Abstract

A method for converting video information from an incoming format to an outgoing format using a process free from one or more intermediary files. The method includes receiving video information in a first format and receiving a desired output media format based upon a first input and a desired TV standard based upon a second input. The method decodes the video information in the first format to raw video information in an uncompressed format and directly resizes the raw video information in the uncompressed format into a size associated with the desired output media format and the desired TV standard. The method adjusts the uncompressed format in the size associated with the desired output media format and the desired TV standard to a frame rate associated with the desired TV standard and encodes the uncompressed format in the size and the frame rate into an elementary video stream. A step of multiplexing the elementary video stream with audio information in the desired output media format and the desired TV standard to form video and audio information in a presentation format based upon the desired output media format and the desired TV standard is included.

Claims

1. A method for converting video information from an incoming format to an outgoing format using a continuous pass conversion process free from one or more intermediary files, the method comprising:

inputting video information in a first format;

directly converting the video information in the first format to raw video information in an uncompressed format;

inputting a desired output media format based upon a first input;

inputting a desired video presentation standard based upon a second input;

directly resizing the raw video information in the uncompressed format into a size associated with the desired output media format and the desired video presentation standard;

directly adjusting the uncompressed format in the size associated with the desired output media format and the desired video presentation standard to a frame rate associated with the desired video presentation standard;

directly processing the uncompressed format in the size and the frame rate into an elementary video stream; and

directly processing the elementary video stream with audio information in the desired output media format and the desired video presentation standard to form video and audio information in a presentation format based upon the desired output media format and the desired video presentation standard.

2. The method of claim 1 wherein the first format is selected from a digital file, a digital captured video stream, an analog captured video stream, and an internet video stream.

3. The method of claim 2 wherein the digital file is selected from an AVI format, an MPEG format, a DV format, a QuickTime format, Real Video format, Windows Media Player format.

4. The method of claim 1 wherein the uncompressed format is selected from RGB, and YUV.

5. The method of claim 1 wherein the desired output media format is selected from either DVD, VCD, and Super VCD.

6. The method of claim 5 further comprising inputting a quality setting based upon a third input when the desired output media format is DVD.

7. The method of claim 1 further comprising writing the video and audio information in the presentation format onto a disk media.

8. The method of claim 1 wherein the presentation format is selected from VOB(Video Object for DVD), VCD MPEG1, and SuperVCD MPEG2.

9. The method of claim 1 wherein the processing of the elementary video stream with audio information comprises a multiplexing process.

10. The method of claim 1 wherein the audio information is tuned to a desired frequency based upon the desired output media format.

11. The method of claim 10 wherein the desired frequency is selected from 48 kHz for DVD, 44.1 kHz for VCD and SVCD.

12. The method of claim 1 wherein the directing converting, directly resizing, and directly adjusting, and directly processing are performed free from one or more intermediary files.

13. The method of claim 1 further comprising processing the raw video information based upon video editing information based upon a fourth input.

14. The method of claim 1 further comprising processing the audio information based upon audio editing information based upon a fifth input.

15. The method of claim 1 wherein the processing for converting into the elementary video stream is provided in an encoding process and the converting to the raw video information is provided in a decoding process.

16. A system for converting video information from an incoming format to an outgoing format using an integrated computer software application, the integrated computer software application being provided on one or more memories, the one or more memories including:

a code directed to receiving video information in a first format;

a code directed to receiving a desired output media format based upon a first input;

a code directed to receiving a desired video presentation standard based upon a second input;

a code directed to converting the video information in the first format to raw video information an uncompressed format using a decoding process;

a code directed to resizing the raw video information in the uncompressed format into a size associated with the desired output media format and the desired video presentation standard;

a code directed to adjusting the uncompressed format in the size associated with the desired output media format and the desired video presentation standard to a frame rate associated with the desired video presentation standard;

a code directed to processing the uncompressed format in the size and the frame rate into an elementary video stream;

a code directed to processing the elementary video stream with audio information in the desired output media format and the desired video presentation standard to form video and audio information in a presentation format based upon the desired output media format and the desired video presentation standard; and

a code directed to receiving video editing information based upon a third input.

17. The system of claim 16 further comprising a code directed to receiving audio editing information based upon a fourth input.

18. The system of claim 16 wherein the integrated computer software application is a single integrated application.

19. A method for converting video information from an incoming format to an outgoing format using a process free from one or more intermediary files, the method comprising:

receiving video information in a first format;

receiving a desired output media format based upon a first input and a desired video presentation standard based upon a second input;

decoding the video information in the first format to raw video information in an uncompressed format;

directly resizing the raw video information in the uncompressed format into a size associated with the desired output media format and the desired video presentation standard and adjusting the uncompressed format in the size associated with the desired output media format and the desired video presentation standard to a frame rate associated with the desired video presentation standard;

encoding the uncompressed format in the size and the frame rate into an elementary video stream; and

multiplexing the elementary video stream with audio information in the desired output media format and the desired video presentation standard to form video and audio information in a presentation format based upon the desired output media format and the desired video presentation standard.
