that's amazingly fast.  thank you...

confirm it's fixed  YAY!!!!

tested with 5D2 and 5D3 files

5d2

5d3

both extracted fine on linux mlv_dump but fail on windows mlv_dump

[THANK YOU FOR THE NEW FIX]

Hi g3gg0

few of us think mlv_dump for windows have a bug with large images such as those comes from full frame sensors.  can you investigate

http://www.magiclantern.fm/forum/index.php?topic=12733.msg123171;topicseen#msg123171


EDIT:  THANK YOU FOR THE NEW FIX

there should be another battery (round flat one like for watches) to keep camera internal clock.  usually have to remove a screw to access it.  try googling that.

so who is the author for mlv_dump for windows. can they help investigate?

Hi Tony

I wish to report that MLV Converter 1.9.2 (MLV Converter.exe) is not able to process MLV files created with full frame silent pics.

However the mlv2dng.exe  from MLV Converter 1.9.2/Tools/mlv2dng.exe  DOES generate DNGs but there are black bars as can see here

I've been working on saving silent-pics and full resolution silent pics in MLV containers. The data from the full resolution silent pics has OB areas included. When using MLRawViewer to open these MLVs, it doesn't seem to be respecting the 'active_area' fields of struct raw_info (in the RAWI chunk) and outputs DNGs with the OB black bars in them. mlv_dump processes these correctly. For more information and some sample files see: http://www.magiclantern.fm/forum/index.php?topic=12733.0

MA Visuals with 5D3, can you make a small MLV file and upload to dropbox so Linux and OSX users can try to convert with their  mlv_dump 

I have a feeling Linux user will be able to extract DNG without black bars just as for my 5D2

thnx Josep

confirm:  I too were able to process Attero's MLV with no black border on Windows 7/64




Attero, use mlv_dump to proccess http://www.magiclantern.fm/forum/index.php?topic=7122.0

[see post 17 on first page]

Just an update everyone.

I asked josepvm to process an older mlv file that were made with mk11174  build  (see post 17 on first page) and guess what

josepvm's linux version of mlv_dump produce DNGs with no black border

Here is what Josep wrote

Done.

Exactly the same behaviour.

With my Linux build of mlv_dump I can extract the 5 images and they look fine, no black borders. But I get the same error message:

Code Select Expand

With the Windows version of mlv_dump, same behaviour also as with previous mlv file. I can't extract the images:

Attero, what camera model do you have?  what OS do you use?  If your MLV is small enough, maybe you can put it on dropbox and someone who using Linux can try to mlv_dump and see if black border goes away

[they do not show the black borders]

Last night I asked josepvm to compile a fresh build for my 5D2.  He did it by using build from the current "fullres-silent-pics" branch including the modified "silent.c" from dmilligan, for saving silent pics in mlv or raw files.

With his version I was able to create this MLV

https://dl.dropboxusercontent.com/u/63842491/00000001.MLV  (188mb 5 pics)

on Windows 7 64  I was able to extract the 5 dngs using either

a) MlRawViewer_1_1_7
b) mlv2dng.exe   found in MLV Converter 1.9.2/Tools/mlv2dng.exe

the DNGs from the above shows black bars

-------------------------------------------------------------
-------------------------------------------------------------

josepvm asked me to send him the https://dl.dropboxusercontent.com/u/63842491/00000001.MLV  so he can "try to process it with mlv_dump, to see if this way the black borders are seen also."

here is his reply

I have processed the MLV, got 5 DNG images, and they do not show the black borders seen in your DNG.

This is one of the images I have processed from th mlv file:

https://www.dropbox.com/s/cdlu54kbtrlorub/00000001_frame_000000.dng


But there is an issue. When processing your mlv with mlv_dump I got this error:

Code Select Expand

The 5 files have been already extracted before the error occurs, and they look all fine. But I do not see this errors when processing my own mlv files. The output I get is:

josepvm explain that his copy of mlv_dump is build by himself from source, ML unified branch.

But is a Linux version, he use Linux exclusively.  It will not work in Windows.

Am asking other developer to look at my
https://dl.dropboxusercontent.com/u/63842491/00000001.MLV  (188mb 5 pics)

and see if you can extract DNGs without black bar like josepvm did with his Linux version of mlv_dump
Please state which OS and software you used.  Thnx

I want to know too. 

what's the best practice for 64gb card and ML and 5D2

ML have a smart feature where before formating, it will backup ML stuff, then format the card, then restore ML from backup.  I have always assume its backup to memory in the camera.

Went back and tested with your module saving in plain dng and the framing/centering are correct.

Confirm, in save as DNG mode,    it centered without black bar

update:

over exposure problem solved.  as alex instructed:  exposure override must be on

am also able to extract the DNGs  by drag and drop the MLV over mlv2dng.exe,  which is located in  MLV Converter 1.9.2/Tools/mlv2dng.exe  The GUI fail but the exe works  YAY



EXIF is correct too:   1/6 sec;   f/11;   ISO 100

While this method does works.  Here is the errors I get in mlv2dng.exe



PS am using mk11174's https://bitbucket.org/mk11174/magic-lantern/downloads/magiclantern-Nightly.2014Jul19.5D2212.zip
nightly build cause hard crash where I have to remove the battery

am guessing nightly build didn't have the EDMAC changes in the autoexec.bin

PS: huge thanks to dmilligan for making it MLV build

I have upload my MLV for those that want to play with it.  It's 5 pics in a MLV (188mb)
https://dl.dropboxusercontent.com/u/63842491/00000004.MLV

5D2 and 64gigs Lexar Pro 800x UDMA 7

Do you have the mlv_play and mlv_rec modules loaded too??? I think both have to also be loaded to make this link correct.

You are so right.  I got it to work.  Here you can see I have made 9 shots in a MLV file.  The viewer am using is MlRawviewer v1.1.6



As you can see the EXIF info are there   YAY !!!!

here is the problem, I can't seem to be able to convert the MLV to DNG

So far I have tried with:
MLV Converter 1.9.2
MLVMystic v0.5

both create empty folders with no files.

BTW the MLV file is 00000000.MLV.  they are over expose and blurry pics while I held in front of computer screen while intervalmeter doing its thing  (a shot every 5 seconds)

trying on my 5d2

tcc: error: undefined symbol 'mv_fill_wbal'
tcc: error: undefined symbol 'mv_fill_rtci'
[E] failed to link modules

What I did was take mk11174's
https://bitbucket.org/mk11174/magic-lantern/downloads/magiclantern-Nightly.2014Jul19.5D2212.zip

and swap out the silent.mo

also. might want to view on another mac laptop

can you re share this?

Where can I find the Magic lantern file for the 7D to download from the Mac?

go here and choose your 7d

http://builds.magiclantern.fm/#/

got MLV done too, hooray for metadata!

am I understanding this right?  full size silent pic with exif info?  no freaking way!!!!!

please someone compile this for 5d mark 2 so i can test it out.  please please.

with the 24mm 1.4 you can capture the mikyway at iso 1600

i have the rokinon 14mm 2.8 now and its ok.  the 24mm 1.4 is on my next list.

I think you did a wonderful job. I enjoy watching it. Thanks for sharing

Option to save using the raw video file format (much faster than DNG):

Would this have problem with 4gigs file size limit?

Can someone compile this for 5d Mark 2 so I can test it.  Please 

Maybe it will solve my 2 solid black frames problem.
