Don't forget that many monitors can only display in 8-bit, so even changing this setting will not appear visible on the screen (even though it is in actuality).

I remember reading somewhere that most monitors do support 10bit. But, at least in Windows, unless you have a Quadro video card, or FirePro, you won't get 10bit colour.
Look into ffmbc, it is a fork of ffmpeg that supports ProRes 422 and 4444, might be good for making proxies.

Also, ffmpeg supports Photoshop curve files (*.asv), if you could figure out how to create a curve file in photoshop that mimics Canon LOG, or whatever other curves you want to try, you should be able to use it.

It also supports luts, and 3d luts. Including 3d LUTs made in DaVinci resolve.
130mkm is 130 microns(mikrons)?

Which I believe would be 0.13mm.
You need to make 2 videos, one showing what you did, and another showing example footage!
I was wondering if someone could explain why you can't record 1920x1080 60fps in 1:1 crop mode?

Is CFast technology worth the look?

CFast is simply the SATA version of Compact Flash, which is PATA(IDE). It would have been nice if Canon had made the 5d3 a CFast device, 2 slots, 1 CFlash, 1 CFast!

no, i reverse engineered the software.

Could you be more specific? Maybe more people can help?

I've been looking through the ML source code and I can't find anything for setting CF modes.

Which got me to realize that the CF subsystem has to set the card mode prior to the ML firmware even being read.

So this means that what would happen is ML would be read, the CF card would need to be "unmounted", the CF mode would need to be changed (if that is even possible in software), and then then CF card would need to be remounted, or something along those lines. Roughly speaking.

the camera is *not* using true IDE mode.
but i hope to be able to hack it so it will only send ATA commands.

How do you verify this, did you check to see if Pin 9 is being held low when the camera is turned on?

There are only 2 other modes it could be running in, IO Transfer or Common Memory.

Hey Guys,

I just got word back from china, and my guy found those CF adapters, but he wrote me asking:

"OK, I able find one in china.
I want confirm you need.
It's IDE host to CF disk?
CF host to IDE disk?
CF host to SATA disk?
IDE host to SATA disk?
Just tell me you want ,clearly."

Which one do we need guys?

CF host to IDE disk, or CF host to SATA disk.

I would get one of each, if the SATA one doesn't work, than the IDE one would be the fall back device.

Hey guys,

yesterday, i got from Esscable the setup on the picture above for testing purposes.
Big Props to them, they did a really good job and are very interested in further development  8).

So know we can start - but i need your help, too!

Momently I got following things on my desk for the big testing setup:

- 5D Mark III
- Lexar USB 3.0 Cardreader
- Esscable CF Extender female-to-female
- Esscable CF Male to IDE female adapter
- Esscable IDE Male to SATA Converter
- CF Extender from Calexium/ France
- CF male to IDE female adapter
- OWC Mercury Legacy Pro 2.5 IDE/ PATA SSD 60 GB
- Seagate Barracuda 2TB SATA
- 2x 2.5 HDD Adapter - 2.5 to 3.5 IDE Adapters with power support
- IDE Cable
- CF 1000x Komputerbay 32GB
- SD Card 32 GB Sandisk
- Power Supply

I have the possibility to solder an individual cable. I have naked cf-female ports and 50 pole 0,635 cable. Therefore it is very useful to have a cf-ide mapping.  sb. should know that!?! Until the end of the week i will get an old canon cam with cf, so we can test - and my 5DMIII won´t explode  ;D.

*** First testing setup! CF to SATA

What I first tried is the esscable setup - because they told me they tried it and it works for them.
USB-Card-Reader connecting to my MacBook. Don´t work.
When I get the CF Extender in the cam instead of mac - Nothing happend - no possibility to start the cam - (only in IDE the cam said can´t format the camera, unsupported drive)

*** Second Testing setup with IDE:

Esscable cf- extender to esscable cf- to ide to ssd with ide cable adapter- powersupply from pc.
Camera said after loading about 5-8 seconds - during no lights are blinking - 

No access to card1 - new card insertion or replacement or format with camera.
-> Formatting Impossible - change card!

When I connect the setup over Lexxar card reader OWC (exFat formated) will be connected.

*** The cf-acc plugin don´t save a VRAMx.BMP File! How can i get this to work!

When I push "Read CF details (MAY CAUSE ERR)" the cam is doing sth. because light is blinking every 5 sec. until camera went off.

With the IDE hard drive, is it set to Master, Slave or Cable Select? If it is master, try cable select, and vice versa. That is the only thing I can think of going wrong with this option. Maybe try a different IDE drive?

As for your IDE to SATA adapter, which one specifically is it?

Is it this one > ?
What about streaming the data? or is that already done? or is it even possible to get that low level?

The ATAPI-7/UDMA7 standard included a new streaming command set specifically to benefit audio/video devices that use hard drives.
ES&S Kabel should just make the right-side CF card (in the photo) into a box of some sort, and put IDE to SATAII circuitry in it, using the ARC772 IC which can support 200MBps, as well as a SATA port. Then instead of using the flat ribbon cable, use a rounded ribbon cable.

If they can't (or won't), then we can just get a CF to SATAII adapter, and skip the extra CF to IDE adapter step. Like that Lycom ST106-2 device.

We should also petition Canon to put a CFast slot in their next camera, lol.

Hey guys,

I think there is a much simpler solution to do this with off-the-shelf parts. 

There is a CF to IDE adapter manufactured by Fabia Tech in Taiwan that basically exposes a standard 40 pin IDE connector at the end of a "dummy" CF card:

It seems to be rebranded by ES&S Cable in Europe:

but I haven't found any US resellers.

You can then use a standard 40 pin cable to connect it to this SATA device to IDE host controller adapter manufactured by Lycom:

It's rebranded by Rosewill in the US:

And seems to be also available from ES&S Cable in Europe:

The spec says it supports ATA UDMA mode up to 150MB/s.  The SATA side will not be a problem, as it's much much faster.

You should then be able to use any SATA SSD drive, though you'll need to supply external power to it.

I am not sure how much the CF-IDE adapter costs, but it seems to be all passive electronics - just a wire mapping.  So, I can't imagine it being too pricey.  So, without the SSD and the power supply, I am guessing it's less than $50 to try out.

Hope this helps!

Good find on that Dummy CF card!

I guess we just need to find out if it will all work together.
This is a real head scratcher of a problem, without going the custom route that is.

Makes me wonder if we could order a CF connector that you don't need to solder, maybe it is a pressure/snap fit, and then do the same with an IDE connector, with the appropriate wiring that is. Still custom, but a helluva lot easier.

But I am not sure if the host would recognize the hdd as an IDE device.

Anyways, Digikey sells both connectors, a female CF card socket (1), and a male IDE header (2), we don't have to use these exact connectors, but its so crazy it just might work.

They also sell an entire CF card "kit" (3), which reminds me of PCMCIA cards with that thick part at the end. If we went this route, we could even maybe hire someone to design a circuit that connects the CF side directly to a SATA bridge IC and a SATA socket.

Click the datasheet for more information on the part.



I'm working on a similar idea myself, although I hadn't come up with a solution for the door yet.

Lots of ideas, thin ribbon cable like FPC/FFC, a modified replacement door with a SATA port in it, a CF card/door combo that was 1 piece with a port in it.
ffmbc lets people on Windows encode in ProRes 422 and 4444. You should slip that as an option into your code, so people can choose between CineForm or ProRes.
