Exporting .avi to .mov using h264 loses sound after a few seconds

Here's a weird one. I am editing some movie clips, and when I do an export to .mov format using h264 compression, the audio drops out after a 8-10 seconds.
At first I thought it was happening after an edit jump, but nope -- it just cuts out for some reason. I also cannot export to MP4 format without losing the audio completely (shows as MPEG Layer 3 audio in the properties window of the original). When I look at the Properties for the exported movie, I can see the audio length is not the full length of the video.
I have edited clips like this before in QuickTime with no issues, not sure what is going on. I tested on MPEG Streamclip and I can export to either format with no sound issues.

Hello George,
Sorry I can't help you with your problem. But it is TOO much of a coincidence that YOU do everyday (try to, lately!) what I am trying for the first time-- converting .avi files to .mov files. I just got a cheap movie cam and it saves files to avi format. I am able to transfer them successfully to my Mac, but cannot find a third party avi converter. If you can help please email me: [email protected]
thank you for your time and I hope SOMEONE out there will help YOU!

.mov import - loses sound after a few seconds

Hi, this is my first time posting in a forum and using a video editor so I'm a REAL newbie! I have several .mov files that I took from my video camera that I am trying to import. When I add the first moving to the timeline the video looks great. However, the audio drops out after a few seconds. In the audio screen I can see squiggly lines show audio for the first few seconds and then just a flat line of no audio. I can't figure out what the problem is. Please help!
Thanks!

Report back with the codec details of your file, use the programs below

Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project

And what does "CS6" refer to exactly? In any case, ask in the product forum of whatever program you are referring to and for the life of it provide more info like system specs, file types used and so on.... "This doesn't work" posts are useless.

Brand New Macbook loses connection after a few seconds causing my other products using wifi (android & iPad) to lose connection too. Very Frustrating

- Mac book is 3 days old
- The Mac book would connect for about 10 seconds with the WiFi then it would disconnect
- A prompt which states that another device is using the IP address which is in conflict with his Mac book
- Both the iPad and Android Phone lose internet connection when the Mac book attempts to access the WiFi signal of the DSL-2642B
Am really confused on why it hasnt been connecting, will connect to internet on my android phone and girlfirends iphones WiFi hotspots when i activate them but as i said the Macbook may connect to my router for a few seconds once i have unplugged and replugged my router but drops out and causes my other devices to drop out. The other Devices (Ipad and Android Phone) will connect and stay connected to my router only until i try to connect the macbook, prompting all devices to drop out.
Any help here would be GREATLY appreciated

Find a location with a faster Internet connection. The slow connection message is telling you you have a slow connection or one that's too busy.

.MOV's Audio Cutting out after first few seconds????

If anyone could assist me I would be extremely grateful. When I import .mov files into Premier Pro cs5, it cuts out after a couple of second. Any other file works fine, it’s just the mov’s. If I play the QuickTime outside Premier it works fine. Does anyone have a solution?
I am trying to compile a video of a range of different clips from my trip in India.
The clips details:
* Various dimensions but average: 640x480
* 30 fps
* Photo – jpeg
Is there something specifically I should select when setting up the file?
Thank you to whoever has to patience and knowledge to help me out.

Have you installed the Premiere Pro CS5 (5.0.2) update?
What operating system are you using?

I use zap2it and today after a few second it goes to yahoo with this in the searchbar:yui yahooapis skins assets carousel build.

It works on Safari.

It could be the work of one of your add-ons, or even add / mal-ware.
Look thru your add-ons list and make sure you know what each one is
and what it does. Also, check the programs that are on your computer
'''Windows:''' Start > Control Panel > Uninstall Programs.
'''Mac:''' Open the "Applications" folder.
'''Linux:''' Check your user manual.
Go thru the list. If you find something that you don't
know what it is, use a web search.

Losing sound after a few minutes

When using iChat for audio chats (or when using Skype), I lose sound after a few minutes. The person I'm talking too starts hearing the same thing in a repeating loop, and we have no cut off. At that point, it sometimes works to start a now voice chat, but sometimes it doesn't.
This seems to have started when I replaced an ailing snow ABS with a D-Link DSL-G604T wireless router. I've read a lot of posts here that talk about the need to turn on port forwarding, but that doesn't seem to be the problem - I can start talking, sometimes for as much as a half hour, but at some point the connection goes bad. (I thought it was just my iMac, so I tried my iBook with the same results. Then I thought it was my headset, so I tried my iSight - same thing happened.)
I'm convinced it has something to do with the router, but can't figure out exactly what's going on. Any ideas?
Thanks!
Mac OS X (10.4.6)

Hi Kirk,
Does the Buddy List close up and say it is Disconnected ?
Is the connection 1.6meg in both directions ?
What have you got System Preferences > Quicktime > Streaming speed set to ?
Also how are you opening the ports in the D-Link ?
These pics suggest it has UPnP

Sound from videos stops after a few seconds on Quicktime

I bought a new Samsung camera and took some videos at a concert. When I put the videos on my MacBook Pro and try to play them on Quicktime, the sound stops after a few seconds. When I try to play them on iMovie or use them in iMovie, not only is there no sound after a few seconds but the sound that is there is sped up.
The audio works fine in VLC but doesn't seem to work with anything else on my Mac. I've tried Perian, Flip4Mac...
Codecs: H.264, AAC
Help?

I've seen this issue in the past. I think it is connected to the operating system itself. I say this because I reinstalled the os using itunes and then restored a backup. Then garageband started behaving again. Then the issue came back - after I did an os update. So I'd try reverting back to a fresh version of the latest os, and then restoring your apps using a backup.
Hope it helps

You can also try the F10 key to see if that brings up the menu bar.

My mac pro wont start. I push the power button and I get a click sound. A few seconds later another click sound and that it.

My mac pro wont start. I push the power button and I get a click sound. A few seconds later another click sound and that it. I've tried different power plugs. Going direct into the wall, through a power strip. By iteslf, with other devices plugged in. I removed hard drives, and some RAM, and nothing. Sometimes it would not turn on, and then some minutes later it works. So its was sparatic, but now its been the same situation for three days where it wont turn on.
I'm guessing power supply, but I wanted to see if anyone had a similar expereince and what the solution was, before I drag this beast to my local Apple store and have them look at it. Its a real pain to get it there and back and I want to be armed with some info for them. I already dragged this to them when it first started to do this, and of course it started up just fine for them. And you know if it works for the Genius then theres nothing wrong with. No matter what you explain to them.
I figure if anyone had a the same problem and was able to resolve it, I can relate that experience to the Genius even if it start up for them.
Thanks

Try a SMC Reset using the extended method:
Remove the AC power cord.
Press the power-on button. [This drains the stored charge from the power supply]
wait a quarter minute.
Restore the power cord, being certain to JAM it into the socket, as the big block of rubber inhibits proper seating.
wait a quarter minute
attempt to power on.
If no joy, examine the button battery half-hidden behind the graphics card. Remove it to measure the Voltage. A new battery should not cost over US$5, and measures a little over 3 Volts. BR-2032 is used in garage door opener controls and car door locks controls. The geeks at Radio Shack can measure it for you.

[MBA 2013]sound crashes and restart after a few seconds

Hi guys,
I bought a Macbook Air in June 2013 and 2-3 months ago, I started having problems with the sound.
Basically, there is always one of those things running : iTunes, VLC or youtube/soundcloud so I always use the sound.
After some time, the sound is strange like it is dying. After a few seconds, it stops working and then I have to wait around 5-10 seconds for it to be automatically restarted. I don't have headphone or anything plugged in and no external sound card.
All my drivers are up to date and I have the last Mac OS X version (10.9.4 I think).
Does anybody know what I should do ? Format it ? Uninstall all the software like Boom, Accubeatmix (maybe they cause the problem but I've used them since I have the MBA).
I am used to using linux commands in a terminal if there is some dirty things to fix that so feel free to share those.
Thanks.

I uninstalled Boom and it seems to work now. Strange that it worked without any problem for a long time.
I'll install it again and see what happens.
Thanks.

on my ipad 2 video streaming stops after a few seconds, only sound is playing .what could be the reason and how to solve this problem.
I have a feeling that it may have started after upgrading to ios6.

Hi,
Is this failing with Error 20 ?
Sometimes in a the router or modem if you use Port Forwarding then you are your Buddy may be missing the Screen Sharing Port.
The Screen Sharing part uses a different port to the Audio port.
As the port for Audio (And therefore Video) are known and can be port Forwarded it is the random Screen Sharing port that can be the problem.
iChat 3 info http://support.apple.com/kb/HT1507 that includes Bonjour and Jabber info
iChat 4 info http://support.apple.com/kb/HT2282
If you are not using (or your Buddy) UPnP then I would change the method of opening the port to that.

My MacBook will not play videos. No sound and the video stops after a few seconds.

My Mac book pro will not play videos. No sound and the video stops after a few seconds.

Hello GrahamBIOM,
I understand while viewing a video or listening to some different content, you lose audio, is that correct? I will do all I can to assist you with this issue.
Does the issue occur when you have headphones inserted? If you are not sure, if you have a set of headphones available could you test that please?
Please respond back at your earliest convenience with results.
Thanks
