VirtualDub: Video - Full processing mode


Step 2

From the "Video" menu, select "Compression" and select the video codec you wish to use (this would normally be DivX or XviD), and press the "Configure" button to configure the codec.

Step 3

Configure the codec for the first pass. For instructions on how to do this, please refer to our XviD Setup Guide and DivX Setup Guide. Press "OK" until you exit the VirtualDub compression options window and return to the main VirtualDub area.

XviD: First Pass


Step 4

From the "File" menu, select "Save as AVI".

VirtualDub: Save as AVI

Change the file name to include "1st pass" or something similar to indicate it is a first pass encoding file (don't overwrite your existing file). And select the "add it to job control" option. Save the file.

VirtualDub: Save Options


Step 5

Returning back to VirtualDub, again from the "Video" menu, select "Compression" and configure the same codec again. This, set the options for the 2nd pass. Press "OK" until you exit the VirtualDub compression options window and return to the main VirtualDub area.

XviD: Second Pass


Step 6

From the "File" menu, select "Save as AVI" again.

Change the file name to include "2nd pass" or something similar to indicate it is a second pass encoding file (don't overwrite your existing files). And select the "add it to job control" option. Save the file.

Repeat steps 5 and 6 for multiple passes (for example, in DivX, 2 or more passes are allowed).


Step 7

From the "File" menu, select "Job control". It should open up the job control window with a list of jobs that have been scheduled.

Each of the encoding passes should be listed here, and you can press the "Start" button to start the jobs - they will be processed in the order listed, so don't change the order. When all the jobs are complete, the AVI file from last pass is the one that you need (you can delete all the other passes).
