a camera is connected, Adobe OnLocation continually writes the last few
seconds of video to a buffer. By default, the application buffers
five seconds of incoming content to RAM. When you start recording,
Adobe OnLocation adds the buffered content to the beginning of the
clip, ensuring that you capture action that occurs while recording
begins. </p>

<li><p>In the Pre-Roll Buffer section, deselect Enable if you want
clips to begin precisely when you start recording. Or, select this
option to include a buffer, and then specify the number of seconds. </p>

<div class="section"><h4 class="sectiontitle">Set drive space thresholds</h4><p>During recording, digital video files
can grow very large, occupying a large percentage of available drive
space. If drive space becomes low, your system may behave unpredictably. </p>
<p>In
the Field Monitor, Adobe OnLocation warns you about low drive space
in the red message area above the audio waveform. When drive space
becomes dangerously low, the application stops recording.</p>
