HDV ---> 720p @ 59.94fps

[racer-x]

If you shoot a lot of sports with your HDV camera like me and want to convert your 1080i to 720p @ 59.94 fps, It's very easy to do with Avisynth. HDV 1080i is made up of 60 fields that measure 1440 x 540. The basic principle is to separate the fields into frames and resize them to 1280 x 720. This gives you 720p.

Here is an example of HDV 1080i to 720p @ 59.94 fps:

(13.8 mb 720p mpg) *Note that it's highly compressed 7mbps, it should be twice as much. I prefer H.264, but few can play it back smoothly.

If anyone is interested, here is the script I used:

Directshowsource("myclip.m2t")
assumetff().Bob(height=720)
lanczosResize(1280,720)
#Sharpen(0.15)
#converttoRGB24()
#This script converts 60i HDV footage to 720p @ 59.94fps.

I'd use LeakKernelBob() instead of SeparateFields(). Even a simple Bob() should work better.

I've already experimented with LeakKernelBob() and plain bob(). Neither works as well in my tests. SeparateFields works best for my source. However, I do use LeakKernelBob() for slow-motion stuff.

*Edit* You're right Jagaboo, it really is better with Plain Bob. I revised the script. Oh well, you learn something new every day.
