Loop Recording
Save Tags Applied to a Tagged Clip
The length of all loop clips is equal to twice the value of
Loop Record Time at time the recording was done.
The length of all tag clips are equal to the value of Loop
Record Time at the time Save Tags is run.
Loop clips show action that mostly occurs prior to the
tag, with a variable amount of footage following the
tag.
1
Save Tags creates clips that are aligned so that half of the clip
is prior to the tag and half follows it.
1
The Loop method saves only the loop clips. Other action
that occurs during the recording period is not saved.
The original clip on which Save Tags operates contains all of
the action that occurred during the recording period.
Loop clips can be reviewed on the recorder.
Tag clips made with Save Tags must be uploaded to a
computer before they can be viewed.
2
Recordings made with Loop will usually require less
storage than Clip or Loop & Forward recordings.
3
Using Save Tags on a clip requires storage for both the
original clip plus the tag clips.
Table Notes
:
1
See the diagrams for Loop and for Save Tags, in the preceding sections.
2
Tag clips can be deleted from the SDHC card using the recorder by deleting the tagged clip file on which they
are based.. They are automatically deleted when the tagged clip is deleted.
3
Each time you press tag when using the
Loop
Record Method
, a loop clip equal in length to twice the Loop
Record Time is saved. If you press tag, on the average, more frequently than the length of a saved Loop, you
will store a total footage that is greater than the total running time.
Optimizing video quality
Ultimately video quality is in the eye of the beholder. We can measure and adjust clarity, color accuracy, color
depth, white balance, contrast, and all kinds of other things to make the video you take to look as good as
possible to you and your friends. The POV.HD includes both automatic controls that ensure high quality video
under a wide variety of shooting conditions and manually adjustable settings for tweaking video quality.
One of the most difficult problems with hands-‐free POV video is that the scene you’re filming changes
continuously and since you may be busy hanging on and going as fast as you can, the camera needs to take
care of the second to second details.
The POV.HD has built-‐in dynamic exposure control and white balance logic that constantly adjusts, not just the
exposure, but the white balance, contrast level, and color depth as well. Under almost any outdoor shooting
conditions this results in high quality video.
The POV.HD adds four settings that give you the optional ability to tweak the frame processing logic to create
an optimal match between prevailing conditions and your preferences for the look of the final video. You can
shoot high quality video all day without ever thinking about these settings, but under certain conditions, using
the video adjustment settings can produce even better results. With just a bit of practice even a novice can
learn when and how to make beneficial adjustments. If you’re familiar with the adjustments available on a
DSLR still camera, you will already know about these settings.
Spot Exposure Metering
The dynamic exposure control logic works by analyzing the light level and other other key characteristics
of the image in frames as their captured by the camera head, and then adjusting the exposure level of the
imager in the camera head to compensate for changes in light levels. When you ride from sunlight into
shade, the POV.HD will automatically increase the exposure level to compensate.
