How to Convert DVD to AVI

DVD, also known as Digital Versatile Disc or Digital Video Disc, is an optical disc storage media format, generally used for video and data storage. Physically DVDs are of the same size as compact discs (CDs), but has a significantly larger storage capacity.
DVD-ROM (read only memory) speaks to DVDs that have data that can only be read and not written; DVD-R and DVD+R (recordable) can record data only once, and then operate as a DVD-ROM; DVD-RW (re-writable), DVD+RW, and DVD-RAM (random access memory) can all record and erase data multiple times.
DVDs are of high quality and are easily transferred to a computer; however, the large file sizes and obscure file names are some drawbacks to using a DVD. Converting a DVD to an AVI or MPEG file provides advantages such as small and portable file sizes and your own file naming. Also, the files can be used for video editing.
Converting a DVD to AVI will eliminate issues which may arise if the DVD was copied in another format; these include reduced quality and limited capacity which can result from using a DVD burner. The conversion can be facilitated by software programs such as DVDx, Fairuse Wizard, avi.Net, and Nero.

How to Convert MP3 to WAV

MP3 is short for MPEG (Moving Pictures Experts Group) Layer – 1 and is a compressed audio format that allows for smaller file sizes with similar audio quality to PCM WAV format, the format found on normal music CDs. The MP3 is very common, more so because of its practicality and easy use.
MP3 compresses WAV audio to several times smaller than the original size. Files in WAV format are great in file size, with average size being 50MB. Because it is so large, it is hard to send WAV files through email or offer them for download on the Internet.
WAV files can be made smaller and converted to MP3 format through a process called encoding. When MP3 is converted to WAV, the process is referred to as decoding. When MP3 is decoded to WAV, there is no improvement in sound quality, the file just increases in size and can be read by common CD players. WAV format is essential for editing sound files.

How to Convert VHS to DVD

Video Home System also known as VHS is a video tape recording standard developed by JVC in the 1970s. It features longer playing time, faster rewinding and fast-forwarding, and a less complex tape transport mechanism. The open standard used for VHS technology allowed mass production without licensing costs. VHS would eventually come out as the winning video tape format, surpassing other home tape formats.
Despite its popularity so many years ago VHS is fast becoming archaic and as such persons who want to maintain their videos will need to preserve them in a more modern format. VHS tapes are also prone to damage and the actual film will begin to degrade over time. The average lifespan of VHS is three years whilst DVDs can last for at least 20 years.
Converting from VHS to DVD can be done by applying any of the following methods: use of a DVD/VHS machine, video camera, computer program, external DVD burner, video capture cards, and VHS to DVD conversion services.

How to Convert AVI to DVD

Audio Video Interleave (AVI) is a multimedia container format introduced by Microsoft as part of its Video for Windows (VFW) technology. AVI files can contain both audio and video data in a file container that allows simultaneous audio-with-video playback. AVI files support multiple streaming audio and video similar to the DVD video format. AVI is a common format for audio/video on the PC and can be supported by some standalone DVD players. It is not ideal for use as a general purpose container.
To play an AVI file on Windows the type of decoder on the computer must be determined to render the video. AVI files consist of a property called a FourCC, which has four letters, based on the kind of encoding used. VFW decoders then register particular FourCCs with Windows, letting it know that they can decode video in those formats.
AVI files can be created with no compression, resulting in extremely large file sizes, but with no loss of quality from the input video to the saved file. This also requires no codecs to be installed, either for saving or playback; as such it is advised to use a Lossless Compression format instead.
AVI files can be easily converted to DVD with the use of convertor programs accessible on the internet. One example is the Avi2DVD which is a graphic user interface that uses freeware tools and various freeware encoders or CCE to perform conversions. Other types of convertors are Convert Genius, Adobe Premier, Nero, and Pinnacle.

Things You Will Need

  • Computer with memory capacity for software downloads.
  • AVI to DVD convertor
  • Internet access
  • AVI files

How to convert word to PDF

A Portable Document Format or as it is more commonly referred to PDF, is a file format that was created by Adobe Systems in 1993 for the intended purpose of document exchange. PDF files are utilized to represent two-dimensional documents that are independent of the application software, hardware, and operating system. Each PDF file will include a complete description of a fixed-layout 2D document (and, with Acrobat 3D, embedded 3D documents using U3D) that often includes the text, fonts, images, and 2D vector graphics which constitute the documents. In some cases you may decide that you wish to convert a word file format into a PDF file. This might be done to create a file that can be protected from manipulation through editing of any kind. To achieve this goal you will need to acquire software that will allow this conversion. For this example Universal Document Converter will be used to expound the process. It is said to be the “most complete solution for the conversion of documents into PDF or graphical files”. It makes exporting files to PDF format a simple uncomplicated process that takes very little effort to complete.

Things you will need

  • A converting software for this illustration, as mentioned previously, Universal Document Converter will be used.
  • A text file created and saved in Microsoft Office Word.


  1. First you will need to download and install Universal Document Converter software onto your computer. Follow the instructions carefully to guarantee smooth download.
  2. Open the document that you wish to convert in Microsoft Word and select the Print option that will be shown under the File tab which may be found in the application’s main menu.
  3. Select Universal Document Converter from the printer’s list of options and then select the Properties button.
  4. Once you are on the settings panel, click on [Load Properties].
  5. Use the [Open] option to select [Text document to PDF.xml] and click [Open].
  6. Press the [OK] button in Microsoft Word Print dialog to begin the conversion process.
  7. Once the PDF file has been created it will be automatically saved to the My Documents\UDC Output Files folder by default, you may change this setting if you so desire.
  8. The converted document will then automatically open in Adobe Acrobat or another viewer associated with PDF files on your computer.


  • Ensure you have completely edited your file once you are ready to convert to PDF. Editing a PDF is not possible as it is read only format. However if you have already created the file as a PDF and have realized it needs to be modified, edit the source text and then convert once more replacing the old file by saving it as the original PDF file name.
  • For some Operating Systems most notably those that are Linux based, the PDF converter may not be necessary as the Open Office text editor already has the option to export a file as a PDF. To do this using Open Office you will only need to click on the export to PDF option and save the file in the desired location once conversion is completed.

How to convert WMV to MPEG

Windows Media Video or as it is more commonly known WMV is a compressed video file format used for a number of proprietary codecs developed by Microsoft. MPEG is another form of video compression that is applicable in most DVD players. Hence it is sometimes essential for a user to opt to convert WMV to MPEG for use in a standalone DVD player. To do this you will need an appropriate video conversion tool and the video to be converted. For this example Advanced X Video Converter will be used which is a useful Windows video tool that makes conversion an easy process.

Things you will need

  • Any conversion software for this example, as mentioned previously, Advanced X video Converter is used.
  • A video formatted as a WMV file.


To start you will need to obtain the required software. Once you have found the most desirable software install it on your system. Ensure that you follow all the instructions and that you read any manual or instruction guide that is included in your software.
If you are also using Advanced X video Converter then load the application and follow the steps listed below.

  1. Click the [Add Task] button that appears on the main window.
  2. Click the option [All To MPEG-1/MPEG-2″] on the [Task Window].
  3. Click the [Add File] button to add WMV files that you wish to convert to MPEG format. The
    source file may be AVI, DivX, Xvid, WMV, ASF, DAT and MPEG.
  4. Once this is done set the output profile to MEPG .
  5. Select the location where you would like to save the output file.
  6. Click the [Edit Profile] button. And choose an MPEG output format. Highlight [Disable Audio] if you do not wish to have audio on the ocnverted file.
  7. Usually you will not need to set width, height and frame rate as the application is
    capable of reading that from your source file. However, if it does not, look at the
    resolution of the source file and enter the value manually at the available option.
  8. If you wish to change the output resolution you may change width and height at the [Setting] option.

Do’s and Don’t

    When changing the resolution make certain that source resolution is not smaller than the output resolution as this will result in reduced video quality. For example if your source file is 320×240 and you change the resolution to 640×480 then the quality will undoubtedly be compromised.

  • To better understand whichever program you have chosen to use, experiment by clicking on all the options to familiarize yourself with the software.
  • To find the best conversion tool search the internet to find the most appropriate software. If you are a Linux or Mac user then search specifically for programs that are compatible with your operating system.
