Tab Description
• When you view video at 24 fps, you see the exact timing and sequence on the
original film.
• When you view video at 30 fps, the system repeats every fifth frame and
eliminates de-interlacing artifacts
• Only applies to NTSC video
• Not used for PAL and SECAM video.
• If you select PAL or SECAM as the video standard, you disable inverse telecine.
• The inverse-telecine filter looks for frames added during a telecine process and
removes them.
• This eliminates redundant encoding and improves the quality of encoded frames.
