Tragic Lantern / Re: Raw video on 50d and 40d
May 30, 2013, 09:41:00 PM
Quote from: hijodeibn on May 30, 2013, 09:27:24 PMI am still dreaming with 2K RAW on the 50d
Well, stop dreaming. 2K is impossible.

Not because the write speed is to low but because the 50D's maximal resolution is 1592 X 1062 (Without crops). You can't get 20 Megapixel from a 12 Megapixel sensor and you can't get 2K from a 1592 X 1062 LiveView image.

But higher framerates than 24 frames per second might be possible in the future.

Tragic Lantern / Re: Uncompressed 600D Raw Video
May 30, 2013, 03:04:50 PM
I have a question: Could you please add a width between 1120 and 960?

Because with an aspect ratio of 2.35:1 these both will give you 1120 X 476 (21.4 Megabyte/s) and 960 X 408 (15.7 Megabyte/s) and that's a big gap between 21.4 and 15.7 Megabyte/s. Especially because 1120 X 476 stops after ~ 1500 frames, even with hacked mode. Something like 1088 X 448 (2.43:1) would be nice. It would need only 19.5 Megabyte/s and it divides by 64 evenly :D

Or 1088 X 463 for real 2.35:1, if the Y-resolution doesn't matter for write speed. Would that work?

1024 X 436 (17.9 Megabyte/s | 2.35:1 aspect ratio) would be nice too since its X-resolution devides evenly by 64 and 128.

1) The resulting dng I get are not clean when I open them up in ACR (of Cineform Studio) ie. they have a green "tint" (or red - depends on what program I am opening the dng's with). why is that ? I see the everyone here displays a "regular" picture...

2) in ACR, the file says : 8bit (on the info line). shouldn't it be like 14bit ?

3) in ACR, how do you turn on the thumbnail display (to the left) so one can synchronize all the photos ?
1) At the moment the white balance is just a placeholder. The .raw files have no metadata so raw2dng simply adds fake metadata which results in a wrong white balance. But a1ex is thinking about adding the correct metadata.

2) That's just what ACR suggest you to work with. Simply set it to 16-bit and you'll be fine (If you don't use elements).

3) To synchronize all photos just select all of them and then do the changes. Maybe there's a better way, I don't use ACR but LR.

I shoot Raw with my 8/16 GB SanDisk Ultra 30MB/s...
Nothing more than 3 seconds still at 960*540...
Doing the ML test and results that it write at 8MB/s...
How it's possible?
Your card is simply not as good as advertised by the manufacturer. No real surprise, isn't it? They want to sell these things so they make them look better than they are. A quite cheap SD-card that actually has a write speed of more than 21 Megabyte/s:
- SanDisk Extreme 16 GB SDHC Class 10 UHS-1 45MB/s | Amazon.com

I use that myself and it works fine. The 95 MB/s version is said to be good too but ... you know ... 21 Megabyte/s write speed limit ;D

Quote from: Drewton on May 30, 2013, 07:09:15 AMJust did another RAW vs. H.264 comparison, and this is the biggest difference I've seen between the two yet. Exact same lighting conditions and exact same camera settings, but the RAW version is at least 10x better.
Same settings? So you didn't changed the focal length and simply croped the H.264 to match the raw image? If that's true, your comparison is completely useless. To compare H.264 and raw you have to count in the new crop factor you get with raw video! See here:

Width | Cropfactor | Multiple of H.264 crop

1734 = 1.60 | 1
1280 = 2.17 | 1.36
960 = 2.89 | 1.81
720 = 3.85 | 2.41

So if you shoot a video in 1920 X 1080 H.264 at 55mm and you want to compare it with a 960 X 540 raw video you have to change the focal length to 30mm (55 / 1.81 = 30).

Edit: Damn. No I tried to answer that questions and totally forgot what I wanted to ask :D

@1%: Since raw is a dead end on the 600D (Even with 8-bit compression we couldn't record higher than 1280 X 720 :(), what's about recording YUV 422? Is anybody still working on that for the low speed cameras?

I mean, lv_rec still had the option to record YUV 422 "video". It was just to early to be good ... But now, wouldn't it be a nice to make a yuv_rec module for 600D/550D/60D(/6D)?

Raw Video / Re: RAW on 650D / 700D?

600D + 50D sounds like a winner.
600D + 50D = 650D? ;D

(Just a really poor joke ... couldn't resist :D)

Well. Like qsara said: The 650D and 700D should be too slow to handle 1920 X 720 14-bit raw video at 24 frames per second. This would require 55 Megabyte/s write speed, but it doesn't look like these cameras will be able to get that. Especially since the max. LiveView resolution should be 1734 X 1156 like on the 60D/600D/550D ;D

So even if the cards could handle 1920 width, it wouldn't be possible.

At the moment the 50D looks like the best option for "cheap" raw recording. Maybe the 70D will have a CF card slot again. That would be amazing.

Raw Video / Re: 60D RAW video - it's working !!!
May 29, 2013, 03:56:30 PM
The Silent Pictures and raw videos are nothing else than the LiveView image before the Picture Styles are applied. So you can't get higher resolutions than what Canon gives us. For the 18 Megapixel APS-C cameras that means the max. resolution is 1734 X 1156. Only in 5X magnification mode you get a higher resolutions. You could make a high-res matrix be moving the focus box of course.

The 15 Megapixel 50D has an even lower LiveView resolution than the 60D/600D/550D.

A quick question I've asked on the 550d thread but no answer, should we be shooting in video mode or photo mode with 550D and 600d cams, does it make any difference?
It doesn't make any difference in picture quality and it should make no difference in performance. But in photo mode you can't set ISO, aperture and shutter speed manually. Sure, you can change the numbers but the actual aperture doesn't move if you change the number on the display.

So: For manual exposure control, record in Movie Mode.

Quote from: y3llow on May 29, 2013, 12:01:07 PM
Could someone clarify then this sRAW, is this the difference between line skipped video mode vs 1:1 crop photo mode?
There's a feature in the newest Magic Lantern builds that allows you to change the picture quality for photos inside the Magic Lantern menu.
Usually this is only possible in Canon menu. You know, that are the settings like "L" (For Large JPEGs) or "RAW+L" (For Large JPEGs and Canon raw pictures).
And since the Rebel line had only one size for raw pictures, ML added two more sizes: MRAW and SRAW (Medium and Small). They don't work properly but they affect the size of the buffer. And that's the important thing: The normal size of the buffer is 68 Megabyte. With MRAW it's only 36 Megabyte but with SRAW it becomes 96 Megabyte. And with a bigger buffer you can record more frames, even in higher resolutions.

SRAW has nothing to do with crop modes. And it doesn't affect the image quality of the raw videos. It only increases the size of the buffer.

But when SRAW doesn't work on your cameras then 1% probably was right when he said that the 550D is actually the worst camera for raw video. But don't worry, 600D is the second worst :P

And keep in mind that when shooting in Canon's 720p mode you'll get even more aliasing than in 1080p or 480p mode since it has even more line skipping. It's only usefull if you want to get as much width as possible to keep the crop factor small.

Hopefully the 10bit hack will help us get closer to full hd. We can only wish.
Sorry but even 10-bit won't solve the 21 Megabyte/s write speed issue. It should allow us to record 1280 X 550. That's a nice 21:9 aspect ratio.
(1280 X 550 X 10 / 8 X 24 = 20 Megabye/s)

And once you 550D guys get the "SRAW" option back, you'll get at least continuous recording in 960 X 540 :D

Quote from: apefos on May 28, 2013, 09:32:35 PMmy malloc total is 96M, can I increase it someway?
What do you think setting "Pic Quality" to "SRAW" has done? It should have been 68 Megabyte and by changing the "Pic Quality" setting and rebooting the camera you've already increased it. If you want to get even more, just use one of the old builds where we had 104 Megabyte.

But obviously you'll have to sacrifice some of the new features.

Well. I'm glad I could help. Hopefully 1% can concentrate on more important things than adding these uselss 8XX width resolutions ;D

@ 1%: Since I wanted to learn C++ anyway I'll see if I can start with it this weekend and help you improving this awesome firmware addon some day :)

@ apefos: I think you're doing something wrong.

Like I said: I can record ~ 2000 frames in 960 X 540 without any skips and about 40 magenta frames. With Edmac Popin build I could reach the 4 GB limit (Which is no real limit. I just don't use exFat). If you can't get that, your settings are wrong or your 600D is just worse than mine.

How big is your buffer? ("Debug" tab - Hit "Q" on "Free Memory" - "shoot_malloc total" is what you're looking for.)
Are you sure that you've rebooted your camera after you set "Pic Quality" to "SRAW"? And are you sure that you don't record sound?

May 28, 2013, 08:13:47 PM
True ... The 550D guys don't even have the option for "SRAW" :)

(I think somebody should try to give it back to them. They are really screwed with their 68 Megabyte shoot_malloc, aren't hey?)

I'm curious: I have no skills in any programming language other than Java and PHP/HTML. But is this actually important? From what I'm reading here I've got the impression that everybody who has an idea of some technical stuff can help with porting and improving Magic Lantern (And I mean not just by testing your amazing work ;D). Is that correct?

(If not, which language(s) are required?)

But at least the 6D has no 21 Megabyte/s write speed limit ;)

I'm still hoping to get at least the 104 Megabyte buffer size back and maybe even some lossy compression ... But I know that the 600D is by far one of the worst cameras for raw video.

Poor 1100D guys. I bet they have something like a 10 Megabyte/s write speed limit and 50 Megabyte shoot_malloc ;D

We can't even close to compete with 50D/5D2 and even 60D.. they all have close to 200MB.
With its optimal "Pic Quality" setting (Like "SRAW" on the 600D) the 50D has 220 Megabyte shoot_malloc total and the 60D has even 276 Megabyte! At least that's what I've read.

@ Luiz Roberto dos Santos:

1) Make sure that your file structure looks like this:

- SD-Card
---- ML
------ MODULES
---------- MAGIC.SYM
---------- raw_rec.mo

2) Set "Pic Quality" to "SRAW" and reboot your camera. After that you should be able to record longer in 960 X 540.

3) If you want to bypass the 4 Gigabyte files size limit, format your SD-card as exFat in Windows. Then use EOScard to make it bootable again.

And for those of you that are still getting magenta frames: You're doing something wrong. I've recorded 1000 frames in 960 X 540 and only 24 of them were magenta. In my opinion that's totally acceptable. And that was even with LiveView ...

Btw. @ 1%: Is there a way to get our 104 Megabyte shoot_malloc back? Edmac Popin was much better than the current build in terms of what was possible. I think it had the best performence until now ... :D

anyone tried the lv_rec module? what does that do?
lv_rec was the predecessor of the current raw_rec module.

It wasn't really great. If even the much faster raw_rec doesn't work properly on the 550D then lv_rec will be completely useless ;)

And lv_rec was mainly for recording 422 video, not raw.

You can bypass the 4GB limit if you format your SD card as exFat.

Many thanks ! Unfortunately this menu item is not present in ML on 550D, full version (not the ripped-one for raw video).
Perhaps it's a feature useable only on 600D and other models, or it's simply not enabled on 550D... do some experienced developer can shed light on this ? Many thanks !!
I don't know if this feature should be available on the 550D ...

It wasn't supposed to change the buffer size but to allow taking raw stills with low resolutions.
I accidently found out that it has an affect on the size of shoot_malloc - The buffer that is used to store the raw frames :D

As far as I know some of the more expensive cameras like the 7D have this feature even without ML. So maybe it's just for the 600D at the moment ...

Well, I searched a little bit in the Magic Lantern forum and found some interesting quotes:

Quote from: a1ex on July 29, 2012, 11:28:14 AM
I'd rather try this kind of experiments on 60D in C mode, where settings are not saved to ROM. But the 60D already has MRAW/SRAW... [...] You can save MRAW/SRAW from 550D, but nobody was able to develop these files. [...] On 550D, the user interface gets corrupted when enabling MRAW/SRAW. [...] Be careful: setting one property may cause other properties to be changed.
Quote from: 1% on July 31, 2012, 07:06:05 PM
Is it still in the code? Maybe I can try it again?
(Source: 10mp raw picture option for xxxD's)

To me it looks like 1% had some kind of success. The raw images I get in SRAW and MRAW actually are smaller ... Although they still won't open in Lightroom.
But what's more exciting about this is that it did exactly what a1ex suspected. It changed one other propertie: The shoot_malloc size!

But maybe a1ex disabled it for the 550D since it's seems to be very buggy and it didn't work anyway? I think you should ask a developer to renable it.

Btw. here is how it should look like: Shoot tab on 600D
#121
Quote from: dlrpgmsvc on May 26, 2013, 12:35:33 PM
Where is to set this "SRAW" parameter ? Canon or ML ? And where ? Many thanks !
On my EOS 600D it's only in the Magic Lantern menu. It's in the "Shoot" tab. The setting is labeled "Pic Quality". Setting it to "SRAW" does the trick for the 600D. But you have to reboot the camera to see the effect.

But maybe it's one of the functions of ML that are disabled at the moment? If that's true, then it should be renabled. It's all about buffer size and write speed. And even a couple Megabyte more buffer will make a huge difference in how much frames you can get.

Since every camera seems to have a "Pic Quality" setting that increases the buffer size (e.g. "SRAW" for 600D = 30 MB more, "JPEG" for 60D = 94 MB more), the 550D should have one too. You just have to find it and I'm sure you'll get almost the same performence as the 600D.
