The New HD/HDV Cam’s

Thursday, February 2nd, 2006

Holy frickin’ crap. Just back from Snader’s, w/ some hot hands-on reviews:
The Panasonic HVX200 has a great viewfinder, much better matched with the lens than the DVX100A. The image & quality reminds me strongly of the PD150 viewfinder. Peaking has a very tight range, so it’s clear when you’re focused. The camera has decent build-quality overall, & a pretty-great lens. Fantastic quality imagery, especially in still shots, as noted in Wilt’s DV.com article.
The JVC GY-HD100U: I had pretty-high hopes for this camera, mostly b/c of the promise of true 720/24p HDV & that Fujinon mechanical lens. Well, it does have the mechanical lens, & it is great… but there some annoying issues. First, JVC still hasn’t defeated that ‘vertical line’ problem. If you look closely, there is a faint vertical line visible in the footage (kinda like the horizontal line on old Sony Trinitrons), with the left side of the frame tinted reddish, & right side brownish. We tested an old camera (really obvious, even at 0dB gain), & then a brand-new one. The new unit had the effect much less, but still present: the ‘line’ was obvious at high gain, with the same left/right pink/brown chroma tinting. At 0dB gain, the ‘line’ was nearly invisible on a 50″ Panasonic plasma monitor, but the pink/brown left/right tinting was still distinguishable. And that’s not all– as Wilt noticed, the footage from this camera is remarkably noisy, even at 0dB gain… & this was shooting a ‘demo viewstage’ (ie, ‘beauty-shots’) setup by Snaders for the camera shootout(!!) But the manual lens is great. And the viewfinder is not bad… but the peaking has a pretty wide range, so it’s not clear where critical focus is. Overall, a miss (& we haven’t even talked about motion-footage yet).

The Canon XL H1: Bigger & better-built than the original XLx units. It’s more solid, & a bit heavier, but the ergonomics have been improved — it ‘hefts’ better. It’s the first XLx form-factor whose ergonomics ‘make sense’. Plus there’s that fantastic-quality, long lens. However, that lens has the non-mechanical ‘fly-by-wire’ action… which is somehow not as tight/solid as the HVX200’s. Also there’s notibly more ‘breathing’/drifting as you rack-focus. And the viewfinder is gawd-awful compared to the other two; it’s extra-gained, with a ‘dot-grille’ effect which just looks crude. Peaking is pretty good, however.

…& now let’s talk about HDV -vs- HD in the actual footage’s “quality of motion”. It’ll be an in-depth, technically succulent comparison. Here goes:
“HDV sucks, & HD wins.”

That’s it. There’s really no better way to demonstrate this, than to let the Manufacturer’s do it themselves:

Canon: for the Canon demo, all the HDV motion footage was captured via HD-SDI to DVCProHD 100Mbit playback. Oh really! The only HDV capture + HDV playback was a series of locked-off shots with minimal intra-frame motion, & zero camera-motion. The Canon Rep back-pedalled to the audience: “well, you really need to show ‘beauty-footage’ in Demo’s like this”. He didn’t have any HDV-captured motion footage to play-back in native HDV.

JVC showed HDV-captured footage, but of well-lighted interiors. No long or wide shots.

Panny otoh showed long, short, outside, into-the-sun… all clips have been previously posted online, but now seeing them via high-end projector, they were stunning. They also had a 3-way footage-comparison clip, showing where motion, chroma, & noise artifacts really hamper Canon, Sony, & JVC’s HDV. But the best thing? The Rep was more-than-willing for me to shoot several minutes direct to P2, & then play-back on the Panasonic production monitor. Whip-pans, difficult lighting, crash-zooms, speedy rack focuses… the HVX200 ate them for lunch, w/ beautiful flesh-tones & over/undercranked footage to boot.

Conclusion:
I’d speculated before that even if the new Panny HVX200 had good imagers & lens, they would probably attach a not-great viewfinder to it (ie, “you don’t dare shoot features w/o a production monitor”, a la DVX100A/B). Well, I’m wrong, & thank bog. Sure the P2 cards are expensive, & the FireStore 100GB drive even more expensive. Regardless, this camera, in the right shooter’s hands, is going to step all over the SDX-900, & Sony DigiBeta. The jury’s still out on footage comparisons with Varicam… but it’s increasingly hard to see the difference on a large HD production monitor, let-alone on medium-end (circa $4,000) HD projection. All I know is, the camera was absolutely mobbed by working Documentary DP’s & Directors, all putting in their orders, and/or building up their chops for upcoming gigs. Welcome to the future.
And Sony? The only conclusion from the multiple working DP’s I’ve talked to: “Sony’s HDV has made all the wrong decisions” and “Not useable for exteriors, or run-’n-gun, b/c of the codec difficulties”. The [only] good news for Sony: lots of ppl like the new A10. I saw nightclub footage at +18dB gain which looked darn good… low grain, decent latitude, & the red’s had almost nil chroma-bleed. Wow. Too bad you can’t set aperture.

“Truth” & the ‘net

Wednesday, February 1st, 2006

When we think about ‘research’ lately, we all grab out computers & go to Google.

Why?

B/c it’s convenient, sure… super-fast, & there’s tons of information there.

But just think– Google & all other search engines are designed to sort information by ‘page-hits’… or in other words, “Truth as measured by popular approval”.

But if you think about it, that’s silly– all the major creative & scientific discoveries in the history of the world, were made by ppl who did NOT think the way others thought… in fact, they often so ‘thought different’ that they were ridiculed, ostracized, or even put to death.

In two of the fields that I operate, namely internal martial arts (Instructor since ‘93) & the Chinese game of ‘Go’ (4dan AGA), what’s written about these practices is most-often wholly incorrect. Most of what you can find (online or otherwise) is just ppl writing what they ‘think’ is true, & others writing what they ‘heard somewhere’. & so what you get is misunderstanding followed by misunderstanding.
Small wonder Vernor Vinge calls it the “Net of a million lies”.

Next time, check if the person speaking or writing is calm, reserved, casual. Or are they strident, super-certain, possibly defensive? The former sounds like a person with personal experience… & the later isn’t.

But best– find out for yourself.
