When the STREAM begins recording using the Loop Record Mode, it gets the Loop Record Time–30 seconds in
this example–and begins recording a segment of that length. When that segment is complete, it is saved
temporarily, and another segment is started. The drawings show the time line divided into 30 second chunks
which correspond to the recorded segments for this example.
When you a tag command is sent to save a loop, the STREAM saves the entire segment you’re in right now
plus the segment that immediately precedes it and the segment that follows it. This means that if you a tag
command is sent just after something exciting happens, you will capture what happened immediately before
the tag. When using the Loop Record Mode, you don’t need to anticipate what’s going to happen in order to
catch everything. Loop lets you catch things after the fact. Because the Loop Record Mode also saves the
segment immediately following the current segment, if you hit tag near the end of the current clip you will still
get one entire segment following your TAG.
NOTE: Each time you send a tag command, the STREAM saves four separate clips. One clip for the segment
preceding the current segment, one clip for the current segment, one clip for the segment following the
current segment, and an XML file for the tag which created the clips. Each of these is stored as a regular clip
file. Nine clip files result from the example above. Also note that there are no entries in the ‘tags’ directory.
Loop & Forward is a combination of the Loop and Clip methods. When you start recording video is captured,
but none of it is saved until the first time you send a tag command. At that point, the STREAM saves a loop
just as it would in Loop, but from that point forward, all video is saved, as it would be when using Clip.
Once you have sent a Tag command to start saving captured video, sending a Tag command again adds a tag
to the clip, again as it would if you were using clip.
Loop & Forward allows you to record using the Clip method, without starting the clip until the actions start.
You can get everything set up, and get yourself over to the starting line without the need to record fifteen
minutes of waiting time which you’re going to want to edit out later anyway. When the starting gun is about
to sound, send a tag to the camera and real recording starts.
Notice that when you do start to capture video, some of the preceding action is captured just as it is when
using the Loop method. This helps ensure that you capture all the action even if you don’t remember to hit
Tag until right after the start. Just remember to set the Loop Record Time to a large enough interval to make
sure you’re covered.
NOTE: Loop and forward creates two clip files, one for the segment immediately preceding the current
segment and one for the current segment plus all of the remaining video. Two clip files, the XML tag file, and
the two tag clip files result from the example in the Loop & Forward illustration.
