Silent track for alternate audio?

HI, using DVDSP4, I'd like to have a silent audio track so a user can select that as a mute option. But how do i create a silent audio track? And does it have to be the same length as my video track?

Every TV sold today has a mute button. That is going to be much easier for people to use than going to a different audio track (and letting people know that one of the audio tracks is silent.)

Latency Issue When Multi-tracking For Webstream Audio

We are using Audition on a iMac 24". The input to the iMac is from a Yamaha M7CL via a Dante network, then through Audition, then sent via a Focusrite Scarlett 6i6 to Newtek Tricaster 8000. There is noticeable latency. The audio is not syncing with the video. Our video output is in real time, but the audio output from Audition is not. What could be the problem?

Sounds like we're on to something...
Do you have the Sound Output on your Mac set to the
Ozone and have the monitors connected to it as well?
The only way to get zero-latency in the headphones
during recording is to use the headphone jack on the
Ozone. Problem is though, USB audio devices are worse
than FireWire when it comes to latency.
yeah the sound output is set to the ozone and the speakers are connected to the ozone. there isn't any latency when recording, but when i play it back there is a delay. are you saying that i should connect the headphones into the ozone instead of the speakers? will this prevent latency during playback? please let me know and thanks for your help, thus far.

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.

Trouble with ATV and Alternate Audio Tracks / Chapter Markers

So I decided to "treat myself" and I got an ATV earlier this week. I for a long time have kept my movies and TV shows organized inside iTunes, and ATV seemed like the logical extension of that so that I don't have to sit hunched in front of my computer to get easily accessed media.
That being said, I've been reencoding a lot of my content for a higher-quality stream for my TV. And I'm encountering a few problems.
I'm using the newest Snapshot Build of Handbrake (which is pretty great) to create my files. I'm ripping them using the ATV preset, slightly modified:
- H264
- .mv4
- 3000kbps
- 2-pass encoding (turbo 1st pass)
- Native anamorphic resolution
- AC3 Dolby Pro Logic II mixdown
- AC3 Passthru
- Chapter Markers
The encoded file is passed through MetaX to add complete metadata and label the chapters. Then the file is stored on an external hard drive attached to my laptop, and added into the iTunes library (while remaining on the external HD, not copied into the iTunes Music folder).
And I end up with a great quality file that looks fantastic on my TV. However, I'm having some problems. I have no options for alternate audio or chapter selection on the ATV. If I open the files up in Quicktime, it has the options right there, plain as day, but they're nowhere to be found on the ATV.
The only thing I can think of is that it's because I'm streaming the files, not storing them locally on the ATV, but I can't find any yay or nay on that and I'm not quite sure why that would make a difference.
Can anybody lend a hand on figuring this out?

I tried to follow what you are saying but not enough information here. I can only tell you that using HB on .m2t files or mpeg2 files user must uncheck Chapters in HB preferences to be able to use Chapters forward and back with the Apple remote and ATV.
I know this does not address your problem but may give you some insight to help. When ripping I do check box chapter markers. Maybe its MetaX doing the problem I don't use that software.

Audio Commentary aka alternate audio file for movie.. How?

Hi folks,
I love this discussion group btw... awesome...
So, I've got my feature film done, we did a 1 week run at the theatre now, we are almost ready for our DVD release but want to do one of those really cool Director Actor commentary / alternate audio files for the movie. Is this done in FCE or iDVD? and any tips?
Best Regards,
Mark

... I think there is a workaround with FCE + iDVD.
You could duplicate the original sequence in FCE, then add your alternate audio to the timeline of the new sequence. (Record your commentary and add as a 2d audio track (say, a3/a4)). Raise & drop the audio levels appropriately across the length of your regular and alternate audio tracks. Export the resulting video to QT Movie and import it into iDVD along with your original Movie.
You will now have 2 versions of your Movie & can put them both in a single iDVD project (of course, subject to the limitations of the total length you can put on a DVD (~2 hours for a single layer DVD, ~4 hours on a dual-layer DVD.) Or just put them on separate DVDs if your Movie is too long to fit both on a single disc.

Compose Audio Tracks for Full/Minus Vocal Music Video DVD

Hi everyone.
I've recorded, mixed my song in Sonar, mastered the stereo audio file in Wavelab, edit video in Premiere CS4 for a dvd music video project. Anyone can help me how to compose the audio tracks so that finally listener can choose for full song or minus the main vocal with their remote controller.
Heard people telling about vocal on the right channel and music on left channel which will make the original stereo music mono. i'm trying to avoid this. any other way of doing that?...2 tracks together in a song, 1 full 1 without vocal? How do you do this?
Thanks, all the best everyone.

Mal,
One can do this very easily in Encore. While it's more an Encore question, let me try to tackle it here.
DVD-Video and BD, allow for multiple Audio Streams. These are user selectable from either a Menu, or the Audio button on the remote.
What I would do would be to Export your Sequence in elemental/elementary streams, i.e. one Video-only and then, in your case, two Audio-only files. One will be the full-mix with vocals, and the other with just the instrumental. These files can be either Exported from PrPro, or from your audio-editing program. There is one warning, that I will give you later on.
Now, you have three files: Video-only (silent), and two versions of your Audio. Import the Video-only into Encore, as a Timeline. Import the two Audio-only files as Assets.
In the Project Panel in Encore, drag one of your Audio-only files to that Timeline, where it will be Audio Track 1. Drag the other to that same Timeline, where it will be Audio Track 2. Audio Track 1 will be the main Audio, so you get to choose which one you deem more important, or which you want to be the default. The other, Audio Track 2, will be the supplemental Audio.
I would use a Menu, that had Buttons for the User to choose which Audio version they wanted. One Button would be specifically linked to the Timeline with Audio Track 1 chosen, and the second to that same Timeline, but with Audio Track 2 specifically chosen (drop-down in Properties Panel for those Buttons, will let you choose this). Most remotes will allow the user to choose on the fly, with the Audio button, but I would still do this Menu. I do similar, when I have DD 5.1 SS on Audio Track 1, and the DTS encoded version on Audio Track 2.
Then, just set up your other Menus, as is required.
For more Encore-specific questions, here is the Encore Forum. Some of the same folk there, as here, but there are some different folk, who only post/read there. One, Neil Wilkes is a major music DVD/BD producer, and knows his way around music mixing and authoring.
Now, that one warning mentioned above. Both DVD-Video and BD are centered around Video. If you are Exporting from PrPro, make 100% certain that your Audio is EXACTLY the same Duration as your Video, or slightly shorter. I usually leave about 1-2 sec. of silent Audio. Even 1 Audio Unit more in the Audio file can be an issue. Exact, or slightly shorter for the Audio. This holds for Exporting from your Audio-editing program too. Just check that Duration very carefully.
Also, if you are doing DD 5.1 SS, you might want to make sure that you have 02 sec. of silence, before the first note in your Audio, to give a DVD player time to lock onto the signal. This is more likely to be needed with higher-end DVD players. I always begin my Video with 02 sec. of Black Video and end it with 02 sec. of Black Video. My Audio does not begin until the end of the first, and ends before the end of the latter.
Good luck, and hope that this helps,
Hunt

Set default audio track for playback in Source monitor

So I'm an editor that is somewhat new to the profession and I am working on a project right now with close to 100 video clips in my project. Most of the clips have their audio recorded to track 2 but when I load the clips into the source window to find the footage asked for in my script there is no audio playback.
They play fine in the program monitor once placed in a timeline, because I have all the audio tracks are turned on until I do my mastering at the end of the project. To get audio playback in the source monitor I have to change the view option to audio waveform which shows a blank screen because there is no audio on track. I then go to the drop-down menu just below the video display and select track 2 at which point the audio waveform shows up and plays back fine. This isn't too arduous a process and isn't a great burden but it slows my workflow down considerably as I have to repeat the process for each new clip I load into the source monitor.
My question then is if there is anywhere in Premiere that I can set which audio track is the default audio playback track for clips loaded in the source monitor. I work on a lot of similar projects like this for the same client and they don't have the most rigorous standards for their shooters. This problem has come up before and will most assuredly arise again in the future so any tips/advice on how to fix this on my end would be much appreciated.
Thanks!

I'm not really sure.I don't do any shooting for the client and in fact don't have any contact with the shooters, we just do the post. They use a number of different freelance videographers all of whom have different equipment and procedures when it comes to formatting, orginization, etc.

Why can't I enable an audio track for recording? (It won't let me)

I want to record VO but PP won't let me...
On Mac OS X 10.10 Yosemite in System Preferences:
• Sound Input is set to C-Media USB Headphone Set (an Alesis usb mic...works fine for VO in Final Cut Pro 7)
• Output is set to Headphone port
In Premiere Pro CC Audio Hardware Preferences:
• ASIO Hardware is set to "System Default Input/Output"
• I have also tried "C-Media USB Headphone Set but this, too, doesn't work
• With "System Default I/O" selected, Output Mapping is set to "Adobe Desktop Audio" (only choice), and shows:
     • "Built-in Output: Headphones 1
     • "Built-in Output: Headphones 2
     • "C-Media USB Headphone Set: Front Left
     • "C-Media USB Headphone Set: Front Right
all four of these have a couple of square icons to the right.
In order to record VO, I first need to "enable track for recording" in the Audio Track Mixer. There are no in or out points set in my timeline and the tracks are not locked or solo'd or anything. So why can't I select the audio track I want to use to record VO? I click it but there is no response. I just want to know why this software is not doing what it's designed to do.

Is there a waveform monitor for the audio track in premier elements 13?

trying to fine tune audio,getting hits on the supplied sound tracks.
thanks
Dave

Thanks for the last two replies with details that turned around my approach to your question. It was not until your post 3 when you mentioned Music Scores did I realize that you were referring to Music Scores developed in the concept of being able to adjust their duration without altering music arrangement. You were not referring to non-Music Score music.
In the case of Premiere Elements Music Scores, I see no way to visualize their waveform in the Premiere Elements audio tracks. Double clicking a Timeline Music Score brings up the Score Properties dialog and not the Preview Window to inspect the waveform.
When "non Music Score" music is imported into Premiere Elements, it goes through a conforming process which automatically generates the cfa (audio) file and pek (waveform in audio track) file. And, these files are characterized by a waveform visible on the audio track with the appropriate audio display format. For each audio conformed, there are two files generated by the program, cfa (audio) and pek (related to waveform seen in the audio track).
When you drag a Music Score to the Premiere Elements 13 soundtrack, first you see "Generating" and "Conforming" and then Score Property dialog .When all is said and done, the Music Score is in the audio track with no waveform. If you go looking in the Media Cache Folder to determine if a cfa and pek set exist there after use of one Music Score (Drama in this example), you should find that the Drama conforming process generated 71, not 2 files, representing cfa and pek sets.
With regard to hard drive space...1 non Music Score file's conformed audio files might be expected to take up about 68.2 MB while one Music Score file's conformed audio files might
be expected to take up 263 MB.
Please take a look at what you have in the way of conformed audio in the Windows 7, 8, or 8.1 64 bit path
Local Disk C
Users
Owner
AppData
Roaming
Adobe
Common
Media Cache Files Folder
At this time I do not know the explanation for the absence of waveform in the Music Score representation on the Timeline audio track. Need to do more homework on that.
Please let me know if you confirm my observations above.
Thank you.

Exporting quicktime with 4 audio tracks for broadcast

Hi,
Does anyone know how to do this? i need to get a program out to a broadcast quicktime file with sync on 1&2 and M&E on 3&4, i have the sequence setup correctly as did a digi playout for the same thing which was fine. However, if i do 'export quicktime' with sequence settings i only get two audio chanels. If i go to quicktime conversion then all the drop down menus for multiple audio chanels are greyed out.
Any ideas?
Best,
GK

if i do 'export quicktime' with sequence settings i only get two audio chanels
how are up you assessing this? QT Player has only 2 playback channels and additional channels will be mixed down to those ... but if you press Cmd-J to open the movie properties you should see all 4 channels are there, or if you reimport your exported file back into FCP you'll see it contain the 4 audio tracks as exported ... if not then your export settings are not correct :/

Why doesn't itunes have 320 kbps listed for ripping audio tracks from CD as one of the default options?

Now I know you can ignore the defaults and create custom settings for ripping audio from CD's, but I'm curious why the good folks at apple didn't add 320kbps as a default. I figured it would be a default option since 320 kbps seems to be the standard for good quality when it comes to CD rips.
Am I wrong here? Anyone have any ideas?

Apple hasn't stated why it's not a default option.

Recording commentary track for video clip

I have recorded and edited some video clips and now i want to record an audio commentary to layer onto the audio of the video clip, like how directors do the alternate commentary track for a lot of dvds. It would be a recording of 2-6 people sitting viewing the video together with it's original audio.
Ideally,
1)I would mic each person and feed the mic into the computer to record them each as seperate tracks. I think stp can't do that, but garageband might?
2)I don't want the mics picking up the original audio of the scene they are watching, but I want the people giving the commentary to hear the original audio, as well as what they are saying and what the other people that are sitting in and recording are saying. So the only way I can see that working is to somehow have the original audio of the scene piped into headphones, along with the audio of all the other tracks being recorded.
So how is this all possible, either through my method or another method you could think of. And what equipment would i need, like a mixer or audio interface. If I can't do this natively in stp, than what can I use, like garageband, that i can import into stp for final mixing.

1) STP 1 can't do multi-track recording but STP 2 will be able to do it. In the meantime, yes, you can use GarageBand.
2) You're right, you'll need headphones.
If you want dedicated audio tracks for each one, you'll need an audio interface with multiple preamps like MOTU 8pre. You could also use only a stereo mic to record the whole room. That way, you could use an interface with only two mic pres and you'll need less mics too. And since it would be only one track, you'll be able to use STP. For this kind of recording, you'll want to use condenser mics.
