First HD100 24p Footage available for DL

The HD100 may also have such an ability, but I haven't heard of whether it actually does or not, or how you'd go about masking the pixels, if such a process does exist.

Algorithmically, it's really not that difficult; if the 'hot pixels' really stand out and they don't move or change, it would be almost trivial. (Even better if they show up with the lens cap on.) If someone donates a HD100 with a hot pixel to me, I'll have the noise removal filter in your hands the next day. ;)

Thanks for the thorough comments on the camera; definitely one to keep an eye on.

Barry, How'd you capture the HDV 24P? You mentioned a couple of different methods but which one did you use?

Those clips were all captured using the JVC Pixela capture utility. I verified that HDV Rack works as well, but I had already captured them through Pixela.

I can send you a link to a transport stream that was shot on 18dB gain with the iris closed, it has two hot pixels on it. If all you need is a few seconds of footage, that would be easy to arrange.
 
Ok, I got a question. How on earth do you edit this footage. I brought it into vegas 6, setup the timeline as a 1280x720 24p square pixel timeline. Everything shows up fine, but when I try to step through the footage, backwards, everything goes to pot. I get random frames and mixed pixelated frames that tell me nothing. Is there anyway to step frame by frame through the footage. NOte, stepping frame by frame forward seems to work, it is just backwards. This would drive me nuts. Do I have somthing set up wrong, having never worked with HDV footage, or is it just the GOP throwing things off?
 
Hmmm, never mind, it seems that the first clip is the only offending clip in the group. The other two allow me to step through them. ANy explanations, anybody?
 
Um... don't know. I don't have Vegas 6, for one thing. I just laid the clips on the timeline and they played -- slow as a dog, but they played. I used Sony HDV footage with Vegas 5 and it worked fine... I used JVC HD1 30P HDV footage with Vegas 5 and it worked fine...

Try using the HDV 720/30p project preset, and then change your frame rate to 23.976fps. Should work...
 
That is actually how I have it set up. I have noticed though, when I add an effect to the clip, like levels or curves, that the problem appears in the other clips as well. hmmmm.
 
Good work Barry, I look forward top seeing your next evaluation. It sounds like the dead pixel problem might be a firmware issue. I thought it was already confirmed that the camera should be capable of interpolating dead pixels and I'd be really surprised if the camera didn't have that capability. Maybe the algorithm in the firmware isn't operating correctly, and they need to debug the problem.

The dropout issue is a little troubling. The error correction routines in HDV are supposed to be much more robust than DV, so hopefully what you observed isn't a sign of chronic problems. I mean the whole point of the cam is to be able to lay down a true 24P HD image on a $5 tape for cheap and easy archiving and delivery.
 
one of these days I will eventually read more than the first post... instead of skipping to the end to post dumb dumb questions..
 
For Final Cut Pro there is a plugin from Digital heaven which will replace dead pixels.

It's called DH_Reincarnation and costs USD 10
www.digital-heaven.co.uk

I recently used it to fix a scene shot with a HDCAM HDW-750p (1080 25p), which had not been black balanced that morning (which also detects and maps out dead pixels).

Even in 1080 a dead pixel is very noticeable.
 
Man, with all these issues related with the HDV format, I don't think I will ever adopt it.
I am not just talking about the dead pixels, but the general dropouts the sony had and this one as well.

Yeah, seriously. Dead pixels, dropouts, and (correct me if I'm wrong here) not having firewire preview to an external monitor. These three things simply make HDV not viable for the work I do (narrative filmmaking). I need to see what it's recording on an external monitor AS it's recording. Not later.

Nah, HDV is simply not for me. I'd rather use my DVX in SD captured directly to laptop.
 
You can get firewire preview while you're shooting, but it's delayed a bit. You need a quite powerful computer to get full-res full-frame-rate preview with HDV Rack, but it will do it.

What you can't do with HDV is firewire preview to an external monitor in the editing suite, like we do with DV. You can't pipe a signal from your editor over to an HDV camera through the firewire and have it display on the monitor. You can print-to-tape, of course, but you can't preview/scrub etc.

Is it possible to get an SD firewire output from a HDV timeline? (I am guessing no because it would require even more processing power)

I am not bothered about having HD display while I edit, but I also don't want to be offlining because it makes workflows a real hassle, especially for quick jobs.

I see. But it still is no good if you can't preview via Firewire when editing. How are we supposed to check which clips are lit properly, are in focus, and are acceptable if we can't see it on a professional monitor?

But back on topic... This footage certainly looks better (on my computer screen) than the earlier HD101 footage posted here. But I'm not really impressed. It looks *bigger* than regular DV, but nothing more. I don't know... 4:1:1 color seems just too limiting right now. Meh.:lipsrseal

You've hit the nail on the head. "Bigger DV" is not better DV. DV gets better than smaller it displays. This has been my struggle with HDV from the get-go. It's a bigger image, but not a better image (color, latitude, etc.) In fact it's often worse than good DV.

I really expected much more out of this camera: that the CCD's, lower frame rate and other adjustments would result in a better image, but even if the quality improves under controlled conditions, I think my interest in HDV is about dead.

Despite the issues with HVX (price, media cost and last to market), I think Panasonic knows what they are doing.

High data rates, 4:2:2 color sampling and flexible frame rates & resolutions make much more design sense, especially after seeing this. As long as the HVX at least equals in latitude, it will exceed it color, resolution and compression artifacts.

Hopefully, Panasonic will engineer the HVX well; otherwise, I may stay put with my DVX100a and it's SD for some time.
 
hmmm.... I would like a HVX in a hd100 body... and the possibility to record ProHD too - got to shoot my sister-in-law's wedding tomorrow... it certainly wouldn't fit on a P2 card.

The JVC body does not do that much for me. The option to use other lenses is cool but I'm so used to the DVX100 series layout that the HVX appeals to me more. I'm not a huge shoulder cam fan because I shoot narrative and want handheld shot from different heights, not just the shoulder "ENG" look. That's one reason why I sold my XL1.

DVRig Pro plus Handycam works for me.

Per weddings, Firestore. HDV is too unreliable and you would want Firestore for the JVC anyway, so I see that as cost factor for either cam.
