View Full Version : Nat. Geo TV production workflow? Dave Nystul February 18th, 2010, 11:55 PM Can anyone tell me what platform they edit on and what their minimum specs are for broadcast? Any input would really help me out. Dave Gints Klimanis February 19th, 2010, 01:11 PM I've been involved with two NatGeo HD productions in 2006-7. For those shoots, everything was shot in 1080i60, and included some material from Sony Z1Us. The production houses were completely independent (one in Australia and the other in LA), so I wouldn't count on a single editing platform. Although the masters were 1080i, NatGeo appears to broadcast in 720p60 as do the majority of HD cable channels. At least, that's the bitstream that is captured directly from the Firewire output of my cable box. The file image size of the MPEG2 bitstream from the Firewire output is 1280x720. The same capture procedure yields 1080i60 from Discovery channel. Mark Job February 19th, 2010, 02:48 PM Can anyone tell me what platform they edit on and what their minimum specs are for broadcast? Any input would really help me out. Dave.....Hi Dave: The standard approach for US TV Network broadcast is as follows..... 1. Shot in Long GOP 50 Mbit per sec on your Nano or XDR @ 1080i 59.94 output from camera. 2. Post on Avid Media Composer. 3. Master output in 720 p 60 & 1080i 59.94 to Sony HDCAM SR Master tape VTR @ 440 Mb or 880 Mb Sincerely, Mark Job Dan Keaton February 20th, 2010, 03:06 AM Dear Dave, I do not have a definitive statement from National Geographic. I have been trying to get this statement for some time now. I have been working with National Geographic. They have been testing the nanoFlash with the results being positive. The nanoFlash and the Flash XDR have been used for some of their productions. Based on my conversations with my contact, I feel that they perfer 1080 at this time. But, please remember, I do not have a definitive answer from them. My advice is to contact them directly. Bill Ward February 20th, 2010, 01:16 PM A few highlights from the NatGeo Tech Specs PDF: 3.0 High Definition Requirements: 1) National Geographic Channel (NGC) requires a High Definition 1080i at 59.94 fps (preferred) or 720p at 59.94fps version of the program master material. It should be delivered on either a Sony HDCAM SR or Panasonic D-5 video tape in 1080i at 59.94 fps (preferred) or 720p at 59.94fps. Letterboxed 4x3 material will not be acceptable. 2) Original shooting format (source tapes): this production shall be photographed in 16:9 with a 14:9 safe action area in HD. 3) Video and Audio program material shall be produced using industry standard and accepted norms of good practice and workmanship. All content must be shot and edited in the native delivery format. 4) NGC supports the production of television programming in the 720p – 59.94fps, 25 & 50, 1080i – 59.94fps 25 & 50 and 1080p –24fps formats. All Vendor Masters must be frame rate converted to 59.94fps and delivered at 59.94fps. NGC will not accept Vendor Master delivered in any other frame rate other than 59.94fps. Masters must be converted on acceptablebroadcast quality conversion system. Conversion masters will be subjected to NGC’s quality control process and will be rejected if found to contain conversion artifacts or to be of poor quality. NGC does not support productions that are shot on HDV tape formats. 6.0 Editing The editing of video material must be performed on an editing system with a minimum codec of DNXHD 220X MXF 10-bit or ProRes 422 10-bit 4:2:2 or equivalent. Gints Klimanis February 22nd, 2010, 02:36 PM Bill, I Googled for that PDF and searched the NatGeo site to no avail. Would you please post some hints for finding that document? "NGC does not support productions that are shot on HDV tape formats." I can assure that some NatGeo HD shows that are re-run even to as late as two weeks ago include portions of HDV tape material. Both production companies that I worked with in 2006-7 showed up with Sony Z1Us to backup the single Sony XDCAM. At least one show used my submitted material from Z1 and/or FX1. Bill Ward February 23rd, 2010, 12:11 PM Gints: Actually, I think I was quoting from the 2007 Tech Specs sheet for Nat Geo. Here is the 2009 version. Bill Ward February 23rd, 2010, 12:14 PM In the 2009 edition, these camera notes: 16.0 NGC Approved List of HD Primary Shooting Cameras For 1080i Productions: (Minimum of 2 million pixels) Thompson Phantom v12 Red Camera Sony HDW-F900R / F950 Sony F23 Sony HDW790 / 730S Sony PDW700 (1920 x 1080 @ 50 Mb/s) Sony HDC-1500 Panasonic AJ-HPX3000 (shoots 1080 only) Panasonic AJ-HDX900 For 720p Productions: (Minimum of 1 million pixels) Panasonic Varicam AJ -HDC27FP Panasonic Varicam AJ-HDX900 NGC Approved List of HD Secondary Shooting Cameras * Note – Secondary cameras are to be used for tight or confined spaces or situations that pose a hazard to your full sized production camera.

Gints Klimanis February 23rd, 2010, 01:17 PM Thanks for the link to the new PDF, Bill. How do they treat Nanoflash recordings from an EX1/EX3 ? Would a 100 MBits/second recording make the primary camera list? Bill Ward February 23rd, 2010, 01:35 PM That's probably a question best addressed to Thierry, but my understanding is they have been doing some tests with the Nano, and it has been largely positive. It would seem to me that the EX-1/3 at 50mbs from the Nano would be virtually the same at the PDW-700/800...minus the glass improvement. Now, that being said, one of the sticking points is that you have to deliver the raw material, and they won't take drives; so you have to find a way to lay off the EX material to tape or to something like an XDCAmHD disk, so they have the source material you cut from. Now, if you wanted to shoot the entire project on the EX-1...dunno. Steve Phillipps February 23rd, 2010, 02:06 PM Bill, interesting list, with some strange items. Why is the HDX900 approved but the HPX2000 is not? They are basically the same camera one with tape one P2, and in fact the 2000 can use AVC Intra, making it a much better camera than the 900. Also no HPX2700 on the list, much better than the tape Varicam or the HDX900 which are both approved. What's that all about? Steve Alister Chapman February 23rd, 2010, 03:45 PM It is an odd list as they don't say what you can record the HDC1500 with. It's primarily used as a studio camera! Also no HPX3700. Perhaps the list was prepared before some of the cams (2700/3700 etc) could be fully evaluated. I'm sure the HPX3700 would be approved for 1080 and 2700 for 720. Also says you should shoot and edit in the native delivery format which is HDCAM SR or D5, they are contradicting their own guidelines. Steve Phillipps February 23rd, 2010, 04:21 PM So the HPX2700 is only good enough for 720 while the HDX900 is OK for 1080? Weird idea. Steve Bill Ward February 23rd, 2010, 06:55 PM Well, in one of the earlier guidelines, it listed the Sony HDW-750 as a preferred camera for 720p productions, only the 750 shoots neither 720 nor p. I suspect many of the cameras listed in this thread would now be fine. Like Alister, I also wondered exactly what media one would be recording on--in the jungles of Borneo--with a handheld Sony HDC 1500. Alister Chapman February 24th, 2010, 03:31 AM What's so weird about thinking that the 2700, a 720P camera would only get approval for 720P productions? Sure the 2700 can output and record by upscaling to 1080, but it's not really 1080i. If your making a 1080i show, you should be using a true 1080i camera. If not make the show 720P. My guess is the HDX-900 is still allowed for 1080 as it is a leftover from the pre XDCAM HD/HPX3000 and would be used to intercut overcrank with other real 1080 material. I expect there are many existing Nat Geo suppliers that invested in them. Steve Phillipps February 24th, 2010, 01:18 PM Alister, it seems to me that you genuinely feel that the EX1 is a superior camera for high quality 1080 productions than the HPX2700 - is this really your position? Steve Dan Keaton February 24th, 2010, 02:47 PM Dear Friends, Our Flash XDR has been used for National Geographic productions. The nanoFlash has also been tested, and it passed their tests. I know it will be used on an upcoming large project. I am not in a position to elaborate much further, but if one wants to use a specific camera with a nanoFlash, for a National Geographic project, I would just go through regular channels and get their approval. Alister Chapman February 24th, 2010, 03:24 PM Alister, it seems to me that you genuinely feel that the EX1 is a superior camera for high quality 1080 productions than the HPX2700 - is this really your position? Steve Where did I say that? There are many other 1080 cameras, HPX3700, PDW-700, PMW-350, all with full raster imagers producing true 1080 images. We've been over this a million time elsewhere. Dave Nystul February 24th, 2010, 04:08 PM So now that I am 1 week into our documentation project for Nat. Geo. TV, here is my acquisition method. I am shooting with our EX-3/Nanoflash combo. The files I am providing the Wash. DC office are MOV. long GOP@100Mbs. The producer was fine with this combination though she did say that their A camera is a PDW-F800. My experience is with this single project only and should not be considered SOP for the whole organization. Best, Dave Steve Phillipps February 24th, 2010, 04:21 PM Where did I say that? There are many other 1080 cameras, HPX3700, PDW-700, PMW-350, all with full raster imagers producing true 1080 images. We've been over this a million time elsewhere. That's what I mean, you've been hinting at it a million times elsewhere. You said a few posts back "What's so weird about thinking that the 2700, a 720P camera would only get approval for 720P productions". This implies that you don't think it suitable for 1080 productions as it's not good enough, and yet I assume you think the EX cameras (particularly with a Nanoflash) are suitable, implying that the EX cameras are superior for high quality results. I just wanted to know if this assumption was right. Don't take it the wrong way or antagonistic/argumentative, I genuinely just want to know your thoughts - do you feel the EX1/3 will give higher quality results on high end 1080 productions than the HPX2700? Steve Alister Chapman February 25th, 2010, 11:30 AM No, I don't think the HPX2700 (or any other 720P camera) should be used as the primary camera on a 1080 production. It has a 720P front end, it is best suited IMHO to 720P productions or to supplement 1080 cameras for it's overcrank capabilities, but not primary camera. What's the point in producing in 1080 using a 720P front end? If you want to use the HPX2700 make the whole show 720P. For a 1080 production where a small compact camera is a priority or necessity over a full size camera I would use an EX1 with NanoFlash, otherwise I would use another true 1080 camera such as a PDW-700, HPX3700 or PMW-350 with a NanoFlash. It's a case of right tool for the job. Kalunga Lima May 20th, 2010, 01:52 AM I'm curious as to what is the advantage of a PMW-350 with a Nano-flash as opposed to images recorded to it's own SxS cards? Thanks Bruce Rawlings May 20th, 2010, 05:13 AM The Nanoflash will record 50 or 100mbts pictures that meet the requirements of many broadcasters. The BBC are not keen on SxS 35mbts pictures. Kalunga Lima May 20th, 2010, 07:20 AM I'm now wondering what benefits this will confer our PDW-F350. Is the camera section 4:2:2? thanks K Dave Sperling May 20th, 2010, 11:27 AM Yes, the camera sections (and hence direct output to the HD-SDI connector) are 4:2:2 on all the EX series cameras. It's the 35Mb recording system on the SxS cards that's 4:2:0 Kalunga Lima May 20th, 2010, 12:25 PM Thanks Bruce & Dave, We have a PDW-F350 and I was considering up-grading to a 2/3" PMW-350, I'm now wondering how just significant the upgrade will be if one was to compare the output from nanoFlash units on both cameras? Kalunga Dave Sperling May 20th, 2010, 01:10 PM I hope I didn't give the wrong impression from the last post, having just noticed you were talking anbout the PDW-F350. (It also is 4:2:2 internally and via HD-SDI, but obviously records in 4:2:0 on the disc.) The big advantages of the PMW 350 are the 2/3" chip for more selective depth of field (and 2/3" lenses), the chips and recording being 1920x1080 as opposed to 1440x1080, slot for wireless receiver, color VF, HDMI output, and significantly more sensitive chips (better low light performance), plus some other features. Of course what you give up is recording to optical pro-disc, and CCD sensors (which are valuable if shooting around flash photography) With either camera the Nano gives you additional recorded quality, and as someone who shoots green or blue screen on a regular basis, I wouldn't consider doing matte work without recording on the Nano. Glen Vandermolen August 24th, 2010, 10:28 PM late to the party, but... I wonder how Nat Geo feels about the Canon XF line? The BBC sure likes them, giving them full acquisition approval. The Canons have a good codec, and the images from the 1/3" 3MOS 1920x1080 full-rez chips are supposed to be really sharp. And what about the HPX370s? Is AVC-intra 100 with 1/3" CMOS good enough? |
