Profiles
Profiles are used to apply a group of pre-set variables to a job. An encode can be set to produce a fixed quality, or file size, such as 699 MB (one CD). Some options are excluded from the baseline DivX profiles, to maintain wider hardware compatibility. If you wish to use these more advanced codec features, you will need to select an "unconstrained" profile option. Some more recent hardware chipsets (>2005) do support these features.
- Qpel - Tracks motion changes more precisely sharpening images. Tends to work best on mid range rate bit rates. Low rates are too blocky to gain advantage from the finer intra-scene motion detailing, and high bit rates adequately capture all motion details anyway.
- GMC - Improves compression by describing motion in a collective block
