Considerations When Working with Mixed Rate Clips
Playback of Mixed Rate Material with Different Frame Sizes
When your mixed rate sequence includes clips of different frame sizes, consider using the
High-Quality Scaling for Real-Time Decode setting. This setting improves image quality during
playback of mixed-format sequences where material requires resizing. For more information, see
“Video Display Settings” on page 1403.
Playback of Mixed Rate Material Using XDCAM AMA Media
Playback limitations when you work with XDCAM AMA media on an optical disk are
particularly noticeable with mixed rate sequences or with mixed rate clips loaded into the Source
monitor. Consider consolidating the media to a local disk. For more information, see “Using
XDCAM and XDCAM EX and XDCAM SR AMA Plug-Ins” on page 367.
2:3 Film Only available for clips or subclips created in 30 fps projects.
Use for a clip or subclip that contains 2:3 pulldown.
Video material can contain pulldown frames in a number of circumstances,
such as the following:
• The telecine process inserts pulldown frames when it transfers film
footage shot at 24 fps to 30 fps video.
• Some cameras can shoot at 24 fps but record at 30 fps, and insert
pulldown frames to achieve the record frame rate.
• Some HD video decks insert pulldown frames when downconverting
material, for example, from 1080p/24 to NTSC 30i.
Progressive Use for progressive video.
Progressive Strobe Use for a clip or subclip that contains repeated frames, for example, a
traditional strobe motion effect clip, or a clip where the original video was
shot at a reduced frame rate such as 15 fps.
Usually results in a better finished look because blending between frames
reduces stuttering motion.
