A quick way to zoom the timeline is by putting the mouse pointer onto the preview images on the right-hand side or the margin area. Hold down the Ctrl-key and scroll the mouse wheel.
You can also zoom the timeline using the two orange sliders to select just the section of the audio or video you want to see in the margin area:
When you move the mouse pointer over the full preview, two orange sliders appear. Move the right and left slider to the desired position.
If you move the cursor inside the audio or video pane, the media controls appear, and you can start, stop and pause the video, skip forward and backwards. You can also start and stop the multimedia file by pressing the space bar.
From left to right:
Stop: Stops the multimedia file and set the play head to the beginning.
Skip to previous mark: Moves backward to the last mark, which could be the end or beginning of a selection or a section, or the beginning of the file.
Skip backward: Seek backward in the multimedia file.
Play / Pause
Skip to previous mark: Moves forward to the next mark, which could be the end or beginning of a selection or a section, or the end of the file.
Skip forward: Seek forward in the multimedia file.
Volume: On or Off
Click the space bar to stop and start an audio or video file.
If a multimedia document is loaded, you find a number of additional options on the View tab of the contextual document ribbon.
Position of the timeline: The timeline can be positioned at the bottom of the screen horizontally, or vertically next to the audio wave form.
Audio waveform: You can show or hide the audio waveform or the video previews in both the margin or the zoom line.
Auto-scroll: If 'auto-scroll margin' is activated the playhead remains in the middle of the screen and everything else moves (preview images, audio wave form, margin). If 'auto-scroll margin' is deactivated, the playhead moves from the top to the bottom of the screen. This is a lot smoother on your eye. But it means the playhead moves outside the visible area if you have zoomed the video. Which option is more useful depends on what you are currently doing.
Use the right and left arrow keys, to move the position of the playhead by 1/1000th increments of the length of the video that is currently displayed in the margin area.
Use the right and left arrow keys + Ctrl, to move the position of the playhead by 1/20th increments of the length of the video that is currently displayed in the margin area.
