The orientation of the split is determined by a setting on the V1’s Playback Options
page. Side-by-side comparison is best for golf video, while top-to-bottom comparison
is probably best for swimming video. The arrow buttons allow you to select which
video you wish to control with Digital VCR tools such as Step and Slow motion. The
+ button allows you to control both videos simultaneously.
There are several V1 features which become available in Compare Mode. Video
Synchronization and Compare to Live are described in following sections. Read
about the Slide and Overlay features in the Advanced Digital Effects chapter.
Video Synchronization
People perform various athletic motions with different tempos, or speeds. When two
videos are compared and put into slow motion, the V1 has the ability to either “speed
up” or “slow down” either one of the videos in order for them to share the same
apparent tempo.
This feature is engaged with a check box on the V1’s Playback Options page. To find
this window, launch the V1, click Options and then click Playback at the top of the
window.
When Video Synchronization is engaged, it will only be possible to use the + button
to select both videos if each video has its Impact Point set.
When you first use the + button to select both videos, the V1 will move each video to
the most recent key position of the left-hand video. You will then be able to use either
video position slider or the Slow motion buttons to view the two videos in
synchronization.
The accuracy of Video Synchronization depends on the accuracy of the Key position
settings for each motion. Although Video Synchronization will be possible after only
specification of the Impact Point, you’ll probably prefer the results you achieve after
setting the address, “3 o’clock,” top-of-backswing, and follow-through positions as
well.
Compare to Live
When in Compare Mode, you may click the Live button to open live
video on the selected side. It is possible to use the Slide tool on the
live video window.
NOTE: If you wish to overlay a video with live video, you must first exit Compare
Mode, and then use the Overlay feature as described under Advanced Digital Effects.
