Convert video files to iPod/PSP/3GP/MP4

STEP 1
Click the 'ADD' button to add files to the process list, and then select a video file from the popup window.

STEP 2
Click the 'Browse' button to select the output directory or you can input the directory directly into the text field.

STEP 3
Click the 'Output Video Format' button to select the output video format.

You can adjust the video bit rate to change the output video quality. You can also adjust the audio bit rate and sample rate to change output audio quality.

The higher the video bit rate is, the smoother the output picture will be and the bigger output size will be. The higher the audio bit rate and sample rate are, the better the audio quality will be and the bigger output file will be. Vice versa, the lower the bit rate is, the worse the quality will be and the smaller output size will be. 

STEP 4
When the settings are ready, please click the 'Convert'
button to start converting.
