What does XviD mean and comparing the quality difference between video encoded in XviD and X264?

What is xvid mpeg-4 divx codec?

Both XviD and x264 are encoders. Xvid is an encoder following MPEG-4 Part 2 video coding 

standard, while x264 encodes video streams into the H.264 format and it follows MPEG-4 Part 

10 coding standard. 

XviD consists of two parts. One is DivX’s encoder, and another is DivX’s decoder under multiple 

platforms. Here, we only discuss the video encoding. 


Let me give you two examples of movies being encoded by XviD and x264:

Batman.V.Superman.Dawn.Of.Justice.EXTENDED.2016.iTALiAN.BDRip.XviD-TRL.avi(2.05GB)

Batman v Superman Dawn Of Justice Extended 2016 1080p BDRip x264 AC3 - KiNGDOM(6.61GB)

Yet the size of uperman Dawn Of Justice Extended 720P version DVD 9 is about  8GB,an original 

blu-ray 1080p movie DVD size  is about more than 25-30GB.


What is video encoding?

Encoding is the process of converting source format data, which is usually RAW format occupying 

large capacity, into small-sized Divx or H.264 format using Xvid or X264 encoder respectively. Or, by 

lowering parameters of encoding in the same format, source format is finally output to one or multiple 

specified encoding files. 

What is the difference between video encoded in XviD and X264?

As for common audience, they only need to pay attention to the following two points:

1. with the same quality, video encoded in x264 comes with smaller size than video encoded in XviD

2. with the same file size, video encoded in x264 ensures better quality than video encoded in XviD

You'll see the quality difference of these two movies screeshots below:

 Batman.V.Superman.Dawn.Of.Justice.EXTENDED.2016.iTALiAN.BDRip.XviD-TRL.avi(2.05GB)
