IMovie MPEG-2 Muxed audio missing

Audio is missing from your imported Sony DVD Handycam, I have had installed MPEG-2 when importing from iMovie or QuickTime, I still don't get audio.
Can I get a plugin to make muxed audio work..?

Since you have the MPEG-2 component. You can use MpEG-Streamclicp to demux the Mpeg-2...

MPEG-1 MUXED - audio playback disappeared

Hi-
I've got a problem playing MPEG-1 muxed clips, the audio isn't playing back. Happened couple weeks ago, then fixed itself (maybe a codec expiry problem?), now I the sound is dead again, also QT is stalling after 10 secs of video playback..
Here's the details of the clip:
MPEG1 Muxed, 320 x 240
Comp is iMac G5, running Tiger 10.4.3 and QT 7.0.3
thanks in advance for the help!

wow Kirk, thanks for the tip, that fixed he problem strait away-
I'd been searching for awhile, googled, QT help, nothing - I didn't know the MIDI Setup controlled QT playback, and wonder why it changed to 96000 all of a sudden - maybe it changed after I played back a clip with that setting....
anyway, looks like I'll be able to solve that problem in future, its really the only one I've had in years of using QT -
thanks again!

OS 10.4 iMovie exported MP4 files audio missing

Any ideas on audio problem fixes or settings to eliminate?

Are any of the files locked (set to read only) or in use by another application? Do any of them have a question mark displayed when you look at them in the library in the grid view (which indicates they're missing)? Have you tried restarting the computer to see if that helps (sometimes locked files are released on a restart)?

No iMovie Support for MPEG 1 Muxed Video?

When I installed the new iMovie as a part of iLife 08, my iPhoto video's were imported into iMovie...I thought. However, only six of my 400 video clips came across. I called Apple Care and was informed that MPEG 1 Muxed video - the format used by virtually every high end Sony compact digital camera I've owned - is not supported. I was told that, using QuickTime Pro, I could individually convert each video clip in my iPhoto database to MPEG 2 or 4, 4 being the most robust format. That's a major hassle, to say the least. It doesn't seem that Apple would intentionally exclude the video taken by a vast number of iPhoto/iMovie users - Sony camera owners - but it looks like I may be mistaken. Thoughts? ideas? workarounds?

Apple is meant to be about plug it in and work with it, not spend 2 weeks of ** trying to find information on how to do stuff.
What you say is essentially true. However, IMHO there is a reasonable expectation that the item "plugged in" will be of the same form of technology as that into which it is plugged. For instance, I would never expect to "plug" a V2 rocket engine into a 1969 XKE Jaguar in place of the standard 6.2 liter gasoline engine and expect it to simply "work out of the box." Not all video is equal. MPEG-1 and MPEG-2 muxed compression was not invented by Apple, the exclusive right to its use does not belong to Apple, and the spatial synchronization technology involved is different than Apple's own temporal synchronization technology.
How about apple just buy streamclip MPEG and integrate it into imovie 08 so that it is possible for it go say "this is a video I can't work with, please wait a moment whilst I reconvert it for you"... **, why not add it to iPhoto as well, so that it would do it when u add these videos from your camera and avoid the nasty iMovie issues.
Not a bad idea, but who pays for it? First of all, the QT structure does not reside within the applications themselves. They are now a fully integrated part of the operating system. (Ever wonder why you can't "downgrade" a QT update that is causing problems on your system or why people advise that you "wait and see" before installing?) So essentially, the operating system itself, as well as, all sub-systems and applications will have to rewritten, or at least modified, to properly interface with this new "hybrid" engine that you propose that Apple create. And if Apple is to integrate 2-decade old MPEG technology that pre-dates Apple's own technology and which has never been fully supported previously, should they not also include support for similarly aged interleaved compression formats (yet another synchronization technology) which are no longer supported even by their own creators? What about support for other current but proprietary codecs like VidX or WMP? While you may not want all of these different things supported, the man standing next to you probably does.
How much are you willing to pay? Surely Apple is going to pass the cost of research, development, and software maintenance on to the users. Will you spend an extra $225 to $250 to have muxed MPEG, DivX, WMV support "built in?" I'm not. Nor am I willing to foot the bill for outdated/abandoned AVI technology which I don't even use. I personally prefer to embrace the current modular approach and purchase/add only those components which I need on a daily basis but the person down the street doesn't use at all. Call it "freedom of choice" or call me a "cheapskate," but it is the way I feel about the matter. To me, it seems to boil down to a matter of "dollar$ & $ense." (Frankly, I would much prefer that Apple fix the current problems with its own supposedly "fully" supported compression formats before "mucking" about in the back yards of other manufacturers'. Of course, that is only my own personal opinion and I'm sure every reader out there as his or her own agenda here.)
This is not a technical issue. This is a usability issue. i refuse to trawl through my photo collection, re-encode them (even by batch process) and save back to their original locations.
Oh, I can agree that this is a usability issue, but only if "usability" includes the choice of hardware, choice to use/not use it, as well as, the choice to use/not use a workflow that avoids/gets around the problem.
1) If viewing and sharing of files is your only concern, then the choice of camera employing MPEG-1 compression is fine. However, the limited support for this format is well documented and of long standing (although I agree that Apple is not particularly "forthcoming" with that fact that is only "playback" supported).
2) I personally would never use any "still" camera to shoot video clips nor use a video camcorder to shoot "still photos. I.e., you should always use the best tool available for any given job. (E.g., I would not normally us a .22 to go rabbit or dove hunting nor a shotgun to go deer hunting or fishing either.) But, if your MPEG-1 still camera is the only "tool available," then the user must accept the problems that have always accompanied use of partially supported compression formats. (I.e., nothing has changed here.)
3) Am a bit more concerned about those who did their research, picked a camera that supposedly takes "fully" compatible QT video clips, and now find that iMovie '08 will not accept such clips. (E.g., Kodak cameras which take MPEG4/µ-Law clips and even places them in an MOV file container.) Makes me feel almost as if they were somehow cheated. However, at least these individuals can still use iMovie '06 in this case.
4) If you have a viable option that corrects the problem or gets around it and you choose not to use it, then that is a matter of personal choice and one should accept the consequences. Since these files were never audio supported in any iMovie version, I don't really understand why this incompatibility issue is suddenly such a big problem.

IMovie refuses to import Audio MPEG-4 Apple

iMovie refuses to import Audio MPEG-4 Apple files, made with the help of Quick TimePlayer. I had no such a problem even several days before. Recently I upgraded iMovie to 10.0.7.
Is there any way to resolve the problem?

When the import is set to auto I get that same behavior of the infinite loop of trying to import and then rewinding.
A correction to what I wrote before is that it was the top timer that was incrementing not the bottom timer, so that too is the same as what you reported.
Now, uplugging the firewire cable is not working for me.
I'm a new Mac user. I was fed up with buggy windows and windows apps after being a user for 20 years. I made the leap and I'm pretty disappointed. The macpro hardware however is very nice.
I read elsewhere that if you want to capture DV (not HDV) from your
HDV tape you have to do the following in the camera:
1. With firewire disconnected
a. not be in easy mode
b. set "standard set/VCR HDV/DV" to DV (this causes iMovie to set itself into DV mode)
c. set "standard set/i.link conv" to ON (converts HDV to DV on the way out)
2. Connect firewire
3. Run iMovie. iMovie import runs and correctly sees it's receiving DV not HDV
4. At this point the camera is configured as if there were a DV tape not an HDV tape inserted so the camera will not work right unless you now go back to "standard set/VCR HDV/DV" and set it to HDV.
5. Now, if you want to go back to capturing HDV, you have to change the camera settings back, disconnect & reconnect the firewire, and you must exit and re-run iMovie.
This is pretty rediculous, but it works. However none of this seems to affect the capture problem we are having.

No audio playback of MPEG-2 muxed program streams made with Compressor?

Is anyone else experiencing this?
Any fix? Audio plays in VLC so its not operator error..
Upgraded to QT 7.6.6 (1632) and no longer No have audio playback of MPEG-2 muxed program streams made with Compressor?
This machine played audio out of QT with these files prior to upgrade this afternoon.

I've never run a component conflict test is there a tool for that or is this a command in terminal?
There may still be some "tools" around to help with the process but you still have to run playback tests yourself and evaluate the results. The process is quite simple. You just need to "hide" one or more components, open the QT Player, and play a file to see if it is now working correctly. If it isn't, then continue "hiding" additional components. If the file does play correctly, then you have found a conflict and can start "unhiding" components to determine which one (or combination of components) is causing the problem by removing any "problem" components to an external location such as your desktop. Just remember to close the QT Player after each playback test. This is required (or at least used to be required) for the regeneration a new list of components available for use.
I used the term "hide" above since I simply keep a "Disable" folder handy in my Library QT Component folder for just such tests. Placing a component or set of components into the folder temporarily "hides" it from the QT Player when it next generates a list of the components available for use. Specific strategies vary. I sometimes use use a binary tree approach to hide the components (I.e., "hide" half of the components instead of one at a time.) Unfortunately, I don't know exactly how this works with regard to QT X. So, I would likely run such tests in the QT 7 Player. So far, when everything is working correctly in QT 7 Player, QT X seems to be able to play the same file(s) in QT X via the 32-bit switching process.

Audio Missing from Mpeg File

Hi,
I have a Sony DSC-W80 digital camera. I have shot a few video clips that when I preview in the camera have sound but when I transfer them to my computer they seem to loose their audio.
Does anyone know what I am doing wrong? I appreciate your help.
thanks,

I have a Sony DSC-W80 digital camera. I have shot a few video clips that when I preview in the camera have sound but when I transfer them to my computer they seem to loose their audio. Does anyone know what I am doing wrong?
How are you "transferring" the file to your computer. Sounds as if you are performing some sort of conversion as part of the process. MPEG-1 muxed files are normally "playback" only compatible with QT/QT applications. That is, you should be able to play them (assuming they are reasonably standard in nature, don't contain timecode breaks, and are properly terminated) but any attempt to convert them using QT structures will lose the audio. Can you post a sample of one of your files for testing?
If you are converting the files, then that is your problem. To retain the audio content you must use an MPEG-based, third-party conversion application like MPEG Streamclip (free). iSquint (free), FFmpegX (donationware), Visual Hub (payware), etc.

Mpeg with mp2 audio

I am getting ready to deliver TV spots for air via FTP, and the media house requests the video be delivered as mpeg with mp2 audio. Maybe I'm missing something, but I couldn't figure out how to do that easily through Compresser, or even through Mpeg Streamclip.
Here's what I wound up doing: I exported the spot as uncompressed Quicktime. I brought it into Compressor and encoded it as mpeg2, Best Quality and the audio as Dolby 2.0 (in the future, I'll just use AIFF). THEN I brought those files into DVDSP in order to mux them, then opened the resulting VOB in Mpeg Streamclip and converted it to mpeg with mp2 audio.
That seemed to satisfy the tech guy at the media distribution house. But there's gotta be an easier way, right? I know I'm missing something simple...

It's been a while since I've done it with MPEG Streamclip, and I'm not at my Mac right now ... but as I recall, both the audio and video files need to be in the same folder and have the same name (except for the extension). Bring the video file into MPEG Streamclip and it will automatically find the associated audio file.

Mpeg 1 muxed to mpeg4 NO SOUND!!!

I am trying, without success, to create a movie with IMovie using some existing Q-time mpegs that are in mpeg1 muxed format (first time trying to do this...) - BUT! - the muxed audio will not export to mpeg4. No sound. Nada. The Quicktime "Help" has been unhelpful in resolving this. Suggestions?

QuickTime Pro has never been able to export audio from "muxed" files (MPEG 1 or 2 and Flash).
Use MPEG Streamclip (free) to either export or convert your .mpg files to QT formats.

MPEG 1 Muxed

I have no idea what 'MPEG 1 Muxed' is but i am having trouble burning this format on iMovie. Is it a supported file type? It plays fine on my computer and plays fine when I do the preview but after I burn it will not play the audio (video is fine). the audio is from the movie and i am not trying to add audio from a different source.
if it is not supported- is there a converter that i can get to make it work?
thank you

.AVI is just a file 'wrapper' that contains content encoded in various ways. In general, .AVI isn't a good 'format' to use with Macs. You'll be better off with a .MOV file.
In addition, MPEG 1 muxed files are often reduced in image size so the quality may be limited.

Audio missing when shared to QT

Hi,
I've shared a 52minute movie original in iM6HD to QuickTime and on two occasions the audio is completely missing in the resulting .mov (and also a .wmv version I made).
This is a pain as it takes hours to save to QT.
Where am I going wrong, guys?
TT

Your audio settings may have been changed.
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.

Alternatively, if the audio was from copy-protected tracks from iTunes, they won't copy over. If that is the case post back for a workaround.

Audio missing from video recording.

I recorded some camp footage with a canon rebel T2i. there is audio when i play the clip in imovie timline, but when i export it there are peices of the audio missing. I have removed the clip and re-uploaded it several times and the audio is still missing in the same places. Im not sure if maybe i have the setting wrong or if maybe the file from my camera is corrupted.

Same problem with me and it seems a lot more users. Audio and Video are playing fine in other players and other types of video, everything is connected as it should. You would think that something major like this would not get past quality control before it's being released. I'm getting more and more agitated as there has been absolutely no mention of this from Apple, yet this seems to be a wide spread and major problem. I bought Season 1 of The Office tonight and it is rendered useless because audio won't play, and the DRM limits how you can view your videos.

Audio Missing From My QuickTime

I have a Sony CyberShot camera and, I hooked it up to the computer and, I draged my movie clip from my camera to iMove HD then I saw that the format is in MPEG-1. iMove doesn't have sound for this type of fromat. Is there some way I can change the format so I have the sound? Thanks!

I converted it to MPEG with MP2 Audio and I did convert to MPEG and I am still not getting sound which format do I need to?
The MPEG Streamclip "Export to DV" option will create an NTSC or PAL standard 4:3 or 16:9 aspect ratio file that will be compatible with any current version of the iMovie editor. (In fact, selecting the 2 GB segment option will make these files compatible with the earliest versions of iMovie.) If you are using iMovie '08, then DV/DV, DV/Linear PCM, AIC/Linear PCM, MJPEG/AAC, MJPEG/Linear PCM, MPEG4/AAC, and H.264/AAC, etc. files would all be acceptable/editable. At least one individual has reported problems using Photo-JPEG video, but I have not had any problems personally. However, avoid the Apple Animation and Apple Video compression formats. (These files will import and edit, but there is a "bug" in export that either limits the video data below that needed to render more than a "black" display or simply renders a "black" screen that in turn drops the video data rate. In either case you won't get any video output.)

Thanks for all this information, T.
So why are you editing a 1440x1080 video in a 1920x1080 project? If this is AVCHD footage, it's very important to use the right project settings.
That has no effect on your audio, of course. But it could affect your video quality when you output your file.
That say, can you explain what you mean by "Audio missing from save project"?
Do you mean that you don't hear the audio in Premiere Elements -- or that you don't hear it when you output, say, an MOV or WMV file?
What file format are you exporting and what are you playing soundless this file on?
And, finally, is there no audio whatsoever, or is only some audio (music, for instance) missing from your output?

MUXing audio & video streams into one .mpg file

Hi,
Anyone had any luck using DVD Studio Pro or Compressor to take a video and audio stream and combine them into one finished MPEG 2 file sutable for use on an MPEG server? I need to do that and haven't found a way with either program to MUX audio and video together.

Build your DVD. Each track will be a different VOB in the Video_TS folder. menus in VTS0[1]0.VOB where the [1] changes based on VOB, video/audio starts with VTS0[1]1.VOB
They will be in the order they appear in the track layout in DVD SP (unless you change them in VTS view in DVD SP 4+) If there is alot of material you will see
VTS0[1]1.VOB
VTS0[1]2.VOB
etc.
Open the appropriate VOB in MPEGSTREAMCLIP
