xg and
http://mpc-hc.sourceforge.net/. Both are excellent, and will play files, that some other players struggle
with. Again, both are free. Because all players are not created equal, I
just go with what works. If you were distributing these files to a client,
that was locked into WMP, especially the newer versions, then addressing the
issue would be worth the detective work. If that was the case, then I
would explore Exporting/Sharing to WMV format, rather than the MPEG.
I have not used RealPlayer in about a decade. I found it to be nearly
useless then, and rather ill-behaved. I will not let it near my computers,
though it has possibly been improved over the years. If you have any RealMedia,
MediaPlayer Classic HC, can be modified with a free plug-in, to allow
that. If you do not have RealMedia files (usually designated by .RM), then I
would not worry about taht. Only install what you need, when you need it. I
would just ignore RealPlayer, since it is installed.
Good luck, and hope that this was helpful. Let us know a bit more about
the MPEG settings, please.

Audio problem when importing video files.

Hello everyone,
I just started using FCP X a few days ago for a university project and I seem to encounter an audio problem when importing videos in .mp4, .mov format or via the import from camera option.
Indeed I need to import videos in .mp4 and .mov format into FCP X. The import in itself is normal I can see my videos into the events/clips library and if I play them from the library I can hear the sound quite perfectly.
However, when I want to edit my videos and put it in the timeline, there is no audio. As a result I started to think that my videos could be the problem so I tried the option "import from camera" option using the Isight camera of my macbook pro but the same things happened. I could hear the sound from the events/clips library but not from the timeline (I can't see any audiowaves in the timeline).
I found a solution using quicktime and extracting the audio of the video in .m4a then importing the videos files and the audi files corresponding but it's a long process and a waste of time as FCP X should be able to import the audio of my video into the timeline directly. Especially if it can read it from events/clips library.
I hope I explained myself clearly and you could help me resolve my problem.
Cheers
Christophe
PS: I'm using FCP X version 10.0

Update to 10.0.5.
You have an incorrect setting when you edit. Try trashing your preferences. Post screen shots of your timeline and toolbar.

Audio problems when exporting files from Premiere Pro CS5

I try to post in English.
I have audio problems in Premiere Pro CS5 when exporting a film.
I cut an interview. The sound seems not to be synchronized when exporting a file. It doesn´t matter what file format I export. On cutting points the sound is different to the sound I hear in premiere. In premiere the audio sounds very good but in exported file I hear cracks on cutting points.
When I reimport the audio file an put it in the timeline the synch point is correct but the interview differs about 2 frames to the original audio in premiere.
The material was filmed on Sony ex3. The files are XDCam HD. I have updated the production suite.
Thanks for answers
Frieder

Also, make sure that you check the box marked "Export Audio" if you want a MP4 extension.

Audio Problem since upgrading to Mountain Lion

Has anyone encountered audio problems with their iMac? I just upgraded to Mountain Lion on my i7 27" with 16GB of Ram and found that the Audio starts to get distorted and eventually cuts out after about an hour! It starts cutting in and out when I move the mouse and eventually there will be no sound at all!
Sometimes it can take over an hour of steady use, my last time was watching a movie on Netflix. I initially noticed this using a USB DAC Headphone Amp.
I never had any Audio problems before, my machine is over 1 year old.
I enjoy watching movies in iTunes and DVDs, but this is making it difficult! A full restart usually fixes the problem for a time but it will eventually come back
I'm seriously thinking of going back to Lion for the time being and seeing if it is a Hardware problem.

i don't know if mine is the same issue, but i had no sound through any of my applications after upgrading to mountain lion. here is what i had to do to fix it:
-- applications > utilities > audio midi setup > UNmute all options under "built-in output" (they were mysteriously muted)
Also, I noticed that the options for "use this device for sound output" and "play alerts & sound effects through this device" were no longer assigned to my Built-in Output device. They were assigned to some other random sound driver. To fix, i right-clicked on Built-in Output and reassigned those items to my built in speakers. All fixed now!
very weird problem, though.

Can Apple fix the 12 bit audio problem once and for all?

I have had persistent audio problems from I Life V3 all the way up to I Life 06. Sometimes it is synch issues. Sometimes it is audio dropping out. I have been through the various forums and applied the various remedies with some successs, some failure. The basic problem is that I have an extensive quantity of Mini DV tapes dating back to 1997, most recorded with 12 bit sound (prior to 2002). Apple's basic stance has been, you must use 16 bit sound or I Movie and/or I DVD won't work and . And proposes awkward workarounds. Basically placing the onus on it's own consumers. Why can't 12 bit sound support be included in I DVD 06 and these persistent audio issues put to rest once and for all? Is there some overwhelming technical reason why it cannot be done?

I don't know about overwhelming, but the DVD specification (which was not developed by Apple) calls for the audio to be sampled at 16-bit/48KHz (I think you might also be able to use 96KHz as well). This is what the software expects. If you choose to use another sample rate then the software may or may not be able to "fix" it in post. The real problem is that many camcorder manufactures set the audio to 12-bit by default.

HOW TO FIX NO AUDIO PROBLEM IN FLASH (4 SOLUTIONS)

This solution is for WINDOWS ONLY!!! Unfortunately I believe
it is a bug in flash itself as I have read more than one instance
of this same no audio problem occuring on MAC'S and LINUX based
systems as well. IF YOU KNOW OF SOLUTIONS TO THE MAC OR LINUX BASED
PROBLEMS, PLEASE POST THEM IN THIS THREAD.
Description of the problem: Video sites such as YouTube,
VideoSift, Break, Google Videos, Yahoo, and a plethora of others do
not stream embedded audio. Viewing a YouTube video, for example, on
VideoSift.com results in the video playing back with no audio.
However, by going directly to YouTube and playing back the same
video, it appears to work.
THERE ARE SEVERAL POSSIBLE SOLUTIONS.
Problem: You may be missing your WAVEMAPPER driver.
Cause: Wavemapper driver was removed during installation or
updating of the Flash Player. It might not necessarily be Flash
that removes it but apparently something does.
Solution #1: Google "Flash No Audio WAVEMAPPER" for
directions, its been covered a bunch, but basically requires
running REGEDIT and readding the WAVEMAPPER key to the appropriate
location and value in the registry. Its not as difficult as it
sounds.
http://weyland.be/wrdprss/index.php/2006/08/22/no-sound-in-macromedia-flash-player-9/
if your wavemapper key is installed correctly...
Possible Cause: Corrupted or damaged flash content preventing
audio streaming from working correctly.
Soltuion #2: Run CC Cleaner and delete only cached Flash
content. It is a free program, again just google "download CC
Cleaner". This particular solution worked for me.
If CC Cleaner also does not work, the description of your
problem may differ slightly. In my case on several computers, one
day it worked, the next day it didnt. If it never worked, this
would be a logical solution for you. One variation of this that I
have found is to create a new Windows User Account and log into it.
The reason the CC Cleaner method may work better is that the User
Accounts have their own separate cache folders so a corrupted cache
preventing audio playback on one profile will not be available on
the other User Account to cause the same problem. I wont explain
how to do this as the CC Cleaner will work better but if you are
curious, yet again google "create new windows user accounts". I
have also seen this method work on one of my affected computers but
it did not fix the issue on the account I was having problems with.
http://www.ccleaner.com Install
and run it, use it only to remove Flash under the Applications Tab,
Multimedia, Adobe Flash Player. Check it and uncheck everything
else, then hit Analyze then Run Cleaner.
Possible Cause: Missing Codec
Solution #2: Download and install the K-Lite Codec pack.
Again, google it. A CODEC stands for COmpressor DECompressor and is
a way to make audio and video files small enough to be transferred
on the internet. There are a lot of different codecs and if you
want to play back a video that was compressed using a particular
codec, you will need that same corresponding codec to decompress
your media source and view its content. Basically if you dont have
a codec, you cant observe the content of the media. If you have a
VCR and want to play back a DVD, you are out of luck unless you get
a DVD Player. DivX and XVid Codecs are some of the very popular
codecs used on the net, but to get those, I still suggest getting
the K-Lite Codec Pack.
http://www.free-codecs.com/download/K_Lite_Codec_Pack.htm
Solution #4: Go back to Flash 7. If it aint broke dont fix
it. This Final alternative is only to be used as a last resort.
You'll have to get rid of Flash 9 and go back to Flash 7. The
really tricky part here is that you have to prevent Flash from auto
updating itself. If you install Flash 7, and hit up YouTube, you'll
immediately get Flash 9+ installed again with the same problems. So
AFTER you uninstall Flash 9 (use Macromedias / Adobes uninstaller,
yet again go google it) make a new text file and name it MMS.CFG,
in the file put this one line "AutoUpdateDisable=1" (without the
quotes) and put it in BOTH your c:\windows\system32 AND
c:\windows\system32\Macromed\Flash folders. This will prevent flash
from Auto Updating to 9+, then have to find some place to download
the old flash 7 installer. I found one here.
http://www.intercomm.com/downloads/Flash7.
Only problem is that most sites will try to make you install Flash
9 and Flash 7 does not work on all sites, but it does on some like
YouTube. DO NOT UPDATE TO FLASH 9+ IF YOU USE THIS METHOD.
You will probably want to IMMEDIATELY go to
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager05.htm l
after installing Flash 7 and UNCHECK the update feature
I've tried to write this quick little guide at 3AM so Im not
going to take more time to research other ways to fix this problem.
If you have other solutions, such as for MAC and LINUX, or feel
like adding on to something else that I've written here (links
would be useful to the downloads I suggested) or correcting any
mistakes I probably have made, please say so.
One of these solutions is bound to help you. Theres multiple
causes for this no audio problem so there is obviously multiple
fixes.

Audio Problems in Adobe Presenter: Help Needed Urgently!!

I am using trial versions of Adobe Presenter 7 and Adobe Connect 8.
I created a presentation in in Powerpoint 2002 and published through Adobe Presenter to Adobe Connect Pro. This presentation has voice over recorded through the Adobe Presenter "record audio" option.
In Adobe Connect Pro, I created a meeting and shared the above mentioned presentation through the "Share Document" option in Connect Pro.
Now, when I play the presentation in this Adobe Connect Meeting, I am not getting any audio that was recorded in Adobe Presenter. Whereas if I play the published presentation directly it plays the recorded audio.
Can anyone help me on this?
1. Are there any settings to be done in Powerpoint or Adobe Presenter or Connect pro?
2. Is it the problem of Trial Account or something like that?
Please let me know the solution. Need to work on this ASAP!!!
Thanks in Advance,
Yogini

This is a weird one. If you created a prezo with audio and published it to AC (Adobe Connect) and everything worked fine on your desktop then it should work fine in AC i.e. there are no other settings required on AC's side, it should just play.
As I am typing this I thought of similar audio problems that we have experienced in the past. A big one would be where another user created a PPT on their laptops and handed it to us. When testing the audio did not work. Reason being is that not all the files were coppied over BUT I must accept that this is not your problem as it definately worked on your PC before you published it to AC.
Wait there is one setting in the publish settings. In the output options tick "Upload source presentation with assests", then tick audio.
I cannot think of anything else. There is a man called Heyward Drummond on the Adobe Connect General forum, who is a real master at answering queries like this. Why not post your query there and see if he comes up with an answer?

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
