2. Video Compression will adjust the video codec and quality settings for the video you will
record to your hard drive.
EvolutionTV features a built-in hardware encoding chip with support for several formats:
DVD-Compliant MPEG-2:
DVD-Compliant MPEG-2
Half-size:
DivX Certified Home:
DivX Certified Portable:
MPEG-4:
MPEG-4 (iMovie HD):
This format enables you to record in full size MPEG-2 thus delivering
a video file readable by all DVD players. Full size PAL is 720x576, full
size NTSC is 720x480
This format enables you to record in half-size MPEG-2 thus
delivering a video file readable by all DVD players. The video quality
will obviously be lower than with full size MPEG-2
EvolutionTV is the only Mac video capture device to feature fully
DivX compliant hardware encoding. DivX is similar to MPEG-4 and
delivers great picture quality combined with small file sizes. Many
DVD players have DivX decoding capability, letting you read your
DivX files without any additional conversion.
The video size is 720x576 (PAL) or 720x480 (NTSC)
EvolutionTV lets you create video files compatible with the DivX
Portable profile. The main difference with DivX Home is the screen
size set to 352x288. This option is useful if you wish to capture
content for playback on portable devices (Palm, PocketPC, etc...) or
want to reduce the file size of your videos to the minimum allowed.
EvolutionTV can generate MPEG-4 ISO Compliant files. This means
you can capture video in full quality, while maintaining a very low file
size.
As the MPEG-4 file created by EvolutionTV is ISO compliant, it is
readable by most if not all video players, without any software
extension.
MPEG-4 is the preferred video codec for internet broadcasting.
This option will generate a MPEG-4 file directly readable by
iMovie HD. No lengthy conversion will be required when opening
the file in iMovie HD.
The size for the iMovie HD option is 640x480
