Choosing Resolution Automatically
The “Choose automatically” option of the Resolution setting bears a bit more explanation.
When selected, only source media with a higher resolution than the selected Timeline
resolution will generate downsized optimized media. How much each clip will be downsized
depends on how much larger each clip is than the Timeline resolution. For example, if you’re
working within a 1080 resolution project, then 8K clips will generate quarter-resolution
optimized media, and 4K clips will generate half-resolution optimized media, such that all
optimized media is somewhere around 1080 resolution. All clips that are 1080 and smaller
generate optimized media at the same resolution as the source clips.
In the example of a 4K project, 8K clips will generate half-resolution optimized media, and all
other clips that are 4K and smaller will generate optimized media at the same resolution as the
source clips.

Switching Between Optimized and Original Media
Choosing whether or not you’re using optimized media is easy. Simply choose Playback > Use
Optimized Media if Available to switch your entire project between using optimized media (if it’s
been generated), or the original media. Furthermore, a checkbox in the Render Settings of the
Deliver page lets you choose whether you want to use optimized media to speed up rendering,
or render using the original media only.
NOTE: Optimized media is not included in Media Management operations, nor is it
included as part of Archive operations in the Project Manager.
Rediscovering Lost Optimized Media
It’s difficult, but it is possible to lose track of optimized media you’ve generated in certain rare
circumstances. For example, if you generate optimized media on another workstation, but failed
to save the project, DaVinci Resolve may lose the relationship between the clips in the Media
Pool and the optimized media files you created. In these cases, it’s possible to rediscover the
optimized media so you don’t have to regenerate it.
To rediscover lost optimized media:
Select the clips in the Media Pool for which you know you have optimized media, then
right-click one of the selected clips and choose Rediscover Optimized Media from the
contextual menu.
