Audio problems with MOV to FLV

I have a .mov (Quicktime) file I wish to convert to a SWF
using Flashing CS3.
The resulting SWF file plays the video portion fine, but the
audio portion cuts out about half way through. no sound at all till
the end of the movie. The original mov file plays fine.
Any idea why this would occur?
When I convert the file I am choosing "Progressive download
from a web server", using the default settings in the Encoding
screen, and selecting a skin.
Thank you.

google for 'bitrate calculators', some are 'online apps', no download, nor purchase..
they can give you a hint, if 100kBit/sec or 6.5Mbit/sec is your dimensions..
bitrate bascily calculates codec, res, framerate, 'speed' of content
example: a fullTV res video (NTSC/PAL), encoded in h264 (which is allowed within a flv) has an excellent quality with a bitrate of ~800-1000kBit/sec ..
compression is not only techniqué, but more an art ..
e.g. a talking-head needs less bitrate than a 'skater movie' ...-
use 30sec of your project, create 5 diff versions with diff bitrates ...
it's only you who can decide: good AND small enough..

Audio Problems with some HD channels (HBO mostly)

I'm experiencing sporadic audio problems with a handful of HD channels. Most noticably on HBO.
When the audio is output through the television itself, it sounds OK... however if the audio is output through my home theater receiver and speakers, I can hear a lot of static and "crackling" on certain movies and shows.
The issue isn't the home theater setup, as I have several other components that use it (AppleTV, Bluray, Xbox, etc.) and the audio sounds perfect from them.
The only device that displays that poor audio is the FiOS Set Top Box and even then it's only on a few channels.
I thought maybe that the optical audio cable between the set top box and the receiver may have been bad, so I replaced that. Same problem even with the new cable.
The problem is either with the Set Top Box itself or the audio levels on the stream from the channel provider.
Has anyone experienced anything similar to this, and if so... did you resolve it somehow?
Any help you could provide would be most appreciated.
Thanks!

Check the following.
Help & Settings > Settings > Entitlement Information
Here are possible entitlements mapped to channels.
101 - 104 : PSB HD
407 - 433 : Essential Extra / Unlimited Extra
446 - 453 : HD Extra
501 : Sky Sports 1
502 : Sky Sports 2
507 - 509 : BT Sport SD
510 - 512 : BT Sport HD
513 - 514 : Essential Extra / Unlimited Extra
530 - 540 : Sky Movies
555 - 563 : Kids Extra
You need 'HD Extra' for channels 446 - 453. I have the free 'BT Sport HD' but that does not cover entertainment HD channels. You need to subscribe to the HD Extra bolt-on for £3 for them. Have you ordered HD Extra (it only became available from last Sunday)?

Problem with movies imported from iPad3

Whenever I import footage into imovie, the footage looks good. When I put that footage into a project it stutters.
It doesnt matter if I specify 24fps or 30fps, the movie judders and stutters.
I do not have this problem with movie footage imported from any other device.
Any ideas?

Firewire audio problems with OS X 10.5.6

Hello,
I’m experiencing audio problems with Firewire 400 on my Macbook running Mac OSX 10.5.6.
I’ve got a 2.4Ghz IntelCore 2 Duo with 4 GB RAM and 59 GB available on the internal HD.
It’s hooked up to a brand new Mackie D.4 mixer with 2 Firewire outputs. The problems occur on both Firewire outputs.
I’ve installed automatically from the software update (which I will never do again) to 10.5.6. I never tried the D.4 with 10.5.5 so I can’t tell if the problems occur there also.
The main problem is that after a couple of minutes of recording the sound starts to break up and get really distorted. After a while the sound comes back again.
The second problem is that Soundtrack Pro or Audacity don’t get any audio input from the D.4, although audio input is clearly visible in System Preferences – Sound.
The only sound program that works with all 14 Firewire channels is Ableton, but also in Ableton the distortion occurs.
An example of the distortion can be checked here:
http://media.kaalslag.com/firewire-distortion-problem-mackieD4+Macbook.mp3
I’ve roamed several forums and sites to solve the problem and I tried these solutions:
I updated again to 10.5.6. with the full combo download from the Apple site. Restarted. Problem still there.
I shut Airport off, because lots of sites mentioned problems with Airport conflicting with audio/firewire. Didn’t work.
I did the work around with shutting the Macbook off, disconnecting the D.4, restarting the Macbook, opening Audio/Midi Setup, connecting the D.4 again, toggling the format frequencies a couple of times. Again, no use.
Right now I’m using my “old” Macbook again to record from vinyl. This one is still running on OSX 10.4.11. No problems so far.
I’ve had the distortion problems occuring before with an USB interface. Hoped that the Mackie Firewire would solve the problem, but it seems now that there’s a serious audio Firewire problem which is still not solved in OSX 10.5.
Any help, tips and/or a work around would be much appreciated. Thanks!

You could try using another computer in Target Disk mode (as an "external HD"), or you can connect the firewire cable and disconnect all other network cables (turning off airport). Then on each computer go to the "Network" system preferences and select "Built-in Firewire" from the list of ports and choose "Manually" from the drop-down menu next to "Configure". Enter the following IP addresses and subnet masks, apply the changes.
_Computer 1_
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
_Computer 2_
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
After those ip addresses are entered and you've clicked "Apply", ensure that for both computers you have file sharing enabled (done in the "Sharing" system preferences), and then check the Finder sidebar to see if the computers can see each other (their names should appear under "Shared" in the sidebar--if not, try restarting).
If the computers dont appear (even after restarting), using the "Connect To" option that's available in the Finder's "Go" menu. In there, to connect to another computer enter it's IP address as follows:
afp://IP_ADDRESS
If you're on the computer with the ip address of 192.168.1.1, you would enter 192.168.1.2 as "IP_ADDRESS". The "afp" is the protocol (just like "http" for web), and stands for "Apple Filing Protocol"...Apple's file sharing protocol.

USB audio problems with 2013 iMac

I'm having a strange audio problem with USB microphones and headsets. The issue with my Logitech H650e is shown in this screencast I recorded. In the first part of the screencast, I am not speaking into the mic—yet you can see the levels fluctuating as if there is static playing (not in a natural pattern that you'd see when someone is speaking). In the next part of the video I demonstrate that selecting the built-in iMac mic for input, and then re-selecting the Logitech headset temporarily solves the problem. You can see the input start to fluctuate normally as it should when I am speaking. But at 0:31 in the screencast, you can see the input levels freeze and stop registering anything. I continued to speak until the end of the screencast, but no input was detected. For this screencast, I was on a Go To Webinar call, but the problem occurs regardless of whether I'm using Skype, Go To Webinar, GarageBand or any other software.
The problem with my Blue Yeti USB microphone is also different. In that case, the input does not freeze as it does with the Logitech headset. The levels appear as you would expect, and it seems to work. However, the person on the other end can hear static in the background, even though I don't hear it in my own headphones. I learned this because I just tried to do a Skype interview with the Blue Yeti, and the interviewer told me they could hear static. We closed Skype and called each other back twice, but the problem persisted. Then, suspecting the problem was related to what I described above with the Logitech, I unplugged the Yeti and then plugged it into my Macbook Air 2013 (also running Mavericks). Lo and behold the static completely disappeared.
My Griffin iMic and Audio Technica lavalier mic (attached to the iMic) behaves similarly to the Yeti, except in this case I can hear the static when I speak with my monitoring headphones. The input works but I get a lot of cracking and static in the background. This was confirmed by calling the Skype Test Call number and recording a message, which is then played back.
Here are the facts:
All 3 of my USB audio microphones/headsets do not work with my 2013 iMac running Mavericks
All 3 of these microphones/headsets worked fine with my 2008 Mac Pro running Mountain Lion
All 3 of these microphones/headsets work fine with my 2013 Macbook Air running Mavericks
In this other thread, several people are reporting similar issues with the iMac 2013 and Mavericks. At least two people did not have the issue when the iMac 2013 was running Mountain Lion. This of course suggests the issue is the combination of the iMac 2013 and Mavericks.

Audio problems with Droid/X

When sending voice messages using Cloudtalk, the recipient hears only garbage. I contacted Cloudtalk technical support, and it appears that the 3gp file sent by the phone is not recognized. This problem is known by them, and happens only on Droid/X.
Anyone else is experiencing audio problems with the droid/x?

That doesn't sound like an audio issue with the X, it sounds like a compatibility issue between the X and the service.

Audio problems with CHS 435

Hello all, I'm having audio problems with my FiOS set top box. When I start to change channels I lose audio and can't get it back unless I turn the TV off/on or I change the HDMI source on my TV . Seems after changing a couple of channels the problem happens. I've tried the in home agent auto correct, and different HDMI cables. I have a Westinghouse TV and I'll try a firmware update for the TV and see if that fixes it. Any fix for this and the possibility that it might be the set top box ? I just got FiOS and all is going well besides this issue. Seems that the other STB that are model # 335 aren't having this problem.

Some TVs have had issues with the HDMI handshake and the Audio. You may be required to use the separate bulkier HD Component cables with separate audio cables. Or try it as a solution on that TV.
I have CHS 435 DVR on a Samsung, and 2 CHS 335s on different model Vizio TVs, all with HDMI, and no issues. Others have reported different issues. I did a search here with the following results. Perhaps this information will help.

Audio problem with one episode of iTunes tv show on two apple tvs but audio works fine on same show on iMac

I have a season pass to Dr Who and all 30+ other shows purchased on iTunes work great. Last night's episode (Hide) has a hissing sound so loud it drowns out all the audio in the show when i try to watch it on my Apple TV. I then downloaded the episode to my iMac and my iPad and no audio issues there. However when I tried playing it shared from my iMac to the Apple TV and the audio problem was there again. Same thing happened when I tried to AirPlay from my iPad to Apple TV.
I have two Apple TVs. One is latest model w latest upgrade, the other is generation before without latest upgrade. Same audio issue on both. I have tons of iTunes TV shows and movies and this is the only episode with an issue. Something is wrong with this file that causes it to screws up the audio on Apple TV.
Has anyone else seen this kind of audio issue specific to just one TV episode or movie? Anyone know support path for iTunes problems?

If other episodes play Dolby Digital fine this could be a file encoding problem - they sometimes get it wrong.
I suggest you all contact Apple about the problem via itunes store support here:

Keynote Problem with Movies

I wonder if anybody can help with a weird problem. I made a two-slide presentation I'm keynote that included a music track from iTunes. I exported to QuickTime and it worked perfectly. I uploaded the movie (.mov file) to Dropbox and the audio dropped right at the point where the second slide would have started. I then uploaded the the movie to Vimeo and the audio dropped in the same way. So to recap, the audio in the movie fully played out when I opened it in QuickTime on my Mac but dropped halfway through when I ploaded to Dropbox and Vimeo. Does anybody know why this is happening and how to fix it?
Much appreciated.

Probably because the iTunes file has an embedded Digital Rights Management certificate which prevents unauthorised publishing of copyright music to web sites such as Youtube.

Audio Problems with Fast/Slow/Reverse Effect in iMovie HD

I have been having problems with the Fast/Slow/Reverse effect in iMovie HD with my movie clips. Whenever I apply the effect (reversing at the same playback speed, not sped up or slowed down), when it is finished rendering the audio is choppy, yet on time (but still backwards, as wanted). Before applying the effect, the preview of it works flawlessly, it is only when it is applied that the audio gets choppy. Extracting the audio will not help either because the video will still be playing backwards while the audio will be playing normally (since it can't be reversed on its own). I have tried other effects on the same clips that don't effect the audio and they work perfectly. Any suggestions? I'd really appreciate your help! Thanks.
Macintosh Powerbook G4 Mac OS X (10.4.6) iLife '05 : iMovie HD

Have you got an isolated hard drive with ALL of the required applications and other resources together with the operating system ? Using an external HD to SAVE a running iMovie project is asking for problems. Back up the Project on another HD sure, but don't use System on one HD, running files on another.
Hope Helps,

(Audio) problems with MPEG2 content

Hi everybody,
I have the following problems:
I have 2 movies, MPEG 2 format. I bought the Apple MPEG-2 component for Quick Time, the movies play fine. Then I trimmed them using Quick Time X and saved them as a "film", i.e. not changing any contents (at least this is what the menu information says).
1st problem: The movies still play fine, but strangely have the same file size as the source. How is this possible, if I have trimmed them (I actually cut both of them in half)? Info says the codec of the trimmed movies is "m2s", while the codec of the source files is "MPEG Layer 2, MPEG-2 Video".
Then I assembled a DVD using iDVD 7.0.4. When previewing the project in iDVD, everything seemed fine. I then saved the project as an image file.
2nd problem: When previewing the image file with DVD player, there is no audio. The image quality is fine, but no sound at all.
3rd problem: The iDVD .dvdproj file I created the image from is suddenly bigger than 5 GB, which is roughly the size of the image I created. Also, I can't open the project file anymore without causing iDVD to hang at startup.
Does anybody have a clue what is going on? Any help is highly appreciated!
Thank you!!

No, every codec is compressed. But it is a question of how much, and in what manner. Some codecs compress each frame in the same way image files are compressed (intraframe compression). Some codecs also use incomplete information for the frames, relying on prior frames for some information (interframe compression). Codecs with interframe compression save space, but are not good for editing because your software has to recreate a complete frame when you are creating an edit point, which takes extra time. So different codecs have been devised to fill different needs and applications.
Mpeg2 is done in such a way that it is space efficient and high quality, but introduces enough artifacts that once you transcode to mpeg2, you are better off going back to your source if you ever need to edit again.
There is uncompressed video, but I would call that a format rather than codec (compressor/decompressor). If you converted your footage to uncompressed, it would take up somewhere around 100GB for each hour. DV only uses 12GB per hour.

Audio Problems with Quicktime and Flash

Hi,
For some reason, my Mac has stopped playing audio from flash and movies. I have no idea how this has happened as I cannot remember changing any preferences. This has occured with movies that I've watched before that I know the audio works on.
Does anyone know what I can check?
Thanks,
Steve.

It is a known problem and Apple even has a KB article about it.
It seems that some apps might change the sound prefs and in doing so, they keep some other apps from playing back sound. Opening a GB loop will change the settings back to the default, but you can also do it manually following the directions in the KB article.
Why they just don't change it so that those apps do not change the sounds prefs without notifying you of the possible effects, I have no idea.

Audio problems with import

I am using a jvc gz-mg 155u camera and have made 2 previous movies with no audio problems.
I have about 1 hour of video in many different clips that i am trying to import.
1) Not all of the clips "thumbnail" when the import window opens. when i click on any clip in the import window, the audio plays.
2) When i play the video on the camcorder, the audio plays
3) When i import the video clips, some of the initial clips have audio associated with them, but the latter clips do not.
In summary, it has worked fine before. Only some of the clips work now when imported and audio works fine in playback on the vid cam.
I just returned from costa rica and i am very anxious to build my trip movie.
any suggestions??

Thanks for the fast reply. Much appreciated - I have found other reference to this since reading your reply, and I can see this should fix my problem.

Strange audio problem with my MacBook Pro

Hello everyone,
first of all I should say that this is not the well known "no-audio-from-internal-speakers-and-red-light-burning-on-microphone-jack" audio issue on many MacBook Pros. However, I still hope some of you experts can help me.
Here's what happens. At some point of the last few days, I realized I was not getting any sound from my Mac's internal speakers except the typical boot sound on startup. Then I opened the System Preferences/Sound window and saw that I have only one output option: "Headphones - Headphone port". No internal speakers at all. This doesn't mean I can use my headphones at all... When I connect them to the computer with my System Preferences still open, then the option "Headphones" change automatically to "Digital out" and no sound comes out of them. If I take them out, then I can see the red light for about half a second, then it's off. Ironically, I still can hear some sound (even perfect audio) out of my headphones when I don't put them completely into the jack but at some very unstable point at about 90% of the connector's size.
I can use the function keys F10-F12 to mute or turn up and down the sound... Everything seems to work - still no sound comes out. I thought of course of a hardware problem but I can hear the mac startup din-dong effect like always and I even let the AHT run with no negative results. I also tried repairing the hard disk permissions, as I read somewhere, with the Disk Utility. Still no results.
Anyone to give me a clue what's happening on my Mac? I bought it about 2 months ago, and the software is up-to-date (Mac OS X 10.6.6).
Any help would be much appreciated. Thanks,
Luis

Hi friends
I too have a macbook pro running 10.6.6 and an odd audio problem which has recently shown itself and although different to Luiscv's problem, may well be related.
My audio works fine through the built in speakers but gets all fruity with some but not all audio as soon as I plug in the headphones. I get crystal clear audio when playing mp3's through quicktime whether I have the headphones plugged in or not.
youtube flash movies through Safari and VLC .mkv files are problematic. I do get audio but the stereo sound somehow gets split so the dialogue gets very quiet and fuzzy and the musical soundtrack gets louder.
If this is a codec/decompression issue why does the sound come good when I unplug the headphones? Why are some files totally fine with both headphones and internal speakers?
I have updated perian, zapped p-ram, repaired permissions all to no avail.
Thanks in advance to anyone able to solve this one.
Best wishes,
Wayne Batistic
