Help with Rendering/Finalizing Project Please?

Hi,
I am so new to this entire Adobe and video making that I've spent the last few hours pulling hair literally. I am hoping that some of you experts can take some time to give this novice some much needed guidance. Okay, I'm begging!
I recorded a wedding on a XHA1 MiniDV camera in 1080p 24fps. Captured the clips to PP CS4 which in turn makes them MPEG, I believe. Included in my project are addition clips imported from a Canon HF S21 also in 1080p 24fps and a Rebel T2i in ?? format. Didn't use too many clips from the rebel.
Anyhow, my project settings in PP are:
Video - Display format = Frames
Audio - Display format = Audio Samples
Capture Format = HDV
All Scratch disks are saved on to my desktop with 284 GB
Here is a picture of the sequence settings:
Again, sorry for the ignorance and stupiditiy. I am wondering what would help.
I am trying to burn it all with chapter markers and additional features to a DVD.
- What would be the BEST settings for exporting to Encore?
- Should I separate each section into a different sequence - would that help? For example, the pre-ceremony to one sequence. The ceremony to another. The reception to another. Or should I make new projects for each?
- How can I make my computer faster? Is it the memory, ram, etc? What should I do?
Right now, it has failed over and over in rendering in After Effects. It stops encoding when I export to AME. It says 158 hours for rendering in PP.
HELP!
I am using an iMac and here are computer specs (again, I am not even sure what to post to help you all help me):
Model Name: iMac
Model Identifier: iMac11,3
Processor Name: Intel Core i7
Processor Speed: 2.93 GHz
Number Of Processors: 1
Total Number Of Cores: 4
L2 Cache (per core): 256 KB
L3 Cache: 8 MB
Memory: 8 GB
Processor Interconnect Speed: 4.8 GT/s
Boot ROM Version: IM112.0057.B00
SMC Version (system): 1.59f2
Here is a pic of what I'm working on. I know the pic-in-pic feature probably doesn't help with rendering time either but 158 hours is killing me. In fact, when I go to sleep, I wake up to an error message where PP has closed.

leevang,
Your computer looks great. I wouldn't be too worried about the time PP shows for encoding etc.
I have found that right when I first start to encode a project, 73 hours or 12 hours is normal. Rendering is not necessary for encoding. However when I look back later, the time has dropped greatly.
Down to 2 or 3 hours. that's when I follow Jeff B.'s suggestions when I do a 2X scan.......

Need help with lost iMovie project.

I was creating an iMovie project for school and needed to save it on a USB, so I clicked on 'Export Movie' from the 'Share' options menu in iMovie. I chose the type I wanted it saved in (viewing for computers) and then a smaller screen in iMovie popped up saying it was exporting the movie, or something like that. It took about a good 30 minutes and my project was a 7 minute movie with film clips, music, transitions, ect. I exported this project to my USB but when it finished it wasn't on there and when I finally found it on the Mac somewhere, I went to drag it into my USB but it said it was full. I then dragged the project onto my desktop and tried to open it to see if it worked. When I did the iMovie icon jumped once and stopped. I clicked on iMovie and it was still there in the projects screen. I then decided to close iMovie and open the project again from my desktop to see if it would play like a normal movie but once I clicked it the iMovie icon jumped again, opened but my project that I was trying to open was not there anymore and wouldn't open from my desktop file. I cannot open it at all and view it, it has been lost from my iMovie. Is there a way that I can get it back? Really need some help with this.

What version of iMovie are you using?

Need help with a class project

OK, yeah. Change the Product constructor so that it takes scalar values (as opposed to arrays) -- a single int for units in stock, and single String for name, etc.
Then you can create multiple objects of that class, one for each CD or whatever.
It makes sense to hardcode values in the ProductTest class, but not really in the Product class. Your ProductTest class is almost there. You know how in the main method you create a single Product object with those arrays? Change it so that you have a loop. Loop through the prices, album names, etc., and create a Product for each set of values. Then put the Product objects in an array, or better yet (and if you've covered it in class) into a Collection like a java.util.HashSet or a java.util.ArrayList.
You said you wanted to make it take values from user input, rather than hardcoded lists. Once you've made the above change, move on to doing that. You can read user input with a java.util.Scanner. Or you can use a java.io.BufferedReader. Did the prof say to use one particular method or another?

PE4 with MF6 + trial version, help with Blu-Ray project

Is there a work flow I can read up on to accomplish this. I have a Canon HV20 HDV media. Use HD Split import M2T files into PE4 preset 1080i 30, render than save to desktop as same. The file is 1440x1080. I'm trying to make a high definition disk to playback on our Pioneer Blu-Ray player. Using Movie Factory 6+ trial version. Thank you.

Thanks for the reply Paul I appreciate that. Let me go back over what I've done so far as my last post was incorrect. Moved M2T clips from HDsplit into PE4 with a new project setting of NTSC-HDV 1080i 30. Saved to computer with a select MPEG pre-set HD 1080i 30. The short clip plays fine with WMP and properties is at 1920x1080. Using MF6+ I would like to burn my high definition movie clips to a standard DVD to be played back in our Blu-Ray player. Are these the right steps so far to import the clip into MF6+? I just recently downloaded the trial version but last night I found a help/info section in MF6+ so I plan on reading through that to get acquainted with their terminology.
Will I be burning a data disk to make this work? Maybe a couple of cliff notes to get me started so I can better understand how to do this. Your advice and suggestions are welcome.

Help with a Flash project im attempting

need a little help with the direction of where i want to go
with a flash app im trying to make. What it is that im doing is an
prototype application for a treasure hunt. (The prototype is so
that it can be used on a hand held PDA) the specification are
below:
A Treasure Hunt provides participants with clues which leads
them to discover a route and requires them to answer questions
along the way. Answers are scored as follows:
Correct answers 10 points
After 1 hint 5 points
After 2 hints 2 points
Incorrect answers -2 points
The 2nd hint gives the exact position on the map so that the
participant can keep to the route and not get lost.
I am going to design a Flash application (for the Flash 6
player only) which will run on a mobile device (PDA) with Windows
Mobile 2003 as the operating environment with a small screen
240x320 pixel resolution either portrait or landscape and 65K
colour depth. The device has a pointing device (stylus),
microphone, speaker and earphone socket. It is WiFi enabled to take
advantage of WiMax which will enable mobile devices to access the
internet over a wide geographic area such as a town.
I have considered providing the following functionality:
· Setup options eg: choose the Treasure Hunt from
alternatives, language options, accessibility options such as voice
output (could simulate voice command input)
· Present clues as either text or image (could simulate
voice output)
· Provide access to the internet eg: Google for
searching for information
· Keep a record of the score and allow participant to
keep track
· Present progress along the route on the map
–needs zoom in/out and/or scroll
· Save progress if a pause is needed
· Total time taken
· Provision for one or more sponsoring
organisation’s advert/logo (doesn’t have to be on
screen all the time)
Now ive been trying to think for the last couple of days what
the best way to create this is, but im having a really big mental
block on it. Now im not the best at flash, so it need only be a
basic application. I know how im going to do the map and then
language changes but thats about it at the moment.
So can anyone give me any advice on how to go about creating
this sort of thing, if you could give me any information, and where
would be the best place to start - i'd appreciate it greatly!

Thinking about it, (its late) because its only a prototype
that i have to create, it doesn't necessarily have to work, im only
just showing examples of what it can do so all of those features do
not have to work correctly. That sounds about right doesn't it? lol
jees im tired :D

Need some help with a counting function

Hello,
I use a simple sheet to organize the timetable of my patients. Now I'd like to count how many different patients I attend, without counting a patient twice if I attend him twice a week for example. My sheet looks like this:
Mon
Tue
Wed
Thu
John
Steve
John
Wesley
Mary
Harry
Deborah
Peter
Arnold
Carol
Chris
Mary
Sarah
Karen
Karen
Carol
Larry
Peter
So the answer would be 13, because I attend 13 different patients a week. Fields in blank should no be counted, the cell contend changes frequently.
A friend of mine tried to help me with a countif function but it didn't work out for me, it would count the fields left blank too.
Any idea?
Thanks, gabriel

Hi Gabriel,
Here's another, more generalized, approach that doesn't need adjusting for maximum number of visits/week at the cost of just a few more formulas. But only two tables!
Formula in A2 and copied down:
=ROUNDUP((ROW(cell)−1)÷$B$27,0)
Formula in B2 and copied down:
=IF(MOD(ROW(cell)−1,$B$27)=0,$B$27,MOD(ROW(cell)−1,$B$27))
The formula in C2 and copied down:
=OFFSET(Schedule::$A$1,0,B−1)
The formula in D2 and copied down:
=IFERROR(OFFSET(Schedule::$A$1,A2,B2−1,rows,columns),"")
The formula in E2 and copied down:
=IF(AND(D2≠0,LEN(D2)>0),COUNTIF($D$1:D2,D2),"")
The formula in F2 and copied down:
=IFERROR(IF(E=1,1,""),"")
The formula in F27: =SUM(F)
The value in B27 is 4, the number of day columns in the Schedule table. You would change that if you increase or decrease the number of days on which you see patients.
Column C is cosmetic, not needed in the calculation.
The error triangle means all of the cells in the Schedule table are already accounted for in the rows above.
Probably more compact ways to do this but it gets the job done.

I need help with my hangman project

I'm working on a project where we are developing a text based version of the game hangman. For every project we add a new piece to the game. Well for my project i have to test for a loser and winner for the game and take away a piece of the game when the user guesses incorrectly. these are the instrcutions given by my professor:
This semester we will develop a text based version of the Game Hangman. In each project we will add a new a piece to the game. In project 4 you will declare the 'figure', 'disp', and 'soln' arrays to be attributes of the class P4. However do not create the space for the arrays until main (declaration and creation on separate lines). If the user enters an incorrect guess, remove a piece of the figure, starting with the right leg (looking at the figure on the screen, the backslash is the right leg) and following this order: the left leg (forward slash), the right arm (the dash or minus sign), the left arm (the dash or minus sign), the body (vertical bar), and finally the head (capital O).
Not only will you need to check for a winner, but now you will also check to see if all the parts of the figure have been removed, checking to see if the user has lost. If the user has lost, print an error message and end the program. You are required to complete the following operations using for loops:
intializing appropriate (possible) variables, testing to see if the user has guessed the correct solution, testing to see if the user has guessed a correct letter in the solution, and determining / removing the next appropriate part of the figure. All other parts of the program will work as before.
Declare figure, disp, and soln arrays as attributes of the class
Creation of the arrays will remain inside of main
Delete figure parts
Check for loss (all parts removed)
Implement for loops
Init of appropriate arrays
Test for winner
Test if guess is part of the solution
Removal of correct position from figure
Output must be

Well i have worked on this and come up with this so far and am having great dificulty as to i am struggling with this class. the beginning is just what i was suppose to comment out. We are suppose to jave for loops for anything that can be put into a for loop also.

If anyone cann please help me i would greatly appreciate it. I have an exam coming up on wednesday also so i really need to understand this material and see where my mistakes are. If anyoone knows how to delete the parts of the hangman figure one by one each time user guessesincorrectly i would appreciate it greatly. Any other help in solving this program would be great help. thanks.

Hi thanks for responding. Well to answer some of your questions. The professors instructions are the first 2 paragraphs of my post up until the ende of the output which is You lose!. I have to have the same output as the professor stated which is testing for a winner and loser. Yes the program under the output is what i have written so far. This is the 3rd project and in each we add a little piece to the game. I have no errors when i run the program my problem is when it runs it just prints the hangman figure, disp and then asks user ot enter a letter. Well once i enter a letter it just prints that letter to the screen and the prgram ends.
As far as the removal of the parts. the solution is TEST. When the user enters a letter lets say Tthen the figure should display again with the disp and filled in solution with T. Then ask for a letter again till user has won and TEST has been guessed correctly. Well then we have to test for a loser. So lets the user enters a R, well then the right leg of the hangman figure should be blank indicating a D the other leg will be blank until the parts are removed and then You lose will be printed to the screen.
For the program i am suppose to use a FOR LOOPto test for a winner, to remove the parts one at a time, and to see if the parts have been removed if the user guesses incorrectly.
so as u can see in what i have come up with so far i have done this to test for a winner and loser:
//declaring a string variable
String data = " ";
// call the readString method
data = readString();
//retrieves the character at position zero
char temp;
temp=data.charAt(0);
int h;
for(h=0;h<4;h++)
if(temp==soln[h])
disp[h]=soln[h];
return;
if(disp[h]==soln[h])
System.out.println("You Win");
else
for(h=0;h<6;h++)
if(temp!=soln[h])
figure[h] = ' ';
return;
if(disp[h]!=soln[h])
System.out.println("You Lose");
Obviously i have not writtern the for loops to do what is been asked to have the proper output. the first for loop i am trying to say if the user input is equal to the soln thencontinue till all 4 disp are guessed correctly and if all the disp=soln then the scrren prints you win.
then for the incorrect guesses i figured if the user input does not equal the soln then to leave a blank for the right leg and so on so i have a blank space for the figure as stated
:for(h=0;h<6;h++)
if(temp!=soln[h])
figure[h] = ' ';
well this doesnt work and im not getting the output i wanted and am very confused about what to do. I tried reading my book and have been trying to figure this out all night but i am unable to. I'm going to try for another hr then head to bed lol its 4am. thanks for your help. Sorry about posting in two different message boards. I wont' do it again. thanks again, anita

Help with photos in project???!!

Hello,
I just bought an iMac about a month ago so that I could edit home movies and create DVD's of family vacations/events to share with my family. I have done this in the past on the PC with Pinnacle Movie Studio Software but it was buggy and more of a pain than it was worth.
So far pretty impressed with the iMac and FCE seems like it has potential. However I keep having problems with still photos in my video.
Here is what I have done - created a new project using the NTSC 48k template (not at my desktop now so I'm working off memory as far as naming). I captured all of my Sony Mini DV footage to the PC and dropped it into my timeline and edited it. Went smoothly. At the end of my movie I want to insert a "recap of the trip" using the still photos that I took with my digital camera and use the ken burns effect and transitions with music playing. My plan is to render and burn to DVD with iDVD for playback on a 1080p 60 inch plasma.
My photos are jpegs saved on my hard drive. I cropped them and adjusted color, etc in CS2. I didn't do anything as far as re-sizing them etc in photo shop as this is a little new to me and I didn't want to mess them up. Do I need to resize them for FCE? Seems like the program does this? If I need to resize them what size should I make them? Remember I want to be able to zoom in by creating the burns effect.
I have taken the photos and imported them into FCE. I drop them on the timeline and push play and everything looks great. When I start adding transitions with and applying the ken burns effect with key points the image plays fine by itself in the viewer window. However, when I watch the project play back in the canvas the stills appear very jumpy - not like a frame is missing in the render - the still literally looks like it jumps up and then settles back down. This is driving me nuts! FCE has to be able to do this smoothly. Can anyone provide me with a simple step by step on what settings I should be using for my sequences, etc to make this work. The settings really mess me up and I must be missing something.
I do have Tom's book but I can't find anything to help me with this issue. It is driving me nuts. Thank you in adavnce!

Thank you for the link. I went there and read the information. I still have questions:
Assuming I am using just still photos (let's keep it easy at first and assume no video) - what settings do I use for FCE under easy set up and for the sequence? Photos are jpg images shot with a digital camera that have been saved on my computer for a few years. I want to output my contents to DVD using iDVD and play back on a 1080p plasma tv.
Do I have to edit or resize the photos in photoshop first? It sounds like I can just import them into FCE and that it should work. I am not working with advanced photoshop images - just simple jpg images - no layers. The chart on page 2 of the link above says for 1080i - rectangular size N/A and square size 1920x1080. What does this mean? Is this telling me to resize my images to 1920x1080 before I import into FCE? If I want to use the Ken Burns effect and zoom should I double this to 3840x2160?
If someone can tell me step by step what they would do with the settings for FCE if they wanted to create a still photo slideshow with music, transitions and pan and zoom I would appreciate it. Again - source material is jpg images and I want to output to DVD using iDVD to display on a 1080p plasma tv. Also assuming that you had a standard landscape photo shot with a 4 megapixel camera what steps would you go through to prep it for FCE in Photoshop - if any?
Sorry that I am asking for a detailed example but I learn much better that way - after I am able to get one photo into an acceptable format for FCE the rest will be easy.
Has anyone actually created a successful slide show in FCE using transitions and the Ken Burns effect or do they get jitters in their photos as well - the image doesn't appear to flow smoothly.

Help with Starting My Project [Project AM]

I apologize in advance if this is not in the correct forum.
//The next two paragraphs are a rundown of why I am doing this project and my previous experience with Java//
Here's where my story starts, I've just started out a new year of school and I've been placed in a Computer Science (Higher Level) class, and it so happens that I am to be coding/programming in Java. I've worked with C++ in the past, and I've noticed that Java is quite similar, thankfully.
This Computer Science class is a two-year course, at the end of the two years I will have an external assessment (IB dossier) due. This gives me tons of time to work on this project, if you haven't noticed by now it will be an on-going project.
I know this project is going to take some time that's why I would like to start now.
//End of Rundown//
My project is called "AM" and in the end it will be an "instant messenger" (with your help of course).
The first thing I would like to establish in this project is creating a server program to accept connections and a client to connect to the server (text based). I would like multiclient connections to the one server program.
Now here's the question, what should I look into before starting this project, what Java technologies? What resources should I grab from the library or from the book store? Basically I'm asking where I should begin?
If anyone has any suggestions or even some personal experience with writing a program like this please contact me. I would really appreciate it. Also source code would really help in learning this, but I can probably search that on my own, thanks.

The easiest way to go about this is to use Sockets. You could also look into using RMI

Help with Java programming project

Hi,
I need help in writing this Java program. The purpose of this program is to read a variable-length stream of 0, 1 characters from an input text file (call it input.txt) one character at a time, and generate the corresponding B8ZS output stream consisting of the +, - , and 0 characters (with appropriate substitutions) one-character-at-a-time into a text file (called output.txt).
The program must use a class called AMIConverter with an object called AMI . Class AMIConverter must have a method called convert which converts an individual input character 0 or 1 into the appropriate character 0 or + or - of AMI.
It first copy the line to file output.txt. Then read the line one character at a time and pass only valid characters (0 or 1) to AMI.convert, which assumes only valid characters. The first 1 in each new 'Example' should be converted to a +.
This is what is read in, but this is just a test case.
0101<1000
1100a1000b00
1201g101
should now produce two lines of output for each 'Example', as shown below:
This should be the output of the output.txt file
Example 1
in :0101<1000
out:0+0-+000
Example 2
in :1100a1000b00
out:+-00+00000
Example 3
in :1201g101
out:+0-+0-
To elaborate more, only 1 and 0 are passed to "convert" method. All others are ignored. 0 become 0 and 1 become either + or - and the first "1" in each new example should be a +.
This is what I have so far. So far I am not able to get the "in" part, the characters (e.g. : 0101<1000 ) out to the output.txt file. I am only able to get the "out" part. And I also can't get it to display a + for the first "1" in each new examples.

Help with a simple project

I am new to writing in Java. I've been slacking probably more than I should be, and I have a small project that is due on Thursday for my class. Currently, I know how to write in C++ and C++ only. If someone could help me in writing the simple code for my project, that would be great.
The program is simple. It should allow a user to input a string of digits, and then output the sum of those digits.
For example; the user inputs 3563
the program would then output 17 (3+5+6+3)
Thanks for any help.

well, i think I figured out how to do this, except I am having a small error. Here is my code;
public class digitsum {
    public static void main(String[] args)
        throws java.io.IOException {
        int number = 0;
        int sum = 0;
        System.out.println("Enter an integer number: ");
        number = (int) System.in.read();
        System.out.print(+number);
        do
            sum = sum+(number%10);
            number = number/10;
        }while(number>0);
        System.out.print(" The sum is " +sum);
Now when I run the program, it is clear that it is correctly calculating the sum, but for some reason it converts the number which the user inputs into something else.
For example, here is a test run of my program;
Enter an integer number:
56
53 The sum is 8
56 is the number I input, and 53 is the number the program reads. As you can see, it says the sum is 8 (which is correct for 53, but I entered 56).
I am confused.

Help with binary conversion project

hey my assignment was to make a program that would say the binary representation of an int. i got my program working and im pretty sure it works for all negatives and 0. my question is can you guys help me with a way to do the same steps with for( or while( ? it seems like i went the long way doing this project and even tho it works theres probably a much simpler way of going about it. theres no interface or anything we just change the value of N and recompile it and run from command prompt so far in our class. thanks for the help

}Pete is right, in order to understand this you need to know how integers are stored.

Help with a Uni project

Im in the middle of a project for university. in its simplest form it is simply reading data from sensors and then controlling the movement of 2 dc motors. i'm having trouble however understanding what to do in labview. Im using version 9 with a Crio and an NI-9505 and NI-9205
My intial though was to create a new vi and target it that to the fpga.
in this VI i would use a flat sequence to intialise the motors, then measure the data multiply by various gains etc, to get my voltage out for my motors, then use this to set the duty cycle on a square wave to turn the motors
can any one offer any on this, or point me in the direction of a example which may help

What's the problem? Have you implemented this code? What's not working/not doing what you want it to do?
There are heaps of examples on ni.com. Try searching for them. Also, try searching the LV help for examples. Open the context help for each of your VIs and see if there are any examples included for them.
Have you thought about doing some ni training or getting a training manual?
