Best Way to Straddle NTSC SD and HD

I've only worked in SD for a few years, but HD is looming large these days. I was wondering if anyone had any advice on taking existing SD projects and maybe setting them up in a flavor of HD so I can send out HD if necessary or SD.
Just make a new sequence with different settings? What about the newer ProRes deal? I'll do the learning, but wanted to get some direction first. Thanks.

Title 3D and any internal text generator will just scale up the titles...they will look better, and fit the project. Photos, they will be better too. You might need to rescan them if you scanned them specifically for SD.
You can't set a sequence setting that will accomodate both. The sequence setting you set will be the codec of that sequence. Put SD into and HD one, and it will scale to fit (or you need to scale it), and then render out as that codec. Software upconverts like this don't look good. If you need to work in HD, then deliver an HD and SD master...then work in HD and convert the final to be SD.

Not going to happen the way you want it to.
When you add a gift card balance to the Apple ID, it's available for the Apple ID.
Probably best to create unique Apple ID's for each... this will also make things easier in the future as purchases are eternally tied to the Apple ID they were purchased with.

What is the best way to safeguard my files and pictures before I send off my MacBook Pro to get fixed?

What is the best way to safeguard my files and pictures before I send off my MacBook Pro to get fixed? I am running Mavericks and use an AirPort Time Machine to back-up all my files.

Back up all data on the internal drive(s) before you hand over your computer to anyone. You need at least two independent backups to be completely safe. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you know how to restore to an empty drive.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.

In the page I simply referenced the facescontext directly... no need for a custom servlet.
public void createcookie() {
FacesContext fc = FacesContext.getCurrentInstance();
HttpServletResponse resp = (HttpServletResponse)fc.getExternalContext().getResponse();
Cookie userCookie = new Cookie("cookiename", "cookievalue");
userCookie.setMaxAge(-1);
userCookie.setMaxAge(3600);
resp.addCookie(userCookie);
return null;
public String readcookie() {
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
Map cookiemap = ec.getRequestCookieMap();
if (cookiemap != null) {
Cookie cookie = (Cookie) cookiemap.get("cookievalue");
return cookievalue;
For reference I could not get getCookies() method of HttpServletRequest to work.. it would only return JSESSIONID.

What is the best way to back up photos and videos to a dvd from iPhoto, not in iPhoto format but just in jpeg format to access on either windows or mac

what is the best way to back up photos and videos to a dvd from iPhoto, not in iPhoto format but just in jpeg format to access on either windows or mac

When you export the videos out of iPhoto be sure to select Kind = Original. Otherwise you'll just get an image file of the first frame of the video.

Best way to handle all erros and get performance(OCI)?

Hi there,
Im using[b] Oracle Call Interface to execute batch file process. But I have got a problem.
I set ExecuteBatch with the same number of commit time, i.e: 100, 1000 or just 10, for thats ok.
((OraclePreparedStatement)globalStmt).setExecuteBatch(commit);
And I handle executeUpdate to catch all SQL Exceptions. I made some proposital files with invalid erros but when I handle "executeUpdate" it�s doesn�t get the corrent error line, and puts out another line that is corret.
((OraclePreparedStatement)globalStmt).executeUpdate();
Check in the code I concluded that its always get the same sequence of commit number like the error line. For example, I have between line 1 - 50 a line error, this line is 31, but I set the commit time for 50, its show me that line errror is 50 wherever 31. But if I put setExecuteBatch with '1' so it can handle corret lines erros, but the system performance bring down. What is the best way to handle all erros and keep the perfronace?
Sorry for my english, I am not native. Thanks all.

So by doing this, everything will transfer and look exactly the way I have it on the old machine?
That is correct, if your old machine is Intel based after using MA the new machine will look just like the old machine. Here is information from Apple on MA, I'd recommend looking it over.
My recommendation is to answer NO when setting up the new machine when it asks "Are you moving from another Mac?" The reason being let you new machine get set up and run for a couple of hours to ensure it's fine. Then launch MA and follow the prompts, it's very easy and if you use a fast connection like FW it should go smoothly.

What is the best way to captue current date and time?

I got a field in table to capute current date and time...i am
using SQL Server.
field name datatype length
enter_datetime datetime 8
What is the best way to get current date and time and insert
to table?.
Is this way?.
<cfset curtime = 'dateformat(#now()#,'mm/dd/yyyy')&"
"&timeformat(#now()#,'hh:mm:ss')'>
This way looks like time is not entered correctly.
or any other better way?.

> get current date and time and insert to table?
You can use cfqueryparam
<cfqueryparam value="#now()#"
cfsqltype="cf_sql_timestamp">
Or as was suggested, set the default for your table column to
getdate(). Then you won't have to insert anything. Sql server will
do it automatically when a new record is created.

Given ipod from someone best way to delete their music and add to my apple id

Have been given ipod from someone what is best way to delete their music and then sync to my itumes and apple id

Hi Caz0,
You might want to try to factory reset the iPod to wipe it completely. Here's a link on how to do it: http://support.apple.com/kb/ht1339
As far as I'm aware an iPod Classic isn't tied to an Apple ID, therefore all you need to do is factory reset the iPod, sync your music library and plug in headphones, and you're ready to go!
Good Luck,

Best way to move the distribution and subscriber to another server

What is the best way to move the distribution and subscriber role to a different server for transactional replication?
Stop activity on the publisher then script out the drop and create and point to the new ones?
The publisher will remain the same server.
Thank you!
Paula

Hi Paula,
According to your description, you want to move distribution database and subscription database to a different server.
Firstly, to move distribution database without dropping and recreating the replication topology, you could follow the steps in the
article . However, the best way I recommend is to remove the replication, create the distribution on the new server, and recreate publication and subscription.
To make this process simple, you could use SQL Server Management Studio (SSMS) to generate scripts and run the scripts to recreate publications and subscriptions or drop publications and subscriptions as the screenshot below. Checking ‘To create or enable
the components’ generates the script for creating the publications and subscriptions, and Checking ‘To drop or disable the components’ generates the script for dropping the publications and subscriptions.
Firstly, please use SSMS to generate the script which is used to create publications and subscriptions.
1.Connect to Publisher, or Subscriber in SSMS, and then expand the server node.
2.Right-click the Replication folder, and then click Generate Scripts.
3.In the Generate SQL Script dialog box, check ‘To create or enable the components’.
4.Click Script to File.
5.Enter a file name in the Script File Location dialog box, and then click Save. A status message is displayed.
6.Click OK, and then click Close. For more information about the process, please refer to the article:
http://msdn.microsoft.com/en-us/library/ms152483.aspx.
Secondly, follow the steps above, check ‘To drop or disable the components’ to generate the script used to drop publications and subscriptions. Then run the script to drop publications and subscriptions.
Thirdly, please disable distribution using Transact-SQL or SSMS following the steps in the article:
http://technet.microsoft.com/en-us/library/ms152757(v=sql.105).aspx.
Fourthly, please create the distribution at the new server using Transact-SQL or SSMS following the steps in the article:
http://msdn.microsoft.com/en-us/library/ms151192.aspx#TsqlProcedure.
Last, please run the script generated in the first step to recreate publications and subscriptions.

Michelle Li

What is the best way to back up iPhoto and create disc space

what is the best way to back up iPhoto and then remove the iphoto folder from the mac book and onto the external apple time capsule

Two different questions
the best qway to backup is to use TimeMachine or other automatic backjup program
However this does not allow you to reduce space since a backup need to be a copy of your existing library and as soond as you changge the library you no longer have a backup and sooner or later the photos will be gone form the bakcujp too
You need to run the iPhoto library on an external drive or had a complete library on and external drive and a smaller library on yoru internal drive using iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ - to move photos between the two libraries
Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

What is the best way to resize a JPEG and store it in the Filesystem

Hi All,
I have developped a CMS System that renders JPEGs if it does not have the images available within the desired width already. Within my development setup (Dell Latitude D800 with ubuntu dapper drake) everything works fine and fast, as expected. Then I uploaded the application to my V20Z Server with 4gb RAM and the systems performance goes to its knees. I have hooked in a Java Profiler to see where the problem is, and it showed me that it is hanging wthin

This is a bad thing to do with JPEGs. You're better off just reducing the 'q' if you want a smaller/faster/lower resolution image. That way you're throwing away resolution intelligently. Using scaling you're throwing resolution away unintelligently. I was on a project where 40,000 images were scaled when they should have been low-q'd. Don't do it.
