With a theoretical limit of 1.2 gigabytes a second, would a CF-to-HDMI cable adapter be an option to look into? I am working with a computer hardware engineer in Irvine on getting a functional CF-to-SATA prototype up and running, and the HDMI idea came to mind.

Pros to the CF-to-HDMI interface would be the aforementioned 10gbit/sec limit, but also the ability to record straight to a number of pre-existing devices, such as the Atomos Ninja2. Doing so, to the Ninja specifically, would give us ProRes .mov's, as well as the ability to monitor what we are recording.

Just a thought. I've already funded his research on the CF-to-SATA, and we are in the process of designing a Canon LP-E6 powered SSD dock.

Don't mean to digress from the development chat, but what so you suppose the cost would be to have a manufacturer develop a one-off prototype for this?

N/A, what's you're premiere workflow?

Seeing as Canons 1.2.1 firmware update is just that, a firmware update, I don't see it unrealistic that the magic lantern team could figure out a way to replicate the clean HDMI output on 1.1.3. I've been using my ninja2 on the 5D3 for sometime now, and think it's an excellent "liveview" monitor. It also works well with the five D2, as long as you have no GUI overlays.

I've also put in a request to a friend that works on the front end development team for Illustrator & Photoshop. He just so happens to be a Canon user, and loves ML. Well see if be can pull anything through. I'm also acquainted with Andew Kramer(videocopilot.com), and he's a fan of the team. He's busy with Bad Robot right now, but he did seem keen on fiddling with it if he had free time.

I just stumbled upon a Gizmodo article written almost literally one month ago today, about a new lineup of SD/CF cards from Toshiba. They claim a min/max speed of 65/150 for CF and 60/95 for SD.

Article: http://gizmodo.com/5995439/behold-the-fastest-cf-card-ever-made-for-now
Amazon SD's: http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313.TR8.TRC1&_nkw=exceria+pro&_sacat=0&_from=R40

$84usd for a 32gb SD that boasts 95wr could be great if development on a 12bit or 10bit compressed rate is mastered.

I'd love to see some benchmarks on the SDs, as they look promising on paper, and are very affordable. Maybe throwing a high-speed SD into a more affordable low-storage-high-speed CF adapter? Im probably blabbing on now after going 32 hours without sleep, but a more affordable solution is exciting for many. I had to throgh out an extra $6400 to get two more 5D3 bodies for the studio, so spending a couple of hundred bucks on a CF card hurts

Ok, call me stupid (and you probably will) as I am NOT by any means someone who has a background in engineering, but would it be at all possible to take the guts of a fast CF with low storage, and combine them with the storage of a higher end CF with slow w/r capabilities?

Yeah, but it's not all that fast.

Newer/fast cards are likely doing something similar internally anyway.

But but but...it says EXTREMELY FAST on the card!

Im really rooting for the development of this on my 5D3, as I just purchased two more 5D3's and cant really afford a 1000x Lexar :-p

I've had to send my Mk3 into Canon for repairs, I'm hoping to death they don't send it back with a block. The camera was restored to 1.1.3 prior to shipping it off, so fingers crossed.

Im sure it's been discussed, but would a CF>SD adapter card, with an SD-USB adapter be an option? Im not sure the transfer speed, but I know I've seen SD-to-USB carts out there. The specific setup I've seen before was SD port>SD-USB>Thumbdrive. It was being used with a PDA, but regardless, I've seen it.

Ok, so this is similar to the product I mentioned in the above quote:
http://www.singaporecorporategifts.com/shop/product_info.php?cPath=137&products_id=1501&osCsid=d67cf03a5260367d452ca02d3d08ac6e

There are no specs listed in terms of speed, but I have sent an inquiry to the manufacturer--hopefully I get a reply. Would something like this be a viable option?

This has been suggested many times.  Apparently, utilizing HDMI is difficult to do and the focus at the moment is to come up with a solution via the CF slot to external HDD or SSD.

I concur that getting a stable release should definitely be the main focus, just curious.

Is the idea on the horizons of developing a proprietary native premiere/aftereffects plugin that would be able to playback the recorded files without any encoding?

I've been testing the raw recording with my 5D3 via HDMI and my SmallHD DP4 LCD monitor.   The main issue I am experiencing (at least when using the SmallHD DP4) is the outline overlay which represents the selected resolution is being displayed at the wrong location. It appears too far to the left and also is placed too high.  Here are the screen captures when I enable Raw Recording...

This one is for 1920 x 1080


This is an example of 1920 x 840.  I enabled crop marks (cinemascope) just to show where the outline should be.


If it is not possible to correct this, may I suggest adding the ability to disable the resolution overlay.  Since this is probably one the more popular monitors out there, I thought I would just let you know this issue exists.

I wasnt able to find the post anywhere, but I remember reading something about getting live preview of the RAW output in the LCD. With this idea, would it be possible to also get a live FEED from the HDMI, utilizing said raw preview? I'm probably misunderstanding this whole thing, regardless...But theres still a slight hope of utilizing the HDMI output to record RAW via xNAMEBRANDx field recorder (such as a Ninja).

I apologize for the lame question. Will this module be available eventually and compatible with the new 1.2.1 Canon firmware. I, unfortunately upgraded and can't find the 1.1.3 firmware.

I have the firmware and can upload it to my DB when I get a chance. But I am also in this situation, and have two 5D3's that are both on 1.2.1...any chance on a port?

[Is the idea of running through the HDMI]

I was about to ask these exact same questions...beat me to it!


Since the last I inquired about recording to the HDMI-out, the developers implied that you did not even thing continuous recording would be possible...but your magical ingenuity has broken through! Is the idea of running through the HDMI's [through an external field monitor such as the Atomos Ninja2] limit of 10gpbs (realistically 3.2) even a feasible approach, or is it completely unrealistic? This would reduce the strain on the camera, and heat would be much less of an issue...

Im going to catch flack for asking this again, but I did not see a response in the pages since posting.

Does Shutter Speed adjustment affect motion blur the same way with the Raw Recordind module? Do you guys think it will be possible to have simultaneous HDMI out and onboard monitor and record raw when ported to 5DMk3 1.2.1 firmware?

6D with new timing:




Buffer size is fairly important. 4MB drop for ~2M

So what does this mean for us non coders(other than more of a reason to eagerly wait a release!)

Dont want to detract too much from the development talk, but I'd like to donate some moolah to the core team--do you guys still have a method for accepting donations? Last I was able, was when we donated for early release of 2.3...

I would hope they can improve it!
I did some testing today of the 5D3 hdmi out and compared to the internal codecs, and the BMCC:

Hard to see what's going on in my tiny iphone5 screen, but what are your impressions on the new firmware?

You mean for 14bit raw?

Basically Canon's HDMI out can't display an image with that much detail.

It's limited to 8bit (which is a huge leap down from 14bit) and HDMI can't display RAW images, it needs to be 'debayered' (reordering the raw pixels into an actual image) and 'sub-sampled' (that means deleting pixels then filling those gaps with clones of the left over pixels) also I think the HDMI spec used in Canon DSLRs don't support anything over 1920x1080 so it would need to be resized or cropped too.

RAW images, are really just a mess of colored pixels until something "debayers" it into the actual image; which is either done in Canon's built in JPEG converter, H.264 converter or LiveView converter (which goes to the HDMI and LCD).

However Canon's built in CR2 converter (for RAW photos) or this added DNG converter (which I think still uses Canon's built in CR2 converter but just sticks it into a DNG container) do not "debayer" so the RAW 'pixel mess' is just saved, the debayer is done (usually automatically) by your computer's picture viewer or image editor.

Awesome, that makes it a world clear! I may be wrong, but the uncompressed clean HDMI output is 8bit 4:2:2@1080...

Would I be wrong in saying that 8bit DNG would still be higher-quality? Yes, it is undoubtedly lesser quality than 14 bit, but this is one of those "take what you can get" situations.

You're saying as if there is Atomos Ninja2 laying in everyone homes.... get a grip Ok? 

There's no need for that. He's only asking because he, like quite a few of us, would find great use with this and it would truly turn our cameras into workhorses, and give BMCC a run for its money...

Because I too was curious about this, but am not a developer by any means, would anyone explain in layman's terms why recording through HMDI out would not be feasible...you know, for us dumb monkeys

I just uploaded 6D... I dunno about anyone else... With FPS override on for some reason the 720P image has more missing pixels on the right... fps override off its perfect 

Just posted a new topic, would love yours or Alex's input.

I'm sure it's been discussed multiple times already, and I will admittedly say I have absolutely zero skills to bring to the table when it comes to actual developmental coding. With this said, the new developments on the silent Raw burst mode are truly a very exciting thing to come, especially for someone such as myself, who is a working unit stills photographer on sets.

In two days (April 30th), we will have clean HDMI output on the 5D3. Pairing this with field recorders such as the groundbreaking Atomos Ninja2 & Samaraui Blade, the 5D3 went up a notch in quality and possibilities. With that on the horizon & the news that ML is working on Raw DNG in burst mode, and my blood pressure escalated with excitement!

Industry figures like Luke Neumann immediately raved about the VIDEO possibilities that this brought to the table, on how we could do 24p RAW on our CF/SD cards...and thats where my skepticism came in.

Sure, our cards can handle burst mode before running into issues, but wouldnt a smarter direction for any future video implantation be with use of field recorders such as the Atomos Ninja2?

I think that should be the direction to take with this, as it is very realistic. There would be no issue with buffer time, and the transfer rate via Cat2 HDMI is "theoretically" something as high as like 10.2gbps, but more realistically 3.4Gbps.

Just some thought...I'd gladly be a guinea pig with my Ninja if someone wants to throw files my way. I've got a pile of 2.5" hard drives I could spare, and a few weeks before my next project starts.

Just a thought, as I'm sure its not nearly as simple as something like this...
