To select a video you would like to convert hit the Browse... button next to the Input File Name field. In the opened Windows Explorer window browse for the necessary video file:
Press the To AVI, To MP4, To MOV or To 3GP button on the Formats tab of the Main Toolbar to assign the output format that can use multi-pass codec for conversion without doubt:
Suppose, you set your choice on the AVI output format. Click the Advanced >> button:
The Conversion Options tab will appear. Drop down the Video Codec combo box in the Output File section and assign the codec that supports multi-pass conversion:
To start the first stage of multi-pass conversion press the Advanced... button placed to the right of the combo box by means of which you assigned the codec:
Twopass - 1st pass:
Multipass - First Pass:
No matter which codec you assigned, click OK in the codec settings window to save changes.
Press the Convert now! button in the main window and wait until the analysis process is completed:
Open the codec settings window again:
Drop down the Encoding type combo box and choose the Twopass - 2nd pass option. You can define which criterion is a limiting factor – bitrate or the file size. The button labeled as Bitrate is shown by default. Set a necessary value:
If you want to rely on the quality depending upon the desired file size then click the Bitrate button again to switch into the appropriate mode and input a proper value for the edit box right to the button which is labeled now as Target Size:
Drop down the Encoding Type combo box and choose the Multipass - Nth Pass option. And define the desired bitrate by means of moving the slider of the Target Bitrate track bar:
Whatever codec you chose, click OK in the codec settings window to save changes, you will see the Conversion Options tab anew. Set the necessary parameters for the forthcoming converted video in the Output File section.
Before starting the final stage you should select a directory to save the resulting file in. To do that click the lower Browse... button:
Specify the directory for saving the result and click Save:
To put the final stroke click the Convert Now! button again to start the actual conversion in multi-pass mode:
Have patience and wait for the process to finish up. The converted video can be found in the destination folder, run it with a media player and compare its quality to that of the same video encoded in single-pass mode.
