Power!Video
formerly known as "TrueMotion-S"
Power!Video is a commercial codec based on Duck's TrueMotion. Previously named TrueMotion-S,
it is a spatial-only compressor that works well for 4x and higher CD-ROMs, DVD-ROM, and kiosks.
The status of Power!Video is unclear at this time, as it is no longer offered by Horizons Technology.
Architectures Supported
Pros
- Power!Video works well for 4x and higher CD-ROMs and DVD-ROM disks.
- Especially good at high-motion material, since every frame is a keyframe.
- It also works well for kiosks that play video from hard drives.
Cons
- Status of the product is not clear at this time. Horizons Technology
was recently acquired by Titan Corporation, and there is no longer any mention of Power!Video
on Horizons' web page.
- The QuickTime version is not compatible with QuickTime 3 for Windows
- Since Power!Video doesn't support temporal compression, it often doesn't
produce as good results as Cinepak at 2x and lower CD-ROM speeds.
- Windows codec only supported in 16-bit applications (for
example, MacroMedia Director 4, but not Director 5).
Tips
- When a Power!Video compressed movie is doubled on the screen, every
other horizontal line is replaced with a black line. Some people like this
effect, and it does allow for faster playback. Others find this effect
objectionable.
- Due to some issues surrounding Power!Video's implementation of the
"Options" button, you cannot set the Power!Video specific features
in Media Cleaner. This may limit usability in batch processing.
