MPEG-2 Video Encoder Settings


Main Settings



The Main Settings tab allows you to configure the encoder.


Generic area

You can select the settings of the MPEG preset and the Video Format in the corresponding fields. Further down in the Generic area, you can define some additional settings for video input, like Profile, Level, Picture type, Field order, and Aspect ratio. 

If you select Progressive Picture type, you can also set a Pulldown mode to convert the number of frames.


Bitrate Control area 

This section allows you to modify the input video encoding Mode and the type of encoding from the Pass field. The encoding type can be Single pass, Multi-Pass Analyze, and Multi-Pass Encode.

           Depending on the Mode, you have different options for the bitrate speed.

For Constant mode you can set the Bit-rate speed in kb/s from the corresponding field and for Variable mode you can set the minimum Bit-rate and the Maximum rate in the respective fields. Also, you can set the VBV buffer size for the latter two modes. For CQ_adaptive and CQ_strict mode you can enter the number of I, P, and B frames.


GOP structure area

In the GOP structure area you can set the Maximum GOP length and the Maximum B-frames count, Depending on your needs, enter the following values:


 For I-frame set the Max GOP length to [1] and the Max B-frames count to [0].

For PAL set the Max GOP length to [12] and the Max B-frames count to [2].

For NTSC set the Max GOP length to [15] and the Max B-frames count to [3].

 In this field you can also set the Scene change detection mode.


The bottom sections, Input info and Statistics, show the configurations of the input, as well as statistics about the encoding speed, bitrate, and number of encoded frames. If you check the Overall PSNR box, you will be able to see the peak signal-to-noise ratio of your video input as well.


If you click the Restore default button, your settings will be changed back to the default ones.


To save your configuration, click OK.
