and i got an average of >70% type: video (with Honor Pulldown Flags)

but i cant find an entry in the manual, know only ntsc and film

do i have to ivtc it, checking manuallay what exact method is used?

You have to figure out what kind of video you have. I can't tell you. DGIndex is just telling you that 30% of your video has 3:2 pulldown with RFF flags. Is the other 70% straight video that can't be IVTC'ed, or is it hard 3:2 pulldown that can be IVTC'ed? That is the question. Find a non-RFF'ed portion using DGParse and then step through it to see if it looks like video or 3:2.

My guess would be that it is hybrid video/film.

hi neuron2
i couldnt do anything with 'video' at first cause i only know ntsc, pal and film as type thats why i asked

i parsed a part as you said and i always get 3:2 pattern breaks like

full updated parse log here (http://people.freenet.de/fatxy/dgparse.txt)

can you point me to the next steps of what i can / should do now please?

thanks a lot

You are using the old command line version of the parse utility. It won't work on newer D2V file formats. Please use the utility in the DGIndex Tools menu. Post the resulting log here like you did that one.

Looking at the log, you can see that at encoded frame 57, display frame 71, a string of 2's starts. So serve this video into VirtualDub with Honor Pulldown Flags and go to frame 71. Then start stepping forward. Hopefully it is not a static scene. See if you see the typical pulldown pattern of 3 clean frames followed by 2 combed ones. If so, you have hard telecining in that section. If you see all combed frames in motion scenes, then it is video.

Check this for several different runs of 2's or 0's for motion scenes, because those are non-pulldown sections. Report what you find.

Then make a project using Honor Pulldown Flags and then do external IVTC:

AssumeXXX()
telecide()
decimate()

Set field order correctly with AssumeXXX(): TFF or BFF. Try with and without guide=1.

coolio now it looks fine thanks a lot neuron2
using this now:
AssumeTFF()
telecide(guide=1)
decimate()
