60i to 50i to 23.9fps?
okay the majority of my footage is pal 50i
however, I do have a significant amount of NTSC material including interviews.now since most dvd players can read pal dvds is it really necessary to conform to NTSC?
the way I see it I can conform everything to 24 or 23.9 fps
or
just conform the ntsc stuff to 50i and then encode a pal dvdessentially i have two questions
1) how compatiby will a pal dvd be with most dvd players in the US? will this be an issue?2) what sequence setting should I use if conforming to 23.9 or 24p?
should I use DV PAL 24 @ 25 or one of cinema tools presents like “24 from DV NTSC” is there any advantage to using 23.9 over 24p?
Okay I guess the second question is actually two questions.
all my material is DV and I am using fcp 5.1.4 Thanks.

This is a very big issue. While it’s my understanding that many PAL DVD players will work with NTSC, I don’t think it’s backwards compatible, meaning I don’t think NTSC DVD players will playback PAL discs (convert PAL to NTSC). Someone correct me if I’m wrong here.

Dropping footage in a FCP timeline normally doesn’t solve the issue of standards conversions. Take a look at Nattress Standards Converter. That’s a better solution.

thanks russ i am actually aware of difference… between using filters like nattress and allow fcp to do its thing.
I as more concerned with which would be eiser to convert to 24 or 23.9 and how to set up the sequence. I wasn’t planning on rendering. my intention is to either use compressor or nattress or cinema tools.
I believe i will just go with 24 since the nattress filter demo only converts to 24 and not 23.9
as for the dvd issue i think i am going to do some tests.

In NTSC, true 24 frames a second isn’t common, especially in broadcast formats. The majority is 23.98 for compatibility with the 29.97 standard.

I’d recommend, because all European players play both NTSC and PAL and only very few North American players play PAL:
Master for NTSC 24p DVD, ie 23.98fps.
Take the 50i to 24p via deinterlace, then slowdown using the “conform” option in cinema tools from 25p to 23.98fps.
Convert the 60i to 24p (and here I’d use my converter plugin)
and then export your 24p NTSC movie, take to Compressor, tell it to make it MPEG2 for DVD and it will add in the pulldown flags. That resulting DVD should play fine in both NTSC and PAL land.

that should be read as take the 50i to 25p > then use CT to go from 25p to 23.98

what is the advantage of using cinema tools to get from 50i to 24p over using the 25-1 option in the film converter? just wondering
-
Cinema Tools will get you from 25p to 23.98fps with zero quality loss or gain – it’s transparent. All you then need is a de-interlace. This all adds up to make the conversion very fast and very high quality. You do, however, have to put up with that speed change of ~ 4%.

Most DVD players are universal. They are then crippled by software to limit playback of zones and formats. Because commercial DVDs are released first in NTSC, many of us in the PAL world make sure our players are unlocked to play NTSC and ignore zones. A quick search on the net should reveal how to mod your player for this. Often it is holding a combination of keys on the front panel when powering up. Also most modern monitors are capable of auto selecting format by detecting the input format and therefore will play PAL or NTSC.
I have been told that in the US there can be problems playing PAL DVDs on auto switching monitors because of line frequency causing a pulsing or flicker problem. Many DVD players can convert internally, therefore playing a PAL disk out as NTSC.
Without a doubt the best way to deal with this issue is to finish the program in its native codec (PAL DV). This will require converting the NTSC elements to PAL. Take the finished master tape to a facility with a decent converter and make an NTSC digi beta master. Use this to make your DVD.
Is this a commercial DVD you are authoring & distributing or just a view copy?
