General Development / Re: A guide to dumping image buffers
« on: July 07, 2014, 01:05:25 AM »

Thanks for the answers  ;)

between the time i mentioned that 2000 already read this and right now, only a few hours have passed by, and look for yourself the number is at about 2200, ...thas 100 people have read this just in the last few hours.... so yes, i would consider this thread and this issue of huge interest to users, even if most might not understand how this here all works.
(i am definitely also one of them ,who still doesn't quite get it, how this all here ends up with results so far :-\

Alex, will you be able to fix the issue for the HDMI signal and the MArk3 "without" having to wait for lower res and older canons dumps?
its been a year now since i started this thread on bitbucket , and it seems over 2000 people have read this thread here , which was only started a month ago.
i think this shows people are watching this issue very closely... and are interested in it ... right?

Thanks, so now I have the 5D3 pretty well covered, in pretty much all modes.

so many days of silence, has the Effort not lead to any results?
Does this need more help from others?
is it being stopped now this attempt to fix this?


 :o :(

Crashes :


i had several blank screens (do you call that a crash?) when it was taking the dumps, usually its when raw is turned on and in raw recording or on raw playing back.
when i checked the dumps, exactly those screen DNG's from those so crucial dumps in Raw mode were corrupt.
Alex does it matter ?
when "not" in raw mode dumps worked fine.


we all want to shoot video in raw, without raw, ML is not needed on a mark3.


i am not sure, but if that dump would happen not 5 seconds after, but 10 seconds after, may it would work better ?
it seemed the Monitor screen needed 6-9 seconds to get turned on and into preview mode....



Does the crash happen before the beep, or after? (couldn't tell from the video)

Here the Dumps with forced VGA here through wetransfer :

Available until

[size=78%]i don't have  a SD monitor, nor will i ever buy one,.... The Canon mark3 LCD internal screen has more resolution than an external SD Monitor.[/size]
then  a Lupe is what anyone would use instead of staring at a bigger screen and really low and really bad out of focus resolution.
[/size][size=78%]i threw away all those RCA cables as well,   its 80's technology.. no need anymore of this low res stuff. [/size]

ALex,


anything else i can do to help you?

Thanks, so now I have the 5D3 pretty well covered, in pretty much all modes.

A screenshot from the emulator, from last night:


(it's not doing anything useful yet, but it shows the emulation goes far enough to load these dumps, display them, and check the alignment of ML overlays)

Here's one from today (loaded a HDMI dump from 5D3 1.1.3):


Does it match what you see on the monitor?

Other cameras too, please! Even if you don't have an external monitor, you can still do the built-in LCD dumps. If you have the A/V cable, you can do the SD monitor tests just with that (no need to actually use a monitor, just plug the cable).

i only got a mark3... i am not even sure if i made any mistakes, for the dumps happened (or didn't) when my monitor went black through some of the dump-processes sometimes for more than 7seconds.
it would be a shame to waste alex's time if my dumps were partially incorrect....but i have no way of knowing if all or some were fine.


i think twittering this cropbar fixing project on autoexec ML twitter account could get people doing dumps which follow ML more intensively  and those followers might have more cameras to do them with.


seeing the crop bars during recording is one thing, but playing back a video and missing then the cropbars, will that be also looked at here at this process to fix the crop bars?





Alex, I will try what you suggest with the 600D tonight.

Akos, Thanks for providing dumps for your camera! Do you have access to any other EOS cameras?

Do you guys think it's a good idea to make a spreadsheet so Alex can check off each camera when he has sufficient dumps for a particular model? I think it could have camera models vertically and the 5 display modes horizontally.

Alex,


wouldnt it help to post a twitter out on asking people with these dumps may be?





Looks fine, thanks.

For 600D, you may also try the lowest FPS you can get. If the writing process takes place between two frames, I think it should work. Try a few times to increase your chances of success.

I could also try to write the files in very small chunks (it will be slower, but might help).

Thanks Alex,



here is 5 short iphone clips i made ,you would be able to see different variations here clearly:

ALex,


Here the dumps from my Mark3, with 113 firmware, ML from today, 22 Dumps with monitor , 22 without, following from lists from Joahanan:

---duplicate, ignore---

you might wanna look at what i do before you go out  like this... i was sponsored and am sponsored by about every major leading photo brand out there, for the last 25 years or so ;)

15
You're kind of a stubborn fellow, aren't you?

seems rather they are all windows programmers here...LOL

you will see this topic becoming very real very soon, then i am sure you will have all intentionally forgotten all your comments here i gather.. LOL

16
I think you have misunderstood the concept of a number with a "K" behind. That number is not the total number of pixels of the sensor, but the approximate number of horizontal pixels.

Also, it is so far not possible to read the whole sensor without actuating the shutter, so 22MP filming is not, and will not become, a reality.

Please be quiet now.

4k horizontally and 1,7 k approx vertically ends up at about 6mb frame size, with the mark 3 its a vertical res of 5760 ...you do the math now!

i have been talking to Canon about this by the way....so you better be quiet yourself on your end...!

17
in 1983 i had the first sinar CCD sensor in my hands and a few people, like you, said this is never going to be bigger than this scan chip of 3mb ,it took a 5 minute scan to take a picture actually.
 which was handed over by the NASA to kodak and then to SINAR cameras in switzerland to develop the very first Digital camera ever for consumers and not just for astronauts.
it was a 135'000$ chip.

took great images....

but questions and ideas that are wanted are important to be put into the spotlights, so dont be so freaking negative and patronizing,and belittling pointing out small irrelevant factors like the the abbreviation of Mb or dreaming about an idea,
 may be i am the guy that can put you on a table with the people that actually manufacture this chip....

food for thought!

Come back here when you are no longer under influence.

On-topic: already done, but only 3.5K on 5D3, and it probably stops after half a second or so.


nope it would be almost 11k capture,.... to be exact it would become 5760 to 1700 for  xample  thats about 8k not 3,5 k

19
Canons5 dmark 3 sensor is indeed :Approx. 22.10 Megapixels (5760 x 3840)

http://www.usa.canon.com/cusa/consumer/products/cameras/slr_cameras/eos_5d_mark_iii#Specifications

so when you do your homework come back again, but not before please!

you are totally not reading what i just am describing here, let me ad a link so you can see what this is about...:

https://www.icloud.com/photostream/#A45aDWbrBEGxO

if you read more carefully you will see this would become a 11k capture, that about 3 times of what the big Alexa Cameras can do.. !!

there is no lens that could do this ever, since the pixels are not being accessed on this big chip..... the key is access to all 22mb pixels and not just the 1920-1080 which is only every tenth pixel on that chip...

Hi Guys,

i stumbled over a video that shows how to shoot in 3x crop mode at full res with magic lantern

although this is NOT a widely needed feature at all, to zoom in at full res….  it accidentally shows a solution for a very much wanted feature at the same time.

Panavision's cinemascope ratio 1: 2,3

most serious DP's want to shoot in 1:2,3 cinemascope panavision ratio,.. which usually only can get done properly with an anamorphic lens like the Panavision adapter 7200 , which squeezes optically the width and leaves the hight , …. and then with a field monitor that understands how to squizz anamorphic as well , and after in expanding it again in finalcut for example.in order to max out resolution of the chip of the camera.

of course this happens only with that smaller amount of access of pixels on the chip, which is very counterproductive to say the least.

a nightmare to be exact. and huge workload in the aftermath of using such optical anamorphic compressors, which need to be uncompressed after again in final cut etc..

but what you guys at Magic lantern have opened here is a new very much wanted access to the chips full res of the the chip.

in this video here : http://youtu.be/WhiQ9D9vyPI

he shows how you do the 300% AT FULL HD RES ,  or 3 x crop at full res.

if you were to do this,... but widen the YELLOW AREA spot to use the max width of pixels available on this chip ,
see first two picks , which are from this video, but then SEE MY 3rd EXAMPLE pic BELOW , you would have actually created a widescreen 1:2,3 ratio easily without ever loosing resolution any other way would loose , 
and of course the way AN OPTICAL adapter anamorphic ones would loose ,

again : THIS is a VERY big deal !!!!

if The Magic lantern crew would venture into this they are looking at a .."8k-11k".. capture, that's about 3 times more than an alexa can shoot with. Alexa Cameras  shoot at 4k, by the way..... its about the ma possible today
 (i will not talk about shitty RED camera stuff here, so don't ask)


these usually optical anamorphic adapters start at 1500 and go up to 10k, and most are not even built anymore.
even with those optical anamorphic lenses the resolution then is not even remotely close to what your crop mode , when used with max width use of all pixels available on this  chip could give us all …

see third image below where i enlarged the yellow are so it helps you may be understand this very sought after feature amongst P's out there..

also with adapter that create anamorphic compressions optically one is very limited to shoot closer than 4 feet…. so in reality this all is a big nightmare.

and your software could solve all this issues !

please let me know if this is something you are actually reading here, ….

Akos

i wish you insert image feature would actually work here, then i could attache 3 images that would visualize this very well, ....

here a link to the images that can show this easier ,.... and nope , this is not an optical challenge at all i am describing here with Magic lantern , so anyone suggesting optical solutions here , please read more carefully or leave this thread ..
