Proxy Media vs. Other Playback
Optimizations in DaVinci Resolve
There continue to be other methods of optimizing real time performance in DaVinci Resolve, so it’s
natural that one might wonder how this is different from Optimized media, Timeline Proxy Mode, and
other performance optimization techniques available in DaVinci Resolve. The key aspect of proxy
media that differentiates it is that proxy media is independent, portable, and can be created by
applications outside of DaVinci Resolve, if desired.
Proxy Media vs. Timeline Proxy Mode
One of the oldest performance optimization options, originally named “Proxy Mode” in previous
versions of DaVinci Resolve, has been renamed “Timeline Proxy Mode” in DaVinci Resolve 17 to
differentiate it from Proxy Media. While the new Proxy Media feature creates actual media files on disk,
“Timeline Proxy Mode” simply reduces the resolution of the timeline on-the-fly, allowing for increased
real time playback performance. To be clear, Proxy Media and Timeline Proxy Mode are two entirely
different features, which are wholly independent of one another.
Proxy Media vs. the Render Cache
Proxy Media is designed to create easy-to-edit primary source material on the Timeline, for improved
performance before you start editing. The Render Cache is designed to improve the real time
performance of clips that have enough computationally intensive effects (such as Resolve FX, color
corrections, noise reduction, compound clips, fusion compositions, etc.) to slow playback, even at the
current Timeline resolution. Proxy Media is independent and portable (you can move clips wherever
you want; you just have to relink them afterward), while the Render Cache media is not designed to be
moved or interacted with externally and only works with the project it was made for.
Proxy Media vs. Optimized Media
On the surface, Proxy Media and Optimized Media appear similar in function. Both options are
designed to create lower bandwidth, easier to edit versions of source media. However, Optimized
Media is managed internally by DaVinci Resolve, cannot be exported, and is not user accessible. In
contrast, Proxy Media creates fully portable and independent media that can be easily managed
by the user.
Using Optimized Media, Proxy Media,
and Caching Together
How you use DaVinci Resolve’s various performance-enhancing features together is entirely up to you,
but you should know that they’re not an either/or proposition. For example, you can create optimized
media from the camera raw original clips in your project, then enable Timeline Proxy Mode playback to
enhance the performance of your 4K timeline, and turn on Smart Cache to speed up your work in the
Color page as you add Fusion effects, noise reduction, and Resolve FX or OFX to every clip. All of
these optimization methods work happily and seamlessly together to improve your performance while
keeping the image quality of your project as high as the Optimized, Proxy, and Cache formats you’ve
selected in the Master Settings panel of the Project Settings.
