After conversion the file size is very large. Is it possible to reduce the file size ?
The size of the converted file depends on the size of the presentation, the size of the Audio / Video file, size of the narration file inserted and the properties selected for the Audio / Video conversion. If the video bit rate, frame rate etc is selected as high, then the size of converted file will go up. You can set a lower bit rate for a smaller file size but the quality of the output file will be drastically reduced.
