What Happens When You Convert AVI to WMV
Your AVI video is transcoded — video and audio streams are decoded and re-encoded into the WMV container. This is a lossy process that takes time proportional to the video duration.
Your AVI file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with WMV-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the WMV container and the file is saved
