Excellent Jarred,

& I see you put up a site for the other camera.

This is getting really good!!!

Keep up the good work.

Hi Jarred,

It was a please speaking with you and thanks for creating the new forum space for us. Any chance of getting it brought up a level to be visible at the top menus?
 
This seems like the pro camera for our next venture. Kudos to all. Also this brings back manufacturing to the good old US o A, Bush notwithstanding.

considering there are only 1 post posted here every couple days, it doesnt justify a greater exposure.
 
Ari, you should also try an get a good spot on dvinfo.net they do not seem to be biased towards any one camera. It looks as if though Jarred is only really supporting RED. And by saying that, i mean he's pushing it to death. While your SI-1920 camera seems more in the grasps of our hands today.
 
well so much for the thanks jarred for the dedicated forum.. Dont think this will last very long if im going to start being called out.

Red approached me 6 months ago, and they go their own forum last month when demand started to call for it.. Ari contacted me last week.
 
Jarred,

We really do appreciate the attention you are giving us and the fact that you have recognized us by establishing a dedicated area on your site (within days from our initial contact).

What is the best mechanism to communicate to the users that we now have this area?


Thanks,

Work your butt off on the camera and continually share the results here in the forum! The rest will take care of itself.

To answer a question you had previously "how small/light would you like it?"... the obvious answer is "as much as possible". I guess this thing is basically a tiny camera head attached to a small-form-factor PC, which obviously limits the size and power requirements in ways that cameras like the HVX don't have to deal with. And having a removable camera head does help in most of the situations where size would be an issue, actually promoting a design like this above more traditional integrated cameras. But siize and power are nonetheless an issue, and no one wants to have to buy thousands upon thousands of dollars of batteries to do a day of shooting on location. (Although if the camera delivers on everything else it could well be worth it.) ;)

Could you explain a bit more about the recording interface? From what I can tell, it's a stand-alone app on the attached PC that uses the touch-screen-style interface to control all the record funtions? And to give you display features such as zoom (for focus) and that sort of thing? And this app records .avi's? Which are then subsequently available to Premiere (or anything that supports the cineform codec)?

Please, correct me on anything I'm wrong about from that vague understanding of your workflow.

Cheers,
Kevin
 
Kevin,

Yes you are correct. We currently record to .AVI but will have QT support as well. The UI is completely touchscreen driver, but most critical controls are also mapped to CTRL keys so we can map USB botton devices, as well.

The EVE (SI-1920HDVR code-name) is an integrated camera and embedded PC system with a USB hot-swap HDD cartridge system at ~65W consumption. The Camera head (optical block) is detachable and can run over Gigabit Ethernet and 12VDC (~6W) for head-on-wire/POV operation. Here is a rig the "Spoon" film production is using. An LCD monitor is attached to the top of the camera for focus and composition, but all controls and recording is being dont from a separate workstation.

You get an in-depth look and explanationat of the Camera/UI and Cineform workflow fron the Studio Daily video interview.

Regarding size, is there a point where the camera becomes too small to fit comfortably on a shoulder and operate with accesories attached?

We want to build the highest value D-Cinema camera and workflow. We need your input.

Ari, might I suggest naming this camera something a little more memorable. I was telling a DP friend about this cam system the other day and couldn't even remember what it's called. Also, Sony and Panasonic have sent me a few DVD-demos to check out on my home theater system which is a great idea because watching scaled down footage on my PC is a pain and never looks right. Do you guys have a demo disk available? I'm considering purchasing your system and I wouldn't mind sharing a demo with a few DPs I know.

One last question I have relates to the ugly video smear that's often present in HD-originated movies. I generally find that the motion of 24P HD video to be fine but sometimes I notice the dreaded ghost trails or video smearing, even when a subject is simply walking. Have you guys found this to be present in your tests? It's a dead givaway of video origination. Does this have more to do with the shutter speed or is it a hardware/medium issue?
 
The "smear" is from an "open" shutter running at the full-frame time. You can see on our website from the WMV files that the shutter looks pretty good, there's none of that nasty open-shutter "smear" that screams "Video!"

Thanks,

The Aaton A-Minima is a very little camera, and it feels AWESOME in my hands and propped up against my shoulder. The wooden hand grip makes it a pleasure to hold and operate. Ahh, if only DV cameras could be so comfortable.

I don't think you can make it "too small" to be honest. But, it needs to look sexy. See the Arri 235? THAT is a sexy looking camera. It needs to have a good fit and finish, otherwise I would be embarrassed to use it. Honest.
 
Yes I saw the Studio Daily video-- very interesting, and informative, but I just wasn't entirely clear if I had understood everything correctly.

I see that the software allows for zoom for focus and some sort of highlight display function. Is it also going to provide more 'traditional' displays such as waveform/vector-scope/histogram-style displays? That could be very useful.

Also the ability to easily view a reference image would be nice. e.g. If you're doing reshoots of a scene for example, being able to switch easily between monitoring an image from the previous shoot vs. the live feed is very helpful getting that hard-to-achieve consistency/continuity. Such a thing can also be helpful when shooting outdoors in constantly changing light, or for referencing storyboards, etc.

OK I have about two-thousand more suggestions/questions, but I'll let you get these implemented first, let me know when you're ready for more direction! ;D

Kevin,

Keep sending the suggestions....!

1.) Histograms are already high on the list. Waveform and Vector are not. The color doesnt matter in the camera. You can create any look you want in post from the RAW (digital negatives). Between Histograms and the exposure meter and, oh yeh, touch point metering anyone should be able to set correct exposure without clipping.

2.) Reference Image...YES! I like your suggestion of the A/B comparison to make sure everyone/everything is aligned and on mark. We would enable a playback of a clip, freeze on a frame and store it in Ref-A memory. Then during live mode you can cut back and forth between the stored ref frame (A) and live feed (B). We have also discussed A+B Live (A) plus Frozen (B) with 50/50 brightess or overlay...Do you think that mode would be useful?

Awaiting next instructions....
