Sound Frequency Spectrum Limited When Exported

I've been trying to export the sound from my Final Cut Pro project for my friend to master in a sound program on his computer. He requested my sound in the wav format, so I used QuickTime Conversion to do so. When he looked at the spectrum, he saw that the sound frequencies were cut off above 16,000 hz. We've tried to export in other formats, such as AIFF and AU, but with the same results. Is the sound being limited during conversion or could Final Cut Pro somwhow be doing it before the conversion? Some of the sound tracks I'm exporting have been previously mastered and definitely did have sound above 16,000 hz. Most importantly, how can I export the tracks with their full frequency range intact?

I am having the exact problem, it's a real show stopper.
I have tested hardware, software, media as below.
Tested on
1 Intel 17inch iMac
2 G4 AGP 450 + 1.2Ghz Model
Each have a fresh install of iLife 06 on
Each have been tested with different project files.
Differnet music files
The issue seems to be with apples iLife software to me.
I am on the phone to apple right now, they only surgest I create a new user as it generates new prefs, but the above test has already rulled out preference files!
Also rebuilding and reinstalling, but again the above test has rulled that out as the 3 machines were freshly built.
I have already upgraded my graphics card in my machine at home to sort out preview problems with iMovie, hopefully it's not going to be an expensive audio card aswell.
If any 1 can throw any light on this please do as apple support can't.
Regards
Paul

How do I get a descent sound level and quality when exporting out of Logic ??

Hi guys,
I know this topic's been discussed many times before but I still can't fix my problem
I'm going crazy right now. It's been weeks I've been working on beats on Logic and I think they now sound pretty cool.
So I'm trying to export them out of Logic on mp3,or wav, or aiff but everytime it comes out very low. So when I'm applying different tips (limiter, adaptative limiter and different things I found on the internet... ) the sound level is a bit higher but still the quality is not as good as it is on Logic
So here's my questions : first, is it possible to get the exact same quality as the one you have when listening into logic ?
then how to get the best quality with a normal sound level so when you listening to the mp3 or wave or aiff on itunes just after a normal song you don't have to turn the sound up
Thank you very much for you help !!

Imovie - sound in advance only when exported ! impossible to change-

Hi,
Finishing my movie for my vacations, and it is pretty annoying because when I export the video, the sound (from each video) doesn't match anymore with the image… It would be simple
During the preview everything is good and then it becomes wrong…
I don't know what to do !
I've exported it several times, deleting the sequence with problems, putting it back, trying to kill the sound… I'm tired !
Thank you so much for your help !

Hi again,
This link below solved it, just about a bug on imovie 9 if you put slow motion or accelerate on different points than the ones suggested (100%, 200%, 400% etc), if you are not on it it bugs…
Better answer there

Sorry for double conversation…

I am having trouble keeping the quality of my video when exporting to my external drive. I change the kind to "original" but when I view the video from the external drive once exported, the sound and picture are distorted.

I am having trouble keeping the quality of my video when exporting to my external hard drive. I have tried to export from iphoto with changing kind to "original" but when I open the video from the external drive the quality is effected. I have also tried copying the video to my desktop and then dragging and dropping onto the drive...same problem. Any suggestions? I would like to save everything to my external drive so that I can delete all of iphoto library and then reimport to correct a few things.

The file sizes are identical. In the finder I did a search for all .mov files. Then when they came up, I went through them and named each one so that they would be easier to find. I am a new mac user and am used to windows. I realized later that I should not have done this....with a mac files should be named within iphoto app...not finder....When I went to open the videos in iphoto, it wouldn't allow me. I had to go into finder, copy to desktop and reimport into iphoto. Then the videos worked again. However, I had the problem with the poor video quality when copied to external drive before that. Actually the first problem I had was when I copied to ext drive...videos were copying as an image...so I learned that you have to change "kind" to original before exporting....then that problem was solved...now they are videos, not images but not of a great quality. Skips, sound and images are not in sync...etc...

How can I email a video clip I downloaded into my iPhoto library to my friends? I tried creating an email and attaching the clip but there is no sound and no picture when the 5 minute attachment "plays." How can I file= export it to them from iPhoto?

Have them install Quicktime on their PC's from Apple's website, that's the easiest fix.

Limits on data length when exporting to text?

Are ther and limits on the with of a report when exporting a report to a text file. I'm in the process of creating a file for upload into the banking system. The file is exported as a text file and contains 1464 characters in width. I am able to display all the fields in my report preview, but when I export the file to .txt it seems to cut it off at character 206.
Any suggestions
Thanks

Hi Kevin,
Check to see if you can export to csv and get the length you need. I'm thinking about writng a program to convert csv to fixed length ascii records.
Ooops, looks like it might be 256 for csv. But... if a program was written to look at the csv field count to specify the fields in an ascii record then you could use csv to a mulitline detail report and the record could be built that way. I'm thinking of writing it for myself, but why not share.

[PE9] noise or no sound when exporting

I'm putting together a video from a trip. After a while, my computer started getting slow and Premiere Elements almost instantly showed a memory error when opening my project. So I arranged a faster computer to borrow for a while, which solved the memory problem.
Now I want to share/produce/export my project as a movie, so I can watch it and write down things I want to change. Rendering as an avi results in an "unknown error", other formats seem to work fine apart from the sound. I either get a continuous noise or no sound at all. I literally tested every output possibility in PE9.
I assume it's not the project itself, because I did preliminary exports before which looked and sounded fine. The difference is: those exports where made on my own computer, the one that got to slow in the end. So it's not the footage used, everything sounds just fine in PE itself.
The new computer is brand new, with barely anything installed except for PE9, Windows, VLC and Chrome. Is it possible the computer lacks the proper audio encoder(s)? I thought those would be installed with PE9...
So in short:
- old computer exports movies perfectly fine, but when I open my project PE9 exits immediately, due to not enough memory. I simply can't open my project anymore.
- new computer can handle the load, but produces noise or silence instead of the sound.
I exported two very short clips, one in MPG and one in MP4, the export settings are in the filenames. Both clips are the same content-wise and you should hear a bit of Johnny Cash as the soundtrack. But you won't.
http://dl.dropbox.com/u/4832845/HD%20720p%2030.mpg
http://dl.dropbox.com/u/4832845/iPod%20and%20iPhone%20-%20High%20Quality.mp4

Sorry, it's been a while since I had the time to dive into PE9 again. I updated the audio drivers and installed Service Pack 1 for Windows 7. That seemed to solve the problem briefly, because when I exported a short bit of the project, I had the correct sound. When I tried it again a while later, it was the old noise again. Very weird...
I continued my project in a new project (because the first one seems to be too much for PE9 to handle) and when I export bits of the new project, everything is fine. So it's probably a file used in the first project that causes the mayhem. Maybe one of the mp3's I'm using, although they're all self ripped from my own cd collection.
Still weird that it renders ALL of the sound useless when exporting. Also, PE9 doesn't indicate file problems (as I've seen in the past, with the little yellow danger triangle in the bottom left corner). I guess I'll have to split the project up in several smaller projects and see if I can isolate the troublemaker that way.
I didn't have the time yet to figure out the video codec used, but all footage is from the same camera and the mp3's used are self ripped. The computer has now been updated to the max.
I did however start the first project in PE8 and continued with PE9 later, when I moved to a new computer. But that shouldn't cause my audio to be messed up, should it? Using any of the standard presets results in noise or silence. I've tried them all
Also, when I export the new project (which was started in PE9), it exports to avi just fine. When I try avi in the first project (started in PE8, continued in PE9), I get the "unknown" error and exporting to avi or wmv is not possible.

My recordings sound so different when exported to iTunes. What am I doing wrong?

Google's been useless in finding answers.
I made a couple songs. They sound perfect on Garageband. After exporting, the songs sound awfully mixed on iTunes. I mean, awful. I've tried messing with iTunes EQ, Garageband visual EQ, Garageband compression (not that I fully understand compression), the auto compression when exporting, and good ol fashioned volume control. Nothing changes for the better but it always sounds correct on Garageband and god awful otherwise.
I have a chord that plugs in from my mac to my instruments so I use good mix of both real instruments and software instruments if that makes any difference.
On a side note, the recordings only sound good on my personal headphones. Heaven forbid I use a car stereo or any sort of speakers.
If anything, what can I do to remedy this problem?
Many thanks for any help you can give.

There is a fix coming out soon for this. In the mean time go to settings and put the date forward one year. then try. once you have access then put the date back.
hope it helps

Common No Sound when exporting to all video formats.

I am trying to import a video into FlashPro8. I had a wmv(with sound) file and bought QPro in an attempt to convert to flv. No luck, won't even allow me to open the file....Nice, Then told to get flip4mac. Done! File now opens but no luck... all exports have no sound. Then I ask the client for MPG file instead of troublesome WMV format. Still no sound. Now I have no option to encode the sound at all in any format with this mpg file when exporting. I export to MOV ...no sound. Is there a simple answer to this issue without jargon that i won't understand?

MPEG won't export with sound from QT at all. You can, however, export MPEG 1 and 2 from MPEG Streamclip, to all QT formats.
Flip4Mac in the non-free version(s) will allow opening of WMV then export to QT from WMV format. The free one won't.
Toast 7 will take a lot of formats and export to MPEG 1 via the make VCD menu or MPEG-2 via the make Video DVD menu. You make the VCD or DVD then mount a disk image and rip the files - in the case of VCD the AVSEQ##.DAT file is a MPEG-1 and you can just rename it.

Rogue Sound when exporting to iDVD - HELP!!!!!!

I wonder if anyone can help. i have spent 100's of hours putting together a 50 minute movie that combines lots of clips from the same source together with stills. I have used multiple transitions and I am using the photograph theme.
I have two problems. Firstly although the movie plays perfect sound throughout in imovie when I export it ti IDVD the movie sound deteriorates for the middle part of the movie only. Despite having set the sound to zero on the clip - as I am using background music the sound still plays. i can't get rid of it. i have tried deleting and re-adding the clips from the source event, detached the audio, you name it and yet I cannot get rid of the sound. Secondly and again only in this middle section I have rogue sound appearing at a particular point in the film from a clip which is earlier in the movie - almost as if the sound has become detached and moved. I have checked and checked but can't fix it. I even exported the soundtrack only to Imovie to see if that would work but it did not. I AM OPEN TO ANY IDEAS - HELP

Is it realistic to think Apple will fix the bug soon?
We're not supposed to speculate here - no-one but Apple would know anyway! Hopefully, the next version upgrade (? iMovie '10) might address it.
One option for you would be to use the free program JES Deinterlacer to do your speed changes. My understanding is that it does a better job of slow and fast motion than iMovie. You would need to import your clips into JES, process them, export from JES, then re-import to iMovie - all a bit messy! But you would get the desired result.
If you leave the clips in iMovie with their current speed settings, you will almost certainly experience the audio glitches on export. So, you either need to change the speed to the presets, or use a 3rd party product such as JES Deinterlacer to set the speed for you. Bear in mind I haven't tested this (with JES) but believe it should work.
The product can be downloaded from this site:
http://www.xs4all.nl/~jeschot/home.html
A link to an 18 MB video (by David Lute) showing a comparison of JES Deinterlacer slow-motion vs. iMovie slow-motion can be found about one third the way down the page. Unfortunately, there is no mention of the iMovie version used for the test.

Sound drop out when exporting to Quicktime movie.

One track of three sound tracks drops out after a few seconds then reappears a few seconds later when exporting to QT Movie. The project functions perfectly when printing to video. Am using QT 7.1.3 FCE HD 3

Hi(Bonjour)!
Try to make an "audio-mixdown" of your final sequence
in timeline.
Michel Boissonneault
Thanks for the info. I managed to overcome the problem initially by copying onto miniDV then re-capturing and exporting the result., but Mix Down is much nicer.
However, prior to upgrading to FCE-HD, I am fairly certain I have made more complex projects with no problems. Now quite frequently I get a message suggesting I reduce the number of RT tracks, or increase the speed of my computer. Is there something in FCE HD that requires these modifications, or have I a rogue project.
Does anyone know what is the actual difference between High Medium & Low qualities with Audio & Video?
Thanks

No sound when exporting .mov

Can someone please look at these HBO videos and tell me why none of them will export with audio?
http://www.hbo.com/deadwood/video/index.shtml
All the HBO online videos are like this, they have no audio when exported.

You can't "save" streaming media.
Therefore you can't "export" the file.

Frequent interruptions when exporting to camcorder

When I export an edited movie back to the camcorder (Sony DCR TRV 240E; DV IN/OUT) I get small interruptions (freezing or vertical shaking) in the picture frequently (once every 60 seconds (approx.)). These interruptions are not there in the editing mode they occur on the iMovie screen when exporting and gets on the tape. I have tried with another tape with the same result.
Later on tape the interruptions also influences the sound.
Has anyone encountered this?
I would be very grateful for help.

iMac G4 Mac OS X (10.3.9) I use iMovie 4.0.1.

a) in your system prefs, there's a tool "File
vault".. that has to be OFF, editing video
b) is your project on internal drive, or on an
external..? is the ext. hd usb(2) connected? should
be firewire...
c) your internal drive should be "crowded" ~80% of
max. single-click on hd's icon, hit apple-i, have a
look....
Hi Karsten,
Vault is off and the project is on the internal drive. The internal drive was crowded; 93% used. But even after moving 30% and get 63% free space on the internal drive the symptom is still there.
The frequence is every 60 seconds. The magnitude of the interruption is varying.
Should I do something more after emptying the trash after copying/moving?

Distortion in audio when exporting HDV to tape

I'm having trouble sending a native HDV project back to tape. The picture looks fine on the export, but the audio is severely distorted. It's not overmodulation. I have a -10 limiter on the audio master track, and the VUs on my deck don't show anything like any clipping. But the sound it's making is similar to clipping. Any ideas? Thanks,
Stu

Howard,
Thanks for the reply. It's hard to describe the sound...it actually reminds me of the sound a 16mm projector makes when it loses its loop, sort of a strobing distortion. As for constancy, no it's definitely not constant in the sense that, say, ground loop hum is constant. It's "attached" to the sounds as the play back, so that when the timeline is very quiet it's hardly audible, but when you get any sound at all, it comes up. I know that might sound like clipping, but I don't see how it could possibly be for a few reasons:
1. There's a -9 limiter on the audio master track.
2. It sounds perfectly fine both in timeline playback and when exported to Encore.
3. The VUs in the original source clips, the timeline, and the deck on output all show clean levels with no clipping.
I'm wondering if it's related to my deck, but I haven't had a chance to check that yet. I'll try outputting to the camera when I get back in to work on Monday, but if you have any other ideas as to what the cause might be, I'd be happy to hear them. Thanks.

Poor sound quality in timeline and export; fine in Source?

Hello all.
Newbie to Pr but experienced pro in digital audio. I'm stumped and know I'm just missing something somewhere.
I've made a music video for one of my songs. The graphics are all done (in AE), imported to Pr and eveything looks great. I import the final mix of the audio and it sounds very low quality when played from the timeline and in the final output, regardless of format (I've tried several presets and custom settings as well). I played around and noticed that the audio sounds fine when played from the Source window inside Premier.
The Pr session is comrised of 18 video tracks (not all playing at once, of course) and one stereo audio track.
I've tried re-exporting the audio from Logic at different bit depths, sample rates and file formats (mp3, wav, AAC, etc) but the results are the same every time: Source (Pr)sounds fine, Logic output sounds fine, rendered / timeline playback sounds like very low quality mp3 and final product sounds just as bad.
I've tried everything I can think of. I hope one of you can show me what I'm missing.
TIA!

Thank you for the reply!
I was experiencing the same results no matter what export settings I used. Plus the poor sound quality was present in the timeline itself, without even exporting the project.
I finally threw my hands up, started a completely new project, drug the same audio file in... sounded fine. Copied / Pasted the video clips from the original, broken project and boom, eveything is fixed. Yeah, corrupted Pr file it turns out. All I had to do was start a new project and import all the old components.
I've had to do this in Logic a lot (increasingly, these days). I just wish I'd tried it 10 hours earlier! Ha.
Anyway, problem solved, and thanks very much!
