View Full Version : Deinterlacing & frame rate

Hello,

I am using MeGUI to process files from a DVD into a nice .mkv I can watch on my PC. But my problem is about interlacing.

It's a DVD of old TV shows from the 80s, and it is interlaced @ 29.97 FPS which I think is NTSC or whatever.

To create a .avs script for the files, I ran AutoGK to find out how it would de-interlace and the script is this:

Telecide(movie,guide=1,post=2).Decimate(mode=1,threshold=1.97)

I'm not sure what this is exactly, but the result is 29.97 FPS still. Wouldn't it be 24fps after taking away interlacing? I dont' want to waste bitrate on frames I don't need.

Thanks. :)

If you're using MeGUI, you don't need AutoGK at all. Use MeGUI's built-in analysis tool, which is part of the AVS Script Creator. By the way:

Decimate(mode=1) is useful for hybrid clips having mostly video. It allows you to leave the frame rate at video rates (to get smooth video sequences) but also to ameliorate the effect of duplicate frames that are emitted by Telecide() for film sequences (frames that are normally removed with mode=0).
