 Add X frame handles: (When rendering Individual Clips) Lets you specify front and
rear handles to be output in frames. This is particularly useful in round trips, when
the finishing editor might want additional handles with which to roll edit points or add
transitions while fine-tuning the graded edit.
 Tone Mapping: (Available in Single clip mode if Dolby Vision or HDR10+ is enabled
in Project Settings) When set to None, the timeline is output using the current color
management settings. When set to either Dolby Vision or HDR10+, you can choose to
output the timeline at a specific peak nit level, color space, gamma, and Data Level
using either the Dolby Vision or HDR10+ metadata available to guide the tone mapping
operation you’ve selected. This makes it easy to set up multiple jobs to output HDR
outputs at varying levels, as necessary.
 Bypass re-encode when possible: (Single Clip mode only) Turning this checkbox
on makes it possible to do a direct copy of the video essence of video items in the
Timeline, directly from the source media to the file being output, when the selected
Format, Codec, and Type matches the source. This also preserves alpha channel data
for compatible formats.
Bypass re-encode eliminates the need to re-encode video media, preserves quality,
and speeds up the output process dramatically, but it only works for clips in the
Timeline to which no additional effects have been added. Doing any grading, adding a
ResolveFX plug-in, adding any overlapping effects or compositing to clips in the
Timeline, resizing or stabilizing clips or altering the output sizing of the Timeline, and
adding Fusion effects will all necessitate re-encoding the entire clip in order to process
these effects. Transitions will require processing, but only for the duration of each
transition.
There are many situations where this is valuable:
–
Fast output of simple edits: You’ve edited a simple cuts-only promo using footage
cut from a previously rendered program using QuickTime ProResHQ 422 media,
and you’re exporting to the exact same format. You can output all of the media very
quickly using Bypass re-encode when possible.
–
Fast output of previously output timelines with small changes: You need to replace
a few shots in an effects-intensive program that’s already been output. You can
import the media file that was output into a new timeline, replace only the required
shots with new media. DaVinci Resolve will do a direct copy of all previously
rendered media, while re-encoding only the new clips with whatever effects and
grading they contain. This lets you quickly re-output a high-quality master file, while
preventing you from needing to re-render the entire program.
–
Fast output of previously output timelines with new audio mixes: You’ve placed a
previously rendered Video+Audio clip onto a timeline and edited a new audio mix
clip to replace the old audio mix. In this situation, a new Video+Audio file will be
quickly written with the new audio, but the video component of that file won’t be re-
encoded, again resulting in a fast export at the highest quality.
TIP: For a list of which video formats are compatible with Bypass Re-encode on
macOS, Windows, and Linux, as well as which formats are compatible with alpha
channels, see the “Supported Codec List” at the DaVinci Resolve Support page,
