Long / Chained Clips Break CS6

So, we've been trying to figure out what is causing the problems with mutlitple clips / multicam and the 'video not playing' problem.
It looks like it's a problem caused by chained clips (where AVCHD and Canon XF files are joined on import because they exceed 4GB).
CS6 seems to want to read the entire chain of files before doing anything, and any time you stop and start it appears it wants to go back and read the entire thing all over again. This causes a major bottleneck in the system which prevents video playing!
Any time you look at the file in the source monitor it shows media pending for a good while (while it's re-reading the chain) then things play fine for a while, but then it seems to want to re-read them over and over and things break.
If you lay the file on a sequence and ask CS6 to render it the dialog appears with zero frames rendered and sits for ages (again while the entire chain is read) and then takes off rendering. You can see the files being read in sequence in the Windows Resource Monitor.
The same thing happens on Mac so it's not a Windows only problem.
There "appears" to be no problem with single files that are not chained.
The behavior of CS5.5 appears to be different and this reading does not happen and you can play and scrub at will.
At this point it looks like we're going to have to put CS6 to one side (can I have my money back please?) or transcode any chained files - which obvisouly is not what editing native media is all about.
A quick fox for this would be much appreciated....!
< still testing >

As a follow up.....
I let these videos transcode overnight in to both XDCAMHD50 & also H264 in media encoder CS5.5.
I first replaced the AVCHD & Canon XF footage with the XDCAMHD50 footage and let it conform the audio (this is still a pain!). Playback was now perfect.
I repeated the exercise with the H264 (.mp4 @ 32mbit) and again, no problems with playback of multiple layers and / or multicam.
Just to be sure, I changed the files back to the original spanned clips and the original problem returned (no surprise - but was worth checking).
So, at this point the conclusion has to be that the spanned clips are the cause of the problem....... but I'm happy to look at any other causes Adobe engineers consider worthwhile.

Best workaround for editing long AVCHD clips in CS6?

Hi there, I've recently switched to CS6 and have run into incredibly long render times using native AVCHD clips (13 hours to encode a 30 minute m2v). After reading many posts it seems the issue I am running into is a known bug. So, my question is: is there a good workaround for this issue?
It sounds like this issue is only on long clips. Is it possible to automatically split the .mts files using another program (virtualDub?) prior to importing?
If transcoding from the native format is required (until the fix) what would be the best method using Windows 7 64bit? I have heard Avid's DNxHD is a good lossy codec, but I hate to do this if there is an accepted workflow I should learn instead.
Thanks for any advice!

How do I join multiple (short) audio clips into one single long audio clip in Premiere Pro CS5?

Hello,
The question is in the title but I'm wondering how I can join multiple (short) audio clips into one single long audio clip in PP CS5.5. I put all my short clips right next to each other and selected all of them to see what options are available by right clicking and using the toolbar options at the top. The closest that I got was to nest the sequence, but that's not what I really want.
I'd like to merge all the short clips into one single (long) audio file to use under the video.
Thoughts are welcome and greatly appreciated.
Thanks,
-Melvin

O.K. This is kind of fundamental and you will need to learn up on this fully ...but for now...
Make sure you have the WAB ( work area bar )covering the length of the audio clips. ( You do not need to select them)
Go to the File Menu> Export Media
You will be given all the Export Options. Choose Wave File
Select option for Export Work Area.
Choose where to export the file to ( HD location)
follow your nose from there....

BTW - Why are you taking the audio to Audition anyway? What are you going to do to it.

Why can I no longer drag clips?

I can no longer drag clips from the viewer to the canvas or timeline. When I the clip seems to disappear behind the canvas or timeline. "Show Overlay" is checked. The Edit Overlay box, which used to appear in the canvas, no longer appears. I use Final Cut Pro 7. I've edited a feature with no problem, so I'm assuming something has gotten switched off? Thanks.

Have you tried trashing your preferences? That is the usual first step when FCP begins to act in unexpected ways.
You can download Preference Manager (free) from Digital Rebellion and it will do it for you:

Your preferences will be reset to default settings the next time you launch FCP.

FCPX10.1.1 does not solve the problem with long-time clip editing!

OS: clean installed mac os10.9.1
FCPX: FCPX10.1.1
Project: 4clips, all of the clips is about 1 hour long (dvcprohd)
Disk: 900MB/S++
machine specs:
2*3.06Ghz 6-core
24GB DDR3
and I've tried these graphic cards:
K5000
and
2 5770
all get the same results:
If I double press the "L" key, the response of FCPX is too slow
If I do other operation like browse the clip, or import long time clip,
the FCPX will become too slow to browse the timeline.
I've found the FCPX like to generate audio waves of the clip and
there's no option to shutdown this! I've tried all the options in FCPX like
do not show the waveform of audio in preference and close the audio waveform in timeline
I don't think I can work the project with 10.1.x.
the 10.0.9 also has the 1st problem, but don't have the 2nd problem.
Another project: 2000++ 4K 50P clips(XAVC), but on FCPX 10.0.9, all of the clips is less than 40mins, always 20seconds.
though it will get slower when we import clips day after day,
it's much more smoother than 10.1.1!!!!!!
so,
I don't think we should update to 10.1.x for the little promotion of performance.
and 10.1.x also do not support nvidia K5000 card.
the render is slower than ait5700.....
I hope apple can solve the problem,
all of the above is just basic editing needs!
if the fcpx can not do even a long-time clip editing
why should I use it?

2 project:
1. 4*1 hour clips dvcprohd
that's the problem! I can not bear it.
2. 2000++clips 4K XAVC 50P project which I don't run on FCPX 10.1.1
I run it in fcpx10.0.9, it's fine, but slower when I imported more and more clips.
until now I can bear it.
the fcpx10.1.1 editing long-time clip has problem:
1.
it use 150MB/s harddisk speed to generate the waveform.
I have 900MB/s disk speed, so that's not the problem,
but it generate all the time!
1 hour clip's wavefrom generates for 1 hour without stopping, if I stop it , the fcpx crashed!
2.
when I skimming the clip for editing, the fcpx gets slower, always 2mins to response my operation.
3.
when I double press J or L key, the fcpx will need about 1 min to response.
the FCPX10.0.9 editing long-time clip problem:
the fcpx10.0.9 can handle the long-time clips, but also has very slow response when I doulbe press J or L key.

How long will the Photoshop CS6 Beta be active for?

Hi
I would like to know how long will the Photoshop CS6 Beta be active for. As a VFX Artist I will be testing CS6 in a production environment to improve workflow. Some of the features I want to be able to use won't happen for a few weeks yet as I'm awaiting content. I just basically would like to know that If I install CS6 now, will it expire in a few weeks or on 30 days? If it's very limited, I'd rather wait than have it expire on be before I can test it properly.
Thanks.

Many thanks. I should have mentioned that I meant for the video to be an irregular shape also. However from what you said I have worked it out so thanks again for quick response. Pete.

Please help me with this urgent viewing and editing question for a long video clip.

Hi, I have never used this software before and when I imported a 2 hours and 12 minute video clip of my sister's wedding into the system and added it as one sequence into the program it would only allow me to watch and edit the first 2 minutes.
Why is that and how can I rectify this so that I can watch and edit the whole clip?
Also, can such a long video clip be edited by trimming it and creating transitions where I see fit?
Thanks so much for your advice as I am feeling really stuck right now.

Exporting one section within a long video clip

Hi. I would like to work with a 2 minute section from a long video clip. One way to do it would be to import just that section into iMovie from the camcorder. But is there any way to accomplish this with a clip that has already been imported? In other words, can I take a section of a clip in iMovie and save it as a separate clip (or sub clip) that could then be edited, copied, exported or whatever? I am using iMovie 3.
Thanks.

Hi Howard
Yes there is some ways.
I would cut up the clip to get the required part.
Export this as DVstream via QuickTime expert mode - start a new iMovie project and import.
OR rather beeing lazy. I would export out neede part to my Camera and a new tape.
Use this tape in a new project

Deriving synced subclips from long unsynced clips?

When I capture my footage from MiniDV tape it often then has to be synced up in FCP. I'm sure there are steps to be taken to minimize this (or maybe not) but in the meantime I'm wondering how to deal with the unsynced footage.
I tried putting the whole long clip in a sequence and syncing it there. That works but then if I make subclips they don't stay together. The subclips taken from the browser to a different sequence paste linked but not lined up. It is the exact video clip and audio clip that I want but the respective tracks are askew from one another. Is there a way to fix the subclips and if not what is the most efficient workflow for deriving synced subclips from long unsynced clips?

Update: The workflow I've found works the best is to
1) sync up the long clip
2) use the razor tool to create my subclips using command-U and storing them in a temporary bin.
When I paste these subclips to my timeline they are the correct in and out points for video and audio tracks but they are out of sync to the degree they were in the original so rather than unlink them and line them up individually each time I...
3) take a big batch of the clips and put them in a temporary timeline
4) select all of them and unlink all of them
5) select all video clips and line them up with their audio counterparts
6) link them all back together
7) select all and drag them to a new bin, sometimes with "synced" in parentheses after the name of the bin to let me know these are the ones that are good to go.

Does itunes u descriptions no longer support line breaks?

Hi. I've got a faculty member that wants all of his course recordings available on itunes u. Previously, he would write a description for each session which I would post in the description field. Now, it appears that the description field no longer supports line breaks. Content generated prior to June is fine but all new content just runs on in one long paragraph. Anyone else seeing this problem?

The collection is in the iTunes U directory. I'll have to breadcrumb you there since I don't know how to direct link. So, go to the University of Washington, Social Science, T536 Taxation of Trans-Pacific Transactions. In the description, you will see it is one giant paragraph, no formatting. Before we were converted to the new template (apple template, not our own) in April, this was formatted properly. I've created new collections and they also suffer from this same issue so it isn't simply a matter of the conversion. Thanks you for your help!

Problem with Clip Usage and merged clips in CS6

The 'Clip Usage' drop-down menus don't seem to work in Premiere CS6 for merged clips. The info bar at the top of the project window correctly lists the number of times the viedo and audio from the clip has been used, and the downward-pointing arrow appears, but when you click on it... nothing happens. Same's true of the 'Video Usage' column in the main body of the project window. Non-merged clips work just fine.
Anyone know if this is just a problem with my project, or if it's a bug in Premiere? Had a lot of trouble with merged clips in CS5.5, and was hoping they'd be solved by CS6 - I've been using Creative Suite for a long time, and the lack of good merged clips support was always one of the challenges in persuading other indie editors to switch over from FCP...
Thanks!

...and the lack of good merged clips support was always one of the challenges in persuading other indie editors to switch over from FCP...
I guess they just have to weigh that up against the lack of support they got from Apple for FCP in its entirety.

Attempt to move main timeline from inside a movie clip breaks menu buttons.

I am attempting to have the main timeline move from a stopped position over a movie clip to frame 1, where my start menu is.
The code I'm using does move the timeline but in doing so it somehow breaks the 4 buttons I have in frame 1.
My code in the movie clip:
stop()
function replayMovie(event:MouseEvent):void
MovieClip(parent).gotoAndStop(1);
Menu.addEventListener(MouseEvent.CLICK, replayMovie);
My code in frame 1 of the main timeline:
stop();
function bo(event:MouseEvent):void
gotoAndPlay(21)
SoundMixer.stopAll()
espesp.addEventListener(MouseEvent.CLICK, bo);
function ho(event:MouseEvent):void
gotoAndPlay(31)
SoundMixer.stopAll()
espeng.addEventListener(MouseEvent.CLICK, ho);
function yo(event:MouseEvent):void
gotoAndPlay(41)
SoundMixer.stopAll()
engesp.addEventListener(MouseEvent.CLICK, yo);
function go(event:MouseEvent):void
gotoAndPlay(51)
SoundMixer.stopAll()
engeng.addEventListener(MouseEvent.CLICK, go);
The error output when I use my Menu button at the end of the movie clip.
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Any help would be greatly appreciated.

For the sake of space, I'll leave out all the package declarations and class declarations and just talk about the functions.
First, the Game class, it has two functions. The first one is the constructor function and it launches at the beginning of the game: First the Game function:
public function Game():void
//Game code goes here
}//Game
We want to listen for someone to click the mouse on the MenuPage, so lets create a new MenuPage and add a listener to the button contiained within it.
public function Game():void
menuPage = new MenuPage;
menuPage.startButton.addEventListener(MouseEvent.CLICK, startGame);
addChild(menuPage);
}//Game
You will notice that before I declared a variable var menuPage:MenuPage, but that's all I did was declare it. I didn't really make a new instance of it, I just set aside space for it. In the first line within the Game function, I'm actually turning that variable into a new instance of a MenuPage.
We don't have a picture of this imaginary menuPage instance, but lets' assume that in our MenuPage MovieClip in the library, we created a SimpleButton called startButton. Here, I'm adding an EventListener that patiently waits for someone to click that button. Once we receive that event, Flash is told to call the startGame function.
As you get better at this, you'll get into custom events, and the eventListener for the button will exist in the MenuPage class file, or even in another class file that you create just for the button. Something like StartButton.as But for now, we can do it as above.
Now the startGame function:
public function startGame(evt:MouseEvent):void
//Remove the start Page
//Add the zombie
//Add the gun
}//startGame
And we'll replace those comments with real code. It follows along with what we just did above.
public function startGame(evt:MouseEvent):void
zombie = new Zombie;
addChild(zombie);
gun = new Gun;
addChild(gun);
And we also want to clean up some by removing the menuPage, and throwing out the eventListener.
public function startGame(evt:MouseEvent):void
zombie = new Zombie;
addChild(zombie);
gun = new Gun;
addChild(gun);
menuPage.startButton.removeEventListener(MouseEvent.Click,startGame);
removeChild(menuPage);
}//startGame
Now our Game class is complete.
The Zombie Class
public function zombieWalk(evt:Event):void
this.addEventListener(Event.ENTER_FRAME,zombieWalk);
this.x = this.x + 10;
}//zombieWalk
Notice we've added a function to the Zombie Class.
The first function adds an EventListener to the zombie. We can use the word this and actionScript knows we're talking about the zombie that the class is written for. This listener fires off every frame. If our FLA file is set to 12fps, then 12 times every second it will call on the zombieWalk function.
The zombie walk function moves the zombie 10 pixels to the right every time the function is called.
On a more advanced level, you'll want to add animation in the MovieClip to move the zombie legs. You'll also want to use Timer events to space out how often the funtion fires and not ENTER_FRAME events. And you'll want to use a static constant to establish how far the zombie moves. We have it now set to 10 pixels, but that can get irritating if we want to change that value later. But again, baby steps.
And finally, the Gun class
public function Gun():void
this.addEventListener(MouseEvent.CLICK, fireGun);
}//function
public function fireGun(evt:MouseEvent):void
this.gotoAndPlay(2);
}//fireGun
First we add an EventListener for when someone clicks on the gun. Once this happens, the listener calls on the fireGun function.
The fireGun function takes advantage of the frames within the Gun MovieClip. Say we have three frames in the Gun MovieClip. The first is just a picture of the gun. The second is the gun with a flash coming out of the nozzle. And the third is the gun at rest again. The line this.gotoAndPlay(2) sends the gun to the second frame with the flash graphic.
For this to work, each frame in the Gun MovieClip has to have some stop and play commands.
But.. you said no code on our timeline!! Liar!
I know. This is the exception. You will need basic stop() commands and gotoAndPlay commands to loop animations. Any MovieClip that has more than one frame will need something to control it.
So our Gun MovieCLip has the following:
Frame 1: stop();
Frame 2: no actionScript... and I mean nothing, not even the words, "no actionScript"
Frame 3: gotoAndStop(1);
This will loop the gun to the beginning and wait for the next time the user clicks the gun.
Advanced features of the Gun class might include a Bullet.as sub-class that creates a bullet MovieClip to fly across the screen. Sound to play when the shooting takes place. Object collision detection to see if the bullet hits the target. And a means by which a custom event will tell the Game.as class that a zombie has been hit and it should be removed from the stage.
As you go down the rabbit hole of ActionScript 3, you will find yourself at a point where it's just a matter of getting the syntax right for all the built in functions and classes. Arrays, Loaders, casting variable types.. all that stuff will come.
I hope this has been helfpul. It's been on my to-do list for a long time. When I first started out, no one could provide me with basic answers for how all these classes and whatnot worked. After teaching myself AS3 for 2 years and reading a gabillion books, I think I've gotten to a point where I'm pretty comfortable with it all.

CC subscription just reverted to trial and no longer works (Flash CC / CS6)

After six months of using Flash CS6 (Creative Cloud), last weekend I decided to try the Premiere CC Trial.
That worked great and at the same time my Flash just switched to trial and became unusable (trial has expired already)
I've tried everything suggested by Adobe Technical team so far and more which involves the usual unistalling everything and reinstalling, logging out and in, cleaner tool, etc.
Still nothing will fix it.
I think I noticed an update to the Creative Cloud app at about the same time - I'm wondering if it is this causing the issue....
BTW, inside the Creative Cloud app, my account shows my valid subscription to both Flash CC and Flash CS6... and several other items show 'Install' rather than 'Try'
Please help!
(I posted this in another discussion as reply to a similar issue but the topic is flagged as answered so I'm guessing starting a new discussion is the right thing to do..)

Hi Ankit,
I am so frustrated by this - I have already lost days of my time trying to fix this. Not to mention the thrill of paying for software I can't use.
I have literally uninstalled and reinstalled everything I can think of a dozen times or more.. seen the post you mention already.
I have never changed languages... seen all the other stuff on the other thread too.
But guess what.. that is all pretty irrelevant because I was assuming that this was something to do with my particular machine.. but it isn't.
The proof? I went to my Mac which can also run the CC software and has been doing so just fine.. till.. you guessed it.. today..
Just tried that and the same thing has happened.. all reverted to trial.
So it is at your end... on your servers.. it has to be, right?
And all this nonsense you are dishing out here is just a massive waste of time. Well I'll need to fume in the corner for a bit longer I'm afraid.....
So.. trying to get calm and rational again...
The only thing I have changed on my account online is my id and password because I have literally tried everything I could think of... even that.
So my adobe id has changed.
I am signing into CC with the correct id and password.
Unless you are going to tell me that that has broken my Mac versions then please do let me know what on earth is supposed to be going on here...
Thanks
M.
