Canon's SD-card interface in 5D3 is limited to about 21 MByte/s in movie mode. If you are able to record to SD with higher data rates feel free to edit this chart.
As time of writing CompactFlash is the only way to record high resolution with decent duration.

Hi evetyone, i was checking the [ML] Canon EOS Features Comparison chart, and i was wondering why the Max Continuos recording at 24 and 30fps of the 6D are not updated. On the nightly build i am using, this are the stats. They work fine, so far.

6D MAX Res 30fps Continuos recording:

4:3 = 960x720
16:9 = 1152x648
2.35:1 = 1344x572

6D MAX Res 24fps Continuos recording:

4:3 = 960x720
16:9 = 1280x720
2.35:1 = 1504x640

I'm surprised the 50D low-light performance is listed as "average" with its larger pixels. I know pixel size isn't everything, but I would consider it at least "good." I guess that's just kind of a subjective thing though.

Also wouldn't the 700D have the same resolutions as the 650D? Same SD slot speed, same sensor size...

Last thing - wouldn't it be helpful to have a max continuous 24fps resolution in "squashed" mode (where you stretch by 1.4x vertically in post)?

extremelypoorfilmaker: I think the main problem with that chart (which we can all edit, except we can't), is that most development on Magic Lantern seems to have haltered. I've used a 6D in conjunction with a 5DmkII, and they both performed identically, FPS and resolution wise. 1728x768, both continuous, no problems. (Aspect ratio 2.25:1)

The thing now is I'm debating whether or not I should get a 6D or 5DmkIII, and the lack of updates isn't helping, per se. (cost is the main issue here, I'm well aware how the cameras perform otherwise)

Walter Schulz · « **Reply #229 on:** February 11, 2015, 06:47:10 PM »

Please provide proof that you are able to do RAW/MLV with 1728 x 768 in 24 fps continuous with 6D.

extremelypoorfilmaker · « **Reply #230 on:** February 11, 2015, 07:25:13 PM »

I am currently using this version: magiclantern-Nightly.2014Aug20.6D113 on my 6D

On this version, the aspect ratio you mentioned: 2.25:1 is not present. It's 2.20:1
when i say continuos recording, i imply that no frames are skipped. I quickly did a test at the resolution you mentioned and yes, by skipping frames "continuos recording" is possible.
I don't regard skipping frames as continuoos recording, and the SD card i am using is a Sandisk Extreme pro 32gb.

What version of ML are you using, tomellingsen?
Many thanks

tomellingsen · « **Reply #231 on:** February 19, 2015, 06:45:55 PM »

I actually tried it just now, as I just got a new 6D. The one we were shooting with this summer didn't capture sound, that might be why it was able to do it. Right now, the math doesn't add up. I've tried 1728x768 with 2.20:1, and I got about 15 seconds before it started skipping, using a Sandisk 32GB Extreme card, so yeah, you might be right.

I'm also unsure of the version that camera was running. It wasn't able to capture sound at the time, so it might have been one of the builds before that, or the module wasn't loaded.

extremelypoorfilmaker · « **Reply #232 on:** February 20, 2015, 07:50:17 PM »

On my canon 6D and the latest build, still, sound or no sound, continuoos recording is possible only in the specs i have listed above.. In all honesty, i really wish it was possible to record continuosly at the resoultion you stated!

ah, one last thing, to answer your question about what camera get: 5D3. Is a no-brainer. I am saving up untill i have enough to get one, the 5D3 IS the magic lantern camera. Hands down

Hi,

According to the chart the 600d can capture RAW 14bit with no crop at 1728x1156 at 1:1 liveview.
I have tried to change the settings to attain this resolution, but have failed. I have been able to record continuous (over 7 min) on 960x540 24fps 16:9 but the frame is very cropped. I want to minimized the cropping as much as possible, preferably null.

My interest is to capture at 16:9 or in worse case 2.39:1 at 24 fps.
What should I change on both the canon menu and on ML menu in order to be able to capture 1728x1156.

Thanks in advance.

1728x1156 at 1:1 liveview. I have tried to change the settings to attain this resolution, but have failed.

Which resolutions do you have for 1:1 liveview with RAW_REC.mo and/or MLV_REC.mo?

ibrahim · « **Reply #235 on:** March 02, 2015, 12:34:06 PM »

With MLV_REC.mo for 1:1 liveview (at 24fps) I have the resolution 704x704 as the only stable (under 21-22 MB/s), which is at 19.8 MB/s.

Walter Schulz · « **Reply #236 on:** March 02, 2015, 12:45:45 PM »

Sorry, but which question do you want to ask?

- Which is the highest resolution (if non-crop is used) available for continuous recording?
- Which is the highest resolution available if non-crop is used? Nope, not interested in continuous recording
- Which is the highest resolution for a squared frame in non-crop mode?

Let's define "non-crop" = without electronic 3x zoom

ibrahim · « **Reply #237 on:** March 02, 2015, 01:22:47 PM »

My question concerns how to record at resolution 1728x1156 as the chart states. The chart shows a blue color (signifying that it is stable). In other words, what should my options on (mL menu and canon menu) should be set at to record such a high resolution.
It states that the resolution 1728x1156 can be shot at 1:1 liveview, resulting in no crop.

From what I understand with the term no-crop, I want to shot the entire frame that I am looking at during shooting on my canon's LCD. I only get a portion of it whether I shoot at 16:9 or in 2.39:1.

Walter Schulz · « **Reply #238 on:** March 02, 2015, 01:28:52 PM »

Yes, it states 1728x1156 is possible but it also states that cam's write speed is limited to about 21 MByte/s so you can't have it for continuous recording.
1728x1156@24 continuous would require an interface with about 80 MByte/s. Numbers don't match -> Go for lower resolutions for continuous recording or shorter durations with higher resolutions.

ibrahim · « **Reply #239 on:** March 02, 2015, 01:42:41 PM »

Ok thanks.

So there is no setting on ML that results in capturing the entire frame?

Walter Schulz · « **Reply #240 on:** March 02, 2015, 02:01:23 PM »

Of course there is: 1728x1156.

It is not working. Shooting at this resolution results also in a very cropped frame. Why is it so?

Walter Schulz · « **Reply #242 on:** March 02, 2015, 02:21:18 PM »

Back to square one:

What are you trying to do?
You can shoot in 1728x1156 but only for a very limited time or with very low fps.
You can do continuous recording in lower resolutions but this will result in a cropped view. It will be a frame inside Liveview's 1728x1156 frame.
Look at the numbers ML will tell you (text at bottom) if you select horizontal resolution and aspect ratio for any given fps.

ibrahim · « **Reply #243 on:** March 02, 2015, 09:08:59 PM »

Ok, thanks. So I need to shrink my fps to say 10 or even lower to be able to record at higher or closer resolutions to 1728x1156. I can record at 1728x1156 continously if my fps is set at 5. I've tested it. Too bad that 600d's write speed limits ML performance despite the expensive cards I use. This brings med to next question that concerns using ML on 5D mark III, which I intend to purchase.

If I shoot at 24fps 1080p (continuous) it would not result in a cropped view (instead result in capturing the entire frame inside liveview's 1080p)?

In order to shoot continuous at 1080p on the 5dIII what's the minimal write speed required by my card/camera. I intend to use my card with the following specification on a 5DIII:
SanDisk extreme pro SDXC I 95MB/s 64GB class 10.

Walter Schulz · « **Reply #244 on:** March 02, 2015, 09:29:02 PM »

Sorry, but 5D3's SD-card interface is limited to 21 MByte/s, too.
You need the fastest CF-cards available to record 1080p24 continuously.

DeafEyeJedi · « **Reply #245 on:** March 03, 2015, 05:38:09 AM »

@ibrahim:

If budget limits you for a decent fast CF...

Look into KB 32GB 1066x

Or go for the KB 64GB 1066x if you want to record longer takes.

I'm happy with my KB 128GB 1066x so far...

budafilms · « **Reply #246 on:** March 07, 2015, 07:00:57 AM »

@ibrahim
try the Komputerbay 64 GB 1000x, I have a couple, are very cheap and works perfect for full HD.

Thanks for the advice.
Do you use it on 5DIII?

DeafEyeJedi · « **Reply #248 on:** March 23, 2015, 09:48:45 PM »

Correct and works really well.

ibrahim · « **Reply #249 on:** March 23, 2015, 10:03:34 PM »

Great. Do you then manage to capture the whole frame inside Liveview's 1080p frame or only a portion of it? Because most DLSRs only capture a portion of what is seen on canon Liveview.

Knowing that the speed of such CF card is around 150-160 MB/s, what is the highest resolution possible at 24fps and at 60fps, respectively?
