Preview FX mode processes all timeline effects to create a preview for the current frame. It is useful for viewing timeline effects (stacked or not) in context. Every time you use the frame advance controls or jog the positioner, the image in the Player is updated with all the processed timeline effects. This allows you to make changes to the vertical edit and immediately see your changes. However, when you play the version or clip, the functionality temporarily returns to Realtime mode (until play is stopped). If you create complex timeline effects and find that unrendered black sources appear in some or all your timeline effects when playing in Realtime mode, switch to Preview FX mode to immediately see the results of your changes on the current frame.
Preview FX mode is also useful if you have many unrendered timeline effects, or transitions that use an unrendered timeline effect as an outgoing or incoming clip. Use this mode while you make changes to complex vertical edits, and return to Realtime mode to view the rendered result.
If you are working in an HD project, you should enable the Proxy-Size Player option before using Preview FX mode for faster display of the image. If you have a complicated vertical edit with many timeline effects, you may notice that the Player slows down when jogging or advancing frames. This is normal. Preview FX mode processes the entire vertical edit for the current frame as you jog, which may take more time as you add more timeline effects. It is recommended to use this mode when changing the timing of a layer, such as slipping or sliding, so that you can immediately see the result for the current frame, and then use Realtime mode to view the processed result.
Realtime mode plays clips and versions in real time, allowing you to view your timeline effects. It is recommended that you do most of your timeline work in Realtime mode. However, if your clip has more than one timeline effect, the Player may drop frames or display black frames during playback. In this case, process the timeline effects to get real-time playback. This is true especially if you have stacked timeline effects on many layers. Also, when playing a version with multiple tracks containing unprocessed timeline effects in Realtime mode, you only see the focus track (with its timeline effects).
