General Help Q&A / ML disclaimer screen
April 13, 2016, 01:51:22 PM
hello,

is there a way to disable that screen ?



(couldn't find the info in the FAQ, sticky post, or settings on the camera)

thanks

Hi,

is there a way to take night stars silent full res MLV pictures with the ML intervalometer ?

I'm using a 11mm f2.8 lense, so it gives me a 30ish sec exposure if I want to avoid stars motion.
I read in the 1st post that taking picture > 15sec is not OK

is it still true ?

thanks
#4
yes i know, i posted the link yesterday (see above), I plan to try that today :)

thanks

edit : sh*t, I have a lot of dead pixels :'( http://i.imgur.com/678Wqfa.jpg

@Danne : I'm using a 60D, only a few pixels

here's an example, both processed from the same DNG file



#6
yes indeed it won't be the same :D this all automatise thing is for lazy testing mostly

for important footage i'll do the manual work in between with photoshop/lightroom

@Walter Schulz : yes thank you for the lmgtfy ... but as I said before, that's what I'm already doing.

I found a way to go from DNG to JPG in my batch using dcraw-9.26-ms-64-bit.exe -c -q 3 -a -w -H 5 -b 5 xxxxx.dng, but I need to fix the dead pixels now (found info there : http://www.dl-c.com/board/viewtopic.php?f=4&t=686)

i just wanted to do a batch that takes MLV and get PNG or JPGs at the end.
I'm doing this so far : MLVs > mlv_dump to DNGs > photoshop image processor DNG to JPG > assemble the JPG in virtualdub or Adobe Premiere

so the part in bold is what i'd like to automatise :)

I don't lose that much quality between DNG and JPGs (i set the max quality in photoshop when processing), they look very clean.

i tried DCRAW but I get a lost of dark/red/purple dots (dead pixels I assume) that I don't get with photoshop ... so, too bad :(
#8
i googled a lot, couldn't find any command based DNG to JPG/PNG converter.
I assemble the pictures with virtualdub for now.
checking MLVFS & MLV Producer, thanks

edit : MLV Producer looks interesting, but for now I can't achieve the same quality result as my workflow in the 1st post. I will continue trying it a bit more :)
#9
thanks :)
but i was only able to extract to TIFF or PPM.

any JPG or PNG solution ?

Raw Video / Convert DNG to JPG with command line ?
March 31, 2016, 10:47:57 AM
Hi all,

i'm trying to automatise the process from MLV files to JPG files
here's my workflow so far

I have this in a folder


I put my MLV files in the "_MLVs" folder, and then run the "BATCH_mlv2dng.bat" batch


This extracts all the DNG images from the MLV files and put them in the "DNG_output" folder


and from there I start manual work :
- batch process images in photoshop to convert the DNG to JPG
- import the JPG in a video software (virtualdub/premiere pro/etc ..) to make the final video

I'd like to automatise the DNG to JPG part too.
Do you know if a simple executable exists ? like mlv_dump.exe

thanks for your help :)

Raw Video / Re: 60D RAW video - it's working !!!
March 30, 2016, 03:36:50 PM
hi,

just tried the RAW video on my 60D today for the 1st time and ... oh god I don't want anything else now lol
i'm amazed by the colors and the sharpness !!

small tests :

h264 then raw
https://www.youtube.com/watch?v=FxTzNswv4r0

just raw with my canon f/1.4 50mm lense,
https://www.youtube.com/watch?v=OYf8edQmFG4

daylight (a bit too dark)
https://www.youtube.com/watch?v=K0Uxhqu8Ddw

to bad we can only record 5sec/7sec in "1080p"

i'm gonna read this topic now :)
#12
oh ok, thanks !
#13
I still don't get why it's stays off in "full res" and doesn't in "simple" :D
But I don't know anything about programming and dev, so i'll shut up now  ;D

thanks for the tip for intermediate resolutions, i'll have a look asap !
#14
@Walter Schulz: Thanks ! I had no idea those were actually the screenshots :)

@a1ex : indeed, so in "simple" mode, the LCD wakes up after every picture, but in "full res" mode, the screens stays black. I guess I can live with that ;) to bad for the battery life.

Since I got you here, do you know if it's possible to have a resolution between simple and Full res for the silent pictures ? like 2.7k ? or is it not technically possible ?
thanks
#15
thanks for your reply :) here's 2 videos to illustrate

for the simple MLV + intervalometer : https://www.youtube.com/watch?v=UHy7_I6dkc8
as soon as I change for "Full Res", the screens goes and stays black :)

and one for the screenshot : https://www.youtube.com/watch?v=dQ-5Sdx089M
(i have nothing on the SD card after that)

cheers !
#16
taking screenshots doesn't work here so ... :D



(don't pay attention to the other settings like intervalometer and MLV full res above it)
#17
will check tonight and let you know :)
#18
Yes it's activated.
As I said, just changing from "simple" to "full res" fixes it.
#19
but it works perfectly fine with full res, it's just the "simple" silent pictures that keep the screen on, no matter what.
#20
bumping this,

the screen doesn't go black with simple silent picture + intervalometer + image review off in Canon menu

can anyone else confirm ?

Since it seems you know your way around Windows scripting, one thing you might could do to help is that MLVFS for Windows needs a user friendly way to be launched (like the Mac version which uses an 'Automator' service for launching it). I was thinking a bat file that could be added as some kind of folder action via the registry (I think that is possible, at least for files, not sure about folders) to show up in the right click menu. That way you could just right click on a folder and see "Launch MLVFS Here" or something like that and it would startup MLVFS for that folder in the next available drive letter.

i'm not that good, took me a quite a lot of googling to make that batch. Sorry I have no idea how to make what you suggest :(

Why go from MLV to RAW to DNG? Why not straight to DNG with mlv_dump? You are loosing a lot of the metadata this way.

because i'm apparently freaking blind  :D
i didn't see it was possible ... hahaha

well, here's a simpler version of the batch then :


@echo off
cls

set /p INPUT="Input file (select your MLV file) : "
set /p COMPRESSION="Compression level (0-9) : "
set /p PREFIX="Prefix for the DNG files : "

mlv_dump.exe --dng -o %PREFIX% -l %COMPRESSION% %INPUT%

mkdir DNG_output
move /y *.dng DNG_output
if "%DELRAW%"=="y" (
del %OUTPUT%.raw
)
#22
Just place the following files together in a folder

mlv_dump.exe
raw2dng.exe
BATCH_mlv2raw2dng.bat
your MLV file
(optional, you can type its complete path if you want later)



start BATCH_mlv2raw2dng.bat
and fill the informations :



then it should start doing its thing



and then the RAW file is processed in DNG files



after the batch closes, your folder should look like this (if you answered "y" when the batch asked you if you wanted to delete the RAW file) :



your DNG files are in the "DNG_output" folder :



I hope this will be helpful, maybe I didn't search enough and there is a nice GUI around :D

can't find how to add an attachment and I don't want to host it somewhere, so here's the content of the batch !


@echo off
cls

set /p INPUT="Input file (select your MLV file) : "
set /p OUTPUT="Output file : "
set /p COMPRESSION="Compression level (0-9) : "
set /p PREFIX="Prefix for the DNG files : "
set /p DELRAW="Delete RAW file after ? (y/n) : "

mlv_dump.exe -o %OUTPUT%.raw -r -l %COMPRESSION% %INPUT%
raw2dng.exe %OUTPUT%.raw %PREFIX%
mkdir DNG_output
move /y *.dng DNG_output
if "%DELRAW%"=="y" (
del %OUTPUT%.raw
)
#23
ok I can confirm (canon 60D) the screen stays black with full-res + intervalometer, image review off in Canon menu
either in DNG or MLV

now i need to find a way to extract jpgs out of the MLV file :D onto googling !
edit : I made a batch :p http://www.magiclantern.fm/forum/index.php?topic=16725

thanks a lot for your help guys
#24
I can confirm the last version works fine ! (interval + HighRes silent pictures)
thank you so much :)

still doesn't go to LCD powersave mode though, but maybe there's no way to achieve that ?
#25
oh ok, his last sentence made me think it was an unfixable thing  :o
sorry about that, english is not my 1st language :)

That's some fast fixing ! thanks a lot @a1ex
