I. Open Format Factory and find the avi video file you want to convert. Drag the video to your open format factory. Note that it is dragging. The red forbidden icon in the picture is the problem of the screenshot software, it won't be like that in practice.
Two, here you can click Configure to set it in more detail. A good feature is that you can adjust the volume of the converted audio. If you're not satisfied with the volume after you've finished converting and auditioning, you can come back and change it.
Three, click OK to place the task in the list automatically. Click "Start" to convert.
Note: Both rmvb, avi, flv, mp4, wma, mkv can be. Not just avi.
