Playback and Performance
labels may also be useful.Sequences may contain mixed-resolution clips. Set the sequence setting to the codec value of the majority of the clips in your sequence. For example, if your project contained an edited 40-minute sequence with clips captured at DV50, yet a special-effects company sent you three MOV files at 8-bit uncompressed, it would make the most sense to set your sequence settings to DV50 since the DV50 codec forms the majority. Prior to final output, you will usually need to render those clips whose codec differs from the sequence setting.Final Cut Pro will always attempt to play back, in real time, any codec that does not correspond to the sequence settings. How Final Cut Pro will treat an element that requires rendering depends on the Real-Time Playback settings of your sequence. You can change the Real-Time Playback (often referred to as RT Playback) to access more playback options. However, the performance of the RT Playback is dependent on your system capabilities. A high CPU speed, multiple processors, maximum RAM, and increased Level 2 and Level 3 processor cache all serve to increase RT Playback in the Timeline. In addition, fast hard drives, fast bus speed, and an accelerated graphics card will also assist maximum RT Playback.Scrub High Quality Choosing this option enables video displayed in the Canvas to be shown at full quality when you scrub or park the playhead. Although this can be useful for checking the image quality or colors of a clip, you may want to toggle it on and off. Consider deselecting this option if you are working with CPU-intensive video codecs such as HD.
These options allow for increased RT playback. Toggle among the RT playback options to find settings that will work best with your project.
