De-interlace video (line doubling)
De-interlace Video
The following demo video compares de-interlacing results between Topaz Enhance and After Effect build-in de-interlacing. The video is slow down to 1/4 of its original speed, which also illustrates the good slow motion effect created by Topaz Enhance.

Many videos, such as those from NTSC/PAL analog tape or DV camera, are interlaced. Here is an example of an interlaced video frame.

After Effects can directly import interlaced footage and use them in composition. However, there are many issues related to using interlaced footage this way. A major one is that output video tends to have only half of the vertical resolution after processing.
Topaz Enhance employs a super-resolution based method that uses nine fields to synthesize high resolution frames. If you compare the following frames carefully, especially the details such as spectators' faces, you can see that Topaz Enhance produces much sharper and detailed progressive video.

In addition, Topaz Enhance can double frame rate, e.g. convert a 30 FPS (Frames Per Second) NTSC to a 60 FPS video. This can be used to create slow motion effect with smooth motion. Doubling the frame rate also enable better conversion between video formats, such as between NTSC(30FPS) and PAL(25FPS), or between NTSC and 24FPS for film-look effect.
