23.976p
Many 24p productions, especially those that are made only for TV and video distribution, actually have a frame rate of 24 * 29.97 / 30 frame/s, or 23.976frame/s (24/1.001 to be exact). Many use the term "24p" as a shorthand for this frame rate, since "23.976" does not roll off the tongue as easily. This is because the "30frame/s" framerate of NTSC is actually 30/100.1%, also referred to as 29.97frame/s – this framerate is matched when video at 23.976frame/s has a 3:2 pulldown applied. Similarly, 60i is shorthand for 60/100.1% fields per second.
Film productions may be shot at exactly 24.000 frame/s. This can be a source of confusion and technical difficulties if material is treated as normal video, since the slightly differing framerates can be problematic for video and audio sync. However, this is not a problem if the video material is merely treated as a carrier for material which is known by the editing system to be "true" 24frame/s, and audio is recorded separately from moving images, as is normal film practice.
[edit] 24p in high definition disc formats
Both HD DVD and Blu-ray Disc support the 24p frame rate, but technical implementations of this mode are different among the two formats. Blu-ray Disc supports 24p with its native timing, while HD DVD uses 60i timing for 24p (replacing missing frames with "repeat field flags").[5]
Μάλλον αυτό που έγραψα πιο πάνω δεν το πρόσεξες ούτε εσύ.
Φυσικά και το πρόσεξα.. αυτά είναι γνωστά εδώ και πολλά χρόνια.
Αλλά, αυτό που λέω εγώ και τα άλλα παιδιά, είναι ότι τα blu ray που έχουν μέσα ταινίες είναι στην συντριπτική τους πλειοψηφία γυρισμένα σε 23.976 καρέ. Αυτά τα 23.976 καρέ για λόγους απλότητας εμφανίζονται σαν "24p".
Κάνε αυτό που σου είπα με τον MPC-HC και θα το δεις και εσύ.. Απλά πράγματα.
