[RESOLVED] HDTV deinterlace result in shorter movie

Post by Guest 2 »

I am not very prone to encode interlaced material but this is the only HD source I own of this movie.

It comes from a HDTV mastered to laserdisk AFAIK.

I tried to give it a try with a simple deinterlace=1 parameter and the output is a shorter movie.

I really don't understand nothing of IVTC and deinterlacing, to my limited knowledge if I deinterlace a video, it should remain of the same lenght.

Can somebody please help me to understand how to feed it to AviSynth with DGIndexNV without losing lenght?

This is a small sample.

Thanks.

It has soft pulldown, you can't deinterlace that. You have to do IVTC. When you set deinterlace=1 the pulldown gets ignored; that's why the movie is shorter.

Try this:

dgsource("abyss.dgi",fieldop=1)
