This is a useful generator for turning interlaced video into a sequence of fields, or for taking a series of fields and interlacing them back together again. Alternatively, it can be used to speed up video 200% or slow it down 50% in a slightly different way than usual.
Additionally, the 100% mode just plays back the video at normal speed - but why is this useful? Say for instance you're working in a 24fps timeline and want to include some very nice slow footage. To get a good slow footage you shoot at 30p instead of 24p. If you were to put the 30p footage directly onto the FCP timeline, FCP would drop frames to make it run at 24p - not what you wanted. By dropping it in this generator and setting it to 100%, each frame of your 30p footage will be mapped to one frame of 24p, making it run longer, giving the desired effect.
Drag the source video into this image well so that the generator can create frames or interlacing as selected below.
Selects the field dominance of the video.
Slows the video down 50% by splitting out the fields from the video and putting them sequentially on the timeline.
Slows down the video 50% by splitting out the fields and interlacing the field with a blended version of that frame. This creates a slightly smoother result than 50% mode.
Plays each frame.
Speeds the video up 200% by taking alternating fields and interlacing them together into frames.
