File containing the Regions of Interest (ROI) used to encode.

The ROI definition starts with a line specifying the frame identifier, the background quality, and an ROI order (in case of overlapping regions), followed by one or more lines each defining a ROI for this frame and the following frames until the next ROI definition.
frame<index>:[BkgQuality=<quality>, Order=<order>]? <posX>:<posY>, <width>x<height>, <quality> Position and width and height are in pixels and are automatically rounded to the bounding LCU units. <quality> is defined as such:
| Quality | Description |
|---|---|
HIGH_QUALITY
|
Higher quality than the rate-control given value |
MEDIUM_QUALITY
|
Same quality as the rate-control given value |
LOW_QUALITY
|
Lower quality than the rate-control given value |
NO_QUALITY
|
Worse possible quality for region without interest |
STATIC_QUALITY
|
Region with static content (that is, exactly same content as in the reference picture) |
INTRA_QUALITY
|
Region all LCU encoded with Intra prediction mode |
QUALITY_ORDER
|
Use quality of the region having the best quality |
INCOMING_ORDER
|
Use quality of the earliest defined region |
Following is an example:
frame0: BkgQuality=STATIC_QUALITY, Order=QUALITY_ORDER
100:52, 8x4, HIGH_QUALITY
144:86, 5x5, LOW_QUALITY
frame13:
12:8, 7x5, HIGH_QUALITY
14:8, 5x5, STATIC_QUALITY
