What will give better results…?

[John Ryan]

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.

John,

Have you tried the SDI out to the AJA I/O with your sxs cards removed from the camera? Someone on another thread mentioned that the signal might be different with the cards removed. I am considering the AJA but after your post I am now unsure.

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.

Hi John,
Here is wishing everyone a Very Happy and Prosperous New Year.
Thks for your reponse.
But can you please confirm that Avid Composer will support full raster 35MB files from EX 1.
I was also wondering then whats the use of such high priced equipments such as the Adrenaline..apart from HD mastering…
Are are we seeing a death of such expensive IO boxes and the decks?
Your views…

John,

Thanks, now I have one less reason to party tonight. One of the main reasons I got this camera was to marry it to the AJA io hd and a laptop. Do you happen to know where I can rent an AJA io hd in the LA area?

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.

John,

Yes I have an EX-1 in Long Beach but I just got it and I’m testing and shooting every day for a while. Sometime after things settle down a little I’d like to plug into an io hd and see the problematic footage for myself. I guess I just can’t get over the idea that Sony would spit out GOP compressed then uncompressed from the SDI. Especially with Canon providing true uncompressed straight from the head.

Hi,
I just went to the AJA site and really the AJA io hd is an
excellent product.But just one querry:
1. Which Laptop is recommended for on field acquisition?
2. Which storage drive is recommended?

With an AJA io hd available roughly for USD3200 or even less
I think it is totally worth it.

Can you please post the results of your tests.
Thks

John,

[john conner] “Yes I have tried it with and without cards. I believe the MPEG compression and decompression is always running, and going out the SDI”

Since you’ve tried the HDSDI with and without cards in the EX1 without satisfaction that squirrels my supposition that perhaps the HDSDI out was different depending on whether it was simultaneously recording to cards or just presenting an EE signal.

I would think that others on this forum would be feverishly testing the HDSDI output of their EX1’s to find out whether the signal is truly 4:2:2 uncompressed off the camera head or decompressed from the MPEG2 stream, but so far that’s not the case. I’m left to wonder whether your experience is universal, or if you have a bum EX1, or if Sony has intentionally down engineered the HDSDI output? I hope we find out pretty darned soon.

Good Luck to you,

Ron,

I have the EX-1 but I don’t have any way to view the signal. No SDI in to my computer and my 20″ HD production crt only has component in.
Does anyone know if I could go SDI to HDMI? I could view that on my 37″ HD LCD.
