robNTSC/PAL?
by on Jun 7, 2003 at 10:23:16 pm

Just saw a show on American Broadcast that used MB. The footage looked great and the show's producers explained using Sony DV cams and the "Looks Suite". And not liking the 24p conversion becuase of the jerky effects. However, I don't know if they shot in pal or ntsc, as the team was overseas.

Is it more likely they used NTSC cams & power convertors even in remote areas (Africa), or shot pal to be converted to NTSC?

Can NTSC look that good with de-interlacing, softening and a healthy look suite dosage?

My guess is that it's most likely they shot in PAL, if only for compatibility with the lighting and flickering issues. Most battery chargers will automatically adjust to different power inputs though, so it's not too much of a hassle to shoot NTSC in PAL territory.

I'm in PAL land myself, but most people on this board seem to prefer to deinterlace NTSC to 30p, instead of doing the field-mush thing to 24p. So yes, NTSC can look great if shot well, de-interlaced and treated with something like Look Suite.

so if they were to shoot in PAL, and they didn't like the 24p flickering issues. Am I right in assuming that the flickering issues raised by MB are caused by pulldown from 23.976 to 29.976 rather than the 29.976 to 23.976 that NTSC users comlain about?

Just interested is all, dont have a problem myself. I work in PAL and doubt I'll ever do any work in NTSC.

For a film look, does a Pal transfer to NTSC in MB look more convincing than original NTSC? What would the benefit be?

Well I always assumed that the problems NTSC users were getting (the glitches) were due to the 30i to 24p conversion. PAL works at 25i, and is much closer to the 24p than NTSC is and should work better. But if these reviewers who didn't like the glitches were shooting in PAL like Barrend thinks, then the problem must be during the pulldown back to 29.976 fps.

The benefits of shooting PAL for transfer to NTSC through MB, as listed in the manual, are that because of it's frame rate, every frame is used, eliminating motion artifacts and that it uses larger images to work with.

Aren't there losses in quality when going from a PAL
image to an NTSC image? Not the frame rate stuff, but because
of the way the image scanning is done, etc?

It seems mechanically redundant to go from 25i to 30i. You end up with 30i by adding to the 25i. Anyone doing this?

I don't want to get too technical, here. Just trying to find the holy grail in the filmlook saga. I'm an American chap trying to find the right camera standard for MB projects to post to DVD.

Thanks guys.

Well hollywood movies which get viewed on NTSC VHS go from 24 to 30 without any problems, why should 25 to 24 to 30 have any? you're not losing anything in the transfer.

The holy grail is to use film. But seriously, it depends on your budget. You can get 24p HD cameras. The deinterlacing MB does works best (I assume cos I aint done it, just that the manual says so) with PAL. But if all you can get is a prosumer NTSC digital camera you may just want to simply deinterlace it with fieldskit from revisionfx.com to avoid the glitches that NTSC users complain about.
