Creating Multiclip Sequences

The Make Multiclip Sequence command allows you to create multiple multiclips at the same time. When you capture a lot of media files from a multicamera shoot, it can be time-consuming to create multiclips one at a time using the Make Multiclip command. When you need to make a lot of multiclips at the same time, you can use the Make Multiclip Sequence command to create multiclips based on the starting timecode numbers of your clips.

Consider the following example. Suppose you recorded a soccer game with four camcorders (each starting with the same timecode), and you captured each reel as ten individual media files (each representing a different phase of the event). The total number of clips in your project is 40 (4 reels x 10 media files). Instead of creating each of the ten multiclips individually, you can select all the clips at once and use the Make Multiclip Sequence command. A sequence containing ten multiclips is created and the multiclips are placed in chronological order.

When Should You Use the Make Multiclip Sequence Command?

You may want to use the Make Multiclip Sequence command in the following situations:

  • Whenever you have a large number of clips or subclips that you want to make into multiclips.

  • If you have footage from a professional multicamera production, in which all tapes recorded matching timecode from a master timecode generator.

  • If you have footage in which all the tapes begin with matching timecode, but some camcorders recorded continuously while others stopped and started. As long as events occur on each tape at the same timecode number, you can use the Make Multiclip Sequence command.

    Important: If you shot an event with camcorders that were not recording simultaneous identical timecode, you should use the Make Multiclip command and use In or Out points to visually synchronize each camera angle. For more information, see Creating Individual Multiclips.

About the Make Multiclip Sequence Dialog

The Make Multiclip Sequence dialog works similarly to the Make Multiclip dialog, but there are some important differences.

The Make Multiclip Sequence command always groups clips together into multiclips assuming that your footage has matching timecode, so that the same event is recorded on each tape at the exact same timecode number. However, since some cameras may not be continuously recording during the shoot, and you may not always capture media files with exactly the same start and end timecode numbers from each reel, the Make Multiclip Sequence dialog provides options for grouping clips using a specified range of starting timecode numbers. This range is referred to as the timecode synchronization offset.

Figure. Make Multicllp Sequence dialog showing options.
  • Update button: Click here to update the current multiclip grouping based on the value in the “Starting timecode delta” field. This button only appears when you select Use Starting Timecode from the Timecode Synchronization pop-up menu.
  • Automatically edit new multiclip(s) into a new sequence: If you select this option, a new sequence with settings that match your multiclips is created. The new sequence contains each multiclip in chronological order. This effectively re-creates the entire live event as a sequence of multiclips.
  • Include Angle checkbox: Deselect the checkbox for a clip if you don’t want to include the clip in the multiclip you create.
  • Multiclip grouping area: Your selected clips are displayed as one or more multiclips, sorted and grouped based on the timecode of each clip. By default, if the starting timecode numbers of two or more clips are the same, they are grouped together into a multiclip. If a clip has a unique starting timecode number, it is grouped as its own multiclip.

    Note: You can adjust the timecode synchronization offset to group multiclips differently.

  • Media Alignment column: This column shows how each clip is synchronized within the multiclip.
  • Sync Time column: This column shows the starting timecode number of each clip.

Choosing a Timecode Synchronization Option

The Make Multiclip Sequence dialog has several options, one of which is the type of timecode synchronization you want for the sequence. For example, you have the following two clips:

Name
Timecode
Duration
Overlaps other clip
Overlap duration
Clip A
01:00:00:00 to 02:00:00:00
01:00:00:00
01:30:00:00 to 02:00:00:00
00:30:00:00
Clip B
01:30:00:00 to 02:15:00:00
00:45:00:00
01:30:00:00 to 02:00:00:00
00:30:00:00

In this case, if you set the minimum overlap value to 66% (or any value lower than this), clip B is grouped together with clip A into a single multiclip. This is because 66% of clip B’s timecode numbers overlap clip A’s timecode numbers.

Creating a Multiclip Sequence

Once you have clips prepared, you can group them together into multiclips and automatically create a multiclip sequence.

To create a multiclip sequence
  1. Select multiple clips in the Browser, or select one or more bins of clips.

    Figure. Browser window showing a selected bin.
  2. Choose Modify > Make Multiclip Sequence.

    The Make Multiclip Sequence dialog appears. Clips with the same starting timecode numbers are grouped into multiclips, and clips with unique starting timecode numbers are grouped into separate multiclips.

    Figure. Make Multiclip Sequence dialog showing clips with the same starting timecode grouped together as a multiclip, and those with unique starting timecode numbers grouped into separate multiclips.

    If your clips have different starting timecode numbers, you can adjust the timecode offset to change how clips are grouped into multiclips.

  3. Choose one of the following options from the Timecode Synchronization pop-up menu:

    • Use Starting Timecode

    • Use Overlapping Timecode

  4. Depending on which timecode synchronization option you chose above, do one of the following:

    • Enter a value in the “Starting timecode delta” field, then click Update.

    • Enter a percentage in the “Minimum overlap” field, or drag the slider.

      You can also click the triangles to the left and right of the slider to increment the percentage one whole number at a time.

    The clips are shown in new multiclip groupings based on the options you chose. If the clips are still not grouped as you want, repeat the last step.

  5. Deselect the Include Angle checkbox for any angles you don’t want to include in your multiclips.

  6. Select the “Automatically edit new multiclip(s) into a new a sequence” option to create a sequence containing your new multiclips.

  7. Click OK.

A new sequence is created that contains all of the multiclips in chronological order. The location of the multiclips in the Timeline is based on the starting timecode number of each multiclip.

Figure. Browser window showing multiclips created by using Make Multiclip Sequence and the Timeline showing multiclips placed chronologically into the sequence.

Note: If the combined length of all the multiclips exceeds the maximum allowed sequence length, multiple sequences are created.

Example: Creating Multiclips Using a Starting Timecode Offset

In this example, five camcorders recorded footage with consistently synchronized timecode, but not all camcorders started at exactly the same moment. As a result, the captured media files do not all have the same starting timecode number, even though they show the same visual events occurring at the same timecode numbers. Some clips are offset from each other by 1:00 (1 second) or less, while others are offset by as much as 10:00. The goal is to create three multiclips, each containing five angles.

By adjusting the starting timecode offset value and clicking the Update button, you can precisely control how clips are grouped together into multiclips.

Starting Timecode Offset Is 0:00

When the “Starting timecode delta“ field is set to 0:00, most of the clips are grouped as individual multiclips. Only the few clips that have the exact same starting timecode numbers are grouped together. To group more of the clips into fewer multiclips overall, a larger timecode offset is needed.

Figure. Make Multiclip Sequence dialog showing the Starting Timecode delta field set to 0:00.

Starting Timecode Offset Is 5:00

In this example, clips that have starting timecode numbers within a 5-second range are grouped together. The first multiclip contains five angles, but the other multiclips are not yet grouped properly. A larger timecode offset is required.

Figure. Make Multiclip Sequence dialog showing the Starting Timecode delta field set to five seconds.

Starting Timecode Offset Is 10:00

In this example, clips that have starting timecode numbers within a 10-second range are grouped together. There are now three multiclips, each containing five angles.

Figure. Make Multiclip Sequence dialog showing the "Starting timecode delta" field set to ten seconds.

Example: Creating Multiclips Using the Minimum Overlap Options

In this example, five camcorders recorded footage with consistently synchronized timecode, but not all camcorders started at exactly the same moment. As a result, the captured media files do not all have the same starting timecode number, even though they show the same visual events occurring at the same timecode numbers. Some clips are offset from each other by 1:00 (1 second) or less, while others are offset by as much as 10:00. The goal is to create three multiclips, each containing five angles.

When you adjust the minimum overlap percentage value, the multiclip grouping is automatically updated. When the starting timecode numbers of each group of angles varies significantly, this method is often faster and more intuitive than the Use Starting Timecode option.

Minimum Overlap Is 100%

When the minimum overlap is set to 100%, only clips with exactly matching timecode numbers are grouped together.

Figure. Make Multiclip Sequence dialog showing clips with exactly matching timecode numbers grouped together.

Minimum Overlap Is 38%

In this example, the clips are properly grouped into multiclips when the minimum overlap is set to 38%. Because this value is set quite low, the timecode overlap between clips only needs to be 38% of the duration of the longest clip for the clips to be grouped together into a multiclip. Depending on the timecode of your footage, you’ll need to set a different value to group your clips into multiclips as you intend.

Figure. Make Multiclip Sequence dialog showing clips grouped by a minimum overlap of 38 percent.

Note: With some minimum overlap percentages, the same clip may be grouped into more than one multiclip at a time. In this case, you can either adjust the minimum overlap to correct this, or you can simply deselect the Include Angle checkbox for any clips you do not want to include in a multiclip.
