Help with splitting and arranging clips

Hi All,
Can some please help a complete noob by explaining their simple workflow for FCE HD from after capture to edit.
I am new to digital editing and am working my way through Tom's book but am a little confused in regards to arranging and organising my clips. I have a new project (My niece's 1st B'day party) which currently has 1 master clip (I think this is the terminology) with several (27) segments after running DV Start/Stop.
This is where I get confused. I want to arrange the segments into Bins, for example: Birthday girl, cake, games etc... But there is something about relationships between master clip, segments and subclips which I don't understand.
How is the best way to "cut up" (and is that the best way) the segments into smaller master clips so i can rename then, rearrange them and add comments in preperation for editing?
Sorry for the long post, but when you don't really know what you want to say you end up saying a lot
Cheers.

I don't use the Master/Subclip relationships. My method of sorting out various types of clip, by subject (your examples of "Birthday girl, cake, games etc...") is to slide (click, hold and drag) all obviously bad clips into V3 and ignore (mostly), and then slide all the Birthday girl clips on to V2 and move them sideways to group them closer together, then do the same for each other group. This leaves in V1 some shots such as establishing shots, closeups of decorations, departures etc. which you know where to put (eg., establishing shots at the beginning, closeups cut in somewhere where suitable as the editing proceeds). Next, I drag down and left or right various clips from V2 to V1 to their appropriate positions in order, leaving gaps between here and there to avoid having to move sets of clips left and right too often to make room. Then I set In and Out points in the Timeline (or Viewer) and close gaps between the clips within each set and see how that set looks. When all the material has gone through that process I check the whole video and make (usually) minor) changes, then do transitions and set audio levels, then leave it for a few days to look at it afresh.
Is this a bizarre method? What do you pros do?

Need help with buttons and fading clips

howdy,
I have 3 buttons on a stage that play 3 different movies.
While no button is pressed, there is a looping video on the stage
playing. When a button is pressed, that looping movie needs to fade
out and fade in the movie that button calls for. I have attached
script but it isn't working at all. Not sure where to go from here.
thanks for your help.

Hello again,
Now I'm completely lost. Where should I add that code in your
last post?
thanks.

Splitting and renaming clips in FCE4

How can I split a clip up into smaller clips and rename then? Whenever I try to copy or duplicate them I get the same copy for all. I was trying to change the name as well and it seems I can't make them independent of each other. Does anyone know how to do this?

Read through pp. 68-69 of the manual (aka the help file) "Copying and deleting items in the Browser". And pp. 943-950, "Working with Master and Affiliate Clips."
You can cut up a single clip into as many parts as you want. You can do this in the Viewer by setting IN and OUT points or on the Timeline by using the Razor tool. To rename the subclips created this way you have to make each of them an Independent Clip. ( *Make Independent Clip* or *Modify > Make Sequence Clips Independent*.) But read up on it before you do this, as you may create even more headaches for yourself if you're not careful when you do this.

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C
SAVING THE LIST DATA TO DB
DATA: L_WA(800).
LOOP AT T_TAB into L_WA.

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Help with count and sum query

Hi I am using oracle 10g. Trying to aggregate duplicate count records. I have so far:
SELECT 'ST' LEDGER,
CASE
WHEN c.Category = 'E' THEN 'Headcount Exempt'
ELSE 'Headcount Non-Exempt'
END
ACCOUNTS,
CASE WHEN a.COMPANY = 'ZEE' THEN 'OH' ELSE 'NA' END MARKET,
'MARCH_12' AS PERIOD,
COUNT (a.empl_id) head_count
FROM essbase.employee_pubinfo a
LEFT OUTER JOIN MMS_DIST_COPY b
ON a.cost_ctr = TRIM (b.bu)
INNER JOIN MMS_GL_PAY_GROUPS c
ON a.pay_group = c.group_code
WHERE a.employee_status IN ('A', 'L', 'P', 'S')
AND FISCAL_YEAR = '2012'
AND FISCAL_MONTH = 'MARCH'
GROUP BY a.company,
b.district,
a.cost_ctr,
c.category,
a.fiscal_month,
a.fiscal_year;
which gives me same rows with different head_counts. I am trying to combine the same rows as a total (one record). Do I use a subquery?

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.

I am trying to combine the same rows as a total (one record). Do I use a subquery?Maybe. It's more likely that you need a different GROUP BY clause, since the GROUP BY clause determines how many rows of output there will be. I'll be able to say more after you post the sample data, results, and explanation.
You may want both a sub-query and a different GROUP BY clause. For example:
WITH    got_group_by_columns     AS
     SELECT a.empl_id
     ,     CASE
                    WHEN c.category = 'E'
              THEN 'Headcount Exempt'
                    ELSE 'Headcount Non-Exempt'
            END          AS accounts
     ,      CASE
                    WHEN a.company = 'ZEE'
                    THEN 'OH'
                    ELSE 'NA'
            END          AS market
     FROM              essbase.employee_pubinfo a
     LEFT OUTER JOIN mms_dist_copy             b ON   a.cost_ctr     = TRIM (b.bu)
     INNER JOIN       mms_gl_pay_groups        c ON   a.pay_group      = c.group_code
     WHERE     a.employee_status     IN ('A', 'L', 'P', 'S')
     AND        fiscal_year           = '2012'
     AND        fiscal_month          = 'MARCH'
SELECT    'ST'               AS ledger
,       accounts
,       market
,       'MARCH_12'          AS period
,       COUNT (empl_id)      AS head_count
FROM       got_group_by_columns
GROUP BY accounts
,            market
;But that's just a wild guess.
You said you wanted "Help with count and sum". I see the COUNT, but what do you want with SUM? No doubt this will be clearer after you post the sample data and results.

Help with N8 and Adobe Premiere?

Hi, I am using Adobe Premiere Pro CS4 v4.1.0.
I recently got a Nokia N8 and am now trying to edit the video recordings, but am having some problems.
The phone records at 25fps 1280x720 using H.264 MPEG-4 codec, with sound in Stereo 130kbps 48 kHz.
When I create a project and load the .mp4 file into it, the first problem I see is that it reads it as 500fps and the video is only a second or 2 long.
I then interpret the footage to the correct 25fps, and the video then works fine. However, the sound seems to not be there.
I've noticed that due to Premiere interpreting it as 500fps, it thus only plays the first second or two of the sound when left as 500fps and plays all the video in that second or two, and thus when changing to the correct 25fps, it is therefore only the two seconds playing over the entire minute of video.
I also tried changing the file into other formats. The only other one that kind of worked was .mov. It allowed the sound to work perfectly, the video loaded at correct frames, however, when playing the video on premiere, it then showed black screen for most of the clip.
Have tried to find out about this online and installed a couple different codec packs and media players, but nothing helped with this problem in Adobe Premiere. However, the clip played fine in the media players, such as RealPlayer.
If anyone has any advice on this, it would be appreciated. I would prefer to fix this issue correctly rather than have to manually interpret or transcode the footage each time I want to edit it.
Btw, I also posted this question on a forum with Nokia N8 Users, and others also tried it out and had same or similar issues. They also tried on CS5 and it still didn't work.
*UPDATE* I just tested again to change the file from .mp4 to .mov by simply renaming it, and this time it loaded perfectly into Premiere. However, I have to do this on my XP computer, as my Windows 7 doesn't change the format of file by simply renaming it. Hence, I would still like help with getting it to recognise the .mp4 correctly though in the first place, rather than having to rename my files each time on the XP computer.

Moshpit84 did you utilize the uninstallers located in Applications/Utilities/Adobe Installers to remove your installation of Premiere Pro? Also what version of the Adobe Application Manager are you currently using?

Please Please help with JavaScript and Actions

Hello!
Is there a way to perform a saved Action from the Action Pallette using a JavaScript script? I know there is a way to do it with Visual Basic.
Is there a way to run a Visual Basic script from a JavaScript script?(which could be a potential workaround if JavaScript CANNOT call on an Action)
Is there a way to call on a JavaScript from an Action?
Here's specific information on my problem:
I am using Illustrator CS2 on a PC
I have written all of the JavaScript scripts that I need to perform various layer selection procedures and they all work perfectly. I have placed them in the Presets > Scripts folder so that they appear in my file menu.
I wrote a very long action that called on these scripts (using Insert Menu Item > then selecting the script by going File > Scripts) sequentially and did some selecting and copy-pasting and applying graphic styles in between scripts. The Action worked PERFECTLY and ran all the scripts I needed to an automated a process that usually takes me an hour in less than five minutes!
I saved the actions and saved the file.
After closing Illustrator all of the lines of the action that called on scripts disappeared! It seems this is a known bug...I currently know of no workaround.
Can anyone help with any of the following things:
1. Getting actions to SAVE the commands to run javascripts
2. Writing a JavaScript that runs an Illustrator Action
3. Writing a JavaScript that runs a Visual Basic script that runs an Illustrator Action.
I spent three days learning the basics of JavaScript (mostly by trial and error) and successfully wrote all the scripts I needed...I was overjoyed! But now that I've closed illustrator my actions to run said scripts do not work. PLEASE ADVISE!!!
Thanks in advance,
Matthew

try next
1)if possible split JS-code into 2 parts (before/after action)
2)make vbs script with contents
Set appRef = CreateObject("Illustrator.Application.3")
appRef.DoJavaScriptFile("C:\my1.js")
appRef.DoScript(Action As String, From As String)
'add wait while ActionIsRunning
appRef.DoJavaScriptFile("C:\my2.js")

When trying to insert a clip from the source material into the sequence timeline, using insert/overwrite function , dragging in the clip etc. any of the methods to bring the clip in from a given In and out point. Certain clips are failing and coming in as different in and out points. So the footage or clip/sublip in the source material comes in with the same lenght but the program is selecting a random different portion of the scene to put into the sequence. Please help. We are on deadline for a project :(. If anyone knows whats going on please help.

It sounds like you're running into a known issue with subclips from merged clips, which the engineering team is working on.
Unfortunately, there's no way to fix the subclips. Rather than making subclips, you could try one of the following:
Duplicate the merged clip in the Project panel and set the desired In/Out range for each instance. For all intents and purposes, this is the same as creating a subclip--at least a "soft" subclip, which is what you get when you deselect the option to Restrict Trims to Subclip Boundaries. Admittedly the workflow is not quite as efficient, but the results are the same.
If it's not essential to save subclips to the project, then simply load the merged clip in the Source Monitor, use In/Out points to define a segment, and insert the segment into your sequence, then repeat for the next segment of interest.

Help with Mathscipt and for loop

I have a code in Mathscript/matlab and I need to output the array out. One option is my first code,the other option is using a for loop, but I am only getting the last ouput out. I need to get the whole output out.
Any help.

What's the problem you're having ???

Help with encapsulation and a specific case of design

Hello all. I have been playing with Java (my first real language and first OOP language) for a couple months now. Right now I am trying to write my first real application, but I want to design it right and I am smashing my head against the wall with my data structure, specifically with encapsulation.
I go into detail about my app below, but it gets long so for those who don't want to read that far, let me just put these two questions up front:
1) How do principles of encapsulation change when members are complex objects rather than primitives? If the member objects themselves have only primitive members and show good encapsulation, does it make sense to pass a reference to them? Or does good encapsulation demand that I deep-clone all the way to the bottom of my data structure and pass only cloned objects through my top level accessors? Does the analysis change when the structure gets three or four levels deep? Don't DOM structures built of walkable nodes violate basic principles of encapsulation?
2) "Encapsulation" is sometimes used to mean no public members, othertimes to mean no public members AND no setter methods. The reasons for the first are obvious, but why go to the extreme of the latter? More importantly HOW do you go to the extreme of the latter? Would an "updatePrices" method that updates encapsulated member prices based on calculations, taking a single argument of say the time of year be considered a "setter" method that violates the stricter vision of encapsulation?
Even help with just those two questions would be great. For the masochistic, on to my app... The present code is at
http://www.immortalcoil.org/drake/Code.zip
The most basic form of the application is statistics driven flash card software for Japanese Kanji (Chinese characters). For those who do not know, these are ideographic characters that represent concepts rather than sounds. There are a few thousand. In abstract terms, my data structure needs to represent the following.
- There are a bunch of kanji.
   Each kanji is defined by:
   - a single character (the kanji itself); and
   - multiple readings which fall into two categories of "on" and "kun".
      Each reading is defined by:
      - A string of hiragana or katakana (Japanese phoenetic characters); and
      - Statistics that I keep to represent knowledge of that reading/kanji pair.Ideally the structure should be extensible. Later I might want to add statistics associated with the character itself rather than individual readings, for example. Right now I am thinking of building a data structure like so:
- A Vector that holds:
   - custom KanjiEntry objects that each hold
      - a kanji in a primitive char value; and
      - two (on, kun) arrays or Vectors of custom Reading objects that hold
         - the reading in a String; and
         - statistics of some sort, probably in primitive valuesFirst of all, is this approach sensible in the rough outlines?
Now, I need to be able to do the obvious things... save to and load from file, generate tables and views, and edit values. The quesiton of editting values raises the questions I identified above as (1) and (2). Say I want to pull up a reading, quiz the user on it, and update its statistics based on whether the user got it right or wrong. I could do all this through the KanjiEntry object with a setter method that takes a zillion arguments like:
theKanjiEntry.setStatistic(
"on",   // which set of readings
2,      // which element in that array or Vector
"score", // which statistic
98);      // the valueOr I could pass a clone of the Reading object out, work with that, then tell the KanjiEntry to replace the original with my modified clone.
My instincts balk at the first approach, and a little at the second. Doesn't it make more sense to work with a reference to the Reading object? Or is that bad encapsulation?
A second point. When running flash cards, I do not care about the subtlties of the structure, like whether a reading is an on or a kun (although this is important when browsing a table representing the entire structure). All I really care about is kanij/reading pairings. And I should be able to quickly poll the Reading objects to see which ones need quizzing the most, based on their statistics. I was thinking of making a nice neat Hashtable with the keys being the kanji characters in Strings (not the KanjiEntry objects) and the values being the Reading objects. The result would be two indeces to the Reading objects... the basic structure and my ad hoc hashtable for runninq quizzes. Then I would just make sure that they stay in sync in terms of the higher level structure (like if a whole new KanjiEntry got added). Is this bad form, or even downright dangerous?
Apart from good form, the other consideration bouncing around in my head is that if I get all crazy with deep cloning and filling the bottom level guys with instance methods then this puppy is going to get bloated or lag when there are several thousand kanji in memory at once.
Any help would be appreciated.

Usually by better design. Move methods that use the
getters inside the class that actually has the data....
As a basic rule of thumb:
The one who has the data is the one using it. If
another class needs that data, wonder what for and
consider moving that operation away from that class.
Or move from pull to push: instead of A getting
something from B, have B give it to A as a method
call argument.Thanks for the response. I think I see what you are saying.. in my case it is something like this.
Solution 1 (disfavored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          char theKanji = currentKanjiEntry.getKanji();
          String theReading = currentKanjiEntry.getReading();
          // build and show a flashcard based on theKanji and theReading
          // use a setter to change currentKanji's data based on whether the user answers correctly;
}Solution 2 (favored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          currentKanji.buildAndShowFlashcard(); // method includes updating stats
}I can definitely see the advantages to this, but two potential reasons to think hard about it occur to me right away. First, if this process is carried out to a sufficient extreme the objects that hold my data end up sucking in all the functionality of my program and my objects stop resembling natural concepts.
In your shopping example, say you want to generate price tags for the items. The price tags can be generated with ONLY the raw price, because we do not want the VAT on them. They are simple GIF graphics that have the price printed on a an irregular polygon. Should all that graphics generating code really go into the item objects, or should we just get the price out of the object with a simple getter method and then make the tags?
My second concern is that the more instance methods I put into my bottom level data objects the bigger they get, and I intend to have thousands of these things in memory. Is there a balance to strike at some point?
It's not really a setter. Outsiders are not setting
the items price - it's rather updating its own price
given an argument. This is exactly how it should be,
see my above point. A breach of encapsulation would
be: another object gets the item price, re-calculates
it using a date it knows, and sets the price again.
You can see yourself that pushing the date into the
item's method is much beter than breaching
encapsulation and getting and setting the price.So the point is not "don't allow access to the members" (which after all you are still doing, albeit less directly) so much as "make sure that any functionality implicated in working with the members is handled within the object," right? Take your shopping example. Say we live in a country where there is no VAT and the app will never be used internationally. Then we would resort to a simple setter/getter scheme, right? Or is the answer that if the object really is pure data are almost so, then it should be turned into a standard java.util collection instead of a custom class?
Thanks for the help.

Can anyone help with iPlayer and Sky Mobile?

Ok, I'm so close to giving up with this useless phone. There are 3 apps on my N97 which give me a constant headache.
BBC iPlayer
Sky Mobile*
YouTube
*I should point out that I only use Sky Mobile to set recordings on my Sky+. I do not use it for, nor have any desire to use it for actually watching Mobile TV.
All of these apps work absolutely fine over my home WiFi network. It's when I try to use them over 3G (my Vodafone Live! connection) that I start running in to trouble.
All 3 give me connection problems, errors, and simply refuse to load half the time when on 3G. I got so annoyed I just did a hard reset the other week, and magically all three started working again. However, now 2 of them are failing me again. YouTube (touch wood) is working fine at the moment, but iPlayer and Sky Mobile just aren't.
iPlayer sometimes works. But sometimes I get script errors (unable to load content), and sometimes it says something about checking my connection settings. I wouldn't mind but it's not actually possible to access any options for the iPlayer. Even in application settings there are no options you're able to set.
Sky Mobile simply flat out refuses to work ever on 3G. But it did after I did a hard reset for a couple of weeks, now it just stopped working! It wont even load. It just gives the error message 'Unable to connect to network - please check connection settings" or something along those lines.
I've tried so many different things. Tried setting my internet connections to 'always ask', tried setting it to default to Vodafone Live! all the time, tried setting my video streaming settings to WAP, all sorts. Every combination I can think of.
I just can't wait to get rid of this phone. I've put so many people off buying one. They see it and think it's all swish and cool, and I just say 'Don't. You'll regret it'. I can't wait for my contract to be up so I can upgrade to an iPhone now Vodafone have got them.
Can anyone help with these problems? Thanks in advance, but I don't hold out much hope...

About iPlayer.
Have a chat with Vodaphone. Streaming iPlayer over 3G IS allowed on Vodaphone contract, unlike my O2 contract. As long as your contract allows it, and you have the correct AP address, it should be fine. Vodaphone should be able to give you the setting.
Mine only works over Wlan.
FWIW, "... streaming over 3G is not currently available on iPhone handsets on any mobile network".
p.s. Just to be clear. You say "Tried setting my internet connections to 'always ask', tried setting it to default to Vodafone Live!".
iPlayer uses the Nokia browser "Web". So that's where you should make the setting "Ask when needed". It should then offer you the choice of whatever you've set in Destinations> Internet> then select whatever you've chosen as your GPRS connection.(as advised, or sent to you by Vodaphone).
