LIVE CLIPPING CONTROL¶
CLIP2VU has a new live clipping user interface, known as the Live Clipping Control.
This lets you watch and make clips from a live stream without having to use a fixed window of content.
As new Live content becomes available, it is immediately available for clipping.
Finding the content you want to clip is also easier, with an adjustable Timeline Window which you can move around and zoom in on, allowing you to quickly find and focus on the content you are interested in and making clip selection easier.
The Timeline is the representation of the stream’s content as thumbnails and timestamps - like a filmstrip.
It is where you set the player’s current playback position and select the current clip.
What you can see on-screen is a portion of the whole Timeline. This is controlled by the Timeline Window.
How the Timeline behaves depends on what kind of content you are viewing:
- If you are viewing a live stream, by default the Timeline shows up to the last 4 hours of content. The right-end of the timeline is the latest live content, known as the Live Edge. New content is continuously being added, pushing the timeline along in the left direction.
- When viewing a VOD stream or a fixed range of a live stream (see Range Control), the Timeline is static, beginning and ending at the start and end of the VOD or fixed range.
You can move the Timeline forwards and backwards by clicking and dragging the area below the thumbnails where the timecode markers are.
If you have a multi-touch trackpad, you can also pan left or right when your mouse cursor is over the Timeline.
Setting the player position¶
On the Timeline the Playhead is the blue line with an arrow on top. It shows and controls the current playback position of the video player.
You can click and drag the Playhead arrow to seek the player. You can also click on the Timeline to jump to that position. A timecode is displayed when the mouse cursor is over the Playhead.
Making a clip selection¶
To make a new clip selection, click on the Timeline where you want the clip to start, and drag across to where you want it to end.
The Playhead moves along with your selection, so you can see what you are clipping.
The clip selection is represented by the yellow bar on the Timeline and in yellow on the Range Bar.
You can click and drag the left and right sides of the selection to adjust the start and end of the clip.
If you drag towards the left or right edge of the Timeline, the Timeline Window will start scrolling in that direction.
Clip selections can also be made and adjusted using the Time Controls below the Live Clipping control and by Keyboard Shortcuts, by setting the In and Out points to the current playhead position.
The Timeline Window controls what portion of the Timeline you can see on-screen.
It is represented by a selection on the Range Bar, showing you where the window starts and ends in relation to the whole Timeline.
This graphic illustrates how the Timeline Window is represented as a selection on the Range Bar, and how it relates to the visible Timeline
You can change the position and scale of the Timeline Window by moving and resizing the Range Bar selection, or by using your mouse or trackpad when your cursor is over the Timeline (see Mouse and trackpad shortcuts).
- Click on any part of the Range Bar to jump the window to that position.
- Click and drag the middle of the Range Bar selection to move the window.
- Click and drag the left or right side of the Range Bar selection to adjust the scale of the Timeline Window.
- While dragging the left or right side of the Range Bar selection, hold the Shift key to expand or contract the selection, zooming the timeline in/out.
When viewing a live stream, the Timeline is constantly shifting to the left as new live content is pushed in from the right.
In this mode, the Timeline Window can have one of two behaviours:
- If the Timeline Window is set to the very end of the Range Bar (the right side), then the Timeline Window ‘sticks’ to the Live Edge. You see this as the Timeline above moves to the left as new content is pushed in from the right.
- If the Timeline Window is set anywhere else on the Range Bar, then the Timeline Window automatically tracks along the Timeline, moving left with it over time. This shows as the Timeline above appears still, but the Range Bar selection gradually moves left to stick to the same period of time.
The Range Bar represents an overview of the whole Timeline.
It is where you can change the Timeline Window, controlling what portion of the Timeline you can see above.
You can also see where the Playhead and current Clip Selection is in relation to the whole Timeline.
To the left of the Range Bar is the time at which the Timeline starts at.
To the right of the Range Bar one of two things are shown:
- For live streams, it shows LIVE. Clicking this jumps the playhead to the Live Edge and starts playback from there.
- For VOD streams and live streams where a fixed range has been set (see Range Control), it shows the time that the timeline ends at.
When viewing a live stream, you can chose whether to have the Timeline show the last several hours of live content, or a fixed range of content from the stream’s archive (where available).
Click the Range Control icon to bring up the Range Control popup.
The top item uses a live Timeline, where the last several hours of content are available and the Timeline is continuously updated with new content.
The second item uses a fixed Timeline, where you chose a start and end time from the stream’s archive. Click on each section to set the Start Date, Start Time and End Time.
To confirm your selection, click the Set Range button.
To cancel, click on any part of the page outside the popup.
