Well, first of all, hi to everybody. I'm new to this forum and this is my first thread (and post). I'm also new to the HDV world, and that's exactly how I came upon this site. And I must tell you, it was of great help to make me get into HDV. All the footage, the info (and the discussions too) helped me see a lot of things, and also made me dive and investigate (and read a damn lot). You could say too that I'm new to the filmmaking world, and the video world for that matter, having started cinema school last year. But I've had my share of experience and have a couple of shorts under my arm (although only one of them is "serious". Maybe someday you'll see them, but, camera and technology wise, you'll probably wanna kill me, since they were shot on a JVC with the VHS-C format (economy isn't our friend down here, but the latter ones were shot on a Sony DCR-TRV250 Digital8 camcorder; some improvement from the other JVC at least).
So, didn't want to bother you guys and gals with that, but just thought it would be proper to introduce myself a bit since this is my first thread/post. This is an awesome community, and I really hope I can be of some use, now and in the future (as long as free time is on my side).
Now let's go head to the business (and excuse my language if I don't express myself too well, I don't natively speak English, but I'll do my best).
So, I HAVE been looking for info on the things I'll address, but haven't found real answers to them in particular, and I chose this section for this thread because this issue is mainly about the A1 (which is my final choice right now) and I wanted to get info and opinions of people who actually own the camera, to get first hand info rather than a 3-hour-made review of a guy who got the camera just enough to advertise for Sony. Maybe this will point up some things that will be useful for other newbies like me.
I want to buy the camera, and I am in the saving-money process, but the awful amount of money I'll have to spend means I have to carefully get the best and most precise info on it. I don't really know how it must be for you to raise the money needed to get a camera in this price range, but let me give you an example of how hard it is for me: first, the prices are a bit higher than in the USA ($2,300 for the HC1, $3,400 for the A1E -we use PAL here- and $3,900 for the FX-1 -not to mention the $5,500 for the Z1); second, our currency is under a 3 to 1 devaluation, meaning that for every dollar I have to pay 3 pesos (3.07 actually). Imagine you had to pay $16,500 to get a Z1! That's how hard it is for us (and add to that all the salaries have stayed pretty much the same as when we were 1 to 1, of course). On top of all this, there is no place for me to go and check the camera myself and see if it fits my needs (the prices are from a website that's similar to eBay). So you can picture what a perfect buy I have to make. And I'l probably be stuck with this camera for 5 years (being lucky)!
Hell, I didn't want to make this so long, so now I'll really cut to the chase. I'll be drawing some points and comparisons, and also ask some questions. Here I go:
- The A1 has a CMOS chip that has theoretically more resolution than CCDs (and practically so, as is my opinion from the footage I've seen, but I'll adress this later), it consumes less power and makes the cameras smaller and lighter thanks to the ability to have other circuitry built in it to process that which CCD cameras have to do through separate chips. It also reduces (or does it actually eliminate?) smearing. Now, this CMOS has the same size as the CCDs on the FX-1 and Z1 cameras (1/3 inch sensors, although it's only one CMOS vs. 3 CCDs; still that helps for color and resolution, right?) but it has lower sensitivity to light than CCDs (mostly because of the same extra circuitry built in, including the noise reduction processes -CMOS tend to be grainy). For what I've seen (some opinions, a couple of comparison tests and mostly footage) there isn't that much of a difference (if not 1 stop, 2 stops max), even though it's a bit more noisy caused also by the higher gain. Mind you, I should be shooting in controlled conditions for short (budget) films. But still, when shooting, let's say, in the street, with street lights, are the results that bad in comparison to the FX1 and the Z1? (by the way, I saw Kaku's street biking footage and thought it was great; keep up the good work bro, you're awesome!) Are they???
- The zoom on the FX-1 must be great, with that lever and all. And with the A1 I don't think I'll find myself changing from focus ring to zoom ring, so, how good is the rocker? Does the friction against the plastic of the camera make it less smooth? Does it make you do fast zoom starts and stuff like that? (By the way, how would the LANC socket work to have a better zoom controller, 'cause I have no idea on that one)
- Here I'll quote an article from Showreel (http://www.showreel.org/memberarea/article.php?11), which is the last thing I read about the A1 and sums up some stuff I had in mind. Here it is: "As we hunted through the menus we turned on CineFrame. I knew Alan had been pretty nonplussed with the progressive mode on the Z1, and expected the same disappointment from the A1, but here the single CMOS sensor comes into its own, and in 25p mode we got a significant increase in vertical resolution – this seems a true progressive mode to rival the JVC HD100 and 101."
Is this really so? For what I've read, all that CineFrame does is using a single field, delting the other and filling the rest. But according to this, the CMOS sensor's resolution makes up for that, actually making the image look the same (or almost the same) as if it had the full vertical resolution, but without the interlacing (aw, hell, the quote was self explanatory, but I just want my idea to be clear). So, from your experience, is this an actual fact (always considering CineFrame in native camera resolution, either 25 or 30 fps, not faked 24)? I haven't gotten a hold of any CF25 footage on the A1 so I can't tell. Do the images look THAT good?
- Another Showreel quote: "We also liked the way you can adjust the aperture or vary the autoexposure with the lever on the left side of the camera (after a setting in the menu), but criticized Sony for not giving a total manual control of shutter and exposure or any F-stop numbers."
What's with this? Basically, from the manual and photos I've seen, you should be able to set the shutter at a locked speed (let's say 1/60) and then be able to push the EXPOSURE button and use the lever to change it at any given moment. Also, it shouldn't vary the "autoexposure". It's fully manual, right? so if I suddenly want to set the aperture at F1.8 it will stay there FOREVER, right? This supposed issue kind of creeped me out, 'cause if the A1 isn't absolutely manual I'm gonna have to think of it 13 times now instead of 12. Honestly. Oh, and in this field, how different is the HC1 really (I know the A1 has BlackStretch, zebra... but it's only about special features or what?)
- This probably goes for all the HDV cameras out there without PCM sound, but is the MPEG compressed sound bad? I mean, is there any perceptible difference from PCM sound when it comes to a regular or minimally trained human being? (I read it's 384khz, so it should be the equivalent to PCM, or not?)
- Do the the microphone and the XLR module really make a difference (compared to the FX-1 and HC1's built in mics)? I'm pretty sure the sound is a lot better, but how big is the difference (enough to stop and think about the price?)
- Can any of the cameras record video on Hard Drives like the 160HD4 SYMBIO HD HARD DRIVE RECORDER through their firewire connector (you know, the price)? A firestore unit isn't an option for the high cost (I'd rather get a laptop for that price). Also, can it be recorded uncompressed if directly to HDs?
- Does the FX-1 have that more (not better) options than the A1. The A1 has less buttons and more menus, but does it lack configuration options the FX-1 has? Heard that gain cannot be set up manually, nor limited. Also heard it's not...
-This is an EDIT, and it's a very important thing I forgot, since it will limit (or directly prohibit) the use of any camera: it's about the tapes. For what I've read, the Sony cameras have a sort of problem that makes it easy for the footage you shoot to suffer drop-outs (which implicate the loss of many frames with MPEG2 compression). Now that's with regular MiniDV tapes (even if high quality) that are not Sony's special ones. So I don't know if this is a real problem or just marketing, so maybe you could tell me, have you shot on tapes other than Sony's 63 ones? If so, have you had any trouble? I bring this up too because these tapes are worth $32 (you know, approximately 96 pesos) so the filming of ANYTHING without the risk of getting drop-outs would be just prohibitely (means that it prohibites...). I could never afford that. Specially if I wanna keep RAW footage on the DV tapes. Oh, and I can't even buy that in my town, I have to get it from Buenos Aires and pay an extra 15 pesos for shipment. Some nice 111 pesos...
Well, I think that's all, at least for now. I hadn't written any of this before, so I don't know if that covers all of my doubts. I'll ask later in any case. If any o you can or feels in the mood for answering, I would really appreciate if you could answer to each query individually so every aspect is covered.
Thanks in advance, and I hope I'll be contributing to the site soon!
(By the way, I'm terribly sorry for the length of the post, I'll try to be as sinthetic as possible next time)
