Test Shots with HVX200

How was the feel of the manual zoom & focus? My biggest complaint of the mid-range cameras is poor manual functions.

I still do not understand this statement on HDV. I keep looking for footage that supports it, and there some issues we’ve seen on heavily leaved trees on a very fast pan.
But everything else doesn’t show it atleast over the last two months

What I’ve heard so far is that HDV actually holds together pretty nicely *UNTIL* you want to take it into post and start tweaking this and that, colour correcting, adding fx, etc.
That makes perfect sense to me. Just like taking a JPEG into PhotoShop and trying to make some changes. Forget it.
Has that been anyone’s experience?

Yes, HDV cam react badly to colour correction, but then again, so can DVCproHD – they’re both very compressed.

Aloha Steve and David,
I’ll tell you what made me think our footage from the FX-1 was breaking down under motion was viewing it on a Dell 2405 monitor. Now that I’ve seen a bit on a JVC CRT monitor, it is clear that the Dell monitor looks very blurry when displaying movement and has a fair amount of ghosting too. The HDV looked very nice on the JVC monitor and just attaching the camera to the Dell Monitor with no compression made the same smearing of the picture during movement. Turns out that Adam Wilt has already commented on these problems.

However, anyone that has only an HDV camera and a Dell monitor might think that it is the HDV codec breaking down, but that sure doesn’t appear to be the case.
Aloha,
Ken

I have only seen HDV on a large LCD for the home type of monitor and a 30″ Apple monitor. I guess I broke the golden rule, only look at the footage on a real monitor not a computer monitor. I will have to revisited HDV after your observation, maybe the obvious and constant motion issues I saw are not so bad on a real monitor, thanks for the reminder.

IMHO, a CRT HD monitor is the equivalent of Rose Tinted glasses. It makes everything look nice, even when in reality it isn’t nice. Plasmas, on the other hand, can make even nice video look nasty. LCD, I find to be in the middle – quite neutral actually, but remember, I mostly use my APple 23″ with the HD link to convert SDI to DVI.
You can, however, usually by panning over some trees, get artifacts in HDV that show up even on a CRT – they’re so strong that the “nice looking” CRT can’t mask them.
However, these are not the worst problems…. And DVCproHD and HDCAM have these problems too – it’s the problem of over compression, especially in shadows or “flat” areas of the video, which don’t show up too much until you try to pull detail out of shadows or do certain colour correction operations, when they really show up. It’s really over compression combined with the limits of 8bit video, where the natural dither noise that would hide artifacts is compressed away to leave a blocky mess. All HD formats that are even half affordable have this issue.

[Chris Elley] “The 60 fps had incredible results.”
Glad to hear. Sad to know that Panny decided that we Europeans do not need 60fps…

Graeme,
I agree that the CRT’s are probably giving us an image that nobody will ever see again since they are going the way of the dinosaur. The things I was seeing on the Dell monitor go beyond the types of artifacting that you are describing though (and I agree would smoothed out on the CRT). When most of the frame is in motion the entire image goes very soft on the Dell, almost defocussed or blurry while it stays sharp on the CRT. This also happened when we hooked up an FX-1 with component out to both monitors simultaneously and just did live pans around our studio (no record to tape, should be no MPEG compression from the camera). The Dell showed the same effects and even had some ghosting. Hard to know if this is a problem with A/D conversion in the monitor or how the Dell handles interlacing or maybe even our monitor is not working properly? Guess I should look into that as well. LCD’s as a video display are pretty new to me and we don’t have a lot of things to compare it against. But it really made me think that the higher motion footage from the FX-1 was trash and it certainly doesn’t appear to be (though I won’t quibble about the other kinds of artifacts you mentioned). We do have a new Mac Quad on order with a Kona board and a 23″ display and will probably get a converter to use it to view video on. Do you have a preference between the lower priced AJA converter and the BlackMagic one (HDSDI-DVI)?
