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,

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.

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?

Why is audio missing from movie

why is audio missing from movie

I think I may have confused you a little bit, sorry. Hope this might be easier to follow.
1. Copied nieces VHS tape to DVD discs. Tape runs approximately 2hr. 39min.
2. Put first part on work copy 1. This consisted of the lead up to the ceremony and the ceremony itself, ending with still shots of the wedding party, in the park. About 1hr. 1min.
3. Put second part on work copy 2. This consisted of the wedding reception, beginning to end. About 1hr 38min. No possibility of overlapping content.
4. Ran both work copy 1 and work copy 2 on the VCR that's hooked up to the TV. (Not the Toshiba copy machine). Both ran through, beginning to end with no glitches.
5. Opened Adobe Premiere Elements and loaded work copy #1 so as to make three finished copies, one for bride and groom, one for bride's parents, one for groom's parents.
6. When placed on the timeline, contents of work copy 1 had no audio for VTS_01_1.VOB while VTS_01_2.VOB and VTS_01_3.VOB were whole.
7. Tried for several days to eliminate the problem with no success. A.P.E. showed file sizes of .99GB, .99GB and 47MB respectively. The 47MB is actually about 2 minutes of still pictures of       the wedding party. I was not going to attempt to burn the project until correcting the audio problem.
8. Wrote in to the community forum and happily received your response. Tried every thing you offered without success. Though I am thankful for all your time and effort. While nothing worked       so far, I have learned a few things and will retain my notes so as to keep this information at hand. (Don't know how you're able to maintain all that info).
9. At this point, in view of the results of step #4, I thought to try Windows DVD Maker to see what developed. Loaded work copy 1 into that program, which recognized the audio in the first clip       (VTS_01_1.VOB). I did not run the work copy, beginning to end, in this program. But I felt that as long as the audio was present in the first clip, this program would allow me to burn the           copy. When the burn button was pushed, I received the error message "Will Not Fit", and the duration of 30 min for clip 1, 30 min. for clip 2 and 25 hours and 30 min. for clip 3. Clip 3 being       the 2 minutes of still pictures. After trying unsuccessfully to remedy this problem it was time to try a different approach.
10. Opened A.P.E. and loaded work copy 2 onto the timeline. Successfully made three finished copies of this disk in a short period of time.
11. Took the VHS tape back to the Toshiba to make another copy (work copy 1A) of the first segment.
12. Played copy 1A in the TVs VCR and it played fine, no glitches.
13. Opened A.P.E. and put work copy 1A on the Timeline. This time there was audio in clip 1, which could be seen on the audio line, but it was the audio from work copy 2. This, even though       I had deleted the files from work copy 2.
14. Accepted the fact that this has become a career. Can't imagine what you're thinking. Since beginning this endeavor I have become much older and grouchier. My dog will no longer walk         with me. Neighbors go back in the house when they see me coming. Oh, and my wife sticks out her tongue and makes funny noises whenever I turn my back.

Class file missing from war file deployment

I have a web application that is being deployed to a war file. I have deployed several times successfully. Then with the latest changes, there is a class file that does not get included into the war file. It does get compiled and does exist in the project directory.
The class file is in a seperate project from the project where the war file deployment profile is; however both projects are in the same workspace.
There are several other classes in the project that contains the missing class file that does get included in the war file. I don't see anywhere in the profile where these files are selected individually.
I'm at a loss as to how to fix this problem other than add the file after deployment.
Appreciate any help or ideas...

"Could not get the audio data from the file" error

Hi
I get a lot of "Could not get the audio data from the file" errors when opening a project. Sometimes they crash Premiere Pro CC 7.01 (Mac). But if not Premiere works as usual, with the audio.
I tried to convert the audio files (coming from Audition) from 32 to 16 bit. It worked while opening a project once, but not the following times.
Where can it come from ?
Edit: I also get this error when importing audio: "Error: Premiere Pro version 7.0 is not compatible with the Premiere Pro Plug-in version 5.7.4". Maybe it is connected.

Got it! It was the Smartsound plugin making trouble. Got rid of it and no more errors.

PPro CS4 - half of audio is missing from exported files

Hi all.
I'm currently working on a project in PPro CS4, and by that I mean that I've already completed the project. It was exported and uploaded to youtube for my boss, no problems. Then he asked me to combine the two videos, so I copied the second half of the video and pasted it onto the first half's sequence. The settings I used for the two sequences were the same. When I play the video in PPro everything works fine. When I export the video, however, the audio is missing from the second half of the video (the half I copied). The second half audio is on the same track as the first half of the audio, so the audio levels on the exported video should be exactly the same.
I've been browsing the forums and looking at troubleshooting pages but I still haven't found a solution to the problem. The video is intact; only the second half of the audio is missing. I have no idea why it's doing this or how to fix it.
I'd appreciate any input.
-RD

Yes, if he is exporting one file of video and audio then either the entire track is exported
or only the work area bar is exported for both video and audio. If he is exporting video and audio separately THEN they might be different lengths.
You might right-click the audio for the second section and select Audio to see if it is muted.
Try exporting the audio alone without video, listen to the audio in Windows Medica player and listen if all or only half of it exported. If all of it exported, then that narrows the problem.
You might try creating a new Sequence and pasting the video and audio into the new Sequence (don't just duplicate the sequence, that may just duplicate the problem). Then export and see if that circumvented the problem.
What format are you exporting to?

Some Audio Missing from Exported Movie

I've exported a movie from iMovie to iTunes for sharing with AppleTV but the sound is missing from the last 75% of the movie when played back in Itunes or AppleTV. All the sound is ok in the iMovie project so some of it appears to have gone missing when exporting to iTunes.
I have tried re-exporting it but it's still the same result.
Any help would be appreciated.
Regards
Joe

Like everyone else here, I'm just an iMovie user who volunteers to help answer questions.
Unfortunately, recent changes to the Discussion software introduced bugs that make it very difficult to reply to user questions. Despite assurances by Forum administrators, these bugs are not being fixed.
This is to ask that you contact Apple, suggesting that additional resources be allocated to fixing the Discussion software. Hopefully your support will encourage Apple to address these problems.
Here's the man who should be able to get some action:
Steve Jobs <[email protected]>
I plan to include this message in postings until the issues are resolved.
Joe, I've also seen problems exporting iMovie projects with the Apple TV exporter, although never the problem you mentioned.
I suggest you try another way to configure your own export settings. Your goal will be to create an export very similar to Apple TV, but build it on your own. The Apple TV exporter uses the H.264 codec, used for many other exports too.
(You can test this on one or two clips in the affected area before exporting the entire iMovie project. Use the "Share selected clips only" checkbox.)
Instead of choosing the Apple TV export in the export dialog window, try choosing "Movie to MPEG-4". Then click on the Options button. Configure these settings:
UNDER THE VIDEO TAB:
Video Format: H.264
Data Rate: 2653
Optimized for: Download
Image Size: Custom, 720x480
Frame Rate: Current (or 29.97 for NTSC, 25 for PAL)
UNDER THE AUDIO TAB:
Audio Format: AACV-LC (Music)
Data Rate: 128 kbps
Channels: Stereo
Output Sample Rate: Recommended
Encoding Quality: Better
When the export is done, change the file extension to ".m4v", the extension used by Apple TV, if you like. You'll want to test the movie in whatever ways you now use the traditional Apple TV movie.

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.

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.

Failing to add audio track on mpeg file

Hi and thanks for all good answers the recent days. I'm a new and happy user of PRE8. I'm just about to finish an hour long movie. This is when a serious problem occurs in adding the last movie material to work with.
All thru the project I've added mpeg files without any problems. (Yes I have now started to import these files as AVI with a much better result (less stress on the process) as I have been told to do here). The way I have done this is to add the mpeg files, then saved them for personal computer as AVI and opened them in a new project, cutted them finished and opened them in the original main project file. This has worked well.
But the very last mpeg file I am going to add came into PRE project without it's audio track. The audio track exists. It plays in media player. But does not join the video track into PRE.
Is the only solution here to import the file from the camera-dvd?
Best regards, kjetil, norway

Use Windows Movie Maker or Prism outside of PE to first convert the suspect file to DV-AVI.
See the FAQ on where to get Prism, WMM should also be on your system, or can be found at www.microsoft.com:
http://forums.adobe.com/thread/415317?tstart=0
Once converted, test file outside PE and make sure it plays okay.
Then import the DV-AVI into PE.
This might get you to the promised land...

Music is missing from Media files

So I have many CD's I have copied to iTunes. I copied them years ago. I'm now trying to copy some of the music files from media to my phone (non-Apple) which requires me to do it from the media file location on my windows.
I noticed music is missing from my music on iTunes. I have not found a way to update/backup whatever to get the missing music to the media files?

"Not sure how or what caused the Compilations folder in the file path."
iTunes will put any songs for which the "Part of a Compilation" flag is set into the Compilations folder. Unless you have an older type of iDevice there's really no need to ever use "Part of a Compilation" (and even if you do, its only necessary for "Various Artists" compilations). In this example, if you select the album in iTunes, right-click > Get Info > Summary tab and set Part of a Compilation to "No" (and assuming that you have configured iTunes to manage your library) the media will be moved to C:\Users\RS Desktop\Music\iTunes\iTunes Media\Music\.38 Special\Flashback_ The Best of .38 Special.
"So after I moved a few songs over, went to iTunes to play. It says it can't locate the songs."
Ah, that may be the problem ... based on what you're reporting you have these two options set under Edit > Preferences > Advanced:
This means that iTunes determines where to store media based on Artist and Album information - if you start moving files around yourself it will inevitably lose track of it (indeed, iTunes lacks any capability to keep track of media when moved by anything else, irrespective of its settings).
"How do if I click on a song a pop up asks if I want to locate, then I can go to the media files folder and get the song, but that if individually."
iTunes does sometimes automatically fix related links when you do this - however, it can't be guaranteed to do so and there is no "bulk fix" capability built into iTunes itself.
If possible, restore your iTunes Media using a backup taken before you started moving files around. Turingtest2 has a useful script (http://samsoft.org.uk/iTunes/scripts.asp#FindTracks) that may help to resolve further issues (as always, before you start running any scripts that may modify the content of your library take a backup first).

CS4 MacOS X update to 4.0.1 No audio in imported MPEG files (AC3)

After update my Premiere Pro MacOS X to 4.0.1 ver,
no audio in impoted MPEG-2 (*.mpg) files whith AC3 audio.
How to install AC3 codec to Adobe Premiere in Mac Os X ???
I have installed AC3 codec (AC3 Codec 0.4 component) in folders:
system/library/QuickTime
system/library/Components
library/Components
library/QuickTime
but this does not solve the problem.

Was the 4.01 update supposed to add AC3 editing capability, something Premiere has traditionally not had in the past? I thought it was only supposed to add AC3
export capability (seeing as AC3 is a delivery format, and not a good choice for editing).

Tips for Users with Audio Issues in MPEG Files

I have seen a lot of users expressing issues with getting audio to export correctly in their videos, and I thought I would share what's worked for me.
Whenever I'm converting MPEG videos, I have found it useful to open the video with an audio editor (I use GoldWave) and export the audio as a WAVE file. I can then open that WAVE file in QuickTime, copy it to the clipboard, and choose the "Add to Movie" option in the player with the video. Once that's done I'm able to export the video along with the audio.
For DVD's with Dolby Digital audio, I've had success with DVD2AVI. Using that program I can decode the Dolby Digital audio to a WAVE file and use the same method of opening it in QuickTime and choosing the "Add to Movie" option. This has proven invaluable for transferring videos captured with my DVD recorder.
Basically, my solution has always been to extract the audio as a separate WAVE file and adding it to the video using the "Add to Movie" option.

I have sensory issues involving bright lights, flashing lights, loud noises, high-pitched noises, proprioception, and some other stuff. I don't have colorblindness.
I also have a fix to use bigger font sizes to reduce eyestrain. I tried using zoom, but too many websites broke with zoom, it kept reverting, etc. If nosquint does zoom better than the default, nosquint might help with that.
But... I still have sensory issues involving bright lights, flashing lights, loud noises, high-pitched noises, and a lot of other stuff everywhere and online, and I still need fixes ...and I also need people to stop beating me to the ground, but that's beyond Firefox.

Apps missing from itunes file

My iTunes apps file was corrupted, and I restored what I could. But now a lot of the apps are missing from iTunes.
They're on my iPhone 4S, and various other Apple devices, but every time I sync my iPhone, the sync deletes the apps from my phone that it can't find in iTunes. I've re-downloaded them onto my phone, but I can't find a way to re-download them to iTunes. So the next time I sync to add music to my iPhone that I've purchased elsewhere and imported into iTunes, all those apps get deleted again. More hours spent downloading apps back to my iPhone and placing their icons where they belong. Very frustrating. And one old app that is no longer available from iTunes, but one that I use daily, is now only on my old iPod Touch - so I can no longer sync it, without totally losing that app..
This problem first started when I tried to update to iOS 8.3 from 8.2. The update failed for some "unknown reason", and I had to restore my iPhone to the backup made just before that update. The restore dumped all my apps and all my music. When I tried to re-sync my music, it only restored about 1/3 of the songs. So I've had to re-sync again, and again, trying to get all the music back on the iPhone. And every time, it dumps most of my apps.
My questions are: Is there any way to get the old, highly valued app from my iPod Touch back into iTunes on my Windows 7 PC? And is there any way to get the missing apps back in to the iTunes file on my PC from my iPhone?

Follow the instructions here or here.
