Beginners guide to PC video editing

Written by Scott Brown

If you're new to PC video editing then knowing where to start can be a bit daunting, so hopefully this guide will point you inrepparttar right direction.

To start with you will need a few items of equipment

Camcorders/Video Decks

Depending on your requirements or aims there are number of different solutions to discuss, so i will split these up into separate sections.

1.If you are starting from new then i recommend buying a new digital camcorder, this will give you superior video and sound quality as well as making getting started in video editing very simple, so ideal forrepparttar 147473 beginner. There are thousands to choose from catering for various types of budgets.

2. You may already have an old video deck or camcorder which usesrepparttar 147474 old analogue outputs such as composite or s-video (be sure to check first what outputs you have). For this kind of setup you would need a capture card/analogue to digital converter, this is discussed in more detail further on inrepparttar 147475 article.

A PC for Video Editing

It is now possible to easily capture footage from your Digital Camcorder directly to your PC and edit it. If you looking at buying a new PC or building a new one thenrepparttar 147476 currents spec's are more then powerful enough ,a typical spec PC these days is a P4, 512Mb Ram, 80Gb HDD, Windows XP or something along those lines. You could always use your existing PC if you have one, but i wouldn't recommend using anything below a PIII 600.

Additional Hardware

When transferring video from your camcorder to your PC there are a number of additional things to consider depending onrepparttar 147477 type of camcorder your using. If you’re using a digital camcorder then all your need is a firewire card (also known as an IEE1394 card), a lot of current PC's have these as standard now, otherwise you will need to purchaserepparttar 147478 card separately. Some of these will come bundled with editing software such as Adobe Premiere but this really depends on which card you buy and how much you spend, once your camcorder is connected to your firewire port windows will automatically recognise your Digital Camcorder. If your usingrepparttar 147479 old analogue camcorder then you will also need an analogue to digital converter, seerepparttar 147480 section on video editing cards below.

Performance Tuning of a Daffodil DB / One$DB -JDBC Application

Written by Parveen Aggarwal

This article illustratesrepparttar best practices to improverepparttar 147413 performance of Daffodil DB / One$DB JDBC Driver. This article focuses on how to improverepparttar 147414 performance of a Daffodil DB / One$DB JDBC application using Statement, PreparedStatemnt, CallableStatement and ResultSet interfaces. Choosingrepparttar 147415 right statement interfaces and right methods according to your SQL query plays a vital role in improvingrepparttar 147416 performance of a JDBC Driver.

JDBC Overview

JDBC API provides standard set of interfaces to work with databases like Daffodil DB / One$DB, Oracle, Derby etc.

Connection interface encapsulates database connection functionality, Statement interface encapsulates SQL statement representation and execution functionality whereas ResultSet interface encapsulates retrieving data which comes fromrepparttar 147417 execution of a SQL query using Statement.

Following arerepparttar 147418 basic steps to write a JDBC program.

1.Import "java.sql" and "javax.sql" packages. (Import "javax.sql", if advanced JDBC feature like XA is to be used)

2.Load Daffodil DB JDBC driver (embedded or network JDBC Driver)

3.Establish connection to database using Connection interface

4.Create a Statement

5.Executerepparttar 147419 Statement

6.Retrieve results by using ResultSet interface

7.Close Statement and Connection

Choosing right Statement interface:

There are three types of Statement interfaces in JDBC to represent/execute a SQL query-Statement, PreparedStatement and CallableStatement. Statement is used for executing static SQL statement with no input and output parameters; PreparedStatement is used to execute dynamic SQL statement with input parameters whereas CallableStatement is used to execute dynamic SQL with both input and output parameters. One important thing to note about PreparedStatement and CallableStatement is that they can also be used for static SQL statements. However, CallableStatement is mainly meant for stored procedures.
