Figure 78. Audio and video capture with preview
This graph shows an A/V capture-only configuration to which a DV Video Decoder Filter has been
added. The properties page also shown (at left) belongs to the DV Video Decoder and can be
accessed directly from GraphEdit and some other applications. This graph captures the video stream
in YUY2 format. As explained previously, the DVSD native DV format is a compressed format,
whereas YUY2 is not. A YUY2 stream at 720x480 is much larger than the dvsd version, and the YUY2
stream at 360x240 is somewhat larger; you would probably want to use this graph only for 1/4 or
1/8 size capture.
Figure 79. A/V capture-only
This graph shows audio + video capture with the Microsoft Video 1 compressor. The compressor
requires YUY2 as its input format and so the DV Video Decoder precedes it. A compressed graph of
this kind substantially compresses the AVI data, at the expense of CPU time and video quality.
