4. What's a Variable Frame Rate?
4-4 Native Mode (720/24pN and 720/30pN)
for Special Effects Using only
New Function: Native Mode(720/24pN and 720/30pN)
The use of the P2 card as a recording media has led to the development of a
new function, native mode, for recording images at the frame rate used by the
camera. Since the AJ-HDC27H VariCam uses tape as its recording media, its
recording is based on 60p even when the image acquisition frame rate is varied. For
example, in 24p mode, the AJ-HDC27H records 60 fps by applying 2:3 pulldown.
Therefore, to preview the image effect, the recorded data has to be processed
using a frame rate converter and the effective frames must be extracted.
