Hi,

I have a ntsc dvd I want to convert to pal.
It's 99.48% film and progressive, according to dgindex.

I used this script with CCE:

LoadPlugin("D:\DGDecode.dll")
Mpeg2Source("my film.d2v")
LanczosResize(720,576)
ConvertToYUY2

I configured cce to zigzag, progressive, frame rate 23.976 and without ticking the pulldown box.

Then I used the program DGPulldown to change the resulting mpv file. I used the option: Custom: 23.976 to 25.

The thing I think is weird is that the resulting mpv file and also the pulldowned m2v are both video 100%. I happened to load them in dgindex and it says that they are video. I don't understand it. Is that normal or did I make a mistake and something went wrong?

Thanks in advance.

Everything is fine. The measure DGIndex uses to give video versus film percentage consists of examining the pulldown flags and reporting what percentage of the clip has pure 3:2 pulldown (23.976 -> 29.97). Because you are using a different pulldown pattern (23.976 -> 25) it will be reported as video. The film percentage is intended to guide the user in deciding if force film is appropriate, and force film is for undoing only 3:2 pulldown.

Donald, could you add a text output (maybe located near the video/film percentage) where the current and average framerate of the raw encoded frames gets displayed?

Do you mean in the info dialog?

It's doable. Let me think about the best way to present it and then make a proposal. How long would you want the period for the current metric to cover? Same as for bitrate?

Either set this 'current' metric temporal window to the size of the one of the current bitrate, or make the temporal span of this window optional.
