Tragic Lantern / Re: 50D and 40D Raw video
« on: October 07, 2013, 02:22:54 PM »
as for a pixel having value of 0 to 255, instead of 16384.  I'm talking about before de-bayering which is what the camera records to RAW in, either red, green or blue values.
I think you've got that wrong. The Canon DSLR record the uncompressed bayer data from the sensor which has a color depth of 14 bit per pixel. Since it's bayer data, you get 50% green, 25% red and 25% blue pixels and each of them has a value of 0 to 16383, even before the debayering. That's also the reason why a raw video with a reslution of 1728 X 972 at 24 frames per second wouldn't be 40 Megabyte/s but 70 Megabyte/s.

This looks really good. Much better than these versions with more than 11 Boxes. I love it.

I love that design and I think a histobar would be really nice!

Please implement it, if it's possible and not to much work. :D

Tragic Lantern / Re: Uncompressed 600D Raw Video
« on: September 05, 2013, 09:39:13 PM »
Yes, same thing here. 107 Megabyte buffer with the current Nightly and the 'Pic Quality' still set to 'SRAW'.
But when I replaced the Nightly's 'autoexec.bin' with the 'autoexec.bin' from the Tragic Lantern 'SixThirty' build it was 103 Megabytes again.

Maybe there's even more space left ... Or is it a bug?

By the way, which raw_rec version is the best? The 'SixThirty' version or the version from the current nightly build?
Or is there a version I'm not aware of because 1% had to upload it somewhere else again?

Raw Video / Re: Raw 600D (T3i)
« on: September 03, 2013, 09:37:37 PM »
Well, use Tragic Lantern :)

Even if you don't want RAW, it helps to improve the 600D's quality. At least it used to. The newer builds don't have these features anymore :(
(@ 1% do you already know when the GOP & slice control will come back? :D)

Pink frames seem to appear if the buffer fills up too fast.

If you use resolutions above 0.5 Megapixel the buffer fills up faster than the camera can write stuff to the SD-Card. So you'll probably get pink frames even with Tragic Lantern. If you increase the size of your RAW buffer (shoot_malloc) you can film at higher resolutions without getting pink frames. At least it works like this with my 600D and the current Tragic Lantern build. I usually shoot at 1280 X 512 (0.65 Megapixel | 1:2.5 aspect ratio) with 24 frames per second (27.5 Megabyte/s write speed required). With 'SRAW' I can film for slightly above 10 seconds and get 0 pink frames.

But if you don't want to use 'SRAW' and really need to use resolutions above 0.5 Megapixel, decreasing the framerate might be the only way to avoid pink frames.

Raw Video / Re: Raw 600D (T3i)
« on: September 03, 2013, 09:16:34 PM »
My card will do 95 MB's.
That is right. But the 600D's SD-Controller doesn't support UHS-I. That means it can't write faster than 21.5 Megabyte per second. Even if your card was as fast as a SSD it would be useless. The camera is the bottleneck. It is completely pointless to use such a fast card as yours with this camera.

And that's also the reason why you can't get continous recordings with resolutions above 0.5 Megapixel. 0.5 Megapixel with an aspect ratio of 16:9 equals 960 X 540. So that's the default for the 600D and the only resolution that you should use for continous recordings (At 24 frames per second! Lower framerates allow higher resolutions).

And the 'SRAW' option may be called unsafe since it can't be changed from the Canon menu. That's basically it. Usually you need Magic Lantern to change the 'Pic Quality' setting back from 'SRAW'. But you can simply reset the camera in the Canon menu. That works too.

@ dslrrookie: You probably get pink frames because your buffer is too small. Use 'SRAW' to increase the shoot_malloc buffer and reduce the amount of pink frames or reduce the framerate if you need the higher resolutions. That should help.

Tragic Lantern / Re: Uncompressed 600D Raw Video
« on: September 02, 2013, 01:44:28 PM »
Could you please tell more about this? I've searched the last few pages of dual-iso thread, but can't find much info about 600D. What's available? Only photo, or video too? What are the drawbacks (there must be some because 600D isn't as good as 5dmk3, right?), etc...
I tried the feature on the same day 1% released it some weeks ago. It works in LiveView, Photo Mode and even with videos if you film in RAW.

It's a great feature and increases the dynamic range by up to 3 steps thanks to the 600D's native ISO 3200.
There are no limitations on the 600D, it is as good as the 5D Mark III. Well, since the RAW videos of the 600D have really low resolutions using Dual-ISO with videos will probably give you many artefacts. I tried it only two times and the result looked very bad. But A1ex made much progress since that day and maybe he could improve the quality ...

I would have to try it with one of the newer CR2HDR and RAW2DNG versions.

You need a SD-Card reader to get the .RAW files from the card.

Tragic Lantern / Re: Best settings for raw / 600D - TL2.0
« on: August 20, 2013, 05:57:21 PM »
I tried using sraw and didn't make a difference as far as # of frames recorded.
Very strange. Are you really sure that you've set the 'Pic Quality' to 'SRAW' (Without anything else) and then rebooted your camera?
If you don't reboot it, 'SRAW' doesnt work. Maybe you forgot that?

It makes a huge difference in terms of how many frames you can get, if you use 'SRAW' since it increases the shoot_malloc buffer by 30 Megabytes. And it is the only real benefit of using a Tragic Lantern 2.0 build instead of the normal Nightly Build version.

With the 'Pic Quality' set to 'RAW' I get between 180 and 240 frames at 1280 X 544 (2.35:1) 24p and with it set to 'SRAW' I get 270 to 330 frames. I would call that a difference, so I guess you made a mistake somewhere ;)

Another tip for slightly increasing the amount of frames: Set the resolution in the Canon menu to 640 instead of 1920.
That reduces the size of the YUV buffer a bit and leaves more space for Magic Lantern stuff. But it helps only a little bit.
Using 'SRAW' is the most important setting for "long" recordings at higher resolutions.

By the way, why are you using ISO 1250? What does that have to do with the performence?

Raw Video / Re: 550D raw video recording port official thread
« on: August 19, 2013, 05:37:10 PM »
Here is some RAW video tests I threw together
No offense but this comparison video seems quite pointless ;D

I mean, it is supposed to show ... what exactly? In this test, it looks like the squished 1280 X 388 RAW videos would be better than regular 1920 X 1080 H.264 videos in terms of sharpness and detail. And that's just not the the case. Why did you downscale the H.264 footage? And why did you bulred it so hard? Why is the field of view so different in many shots? Did you crop the video, or did you actually changed the focal length?

I don't want to say that the comparison is horrible. But you should tell us exactly what we are seeing and what it is supposed to show.
That would make the video more interesting and helpfull.

By the way, if you film in the squished 720p mode, be carefull. It can give way worse aliasing than the unquished modes.
I would use it only if I needed a really shallow depth of field.

Raw Video / Re: bayer pattern in crop vs non-crop raw video
« on: August 14, 2013, 08:53:43 PM »
As a 600D user I am really interested in the best way to upscale your footage too ;D

My footage has a way lower resolutions than yours but so far I got really nice results using a simple AviSynth script.
(Here it is:   [Spoiler]LoadPlugin(ScriptDir()+"..\Avisynth-plugins\nnedi3.dll")
# Get the Plugin here: http://web.missouri.edu/~kes25c/nnedi3.zip
# Edit the path if necessary

LoadVirtualDubPlugin(ScriptDir()+"..\VirtualDub\plugins\msu_sharpen.vdf", "MSUSmartSharpen", 0)
# Get the Plugin here: http://www.compression.ru/video/smart_sharpen/src/smart_sharpen.zip
# Edit the path if necessary

ImageSource("PATH TO YOU TIFF FILES\%d.tif", FIRST_FRAME'S_NAME, LAST_FRAME'S_NAME, FRAME_RATE, false, false, "RGB24")
# That works only if your TIFF files are named like this: 1, 2, 3, 4, [...], 678

nnedi3_rpow2(rfactor = 4)

ConvertToRGB32()

MSUSmartSharpen(3)

ConvertToRGB24()

Spline36Resize(1920, 768)
# If your aspect ratio isn't 2.5:1 you may want to change the second number ;)
# If you want 4K, use 4096 X (4048 / YOUR_ASPECT_RATIO)
[/Spoiler]  )

If I would be better in scripting, I guess I could do what Hendrik suggested with AviSynth.
But I suck at scripting. There are some AviSynth Pros out there. Maybe one of them could do it. I don't know.

If you don't know AviSynth: It is a really powerful editing software. But it has no front end. So instead of using an interface you have to write a script and run that script inside another editing software. The tool that was used to process the old HDR videos based on AviSynth.

If you find the best way to upscale RAW videos, please share it with us :D

Raw Video / Re: bayer pattern in crop vs non-crop raw video
« on: August 14, 2013, 06:37:22 PM »
As far as I know, the sensor looks like this:

- Sensor Pattern

And with line skipping it simply reads every third line and every third column, so it looks like this:

- Line Skipping Pattern

So the debayering method is the same. The pattern is always R G R G for the uneven lines and G B G B for the even lines.
(R = red | B = blue | G = green)

But if the debayering algorithm is too bad, the images with line skipping may look bad too because of the big gaps between the pixels.
But I would like to know how the skipping works in 720p mode. There it reads every third column but only every forth line ...
And of course it would be cool if Magic Lantern could set the skipping ...

1% got Dual-ISO working on the 600D. For stills it is really nice.

The 550D will probably have Dual-ISO since it has the same sensor :D

Modules Development / Re: Dual ISO - massive dynamic range improvement
« on: August 13, 2013, 07:58:35 PM »
600D, its not perfect. I saw some artifacts.

http://www.filedropper.com/600ddualiso
I just tried it on my 600D and it works fine! Just amazing!

It's so impressive to see how much progress has been made in the last time. Such insane stuff.
First 14-Bit RAW video and now almost 3 steps more dynamic range! What's next? :o
This really is MAGIC!

Thank you very much for posting this build. It is freaking awesome that Magic Lantern gets developed since 2009 and still it looks like the biggest treasures inside the cameras aren't even found yet. Who would have thought that any DSLR can handle RAW video? Even 2K RAW video! Or that a Canon camera could get the dynamic range of a Nikon sensor?

I am really curious to see how this firmware add-on will change in the future. It is by far the coolest thing you can download from the internet.

Modules Development / Re: Magic Lantern (RAW) Video format v2.0
« on: August 12, 2013, 09:42:28 PM »
Well if anything the 5D Mark II should be better than the 50D. They were released at the same time, except the 5D2 was around 2000 dollars more.
The 5D Mark III has the same SD-Controller like the 600D. Why do you think the 5D Mark II should have a different CF-Card than the 50D?
Canon uses the same components for multiple cameras to keep the prices low.

Modules Development / Re: Magic Lantern (RAW) Video format v2.0
« on: August 12, 2013, 08:34:16 PM »
Whats the 5D2's theoretical hardware limit for its CF slot max speed?
I saw benchmarks of the 5D Mark II reaching write speeds slightly over 90 Megabyte/s, just like the 50D.
And the 5D Mark III even reached 130 Megabyte/s. Its SD-Card controller's hardware limit is 21 Megabyte/s.

Raw Video / Re: Fake_HDR shot with RAW
« on: August 02, 2013, 06:08:40 PM »
These software lack control over the DNG and their debayer algorithm is bad.
Since the DNG format was created by Adobe I thought that Adobe software should handle DNGs very well. And from my experience ACR has a great debayering algorithm. So I'm curious: Which software do you recommend? ???

Raw Video / Re: What causes pink frames in raw footage on a T3i?
« on: July 27, 2013, 11:45:56 PM »
If your buffer fills up you'll get pink frames. To avoid it, set the resoltuion in the Canon menu to 640p @ 30 fps (Lower YUV buffer = more space for other stuff) and use 'FPS Override' to lower the framerate. Also, make sure you have a fast SD-Card that reaches the 600D's 21 Megabyte/s write speed limit and set the 'Pic Quality' to 'SRAW' (And reboot your camera!) to increase the shoot_malloc buffer size. That should help to get rid of any pink frames. If they still appear you can try to use an older build.

By following these steps I haven't got any pink frames since weeks.

Raw Video / Re: Why RAW insn't Cr2, and it is DNG, instead?
« on: July 15, 2013, 03:23:33 PM »
Would you give me some detail, pls ?

thanks :D
Sure :D

It's in the description of my YouTube video:

- Converted the .RAW files to .DNG files with RAW2DNG
- Color grading in Adobe Lightroom 4, exported as uncompressed 8-bit .TIF files
- Opened the .TIF files in AviSynth, upscaled them to 1920 X 768 and exported as .AVI files using VirtualDub and Lagarith Codec
- Edited in Magix Video Deluxe MX and exported as .AVI using MJPEG Codec

(You see, a very time consuming, low-budget workflow. I'm using a few selfmade Batch scripts so that I only have to do the color grading)

My AviSynth script looks like this:

[Spoiler]
LoadPlugin(ScriptDir()+"..\Avisynth-plugins\nnedi3.dll")
# Get the Plugin here: http://web.missouri.edu/~kes25c/nnedi3.zip
# Edit the path if necessary

# Get the Plugin here: http://www.compression.ru/video/smart_sharpen/src/smart_sharpen.zip
# Edit the path if necessary

ImageSource("PATH TO YOU TIFF FILES\%d.tif", FIRST_FRAME'S_NAME, LAST_FRAME'S_NAME, FRAME_RATE, false, false, "RGB24")
# That works only if your TIFF files are named like this: 1, 2, 3, 4, [...], 678
# Example:
# ImageSource("D:\Videos\%d.tif", 1, 300, 24, false, false, "RGB24")

nnedi3_rpow2(rfactor = 4)

ConvertToRGB32()

MSUSmartSharpen(3)
# decrease the number if it looks oversharped. The max. value is 5.

ConvertToRGB24()

Spline36Resize(1920, 768)
# If your aspect ratio isn't 2.5:1 you may want to change the second number ;)
[/Spoiler]


It loads the TIFF files which are created by Lightroom, upscales and sharpen them. Open this script in VirtualDub and export the video. It's easier with a Batch script. But I guess there are a lot less comlicated workflows out there- Just search and decide which one is best for you.

For any other questions you have to relie on the communitie. Tonight I'll fly to England for hollyday :)

Raw Video / Re: Why RAW insn't Cr2, and it is DNG, instead?
« on: July 14, 2013, 09:16:26 PM »
(thanks for motivating me further.....to sell my just-bought-for-that, 600D)
All I wanted to say is that the 600D is way more limited than the other Canon DSLR and that most tests on YouTube look like crap :D
Sorry if I killed your enthusiasm about your new camera. That wasn't my intention. But don't forget that the 600D can film in normal H.264 too and that it doesn't look bad. Just because it can't film perfect RAW videos you don't have to sell it!

question:  at a first glance the video looks nice(!)
In your opinion, considering also the post production job, how much better is this, if compared with the best result obtainable without using ML?
I'm also quite happy with the quality of 1280 X 512 RAW. It is not as good as a 5D Mark III or 50D and probably even the Blackmagic Pocket Cinema Camera will be way better than that but it's OK. And it's very nice to work with it.

My workflow isn't perfect since I don't use expensive software. But I'm happy with it. It's time consuming, but I'm happy with the result.

I think, I'll use RAW for some projects if I know I'll have much time to edit it. Otherwise I'll stay with H.264 and 1%'s great hacks with slice control and all that (See here: http://www.magiclantern.fm/forum/index.php?topic=6913.0 + Download: https://bitbucket.org/OtherOnePercent/tragic-lantern/downloads). Both versions have their benefits and I think you can make amazing stuff with both too: RAW & H.264.

Oh and by the way:
This sentence of mine: "And why on earth do you want to have a converter that creates useless .raw video files from usable .cr2 image files?" was the answer to this question:
"I was asking the opposite: being cr2 canon RAW propietary, would possible a CR2-2RAW,  to be able to use an  alternative open RAW, instead of dng?" Maybe I haven't understood the question ...

Raw Video / Re: 550D raw video recording port official thread
« on: July 14, 2013, 07:13:23 PM »
the quality I'm seeing is the best one I can get, it just looks bad for being a "720P" image
I'm not using the 550D but the very similar 600D and in my opinion 1280 X 512 (2.5:1 aspect ratio | doesn't work coninuously ...) looks good if you edit it correctly.
You have to keep in mind that you're working with uncompressed and completely unedited bayer data. So using Adobe Lightroom or CameraRAW for debayering and a very good upscaling method to enhance detail is a must to get sharp images without aliasing and moiré.

If your 1280 X 720 videos look bad in your opinion I think you may have a weak spot in your workflow. But of course you're right, our cameras aren't really good for RAW videos since they have such slow SD-Controllers and very small buffers.

23
I looked all over the forum for a fix for these vertical stripes..
But they are not static and I found no way until now..
Well. They aren't in the normal H.264 videos, right? So I'm sure there's a way to remove these stripes. Let's hope somebody will find it soon.
The film looked very good and the story seems interesting. I'm really looking forward to the actual film :) But the stripes are a bit disturbing (Although they fit the movie's tone)

Ich drück' dir die Daumen :D Der Film wird bestimmt was abräumen.

24
its on RTL soon? ;)
Hopefully not. You know, the 'N' means niveau ;D

But the trailer looks good except the strong vertical stripes at 0:10. Is there still no way to fix that? ???

Please don't torture yourself with the command line. Just Drag & Drop your .raw files onto the RAW2DNG.exe and voilá! Everything starts automatically :) Everything else just makes the workflow even harder than it is already.
