User Manual

 Video Frame Rate: In cases where a clip’s frame rate was specified incorrectly by
another application or recording device, or if there is no frame rate metadata available
at all, you can change what DaVinci Resolve considers the frame rate of the source clip
to be by either using this menu to choose a frame rate from 1 to 120 fps, or choosing
Custom and entering a value from 1 to 32,000 fps (to accommodate high-speed and
specialty format video). Changing a clip’s Video Frame Rate will change its duration and
relative playback speed in DaVinci Resolve. A clip’s audio, however, will be unaffected.
Please note, just because extremely high frame rate media is supported, do not
expect real time performance at excessively high frame rates, and understand that
what performance your workstation is capable of depends on its configuration and the
speed of your storage.
 Data Levels: In certain circumstances, you may find that you need to manually choose
appropriate data levels for clips that are not being interpreted correctly, choosing
between Auto, Video, and Full. For more information on this setting, and how it affects
the image data in your project, see Chapter 7, “Data Levels, Color Management,
and ACES.”
 Pixel Aspect Ratio: In projects using a mix of media with different frame sizes, you can
assign specific pixel aspect ratios using this drop-down menu.
 Horizontal and Vertical Image Flip: Modifies the horizontal and vertical image flip
camera metadata for r3d clips, which is useful for stereoscopic 3D projects shot with a
mirrored camera rig that reverses the media from one eye, or in cases where steadicam
rigs result in upside-down clips. These settings are different from the Flip Image
controls in the Sizing palette of the Color page.
 Image Orientation: For media that has an orientation setting, this lets you change the
rotation of that media so that it’s correctly oriented. Four settings let you adjust by 0º,
90º right, 180º, and 90º left.
 Input Sizing Preset: You can use this panel to assign a Sizing palette preset to select
clips. For example, if you have a special Input Format Preset for standard definition
PALwidescreen clips that you’ve edited into a high definition project, you can do a sort
in the Media Pool to isolate them, and then select them all and apply this preset.
 Field Dominance: By default, the Auto setting enables DaVinci Resolve to automatically
determine whether a particular clip is Upper- or Lower-field dominant. If this automatic
determination is wrong, you can choose Upper or Lower to manually override this.
 Enable Deinterlacing: (only available in Studio version) This checkbox is only enabled
if “Enable video field processing” is turned off in the Master Settings panel of the
Project Settings. Turning the Enable Deinterlacing checkbox on sets DaVinci Resolve
to deinterlace clips using the Deinterlace quality setting that’s located in the Image
Scaling panel of the Project Settings. Normal is a high-quality deinterlacing method
that is suitable for most clips, while High is a more processor-intensive method that can
sometimes yield better results, depending on the footage.
 Alpha Mode: The options presented here depend on the format of the clip you’ve
selected, since only certain formats (such as ProRes 4444, QuickTime Animation,
OpenEXR, TIFF sequences, and so on) are capable of containing alpha channels.
Ifyou’ve imported clips with embedded alpha channels, this panel lets you enable
or disable their use in DaVinci Resolve (by choosing None), choose the type of alpha
channel (Premultiplied or Straight), or invert the alpha channel. If you select a clip that
doesn’t contain an alpha channel, then most of these options don’t appear.
