Use of AUTOMATIC SCENE DETECTION on already existing huge file

Hello to all for the first time,
I have 6 HUGE already imported video files of my videos diary from Himalaya, so they are each 1 hour long files now and to edit the story I need to brake each of those HUGE imported files into individual clips!!!
Of course I can make new smaller clips manualy but my TIME SAVING question here is how can I make iMovieHD AUTOMATIC SCENE DETECTION work on already imported huge file? So that I just play the HUGE file and it automatically brakes the individual clips and makes different files/clips.
Got it?
Hope somebody into the know will read this.
Thank you

Thank you Sue,
Thank you for wellcome, great you want to help.
So I imported all my video (from Hi8 - remember) trough firewire in using iMovieHD ... and that is how I got here where I have those huge documents, each 20 Gigs, on my external drive.
so thats where I am at and I would like to RETROACTIVLY (I quess) use that automatic scene detection and out of one huge file (clip) get say 15 smaller clips.
Is that clearer
thanks again

Automatic Scene detection

Hi,
I just purchased a Powerbook and I am a new Apple user (converted from PC). I used to use a Pinnacle program but now I am very excited to try the iMovieHD which comes with the laptop.
Unfortunately, when I tried to create my first movie, I have a problem already with importing my images. My images won't split into clips. The program only shows everything as 1 long clip. I checked my preferences to make sure that the automatic scene detection feature is on. I didn't set the time and date of my camcorder.
My question is: (1) Is setting the date and time of my camcorder really criticial when you import the images? (2) eventhough the date and time is not set, i have several scenes which were shots at different time, but iMovie still didn't pick it up as a new clip, eventhough there was a good 5 seconds of nothing in the tape. How can that be? (3) if setting date and time the only way to do an automatic scene detection, what will be my next option to create several clips. Is there a way to do it manually (please...I hope this is not the answer).
Any tips are greatly appreciated. I already convinced my husband to convert from PC to MAC, hoping that for media stuff MAC is better and friendlier than PC. Please, show me that this is true.
Thanks in advance,
Amanda

Here is a link to an Apple Article about automatic scene detection:
http://docs.info.apple.com/article.html?artnum=61412
My clock was not set, but as soon as I turn the "internal clock" on, it shows the correct time and date right away.
I'm a bit confused now! If the clock is showing the correct date and time then it must be set and shouldn't be causing a problem with scene detection. With my camera (see details below), when I switch to record (standby) mode and select the menu item Clock Set, it shows the date and time, but there is no switch to turn the clock off or on.
It might be worth doing a short test recording with, say, 3 or 4 short scenes with a break of about 10 seconds or so between each scene. Import that to iMovie and see if the scenes are automatically detected (make sure the preference is checked first). If not, it might be worth deleting (trashing) iMovie's preference file - it's in your User (Home) folder under Library/Preferences and named com.apple.iMovie.plist. A new default preference file will be created by iMovie next time it is opened - you may then need to change some settings to your own preference, as required. Note that preference files in OS X can sometimes become corrupted - trashing them can often fix minor issues.

Automatic scene detection: Pros and cons

I am new to Premiere Pro. I have used Pinnacle Studio, where scene detection involves the storing of the scene information in a separate file from the captured video, which is stored in a single AVI file. I run Premiere on Windows, so as I understand it, the options I have are to capture my video to a single file, or to use scene detection, which creates one file per detected scene.
On the one hand, having a single file per DV tape is convenient. On the other hand, such a file is rather large.
On the one hand, using the scene detection feature will result in a large number of files. On the other hand, any files for scenes that will never be used can be deleted, saving disk space.
What I'm looking for is how others prefer to capture video -- either in one file or in multiple scene files -- and why you prefer to do it that way.

Scene detect.
I discovered the hard way long ago that each of my camera ops needs to set date/time on their camcorder or else it doesn't work (why they never set it, who knows...).
Add to that, if the little battery dies in the camcorder, it'll toss out the date and all saved functions - including white balance - each time the camera is turned off. Little things you learn....but anyway....
Yeah, scene detect, for all the previously mentioned reasons. I do multiple attempts at some shots, even in event work. By having individual files, I can toss the unused clips once I'm done selecting my shots (or at least set them as offline).

Why won't Firefox use the perfectly good Favourites folder already existing inWindows for the Bookmarks?

I am trying to compare different browsers to find a favourite. However I find it an unbearable nuisance that when I save a bookmark in Firefox I can't use it in IE9 or Chrome or any other browser.
This is a universal problem with browsers, they all make their own folders for bookmarks. Is there a good technical reason for this or is it only done to irritate the users.
There is a perfectly good Favourites folder installed by Windows. Why not use that one instead of clogging up the system with unnecessary extra folders.

1. There are a few services that will synchronize Firefox and IE bookmarks, along with some other browsers. <br />
Xmarks and CometMarks are two that I am aware of.
2. The PlainOld Favorites extension allows you to have Firefox use IE's bookmarks. <br />

Installer has detected an already existing oracle XE Instance on this Syste

I am trying to install XE in my lap top , but i am getting this error..
i have uninstalled earlier version and clean the registry and services, still i am getting the same error..
Kvl prasad

its called them 'rm' command :-)
its a bit easier with Linux as you can just remove all the directories, but having the files there shouldnt stop then re-installation as long as the rpm database is clean

Is it possible to update inside of an already existing .xml file?

I have a problem where I had to write an implementation of stack and make it read files and find errors inside the files. The only problem I am having is being able to then go into the file and fix the problem. Any chance anyone could help me out?
Thanks

Performance still isn't a primary design motivation.
I'll bet that "half the marks" are primarily aimed at adequately metricating (and documenting) performance (which can be very tricky)... and secondarily; introducing you profiling your application and redesigning & tweaking to achieve the required performance.
What performance requirements have you got? And how big (in bytes) is the data-file? Any statement of acceptable test-beds?. Any stated limitations on the design you can use to achieve it? Resource limitations? You know; that sort of stuff.
Can you post a more complete description of the assignment... or better a URL I can download the assignment package from. It sounds like an interesting exercise.
Cheers. Keith.

Scene Detect on Existing Clips

I have about a dozen 20-30 minute films I have captured to video tape and have loaded into my system. Because of some of the content of the tape, and historical/geneological images, I would like to break the films down to individual scenes and then attach metadata and other info to the scenes for later tracking or sorting. (Through Bridge)
With the films captured, though, it is a bit problematic. Making sub clips, or "converting to master clip" doesn't work (which was expected) but is there any way to use scene detection with the existing AVI file, to break the films down to individual clips? Or, is my best bet to re-capture the films with scene detection set to on and use those individual clips?
Thanks,
Bill

Yep, that's what I thought. I was thinking of scenealyzer as well...

Disabling Automatic Scene/Clip Detection in iMovie 8.0.5 (iLife '09)

I can't seem to find a solid answer to this anywhere.
As far as I can tell, iMovie has taken away the ability to disable Automatic Scene Detection.
See, I have several old videos that I've ALREADY edited and printed back to tape. Now I'm trying to re-import these old movies so that I can share them online.
However, when I import from my camera, iMovie is splitting up my edited movies into its own separate clips which are ordered by date.
It's quite annoying! As far as I can tell I would have to reorganize all of these clips and essentially re-edit them. I decided to just bite the bullet and reorganize my clips, however when doing this, the music in my original movies isn't exactly consistent when jumping between clips.
That said, is there any way to import video without iMovie automatically splitting up my clips???
Thanks!

Yes you would need QT Pro c/w QT7, however for much the same price you can upgrade to Snow Leopard which comes with QTX, which allows video, audio and screen recording without additional plug-ins.

A file with that name you specified already exists.

I'm using Deamweaver 8.0.1 on a Mac. My server is right next
to me and is also a Mac. Both Mac's are on OSX10.4.6
I connect to the server vis AppleTalk local network.
I guess I'm having a premission problem but whenever I try
and synchrnize I get an error like this:
Started: 6/14/06 8:39 AM
admin.php - error occurred - An error occurred - cannot put
admin.php. A file with that name you specified already exists.
File activity incomplete. 1 file(s) or folder(s) were not
completed.
Files with errors: 1
admin.php
Finished: 6/14/06 8:39 AM
I can manually copy files without error or insedent...
I have tried coping the entire site to the server, mannually,
again. I have deleted the site reference in Dreamweaver, quit and
then re-launch Dreamweaver and create a new site.

Update
I changed over to FTP connection with the host, just incase there was some weird wrong with my server. And FTP works fine from the command line, but Dreamweaver is seems goofed.
I "tested" the connection from the manage sites menu, its ok. The trouble remains when i upload files. Now, Dreamweaver says "error occured - An FTP error occured -- cannot put [file name] Access Denied. The file mau not exist or there could be a permission problem."
I have full access to the vsftp.conf file and I've allowed,
write_enable
local_mask
Any thoughs? Its entirely possible there is a simple explanation. I had this working before. Its just not working now.

Scene Detection plug-in options for Pr? Speed Grade just stops detecting

Hello all: We use Pr to cut and recut 30min to 3hr programs. I would really like to use a scene detect plug-in to help speed things up by cutting up the Line cut clip, so I can cut in multi cam ISOS.
I've tried to use Speed Grade and it just stops for no apparent reason after ~15 mins into either clip I've tried.
Plus, a lot of our deliverable clips are exported as MXF which won't work in Speed Grade.
Any suggestions for a plug-in for scene detection?
Thanks,
Tolbert

If you're in CC, what codec the clips are doesn't matter in a Direct Link workflow to SpeedGrade ... you should be able to use anything PrPro handles (though this is not always perfect, just mostly). Other than exporting say an EDL from PrPro to use Sg's scene detection capability? Hmmm. At that point, yea, MXF wouldn't work. Unless you proxied into Sg & re-conformed back in PrPro to "online" files. Boy, that's an old workflow these days!
I can certainly see why you'd want scene-detection automated if possible. That would take some time, scrubbing then working down to exact frames if there's a bunch of scenes per show. Maybe shooternz can pop in here ...

How to deal with "Error 1001. The specified service already exists" when install a service using installer package?

Hi everybody,
I wrote a "Class Library" project which is a service using Visual Stodio 2008 recently, then tried to use a Visual Studio 2008
Setup Project to install it.
Here is what I did for the "Class Library":
1. Finish the program.cs, Service.cs
2. Add Installer
3. Change the serviceInstaller so that "StartType" to be Aotumatic
4. Change the ServiceProcessInstaller2 so that "Account" to be LocalSystem
5.
6. Click in F5 (Start Debugging)
Here is what I did for the Setup Project:
1. Add the exe file built from the "Class Library" project to the Application Folder
2. On the Custom Action Editor, add the exe file from 1 to Install and Commit
3. Change the property of the project so that "RemovePreviousVersion" to be true
4. Click on F6(Build Solution)
Then I tried to run the msi file from the built of the Setup Project. Because I modified the two projects serveral times, I uninstalled the Class Library using "Control Panel->Add or Remove Programs" before I reinstall. Two things I notived:
1. After unstall, the registry was not cleaned up about the installed program
2. After several rounds install/uninstall, I got "Error 1001. The specified service already exists"
My questions are:
1. How to cleanup the registry when uninstall a program?
2. How to deal with the "Error 1001. The specified service already exists"?
3. Did I do anytbing wrong with the "Class Library" or the "Setup Project"?
Thanks a lot!
Helen

Hi Simon, not a problem!
I spent some more time on this and here are few more notes:
it is called Major Upgrade, when you are installing new version of the product upon a previous one and
MSI supports 2 strategies:
Strategy 1. Install a new version and uninstall previous one. (Install a new version right upon previously installed version (file merging is performed based on dll version number) and the delete previously
installed files)
Strategy 2. Uninstall previous version and install a new one (Delete all previous files and install from scratch new files.)
From the first look it seems that 1st strategy is weird and buggy. But, remember, MSI is great because it's transactional!!! That means that if once some of the phases (Installation, Uninstallation, Rollback, Comit) fails, your machine
will be reverted to the previous state and it'll be still functional.
Let's consider both strategies:
Consider you have installed product_v1.msi and you want to install product_v2.msi.
Strategy 1
1. MSI engine copies files from Product_v1 directory to TEMP directory
2. MSI engine merges files based on the assembly version (between v1 and v2)
3. Once merging is completed successfully it removes files in TEMP (RemoveExistingProducts action triggers it) and you got product_v2 installed, otherwise if it fails MSI engine revert machine to V1 and copies previous files from TEMP.
Strategy 2
1. MSI engine tottaly removes all files from v1.
2. MSI engine installs v2 files and if something goes wrong you cannot revert back, because RemoveExistingProducts allready worked out and MSI doesn't have files to revert machine back
I recommend to everybody to use Strategy 1 and leverage MSI transaction functionality. And you can set this strategies by defining sequence of RemoveExistingProducts action. See more info
here. So, I think it's not even a bug in VS as I said in the upper post it is default recommened behaviour.
AND, you got "Error 1001. The specified service already exists"
because if we follow Strategy 1 MSI engine tries to install Windows Service on top of the existing service and OF COURSE it fails MSI engine (StopServices, DeleteServices actions are executed before actual
installation and they look at ServiceControl table). In order to stop service first and delete them you have to fill ServiceContol table of the MSI (and then StopServices, DeleteServices actions will recognize what to they have to stop
and delete), like this:
*clip*clip*clip*
' see http://msdn.microsoft.com/en-us/library/windows/desktop/aa371634(v=vs.85).aspx for more info
' Update the Service Entry to stop and delete service while uninstalling
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD_Service', 'Service name', '160', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
' Update the Service Entry to stop and delete service while installing
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD2_Service', 'Service name', '10', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
*clip*clip*clip*
We can uninstall service first by following Strategy 2, but then we lose transactional support.
So, Simon did I encourage you to change your code a bit?:)
And, btw, if you don't want to change the strategy, please don't rely on SequenceID in MSI table, it can be change, you have to get the at the runtime.
Hope it will help to everybody!

here.
Truly yours, Marat
