horizontal lines when converting PAL to NTSC

Sep 30, 2011 12:48 AM

I've imported PAL mpeg files into Premiere where they have pronounced "combing" or horizontal lines strongly visible especially during motion when viewing both fields in Premiere Program window and in export, but NOT for same clip in Source window or when viewing the files, before import into Premiere, in Media Player etc.. I've read a number of posts and info on field order, but no changes in the field options dialog box seem to remove them.  I

 

It seems to be a defect introduced in Premiere through my Sequence settings and not simply a field settings problem.  I have not set Sequence settings to match clip settings, but to my intended output settings [clips are PAL and I'm exporting to NTSC]. Apparently Premiere in its conversion is introducing these artifacts.

 

If I set the Sequence settings to match the clip settings it fixes the problem - but then when I move to Encore and build, won't this just reintroduce the problem [in a way I won't see till I try to watch the dvd]?

 

Is it good or bad policy to set Sequence settings to desired output settings [what I've been assuming to now]? Any suggestions on how to avoid creating these "combing" artifacts converting from PAL to NTSC, which seems to be the problem? thanks

    How do I choose the right sequence settings?

    Premiere Pro may not be the best tool for PAL>NTSC conversion.  See the link below.  The process was originally designed to covert 30i NTSC into 24p, but the ability to convert between PAL and NTSC is also there.

    is there anything current on this topic?  in seveal forums, its mentioned that premier is not the best tool for converting pal files to ntsc and links to thrid party companies that supposedly "do a better job" but none are still in existance.  So, does CS6 do a better job of this?   thanks...

    From what I have read, it is better to use a different product

    none are still in existance.

     

    Jeff's tutorial is, and all the tools are free (and probably better than anything you'd pay for anyway).
