# Caching Frames to Memory for Real-Time Playback

After applying many effects to a shot, you may no longer get real-time playback. To play shots with many effects in real time, you can render and temporarily cache the rendered frames into memory.

You can also navigate through shots with the control surface.

NoteYou can also obtain real-time playback by first rendering the shot from the Render Local menu, or with background rendering, and then using the P view mode to play the shot. See About Rendering in Lustre and Setting the View Mode.

To view shots in real time with memory caching:

1. Go to the frame where you want to start viewing in real time.
2. Specify looped playback of the current shot, the entire Storyboard, or between in and out points by clicking the Play Mode button. See Playing Shots.
3. Enable Cache or press M.

   The application renders the current frame and caches the result in memory. It continues forward through the shot or cut (depending on the state of the Play Mode button), caching each frame to memory.

4. Click the Stop playback control at the frame where you want to stop caching. Otherwise, caching continues to the end of the shot or cut and then looped playback starts.
5. If you stopped caching, press the Play control to start looped real-time playback of the cached frames.
6. Use the playback controls to view the cached frames as needed, keeping the Cache button enabled. The cached frames remain in memory until you disable Cache.
7. When you have finished viewing the cut, disable Cache by clicking it again or press N to disable memory caching.
