Is it possible to have RAW video recording abilities on 550D?

[prabhath.mp]

Hi All,

I recently got to know that Canon 5D Mark III can record DNG videos (RAW videos).

Could anyone please let me know if 550D hardware is capable of recording DNG videos. I understand that the resolution might not be anywhere close to 4K (assuming it might however be able to capture at least 2.5 K?) however the quality of images might get better with DNG as it gives us complete control over picture to grade in post production.

Thanks for answering

+1, I associate to this question, and waiting for answer ! It is a great achievement 24fps 1080p RAW, but on a 5DMKiii ... a camera that only the body costs up as a leg and an eye... everyone is near to buy, instead, a natively raw-enabled video-cam ! The real achievement, the real breakthrough, the real bargain, the real stunning, the real amazing, the real useful, the real thing... is to port all this to a camera like 550D !

550D is so old at the moment... yes the stuff will port but don't expect much. 600D is already ported.

Hi,

Thank you for answering & adding your thoughts

Since the possibility of any budget conscious user thinking about upgrading the camera to 600D or above is not very feasible, would it be possible to have the 550D ported instead?

It would certainly open a new horizon for many short-movie makers around the world.

Also, regarding the resolution, what could we expect as I am not sure if 2.5 K is possible (was hoping that it might however)

Thanks once again!

Cheers..

"stop working on 600D and work on 550D instead"... what?!

Run the card benchmarks and we'll tell you what resolution you can get. Probably 800x600 or so.

[1%]

Lol, probably 800x480 or 400 and fio write file on this camera can do > 4gb? Exfat didn't even exist?

[a1ex]

I wonder what we can get from 500D, that one is really interesting for studying the history of Canon's LiveView. The only camera with 20fps video, hehe

[1%]

Actually interesting because it may have less things running... Just wonder how much memory it has.

[N/A]

Yeah if you guys can't even get raw video enabled on the Canon EOS 650, the whole thing's a bust.

[a1ex]

50D might also be a good option, since it uses CF cards. Anyone ran benchmarks on it?

[ecek2]

[a1ex]

At 14MB/s... you can hope for 720x480

what about 4K 1fps RAW with manual shutter speed ?

Fellow 550D user here, thought I'd run and add my benchmark results.






Having followed the recent developments I'm keen to see what could be possible with the 550D, should a port be forthcoming. How much further would a 95MB/s card push the possibilities? Or is the 550D itself going to be the limiting factor here?

Whatever, many thanks to all the guys at Magic Lantern for what you've achieved, thus far!

I was going to buy a 95MB/s card to see what 550D could spit out. But on your benchmark of a 45MB/s card it couldn't even reach half that. In fact, I  got near same results on a class 6 card.


On a different note, what is better;
4:2:0 at 1920x1080
or
4:4:4 at 960x540

Hi All,

Thank you for your feedback/thoughts.

I am not familiar with technical aspects of these cameras.

I only thought that if a camera has video capturing ability and also has the ability to capture RAW (CR2) images, then it might as well be possible to port them to capture RAW video!

I am not quite sure about the probability however as I am only an end user. Could anyone let me know if this is possible?

Also, does 720X480 mean that the resolution is no where close to 1920X1080 or does it affect the quality if we digitally manipulate the resolution during video processing workflow. I did not understand this concept.

I use a 16GB 30MB/s Class 10 card. How much resolution can I expect (if it would be possible to capture RAW/DNG video). As we would be capturing DNGs I believe we would not be able to record voice (please correct me if I am wrong). Or is that too possible?

Thanks for answering

Cheers..

I have ML running on my EOS 650 just fine

Hi,

Does the same firmware/upgrade work for Canon EOS 550D too?

How do I perform a benchmark test as discussed by fellow users here? I have never tried that procedure until now

Also, please help me understand whether memory card plays a crucial role or whether it is with the hardware of the camera that determines whether it can capture RAW video

Thank you for all your help/feedback/support.

Cheers..

We can totally get raw on the EOS 650... just spin the film real fast... its the rawest raw that ever existed.

[wolf]

It looks like a waste of time trying to get RAW video on a 550D.
But there are breathtaking "non RAW 550D videos" out there. :-)

My hope is silent pics will be possible one day with a better resolution.

[dlrpgmsvc]

Even at SD resolution, it's not a waste of time... on the contrary !

Fun fact. The 5d Mkiii was announced on the 25th anniversary of the Eos 650.

I smell a conspiracy theory coming in 3... 2....

AGREE!!! 100% 14bit RAW Video is what matters even at SD.

[tin2tin]

Another question could be if the YUV conversion could be surpassed and then saved as compressed RGB in mov(or some other/better codec)? Wouldn't that give a wider color range? I mean on cameras with SD cards only.

[ecek2]

I believe that Alex has 550D.
So, I think he will work on it when he have time.

[a1ex]

Yes, I still have the 550D. But right now, the 5D3 and 5D2 have the biggest potential for raw video, so I'll focus on these for now. I've posted a porting guide for DNG silent pics here: http://www.magiclantern.fm/forum/index.php?topic=5240.msg32128#msg32128

For old cameras, there is some hope with MJPEG. See http://www.magiclantern.fm/forum/index.php?topic=2803.0 for some research in this direction.

Sample still frame (5D2, 1:1 crop):



Sample video: crop.avi
H.264 video (same lens, settings, subject distance): noncrop.mov

Problem: these jpegs are quite small and we can't change the resolution. But they seem to be 422 (from pixel peeping).

These JPEGs are even available in the ancient 40D (1024 x 680). I know they are in 5D2, 7D, 550D, maybe 60D. I wasn't able to enable them in 5D3.

Yesterday i run a benchmark test with a Transcend Premium (16GB-20MB/s), Transcend Ultimate (16GB-90MB/s) and a noname Card (8GB) on my 550D.
All 3 Cards had a writing benchmark around 15 - 21 MB/s, regardless of Globaldraw on/off etc..

Either the 550D is the limiting factor or i'm just too stupid to handle my SD-Cards 

[-sandro-]

I own the 550D and if the SD controller is the bottleneck I don't see the point of even trying to get RAW video...it's better they concentrate on more capable cameras (maybe the newer 650D) sell and upgrade to those.

Nice job!

Alex does it make a difference having newer digic processors for RAW video?

[1%]

In all honesty, 650D I think has less memory. 550D as worth it as anything else depending on how much memory is available. Someone with 550D had to do the legwork which it seems like they are starting to.

[-sandro-]

I see...well I meant to develop something for APS-C sensors since not everyone is interested in spending many $ks for full frame. Is here a new  APC-S camera with CF card support?

BTW do we have access to HDMI yet via ML? Maybe transfer the RAW video through it...imagine what it would happen A revolution

[dlrpgmsvc]

Just some think-tanks ...

5D3 is most promising for raw video... sure... but what's the point to squeeze out raw 1080p video (with so much efforts and sacrifices) from a camera that costs the same like a blackmagic, where blackmagic has a hassle-free (no single images to process one-by-one) 4K raw ? How many people will buy a 5D3 instead of a bcc for exclusive video purposes ?

5D3 is most promising for raw video... sure... but what's the point into pushing all the forces exclusively on this direction, when you can clearly see the results of the poll "what camera you have?" here in this forum, but neverthless it is continuously said "550d is too old...", "550d is not worth the efforts..." ... and so on ?

Sure, 5D3 is the main benchwork to concentrate on, in order then to port to the rest of the models. That's the right way.
Sure, 5D3 has a larger sensor so more light sensitivity than a bcc (not so much more, however). But as an advice: don't understimate the impact of even a SD resolution raw video achievement on the "poor" 550d !

Hi Alex & fellow ML users/developers,

Thank you for all your inputs/suggestions here.

I honestly thank you all for your efforts in bringing out the hidden features from Canon Cameras to make best use of them.

I believe 550D could somehow be a good competitor to the BlackMagic pocket video camera (just hoping, not very certain).

Could you please let me know which card would be optimum to achieve RAW video recording (when it is made possible on 550D)?

I have a 16GB 30MB/s class 10 card. Please advice if I have to buy a better card for this (please provide specifics)

Also, is there a different version of ML for recording RAW videos (silent picture). If the firmware (RAW video on 550D) is already existing, how many FPS could be achieved as of now?

I am not very familiar with this and I appreciate your help in this regard.

Cheers,
Prabhath MP

With cameras older than the 650D that do not have a CF slot all you can hope for is RAW video at SD resolution. I would buy a class 10 card but the one you have should be ok too (the controller on the 550D maxes out at around 20MB/s)

[1%]

Cheap C10 card is a bad idea... even tho its only 20MB/s the cards aren't going to keep it up. From doing BR on 600D you want something UHS that works really well at the lower mhz.

You can also burst for 100 or whatever frames at the higher resolutions... this may be enough for some people.. and shoot maxed up H264 for the rest.

Also for these slow ass cameras we should make a cropping YUV recorder. At least it would be 4:2:2

Still, the quality of SD RAW video would be far more better as it would give us more dynamic range

Just a thought:-

• It would help beginners to experience and learn dynamic range (I'm not sure how much range we get on SD card whether 14 or 12 or less) which is essential for anyone interested in understanding colours.
  
  In most scenarios we will not have control over the recorded video (or if we did have it would be very minimum)

Any suggestions on this would be helpful

[ashtrai]

Even though it might seem futile to developers, 960x500 raw 14bit video would be better than the 1080p h264 default video we get from Canon. My guess is that the raw video upscaled 1.33x to 720p or 2x to 1080p would hold up pretty well, and the extra color information would make the images a lot more clean and pleasing than the h264 counterpart.

[internetjoke]

This would be really cool.

Hi,

I've got a 550D and i'm wondering, it's not possible to change the sd reader/writer inside with something faster ? Or it's the chipset which is slow ?

I know talking about hardware is quite different from software, but if it was possible to buy a SD reader/writer faster for "old" Canon, that would be great, Magic Lantern could sell it and make a little money to support their work.

Thanks.

Mikaël

Hi All,

I did not get an answer to my query in the quoted forum. Could anyone please reply to that?

I am still in the process of learning and your advice is very much appreciated.

This query might have been already answered however could anyone please let me know how safe is the new update (for recording RAW on 550D) http://www.mediafire.com/download/37ag5vd6z7mm4vj/ML_Raw_fps_ETTR.rar - Has there been any update after this?

Can I use this on a 16GB Sandisk 30MB/s Class 10 card to record RAW?

Also, has anyone tried to copy these files from an Ubuntu operating system (13.04)? (I previously had Windows XP when I had copied version 2.3 to the SD card). Is the procedure still the same or would there be any compilation errors if I copy from any other operating system except Windows?

If I just format the SD card on camera and then copy paste the ML folder and Autoexe.bin file does it work as it should?

Sorry for asking too many questions but I am eager to know

Thanks for answering!

Cheers..
