.avi Files Multipling In Size When Added In in Toast 10 Posted May 10, 2009 · Report reply Your AVI files are most likely in MPEG 4 format whereas a video DVD must be in MPEG 2 format. MPEG 4 is much more highly compressed than MPEG 2 which is one reason it takes up less space. Your AVI's also may have a resolution less than the 650 or 720 x 480 that is standard for an NTSC video DVD. Toast should fit almost 3-1/2 hours of video to a video DVD. So one option for you is to add only enough video that fits within that time frame. It's best if you keep it within 2-1/2 hours for better picture quality. Another option is to burn your AVIs as a Data disc using either the DVD-Rom or Mac & PC format. In this case the AVIs may be able to be played without any re-encoding on a DVD player that is equipped for DivX playback. If you have a DivX-compatible player give this a try. However, not all AVIs are DivX playable, but many are. Hey thanks for your help tsantee, how will i be able to convert it to MPEG 2?
