.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

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!

I lose sound after about 20 seconds on video in CS6. It plays fine outside of CS6. Why?

I lose sound after about 20 seconds on video in CS6. It plays fine outside of CS6. Why?

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

How to make my movie clip move slowly towards right after a few seconds?

Hi,
I have the following code which will bring my Banner_mc onto the middle of my Introduction page with some effects. Now, I want this movie clip to wait for a while and then move to right until it disappear with the same effects. How can I do that?
var BannerFadeTween:Tween=new Tween(Banner_mc, "alpha", Strong.easeOut, 0 , 1, 6, true);
var BannerRotateTween:Tween=new Tween(Banner_mc, "rotation", Strong.easeOut, 360 , 0, 6, true);
var BannerXTween:Tween=new Tween(Banner_mc, "x", Strong.easeOut, -300 , 500, 6, true);
var BannerYTween:Tween=new Tween(Banner_mc, "y", Strong.easeOut, -125 , 300, 6, true);
Thanks in advance for any help in this regard.

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

Airplay losses connection after a few seconds

When using my Iphone 4s connecting to apple tvm I lose connection after a few seconds.

Welcome to the Apple Community.
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

I somehow set my toolbar to disappear after a few seconds, making the screen jump, very annoying, how do I set it back so it stays visible all of the time?

I can't remember where I found the option to make the toolbar invisible until I moved my cursor to where the toolbar usually shows. If I move the cursor again, after a few seconds the toolbar disappears causing the screen to jump up and fill in the space where it was. It is so irritating and I can't find out how to make it visible all of the time.

You can try to check the '''Options''' for the different '''Extensions''' in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons'''. Starting Firefox temporarily in [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode] may also help determine if an installed add-on is causing the change.

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

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

While running how do I get my podcast to play one song and move to the next and not skip to the next after a few seconds into the song?

I recently started running and downloaded the Couch to 5K webcasts, while running how do I get my podcast to play one song in it's entirety and move to the next and not skip to the next after a few seconds into the song? I beleive it's the motion of the running that is causing it, is there a setting I need to change?

Hello nowrunning,
Is the "Shake to Shuffle" option turned on in your iPod's settings? To check, head to Settings -> Music -> Shake to Shuffle and make sure it is set to Off.

[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.

MacBook Pro suddenly loses power, returns after a few seconds

Hello,
I have an issue with my MacBook Pro, in that it sometimes (once or twice a day) completely appears to lose power. The screen goes black, and also the keyboard illumination goes out. It looks like a complete loss of power. However, after a few seconds, the machine can be awoken again, and nothing has been lost. The only thing I have noticed when this happens is that the wifi connection seems to sometimes - but not always - drop.
Could anyone help me is to what could be the problem? My previous MacBook had a problem with the screen connection, but given the keyboard lights going out it has the impression of a power or sleep issue.
Thanks in advance.

Does Firefox switch to full screen if you press F11 ?
You can also try the F10 key to see if that brings up the menu bar.

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.
