three frame sequence
post #1906895 post #3386317 post #2187347 post #2841420
A sequence that consists of three event / action states, otherwise known as frames. This is the minimum number of states a complete sequence (beginning, middle, end) can have. Sequences with two states will either fall under before_and_after, be part of a multipage sequence, or comic page.
In most situations, this concept will also qualify as three_frame_image.
What counts as a frame?
This concept is still being developed, and the definition is subject to updates.
- Any image that advances the progression of some event over time.
- The image before, or after a transition section (collection of frames that show actions happening contiguously). The event frame before a sequence starts can be recognized as a setup frame. Multiple setup frames may be present. Whether or not a setup, or after frame should count depends on how important they are to keeping the sequence complete. The completed result of a transformation sequence is still part of the sequence even though it may take up a larger part of the image than the other parts of the sequence.
- Support frames, which are less important details that highlight smaller changes in a sequence count as separate frames in most cases. These frames can be ignored on a case to case basis on the grounds that they contribute no value to the progression of the sequence.
Simultaneous events should be considered as a single event frame if possible to determine from the image.
Editor's notes
Support frames are largely treated as independent event frames when determining frame counts. Some images make it difficult to determine whether a frame should be part of the sequence, or ignored, but only certain images have this problem. Most images with support frames have a clear focus on a certain aspect from start to finish, and the support frames are mostly unimportant for progressing the sequence. There may be a better way to handle support frames such that sequences with similar progression frames are kept together instead of some ending up into higher frame count groups.
