No sound on mpeg files

I can't get my quicktime pro to play the sound from mpeg files

We need more information to help you.
Have these MPEG files been "exported"?
Do you get any sound from .mov files? Do Web files (trailers) work?

No sound from MPEG files

when streaming mpeg files through the internet, or even dragging mpeg files onto iTunes, there seems to be no sound. However, when viewing wmv files, there is no problem. Does anyone know of any downloads or quick cures for this problem???

Hi Jak-E and Welcome to the Apple Discussion Forums
<<AAC-encoded files rival the quality of audio CDs, and sound as good as or better than MP3 files encoded at the same or even a higher bit rate. For example, a 128 Kbps AAC file should sound as good as or better than a 160 Kbps MP3 file. Because the bit rate is lower, the AAC file will also be smaller than the MP3 file. AAC files enable you to store the most music on your hard disk or iPod. You can fit the same number of songs on an audio CD using Apple Lossless, AIFF, or WAV; the song files are smallest with the Apple Lossless encoder.>>
MP3 files can be fairly large. Make certain you have at least 15% free internal hard drive space. Go to iTunes/Preferences/Advanced and make sure you have your sound preferences set appropriately.
Choosing MP3 custom import settings
If you use MP3 encoding, you can use custom settings for greater control over the quality and size of imported files.
To use custom settings with MP3 encoding:
Choose iTunes > Preferences, click Advanced, and then click Importing.
Choose MP3 Encoder from the Import Using pop-up menu.
Choose Custom from the Setting pop-up menu.
In the dialog that appears, choose settings:
Stereo Bit Rate: The higher the Mono or Stereo kilobits per second (Kbps), the higher the audio quality and the larger the file size. The most common bit rate for stereo MP3 files is between 128 Kbps and 192 Kbps. Lower bit rates are more appropriate for sound files containing voice recordings (as opposed to music).
Variable Bit Rate Encoding (VBR): This setting varies the number of bits used to store the music depending on the complexity of the music. This can help keep file size to a minimum.
Sample Rate: The number of times per second that the music waveforms are captured digitally. The higher the sample rate, the higher the quality and the larger the file size. Don't choose a sample rate higher than the rate used originally to store the music or you'll waste space. CD quality, for example, is 44.100 kHz, so choosing a higher rate when you're encoding from a CD is unnecessary. In general, the best choice is Auto, which uses the same rate as the original music.
Channels: If you don't have stereo speakers or if your audio files are monaural, choose.Mono (mono files are about half the size of stereo files). If you'll be listening to your MP3 files using your stereo system, choose Stereo or Auto. Auto converts tracks that are already monaural into mono MP3 files, and stereo tracks into stereo MP3 files.
Stereo Mode: In Normal mode, your MP3 files contain one track for the right stereo channel and one track for the left. In many cases, the two channels contain related information. In Joint Stereo mode, one channel carries the information that's identical on both channels, and the other channel carries the unique information. At bit rates of 160 Kbps and below, this can improve the sound quality of your converted audio.
Smart Encoding Adjustments: Select to have iTunes analyze your encoding settings and music source, and then adjust settings to maximize quality.
Filter Frequencies Below 10 Hz: Filtering inaudible frequencies results in smaller, more efficient files without perceptible loss of quality.
And... post your query in the iTunes forum here: http://www.apple.com/support/itunes/
Importing songs from the Internet
You can add audio files that you find on the Internet to your iTunes library.
Important: Don't steal music. Some websites require you to register before you can play or download files.
To download a song from a website into iTunes:
Open iTunes.
When you find an audio file you want on a website, click the file to download it to your computer.
Drag the file to the iTunes window.
Some websites permit you to download the actual audio file. On other websites, the download is a link (the URL) to the audio file; when you play it, iTunes finds the song on the Internet and "streams" it live to your computer. This kind of file displays a broadcast symbol (shown above) next to the song in iTunes.
When you buy songs from the iTunes Store, the files are downloaded to your hard disk and automatically added to your iTunes library.

Exported MPEG file to iPod, but there is no sound...

I purchased Quicktime Pro and read all the information on how to export a video file so that it plays on my iPod. I waited the 8-10 or so hours for it to export, and when I tried to play it back there was no sound for that file.
HOW CAN I FIX THAT???

QuickTime Pro doesn't export audio from muxed track files. You found that out.
You'll need other software to either export your MPEG-1 file to iPod specs or to QuickTime formats.
Check in the iPod forums. You'll find lots of Windows software discussed.

No sound when playing mpeg files

I can't get quicktime to play sound when I try to play videos that are mpeg files. I already downloaded mpeg-2 playback as well as Perian 1.0 but it still won't play sound. Any suggestions?

To Apple Discussions!
Solution
1. Open Audio MIDI Setup (/Applications/Utilities/), then check the Audio Output setting.
2. Change the Audio Output setting to 44100.0 Hz.
3. Quit Audio MIDI Setup.
KB article - No sound from some applications, but system alert sounds play (Mac OS X 10.3, 10.4)
Another trick: If you have GarageBand installed, open it (maybe open a GarageBand document) and then quit out of the application.

Emailing mpeg files only do sound. No video.

When I attach mpeg file for emailing it only sends the sound. I open the original fine and it is ok. But when I open the just emailed it is only sound. I have W7, and use Windows Media Player. Video is small file (11 sec) and 3 mb.

Open the file with QuickTime and then open the Movie Inspector window to find out what codecs are used.
Search (Google) for that codec.

No Sound when converting MPEG file to MOV - Quicktime Pro

Hi Everyone,
Just got my first Mac (MacBook Pro) which I love but I'm having a problems importing MPEG 4 files from my Sony digital camera. They play fine through quicktime in the sony format but when I import into quicktime (or imovie for that matter) then export in a .mov file all the sound is lost.
I see some people have reported problems with sound similar to mine but none appear to be the same?
Any ideas??
Many Thanks
Wes
Ps Running all the latest updates..

I am having a similar problem and I see this was never persued any further. I am trying to convert an mpeg file to a mov file using quicktime pro. When I do there is no sound.
Movie info for mov file is: Format is H.264 Decoder, 320 x 240, Millions, FPS is 15, Data Rate is 256.21 kbits/sec.
Any help would be greatly appreciated. I'm new to quicktime and frustrated from spending hours trying to figure this out! Thanks in advance!

Quick time v.7.1.3 play mpeg files without sound

From day to an other day, I dont know why, but quick time stop to produce sound and it is affect too the player of Itunes. It is the same effect for all my mpeg files.
My mpeg, codec MPEG1 muxed, files look ok because mplayer OSX play them correctly.

Hi! I'm having a similar issue. Also on QT 7.1.3 and the latest Flip4WMV, all of the sudden a couple of days ago I lost audio on my MPEG files. In addition, when the video first starts, it pauses for 0.5-2s and then starts playing. The audio indicators at the bottom show a quick spike and then nothing.
I opened the Audio MIDI Setup and under the Audio Output section is says Output Is Not Supported! I also tried the Garageband trick and it does not work.
WMV and MP4 video play just fine. It's only regular MPEG files (I assume MPEG-1 and MPEG-2). And all my files play just fine in VLC and MPlayer2.
Any help would be appreciated.
TIA
Curt

HELP....AVCHD / MPEG files not playing correctly!

I have been trying to download video that was shot with the new Sony FS100 camera that I'm told are AVCHD or MPEG files to my older Adobe Premiere Pro 1.5 timeline, but they are not playing correctly. When I reverse the field dominance, the image plays better but the sound is strange (I was able to speed the sound to 450% and it worked better, but then the balance of the sound from the clip is lost somewhere.).
Any suggestions to make these files play and work correctly? I tried converting them to AVI files but that showed up completely black on the timeline! Anything I've tried either affects the video or audio negatively! I try either makes the image play or stutterThis was shot in regular SD format, NOT HD, so they should be able to play on a standard timeline. Can anyone suggest anything to help please? Much appreciated!

Thanks for your reply, I ran it through Media Info. Here are the results:
Container & general information:
MPEG-PS: 290 Mib 4min22s
1 Video stream: MPEG video
1 Audio stream: AC-3
First Video Stream:
8833 Kbps, 720*480 (4:3), at 29.970 fps, MPEG video (NTSC) (version 2) (Main@main) (Custom Matrix BVOP)
First Audio Stream:
256 Kpbs, 48.0 Khz, 16 bits, 2 channels, AC-3 (DVD-Video)
Please let me know where to go from here. Thanks so much!

Running 10.6.8; Quicktime Player 10.0; No sound on MPEG

I have an MPEG file created a few days ago which I know runs on Ubuntu Linux. It's a little over 2.0 GB in length. I tried to view this on my iMac, which is runing 10.6.8, and was instructed to purchase a plug-in for Quicktime movies. Okay. I don't like, but I do it. Now, the Quicktime player comes up, and the video plays but NO sound.
I checked the obvious places... This is very frustrating because I need to transcribe this sesssion and I'd rather do it here than on my Ubuntu laptop. It's a good thing that I keep a working version of Linux around ... I suppose. Does anyone, anywhere have any idea of what magic needs to happen to rectify this situation
TR

I may be mistaken, but I believe you need to have the MPEG2 Playback Component installed for Quicktime to work with MPEG in SL (it is included in Lion). I purchased it a long time ago from the Apple Store (not app store) for less than $20 - a quick download.

What software do i need to play sound for MPEG-1 Muxed or MPEG-2 Muxed?

i converted one of my video files
but it only plays the vidoe but no sound.
according to "article" on this webpage,
I need speical software to play sounds for
MPEG-1 Muxed or MPEG-2 Muxed files.
WHAT SOFTWARE DO INEED?!
Please and thank you

Hello!!
Actually, you need Oracle Spatial or Oracle Locator. Oracle Locator is free on Oracle Express, and you could start with it. Otherwise, if you want to know more, Oracle Spatial comes with Oracle Enterprise, and Oracle 10g gives you a schema that allow you to store, manage and query spatial data through Oracle functions, etc.
To start using MapViewer, considering that you already have some spatial data stored on the database, you could download the MapViewer kit at http://www.oracle.com/technology/products/spatial/index.html.
You could buy the Pro Oracle Spatial book. It´s very good.
Good Luck!

How can i convert MPEG file to midi or wav format

Hi,
Can any one help me in converting MPEG music file to midi or wav format.
I am trying to import it to my 3D application to run my animation but have to convert it to midi or wav format.
Can anyone help me please. Audition can do this job ?
Steve

For a start, MIDI isn't a sound format, so you can't possibly convert mpeg to that. All MIDI is is a way of sending note-on, note-off, etc information. It stands for Musical Instrument Digital Interface - gives you a bit of a clue, really...
Audition will automatically convert any file it can open to wav (that's how it works), but since you haven't said what sort of mpeg file it is (and this is significant), we can't tell you any more until you do.

Premiere CS3 and mpeg files

Befor to install the CS3 version of Premier, I would know if Premiere to recognize mpeg files or must rendering it (so Premiere Pro 2)
Thanks.

Based on reading a LOT of problem reports, importing files from a DVD camcorder or other MPEG device, or Ripping DVD files rarely results in success in Premiere... do not be fooled by movie industry advertising into thinking that "DVD Quality Video" is suitable for EDITING... it is not... a DVD is designed to be for PLAYBACK only... and that includes trying to edit a Standard Def MPEG or VOB file!
You should also use WAV sound files, not the compressed MP3 format, To work with AC3 files in Premiere, it MAY work to copy the ad2ac3dec.dll file from the Encore DVD directory into the Premiere directory
Go to my notes page http://www.pacifier.com/~jtsmith/ADOBE.HTM
Click the internal link for editing compressed files... read
There are other products better suited to your task... but if you only have DVD type files, you should convert to DV AVI... go to the VideoHelp link in my notes and look for a program to convert
The only SD (Standard Def) files that Premiere really likes are DV AVI type 2

How can I get Safari (on Mac) to play MPEG files on my website?

We have lots of media files and I want to play these files on Safari (on Mac) with QuickTime plug-in or VLC Web plug-in or anyting else...
These files' properties:
Extension: mpg
Video codec: MPEG Video (PAL) (Version 1)
Audio codec: MPEG Audio (Version 1) (Layer 2)
Multiplexed (muxed)
I tried QuickTime plug-in but it does not support the auido codec so the media file was shown with no sound. After a little research I found "QuickTime MPEG-2 Playback Component" which supports MPEG Audio Layer 2. But it is not free... (I have not tried it, maybe it won't work...)
After that I wanted to try "VLC Web plugin for Intel Mac" but it did not work on my Safari. I heard that this project has not developed for 3 years...
Is there any way to get Safari to play MPEG files?
Note: No, I can not change media files' codec...

If the pages load on one network but not on another, then it's a network problem. Try restarting the hotspot.

Computer Generated frames at HD resolution result in mpeg files skipping

I'm trying to make a computer animation, frames generated as jpegs in 3D Studio Max at 1280 x 720 pixels. With video only, I can use the Adobe Media Exporter to make an Mpeg 2 file which plays without problem, however as soon as I add music the mpeg file skips, both sound and picture. I've tried using both an wma and a wav file, and made sure the audio settings in the Exporter match (bitrate, Hz etc). Any suggestions would be gratefully received.

> Microsoft's own Windows Media Encoder 9 Series
The encoder does a great job of encoding, but I HATE the interface. It is horrible and slow and has no batch capabilities.
However, if you also download the Windows Media Encoder 9 Series SDK from Microsoft, it includes this file:
\WMEncSDK9\samples\vb\batcher\BatchEncode.exe
It is supposed to be a "sample" of an interlface you can make with Visual Basic -- but it's a fully functional front end for batch processing to .wmv. Now THAT is cool :)

Problems with (a) import of .MPEG files (b) HDV material /tape

I have issues several issues with *Final Cut Express 4.0* and iMovie '09 which might be related. Basically the *import of HDV material* seems to be impossible, at least with the camera I use. I really hope this is not the case!
I currently try to convert from the Windows environment to Mac. On my Windows Vista system I use Premiere Elements 7 as a default software for video manipulation. The *HDV camera* I use is a tape based *HV-20 from Canon*. The import on the Windows system is done be a 4-pin to 4-pin Firewire cable which worked fine. The result is a file in format .mpeg.
When I try to import tapes on the iMac I firstly discovered - a new cable is required. The iMac uses the 9-pin Firewire 800. So I have this cable. However it seems this does not solve the issue. *Neither Quicktime nor iMovie nor Final Cut Express 4.0 can even recognize the HV-20 camera from Canon.* What could be the reason? (remember the same camera setting is recognized by the windows system).
Secondly I have issues in transferring my collection of .mpeg files to the iMac. Here I found out a mpeg-codec exists for Quicktime (applicable from Quicktime 7 onwards). This codec needs to be bought separately - however it didn't help in this case. Quicktime recognize now the .mpeg file but the screen remained black and the sound is silence. So, *how can I import .mpeg files into Final Cut Express 4.0*?
I seek for some good advice here. Hope somebody can help. Thanks.

Hi(Bonjour)!
Welcome to the forum.
You have to select Apple Intermediate Codec 1080i60 in easy setup dialog to capture from this camera.
No need of MPEG quicktime component at this stage. HDV is transcoded to AIC.
Here's an example of workflow when working with HDV material edited in HD sequence:
It's a must to use the correct setup in easy setup dialog to fit your shooted material on tape.
Here's the steps to follow if you want to edit in HD (by the way some camcorders can shoot in HD mode or DV NTSC mode: wide or standard screen (or pal for european model).
On the FX1
-find the camera menu and set the recording format to HDV (it sould be 1080i60 (1080i50 for FX1E model)as it's the HDV format used by this model).
-Set the output format to automatic or 1080i (this is the type of signal that will be outputed by your camcorder upon capture via firewire).
-turn off you camcorder and mac.
-Plug both devices with a firewire cable.
-turn on the FX1 AND the mac.
-Start FCE
In Final Cut Express 4.0.1
-Use "Easy Setup..." command in Final Cut express menu , select HD in format tab, 29.97 in rate tab and HDV-Apple Intermediate Codec 1080i60 (or AIC 1080i50 for european models). Click "Setup" button.
-From this point, any new sequences and capture session will occur in Apple Intermediate Codec 1080i60 (the format used to edit in HDV).
-Use command-8 to open the capture window. HDV is captured via a simple dialog. There are no capture settings or log clips info.
-Start your camcorder in *VCR mode*(the play button on camcorder or on remote) and click the capture now button into FCE HD.
NOTES: there is no sound from your MAC upon capturing. There is a lag time between what is played on your cam and what you can see on your mac screen, so use the camcorder screen to monitor the content.
-Hit the "ESC" key when you want to stop the capturing process.
Once the esc key is pressed, your mac will continue to process the captured material and the capture window should close.
