Analog Capture

Analog capture is completely software-based. Video encoding quality depends mostly on your various PC components (CPU, memory, hard disk).

Encoding can take place within the WinDVR software, which lets you select the video source. You can also use the MGI VideoWave 4.0 SE editing software for capturing. However, the only encoding format possible with the software provided is MPEG. PAL, NTSC and Secam sources can be recorded.

UYVY 4:2:2 is the native format for recording. The following capturing formats are available:

As far as encoding in WinDVR, the results obtained with MPEG-2 codec are quite good, despite the strong increase of CPU utilization. It appears that the codec MGEG-2 being used is Intervideo's own product. The codec does not take advantage of all the SSE optimizations found in the latest processors. This is unlike the one in Ligos (Go Motion), which is used in many other applications.

And so, during our encoding tests on Athlon XP 1800+, the results speak for themselves:

Recording quality Processor use in %
MPEG 2 720x576 - 6624
kBits/s Preset Best
Between 90% and 100%
MPEG 2 720x576 - 3933
kBits/s Preset Best
Between 55 % and 65 %
MPEG 2 720x576 -2079
kBits/s Preset Best
Between 30 % and 40 %

It is almost impossible to record in full resolution DVD format with this codec, even on an Athlon XP 1800 +! However, video quality is very decent and your MPEG files can be used with other video editing programs like Ulead Media Studio Pro.
