In order to convert an Audio Video Interleave (AVI) file into a Windows® Media Video (WMV) file you will likely need some type of conversion software. While converting from one file type to another can sometimes be simple, when it comes to video files the conversion is usually best handled either through an editing program or a simpler video file converter. These conversion programs can be found from a number of different software manufacturers, and freeware versions can be found for some of them. If you are looking to convert a large number of files, or to convert the files from AVI to WMV for use in a professional application, you may want to buy a conversion program.
AVI is a video file type that is technically a container format and not strictly a video and audio player codec. A container format is a type of file that allows for the playing of audio and video and properly synchronizes the two during playback. WMV is a file type developed by Microsoft® with the intent of being used for streaming video and audio content over the Internet. While WMV files can be saved and played through standard media players, they allow for excellent compression, making them ideal for online streaming.
If you are only looking to convert a single or few files from AVI to WMV with little manipulation of the file, then you may be able to find a freeware conversion program. Many freeware converters, however, will place a watermark over the image or otherwise limit how you can use them. For conversion of more files from AVI to WMV, you should consider investing in either a video editing program that will allow you to convert through it or a simple and inexpensive converter that will give you the features you need.
Look for customer reviews of programs that can allow you to convert video from AVI to WMV and ensure that other people have found the software useful. As you use the converter, you will want to make sure you select an output resolution that will suit your needs. You should also be sure to maintain the frame rate of the converted video, and use a bit rate that will have at least decent quality. Also, be sure to select video and audio codecs that will allow your converted video or audio to play in whatever player or streaming site you want to use.
A codec is a piece of software — and sometimes is used to refer to hardware as well — that serves to allow for the coding and decoding of a digital signal. Video files such as WMV use codecs to allow for easier compression, decompression, and playback of audio and video files. As you convert a file from AVI to WMV, you should ensure you use a codec that is widely supported, to allow your video to be uploaded, streamed, or viewed more easily.
