EDIT DEVICE, BIT RATE CONTROL METHOD, AND BIT RATE CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable the material bit rate of a video material to be converted into a desired output bit rate in a short time with ease without causing image quality deterioration.

SOLUTION: A material bit rate concerning the inputted video material S1 of an edit object is compared with an output bit rate outputted by a bit rate determining portion 2. When it is determined that the output bit rate is larger than the material bit rate, meaningless data are added to material data of the video material by a null data inserting portion 5, and the material bit rate is converted into the output bit rate, thereby enabling the material bit rate to be converted into an output bit rate without deteriorating the image quality of the material data of the video material S1.
