Video times and sync

Every code can carry the time in the video where its touch happened. That's what lets you click a code to see it, play codes as clips, and send a .dvw whose codes line up with the video in DataVolley and VolleyStation.

How codes get their times​

With a video open, Courtside notes the video time as you code.

  • Typed codes get the time when you typed each code's first key. On a line with several codes, each gets its own.
  • Buttons (Point, timeout, substitution, rotation) stamp the moment you click.
  • Codes Courtside writes (points, rotations, set ends) take the time of the code that caused them.

The season decides how a rally's later touches are timed, in Settings → Video:

  • Exact (default): each code keeps the time of its own first key. Best when you code from video, pausing as you go.
  • Predictive: the rally's first code keeps its time, and each later touch comes a fixed step after the one before (1.5 seconds unless you change it). Best when you code live and type a little behind the play.

When you modify a code, it keeps its time. Codes you add before or after a code take the time of the code after them.

Sync a match to its video​

Use Sync when the codes and the video don't line up, or when you coded the match live and open the video afterwards.

  1. Open the match video.
  2. Find the match's first serve: play, pause, and step frame by frame to the moment of contact.
  3. Click Sync on the transport bar.

The command bar says, for example, "Synced: the first serve is at 3:12.04."

What happens:

  • Codes that have video times move together, so the first serve lands on this frame.
  • Codes with no video time (coded live with no video open) get one from the time of day they were coded, counted from the first serve's.
  • In Predictive mode, each rally's later touches then follow its first touch by the step.

Sync isn't undone with Undo. If you synced at the wrong frame, find the first serve again and click Sync again.

Jump to a code​

Click a code in the code log and the video jumps to its time. Stepping with Alt+Shift+[ and Alt+Shift+] (⌥⇧[ and ⌥⇧] on a Mac) moves the video too.

In the exported file​

The .dvw gets each code's video time in whole seconds. See Exporting a .dvw.
