No, but they have the SDK so hopefully soon they will. Right now only Baselight is working with F65 raw files.

The HDSDI output is not usable for anything other then rough monitoring and it’s not even good for that when moving the camera like on a crane because of the massive frame delay. The camera is MPEG compressing and decompressing the video before it comes out the SDI as “10bit uncompressed” video.
The 35mbit on the SxS is as good as it gets with the EX1 and that is pretty good.

Yea Mark I got the ioHD for the same reason. I am pretty happy with the 35mbit, though it would have been nice to get pure SDI off the camera. We have a Aja IoHD in the LA area if you need one.
Do you have a EX1 in the LA area? We are doing some shooting of helicopters this Thrus and Fri and are thinking about using our EX1 if we can get Batts and another EX1.

Yes I have tried it with and without cards. I believe the MPEG compression and decompression is always running, and going out the SDI, which might be why it gets quite warm and goes though batt even when it is not recording.

Your right Mark there is no further compression to do, it’s the decompression back to a uncompressed SDI signal that is the problem. I think the signal coming out the SDI is video that has been compressed to 35mbit Long GOP MPEG2 and then decompressed with pull down added and sent out the SDI. So it is one generation old at that point. I think the SDI is really only for monitoring.

Hi Harcharan,
I was hoping the SDI would give best results, but after testing it with both a Kona 3 and ioHD I have concluded the 35mbit HQ mode off the SxS card is the best you can get off the camera. And it is very good, even when pulling keys. See the SDI post below.

Craig where are you getting your info? I can’t find anything that says it is from the head or block. If it is from the head before MPEG that is a HUGE benefit and should be used in sales material, it is not mentioned anywhere. In Oct at HD Expo the Sony guy with the EX1 told me that it was indeed off the head and truly 10bit 4.2.2 uncompressed. I believe he was wrong.
I am now certain the camera is only outputting the decompressed MPEG2 stream though the SDI port, here’s why.
I have digitized a live feed directly from the SDI from our 2 cameras both using a Aja ioHD to ProRes and also directly into our Kona 3 to uncompressed and it all looks pretty bad, the SxS is much better. The SDI should look alot better then the 35mbit off the SxS. It does not. No sighted person would have any trouble picking the image with the higher fidelity. Like others I wanted to be able to record from the SDI when doing green screen. The keys I am pulling using keylight in AE are very good from the HQ 35mbit SxS but really really bad from the SDI.
Also when at Band Pro I asked a direct question to Michael Bravin “Does the EX1 SDI output a clean 10bit 4.2.2 signal from the block before compression processing like the F900R?”

You are correct Craig in that the signal is a 10 bit 4.2.2 UNCOMPRESSED SMPTE292M/259M HD video coming out the HD-SDI BNC. Unfortunately it is not from the head like the Canon or a F900R. It is a decompressed version of the 4.2.0 MPEG stream that is being recorded to the SxS. So there is no advantage to using something like the Aja ioHD to bring in a better signal.
So I’m afraid, correct me if I’m wrong, that the video coming out the SDI is one generation old already.
Like I said this was a bummer for me, I hope I am wrong, but the video we are getting from the HDio off the SDI BNC looks worse then the 35mbit from the SxS. BTW the 35mbit is pretty damn good, I’m not complaining about that.

What about the HD-SDI? I was bummed out to find that no uncompressed HD signal out the HD-SDI port. The signal coming out is 60i after the mpeg. I had planed on using the Aja HDio to bring in 4.2.2 for keying, but no point in that as the card has true 24fps on it. I wonder if that can be fixed/changed with firmware?
I miss the old EX1 specs.
The bright side is after 30 days I have found 16gb media ($840) and batts ($240).

We have a issue with the HDSDI not being able to sync to a ioHD or a Kona 3 card. We put up some full frame pics at http://www.hd24p.com might be other issues.
