When scoring video, you will often reference your song's timeline based on SMPTE time code, which uses hours, minutes, seconds, and frames as a scale, instead of bars, beats, divisions, and ticks. However, the SMPTE time code used in your song depends directly upon the video format you are scoring to. For example, PAL video, the format used in Europe (including Germany, where Logic's designers and programmers reside), plays at 25 frames per second, while the NTSC video format of North America plays at 29.97 frames per second. Consequently, you must synchronize Logic to the correct frame rate before you begin scoring. To do so, visit the Song Settings dialog's Synchronization pane.
Enabling the SMPTE Time Ruler
As you score the song, it helps to have the SMPTE time ruler enabled so you can see the SPL's precise SMPTE position within the video.
