If you are editing 4k footage in Davinci Resolve and are having problems with choppy playback or crashing it’s a good idea to change the playback resolution from 4k down to 1080p (1920x1080). This will drastically improve performance and reduce the chance of Davinci Resolve freezing or crashing.

As 4k content slowly becomes the dominant quality standard for footage on YouTube, and other platforms you may be feeling the pressure to start filming and recording content in 4k. The only problem is that editing 4k footage takes way more system resources to edit and often causes Davinici Resolve to crash or grind to a stop. Editing a video at 1080p on a laptop isn’t a problem but as soon as you switch to 4k 3840x2160 everything falls apart.

Thankfully changing the Timeline Resolution in Davinci Resolve is a quick and easy process and will generally solve most of the other performance issues you are having. However, you should also check out the following guide if your problems continue to persist.
