View Full Version : Considering Swicth From SD to HD
Dave Perry January 8th, 2005, 03:42 AM Hi everyone,
I've tried searching the site but have not been able to come up with tanswers I need. Plus I'm suffering from pneumonia right now and have little patience.
The company I work for is considering adding HD to its list of services. My boss has a strong broadcast background and everything he shoots is Beta SP. Since hiring me last Spring he has gotten exposed to DV, which is all that I shoot, and has had me shoot one DV project.
He wants to buy a new camera and we were looking at an XL2, that's the one I'm voting for, and a DSR 500 because of his ENG experience.
Obviously the 2 are very different cameras.
Then he sees the FX1 and he falls in love with it. You know, one of these nicely displayed cameras, well light in a high dollar showroom and those 2 letters gracing the camera body, "HD". He even said the camera looked sexy.
Anyway, we edit on a dual 2 ghz G5 FCP HD setup with 2 gigs of RAM and capture Beta with an AJA IO.
1. I assume if we get any of the cameras listed above we will not use the AJA, correct?
2. What are the frame dimensions of the FX1, 1440x1080?
3. Is widescreen handled the same as in DV, eg> 720x480 anamorphic?
4. Is our G5 setup sufficient for editing HD?
5. What else should we consider in the addition of HD to our services?
Thanks, Dave
John Gaspain January 8th, 2005, 04:57 AM 1. Just use firewire (iee 1394)
2. 1440x1080 ...thats HDV 16:9 widescreen. It also does 720x480 DV witha flip of the switch.
3. The FX1's HDV is native 16:9...not anamorphic. No resolution loss with FX1 for widescreen.
4. I dont know about Mac's...but my Sony Vegas - Athlon 2700+ w/1gb ram and scsi drives is barely enough- I need more! You can use Cineform's conversion to make it much more useable. The .m2t files alone are too much for my PC....I have to use cineform and it works fine.
5. An HDV deck would be good. And a good makup artist is valuable because with HD you see every inperfection in full detail. A steady cam would be valuable because the Fx1 has some motion interlace blur with fast motion objects. Basically if you are shooting sports events...dont use this camera anything else is fine.
Dave Perry January 8th, 2005, 05:25 AM Thanks for the reply John.
The frame size of 1440x1080 is actually an aspect ratio of 4:3 if you do the math. Native 16:9 does not mean non-anamorphic. Anamorphic refers to fitting a 16:9 image (one that has not been chopped off at the top and bottom) inside of a 4:3 frame, then when palyed back it's displayed properly and according to the playback devices setting, whether it be an NLE or DVD palyer. Anamorphic does not mean resolution loss either.
My Optura Xi is native 16:9 but the DV frame size for any DV footage is 720x480.
You have answered my questions though, and thanks.
Steve Crisdale January 8th, 2005, 05:57 AM Dave,
Perhaps you should think of going to HDV more along the lines of "if you don't, then maybe your competion will"...
As for your G5 setup. It should have no problem with the HDV stream from the FX-1 or Z1. The only problem area for Mac at this point in time is the 'total HDV solution'; however, it appears many Mac users are achieving success editing in FCP HD Pro with Lumiere HD. Lumiere HD appears to be analogous to AspectHD/ConnectHD for PC in it's capabilities.
If you're reasonably computer savvy with no fear of a briefly steep learning curve, why avoid something with guaranteed benefits; rather than perceiving only the seeming difficulties.
Greg Boston January 8th, 2005, 06:31 AM Dave,
Another thing you might want to throw at your boss is that by waiting another couple monthe, the Sony Z1 will be out and will offer some higher end features that he will like, coming from his ENG background. By then, Apple will probably have announced the timeline for incorporating HDV into FCP. It's rumored that the new release of Imovie will have this support.
The XL-2 IMHO, would be the optimal choice for SD projects.

Graham Hickling January 8th, 2005, 06:41 AM Regarding pixel counts, have a read of the thread "why 1440x1080".
As I understand it, each of the CCDs is 960*1080, and pixel shift is then used to create an effective resolution of 1440*1080. Each pixel is 1.33 rectangular rather than square, thus producing a native (non-anamorphic) 16:9 final image.
Toke Lahti January 8th, 2005, 09:01 AM "Native" 16:9 means that all resolution of given format is used for picture. In ntsc its 720*480, pal 720*576 and hdv 1440*1080.
Because none of these formats use square pixels in 16:9 they can be called "anamorphic".
Heath McKnight January 8th, 2005, 09:40 AM You'll need a fast Mac, but I'm doing all right with a single processor G5 1.6 ghz. and 1.25 gb of RAM.
I enjoyed working with the FX1, and will continue to do so.

I knew there was one thing about FCP HD that prohibitted it from being truly HD compatible. Can you expand a bit more on that or point me in the right direction?
I'll check out some of the threads on Lumiere HD as well. I know very little about HD, and my boss knows even less.

From what I have read about the situation on Mac, and my own experiences on PC, it's clear that the biggest problem for any NLE on either platform is capturing directly to the timeline from the FX-1 (and HD10 for that matter!!).
The 'current state of play' for capturing/editing, delivering HDV material on Mac is a combination of LumiereHD, FCP HD: and for PC (SP2 must be installed) AspectHD/ConnectHD, Vegas 5/Adobe Premiere Pro 1.5.
There are new software developments occuring at ever increasing rates that enhance the HDV editing capabilities of other video appz, so it's likely that what I've just written will be out-of-date by the time I finish typing!!!
I can say that there have already been a number of HDV based pieces reportedly produced on G5s using FCP HD with LumiereHD; and while I haven't personally seen them yet (apart from screen grabs - but check for Kaku Ito's Mac based stuff from the FX-1 including his component via DecklinkHD clips), I'm sure if they're anything like what I see from my PC based system......they wouldn't disappoint!!!!
Dave Perry January 8th, 2005, 07:55 PM Thanks Steve.
I guess I'm confused about what is the "HD" part of Final Cut Pro HD. From Apple's web site:
"Finally, the beauty of HD with the simplicity of DV. Capture DVCPRO HD over FireWire, edit using camera-native footage and output over FireWire with no generational quality loss. RT Extreme, now for HD, can deliver multiple HD streams, effects, filters and transitions in real-time to an attached Apple Cinema Display."
What codec do the FX1 and Z1 capture in?

HD is the descriptor for video with higher resolutions above those of SD.
The HD part of FCP Pro HD indicates that it is capable of handling files of HD resolution. This doesn't mean you get 'native' HD file support. It does mean that as long as the NLE 'recognises' the codec used to encode the HD file, you can open and edit as per any other DV file.
Because the FX-1 and Z1 capture to tape as MPEG2 transport stream of a type that is unsupported as yet by the OS, you need a transcoding option to make captured files available; and that's where LumiereHD comes in, by capturing to a transcoded HD format that FCP Pro HD can import to the timeline.
Once edited, you can reverse the process to record via LumiereHD back to the cam or HD capable deck in HD m2t.
It's almost identical to the process used for exactly the same purpose on PC with AspectHD/ConnectHD in concert with respectively Premiere Pro 1.5 and Vegas 5.
I wouldn't get too concerned over all the Apple DVCPRO HD codec support etc, etc, etc. That's fine in it's own place, but it doesn't mean that if you got an FX-1 or Z1 you wouldn't be able to do anything on a Mac with the amazing stuff you've shot..... Just as I don't get all shaken up by all the PC talk about Real-Time HDV support making HDV editing a 'realistic proposition'.
I've been managing to edit HDV for over a year now (maybe not in RT), so according to any 'nervous Nelly' I must be lieing because realistic HDV editing is "only possible with this RT hardware/software combination" they've only just seen.....
Do the research, know the pieces you need to gather to complete the puzzle, and I'm sure you'll find that the FX-1 > HDV > Mac 'problem' is about as scary as Casper the friendly ghost.
Barry Green January 9th, 2005, 02:17 AM The HD part of FCP Pro HD indicates that it is capable of handling files of HD resolution. This doesn't mean you get 'native' HD file support.
It does if you shoot on DVCPRO-HD. That's where the "HD" in FCP-HD comes in: you can shoot DVCPRO-HD and transfer it via firewire to FCP-HD, edit in the native codec, finish and master back to DVCPRO-HD tape.
Dylan Pank January 9th, 2005, 05:30 AM Mac based HDV editing's "problem" at the moment is it requires time and additional hard drive space.
You capture to a 3rd party programme (LumiereHD (http://www/.lumeireHD.com)), then demux the captured transport streams, (takes time plus additional disk space). Transcode the programme streams into an offline format (more time, plus more space depending on the offline codec chosen). Import the offline files into FCP (this takes moments).
Edit.
FCP can import HDV programme streams exactly into your timeline matching cuts perfectly (this takes seconds on a fast system), but it cannot playback the m2v programme streams files in realtime, though you can add certain effects and see their effect on a frame by frame basis.
Render out a uncompressed HD file of your edit (more time, more disc space, though you can deleted the original transport streams and the offline files prior to this stage), before finally rendering a mpeg2 transport stream (yet more time plus additional disk space).
These do not necessarily make it a bad system, Disc space is relatively cheap, and the advantage is HDV editing is possible on low powered systems (my ancient 450G4 for example), but it has disadvantages for projects that require a fast turnaround. It would be fine for a long form project where a day or so each end of the edit could be given to demuxing, encoding, etc.
The "HD" of FCP-HD really refers to DVCproHD, which can be handled exactly like DV on a powerful enough G4 or G5 system.
Dave Perry January 9th, 2005, 07:19 AM Thanks Dylan, Barry and Steve,
This is great stuff and begs the question, which cameras use the DVCPRO/HD codec and since I work for a Mac shop, wouldn't it make more sense to use one of them rather than an FX1 or Z1?
The process of using Lumiere HD looks pretty simple and straight forward. I went to their web site and watched the demo videos and I use BitVice for MPEG2 creation for DVDs so the whole demuxing/muxing thing is not an issue for me. But, I can tell you right now it will be for my boss.
Dylan Pank January 9th, 2005, 07:41 AM At the moment the only camera that use the DVCproHD codec is the Panasonic Varicam (http://catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?displayTab=O&storeId=11201&catalogId=13051&itemId=68646&catGroupId=15768&modelNo=AJ-HDC27F&surfModel=AJ-HDC27F), but with no lens it's still ten times the price the Z1, and only has a 960*720p resolution (albeit 60p with variable frame rates). However, reports are that its images look great. Rumours abound Panasonic are preparing a prosumer DVCproHD cam but it must be some time off before it's a reality (2006/7?)
Rhett Allen January 9th, 2005, 01:46 PM I'd be willing to bet that FCP will be ready and able to edit HD"V" by the time Sony is selling the Z1. The reality is, there are only 2 cameras capable of shooting HDV right now and neither of them is classified as "PRO". Apple is working on it and will have it ready very soon. Until then, there are a few work arounds such as Lumiere. As far as FCP goes, as long as you have plenty of fast storage and the appropriate input card or codec, it will edit just about any format.
Dylan Pank January 9th, 2005, 03:32 PM Well, if I were a gambling man, I'd take that bet. I remember how long it took FCP to run in OS X! My guess is they're working hard on a way to make HDV as seemless in FCP as DV and DVCproHD are now, and won't release FCP-HDV until it is. Third Quarter 2005 is my guess.
Barry Green January 10th, 2005, 01:48 AM I don't know their timeline for having it integrated, but I believe that Sony announced that Apple has agreed to incorporate native HDV editing into FCP-HD as well.
Mark Sasahara January 15th, 2005, 12:20 AM If you do buy now, get the DSR-500. Bigger chip, better resolution, DVCAM format. I love my XL2, but MiniDv is an inhernetly noisy format. If I had the bucks, I may have gotten a DSR-500.
The FX1 and Z1 are shite, if you're going to go HD, rent an HDWF900 when you need High Def. HD on a 1/3" inch chip seems silly to me, it defeats the whole purpose of HD. It's like shooting fine grain film on Super8 it still looks like crap, 'cuz it's super8.
Don't always jump so soon. Maybe even put off getting a new camera until after NAB? There's lots of new software and hardware happenings coming soon.

Thing is Mark, no offence but we can carry on playing that game till we reach Imax. "The HDWF900 is a piece of crap: it's large, really noisy, and I've read reports that it's prone to overheating and shutting down. 1080*1440 rez is much lower than 35mm and the latitude sucks. Get an Arriflex and shoot film if you're serious etc etc." I'm joking, the 900 is great for some purposes, but it seems a bit daft to come into an HDV forum and start criticising the format in discussion.
The main problem for many in this forum with using a cam like the 900 (apart from the size, noise, the heat) is that once you move up to HDCAM, it's not just the cost of renting the cam, but also HDCAM capable decks, capture equipment, NLE, etc. Whereas HDV editing can be done on any faily decent newish computer with a firewire card and suitable software.
BTW, tape speed aside, DVCAM and miniDV use EXACTLY the same codec. Try shooting DV SP and DVCAM on a PD150 and you'll see NO difference (bar some extra drop outs in DV SPmode.) It's not MiniDV that's noisy, it's the slightly cheaper cameras.
Mark Sasahara January 16th, 2005, 02:01 PM Oops, my bad, I thought this was HD, not HDV.
Dylan Pank January 17th, 2005, 06:31 AM Fair enough mark, an honest mistake. In general the points still stand. Of course any HDV camera is inferior to something like the 900. I notice you sig line says you're a Director of Photography, in shich case you're probably doing big projects where HD is an alternative to 35mm or super16, or maybe Digibeta whereas most of the people in this forum will be looking at HDV as an alternative to or a step up from miniDV, DVCAM or maybe BetacamSP.
Even if your go to a non-HDV HD forum (though HDV is HD) the advantages HDV offers to certain video and film makers are still relevant.
Heath McKnight January 17th, 2005, 12:26 PM Dylan,
I just spent the weekend working with the F900 in the Caribbean in 87 degree weather in a helicopter in the sun, and we had NONE of the problems you described. Either you had a bad unit or something else.
This board is for HDV, not really HD (like the Varicam, F900, Viper, etc.).
Also, this discussion was moved to our HDV Editing Solutions section because of the talk of editing. Let's try to get back to that. For HDV gear, check out this page here (http://www.dvinfo.net/conf/forumdisplay.php?s=&forumid=62).

Dylan Pank January 17th, 2005, 02:37 PM Heath,
I've no personal experience with the 900. My comments were based on numerous reports of such problems I'd read, though re-reading my original post I can see that it might mislead some to think that these were personal experiences (also I might add my comments were not actually totally serious, they were a slightly ironic response to the previous poster)
Anyway, I edited my original post to hopefully clarify the irony and make it clear that these weren't first hand reports of such problems.
Heath McKnight January 17th, 2005, 03:52 PM It's never a good thing to pass judgment on gear one has never used. I made that mistake a couple of years ago with the JVC 5000 line. WHOO! I was way off! <wink>
heath
Dylan Pank January 17th, 2005, 04:29 PM Well, that was my point, I was attempting a slightly sarcastic comment on another post that passed judgement on a format.
As I said later in the post "the 900 is great for some purposes". In no way was my post an attempt to run down the 900.
Mark Sasahara January 17th, 2005, 09:46 PM I have already apologized for my mistaken belief that this was an HD forum, so I'd appreciate being left out of any further discussion. If you want to slag me, write to me directly:
msasaharaphoto@mindspring.com.
Heath McKnight January 18th, 2005, 07:09 AM Mark,
We aren't slagging you at all; I was pointing out that this started out as a mostly editing discussion. We actually do talk about major HD in the HDV acquisition forum.
