Mixed Frame Sizes and Mixed Codecs
Most NLEs can freely mix media using different frame sizes, different codecs, and different
frame rates. DaVinci Resolve deals with these combinations in different ways, depending on
what settings you’ve selected in the Project Settings.
Mixing Frame Sizes: Mixed frame sizes are easily handled. The Set Timeline Resolution
To parameter in the Project Settings panel of the Project Settings dictates the current
resolution of the project. Any clips with a frame size that doesn’t match the project
is resized according to the option selected in the Image Scaling panel of the Project
Settings. You can, of course, always manually readjust the sizing of any clip if you want
to make a specific adjustment. All resizing is done using the optical-quality resizing
algorithms in DaVinci Resolve. For more information, see Chapter 133, “Sizing and
Image Stabilization.
Mixing Codecs: Mixed codecs are also not a problem, as long as the different codecs
used by the media in the project you’re importing are compatible with the list of codecs
and formats that DaVinci Resolve supports. For more information about the currently
supported list of codecs and formats, check the Blackmagic Design support page for
DaVinci Resolve. This list is updated often with newly supported formats.
Mixed Frame Rates
DaVinci Resolve also supports mixed frame rates, although there is a setting you must choose
to ensure the best results for the NLE you’re importing from. By default, mixed clip frame rate
support is enabled via the “Mixed frame rate format” pop-up menu that appears either in the
Master Project Settings, or in the Import AAF or XML dialog.
The different options available in the “Mixed frame rate format” pop-up are available to let you
conform projects using the method of mixed frame rate calculation used by the NLE a project
was originally edited in; different NLEs have different ways of mixing frame rates, and that used
by Final Cut Pro 7 is different from that used by Final Cut Pro X or Avid Media Composer. If you
need to change this setting, you must do so before you import any media into the Media Pool;
once the Media Pool is populated, this setting can no longer be changed.
