As for conversion time, are “MPEG-4 AVC”and “MPEG-4” the same?
AVC requires more time than MPEG-4 since it needs to perform more arithmetical operations and complicated calculations. MPEG-4 takes more than 120 minutes to convert 120 minutes of data. Although it depends on factors such as CPU specifications, AVC conversion may take aproximately 1.2 times longer than MPEG-4.
