Have you tried any of the speed improving tricks? Your test seems quite superficial.

First listed table here: http://www.magiclantern.fm/forum/index.php?topic=8000.msg72051#msg72051
Let's try to populate it ! It will be a very useful and precise reference !  ;)

Raw Video / Re: SD or CF For Raw video
September 03, 2013, 02:20:32 PM
When the video tests table (first in the list) will be populated (hope soon), we will reference to it in order to decide for the best CF cards and cameras for the resolutions we want : http://www.magiclantern.fm/forum/index.php?topic=8000.msg72051#msg72051

[1] We can do ML "burst silent pics" but they are high resolution, raw (not lossy) and very low FPS (not suitable for normal movies).
[2] We can use Canon normal burst mode with jpg, but at very low FPS (not suitable for normal movies).
[3] We cannot process the raw video data during acquisition: we are reading the raw video frames data from the Live View buffer.
[4] Post-processing in-camera must be realtime (if you want to process the raw flux down to lossy as you want) but not enough processing power is inside any current camera.
[5] We cannot process h264 lossy video data during acquisition, because H264 compression is done in-camera inside a "black-box" no one can access inside directly.

So... good ideas, but not at all applicable here... sorry  :'(

Hello guys! I got a 1000x 64GB KomputerBay Card and would like to try how it works on my 5D2, I´ll post my results here. But I wonder if there are already some conclusions about the various cards how to format the cards to achieve best speed results. Is there any table for that out, yet? Thanks! Martin

Post your results here (video tests section) : http://www.magiclantern.fm/forum/index.php?topic=8000.0
So all the tests will be in one place easily findable by anyone !  ;)

Thanks! I used Instant HD to stretch the last image. But it doesn't make a huge difference, just stretching a composition in AE does the trick.
You're right, 0.1x etc. is the bitrate of h264 in ML. I noticed that if I don't go over ISO 800 I can film on 3.0x without stopping. And it does make a difference.
I'll make some more tests and add it to this post in a while.

Great ! I'm keeping an interesting ML directory, where we can keep together all our tests. Go here and then select the first item (video tests) and then begin contributing ! I also inserted this tests you made ! I hope you like the idea ! --> http://www.magiclantern.fm/forum/index.php?topic=8000.msg72051#msg72051

It would be useful for all to converge here in a more organic sheet, if you find it useful: http://www.magiclantern.fm/forum/index.php topic=8000.msg72051#msg72051

Select the first links about the testings ! Many thanks !  ;)

I did some comparison shots

H264 0.1x  1920x1080 16:9

H264 1.3x  1920x1080 16:9
http://i.imgur.com/MXH8PBzh.jpg
H264 3.0x  1920x1080 16:9 cropped to 2.35:1
http://i.imgur.com/jGHDmvR.jpg

RAW 2.35:1 / 1152x490
http://i.imgur.com/sXCT4rk.jpg
RAW 2.35:1 / 1152x490 stretched to 2539x1080
http://i.imgur.com/ICh2yMU.jpg

There's no doubt which one looks the best :) RAW is so much sharper and natural looking, also having the ability to edit it in Camera RAW is just unbelievable and it upscales nicely.

VERY interesting ! Many thanks ! Can you tell what software and parameters inside it you used to stretch the last image ? Many thanks !
Also: what means 0.1x - 1.3x and 3.0x ? Zoom factors of the lens or the "quality factor booster" of h264 magic lantern ? Or what else ?

Hi folks !

It will be useful if you can share all of your testings about raw video recordings data and card speeds here: http://www.magiclantern.fm/forum/index.php?topic=8000.msg72051#msg72051

So this thread will not bloat !  ;D

Select the first links about the testings ! Many thanks !  ;)

General Help Q&A / The ML resources directory
August 31, 2013, 02:55:23 PM
This thread wants to be of help as a reference links directory repository to all the ML resources.
This main first post is constantly updated, and if someone knows other links to ML or related interesting resources, please: chime in by writing into this thread ! Many thanks in advance for everyone that will contribute !


======== GENERAL INTEREST ==============================================================

THE ML REFERENCE VIDEO AND PHOTO RECORDING TESTS
It is a Google docs spreadsheet maintained by user "dlrpgmsvc" where all video and photo recording experiences from various ML users can converge.
The spreadsheet is read-only in order to keep it clean, coherent and precise, but everyone can give his contribution by submitting his experiences on the submission spreadsheet. Periodically, all the submissions will be transferred to the main spreadsheet after a minimal check. Important: if you see your camera-resolution-card has already been covered, don't hesitate to give also your data, because results vary within the same camera models and cards, so, the more results we have, the more we can know on how to expect about the variance between the same cameras and cards!

CURRENT RAW VIDEO CAPABILITIES - ALL ML CAMERAS
It is a Google docs spreadsheet maintained by user "Roman" where all raw recording capabilities of various ML cameras are listed.
Inside this spreadsheet there are also many other sheets where various technical caracteristics are listed for every camera, most are specialistics for developers only, while others are ineteresting also for the normal user.
The spreadsheet is open for modifications to all.

@dlrpgmsvc

we can actually record in crop mode with shallow depth of field
but it needs huge distance and telephoto kind lens

True, so not viable for normal cinema use (big and bulky tripods, optical stabilizers, and great spaces, not viable for indoor use, and so on)

I made many in-deep analisys on anamorphic lens: they don't worth the money, at the end of the story. The vertical resolution gain is not worth for our hobby: a wideangle corrected in post is much more viable and with very good results. Anamorphic has so many limitations, also for focus distance limitations, bulkyness, main lens coupling and so on

There are no solutions for crop mode in order to keep all the features we want (I made a simple compendium) :

[1] Wideangle lens                                                      : FOV enlarged (GOOD) - DOF very deep (BAD) - QUALITY good (GOOD) - Record on narrow spaces (GOOD) - Must defish for large FOV losing resolution (BAD)

[2] Wideangle add-on                                                  : FOV enlarged (GOOD) - DOF very deep (BAD) - QUALITY worse (BAD) - Record on narrow spaces (GOOD) - Must defish for large FOV losing resolution (BAD)

[3] Normal lens + operator step back to take more FOV :  FOV enlarged (GOOD) - DOF very deep (BAD) - QUALITY good (GOOD) - Cannot record on narrow spaces (BAD)

[4] DOF adapter (projection method + macro mode)      : FOV enlarged (GOOD) - DOF shallow (GOOD) - QUALITY horrible (BAD) - Record on narrow spaces (GOOD)

@Monti : your test is not correct. You are progressively going away from subject (the Matchbox) by lens or by crop factor or by 50D phisically (not important). You have to test at the same framing the normal, the 5x and the 10x, so that the Matchbox occupy the same area on the sensor. It is obvious that more you go away from Matchbox and the more you have DOF. Can you redo the test in this way ? Only in this way we can judge

yeah well let me think about it...

we talking about framing the scene isnt it?

so lets say i shoot a person head

my depth of field is like from his nose to his ear

that is shallow one.

now if we zoom in in cr2 we get what?

head is choped half and we need to reframe it

when we reframe it what happens?

depth of field is not narrow anymore

now my depth of field is whole head and much more

not as shallow as it was when i frame just nose and ear

why is that?

because crop mode means 50 mm becomes 250 mm

now i have to shoot from distance not 4 meters but like 20 meters to get kinda same framing

and 20 meters gives me what? huge fat bulky depth of field that i can even bring a bus into it

p.s. of coz u dont get head shot on 50 mm from 4 meters
but u got the point

Totally wrong again. If you frame the same size object, the dof is the same at all focal lengths. http://www.cambridgeincolour.com/tutorials/depth-of-field.htm

and thats an idea Andy600!

so 18-35 f1.8 sigma lens comes into the game

first part 18 mm it is going to be 28 mm f2.8 on normal and like 85 mm f 8 on crop x5 mode 200 mm f 16 x10 mode
double it with 35 mm gives you 50 mm f2.8 on normal and 180 mm f 8 on crop x 5 and 400 mm f 16 x10 mode


Wrong. Totally. The f-number doesn't change at all with crop factor!

Reverse Engineering / Re: ADTG and CMOS registers
August 26, 2013, 07:37:19 PM
Now that mk11174 managed on how to find the registers to do Dual ISO for video also for 550D, do it's easier to find also them for 50D, that is doing only dual ISO for photo ? If someone can tell me the current state-of-the art on dual iso for video on 50D, I can inform me from mk11174 on how to proceed also for 50D ! Many thanks anyone !  ;)

@1% - Just had a look at your TL commits. Nice work dude! I'll compile a new build tonight unless you already have one uploaded.

"photo mode raw for 50d" ? What is this into the details ?  :o
