Stacking Movies

Stacking Instance Movies

Two or more Instance movies can be stacked in various configurations in one movie window. The only limiting factors to how many movies can be stacked are the computer’s processing speed and screen size. Each camera angle in the stack movie can be moved around the stack. The stack configuration can be changed; 1×2, 2×2, 4×1, etc. Any camera angle in the stack can be zoomed but in doing so the other movies in the stack are hidden from view.

  1. Open a Timeline with some coded Instances. Find three similar Instances to view and make 3 separate Instance movies from each one.
  2. Set the playhead on each movie to a point at which all three movies will be in sync. This might be one second prior to a particular motion or play.
  3. With all the sync points set in each instance movie, press COMMAND+Y or choose “Stack Instance Movies” from the Windows menu in the Main Menu bar.
  4. A stacked movie will open up with all three Instances in a 3×1 configuration.
  5. To change the stack movie configuration, press CONTROL+COMMAND and click in the stack movie window. Select 1×3 or 3×1 from the pop up menu.
  6. To move a camera angle location in the configuration, press down COMMAND and click and drag the angle to another location in the window.
  7. To show or hide different angles of the stack, use the clapper icons. By clicking on a clapper icon it will hide the angle. If the clapper has an X through it, then it is already hidden, click on it again to show it.

To make viewing angles in the stack easier and avoiding constant rewinding of the movies, there are some playback features built in.

For an instance movie with chapter markers.

  1. If the movie is playing and it is zoomed, the movie jumps back to the previous chapter marker.
  2. If the movie is stopped and it is zoomed, the movie only changes views and does not jump.

For an instance movie without chapter markers or a timeline movie.

  1. If the movie is playing and it is zoomed, the movie jumps back 10 seconds by default. This time can be adjusted in the movies preference panel.
  2. If the movie is stopped and it is zoomed, the movie only changes views and does not jump.

NOTE: If you wish to use this feature, we recommend using the most powerful computer that is available. When stacking 2 or more HD movies together, plan on using highly spec’d machine. Playing multiple movies simultaneously is very cpu and hard disk use intensive.

Stacking Timeline Movies
Fig 83


  1. Multiple timelines can be stacked to create a single timeline and linked stack movie. After capturing and coding multiple synchronous camera angles of an event, each timeline can be merged into a single stacked timeline.
  2. Stacking timelines merges all the coded instances in the timelines that are being stacked. If the same rows exist in each timeline, the instances and rows will be merged into one in the new timeline.
  3. Stacking timelines requires synchronous video. So, it is important that all captures are continuous through the whole event. Pausing and resuming capture will cause the movies to be out of sync. We recommend starting capture 1-2 minutes prior to the start of the event. It is also a good idea to capture audio.
  4. Audio is a great way to find the synchronization point of a movie. If all cameras are not pointed at the same thing when the event starts, audio can provide solid clues to find a worthy sync point.

Stacking timelines is basically the same process as stacking instance movies.

  1. Close all windows except for the timeline and movie windows that are going to be stacked.
  2. Find the sync point in each timeline and position the playhead on each timeline to that point.
    It is a good idea to move the playhead back a couple of seconds by pressing OPTION+LEFT ARROW on each timeline after setting the sync point. This will give a little extra movie time prior to the first event that might need to be coded.
  3. Choose File > Stack timeline movies.
  4. Name the file and save it. Remember to check what type of package is being created when
    you save. Standalone, reference and compressed are all options. We recommend creating a reference package first, so the results can be checked quickly. Do not delete the original movies until you have saved it as a stand alone package.

When saving standalone packages, check the file size, stacked timelines can create some very large files.

Show / Hide Stacked Movie View Angles

Once you have chosen movies stacked in your preferred configuration, you may choose to hide or show selected views.

The baseline of the stack viewer will contain clapperboard and speaker icons (1 per stack view). Click on an icon to hide it (an X will be superimposed over the icon to indicate that it has been hidden) and click on the “X” of an icon to show that stack view

Stack Switch Hotkeys

Stack Switch Hotkeys can be configured so the zooming can be done by pressing keys on the keyboard.

  1. Access the Preferences for Stack Switch Hotkeys in the Movies panel of the SportsCode Preference. Choose SportsCode > Preferences, then press the Movies Icon In The Toolbar
  2. Tick the Stack Switch hotkeys “Enabled” tick box to turn the feature on, then set the Hotkeys for the switching.

There are 12 possible views available for zooming using Hotkeys.

  • Click in the empty buttons to the right of the Movie numbers. Then press a key on the keyboard to set the Hotkey.

When a stack movie is open and a Stack Switch Hotkey is pressed the view will zoom. To unzoom back to the stack view, press the Hotkey again. This can also be done by clicking on the grid icon in the top of the movie. The movie views are numbered from left to right, top down in the grid.

Changing Stack movie view locations in the grid

Hold down COMMAND while clicking and dragging on the view. Drop the view in the approximate location of the grid to relocate.

Changing Stack movie grid layout.

Hold down CTRL+COMMAND and click on the Stack movie. Choose the grid layout from the popup menu. If using a right click mouse, hold down COMMAND, then right click on the stack movie and choose the grid layout from the popup menu.

Stack movie Playback Preferences.

Refer to the Movie Preference section.

For an Instance movie without Chapter Markers or a Timeline movie.

Note: In the case of an Instance movie, this will be a movie made of a single instance only.

If the movie is playing and it is zoomed in or out, the playhead will jump back by the number of seconds which have been specified in the “Lead time for stack switch in timeline movie” panel If the movie is stopped and it is zoomed in or out, the movie only changes view and the playhead does not jump back 10 seconds.

For an Instance movie with Chapter Markers in a Stacked Movie View.

  •  If the movie is playing and it is selected. It will expand the view (zoom in) if the view is of all the movies in the stack. It will contract the view (zoom out), if the view is of an expanded view in the stack. If the “Jump to start of marker after instance movie stack switch” is ticked, the movie time will jump to the previous chapter marker at that beginning of the chapter for both of the view options described above.
  •  If the movie is stopped and it is selected, (for both an expanded or contracted view), the movie only changes view and does not jump to a chapter marker.

Making a Movie from a Folder of Movies

SportsCode captures in a series of movie segments, each segment contains a number in the file name: 00001, 00002, 00003, etc. This sequential numbering scheme is also used by tapeless video cameras. So, to make generating a single movie from a series of sequentially named movie files easy, the Make movie from a folder of movies can be used.

Place all the movie files in the same folder, the choose File > Make movie from a folder of movies and select the folder. A reference movie will be created with all the segments together in sequence according to the number in their file name. Save the movie as a standalone or convert it to another format. This feature is handy if a movie package has been corrupted or when capture has ended unexpeditely. The movie parts can be quickly put back together to create a continuous movie.
