Hey guys .. have any of you figured this out?

I'm shooting HVX footage at 1080/24pa, importing to FCP (after spending countless hours figuring out why the "import P2" command disappeared in FCP 6.0), and I'm encountering the following 2 issues:

1 - the "remove duplicate frames /advanced pulldown" function doesn't work. This is checked in the preferences box within the import window (where I convert to QT). I have been forced to manually perform the pulldown / removal after ingesting / converting.

2 - Once the MXF files are ingested / converted to QT files - they are 1280 x 1080, as opposed to 1920 x 1080. Is this the actual resolution? I was under the impression that the HVX produced 1920.

Any help would be greatly appreciated.
 
All 1080 HD recording formats prefilter the image before recording. HDCAM, HDV, AVC-HD and PAL DVCPRO-HD all downrez from 1920 to 1440 before recording. In the US it goes from 1920 to 1280, so it's a little more horizontally compressed.

But yes, that's normal. Nobody records 1920x1080 (well, the AVC-HD format has the provision to do so, and I think JVC's little new hard disk consumer camera does it, but no prosumer/professional format does as far as I know.)
 
you wont really miss thoes few pixels anyway. the benefits you gain in easier editing and lower over all compression make it worth the small sacrifice in res.
 
Thanks Barry - good to know on the 1920 front. Any ideas why the pulldown function doesn't work? Kinda buggin me out a bit!

The Log and Transfer works just fine, otherwise. Again, it kinda freaked us out when we were on set yesterday and went to offload .. and no P2 Import in the drop down. We figured it out .. but not after much scrambling and research (btw .. what are all those books and manuals for that come with the software!!! ;))
 
p. 3 in the New Features pdf accessed from the Help menu details "log and transfer" changes.

Whenever I install this big of an upgrade, I always read it first.

...so....can you still output/export 1920x1080? Do you have to uprez the downrez, as it were?
 
Yes, in some respects you "uprez the downrez". You are supposed to export it as 1920x1080 if you want to see it in the proper aspect ratio.
 
Hmmm. Barry is that what in Adobe Onlocation it records as 1280/1090. when you import the AVI'S in yo Avid Media Composer do you need just start your projects in 1080i. and is there any other format that Onlocation can record in.
 
This is something I can't get my head around - why does it even enter (for 720) the 1280x720 to 960x720 conversion and then back again, why not just stay in 960x720 all the way through.

Is it to do with display devices and square pixels and the like?
