1. Re: horizontal lines when converting PAL to NTSC
joe bloe premiere Sep 30, 2011 8:02 AM (in response to bravedog)Is it good or bad policy to set Sequence settings to desired output settings [what I've been assuming to now]?
How do I choose the right sequence settings?

2. Re: horizontal lines when converting PAL to NTSC
bravedog Sep 30, 2011 9:35 AM (in response to joe bloe premiere)Thanks for your reply. But my reading of this FAQ is that when using multiple file types, it's best to use the primary file type for the sequence because then there is less conversion in sum within the Premiere project.
The problem of the final conversion to output type still exists as a separate step. Certainly the possibility of artifacts being introduced when outputting an NTSC sequence to PAL still exists.
In my particular case, all used files are of the same PAL type, so there is no question of differential conversion within the Premiere project. The problem being discussed is in the conversion to NTSC; if this isn't done in Premiere it will occur in Encore without me being able to preview quality. So isn't it preferable to set the sequence to NTSC in Premiere? Or are you implying if files look ok in Premiere settings, Encore will deal with conversion better than Premiere would have?

JSS1138 Sep 30, 2011 9:39 AM (in response to bravedog)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.

4. Re: horizontal lines when converting PAL to NTSC
bravedog Sep 30, 2011 8:09 PM (in response to JSS1138)ok, for the benefit of anyone who finds this thread looking to solve similar issues, here's what I've learned.
Premiere introduces or can introduce strong "combing" or horizontal lines in PAL video which is placed in an NTSC sequence. These artifacts are related to field dominance issues, but are genuine artifacts introduced to the file which cannot be solved by changing field order etc. [It's unclear if they would arise with similar strength if the Premiere sequence was left in PAL format, then Encore was left to do the NTSC conversion later - since this is quite possible it seems preferable to create the Premiere sequence in NTSC so it can be previewed for artifacts [must set to view both fields in Premiere program window or may miss artifacts till outputting]].
The problem can be largely solved by converting the PAL files to NTSC using another program better at performing this conversion, before importing into an NTSC sequence in Premiere. Adobe Media Encoder works satifactorily, as does AVS Video Converter, and presumably other programs supposedly including Procoder. Hope this helps

JamminJG Mar 4, 2013 10:53 AM (in response to bravedog)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...

John T Smith Mar 4, 2013 11:02 AM (in response to JamminJG)From what I have read, it is better to use a different product

JSS1138 Mar 4, 2013 5:03 PM (in response to JamminJG)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).
