most NTSC files are incorrectly defined

Since you want to IVTC, you will also need to set 'Overwrite input scan type to' to 'telecine'

I did this, the output file is normally played. I can put force QTGMS and output file is also normally played.
How did you determine that the correct this option? Other programs do not define telecine in this file
