Module 4: Basic Video Editing Techniques
1. Timeline Basics: Cutting, Trimming, and Rearranging Clips
Overview: The timeline is where most of your editing work happens. Understanding how to cut, trim, and rearrange clips is fundamental to shaping your video.
Key Concepts:
Cutting: Removing parts of a clip that are not needed.
Trimming: Adjusting the start or end points of a clip to refine timing.
Rearranging: Moving clips around the timeline to change the sequence of your video.
Practical Example: Imagine you're editing a short interview. You have 10 minutes of footage but only need a 2-minute highlight. Start by cutting out sections where the interviewee is off-topic. Then, trim the start and end of each remaining clip to ensure they begin and end cleanly. Finally, rearrange the clips to create a logical flow of ideas, ensuring the strongest points are highlighted first.
Tool Tips:
Shortcut for Cutting: In most editing software, the "C" key activates the razor tool, which allows you to cut clips on the timeline.
Trimming Method: You can drag the edges of a clip in the timeline to trim it, or use shortcuts like "Ctrl + [ " and "Ctrl + ]" to trim the in and out points.
Rearranging Clips: Click and drag clips along the timeline to reorder them. Ensure snapping is enabled to make alignment easier.
2. Using the Razor Tool, Slip, and Slide Edits
Overview: Beyond basic cutting, the razor tool, slip, and slide edits allow for more precise adjustments in your timeline, giving you finer control over your edits.
Key Concepts:
Razor Tool: A tool used to cut clips at specific points in the timeline.
Slip Edit: Adjusts the in and out points of a clip without changing its duration or position on the timeline.
Slide Edit: Moves a clip along the timeline while simultaneously adjusting the adjacent clips to fill the gap.
Practical Example: You have a sequence of action shots, and you want to refine the timing. Use the razor tool to cut at precise moments, such as right before and after a punch in a fight scene. Then, perform a slip edit to adjust the exact frames of the punch within the clip, ensuring it aligns perfectly with the soundtrack. If you need to reposition the clip without leaving a gap, use a slide edit to move the clip while automatically adjusting the timing of the surrounding clips.
Tool Tips:
Razor Tool Activation: Typically, press "C" to activate the razor tool. Click on the timeline where you want to make the cut.
Slip Edit: Hold down the shortcut (usually "S") and click-drag the clip in the timeline. The viewer will show two frames: the new in-point and out-point.
Slide Edit: Hold down "Shift + S" (or another shortcut) and click-drag the clip. The adjacent clips will automatically adjust.
3. Working with Audio Tracks: Sync, Split, and Adjust Volume
Overview: Audio is just as crucial as video in creating a compelling edit. Syncing audio, splitting it from video, and adjusting the volume are essential techniques.
Key Concepts:
Syncing Audio: Aligning audio tracks with the corresponding video clips to ensure they are in sync.
Splitting Audio: Detaching the audio from a video clip to edit it separately.
Adjusting Volume: Modifying the audio levels to balance dialogue, music, and sound effects.
Practical Example: You're editing a dialogue scene where the audio is slightly out of sync with the video. First, manually sync the audio by nudging the audio track in the timeline until the dialogue matches the lip movements. If you need to focus on the audio separately, split it from the video. Finally, adjust the volume of the dialogue to ensure it is clearly audible over background noise or music, using keyframes to gradually increase or decrease the volume as needed.
Tool Tips:
Syncing Method: In most software, you can manually drag the audio track or use tools like "Merge Clips" to auto-sync based on a common audio waveform.
Splitting Audio: Right-click on the video clip and choose "Unlink" or "Detach Audio." The audio can now be edited independently.
Volume Adjustment: Use the audio gain control or add keyframes on the audio track to dynamically adjust the volume over time.
