Hi Aram;
With respect to 1080 vs 720p, there is a slight difference, 1080p has more resolution. BUT if you shoot film style, 24p and turn off the detail enhancement, the difference is really minimized. Shoot a test, compare it for yourself but use good glass (primes) and a good monitor…. it’s your choice, the good news is that the camera shoots both.
Good luck,
Steve

Hi Ray:
As John states, yes it can be done, but it requires skill and tools. One possible exception to this premie is that the HDX900 does not have VariCam’s Film REC Ciengamma mode, so you can’t match the 900 to a VariCam if shooting in Film Rec. Many folks often match the VariCam to the 900…. this works quite well and happens often.
Cheers!

RE:
I’m tending to 1080 and I would go pA (advanced cadence) but the guys doing the online and color timing want standard pull down. I don’t think this is a quality issue and PLEASE correct me if I’m wrong on this.
This is a quote from June 3rd, 2005 so maybe a little outdated, but I can’t make sense of it:
“… A couple of reasons NOT to use 1080 24psf for filmouts –720p is a truly progressive format, while the 1080psf format is actually 2 progressive frames that melded back into a single frame (called Progressive Segmented Frames), and in content with high motion that can result with an “interlaced look” even though the content is progressive. …”
The poster could not have meant the judder frames, could he?Thnx,
Aram

Hi S…
A 16×9 2/3″ CCD is 9.6 x 5.4mm, the “2/3” portion is measured diagonally. Here’s a link to a useful site, it gives film / CCD imager dimensions for most video / film formats.

In a nutshell, no. This is one if the very few “standards” in HD, basically all “24P” is NDF.

To All:
With respect to: “Yes, the 1200A can do Assemble Edits. That’s how I laid off over 40 broadcast HD masters with accurate Timecode. You MUST control it via Firewire to do this, but it can be done and it’s quite easy once you figure out the offset””
It is imperative to understand that the AJ-HD1200 CANNOT perform proper i.e. technically correct insert or proper assemble edits, period! This is a lingering confusion that can cause bad program masters and possible high errors i.e. A/V concealment or breakup at at “edit points”. The 1200 does not have the required flying erase heads to clean out the tape before recording, thus any “forced” edit like functions may not play correctly on other decks… This is the very reason we came out with the 1400 deck, that deck has full editing capability and can perfom both insert and assemble edits.
Editing with the 1200 deck in this fashion is a bit like playing Russian Roulette… Click… “phew, lucky so far…” Click…. “phew, lucky so far…” What happens when you aren’t so lucky, your master tape will clitch and corrupt audio / video upon plyback, this is not good for you, your client, nor the industry.
Sorry rant over!

Greetings to all:
I’m sure my collegaue Jeff Merritt will also chime in on this question (yet again)…. However, please let it be known that there will be no new VariCam announced, or shown, or demoed at the NAB in 2007, period. The current model camera, the AJ-HDC27H is a great camera and was completely updated, improved and redesigned only two years to meet the EU Rohs requirements. That camera continues to sell very well and will not be replaced for quite some time.
There will be some new P-2 basd cameras at the NAB, as well as the amazing AJ-HDX900 (yes, the DVCPRO HD tape based camera) we launched last year, but just to reitterate once again, no new VariCam.
Sorry to rant on, it’s just that this queston is a living in the movie Groundhog Day, it’s like Deja Vu all over again!
Cheers!

Hello Pat:
Yes, the HD-SDI OP from the HDX900 is uncompressed 10 bit 4:2:2 if the camera is “live”. You can thus record to uncompressed devices or a D-5 if required. During tape playback this HD-SDI OP is reduced to that of the tape format ie 8 bit and somewhat sub-sampled and compressed.
Cheers!

Chris:
The HDX900 does single frame recording just like the SDX900, it uses a memeory cache then dumpsl that to tape once full. The VariCam has no cache and thus performs “mini-assemble edits 10 frames at a time,
Cheers!

Vic;
If you play any DV, DVCAM, DVCPRO, or DVCPRO 50 tapes on the AJ-HD150, they will only play out in the same aspect ratio they were shot in, ie shoot 4×3 and ouput 4×3, shoot 16×9 and OP 16×9. There is no means of playng a 16×9 tape and getting a letterbox SD OP.
Sorry,
