Quicktime mpeg2 - no sound

I recently purchased and downloaded a component Quicktime mpeg2 so that I could play .mpg files on my Mac. When I open these files they now play, but there is no sound. How do I get the sound to play?
Macbook Pro Mac OS X (10.0.x)

Why can I hear and see the apple mpeg2 sample
http://www.info.apple.com/kbnum/n75424-de
but cannot hear anything with my movie?The sample file is a "muxed" MPEG2/MP2 file which is supported by the QT Player when the MPEG-2 component is installed.
What are the differences between QickTime and VLC.VLC is more of a "multi" multimedia player handling "muxed" and interleaved spatially synchronized audio/video data, as well as, QT's temporally "frame-to-framed" synchronized audio and video. In addition, it includes "device encoded" optical output while QT does not.... and so on.
Why it doesn't work with Quicktime inclusive mpeg2 codec?As indicated above, QT w/MPEG-2 component only supports the MPEG2/MP2 (i.e., MPEG-1, layer 2 audio) "muxed" format, elementary M2V video files with corresponding AIFF audio files, and/or custom M2V video track MOV files with QT compatible audio track. The normal solution to your problem is to use MPEG Streamclip (free) to convert your "muxed" audio data to QT compatible MP2 data. (I.e., using the "Convert to MPEG with MP2 audio" File Menu option to change the file to one like the sample file above. This is a very quick conversion since the video data is not changed.)

Quicktime MPEG2 playback component

I've purchased and downloaded Quicktime MPEG2 playback component but I can not openend, the system says that Quicktime MPEG2.dmg is not recognized. Can anybody help me with this issue?. Thanks.

What app are you using to try and mount the image file? The default should be the DiskImageMounter.app application. If it is still the default app, then it sounds like the image file, the mounter app, or your system is corrupted. If not, then make it the default app for the DMG file class.

Bought QuickTime MPEG2 component - "installed" but it's not there

I just bought the MGEG2 component and ran the installer - it said it was going on my hard drive, ran the progress bars, etc., and even gave a nice cheery "installaiton Successful" announcement with an attractive green check mark, Too bad it didn't do jack for QT's ability to open files.
When I look in my (hard drive)/Library/QuickTime/ directory, it's not there.
It should have a resource filenamed "QuickTime MPEG2.component" (everything there is for audio (AC3), Div6, Perian, Flip4Mac and the Save as AVI component from MPEG Streamclip.)
Antbody understand why it's not where it should be?
Reference info:
OS 10.6.7
QT Pro 7.6.6

component installer v. 7.6
(creation date Jan 14, 2009) <- too old?

1) What part of their MP4 doesn't my version of QuickTime understand? (It reads a lot of mpeg-4s, what does it need to know?)
You have two different facets here.
The first is MPEG-4/AVC (H.264) video multiplexed with AC3 audio wrapped in an M2TS, MPG, or MPEG file container. This has many problems. On the one hand the video is MPEG-4 and so the QT MPEG-2 Playback component cannot decode it but it is wrapped in an file container that is basically telling QT to use the QT MPEG-2 Playback component for video playback (i.e., much the same as why VLC considers the content MPEG-1/2 data because that is what both media players expect even though VLC can actually handle the audio and video data in this wrapper). On the other, QT is not natively compatible with AC3 audio and cannot play it natively even if it was able to "demux" the blocks of audio and video data properly and synchronize the two to a common external time reference which is the basis for QT media technology. (I.e., The wrapper being used is based on spatial synchronization of audio and video data interspersed in a single data stream rather than the temporal synchronization of up to 99 parallel data tracks normally used by QT—a basic difference in player technology akin to trying to play a BD disc in a CD player.) Normally, the way around this problem is to use iMovie '08, '09, or '11 to import your content. iMovie contains a special import/converter module to handle this content. Basically, it converts the AVCHD video to AIC (Apple Intermediate Codec), converts the AC3 audio to resampled linear PCM (AIFF) and applies timing offsets as may be needed to ensure synchronization between audio and video content. This data is then wrapped in the generic QT MOV file container making the files compatible with any/all QT based applications. Unfortunately, the special module cannot be used by files already imported to your hard drive at the "Finder" file level.
As to MP4 (SD MPEG-4, Chapter 2) content, these files may or may not be compatible with QT depending on how the audio is encoded, the file container actually used, and/or how your system is actually configured with QT components. In most cases, making the content compatible may be as easy as doing nothing, to changing the file extension or copying the data to a real MOV file container to using MPEG Streamclip to convert/handle the audio content.
2) Why does VLC show the file properties as MPEG-1/2?
Like QT, when VLC sees the wrapper file extension, it "assumes" the file contains a specific type (or range) of data types and reports accordingly. The main difference here, is that VLC can actually play the AVCHD data natively while QT cannot.
By the way the MPEG-2 description jived with a review - CNET, I think - which I'd read online. No doubt this will provoke another one of those explanations that always boil down to "you don't understand, the wrapper isn't telling you what's in the files" responses. Is there a tool for telling what the thing actually is?
Interpretations can sometimes be confusing. HDV content can also be described or reported as MPEG-1/2 content since it is sometimes described as DV100 encoded data wrapped in an MPEG-2 file container. As to what is actually in a file container and utilities to read them, there are a number of such available as free downloads. Unfortunately, many will have the same problem with MPEG/MPG containers if they bother to read them at all but do really well with other file containers. Since most of the content I deal with is MOV, MP4, and/or M4V, I tend to use the free VideSpec and/or Dumpster utilities. In my case I am more worried about MPEG-4 Profiles and Levels, entropy encoding modes, fourCC identifications, key frame frequency, key frame data rates, how the data is distributed between key frames, and the like when trouble shooting problems and most of my dealings with AVCHD are limited to the conversion of DVR/BD content to TV2 compatible content since I don't even own an AVCHD camcorder (and still prefer HDV for editing purposes).
The broader question remains - is QuickTime meant to be general purpose, at least as a player?
No, it isn't. As previously stated, QT technology is based on temporal synchronization of multiple parallel data tracks (up to 99) to a common reference clock and not spatial synchronization by interspersing of blocks of data within a single stream or the interleaving of data frames (which QT can handle because the data is only out of sync by one half-frame per n-1 tracks). This is great if you mask, layer, window, etc. content within a single player but severely limits QT compatibility with older and/or currently competing technologies. In short, pick your player/converter based on the technology used in the source file and not because you think QT should be an all purpose, one size fits all multimedia utility. If FLV Crunch meets your needs, then by all means use it.
I took some similar files I got from a recent model Canon to a video professional's (family) and they couldn't be read by a current version of FinalCut Pro.
Which model Canon? Which "current" version of FCP, the suite or the new FCP X release? Do you have a short snippet you can upload for examination? Have yet to research the pros and cons of the latest release but plan to do so next month if/when I have the time. (I.e., users seem to either really love it or really hate it.)
PC video straightforward, Mac a colossal hassle until you find the right 3rd party application: does that sound wrong to anybody else?
If you opt to use an import work flow that preserves the QT file incompatibilities instead of a work flow that ensures QT playback, conversion, and editing compatibilities, is it the fault of the software or the user?

QuickTime has no sound

After updating to 10.5.1, Quicktime has no sound. At first I thought it was my PBG4. I was able to hear the system sounds as well as iTunes. I recently upgraded Flip4Mac as well. Could this be the cause of my problems. I miss listening to streams via the internet.

Open the Audio MIDI Setup app (Utilities folder) and set the output format to 44100Hz and 16 bit sample size.
Quit and relaunch QuickTime and try the file again.

Purchased Quicktime MPEG2. No audio.

I've just purchased Quicktime MPEG2 playback component for my Mac OS X, and downloaded MPEG Streamclip, and I'm getting no audio from the DVD I imported into imovie. What do I do now?

What content are you trying to play in which application on what operating system? "Muxed" MPEG-2 content imported to iMovie for instance, should now be a MOV file containing all I-frame MPEG-2 video with AC3 audio converted to linear PCM. This file should play in almost any player on the importing system assuming the playing application/system is not muted. On the other hand, "muxed" MPEG-2/AC3 or MPEG-2/PCM content is not normally supported natively by QT (except by Lion and then only in a supported file container) since the MPEG-2 Playback component is a video only codec. MPEG Streamclip should be able to play/demux/convert "muxed" MPEG-2 content and if it doesn't then you may be looking at a more serious or complex problem and will have to provide more information and/or a sample of the problem content for examination/playback comparison on other systems/system configurations.

Quicktime MPEG2 playback broken?

Hello. Suddenly I am not able to watch .mpg files in Quicktime (Macbook Pro) and MPEG Streamclip complains the component is not installed when in fact it is. I ran the installer again, Quicktime MPEG-2 Playback without error. I'm not sure if this problem arose after the QT 7.3.1 update or the last security update. Anyone else?

Quicktime MPEG2 Codec Softward

Just downlaoded Quicktime MPEG2 software which would help convert my .mod files to a usable format in imovie. Paid my S$35 (about US$25) but whehn it was downloafing I got a message saying my Mac OS was too modern for this software!
How can the Apple shop be selling stuff which cannot be used on Lion? Since it is an electronic download there will be no refund and I feel completely ripped off. Any ideas would be really welcome to one very pi**ed off Apple funder.

Whle the Lion installer will not let you install the software automatically because MPEG-2 is already supported for the QT X Player app, the purchased QT MPEG-2 Playback component can still be installed for use by the QT 7 Player and third-party apps like MPEG Streamclip which also rely on your system's codec component configuration. There are several ways to do this
1) You can install the component on an older system and then move the component to the same location on your Lion system.
2) You can use the MPEG Streamclip "helper" app included in the MPEG Streamclip "beta" package to directly install the purchased component package on your Lion system.
3) You can use the Pacifist app to either automatically install the component or extract and manually install the component on your Lion system
4) You can use the system's context menu option to manually open the component package and manually copy the codec componebt to the correct folder on your Lion system.

Quicktime mpeg2

Just purchased and downloaded quicktime mpeg2 on my computer i have a mac os x to view video clips that i imported from my camcord but there is no audio during playback. I have confirmed there is audio on the videos. What can i do to correct this? Please help =]

QT does not support multiplexed MPEG-2/AC3 or multiplexed MPEG-2/PCM files. Use MPEG Streamclip for viewing and/or conversion of such files via the QT MPEG-2 Playback component to QT compatible compression formats. (VLC can also be used for viewing and HandBrake can be used for conversions but neither of these apps require the QT MPEG-2 Playback component.) Import via iMovie '08/'09/'11 automatically converts audio to linear PCM which is also supported by systems having iMovie '08/'09/'11 installed.

Problems operating Quicktime MPEG2 conversion

Hi there,
I have copied my friend's sd card with his movie files which are .MOD and .MOI files which I understand are mpeg2 format. I have therefore downloaded the program "Quicktime MPEG2 conversion for OSX" but cannot see how to use it. I thought that it may have acted as a patch or upgrade with Quicktime but this is not immediately evident.
Would dearly love some help.
Justin

Mpeg 2 is the standard DVD delivery format, not intended for further editing.
You need to convert the mpeg2 files back to DV which iMovie is designed to handle. For that you need mpegStreamclip:
http://www.apple.com/downloads/macosx/video/mpegstreamclip.html
which is free, but you must also have the Apple mpeg2 plugin :
http://www.apple.com/quicktime/mpeg2/
which is a mere $20.

Quicktime mpeg2 plug in

I have an imac 24 and snow leopard is installed, on aplles web site it has a plug-in that allow mpeg2 to be played on quicktime, downloaded it and for a while it worked great. now it will play the mpeg2 but I have not sound. I have video but the volume slider is gone, any other format that is made to play on quicktime normally, plays with sound, but mpeg2 with this plug in will play the video, but no sound any help with this would be great, since this is not a apple product no support is available even though it is on aplle's website and I had to pay apple for it.

If you are referring to the QuickTime MPEG-2 Playback Component ($19.99), then it is an Apple product. It is a video codec only and does not support all forms of "muxed" audio possibilities. There are three like possibilities here:
1) Your movie may contain an unsupported audio format along with the MPEG-2 video,
2) You may have failed to update/install the latest version compatible with your OS, or
3) When you upgraded to Snow Leopard, you may have neglected to install the older, 32-bit version of QT 7.
Therefore, to try and determine where your particular problem lies, please determine:
1) What is audio format and file container type for your problem movie?
2) Do you have the QT 7.6 compatible component installed?
3) Is QT v7.6.3 also installed on your system?

Keynote to quicktime movie no sound?

I have a keynote presentation which consists of several embedded video clips. When playing this presentation live to my class there is no problem at all and everything functions perfectly. When exporting to QuickTime to put on my classroom website, the sound for the first clip will play, but subsequent clips have no sound. Ideas? Alternately i can make a screencast video of the presentation using ScreenFlow and the audio comes through fine, but it requires me to sit and click through the presentation then edit the darned thing. The QuickTime export is automatic, which is really handy. Each video is on its own slide, if that information helps.

I am not running this on an intranet, I am creating a video for my students and posting it to my Internet web page. So if I were to post the keynote file itself, 4/5 of my students would be unable to open it because they don't have Macs. Some do not even have desktop computers and view stuff on their smart phones. I solved the issue, at least partially, by saving the presentation as html and posting it to my site that way. It works but it is a bit buggy. Would still rather make it into a movie.

Quicktime has no sound/audio (probably with 7.1.6 update)

I've tried everything from checking my system preferences, checking up on my quicktime preferences just no longer plays any sound. Can anybody help me? Any comments would be appreciated, from instructing me how to reinstall the software, just anything. Thank you.

Don't know.
When you moved your software was it from a PPC
machine?
You may have moved many non "Intel" components that
could be causing conflicts with your new machine.
Does QuickTime work correctly when run using Rosetta?
yes, migrated from a G4. it sure seems like something like what you suggest is going on. Can you give me more information on using Rosetta? Do you mean running a previous version of QT Player?
my mpeg files run fine on VLC, btw.

QuickTime not recording sound

I'm running OS X 10.8.2 with QuickTime 10.2 and can't get the screen recordings to record audio.
I've tried all of the settings in System Preferences > Sound for both Output and Input and even have Soundlflower installed and have chosen those as options also, but I can't get the audio to record. Or that is... no matter what settings I use for Input... it ONLY records from my 27" iMac's internal microphone.
So... while recording the video that's playing on screen if I talk (to test it) the audio recording of my talking is fine... but no setting will allow me to record what the audio on the video is.
This didn't just begin in 10.8.2... I'm just finally getting around to posting about it because I'd like to occasionally record videos on the screen.
The videos record without a problem.
EDIT: If I select Soundflower (16c) for the Input then the Sound preference pane displays the sound on the video is being recognized by the system (i.e. the Input level shows the bar changing from the audio in the video). But when I play the QT file back... no sound.
Any advice?

I have found a solution to your problem!
I have Logmein installed, and I selected it for the sound output.
I than selected it as the audio source in quicktime and it worked like a charm. I was able to record video with system audio and it was perfect!
I hope this helps!
If @apple is listening tho, There should be an option to select system audio when recording a screen cap with quicktime.

Quicktime no computer sound

How come quicktime can't record computer sounds? Would it be difficult to add this feature to Quicktime?
This feature would really make it an amazing recorder, now its just mediocre use on rare occasion , hey is that quicktime? long time no see app.
It really criples the video recording.

How come quicktime can't record computer sounds?
Because Apple chose not to program the application to have this capability. (My guess is that it would open Apple up to charges by commercial DVD manufacturers of providing a means of pirating copyrighted material by the general public.)
Would it be difficult to add this feature to Quicktime?
It would like be difficult to convince Apple to do this but actually doing so would be simple. In fact, you can do so yourself by installing a module like Soundflower but controlling the audio pipeline would have to be done manually. Some third-party apps use this same approach—even going so far as automating the installation process and controlling the audio pipeline internally. Other third-party apps include their own audio control routines. Basically, you have numerous options ranging from badgering Apple to include such features to installing them yourself to purchasing an application that includes this feature built in, as well as, many others not mentioned.

Quicktime Plays only sound no video

I have had this problem for a while now and never really tried to figure out the problem until now. I just upgraded Quicktime to 7.0 today but I still can't see any video when playing a .MOV file all I get it sound. That goes for if I try to play it in anyother type of player. I have tried to find help but so far I have come up empty. I just want to be able to play .mov files and see video. I hope someone can help me out here thanks.

The first thing I noticed was that you used Microsoft Word to make your Web page code. Bad choice and sloppy code.
Your movies do not "stream" (they download) so the extra hint tracks are a waste of bandwidth and are not needed in the movies.
You are linking directly to the .mov files (also bad). Many computers (PC's) will simply try and download the files. Each movie link should be in it's own html coded page and should have the proper object and embed tags or the QuickTime plug-in may not work. Internet Explorer requires these tags to turn on ActiveX. Many PC users will never be able to see your movies without them.
Last is the fact that you've used the H.264 video codec in the files. This codec requires the viewer to have QuickTime 7 or the Windows Public Preview 3 installed on their computers. This leaves out Windows 95, 98, ME and Mac users running anything under 10.3.9.
Sorry for all the negative news. This is how most of us learned, too.
