Trimming clips

Trimming creates a section of a file by setting mark in and mark out points. Afterwards the file can be played either in full length or only the marked section.

Notice

Trimming does not create new files. The set points are only stored internally.

You can trim completed files as well as growing files and linked key and fill files.

Clipbox provides several ways for trimming files. Depending on the selected variant a created section is either only available temporarily (within the clip list of a player) or permanently (reusable via the Media window).

Files can be trimmed either via the File preview window (temporarily or reusable) or via the edit mode of the player (temporarily).

Notice

In the File preview window, only the video content of a file is played. This process is internal and independent of the system's live signal output. Existing audio tracks are muted during playback via the File preview window.

On the other hand, changes made in the player's edit mode are visible in the output signal and thus enable a live material preview.

Temporarily trimming a clip via the File preview window

If you trim a clip via the File preview window, the marked section can be applied to the clip list of a player and played.

Notice

The trimmed section is only temporarily available. It remains until you either change the set mark in and mark out points or remove the clip from the player's clip list.

To trim a clip via the File preview window, proceed as follows:

  1. Add one or more files to the clip list as described in steps 1-3 in Creating and playing a clip list.

  2. In the player clip list, right-click the clip you want to trim and select Open file in preview.

    The selected file is opened in the File preview window.

  3. Select the section to be trimmed by setting mark in and mark out points:

    a. To do this, either click directly on the position to be used in the timeline or use the File preview toolbar functions to select a frame-accurate position for the mark in point.

    b. Click the Set mark in icon File preview icon for mark in point to set the mark in point.

    The selected time is applied to the Mark In time display and highlighted in yellow.

Trimming a clip reusable via the File preview window

Another way of trimming via the File preview window is to create a reusable section.

Notice

The set mark in and out points are saved internally, and the trimmed section is afterwards displayed in the Media window as a subordinate element of the corresponding original file. The trimmed section can be used like an original file and can be viewed, for example, via the File preview window or played via a player.

To trim a file and save a selected section internally for reuse, proceed as follows:

  1. Make sure that the Media and File preview windows are displayed. If not, activate them.
  2. Open the file to be trimmed in the File preview window by either double-clicking it in the Media window or by choosing Right-click > Open file in preview.

    Tip

    To trim linked key and fill files, open the corresponding container.

  3. Select the section to be trimmed by setting mark in and out points as follows:

    a. To select a frame-accurate time for the mark in point, either click directly on the corresponding position in the timeline or use the functions of the File preview toolbar.

    b. To set the mark in point, click the Set mark in icon File preview icon for mark in.

    The timecode for the mark in point is set and displayed in the Mark In field.

You can list all available trimmed areas of a file by clicking on this icon.

Trimming a clip via the edit mode of the player

Notice

To use edit mode, the corresponding toolbar must be enabled. The edit mode toolbar is an optional component of the Clipbox user interface that can be enabled or disabled through the Clipbox system settings. The Clipbox system settings should only be changed by trained personnel.

Via the edit mode you can trim the clip currently loaded by a player.

Notice

The trimmed section is only available temporarily. It stays available until you either change the set mark in and out points or remove the clip from the player's clip list.

To trim a clip using edit mode, proceed as follows:

  1. Add files to the clip list as described in steps 1-3 in Creating and playing a clip list.

  2. Click CUE in the playback control of the clip to be trimmed.
