However, you will need to disable audio each time you close and re-start a new session of VirtualDub. Unfortunately, VirtualDub always opens with this audio setting enabled. This will open a window similar to that shown below. This is where all of your video files and log files should be saved. With ongoing development and expanding usage, there may never be a final product. Use the book to get the background knowledge of the VirtualDub world, develop your skills to become totally comfortable with the software, and from there follow and adopt future developments with ease and excitement.
Keep this book in your library for continued reference. Whatever your main video editing software is and your personal video goals are, VirtualDub will enhance your videos. It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video.
It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is an Open Source tool and freely available to all. Various software tools have their place in the VirtualDub world, and we will cover them to some degree in this book. Use those that best fit your needs. My personal video efforts revolve around the world of Windows XP and its Movie Maker software: a digital video editor that, like VirtualDub, has a significant user base.
I can do lots without leaving Movie Maker, but video editors are always looking for that something special in their next project. When I have that yearning, I often turn to the world of VirtualDub to achieve it. I try to keep my writings focused on Movie Maker but felt honored when asked to write this introductory chapter.
VirtualDub is just too good a software package; writing about it is easy. Besides providing great editing touches, the world of VirtualDub builds bridges and links for those needing to work with files from different environments. VirtualDub started with a Windows AVI base for computer-based work, but has been branching out to other file types.
VdubMod, however, can handle the file type. Pictures are worth a thousand words and videos are even more so. VirtualDub supplements your main video editing software. The filters are those included in the software, provided by third parties, or developed by you.
The world of VirtualDub is wide open to use, learn from, or contribute to. A filter is anything that changes a frame or multiple frames of a video. You can apply one or many at the same time. You select the VirtualDub filter s , choose filter settings, and VirtualDub applies them to the frames of the input file as it makes renders a new file. The change might be the addition of text as you saw above, a color change, the addition of a logo in the corner, a rotation by a few degrees, cropping—anything you can think of wanting or needing to do to a video file.
Some changes fix problems and others enhance the video by achieving your desired effect.

Use this freedom to the fullest.
VirtualDub has been adopted whole-heartedly and developed further. Features continue to be added or developed and other related applications are being spun off. Think of this as a super version of VirtualDub. Each computer has many video and audio codecs on it to render or play an audio or video file. They work in the background, but sometimes there are software conflicts that need to be resolved. VDubMod with its expanded set of features will help. VirtualDub and VDubMod are applications you open as usual, and work with in windows.
AviSynth is a bit harder to grasp as it works more behind the scenes. You can use AviSynth in two ways. The easiest way is to simply change the extension of a video file to read. Open such a file and the frames will be obtained by AviSynth and passed to the default associated player, such as the Windows Media Player. The other way is to create a simple text-based script file using Notepad.
Enter some commands in the script file, give the script file an. There are some great and very established online websites and forums to get the latest in software downloads, follow continued developments, and get support.
Here are some:. In addition to the forums in English, there are ones for Spanish, French, and German. The overall administrator is the extremely active ChristianHJW. VirtualDub and related software are Open Source tools for capturing, processing, and encoding video.
Most tools belonging to the VirtualDub world will be covered to some degree in this book. We realize that different people use different software as their primary video editors and encourage readers to use the tools that best fit their purposes.
As the options and complexity for computers and software expand and the user community grows with them, so does the need for good tutorial information. That is the main reason for this book.
The concepts of digital video are easy to grasp. A common theme is to get a digital camcorder, copy the file into your computer, edit it a bit, burn a DVD, and watch it on your TV. The book will give you a working knowledge of the terminology involved, to understand more easily the online documentation and forum posts.
Key terms will be explained clearly as you read them. You will end up with the confidence and background needed to effectively use VirtualDub and its related software, and to experiment on your own or with the community of forum users. Read this book cover to cover, perhaps many times. Use it for reference as you continue to explore what you can do with your personal videos. The figure shows the new icons that will be displayed on your computer desktop.
The topmost icons open Virtual Dub and a test utility included with it which tests the performance of your hard drive.
This checks how well it can handle the demands of digital video work:. The lowest icon opens an AviSynth folder, not the AviSynth engine.
Use the icon to open a folder filled with the scripts you use to give commands to the AviSynth frame server engine. The engine stays under the hood and you call on it as needed by tweaking and opening a script. Many of the filters or their functionality may be absent in your main editing software, for example, an option to rotate a clip by 4 or 5 degrees for fine-tuning, instead of being limited to the degree increments.
VirtualDub is free to download and use. VirtualDub started with the processing of AVI files in the Windows environment, and there lies its strength.
Despite being focused on pre- and post-processing rather than editing, it has an impressive feature list. It is a useful standalone video tool and a great companion to full-fledged editors because:.
It also allows users to write their own video filters. You can take a captured clip, trim the ends, clean up some of the noise, convert it to the proper frame size, and write out a better one. Write your own, with the filter SDK. In addition to these features, version 1. For many users, video editing starts with the capture of video from a camcorder or other device to get the file to your computer. VirtualDub provides an option to do it, provided your device is compatible with Video for Windows.
Fractional frame rates. Instead of being forced to have a whole number of frames per second, VirtualDub will enable you to select for example Access hidden video formats which your capture card may support, but not have a setting for, such as x Also, ATI appears to be shipping their current devices with a WDM Windows Driver Model driver only; this can be used indirectly by VirtualDub through a Microsoft wrapper, but it is crippled in functionality and it also appears that the wrapper is buggy.
If it works for you, great. You may not need VirtualDub to capture your video, as your main editing software provides such features. In the days when Avery Lee created VirtualDub, previewing and rendering video was a time-consuming process. The software was designed for speed, both in its user interface and in the under-the-hood computer processing.
You can easily see his results as you use it. The latest experimental version 1. Whereas VirtualDub is the rock foundation and offers the ultimate in stability, much of the development into new areas has gone into VDubMod. An example is using an MPEG-2 source file. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. I basically started VirtualDub in college to do some quick capture-and-encoding that I wanted done; from there it's basically grown into a more general utility that can trim and clean up video before exporting to tape or processing with another program.
I released it on the web and others found it useful, so I've been tinkering around with its code ever since. If you have the time, please download and enjoy.
