Shortcut?? for moving entire audio or video tracks?

If I have elements/clips on audio track one and want to move the entire
track contents to audio track 3 for instance, is there a keyboard shortcut for tht?
I'm certainly aware you can use the track tool and drag it where you need it to go, but I was wondering if there are keyboard commands to make that happen?
Thanks.

If there is free space in the track above you can use the OPTION-UP Arrow.
Not sure how to get around doing it if there is stuff above the track you want to move.

How to isolate one audio or video track?

How to isolate one audio or video track? My premiere pro cc will only allow me to grab all 8 audio tracks and the video tracks at once when i import it and bring them into the timeline. When I click on one it highlights them all.

It helps to indicate what version of Premiere you have and whether you're on Mac or Windows.
If you're on 7.0.1 or later, then disable the Linked Selection button in the Timeline. It's the button to the right of the magnet (Snap). If you frequently want to toggle between linked and unlinked selection, you can assign a shortcut to the command
Also, you can select any track item by holding ALT while clicking. To select multiple individual track items (e.g., A3, A5, & A7 for a given clip), hold ALT+SHIFT while clicking.
And I believe Sarthak meant "Unlink" rather than "Ungroup." A/V clips are linked by default, so Unlink is generally available. Ungroup will be available only if what's selected is a set of clips that you manually grouped.

DO i need some extra hardware interface for receving both Audio and video

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 receving both Audio and video. im using code AVTransmit and AVReceive found from this site only

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...

MP4 movie error: No audio and video tracks found.

I recently move all my movies to a better performance hard drive. I imported the movies or playlists to iTunes. All movies were playing flawlessly until one day I get the dialog "Can't access file" ... I tried several things I encounter on this communities but the files still not played.
I can see all the files with their size on the hard drive, but when I try to imported or drag to iTunes, they simply not appear or they don't import at all.
In one of my test I found a dialog appear indicating "Error opening file: No audio or video tracks found" ...
I need the way to fix this situation, since I have over 500 movies on that drive. Would somebody help me ???
My email is [email protected], just in case you want to help me directly.
I can even pay a nice reward to the person who help me fix this issue. Seriously.

What is a better performance hard drive and what operating system? Kind of sounds like this should be posted to the morons over at Power Mac forum and the bozo that moderates it

Shortcut for moving between Panels on Modal Dialog boxes eg: Cell Options (OS X)

Is there an existing shortcut for moving between the tabs of modal dialog boxes. For example Cmd+Opt+'B' brings up Cell Options dialog but that is actually the shortcut for the "Text" Panel how can I navigate (using keyboard keys) to the other Panels {"Strokes and Fills", "Rows and Columns", "Diagonal Lines"}.
Note:
I realise I can create shortcuts for the Table…> Cell Options…> Diagonal Lines items but these shortcuts will not work in the context of the Cell Options Modal Dialogue box.

Hey Thanks.
For those who come looking b/s they had the same question:
As a bonus once one of these key sequences is pressed the tab heading area comes into focus so the arrow keys work for navigating tabs. So even for long list of Paragraph Style tabs which number greater than 10 still easy to navigate to them eleventh to someteenth ones.

Shortcut for moving forward and backward through Time Machine

It seems obvious that there should be keyboard shortcuts for moving backward and forward through time in the Time Machine. Anyone know how?

V.K. wrote:
it might seem obvious but AFAIK there are no shortcuts for that. use the mouse.
I can't imagine replacing a simple mouse click with something like
Cmd-Ctl-Shift-Fn12-page up
It's noticeable that the menu disappears when entering TM, meaning that the usual assignments of shortcuts in the KB menu have, at least for the present, unknown values, if any at all.
What kind of shortcut would take me back to December 25, 2007 anyway? The trackpad and trackpad bar work.
It's possible to open TM with a shortcut or script, but from there one is on the dark side.

Keyboard Shortcut for moving audio

Is there a keyboard shortcut to move an audio track the smallest increment? I am trying to sync audio with video and when I use the mouse to drag the audio left of right along the timeline, it jumps more than the minimum allowable increment.
Thanks for your help!

Welcome to the forum.
Neale has given you the "trick," that you need. Just do not forget to hit the S key again, to toggle Snap back on, when you go to do other editing, or things will not work as before.
Good luck,

Audio and video track strangeness

Hi,
I have a few camera angles that have 4 audio tracks associated with them, and other camera angles that are just one track...
I was attempting to stack all of my camera angles in fcp, so that I could sync the audio up for the various angles, and then cut between them and drag various pieces to the top video track (I assume this is a standard way of working).
Anyway, so the problem I was experiencing was, I had one video track with one audio track, and then the next video track above that had 4 audio tracks connected to it... So if I tried to take a slice of the 1st video track, and move it to the next track, the audio would go ontop of one of the 4 tracks....
I thought I could solve this by locking the video and deleting 3 of the audio tracks so everything would just have 1 audio channel (I dont need the other 3 for my editing purposes)... However, it still causes the audio to behave oddly and jump 2 tracks rather than one....
How do I fix this?? I don't even understand what is really happening here.
-p

Hmm after looking at it, it seems that what's happening is even though 1 audio track is assigned to each video track, FCP thinks that there should be 2 audio tracks? So when I move a video track to the next video channel, the audio is moving down two audio tracks instead of one...
Ok, so atleast I do understand WHAT is happening, I just don't know why.

In elements 10 audio and video tracks loaded but appear to be blank

running windows 7 with elements premiere 10... i have my audio and video loaded in the session but the tracks, 2 video with audio and one audio only track, appear to have no info. they play, but i cant see the wave file image. i need to see the file and be able to zoom in so i can line it up for syncing. i had at least the audio showing up at first, but somehow that seemed to disappear now? how do i fix this?

sadworld4804
The wave representation that you seek is in the pek file of the cfa and pek set for the audio. Did you let your audio go to completion for audio conforming before starting any work on the project?
But, I am suspecting something else which is easy to remedy and hope this is it.
1. Look to the left where it says track name, Audio 1, to see a speaker icon. You can toggle that to get 2 different "Audio Track Display Styles"
and
Please let us know if that was the issue, that is, the toggle choice for the "Audio Track Display Style".
Thanks.

Grouping Audio and Video tracks?

iMovie HD:
When I insert new clips or edit existing ones, my imported audio tracks lose sync with the clips that come after the place of edit. I am continuously manually re-aligning the audio which is very time consuming.
Is there a way to group or link Audio and video so the that imported audio will stay in sync with my clips?
I understand that it may not be possible for the clip I am working on, but what about the clips after the clip I'm editing?

Found the answer: "Lock audio clip at playhead"

Scripting: How To Tell Between Audio and Video Track?

When I create a collection of tracks from the main library and iterate through them, I get everything (in my case, video and audio tracks - no podcasts or TV shows as of yet). In checking the "Kind" class, they all have a value of "1".
How can I tell if a track I'm looking at is audio or video? Also, when I do start downloading podcasts and/or TV shows, is there a way to differentiate them also?
Thanks

**** so much for that on the Western Digitals. The interface is USB3
goodness, yes, youve got one of those OLD WD drives that has the controller board AND USB all as ONE SINGLE UNIT
write that HD off.
your "classique" HD here:
http://karlsbakk.net/bilder/WD10TMVW/wd10tmvw-2.jpg
tjk Wisconsin
So being USB3 doesn't tell us anything at all.
Yeah it does, it tells me its one of those OLD HD that was made with the "lets save 2 cents and make it all one piece" philosophical designs.

Locking Audio and Video Tracks in CS6 Tip

I discovered, again on accident :-) that if you hold down the shift key and select the Lock Track Icon on the audio or video, it locks, and unlocks all the tracks.
Works with selecting the "eyeball" icon, selecting all tracks and turning audio on or off for all tracks too
I found this pretty helpful on the project I am working on.

That's great. A simple adjustment and it works like a charm. Voila! One click of the mouse and the locks all snap like a year old bagel.
Thanks once more for your help, Tom.

HOW DO I FIND THE DRIVERS FOR WINDOWS 8 AUDIO AND VIDEO TO UNINSTALL?

I NEED TO INSTALL AND UNINSTALL WINDOWS 8 DRIVERS FOR AUDIO AND VIDEO SO THAT I MAY REINSTALL THEM, BUT I DON'T KNOW WHERE TO GO TO FIND THEM IN THE FIRST PLACE.
ALSO, IF I PURCHASE THE PROGRAM FOR UPDATING DRIVERS, WILL THAT PROGRAM ALSO INSTALL THE NEW AUDIO/VIDEO DRIVERS AND UNINSTALL THE FORMER ONES SO THAT I DON'T HAVE TO GO THROUGH SO MANY STEPS BY MYSELF. I FIND THE DIRECTIONS TO DO THIS FOR MYSELF VERY COMPLICATED.

Hi, I would like to assist you on this matter, however I would need some information from you first. I see that you are running windows 8. What is the make and model number of the computer that you are using? The windows 8 that you are using, is it a 32 bit or a 64 bit operating system? Please write back and I will be happy to do research on this issue.

Audio and Video tracks don't go up/down together EVEN when linked selection is checked!

I'm sure this is something really simple but I just can't figure it out. And it must be a button or a option that I've checked because it didn't use to do that a few days ago.
Basically, I have a clip on the timeline which has a video and an audio track. I want to move the video clip up to the next video track but I want the audio to move down to the next audio track too. Right now it's not doing that. Only the video file moves up to the next track and the audio clip remains in the same track. How do I fix that so that however many tracks I move the video up by the audio goes down by that same number of tracks?

Not sure how other NLES manage it but I think it would be a pain if audio automatically followed video in this respect. eg Blocked layers b'cos something is already there.
FCP &, and earlier behaved that way. I prefer the way Premiere Pro does it. You often do not need to move the audio to a different track when you move video to another track. I want to control the placement of audio and video separately now.
Thanks,
Kevin

Shortcut?? for moving entire audio or video tracks?
