i have a MacBookPro5,5 how do i connect it to my hdtv WITH BOTH AUDIO AND VIDEO? and where can i buy this cable(s)?

thank you roger. i have attempted to connect my mbp now 3 times (all different ways with different cables purchased) but unfortunately no success. i understand that with me having an older mbp it can be a challenge. i have found this page http://www.wikihow.com/Connect-a-Macbook-to-a-TV but with my unsuccessful history, i have become skeptical. i will try your suggestion and let you know. thank you again.

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting
Hope It Works

Extra hardware interface for transmiting both Audio and video to client ??

hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
but my code is working fine for either one at a time.
DO i need some extra hardware interface for Transmitting both Audio and video to client im using code AVTransmit and AVReceive found from this site only
After running TX
i give dsound:// & vfw://0 in Media Locater only sound is received and no vedio
and when i give vfw://0 in Media Locater only live video is transmited.
im using JMF1.1.2e.
if any one know the method to run or cause of it plz reply me soon. i will be very thankfull
transmiter/server side code .first run TX on server

I'm also getting some really bad sound quality on facebook notifications. I've been forced to disable them they sound horrible like they are clipping.
Trying to figure out if this is a problem on all Late 2013 15" macbook pros or if mine is defective? This occurs even at around 20-30% volume levels with the Facebook notification sound problems...

How do I use my web cam to record audio and video? I can get the video to work but no sound.

I want to record both audio and video at the same time. The video works fine but not the audio. I do use Skype without any problems using both.

PwmBoat,
This made me smile, because things like this do make me smile... I never make videos on YouCam, but I did this time, so I could test this one out.
You did not say what webcam software you are using...
======================================================================
Video and audio recording works on YouCam V3.5.1.4606
Make sure you have turned on a working microphone in Settings:
YouCam > Right-Side Settings >
Right-Side, Lower-Right, Select a working Microphone from the Drop down list
AND
CHECK "Capture with audio"
OK
You can also buy (for $38 US) YouCam 5.0 from the Cyberlink.com website and it has audio/video and all sorts of other goodies, too. (They have 3.x as well, but why buy what HP already gives you?)
==========================================================================
I hope this helps!
We work hard to help!

AV digital works audio only on touch but both audio and video on ipad

The av digital accessory does audio only on the Itouch but works fine on the IPad showing both audio and video?

To try and keep it simple, there are 3 variables here.
1) Acquisition - You can either record with a stereo or mono mic, you've probably used mono.
2a) Capturing - In the 'clip settings' tab of the log and capture window, you can choose how you want to capture your audio, choosing from the 'Audio Format' drop down menu.
2b) Editing - If you've already captured some material, in the timeline, check the audio tracks. If, for example, a clip has audio tracks a1 and a2, and you can see 2 sets of small triangles at the start and end of the clip, you have stereo audio.
(double click the audio track and in the viewer you will see a 'stereo a1a2' tab with linked stereo - any changes you apply here will equally apply to both tracks - although you can 'pan' the audio using the 'pan slider' for example, if you want the sound of a car approaching to start in the left speaker, then move to the right speaker as it moves past on screen)
If there aren't the triangles, double click the audio and in the viewer you'll have 2 seperate mono tracks - mono a1 and mono a2 - assuming you haven't captured the audio format as 'mono mix', ch1(L) or ch2(R).
You can link seperate mono tracks in the timeline by selecting the audio clip and hitting opt (alt) L, (similarly, you can unlink stereo track by the same procedure).
If you've got a single mono track, you can duplicate the track and then link, pan, etc as required - can't remember exactly as it's ages since I captured single channels.
3) Output - The decisions you make in 2) determine how your content willl be outputted. (Is 'outputted' a word?)
I'm by no means an audio expert so I hope this is clearer than mud.

I am trying to export a video from Premiere Pro. I have both audio and video checked and the sequence is active but only the audio exports. There is no video at all. Can anyone tell me how to get the video to export. It was working fine until today.

Premiere Pro CC has been working fine until today. I have completed my sequence and it is active. I have both audio and video checked when I am exporting using H.264 with Match Source Hi bitrate. I am choosing entire sequence. The audio exports but the video and title does not. Can anyone tell me how to troubleshoot this so I can complete this project? Please!

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

Mini DisplayPort to support both audio and video coming soon?

So I notice that Apple updated the MacBook Pro Mini DisplayPort implementation to support BOTH audio AND video.
Think this will make it’s way to the Mac mini soon, or an update still a long way off?

Probably in the next refresh, but the mini was refreshed twice last year, so another refresh in less than a year would probably be too much for which to hope!
There is always this US$49 wonder;

MacPro update Mini DisplayPort both audio and video?

Apple confirmed to Ars that the just-updated MacBook Pros will pass both video and audio signals to an HDTV or receiver when using an miniDP to HDMI adapter.
Just wondering if this is true or if anyone has tried it out yet?

Hello Rick! Thanks again for the reply. I took the one adapter back but at the time they had no other new ones to replace it with so I just took the refund. I was back in town at my brothers so i checked them out again and they had 3 brand new never opened adapters. I bought it again. It actually worked.
My bro had the audio splitter cables so I connected them and it did work. So not sure if the adapter I bought has the audio capability or not because I used the other audio out on the MBP. The one where it is headphone to RCA..whatever those connections are called.
I will try the adapter on a Toshiba 26" TV I have at home with just the adapter and see if audio comes through or not. I hope it will.

Trouble getting both audio and video out of 2009 MBP.

I had this working fine a few months ago, and then upgraded to a Pioneer elite stereo, now either audio or video work, but not simultaneously, even if I connect video to TV directly and audio to stereo directly, I can't get both to work it's either or. I've set the stereo to accept the optical input, and as I said above, it doesn't even work if I connect the audio to the stereo only while the video goes to the TV. Really seems to be a software issue, any ideas?

the receiver will need to be set so the tv is one of the optical inputs. so that is why you are only hearing one or the other. the tv expects to get sound from a different source other then your opical input.
on my jvc there is a setting where I tell the receiver. The tv sound is digital so it'll find the digital signal and associate it to the tv sound.
What is your exact model receiver I'm sure there is a PDF of the instructions online.

How can I get cross fade/dissolve of both audio and video?

I want to centre the coss fade/dissolve transition on the clip boundary. I can do this with the video cross dissolve but not the audio cross fade - for the audio, the Alignment facility in the Edit transition is greyed out and the transition can only be located to the left or right of the clip boundary. It seems an obvious requirement and surprising that audio cross fade is not, optionally at least, an integral part of the video cross dissolve (as it is in Corel VideoStudio).

Steve - thanks for the reply.
Yes I am working in Timeline mode and have done what you suggest - i.e., drag in the video transition followed by the audio transition. However, despite my original update to the question, I now cannot centre the audio transition on the clip boundary - it worked once as reported but not since.
Basically when I drag the audio cross fade transition on to the timeline, it will only let me drop it to the left or right of the clip boundary. I then hightlight the transition and click on the edit transition button. The properties are displayed and I can alter the length of the transition but the wording in the alignment row of the properties is greyed out with the setting being "End at cut". The down arrow head to give the drop down with the other settings is grey and inactive.
I don't understand how I made it work once!
Any ideas?

That will be due to the network
If on wifi try Ethernet
Make le sure there is no other activity occuring (ie other streaming, network backups etc)
To see a current status of the network get a report from istumbler or similar. Look for signal strength, noise, nearby networks

Airplay both audio and video through different devices

When is it gonna be possible to airplay audio on my Bose Airplay Speaker and the video on my TV? Is it about the update of the iOS?

This is a user forum so no one can answer that. I wouldn't count on it though.

Synched Audio and Video Capture in JMF?

I am in the planning stages of developing a speaker's corner for our university television station. Essentially, a button pressed by the user and a JSamp will send serial data to the computer(PC) that will execute the capture program. Before I proceed further, will I be able to capture both audio and video so that they will be in synch so that I can later bring both into a commercial video editing platform? Also, does the JMF support capture by firwire or USB only? Most of the forums seem to indicate that it is USB. Thanks, and any other advice would be appreciated.
