Advanced Settings 

– H.264 

 

Figure 4-6: The Advanced Processing - H.264 window 

 

 

 

Use the manual settings option cautiously. Incompatible combination of parameters that were manually set, may result in a 
video and audio quality degradation. Consult with VITEC Support Team for recommendation on specific settings if you wish 
to optimize the compression and streaming settings for a specific application. 

•

 

Level

 - The encoding level of the HEVC/H.264 codec. Choices are 3.0, 3.1, 3.2, 4.0 

(default), 4.1, 5.0. 

•

 

Picture Coding

 - Determines how picture is compressed. Choices are Auto, Frame Only, 

Field Only, MBAFF and PAFF. 

•

 

Aspect Ratio

 

–

 The proportional relationship between the video width and its height. For 

auto configuration select "Same as Input".   

•

 

VLC Mode 

–

 The Variable Length Coding is a code that maps source symbols to a variable 

number of bits. Variable-length codes can allow sources to be compressed and 
decompressed with zero error (lossless data compression) and still be read back symbol
