Drag-and-drop editing
Editing in Final Cut Express 4 provides a world-class experience. Based on the industry-leading editing tools in Final Cut Pro 6, it lets you edit in the Timeline or with the innovative Edit Overlay tool. Choose from a comprehensive set of edit options, including insert, overwrite, fit-to-fill, and more. To add clips, simply drag them into the Timeline. And thanks to a highly flexible interface, you can move seamlessly through your projects, focusing your efforts on creativity and productivity.

Open format Timeline
No need to worry about formats, frame rates, or conversions. Final Cut Express 4 provides an open format Timeline that accommodates DV (both NTSC and PAL) and HD footage. It even lets you edit clips from multiple formats in real time simultaneously.

Trimming
Ready for more advanced editing tools? Working in the Timeline or a dedicated Trim window, fine-tune your edits with ripple, roll, slip, slide, extend, and shorten. These pro-level trimming tools, combined with the principles of three-point editing, let you experiment with complex variations and edits. That includes “L cuts,” where the audio and video start at different times.

Mix audio on multiple tracks
Take advantage of the flexible audio tools built into Final Cut Express to mix up to 99 audio tracks using pans, levels, and the three-band equalizer. Set key frames on each audio track to adjust level and pan settings over the length of a clip. Import music from Garage Band and combine it with sound effects and voice over to craft a complete multi track audio mix.

Adjust with audio filters
Further enhance your audio with such included Audio Units filters as Reverb, EQ, Echo, and Delay. The new Soft Normalize and Gain feature analyzes sound clips, automatically raising clips to their maximum level without distortion. You can even adjust audio filters in real time, listening to your work in progress and modifying it as the track plays.

Add a voice over
Creating a documentary? You’ll achieve professional results easily by using the Voice Over tool to record your narration. Final Cut Express 4 lets you create quick scratch tracks or add a voice over track as your video plays. Besides offering a countdown cue, the new Voice Over tool records “before start” and “after stop,” providing handles for your recorded audio.
