Sequence
A piece of the timeline that shows its children from one frame for a set length.
A sequence shows its children from a start point for a set length. Inside it, the children see their own frame 0 at the moment it starts. A component then does not need to know where it sits in the video.

</Sequence>In HyperFrames a sequence is a clip. Its times are in seconds, so 1 second in and 2 seconds long match the 30 and 60 frames.
Series plays sequences one after another. Loop repeats its children. Sound inside a sequence starts when the sequence does.
