HP "ripoff" project with EX1...

Yes, I heard that they offered the 120fps and a peak type focus assist.
The Red is getting better and better...

I think that would limit us to 30 fps maximum?

If you record on a 720p24 timebase, and set S&Q to 60, don't you end up with full quality 24p footage (unlike recording on a 720p60 timebase, which crams 60 frames into the same 35 mbs stream)?

Any UK based shooters with a RED?

720p 60fps is part of the HD-SDI spec and I confirmed that I can record it from the EX1. However, that is timebase 60fps, not 24fps recording 60fps slow-mo... at least on the capture system I have, which is getting long in the tooth.

I believe you're right about a timebase of 24fps using 60fps slowmo having full quality bandwidth applied to those 24 frames making up a second... but have not personally tested. I should do that when I have a bit of time.

UK RED's are plentiful... check on the REDUSER forum in the "for hire" section, I know Paul Clement has one and he's a good bloke!

I'd sure try out a test with the EX1 and native recording first before looking elsewhere...

As to the RED and the faster shutter... the windowed modes provide a way to allow faster triggering, reducing the rolling shutter skew as a nice side effect, 120fps was always a target, but originally only with 720p... at one point that spec changed, as they moved away from "broadcast" output formats, and the new target was limited to about 96 fps 2K. 120fps 2K is great and a surpise to me...

HDSDI with Blackmagic

HDSDI with Blackmagic

Hi Jim! you mentioned the Blackmagic Intensity card for capturing HD-SDI. Do you mean the Decklink series instead ?
Intensity only captures HDMI, or component.
Just wondering which card would work with the EX1..Cheers!

Thanks everyone!

To answer some questions, I just recorded to SxS card, no HDSDI used, even for the greenscreen. I am thinking about putting a BlackMagic Intensity card in a small PC system for capturing HD-SDI to either PhotoJPG or Cineform down the road for super-critical key work, but that's the only reason I'd do that.

Yes, the RED is a great camera... but when it came time to make the final decision, I looked at the first handful of jobs I had booked and the RED wasn't the best choice for any of them. That was an eye opener...

...One project was a green screen "premiere night" arrival of a limo and tons of flashing strobes. No good for the RED, or the EX1. The next was a series of green screen talking head interviews in a distant city, and I only had the budget for myself and one soundguy/assistant. No good for the RED, plus the client didn't want to deal with the RED post-flow. And on and on.

Since the RED and the EX1 have the same basic "faults" in regards to rolling shutter, neither of them were appropriate for some of the projects... not good if you've got 35K invested in the system, but that's tolerable if you've only got 8K in an EX1.

I do look forward to revisiting the whole RED concept again down the road. In fact, if Adam Wilt doesn't do a direct RED/EX1 green screen shootout test, I'll do that in the next few weeks.

Well, the Intensity card in combo with an HD-SDI to HDMI converter would work... probably the Blackmagic converter is the best bet, as it's the only 10bit minature converter that I'm currently aware off.

In addition, you could capture analog component from the EX1 via the Intensity Pro's component connector, I believe... and as far as I know, the analog component is before even the conversion to HD-SDI internally. So many possible options.

Of course with these HDMI solutions you're doing external routing things to get audio and timecode, as far as I can tell. Different HD-SDI to HDMI converters handle audio differently. Some mix the signal into the HDMI stream, others (like the Blackmagic one) feed it out to RCA connectors.

But yes, you're right, the Decklink series would be more "ideal" for HD-SDI capture from the EX1, since you would have audio and timecode and stay 10bit for the capture. However, if you own one of the HD-SDI to HDMI converters, then you could explore the Intensity and Intensity Pro options for a budget solution. And how important 10bit processing is to you is dependent on what you're ultimately going to... for instance, PhotoJPG is 8bit, while ProRes and CineForm would benefit from a nice 10bit processing chain...

I know I'll be spending some time at NAB snooping out the details for a nice solution and will share what I find out in regards to these options...

Awesome.. Forgot about Component capture. I have an Intensity Pro lying around here anyway.
So I have my Intensity capture station and my Intensity Pro card which can record via component. I am about to buy NeoHD anyway - that does it well I reckon..
If the analog component is before the conversion to HD-SDI - is that better or worse ?
I guess another way of asking is - is the A/D conversion better in Blackmagic or the EX1 ?

I would imagine it is better via the Blackmagic card. I've seen various posts from the Blackmagic folks indicating that all aspects of their line of cards from the cheapest Intensity to the Eclipse that are shared between them are of equal quality (i.e. A/D conversion, scaling, etc.).

The analog signal from the EX1 can be "sampled" at any bit depth, the value of that sampling of course has finite limits, but it's safe to assume that you'll get your 10bits worth out of it. Of course the analog connector is fragile and the signal can be interrupted compared to the HD-SDI out, there's no timecode in the component signal, etc... still, all in all a worthy experiment to try.
 
For those interested, I e-mailed BlackMagic tech and the Intensity-Intensity Pro are 8bit cards... so, not the best choice if you intend to export your EX1 analog or HD-SDI out to 10bit ProRes or CineForm and kept it 10bit. The DeckLink HD is the way to go.

ahh Jim you don't need a RED. It would just slow you down. You should just get a super freaky sneaky geeky EX setup. Paint it red. :)
 
I got it Jim instead of a black magic card or ProRes go for that new Convergence design 100Mbps recorder. Won't slow you down and will give you some mean greenscreen and will work with most cameras. Yeah I should be a consultant.
 
I actually know the Convergence Design folks personally, as they are based in my home town near my favorite eating establishment. :).
