Variants

General

Anything goes. Note that filters that may be requesting beyond the end of a [VSNode] length in frames (repeating the last frame) should use [VSRequestPattern::General]) and not any of the other modes.

NoFrameReuse

Will only request an input frame at most once if all output frames are requested exactly one time. This includes filters such as Trim, Reverse, SelectEvery.

StrictSpatial

Only requests frame N to output frame N. The main difference to [VSRequestPattern::NoFrameReuse] is that the requested frame is always fixed and known ahead of time. Filter examples Lut, Expr (conditionally, see [VSRequestPattern::General] note) and similar.
