3 CCD DV or 1 CCD HDV?
 
I currently have a Canon GL-1 (which I bought in 2001), a mini digital video 3 CCD camcorder. I was wondering if I would get better image quality from my current camera or one of the less expensive HDV cameras that have a single CCD or CMOS (like the JVC GR-HD1 or Sony HVR-A1U).

I use the camera to make art videos and very low budget documentaries.

Thanks in advance for the feedback...

You should get much better image quality from an A1U. You could get better image quality from an HD1 (in good lighting), but it would be a little trickier to shoot with than a GL1.

Leo Pepingco March 22nd, 2006 01:42 AM

If we discount the number of chips, the type of chips and their sizes. Then it comes down to it, HDV offers that much more in resolution alone. Hence a better quality.

Other than the possible problems with image bleed and processing, sometimes having an advanced single chip over some relix 3CCD's is often better. The A1, hands down wins the race agasint almost all the DV 3CCD cams out there for around the same price.

Ken Hodson March 22nd, 2006 04:17 PM

The A1 does have some issues with the rolling shutter. Where users have complained having with motion shots. I believe hand held stuff was the main reason. Run and gun might still be the domain of 3chip SD cams.

this is indeed true. there are *some issues* with the A1 due to where exposure and shutterspeed may be set, just like every other camera out there has some issues with other aspects of shooting.
Very hard to beat the A1 for many things. We recently used 3 A1's for a rodeo shoot capture, and they worked great where no other camera could have possibly gone.

Zack Birlew March 22nd, 2006 05:13 PM

The HD1 would be a more interesting pick but the A1 would be the overall simpler and better option in my opinion. 1080i looks pretty darn good from it and that also gives you a little more resolution to make it into 24p if you want, whereas the JVC HD1 would only allow for 30p and, if you go through a pretty technical post process, could do a 24p conversion that looks acceptable.

The other reason to go for the A1 is the size, it's just so darn small and compact for such a powerful camera. I have a GL1 too and if you're aiming for something better, not HVX200/ JVC HD100U/ Canon XLH1 level, the A1 would be the best bet.

Carolyn McGrath March 26th, 2006 04:06 PM

Thanks so much for the feedback--which seems to indicate that I'd get better image results from Sony A1. But the issue remains for me whether that difference is enough to warrant the purchase.

Let me explain a bit...

I shot a documentary with the GL-1 over the course of the last 5 years--doing all the camerawork, interviewing, editing etc. myself. I was able to get quite a few screenings of the doc. at film festivals and at local universities, and I was overall pretty pleased with the outcome.

(I don't know if we can reference our own work here, but if so...and you want to see what I'm referring to, you can watch the trailer at www.contestedterritory.com).

I'm not trained in video--I was trained as a sculptor primarily--and don't have a ton of technical knowledge, but I guess I had enough to get by.

After completing the documentary, I took audio and lighting courses at DCTV in NY and was sort of horrified at all the "mistakes" I made on the video. I guess one of the main ones was not using XLR audio (because the GL-1 only has a mini input).

So, as I am now researching my next documentary--which will probably be done in the same way as the first, i.e. long term, one person show--I am considering whether the GL-1 is "good enough" for what I'm doing, or whether it's time to trade it in for something better.

Obviously, as I don't work professionally in video, I can't afford to sink a ton of my own $$ into this. I am already needing to upgrade my computer and FCP applications (they are also about 5 years old)--so I'm not sure if I can even afford a new camera. It's not like I'm going to make money off of this endeavor. My goal in doing the work is to get the ideas out there and to get conversations going about important issues. Of course, it helps if it looks and sounds good, but that's not where my emphasis is.

So...with these things in mind...what are your thoughts? Keep the GL-1 or go to Sony's A1?

Carolyn McGrath March 26th, 2006 06:22 PM

Some more details (excuse the length) which may impact your suggestions...

*the new documentary will be about farms and farmers--some of the shooting will take place outside, but some of it will be inside barns and homes

*I usually shoot with available light, although I may consider buying an inexpensive light kit for indoor work

Brian Wells March 26th, 2006 07:00 PM

Might look into getting a used Panasonic DVX100 (for $2k or less). It is still a MiniDV camera, but should fit well into your existing workflow and give you significantly better looking pictures than a GL-1 (yes, I have shot on both cameras). The difference is astounding. This camera captures light the way your eye sees it, with vivid colors, everything. Once you try it, you'll likely find it very difficult to want to shoot on anything else. Your work will look better. People always comment on the "look" of my work as being superior. I never got comments like that before using the DVX100.

Others will downplay the importance of beautiful colors favoring the higher resolution of an HDV cam. I see things differently. Hope this helps.

Kevin Shaw March 27th, 2006 11:25 AM

The DVX100 is definitely a step up from a GL1 and yields decent widescreen footage when fitted with an anamorphic lens adapter, but shooting anamorphic is a pain and without that the camera is basically obsolete as we head into the HD era.

I get a lot of positive comments on my HDV footage and the colors look good to me, which makes sense considering the 14-bit internal processing on the 3-chip Sony HDV cameras. But I wouldn't recommend any current HDV camera for indoor work without some kind of light, and the single-chip HDV cameras have significant artifacting issues in poor lighting. My recommendation would be to keep using the GL1 for now until you can save up enough money for a Sony FX1 or Z1U.

Carolyn McGrath March 29th, 2006 06:46 PM

I just want to get this straight: the lower end HDV cameras don't work well in low (i.e. available) light situations? If that's the case, seems that I'd do better sticking with the GL1 or switching to a better DV camera.

Douglas Spotted Eagle March 29th, 2006 06:54 PM

No 1/3 chip HD camcorder is great in low light. The Sony FX1 and particularly the Z1 are renowned for their clean image even with up to +13dB worth of gain. Because the pixels are smaller, light sensitivity is compromised. However, with the additional gain, you also can usually get as clean, if not a more clean image as most DV camcorders can get in the lower light. The CMOS cam's aren't as good, not just because they're CMOS, but because of the single chip process. If you can rent a Z1 for a day/night, I'd give it a go. It's definitely true that HD in affordable ranges is less light sensitive; but it's equally true that the Canon and Sony can seriously push the gain. Particularly the Z1.

Ken Hodson March 29th, 2006 07:39 PM

"The Sony FX1 and particularly the Z1 are renowned for their clean image"

Does the Z1 actually have a better low light image? I thought they would be the same.

Douglas Spotted Eagle March 29th, 2006 07:44 PM

This comes up a lot. Due to the additional/superior DSP programming, the Z1 indeed has a better low light image. Black stretch goes a long way as well, just as it does with the JVC.

Carolyn McGrath March 30th, 2006 01:00 PM

Perhaps I should clarify what I mean by "affordable." I can only spend $2000 or less on a new camera. So the Sony FX1 & Z1 are definitely out of my price range.

With that parameter in mind (and the fact that I am a crew of one making very low budget documentaries) would I do best to...

1. keep the GL-1 I have and get audio adapters (i.e. Beachtek) so I can get better sound?
2. get a different/better DV camera (i.e. used Panasonic DVX100, as was suggested)?
3. get a lower-priced HDV camera (i.e. Sony HVR-A1U or JVC GR-HD1)? Keep in mind...I need decent lower light/available light performance.

(Renting is not an option I'm particularly interested in.)

Thanks in advance for the responses...

Ken Hodson March 30th, 2006 05:23 PM

From the options you are giving, it sounds like your current cam might be the best bet. Look at your low cost options for upgrading your audio, maybe a DAT deck or one of the new mp3 recorders. Check your options. Spend your money on better lights, mics, filters, and software and hardware that will improve your image in post.

I wouldn't spend much money on a better DV cam given your budget and the impending switch to HD as a standard acquisition format. If your projects allow for additional lights in dim settings the 1-chip HDV camers might serve you well, but if you need to be able to shoot in the dark I don't think I'd recommend them. So either hold onto the GL1 for now, take a chance on the HDV cams or keep saving your money while we wait to see what other new cameras come along.

Robert Young April 5th, 2006 01:02 AM

I don't think there is one simple answer to your quandry. There are such a variety of considerations, as you can see from all the prior posts.
I would urge you to think about some of the following questions:

Format: Do you intend to stay in 4:3, or do you want to go 16:9 widescreen? This is a huge issue, because GL-1, DVX-100, PD-170 all have serious resolution/image quality problems in 16:9. The Sony A-1 is native 16:9 and looks very good even in standard DV acquisition

Editing System: Are you prepared to upgrade your system hardware/software to the level required for full featured HDV editing? If you need to remain in the DV editing realm for a while, the A-1 will acquire in HDV and downconvert to DV on the fly for firewire capture. An awful lot of people think that the downconverted HDV images look better than images shot as DV on these cameras. If you shoot in HDV, even if you initially edit and deliver as DV, you, or anyone else, can always go back at a later date and conform the original HDV footage into a hi def version of the movie.

Delivery Format: What happens to your movie when it is finished? Does it end up on a standard def DVD? HDV does enable you to produce a better looking DVD, but it's still standard def, and will definitely look like it when it's on a big screen. However, if any of your ultimate distribution channels would accommodate a hi def format- TV, projection to big screen, film out, etc. - HDV acquisition is going to make a very big difference. I have seen Sony HDV projected to a big screen. It looks simply stunning. Hard to imagine it came from an inexpensive 1/3" chip camera. It's a true quantum leap in quality. If your movie was shot on HDV, it can ultimately be converted to other HD formats, or film.

Indoor Lighting: I have used Sony PD-170s for a while. It is a terrific low light camera. My A-1 will not match it in a candle lit restaurant. However, with the gain up and black stretch on the A-1 will make a good image unless the room is really poorly lighted. Daytime indoor scenes with good window lighting are not a problem. You can also purchase cheap clamp on fixtures at Home Depot, use 250 w daylight bulbs, fashion some home made diffusion filters- and behold- let there be light! This would make your GL-1 footage look better as well. But, if you are shooting run n' gun footage with no opportunity to pay any attention to light levels, having a low light camera may be a critical factor.

Audio: Many people say that a movie is only as good as it's audio track. Having 2 XLR inputs opens the options for boom mounted mike, wireless, lavalier, hand held mic, etc. all of which are hugely better for dialogue than camera mounted mics. A Beachtek attached to the GL-1 would be good, the built in XLRs on the A-1 or DVX-100 would probably be better- certainly more compact to manage for a one man shoot.

Ultimately, people shoot what they can afford to shoot, and having a better camera is not the real key to making a good movie. But, it sounds like you've had good success with your first production. If you can significantly raise the production values in the next one, for a fairly small price, it may pay off when Discovery Channel, Sundance, or whoever comes knocking at your door.
I have switched to HDV. My Sony PD 170 is laying around collecting dust right now. The next step is to sell it and buy a Z-1. I'm never going back to DV. If a scene needs more light, I'll just get more light on it, tweak it in post, whatever it takes.
Good luck.

Carolyn McGrath April 6th, 2006 08:36 AM

So many choices...
 
Thank you, thank you, thank you all for the excellent feedback!

After careful consideration of all that has been said, I've decided for now to keep the GL-1 until I can afford a better quality HDV camera (or until lower priced ones perform better in low light). I'll be spending the $ I have available on a Beachtek unit and some good mics for the GL-1, as well as upgrading my mac and FCP application. Perhaps in a year or so, I may be ready for an HDV camera, and at that time, I'll be sure to keep all your good suggestions in mind (maybe by then used Sony FX1's will be available...).

Thanks again for all the help!

Tom Hardwick April 6th, 2006 09:16 AM

You know Canaon actually make an XLR converter for the XM1/GL1 Carolyn. It's called the microphone adapter MA0300. Not cheap, but a lot more compact than strapping a Beachtek under the cam.

tom.

Mathieu Ghekiere April 6th, 2006 10:48 AM

But the beachtecks are more rugged built and you have the chance to buy a certain model that gives you phantom power, which isn't the case with the MA300.

AGC sound issue with GL-1
 
Having done location sound on a "feature" shot with a GL-1, it is my understanding that there is no manaul level control on the camera, but that it always has auto gain (AGC) on.

While in many situations this posed little problem, I did encounter difficulties recording sound beside a busy street because the AGC would "hear" the loud background noise and gain it up as if IT was the signal I was trying to record. Then there was no headroom left for the voice to be recorded significantly louder.

The GL-2 does does offer a manual sound selection as of course does the XL series.

Tip McPartland

Carolyn McGrath April 6th, 2006 06:02 PM

Yes, but...
 
I'll respond to the previous posts, but briefly, because I think the thread is getting a bit off topic with all the discussion of GL-1's (and this being the HDV acquisition category...). Although, don't get me wrong, I'm happy for the comments.

Tom, Canon's MA-300 is comparable in price to the Beachtek unit, but is made for the GL-2, not the GL-1.

With regards to Tim's post, I don't anticipate the auto gain being a huge issue because of the types of sound recordings I'll be doing.

All things being ideal, I'd be getting a better, newer, all around snazzier camera, but for now, I'm gonna work with what I've got.

Thanks again all for the help.
