100fps: How to deinterlace Video the right way. Examples, Tricks, Comparisons

When fine lines and details tremble/flimmer/quiver in your videos

 

 

This a capture from an Iraqi TV broadcast. I don't know what it's about (maybe he[?] is trying to sell you university diploma "as seen on Oprah"), but in the background you see a lot fine lines.

Only the new "Deinterlace - Smooth" by Gunnar Thalin is good enough to produce a quiverfree movie. "Smart Bob" by Donald Graft produces also a good result, but other footage is worse.

However, Donald Graft is a talented programmer and a gift to the Virtualdub/Avisynth community. Check out his filters at his site.

Interestingly enough the quiver free version is the smallest. So you not only get the best quality but also the smallest file size.

All files are 520x280 to make them comparable. You have to watch them 4:3.

b) c) d) were double the height originally (and 4c) would even quiver more with double the height).

  

a) Method 4a) "Field bob" (3.3 MB)

b) Method 4b) "Deinterlace Smooth" (1.8 MB) [best quality, smallest size]
Original size (4.2 MB)

c) Method 4c) Avisynth's "Bob" (2.7 MB)

d) Donald Graft's filter "Smart Bob" (2.3 MB)
Original size (5.6 MB)
