Sony FX1E to hard drive 4:2:2? 10 bit? indie film/HD solution

I own FX1E. The camera head puts out uncompressed 1080i analog output, which I believe is 10 bit. Is there way to attach hard drive to uncompressed output? Would you get 4:2:2, or what is color sampling? The cameras that you guys building here are great. But using FX1 would give built in viewfinder, etc.

You could disconnect hard drive and use camera as a regular camera.

You get 1440x1080 pixel resolution. You have it deinterlaced by with DV film software. In worst case where everything moving you end with 720x1080 pixels progressive image. That is good enogh for me.

Can the hard drives, micro computers, etc. that you are building here get interfaced to Sony camera? If not, do you think someone may come with a solution soon?

Is image out of uncompressed analog output equivalent to 10 bit? Can you get 10 bit quality out?

If FX1 would not work in this kind setup, maybe Z1 would.

Am I missing something?

How much would recording device cost? Would it use some kind of built in compression? If someone is working on such solution, when you expect it to be available?

Is 10 bit uncompressed image lot better than compressed 8 bit image?

Will new JVC HD100 be compatable with such device?

Radek, I think it's more effective for you and future readers to post these questions on existing threads, because they are very specific. I'm sure people who can answer your questions are subscribed to the thread you could be posting on, so they get your question directly by e-mail.

Just a thought though.

Radek.

Visit P+S Technik website. They seem to be doing something like this.

Radek,

Have a look at AJA Kona's A/D converters and Blackmagic-Design multibridge. They allow to convert the analog component output of any camera into a digital 10 bit signal to be recorded by any computer that comes within their specs. You can use your camera to record on tape as well (HDV or DVCAM). The tape could be used as a backup (!?!) or as source for the off line editing. If you are happy with a tethered set up, way to go... and don't dream to shoot run & gun style.

Analog is analog and digital can be 8, 10, 12, 16 bit.... your choice and budget! The higher the better and MORE EXPENSIVE. Depends on the codec you use and your requirements or needs for post production.

Thank you. But you have haul around big computer. Is there small computer that could be used, like laptop or small factor computer that works on batteries? Would you be able use the laptop screen as monitor at same time? If you used laptop, would you need separate RAID drive? I don't want to haul desktop around. Any suggestions? Could the computer compress the data gently?

I think essentially what Radek is saying, instead of using those single cmos cameras (aka 4:4:4 homemade HD threads) why not use 3 CCD 16:9 native 1080i (i.e. the fx1) as the CAMERA HEAD and build around that (since it outputs analouge signal)

here is another idea, why not make a wireless transmitter (or modify one of those TV signal senders) and have a computer with the receiver? i.e. FX1>>anolouge video signal >> wireless transmitter (TV signal sender/modified) >> receiver>> A/D capture (eg blackmagic) >>PC>>harddrive. That way you can shoot without building a portable computer solution

Transmitting 1 Gbps from antenna on camera would probably fry your brain pretty soon. If you use HDSDI converter at camera, how far could you run coax? Is there HDSDI converter with fiber optics output? You could probably run that for miles. How much is some small battery powered HDSDI converter?

Now if we could change lens for Fuji, like Italian guy did, or use relay lens and home made Micro 35 adapter that will go on sale for $500, we would have super camera to make movies. I just wonder if quality after conversion is really 10 bit. Does anyone know?

Radek,

If you look at AJA KONA and BlackMagic websites, you'll understand better how the compression of the analog signal to digital is done. The moment you go into the HD zone, a RAID 0 drive config is a must.

I have seen a small box that can transmit a component signal over CAT5 ethernet cable:

I wonder if there is any signal quality loss or interference issues.

720p, maybe it could support 1080i soon...
