2 Way Video Clarity with 1 Way Audio Distortion

I consistently experience the following issue:
During a 2 way ichat using isights, we both experience clear video, the other individual has clear audio from me, but I can only received distorted, unintelligible audio. I have tested this with multiple Mac users and the 'appleu3test01'.
-Connection Doctor displays 100% for video and audio.
-I have set up my fire wall ports according to settings found in this forum. (I've turned the fire wall off to test as well...)
-I have re-configured my Internet wiring multiple ways, including a direct wire from modem to machine. Currently I run Cable/Modem/AirPortExtreme/VonageRouter
-Yes, I have search and read through these forums and other support areas on the web for trouble shooting tips.
Alas, I am at a loss. I have found serveral posts concerning this same topic, but to my knowledge no one has yet to find a solution. And I was hoping the latest software updates would do the job. Nope. Until I tested with appleu3test01 I was beginning to think it was a problem on the other end because they could receive my audio and video. Now I believe something is blocking their audio on my end. But what?
You help is appreciated. Please assume:
1) I have run through the various 'checklists', FAQ's, and topics that I could find in this forum. But I admit, I'm only willing to try so many searches.
2) I am an experience/knowledgable comp/network/internet user. Feel free to try and stump me.
Sincerly,
David

I'm so happy. I don't know anything about Bob and uncles, Ralph, (although, ironically, I do have two uncle Bobs) but you're a Rockstar in my book - as we say over here.
Problem: Audio clipping distortion as a result of too much internal gain.
Solution: Use Internal Audio Output as my iChat audio output Setting
I have been using an M-Audio Firewire Solo (MFS) as my primary Audio Device. The setup was like this:
computer source/m-audio/speakers
I have the latest driver for MFS (http://www.m-audio.com/index.php?do=support.drivers), but they have yet to release a driver for 10.4.3
The MFS device always links internally with my master (computer) volume settings. So whether I attempt to change the audio output through the M-Audio Firewire Driver Application or the Audio MIDI Setup (Application/Utilities/Audio MIDI Setup) the output volume is always linked - meaning you change one you change them all. I do have two external 'gain' control knobs on my MFS and Speakers, but changing those settings does not aleviate the audio clipping distortion. The result is always audio clipping within iChat.
I can leave both audio systems connected and simply change my output audio settings to Internal Audio or Firewire Solo.
Last Side Note: I believe many other issues were solved along the way, but this was the final issue interfering with iChat. Other things that helped:
1) For a wireless network, placing my Vonage VOIP router post the AirPort Base Station.
2) Updating to 10.4.3 and the most recent Airport update (including updates for my computer and firmware for the Airport Extreme).
3) Updating my iSight to 1.0.3 and making sure I have a good firewire cable connecting my iSight to my computer.
Hope this helps. It feels great to have the mystery finally solved.

Can quicktime play an video track with multiple alternate audio tracks?

Hi,
If I have a video track with multiple alternate audio tracks (say different languages), can a user select the audio track of his choice and play in Quick time?
Thanks,
Apurva

Does quick time/ safari have this capability?
QT (i.e., the QT structure embeded in current Mac OS/device IOS versions) has the ability to switch between alternative audio tracks assuming the file is properly encoded and the compression format is supported. QT 7, QT X, iTunes, and similar app player GUIs can switch between such tracks during playback but the QT plug-in cannot. In a similar manner, devices like TV can switch between such tracks but an iPhone cannot just as an iPhone can select "Chapters" but the QT browser plug-in cannot but an iPhone file programmed with both chapters and alternate audio tracks can be played back through a TV device and access both chapters and alternative audio tracks.
What I want to use is one video track with alternate audio tracks in a set level manifest and play this using HTTP Live streaming. I'm using the manifest mentioned here :
http://tools.ietf.org/html/draft-pantos-http-live-streaming-07#section-8.7
Since I do not use playlists, I am not familiar with the approach in your example. If I want alternate audio and/or video tracks, I create standalone video files with these features built in. Nor do I use RTSP if that is what you mean by "live streaming" of content. If I want to "stream" the content, I use "Fast Start" files programmed to open in the QT player app which supports these features or create reference or QT Media Link files that do the same thing.
As you mentioned, Safari on my iPhone is playing the default/first alternate audio track mentioned but not giving an option to switch tracks.
Neither Safari nor the Video app GUIs on your iPhone have a built in switching option. The only way to switch to alternate audio tracks is to do so with QT 7 Pro or possibly iTunes before loading or streaming the video file. (Am still speaking about a standalone file here and not a programmed playlist/RTSP switch.)
However Quick time on my Mac machine only plays the audio with the the video stream and not the alternate audio track.
The QT player app GUI only switches between tracks that are stored as part of the standalone file. Basically, QT files may contain up to 99 individual data tracks. In alternative audio videos, multiple audio tracks are added to the file by an editor like QT 7 Pro but only one track is designated as "active." All other tracks are designated as "inactive." The QT player GUI allows the viewer to select which audio track he or she wants to hear and then turns off the current audio track and turns on the selected audio track. Otherwise all active tracks would play simultaneously.
Is there a way to switch tracks on my iPhone on Safari?
As previously noted, the default track can be manually changed by QT 7 Pro or, I believe, iTunes (used to have this capability) before actually loading or streaming content.
Does quicktime have this capability?
As far as I know, only with regard to stand alone files programmed with multiple alternate tracks. I am not a HTML, HTML5, or Java programmer so I assume there may be web alternatives here but they would be beyond the scope of my expertise.
Do you know any free player that can do this?
Again, I don't use either playlists or RTSP so I've never had a need to look for/use alternative players that might meet your needs. I simply find it easier to build files that work correctly in current player app/device GUIs already having these capabilities.
Or the very last option, can I build a player to do this? If yes can you suggest where/how I start?
Once again, I assume this might be possible but not part of my experience since, for my part, easier work flows are available.

Still images interspersed in video all with the original audio

I have what I think should be a very simple task. I have a 1 hour video of a school show. I want the soundtrack to remain intact. I simply want to take still images and replace the video images for certain chunks of the school show. The result should be a smooth original audio with the original video interrupted for 4-5 second periods with other images. For a bonus, it would be nice if the stills cross faded to the original video (without affecting the audio).
I have been trying to get the precision editor to let me do this and cannot get it to happen cleanly and reliably. I keep getting the audio duplicated or dropped audio. And if I try to add cross fades it is even worse. The help video on the precision editor does not make it clear to me how to do this.
In some PC programs, I know you can split the video independently of the audio and then delete the video clip and replace it with a still image. It does not look like iMovie is that intuitive.
If there is another way to do this, I would love to know about it.
Please help.
Thanks

In iMovie Preferences, make sure you have turned on Advanced Tools.
Drag the photo to the video frame where you want it and drop it. When a pop-up menu comes up, choose Cutaway.

Multiple video tracks with the same audio track

How do I get DVDSP to play the same audio track on 3 different video tracks without having to repeat the audio on each of the 3 video trax?
Seems simple, but I can't find an easy way to do it.
Anybody got any ideas?

Yes they are all one continuous stream with the same GOP structure and everything. I had to export them as QT movies from FCP to get them all the same. I only exported the video though becuase the audio was going to be the same for all the tracks, & it was already done as AC3 through Compressor. Which brings up an interesting question; why does DVDSP convert the AC3 audio to .aiff which is a much larger format?
I'm trying to go back and look at the encoding log from DVDSP to see what error it gave.
It doesn't give the error in the log since I had shut down my computer last night, so I guess I'll have to try the build again and see what error it gives.
I'm looking at the parsing files and .m2v files that DVDSP did during the build, and it parsed all 3 angles, and finished the .m2v file of the medium shot, including 6 minutes past the point I told DVDSP to stop it. (When exporting the QT movie from FCP, I had forgotton and encoded the whole 2:30:00 show instead of the 1st 1/2 of 1:16:47:15, and then just adjusted the end of the clip in DVDSP).
The wide shot and Close up .m2v files, and the audio .aiff file were in the folder, but have nothing in them. The Video_TS folder and Audio_TS folder are also there, but with nothing in them, so whatever happened, seems to have happened in the medium shot encoding process.
I'm pretty much over this multi-angle thing, and I'm going to start working on an edited version of this today because all I have to do is make the cuts between cameras, since the audio is already mixed. However, if you have any other ideas, please let me know.

Working with video clips with 5.1 audio

Someone has sent me a video file which has 5.1 audio. I'm going bonkers trying to figure out how to mute individual channels in this file. My final project will be stereo and I may not want the audio from the rear channels in my final mix. I can't figure out what search terms will lead me to the answer in the Premiere help file. Can anyone help me with this one?
J. D.

You should be able to right click your source file and select Modify->Audio Channels
And then enable or disable channels you'd like to use:
Please note that this can only be done BEFORE use of clip.
Hope that helps!

Rip video with secondary/dual audio stream from dvd to ipod

I see that my 160gb ipod has an option in the video section for secondary audio. I assume this means a video file or .mp4 can be created with 2 different audio tracks. I want to be able to have a video file with the standard audio and commentary track. I have searched online and I have seen a couple of sites that claim their software can do that but the demos Ive tried havent worked. Does anyone have any experience in this? Or does anyone know of the definitive program to use?

i just downloaded this program, but when i pop in a dvd, it won't open up. do i have to be registered in order for this to work properly?

How does exactly AMS sync a video stream with another stream of audio only ?

I have the following situation: 2 instances of FMLE on one machine and another machine with AMS Starter.
The instances of the FMLE are:
1. Video H.264 + audio MP3
2. Audio only MP3 - track 1
The application on AMS is a livepkgr/_definst_ and i am using HDS with a live event
I have an OSMF based player to consume the streams and to do audio switch using late binding audio.
When I consume the Video with the Default audio everything works just fine. The problem is that when I try to consume the Video with the other audio track, the audio tack has a 1 second delay compared to the video.
I have tried to fix this by changing the configurations on the FMLE, but it doesnt seem to work. So I really want to know how does exactly AMS syncronize differents streams, in this case a video stream with a different audio stream.

First, what is the file format, and its specs. for the remote recorder?
Though the rates of modern cameras and digital recorders SHOULD match 100%, in the real-world, they seldom do. This make perfect syncing a labor intensive process.
One should do tests between the cameras and the recorders, to find out the % or error. Then, adjust their Audio to match first. As an example, one user in the PrPro Forum tested his Panasonic cameras, and his Zoom recorders, and found that the Zooms were off by 0.04% constantly. To correct this, he used the Time Remapping (with Maintain Pitch checked), and would apply that adjustment to all of the Zooms' files - perfect sync.
As for the Waveform not displaying for your remote recorder, did you allow those files to completely Conform (creation of the CFA and PEK files, the latter is the Waveform Display)? See this article: http://forums.adobe.com/thread/726693?tstart=30
Also, you should be able to increase the vertical zoom of your Audio Tracks, and hence any Clips on them, by hovering the Cursor over the junction between Tracks, in the Track Header, and when it turns into a = sign, with up/down arrows, click+drag. Then, you should be able to find commonality in the beginning, to sync up to. Tip: for this critical work, toggle the Snap feature OFF, with the S key.
Good luck,
Hunt

Two-way video chat with other (audio-only) participants?

Is it possible to have a five-way chat in iChat with
. - myself and one other participant via video, and
. - three other participants via audio only?
I know there's an option for one-way video conferencing, where only one person in a conference has video and the other(s?) have audio, but what about two with video and the others with audio?
And if we did this, could the three audio participants see the two video participants even if the three don't participate via video?

Hi,
You can start A One Way Video chat with a Buddy without a Camera.
You can add others up to the standard 4 people (you and three others) and some can be audio Only.
You do have to have a Mac of a G4/1Ghz dual or above and have a Upload speed of 256 k at the very Least (Apple Specs say 384k) although more is preferable when you are Host.
Ideally the Host should be the fastest Mac with the fastest connection.
Invite Camera able Buddies first then Audio Only Buddies by clicking on the green A/V icon they are showing in the Buddy list.

How can I keep my audio track, delete a short segment of video, and reinsert a new video clip, without changing the audio with the way it lines up with the original video?

How can I keep my audio track, delete a short segment of video, and reinsert a new video clip, without changing the audio with the way it lines up with the original video?

If you have either iMovie 09 or iMovie 11 you can do this easily using the Cutaway feature.
Go to iMovie/Preferences and make sure that the Advanced Tools are enabled.
Now you jut drag and drop the 2nd clip onto hte first clip at the frame where you want the Cutaway to start. A popup menu will appear. Choose Cutaway.
Here is a good Tutorial.
If you have iMovie 08, let me know. There is a way to do it, but it is more complex.

One-way video chat with iSight on Mac to PC via AIM

I recently bought an iSight camera for my powerbook G4. I am having trouble getting a video chat connected to my friend who is using AIM 5.5 on his PC. I am using AIM 4.7 for macintosh. Are there any tips on getting a one way video chat started?? he doesn not have a webcam

Hello Ivy,
Welcome to Apple Discussions.
Your PC pal should upgrade to the current AIM 5.9. If fixes some of 5.5's problems.
AIM for Mac has no video (or audio) capability). More info in the MSN, Yahoo, Win Messengers & iChat? FAQ.
See Using iSight with iChat AV for info on how to use your iSight for video chat.
Then, see Mac Video Chat with PCs for info on making video connections with PCs.
For more information on one-way video, search your Mac's
b iChat > Help > iChat Help
for "one-way video" (without the quotation marks).
The requirements for one-way video are the same as for two-way video except for one camera.
One-way video between an iSight-equipped Mac and a correctly configured PC is possible for most users. However, some users report that they can just NEVER get it to work. We do not know why that is. Adding any compatible USB webcam to the PC system (and "tuning" correctly after the addition) should let you make video connections if you are one who cannot make it work without a camera.

Can't start One-Way Video Chat with some Buddies

I have a MacBook running the latest version of iChat AV 3 (3.1.5 v440).
I just held a video chat with my father. He's also using the latest version of iChat.
Quitting that video chat, I also wanted to video chat with my mother in law. She's also running the latest version of iChat (on her non-intel mac: 3.1.5 v436). However, in my Buddy list, she shows up with a greyed out icon for the multi-chat. My audio and video chat buttons disable when I select her. There is no "Invite to One-Way Video Chat" menu.
We have both restarted our computers. We're both listed as Buddies of the other. No luck. My father shows in the buddy list as available for video chat, my mother in law does not.
I've previously been able to video iChat with her. What's going on?

5 minutes after posting, my wife noticed that one of the other computers in the house (with a different .Mac account on it) was 'ringing'. Apparently my mother-in-law had left an open audio chat invitation to another account, and that was preventing a new chat from starting. Sorry for the noise, hopefully this answer helps someone else.

One-Way Video Chat with Windows User

Hi - I have tried several times to begin a one-way video chat with someone using windows XP and AOL 9.0 (I have an iSight and iChat 4.0). She says that it says "connecting" for a long time but nothing happens. I came across the following website yesterday but have not tried any of its tips yet because of their complexity: http://www.ralphjohnsuk.dsl.pipex.com/page12.html#_Service
I was wondering if it is possible to have a one-way video chat with a windows user if they don't have a camera or a microphone. If not, is it possible to have a one-way audio chat?
Sam

I think your PC pal will need a microphone for one-way video to work, Sam.

When using a Foscam FI8910W IP Camera, how do I get the 2-way audio function to work? I have VLC as a video app in my applications folder. I am running OSX 10.8

Again, I am on a 2011 MBP, running OSX 10.8.4, and I use VLC as my default player. I bought a Foscam FI8910W Pan&Tilt camera, which has 2-way audio capability through the browser. I have looked online and the only people who have this camera who can also use their audio functions are those individuals who are on a PC running IE. The Foscam website says to fix this issue I must download VLC player. I had VLC before I ever heard of Foscam. Still no audio. When I sign onto my IP camera by inputting the IP address, the user name, and the encryption password, I can then view the camera. At the bottom, it has a URL that says (audio). Clicking this does only one thing - it tells me that I need a plug in to have audio support. The plugin is the VLC player. So I am back at square one. Please help.

I just went to the IP address to access my camera's software; however, there is no mention of audio settings or anything called ADPCM. The included software (CD) does not work with 10.8 - a fact left out by the manufacturer
In regards to .wav files as you had previously mentioned, I have only 6 (.wav) files on my Mac that could be located using finder. They are all involved with my MacMail application. I could not find any other .wav file.

3 way video conferencing with FaceTime?

Is it possible between Mac and two IPads?

Hi
"i guess that the aim with pc wont work out..."
It's been some time since I was last on here so not sure whether advice will work, Ralph Johns has a good website on getting a Mac to video talk to a PC using AIM/iChat. Whether it can do a 3-way is another matter, person with PC could have a look at http://www.ralphjohns.co.uk/page12.html & see if it helps. I have Skype but haven't tried any video calls with it yet so don't know if it can 3-way.

Problems with 1 way audio

So on and off maybe once or twice a year we have had one way audio issues pop up where incoming callers couldn't hear us but we could hear them. Reboot of the docsis modem for our pri service provider has always resolved this in the past. It started happening again intermittently a week ago (no config change on our part). I'm convinced my service provider has done something since nothing has changed with us but I'm having difficulties getting them to do anything. Attaching a log with a call we had issues with. Because its such an intermittent issue I cannot reliably replicate this issue. Heres a snippet. What caught my eye was the Bad protocol/sequence. What else would help to figure this out?
