Effect

Status: Mandatory Attributes:

EffectID Unique alphanumeric ID e.g. ScrollL2R, GlowRed M
Type Type of effect Fade, Color, Crop, Position M
OffsetStartTC Effect start offset after appearance of event. Not to be specified for Fade. Either OffsetStart/EndTCs or Duration+Anchor+ Inclusive must be provided. Not both e.g 00:00:01:00 O
OffsetEndTC Effect end offset after appearance of event. Not to be specified for Fade. e.g. 00:00:02:00 O
Duration Instead of TC, duration may be specified, assuming start at e.g. 00:00:00:05 O
Anchor Determines if the duration is measured from the start of the event or the end of the event. Start, End O
Inclusive Related to Duration. If True, duration is assumed within the In and Out TC of the event. If False, then duration is before In TC or after Out TC of event based on Anchor.

For example, For an Event [——]

Inclusive is [E—-]

Exclusive is E[——]

True, False. Default=True O
Steps Number of steps for effect. If number of steps is specified then the authoring system will try and achieve that number. However, if the rate is too high then the system may e.g. 3 or -1(auto), Default=-1 (auto) O
replace this value with the maximum possible. A value of -1 indicates best effort in which case the authoring tool must calculate the appropriate number of steps.
