MPEGRepair is a versatile MPEG encoding utility designed to both ease the difficulty of MPEG encoding and assist in the repair of troubled video streams. MPEGRepair is capable of handling HDTV and IMAX video frame sizes.

Tech Tips - Batch Operation

Overview

All PixelTools PC stand-alone products can be run in a batch mode to enable automatic processing of multiple files with out attention.

Demo of Capability

The batch mode can be easily demonstrated by opening a DOS command shell, changing to the directory where the PixelTools exe is located, and then typing:
MpegRep c:\Sample\Source.avi
This should cause the MPEGRepairHD application to fire up, encode your source file per your default parameters, and then shut down.

Details

Some important notes regarding running the batch mode:

The following commands are accepted:

MPEGRepair encode   -› MpegRep SourceFileName.Avi

{To encode SourceFileName.Avi using mpegrep.ini settings}

MPEGRepair decode   -› MpegRep –d SourceMpegFile.mpg
{To decode, split,fix, or analyze SourceFileName.Avi using mpegrep.ini settings}

MPEGRepair analyze   -› MpegRep –z SourceMpegFile.mpg
{To run the Quick MPEG Properties analysis of SourceFileName.Avi and save results in log file}

MPEGRepair append   -› MpegRep –a Append01.mpg
{To Append all MPEG files in the sequence starting with Append01.mpg}

ExpertHD encode   -› ExpertHD SourceFileName.Avi
{To encode SourceFileName.Avi using Experthd.ini settings}

TransMux multiplex -› TransMux SourceFileName.vbs
{To multiplex SourceFileName.MPG using Transmux.ini settings and file names}

TransMux split   -› TransMux –d SourceMpegFile.mpg
{To split SourceFileName.MPG into elementary stream using Transmux.ini settings and file names}

ExpertH264 encode   -› ExpH264 SourceFileName.Avi
{To encode SourceFileName.Avi int AVC file using ExpH264.ini settings}

ExpertH264 encode (verbose) -› ExpH264 –v SourceFileName.Avi
{To encode SourceFileName.Avi int AVC file using ExpH264.ini settings and outputting status logs}

The PixelTools application can be copied to any folder on your system. The application can be copied by copying all of the .exe and .dll files to another directory. This is often more convenient when running batch processes.

The PixelTools application will run using the parameters set in its local ini file. For MPEGRepairHD for example, the MpegRep.ini located in the directory where MpegRep.exe is located will be used for encoding and decoding parameters. If you want different parameters for each file to be encoded, you can create parameter files for each file and then copy the custom parameters to MpegRep.ini just before calling the application.   An example of encoding multiple files with multiple ini file appears below:

Copy File1.ini MPEGRepair.ini
MPEGRepair File1Frame0.Bmp
Copy Out.vbs File1.Mpg

Copy File2.ini MPEGRepair.ini
MPEGRepair File2Frame0.Bmp
Copy Out.vbs File2.Mpg

Copy File3.ini MPEGRepair.ini
MPEGRepair File3Frame0.Bmp
Copy Out.vbs File3.Mpg

The parameter file can contain the full path name of the output file(s). You can also have the application generate the output file name. If you set the output file name as “-“, MpegRepairHD will save the resultant output file in a file that is identical to the source file name but with a .vbs output.

The best way to create an ini file is to fire up the application, set your desired parameters, and then depress the Save As button. The ini file is a text file. You are welcome to edit the ini file, but it should be noted that some items are not used in the current application.

Advanced

You can use more advanced batch commands to add flexibility to your batch encoding.

To encode all files in a directory and move the resultant files to another folder, you could write a batch file called EncodeAll.bat which contains:

REM Process all .avi files in this folder
FOR %%j IN (*.avi) DO Call EncodeFile %%j

EncodeFile.bat can contain:

REM Encode Each file using the Custom.ini
copy Custom.ini MpegRep.ini
MpegRep %1

REM Move the resultant file to the k:\Output folder
move *.vbs k:\Output\%1

If your directory contains all of the dll and exe application files, the above two batch files, and your source files, calling EncodeAll.bat will call the EncodeFile.bat for each AVI file in your directory. The EncodeFile.bat will encoded the AVI file using the custom.ini parameters and then copy the resultant file (which can be named with the same AVI prefix but with .vbs extension.)
