DivX Plus HD Profile
DivX has defined profiles which are subsets of MPEG-4/AVI and H264/MKV standards. Because the grouping is a specific subset of what is in the standards, there are certification processes for each of the profiles that device manufacturers must follow. Below is the DivX Plus HD profile.
All DivX Plus HD certified devices bearing a DivX Plus logo will adhere to the profile outlined in the table below, as would any tools that support the DivX profiles. DivX Plus HD devices are also tested for compliance against the DivX HD 1080p profile for MPEG4/AVI certification in order to maintain backwards compatibility

x264 compatibility
According to documentation provided by DivX on their DivX Developer Portal, it is possible to make DivX Plus HD compatible files via other H.264 encoders, such as the open source x264 encoder.{{cite web x264 --vbv-maxrate=20000 --vbv-bufsize=25000 --level 40 --bframes 3 --keyint -o
Despite the popular transcoding tool HandBrake dropping .avi container support, it can still be used to create DivX Plus compatible videos if MKV is selected for format, x264 is selected for video codec, AAC is used for audio codec, and the following options are passed into the advanced settings:{{cite web level=40:ref=2:bframes=2:subq=6:mixed-refs=0:weightb=0:8x8dct=0:trellis=0:vbv-maxrate=20000:vbv-bufsize=25000:weightp=0
