Audio disappears from video once encoded

I have a DV NTSC sequence that I want to encode as an flv file. The original video is from MiniDV. When I export the sequence as a quicktime movie, the sound plays fine. When I re-encode it as a .flv file, there is no audio.
Below are all the things I've tried to fix the problem, which have not worked...
I tried using Sorenson Squeeze, MPEG Streamclip & DVKitchen to encode the file.
I tried exporting the audio track as an AIFF, then re-imported it (replacing the audio track with the AIFF).
I output the sequence to MiniDV, digitized, exported and encoded.
Re-digitized footage from the master into a new project
I am using Final Cut version 5.0.1
PS- I have been encoding similar videos successfully for 6 months now. This is the only time I've had this problem.

Since this tends to happen to me when sequences get (mildly) corrupt, have you tried using another sequence? Not necessarily duplicating, but creating a new sequence then copy-paste the contents from the old one? 9 times of out 10, that clears this hurdle.
Or was that one of the steps you tried?

IDVD 6 - Audio Disappears from video at 49:55 time!?

I hope you can help me out!
I've been working on a DVD that is just over 55 minutes in length.
The single video file is a DV-NTSC QuickTime Movie with chapter markers, as exported from Final Cut Pro 6. I know FCP inside and out, as well as QT, but the iDVD situation is puzzling.
So, all audio plays fine in the FCP timeline, QuickTime movie with chapter markers, and iDVD menu editing area.
The audio abruptly quits at the 49:55 minute mark when a DVD is compressed and burned with iDVD 6. The same happens when I make a Disc Image and play the image with DVD Player-- the audio stops at exactly the same time.
All other iDVD projects work fine!
What are your thoughts on this?
Thanks,
Andrew

Interesting. What is happening at 49:55 in your video? At 55 minutes, you're pretty close to a full disk at max quality -- are your preferences set for Best Quality (1hr+ productions) or Best Performance (<60 min, but depends some on how many menus, menu music, DVD-ROM, etc.). You might try best quality to see if that makes a difference.

How to Delete several Audio clips from Video clips on Timeline of APPro CS5

I would like to know how to delete multiple audio clips from Video clips at once in time line in APPro CS5? Please advice step-by-step procedure. I can DELETE audio from a single Video clip. But I wanted to DEL Audio from multiple video clips. Your help is much appreciated. Thanks

Thanks for the advice given by Shooternz, Colin and Jim. Your help is much appreciated for a beginner like me... Jim's idea was also good..It worked for me and also safe if I need to use the original audio. Following method also found good...but previous audio clip cannot be extracted after deleting it. ... 1. Hold down "ALT" key first then select the first audio clip in the chain of video clips to Delete. 2. Hold down " Shift + Alt " keys together and click right mouse button on all audio clips to be deleted one by one. Make sure only audio clips are selected. 3. Then release ALT+Shift keys and then click right mouse button and select "Clear" from pull down menu to Delete all selected audio clips on the time line. This method works very well for me. Thanks for every one who has adviced me how to do it. Thanks guys... If u all find better method tha above...please inform us. Thx.

For the second time in one week, my dowloaded film stopped and disappeared from Video. apple apologized and will refund me.have some,others the same problem?

My dowloaded films stopped after a while and disappeared from Video. How come can this happen?

I cant explain it but this bizarre "fix" works many times if your videos "disappear". I have passed this on to a number of people and it has worked for them. You can try it if you like.
Go to your home screen and swipe to the right to bring up the spotlight search feature. Type in the name of the movie that you were watching. If the movie appears in the search, tap on it to begin playing. If it plays, let it go for a few minutes and then hit the done button to stop it. Then go back to the Videos App and see if the movies and TV shows have reappeared.

Issue with Random Blocks of Audio disappearing from Timeline

I am having a problem with seemingly random blocks of audio tracks disappearing from my edit. I will be scrolling through somewhere I haven't worked on or even looked at, in a few hours or days, and I'll be missing chunks of audio. At first I thought I was just losing my mind, but I can see that transitions that I've tacked on at the ends to fade in/out are still there in their "storylines", just floating by themselves. Its almost like they were just straight up deleted by hand. But I know that I didn't do any such thing. So, what is going on? This isn't the first time its happened, and its impossible to know when it does, so I could end up losing hours of work reverting to a backup. But it is equally frustrating (slowly) flicking back and forth between two projects to copy the audio tracks back every few days. It also mostly seems to happen on audio with transitions/crossfades, but I have found a few places where it has just been reduced to 1 frame. Weird.
I am working on a fairly complex film about 45 minutes in length, with compound clips of synced interviews cut up in the "Main" storyline, then with action shots and info stacked on top, and some 1-3 minute music tracks and video-less narrations below. Working on a 5 month old MBP, 10.9.5, 16gb ram, everything's up to date
I just need this to stop happening is the main thing. What can I do about it? It is very frustrating that these bugs are still popping up all the time. Not a thing that should be expected from a "pro" application.
Thanks for any insight.
Screen Shot below is example: you can see where 4blocks have been deleted, just leaving the crossfades hanging. Extremely annoying, and time wasting.

This is a user forum. I have not seen the issue you describe before.
You could use the Provide Feedback command in the application to give feedback to Apple.

Songs disappear from playlist once in a while but are still in library

Every now and again I notice that a song has disappeared from a playlist. I can copy it back to the playlist from the music library. But what makes the song drop from the playlist? It's either a song I purchased from iTunes or one I imported from cd. Doesn't matter.

Not a Sony Vaio. I have one of the first iPods. It was a gift. It's not that songs disappear from the playlist in the iPod, but from playlists on the computer. They are in the music library and I have to copy and paste them back into the playlist I want them in. I haven't lost any from the music library, fortunately.
The playlists (I have a bunch of them) are blue with a music note. The songs in the playlists have checkmarks next to them, and are all checked. They just drop out of a playlist every now and again and I have to copy it back in. I can go for a while and think "hey, I haven't heard X in a long time". And sure enough it's dropped from the playlist in the computer, and I have to copy it back in from the library, then resynch the iPod. Really weird and mildly annoying.

Airport Express won't join network and disappears from view once configured

Hi. I am having trouble getting my brand new Airport Express to connect to my network. I would appreciate any help you can provide. Here are the details:
Computer: iMac, G5 running OS X Tiger.
Network: Cable modem hooked to a netgear wireless b/g router. The router is configured to use WEP 128 bit encryption. I have connectivity on the router throughout the house on several computers and handheld devices (iPhone, etc).
Airport Express Version: 5.3.1
My goal is to add the AE to my current network in order to stream music from iTunes to my receiver.
When I initially opened up the airtunes utility to set up the AE the setup program was able to find the AE and walk through the configuration process. I followed the steps, entered the correct network name, encryption algorithm, password, etc. When I completed setup and hit the update AE button the AE disappeared from the setup application and the device began to flash yellow. While troubleshooting I have reset the AE dozens of times over the past couple of days. I have done both the reset with power on (press reset for 10 seconds waiting for the quickflash) and the hard reset (plugging the AE in with the reset button depressed until the quickflash starts). In either case, the AE is rarely detected by the setup utility (about 1 in 10 times). When it is detected, I walk through the set up and get the same results. I have attempted configuration using both the manual configuration option and the automatic "wizard-like" method.
I have tried to configure the AE wirelessly with it plugged in next to the computer and using a direct hookup via ethernet cable. Both methods produce the same results - flashing yellow light with AE undetectable by any Airport applications.
I have also tried to load an older version of the firmware (5.3) on the AE. When I hit the update AE button after configuring the update to go from the current version to version 5.3 I get an error message stating that "an error occured while attempting to update."
Thanks in advance for any help you can provide.

Hi guys,
I think I'm having the same problem as you all, and its driving me crazzzzy!. I added an AX to my existing network with a AEX all thru gigabyte switch, including the new AX. I set the brand new AX up with all the settings, hit update, all settings were configured and its working fine (i can see it in iTunes, stream music to it, all works fine) EXCEPT when i go to AU and try to go into the manual setting of the AX it just hangs, and after about 2 min, i get an error message:
"An error occurred while reading the configuration. Please make sure your Apple wireless device is plugged in and in range of your computer or connected via Ethernet and try again. (-6722)"
I have tried resetting it hard/soft/default but not sure if it really does reset it, still keeps same password, and network settings. Tried connecting it next to my existing AEX incase the AX is trying to communicate via WIFI instead of the hard wired ethernet. I'll try hard wiring it directly to my mac as some have had success.
I have tried using OX 10.5.3, but still misbehaves as b4 with OSX.4.11. So its not my mac setup.
I'll try to find the old firmwares as some have described, that might work....????
This seems a common problem to many, I hope that Steve & the Apple engineers have got these messages and are fixing the problem as we speak.

HT1657 Rented movies won't disappear from Videos on ISO 7.0.4

I recently downloaded an iTunes rental to my iPhone. Previously after watching it, a swipe was all it took to delete the rental and image from Videos. Now it's not that easy. It stays under Videos with a little white cloud icon in the corner. It's not taking up space on my iPhone but I'd like to delete it. Upon synching to iTunes, no rental tabs or info is shown on the device. There is no way to delete it. I asked a Genius and he thinks it stays on the phone like music that's now downloaded, almost like a history of rented/purchased stuff. It's annoying how Apple chooses to constantly make things tough that worked simply at one point. Any help would be appreciated. Thanks.

If it has the cloud symbol then that indicates that it's in the cloud and not on your phone, but is available for redownloading - if you go into Settings > iTunes & App Store and turn Videos 'off' (under the 'Show All' heading) it should stop it showing in the Videos app. What you can redownload will still show in the Purchased tab in the iTunes store app.

Still photos disappear from video

I am just learning Premiere Elements for a newspaper where I work and designed a 4-minute video in which I dropped into the Timeline in 2 different place a series of four still photos. When I re-opened the file this morning, all the photos were missing from the timeline (the rest of the video was fine). In adding the photos through the 'Get Media' tab should the program not have added them for good or are the photos as they show in the Premiere Elements Project pointing to files on my desktop? In that case, perhaps I moved the original photo file folder? Does that original folder need to remain in one place for the life of the project? I may have uploaded the stills from a file in my paper's Staging area that is purged the following day.
Thanks for any insights. I have since re-imported the photos adn re-done the timeline which was a hassle.
Douglas

Douglas,
I found that the FLV played fine on my cable-modem connection (via my wireless g to my laptop). Now, for faster Export, you might weigh the lower connection speeds vs the resulting quality. Personally, I err on the side of quality, until the Webmaster starts complaining that too many users are still on dial-up, but that's just me.
Now, I was listening on the laptop on the patio (not the most critical listening environment, or method), but found nothing objectionable. The overall Audio levels might be a bit low, but at least should not blow speakers, if users have the volume set to max - unlike some music videos. The lack of an external mic connection is a big drawback, even on some higher-end video cameras.
I also found the result quite good. My wife has the G-10, but has never used it as a video capture device - impressive in your use.
The subject and location were interesting, as well. It's been far too long since I hiked the New River and surrounding areas.
Thanks for sharing,
Hunt
PS - did you solve the disappearing stills issue?

Why is audio disappearing from Extracted Sound Track File?

I extracted the +Sound Track+ from a .mov file which was originally a .wmv file I'd edited and saved in QT Pro. Regarding the original movie from which I extracted the Sound Track, +Movie Properties+ indicated the +Video track+ as being +Sorenson H.263.+ The Sound Track extracted was +MPEG Layer 3.+
+MovieProperties/Audio Settings+ displayed Sound Track as a Mono audio track.
The extracted sound track appeared in a new QT Window/Player as "Untitled".
I hit play and the audio track played. I saved it as a Self-Contained Movie, hit play and it played again, no problem.
( +Movie Properties+ still displayed the +Sound Track+ Format as MPEG Layer 3/Mono)
I quit QT Pro and turned my attention to other projects in other applications.
Later, when I booted QT Pro and tried to listen to the Extracted Sound Track File, I hit play and the playhead moved, but there was no audible audio, or indication of audio in the equalizer display. It was as if the audio had disappeared. Opening +Movie Properties,+ the +Extracted Sound Track+ still appeared as MPEG layer 3/Mono and the track was still enabled.
On a hunch, I opened and played the original Movie from which I'd extracted the sound track. After that, I hit play again on the Extracted Sound Track Window/Player and voila! -- the audio miraculously reappeared and was fully audible. I don't understand. Why is this happening? I did save the Extracted Sound Track file as a self-contained movie. It doesn't make sense.
More to the point, _how does one extract a sound track and save/process it such that the extracted sound track remains intact with full playback capability, without first having to play the original movie from which it was extracted in order to make the Extracted Sound Track file playback._

Thanks RT...
The curious thing is, if I boot the computer and open the +Extracted Sound Track+ file in Quicktime, it's hit or miss. Sometimes the audio is there. Sometimes it's not. If I however, play ANY other Quicktime Movie on my computer and THEN open the +Extracted Sound Track+ File, the audio miraculously reappears. What can it be?
I've got Streamclip. Haven't used it much but I'll try your approach and export the file back to a Quicktime Format.

Audio disappears from clips after moving them around in between track Premiere

I was working with multiple video clips and movement them around not paying attention to how it was overlapping the audio sometimes. When I finally finished my audio from alot of the clips I cropped have disappeared.
How do I get/link them back?
Videos are Estill there just no sound

I'm guessing you accidentally overlayed some of them while you were working.
A quick way to fix this is to put your playhead (CTI) over a clip you want to add the sound back to, select it, and then press 'f' to match frame back to the original. This will load the original clip with the in and out marks set in your source window and you can drag it down to overlay the clip with the missing audio. This will replace the original clip and audio.

Audio extraction from video?

I have a few songs from concerts, am I able to take just the audio from the video and convert it into an mp3 file?
Thanks!

please add som infos about your set-up in 'My Profile', it makes it easier to give the right answers...
iMHD allows in its Quicktime/Expert Settings the selection of .aiff, which is the audio-only of your project.
in a second step, you can add that aiff file into iTunes, which converts it in mp3, if you did choose that in iT's prefs ...

Is there anyway to seperate audio podcasts from video podcasts?

is there any way to view a listing on video podcasts tthen a listing of audio podcasts in itunes?

Does anyone know of a solution ?
The only solution to remove this data from your phone is to go nuclear: Restore your phone as a "new" device in itunes, followed by syncing your content back to your phone. ALL data on your phone will be erased, including these "phantom" email addresses. There is no other way to remove this data from your phone.

Premiere CS6: Mutlicam audio "unlocked" from video

Hi all, I'm new to Premiere CS6 after working with Liquid for years, so apologies if this is a stupid question. I tried to scan the forums for an answer but didn't find anything, so here goes:
I am syncing three separate video files using Multicam with the same Marker point. (No timecode) The resulting Multicam file syncs up perfectly, video AND audio, in the left-hand window. But when I select new Mark In and Mark Out points on the file to add footage to the Timeline, the audio track no longer syncs up. It's almost like I've changed the video Mark In spot, but not the audio one... Which makes no sense, since the Multicam file should be its own separate entity?
The flipside: When I add that piece of footage to the Timeline, the audio (in the Timeline) is re-synced once more. So my end result has video and audio perfectly in sync... but when I'm auditioning footage in the upper left-hand window, the audio doesn't line up.
Like I said, I'm sure there's some simple solution I'm missing here. Thanks in advance for your help.
Rich

Hmmm. Well, I imported each video clip into the Media Bin, then screened them one-by-one in the Source Monitor. At the appropriate mark-in spot, I set a Mark In on each clip.
Next, I highlight all three clips simultaneously in the Media Bin, then right-click to choose "Create Multi-Cam Sequence." And I select "Marker Point." Premiere then creates a new clip in the Media Bin, renamed "Clip1MutliCam" (for example). I click on THAT clip and all 3 angles appear in the Source Window.
My problem arises when I start adding Mark In & Mark Out to the Multicam Clip so I can add footage to the Timeline. The audio goes out of sync in the Source Monitor... But the same footage, when placed on the Timeline, has synced audio once again. So the issue is in the Source Window only.
Sorry for not explaining that one better. I haven't tried syncing clips in a sequence. Again, I'm just a novice at this... My method seemed very similar to how Liquid does MultiCam, so I assumed it would work in similar fashion.
