<p class=level_1_indented><IMG border=0 src="WMVCustomProfileNew.png"></p>

<p class=level_1_indented>WMV Profiles have the following options:<BR></p>

 <ul>

 <li>The <b>Description</b> field explains the purpose of the custom profile, so that you know when to use it.&nbsp; 

 <li><b>Windows Media Video 9</b> compressor is suitable for recording full-motion video.&nbsp; The <b>Windows Media 9 Advanced Profile</b> compressor produces smaller files, but may not play back well on older versions of Windows.&nbsp; If the video has to be played on devices that do not support the newer compressors, use <b>Windows Media Video V8</b>.&nbsp; 

 <li>The <b>Frame Rate</b> is the number of times the video image is updated per second.&nbsp; Low frame rates can make fast on-screen motion, seem abrupt.&nbsp; High frame rates can make the video look blurry, if the bit rate is too low.&nbsp; For most screen-capture applications, frame rate between 5 and 10 fps is high enough.&nbsp; If you are recording fast motion or video playback, the quality can be improved by raising the frame-rate value.&nbsp; 

 <li>The <b>Bit Rate</b> is the amount of data used per second to store the video information.&nbsp; This value is directly related to file size - the higher the bit rate, the bigger the file.&nbsp; It is very important to determine the playback quality.&nbsp; Generally, higher frame rates and larger image size (either a large <a href="RecordingCustomRegion.aspx">region</a>, or high screen resolution) require a higher bit rate to have good video quality.&nbsp; 

 <li>The <b>Key Frame Rate</b> field should be set to a high value.&nbsp; Higher key frame rates can make files easier to edit and to seek in, but may require a higher bit rate to produce good quality video.&nbsp; 

 <li><b>Audio Compressor</b> has two fields.&nbsp; <b>Windows Media Audio Voice 9</b> will produce significantly smaller files, but it is not a good choice for compressing any type of audio, except the human voice.&nbsp; <b>Windows Media Audio 9.2</b> can be selected for the best possible quality, and for recording music.&nbsp; 

 <li>The <b>Audio Formats</b> are listed from lowest to highest quality.&nbsp; Generally, when the <b>Voice</b> compressor is being used, the recorded voice will be understandable at the audio format of 5 Kbps.&nbsp; It can sound better at 12 kbps.&nbsp; When recording is done using the <b>Windows Media Audio 9.2</b> compressor, you must set the audio format to at least 24 kbps.&nbsp; To record music, set to minimum 48 kbps.&nbsp; </li></ul><BR>
