# Deinterlacing

* **QTGMC**

import havsfunc as haf # havsfunc script required
video = haf.QTGMC(video, Preset="Slower", TFF=True) # Double the frames
video = haf.QTGMC(video, Preset="Slower", TFF=True, FPSDivisor=2) # Single rate output

:::info
The most confusing thing about qtgmc is when to use it.

Generally:

* **Interlaced content**: live performances, variety shows. Typical formats: .ts/.tp/.m2ts
* **Progressive content**: fancams, vlive/instagram videos, some variety shows (basically 1080p/720p/480p/..., anything with a p. Typical formats: .mp4/.avi

qtgmc is designed to work with interlaced video. Don't waste your time with fancams, it won't do shit.
