Does you product support Windows Media 9?

More advanced than the other converter, Video Convert Master supports Windows Media 9. Moreover we are watching for the new releases of Microsoft and include support for them in our programs. We will update our software with the tech advancement.

What are audio and video codecs?

A video or audio Codec (Compression/DeCompression) is a software component allowing to encode data to be stored on a media (CD, DVD, etc...) and/ to decode it to be visualized or heard. There are also so-called "hard" codecs usually embedded to camcorders or digital video players or professional and semi-professional video cards for video editing and composing.

What video formats are supported by Video Convert Master?

is short for "Audio Video Interleave", the original Microsoft file format for Microsoft's Video for Windows standard. It is an audio video standard designed by Microsoft and is apparently proprietary and Microsoft Windows specific. It is a format developed for storing video and audio information. Files in this format have an .AVI extension. However, Video for Windows does not require any special hardware, making it the lowest common denominator for multimedia applications.

MPEG Gives excellent compression with little loss in quality of the video. MPEG support three types of data - video, audio and streaming. There are a number of standards: among them there are two flavors of MPEG available today. MPEG-1 was designed to provide VHS video quality and CD audio quality at a combined data rate of 150 kilobytes per second. MPEG-1 is displayed at 30 frames per second in a frame that is 352x240 (horizontal x vertical) pixels in size. This allows relatively high quality video images to be stored in relatively small file sizes for playback across computer networks or CD-ROM delivery. MPEG-2 is the other side of the compression coin. It is a broadcast standard specifying a playback size of 720 x 480 pixels at 60 fields per second. Data rates can range from 2 to 10 megabits per second. This means large file sizes and data rates that require specialized hardware for playback. MPEG-2 is one of the core compression technologies for DVD. See the MPEG site for more information.

WMV This is Microsoft's new standard for audio and video which is closely tied with the Windows Operating System. The player is able to play Windows Media Video (.wmv) and Advanced Streaming Format (.asf) files, and also other formats such as QuickTime, AVI, MPEG and MP3. See the Windows Media site for more information.

RM/RMVB RealMedia provides one of the oldest and most widespread (85% of all web-accessing computers have RealPlayer installed) Web delivery formats. The RealMedia files (.rm) can be viewed using RealPlayer 3 and above. For more information see the RealNetworks site and their user information site.

MOV MOV is a file extension for QuickTime Video Clip. QuickTime is a video and animation system developed by Apple Computer. QuickTime is built into the Macintosh operating system and is used by most Mac applications that include video or animation. PCs can also run files in QuickTime format, but they require a special QuickTime driver. QuickTime supports most encoding formats, including Cinepak, JPEG, and MPEG. QuickTime is competing with a number of other standards, including AVI and ActiveMovie. For more information see the Apple site and their Support page.

What is bitrate?

Bitrate very often used when speaking of video or audio quality and file size -- defines how much physical space one second of audio or video takes in bits (note: not in bytes). The higher the bitrate, the more times per second the original sound is sampled, thus yielding a more faithful reproduction and better sound. When choosing an MP3, weigh the advantage of a higher bitrate against the size of the file. Generally speaking, a bitrate of 128 kbps or higher will provide satisfactory sound quality.

Constant Bit Rate (CBR) encoding maintains the same bitrate throughout an encoded file.

Variable Bit Rate (VBR) is an MP3 encoding method that's used when file size is not an issue. Unfortunately Video Convert Master decodes VBR but doesn't encode it.

Selecting the proper bit rate for your projects depends on the playback target: if you're making a VCD for playback on a DVD player, the video must be exactly 1150 Kbps and the audio 224 Kbps.

What is frame rate?

In basic terms, a video can be thought of as being made up of numerous snapshots, called frames. Frame Rate defines how many pictures eg. frames one second of video or audio contains, normally used acronym for framerate is fps - frames per second. Human eye can't see picture changes after the framerate is more than ~24fps.

Video files with higher frame rates show motion better but have larger file sizes. Typical frame rates are 29.97 for NTSC video (in American TV system), 25 for PAL (European system) video, and 24 for film. When exporting low-bandwidth versions, select a frame rate that is 1/2, 1/3, or 1/4 of the original frame rate. Setting a frame rate higher than the original frame rate will make the file larger but will not improve the quality.

Note that MPEG format only supports 23.976, 24, 25, 29.97, 30 frame rates.

My Windows Media Player will not play my newly converted DVD file. What should I do?

Windows Media Player requires installation of special plug-ins to be able to play DVDs. You can download them from the official Microsoft site.

What can I do with Video Convert Master?

How to report bugs?

Please email any bugs or suggestions to Generally, you will get our support within 24 hours.

How much is Video Convert Master?

The price for Video Convert Master is US$24.95 per license. But there is some discount for special customers such as Packet buyer, or back-customer. If you have several PC, or in one-PC & one-NB solution, we strongly recommend you purchase packet, because it is the highest benefit we can offered.

What is VBR?

Variable bit rate (VBR) encoding is an alternative to constant bit rate encoding and is supported by some codecs. Where CBR encoding strives to maintain the bit rate of the encoded media, VBR strives to achieve the best possible quality of the encoded media.
The quality of encoded content is determined by the amount of data that is lost when the content is compressed and decompressed. Many factors affect the loss of data in the compression process, but in general, the more complex the original data and the higher the compression ratio, the more detail is lost in the compression process.

What is Windows Media Format?

Windows Media Format is a proprietary format designed primarily for streaming audio, video and text from Internet servers to client computers. A Windows Media file can also be stored and played locally. Each Windows Media file contains one or more media streams that together form a multimedia presentation. Stream delivery is synchronized to a common timeline. The following list presents the key features of Windows Media Format:
A Windows Media file can be transported over any underlying data communication transport protocol. Windows Media Format does not specify the format of data packets for different network protocols.
Windows Media Format is scalable to any bandwidth. A single input stream can be encoded into multiple output streams within a single Windows Media file. Each scaled stream differs by the bit rate at which it can be rendered, and only one can be rendered at a time. The Windows Media server uses intelligent streaming to send the highest quality stream a client is capable of receiving.
The delivery and presentation of multiple media streams is synchronized to a common timeline. The media data inside a Windows Media file is time-stamped.
A Windows Media file can contain one video, one audio and one script stream.
A client does not need to store Windows Media-based content to play a multimedia stream.

Type of connection
T1 - 38 seconds
ISDN - 22 minutes
28.8 Time - 100 minutes

You will have only a few authorized attempts to download from the given URL (internet address). If the download is not completed in your first attempt, please try again.

Each Internet browser will save the program a little bit differently: When using Netscape to download, you will receive a message telling you that you have started to download a file of type/x application. Select 'Save File'. The directory that the download will default to is C:/Program Files/Netscape Navigator. With Internet Explorer, you will get a pop-up window that tells you the name of the file you have chosen to download. A second window will pop-up asking if you would like to 'open the file' or 'save it to disk'. If you select 'open the file' it will download it and kick off the install. If you select 'save to disk' another window will appear and you can save the file to the appropriate directory on your PC. Of the two options, we recommend 'save to disk.' That way you can run the install process at your convenience after the download is completed.
