After you load a sequence into the Asset Editor, you can add clips to the timeline to start building your sequence. MediaCentral Cloud UX allows you to complete this task using multiple common editing methods such as insert (splice-in), overwrite, and replace. This section covers the concept of insert editing. For more information on overwrite, see Performing an Overwrite Edit, and for more information on replace, see Performing a Replace Edit.

When you add your first clip to the sequence, you can perform an insert or overwrite edit. As there are no other assets in the sequence, the method that you use for this first edit is somewhat unimportant. However, the way that you perform subsequent edits has a large impact on the look of your sequence.

An insert or splice-in edit allows you to add a clip before an asset, after an asset, or in the middle of an asset. When you complete the edit, the new asset is inserted after the Mark In point. Any assets following this point are pushed to the right. If you are working in a Sequence, only the assets on the enabled tracks are pushed out.

The following illustration shows a before and after example of a splice-in edit on a shotlist where the asset “Blue Castle” is added to the sequence. In this case, the blue position indicator defines the Mark In point. Notice that after the edit is complete, the remaining section of the original asset is pushed to the right — it is not overwritten.

In some cases, you might choose to perform the edit using the Splice-in button in the Sequence Timeline as illustrated above. In other cases, you might find it easier to drag and drop an asset to the Sequence Timeline from the Media Viewer, Browse app, or Search app. If you drag an asset from the Media Viewer (Source mode), the insert respects any Mark In or Out points that you might add to the source asset. If you drag a Production Management asset from the Browse or Search apps, the entire asset is added to the sequence. If you want to drag and drop an Asset Management asset, you must always first load it into the Asset Editor.

When performing a drag and drop edit to a shotlist or a news sequence, a thin guideline is displayed through the video track of the Sequence Timeline. If you drag the clip above the guideline, the tracks are highlighted dark red, indicating an overwrite edit. If you drag the clip below the guideline, the tracks are highlighted dark yellow, indicating an insert edit. If you keep the mouse button pressed, the Sequence Timeline displays where you can insert the asset. Release the mouse button to perform the insert edit, as shown in the following illustrations.

If you load a Sequence and drag an asset to the Sequence Timeline, the insert edit guideline is not displayed. Instead, an outline of the asset appears that shows you the video and audio tracks that will be edited into the sequence. As shown in the following illustration, you can drag the asset above or below the audio / video tracks to alter the tracks that are used for the edit. Alternatively, you can drag the asset on top of the existing tracks.

If you want more precise control over the insert edit, you might consider using the Splice-in button instead of the drag and drop method. If you are editing a Sequence, you can also adjust the enabled tracks or track patching options for additional control. For more information, see Using the Track Selector.

For Production Management sequences, the aspect ratio and the frame rate is determined by the first clip that you add to the sequence. Any additional clips can have a different resolutions but must match the initial frame rate. See Creating a Sequence.

For Asset Management shotlists, the target frame rate is defined when the shotlist is created. By default, you can add clips with a differing frame rate but mixed frame rate editing might be disabled by configuration in MediaCentral Asset Management.
