User Manual

 Timeline frame rate: Determines the primary frame rate used by the project. A variety
of standard and high frame rate (HFR) settings are available. If you’re importing an
AAFor XML file, this setting is automatically set via an option in the Project Import
dialog. Ideally, you should choose a frame rate before importing media into the Media
Pool. However, the first time you import media into an empty Media Pool, you’re
prompted if the incoming media frame rate doesn’t match the Timeline frame rate set
here, and you have the option of automatically updating this setting to match that of the
media you’re importing. Once one or more files have been added to the Media Pool,
this setting cannot be changed.
 Use drop frame timecode: Enables or disables drop frame timecode for the current
project. Off by default.
 Playback frame rate: Usually mirrors the frame rate selected in the “Video format”
setting (in the Video Monitoring section below), which is typically based on the frame
rate of the external display that’s connected to your video interface, given the “Timeline
Frame Rate” setting. For example, a 50Hz monitor requires a 25 fps playback frame
rate for synchronous display without dropped frames. If you want to monitor playback at
a slower frame rate, type the frame rate of your choice in this field and DaVinci Resolve
will make the appropriate calculations to drop or repeat frames as necessary to
match it. This can be useful for temporarily seeing how clips look in slow motion.
 Enable video field processing: Interlaced media is supported throughout
DaVinci Resolve. The “Enable video field processing” checkbox forces DaVinci Resolve
to process all operations internally using separated fields, in order to properly maintain
the field integrity of interlaced clips in your program. In addition, each clip in the Media
Pool has a Field Dominance drop-down menu in the Video panel of the Clip Attributes
window that lets you specify whether clips are upper- or lower-field dominant; an Auto
setting makes this choice by default.
There is also a corresponding checkbox in the Render Settings panel of the Deliver
page, named “Field rendering,” that lets you enable and disable field rendering when
you’re rendering file-based output.
There are two instances where you want to leave this setting turned off:
–
If you’re working with progressive-frame media, it is not necessary to turn this
checkbox on. Doing so will unnecessarily increase processing time.
–
If you’re using interlaced clips in a progressive-frame project and you’re intending
to deinterlace those clips using the Enable Deinterlacing checkbox in the
ClipAttributes window, then you must keep “Enable video field processing” off.
Otherwise, the Enable Deinterlacing checkbox will be disabled for all clips.
For more information about deinterlacing clips, see Chapter 14, “Modifying Clips and
Clip Attributes.”
If you’re working on a project with interlaced media that you intend to keep interlaced,
then whether or not it’s necessary to turn field processing on depends on what types of
corrections you’re applying to your clips. If you’re mastering your program to an
interlaced format, and you’re applying any adjustments that would cause pixels from
one field to move or bleed into adjacent fields, then field processing should be
enabled; effects requiring field processing include filtering operations such as blur,
sharpen, and OpenFX operations, as well as sizing transforms that include pan, tilt,
zoom, rotate, pitch, and yaw.
On the other hand, regardless of whether you’re outputting interlaced or progressive-
frame media, if you’re not filtering or resizing your clips, and you’re only applying
adjustments to color and contrast, it’s not necessary to turn on field processing for
interlaced material, and in fact, leaving it off may somewhat shorten your project’s
rendering time.
