Deinterlace

Figure 35. Deinterlace settings

The deinterlace group has four radio buttons.

Auto	Apply inverse telecine deinterlacing to all telecine video. Apply motion
	adaptive deinterlacing to all video that is not telecine. Switch dynamically
	between the two modes as the content changes. Available for NTSC video
	only.
Inverse Telecine	Apply inverse telecine deinterlacing to all telecine video. Perform no
	deinterlacing of video that is not telecine. Available for NTSC video only.
Motion Adaptive	Apply motion adaptive deinterlacing to all video.
Adjust…	Click this button to display the Adaptive Deinterlace window (see Adaptive
	Deinterlace window).
Off	Perform no deinterlacing of any kind.

Deinterlace settings are applied and stored per-device and are applied to all filters and pins associated with a device.

Changes to this control take effect as soon as you click Apply or OK.

When to deinterlace

When in doubt, deinterlace. In some cases bad artifacts will be seen if you do not deinterlace.

∙NTSC (29.97 fps) users: When in doubt, use Motion Adaptive deinterlacing rather than Inverse Telecine. Motion Adaptive deinterlacing is not ideal for all content, but it works at least adequately with all content. Inverse Telecine is ideal for telecine content – it completely removes interlacing artifacts – but for non-telecine content, Inverse Telecine is the same as no deinterlacing at all.

∙NTSC (29.97fps) users: When the content is known to be 100 % telecine, it is best to use Inverse Telecine. Video sharpness will be superior (see Background − telecine and inverse telecine).

∙PAL / SECAM (25 fps) users: When content is known to be 100 % progressive – that is, shot by a film, universal, or progressive camera, it is best to turn off deinterlacing. Video sharpness will be superior.
