Basic Editing Techniques
Step 1: Creating and Trimming Clips
Drag and Drop: Drag a clip from the Project panel onto the Timeline to create a new track.
Trim Clips:
Select the clip.
Use the razor tool to split the clip at the desired point.
Drag the edges of the clip to shorten or lengthen it.

Step 2: Adding Transitions
Select the clips between which you want to add a transition.
Open the Effects panel.
Drag and drop a transition effect onto the transition bar between the clips.
Adjust the duration and other parameters of the transition in the Effect Controls panel.

Step 3: Using the Razor Tool
Select the razor tool from the toolbar.
Click on the clip at the desired point to split it into two.

Step 4: Using the Ripple and Slip Edit Tools
Ripple Edit: Moves the following clips to fill the gap created by deleting or shortening a clip.
Slip Edit: Adjusts the in and out points of a clip without affecting the surrounding clips.

Lesson 2: Advanced Editing Techniques
Step 1: J-Cut and L-Cut Techniques
J-Cut: The audio of a clip starts before the video appears.
L-Cut: The audio of a clip continues after the video has ended.

Step 2: Working with Multiple Tracks
Create New Tracks: Right-click in the Timeline and select New Track.
Move Clips Between Tracks: Drag and drop clips to different tracks to layer audio or video.

Step 3: Nesting Sequences
Select a portion of your Timeline.
Right-click and choose Nested Sequence.
Edit the nested sequence independently, and then place it back into the main Timeline.

Step 4: Using the Rate Stretch Tool
Select the clip you want to speed up or slow down.
Right-click and choose Speed/Duration.
Adjust the speed or duration of the clip using the Rate Stretch tool.

Lesson 4: Audio Editing
Lesson 1: Audio Basics

Step 1: Understanding Audio Tracks and Channels

Audio Tracks: Each audio track can hold one or more audio clips. You can have multiple audio tracks in a sequence to layer different sound elements.
Audio Channels: Each audio track can have multiple channels (mono, stereo, 5.1, etc.). These channels determine the sound’s spatial positioning.

Step 2: Adjusting Audio Levels and Panning
Select the audio clip in the Timeline.
Open the Audio Mixer: Go to Window > Audio Mixer.
Adjust Levels: Use the fader to control the overall volume of the clip.
Panning: Use the pan knob to position the sound in the stereo field (left, right, or center).

Step 3: Adding Audio Effects
Select the audio clip in the Timeline.
Open the Effects Panel: Go to Window > Effects.
Drag and Drop: Drag an audio effect (e.g., EQ, reverb, delay) onto the audio clip.
Adjust Parameters: Use the Effect Controls panel to fine-tune the effect’s settings.

Lesson 2: Advanced Audio Techniques

Step 1: Using Keyframes to Automate Audio Levels and Effects
Select the audio clip in the Timeline.
Open the Effect Controls panel.
Create Keyframes: Right-click on a parameter (e.g., volume, panning) and choose Insert Keyframe.
Adjust Values: Modify the parameter’s value at different points in the Timeline to create smooth transitions or dynamic changes.

Step 2: Synchronizing Audio and Video
Select the audio clip that needs synchronization.
Use the Ripple Edit Tool: Adjust the clip’s position in the Timeline to align it with the corresponding video.
Use the Slip Edit Tool: Fine-tune the synchronization without affecting the surrounding clips.

Step 3: Removing Background Noise and Other Audio Issues
Select the noisy audio clip.
Apply Noise Reduction: Go to Effects > Audio Effects > Noise Reduction.
Adjust Settings: Use the Noise Reduction effect’s controls to reduce background noise while preserving the desired audio.
Use Equalization (EQ): Target specific frequency ranges to reduce unwanted noise or enhance certain sounds.
