interlace video frame
enhanced by
Topaz Enhance
This example illustrates how to de-interlace video, also called video line-doubling. Click here to download.
In the example, the video clips “cheer.avi” is a small interlaced NTSC DV clip. The example project file “deinterlace.aep”
gives you an example and starting point of using Topaz Enhance to de-interlace video. You can load the project file in After
Effect 6.5 or above to see how we did it.
When you open the example project, you can see five compositions:
- Composition “Deinterlace-1xFPS”: de-interlaces the footage into progressive video at the same 27.97 FPS.
- Composition “Deinterlace-2xFPS”: de-interlaces the footage into progressive video and double the frame rate to
59.94 FPS. Preview this composition and you will find that it has nice slow motion effect. Notice all the filter setting is
the same as compare to “Deinterlace-1xFPS”. The only difference is the frame rate of the composition is 59.94
instead of 27.97. - Composition “Deinterlace-AE”: de-interlaces the footage using After Effects’ build-in method. Switch between this
composition and one of the above compositions, and you will see why you need Topaz Enhance. - Composition “To PAL–Topaz”: converts the NTSC footage into PAL DV format. We use the same method to de-
interlace the NTSC footage first and then scale it up 120% to fit into PAL format. - Composition “To PAL-AE”: show the result of using AE build-in interlacing to de-interlace and convert it to PAL. You
can switch between this and “To PAL-Topaz” to compare the quality.
Using Topaz Enhance to de-interlace a video is simple. You simply apply the Deinterlace* filter to a footage. The default
parameters can be used in most of the situations. We like to use the Sharpne Edge(RGB) filter to make it sharper after de-
interlacing.
The example of converting NTSC to PAL just means as a simple example. If you need to do any enhancement, such as
reducing noise, don’t do it this way. Always change the frame rate as the last step.
Since the Deinterlace* filter is an inter-frame filter (it has “*” as its suffix!), it has to be the first filter to apply in a composition.
