In every proggie I tested there is a pattern in the output (--no-stripes --no-fixcp does not help for mlv_dump), The only correct way to get valid DNG with working good/old plain black level is the method a1ex showed above (octave example).

regards

yes, I edited my post. original mlv_dump version and exiftools give dng without pattern. white balance is not the same as not-lossless

found.
combination of both options --no-stripes --no-fixcp produces valid dng without pattern.
use just one or none of these two and have a pattern on the image.


what I wrote above is not true. it's mlv_dump version. both "mlv_dump on steroids" and the one used in "simple right clic menu mlv dump batch" produce the issue. used the one in download section and works perfect after exiftool!

It was bouncyball's "mlv_dump on steroids", not the vanilla one.

you right, check this later

do the files look right in mlv_play? (if yes, it's the latter; if it shows similar defects, it's likely the former).

no, it doesn't. in camera looks exactly as on pc (bad)

Let's modify silent.mo to save both uncompressed and lossless versions of the same input image. Can you try this patch?

uh oh.. I'm going to study
meanwhile I uploaded .mlv on dropbox

Can you extract the DNGs with vanilla mlv_dump and retry the same command?

hi, thank you for answer, it was already "vanilla mlv_dump" as "mlv dump batch" latest version is based on bouncyball's "mlv_dump on steroids".
however extracted again.

with your command:

Code: [Select]
exiftool -BlackLevelRepeatDim="2 2" -BlackLevel="1920 1792 1536 1024" 6D_14bit_lossless.dng -v
[..cut..]
Nothing changed in 6D_14bit_lossless.dng
    0 image files updated
    1 image files unchanged

but with -IFD0:

Code: [Select]
C:\Users\marco\Desktop\mlv>exiftool -IFD0:BlackLevelRepeatDim="2 2" -IFD0:BlackLevel="1920 1792 1536 1024" 6D_14bit_lossless.dng -v
======== 6D_14bit_lossless.dng
Rewriting 6D_14bit_lossless.dng...
  Editing tags in: IFD0 TIFF
  FileType = DNG
  FileTypeExtension = DNG
  MIMEType = image/x-adobe-dng
  Rewriting IFD0
  Rewriting ExifIFD
  Copying 1 image data blocks
    1 image files updated

Also, depending on the raw processing software you use [..cut..]

yes, I read this so I used CR only.
fog here in my mind..  ???  should obtain same file as levas but I'm not able..

hi to all,

this is jpg 150% of NO lossless:

this is jpg 150% of after 1st exiftools command: exiftool -IFD0:BlackLevelRepeatDim="2 2" 6D_14bit_lossless.dng

yes, already tried exiftools and don't seemed to be alright but now I'll try again.
however, thank you. I'm not able to buy a 5D3 for this and all help is welcome.
I saw that losslell vs uncompressed is a big gap, permits to have all time I need to make short videos.
thank you again.

ok, thank you, so I used mlv_dump and that batch to extract .dng and this time at least are converted!

but

- I see a pattern on pics.. something as pixelation.. like sensor pattern
- black levels are not ok even with exiftool command

continue to try.. for the 2nd issue I have. for the first I have no idea :)

Again: Settings used?
Trý to understand we are not psychic and have only the information you are giving us.

I used: crop_rec_4k.2017Nov16.6D116.zip
installed on camera, my 6D
modules: crop_rec, mlv_lite
resolution: 1824 x 1216, 14 bit lossless, 3:2, preview auto, crop mode OFF

mlv_play on camera shows video well, but when extract .dng from .mlv are corrupted.
I use pismo+mlvfs.dll to mount .mlv and open .dng or raw2cdng.1.7.9 to extract

ok... mmm... non ok
tried lossless build and wasn't able to produce a single valid .mlv file

just tried 1824 x 1216 and doesn't work.
where am I wrong?

3x3 binning should improve noise and moire artifacts while skipping not. in 5dmk3 binning is employee in full hd res, what about this build? did you see moire improvement?

this evening I'll find time to install and report some trial

5472 / 3 = 1824
3648 / 3 = 1216

For 16:9 it just crops top and bottom.

You shouldn't need to re-balance the blacks unless you're playing around with the lossless compression stuff. It should be resolved eventually but for now it is a work in progress.
yes, so for x1024 there's a crop that I can do with software then.

I need lossless as 6D hasn't choice to rec a raw 1824 x 1216 without going out of buffer so I hope with lossless I have enough speed to rec at least 20 secs of raw video if not continuos at 1824 x 1216.

am I wrong?

ok, so.. if I need a full hd resolution and 1824 x 1216 works maybe best I can do is upscaling then crop.
but how can it work with 1824 x 1024 (16:9) with 3x3 binning if sensor is 5472 × 3648?
would to understand..

however:
before process images I need to run exiftool on all dngs to re-balance black levels (no hardcode in build here, right?)
for me that I don't need audio I would to help to make a strong build with all res working and black levels ok out of the box.
update firmware doesn't seem top priority to me.
thank you for your work and time.

hi, I'm a 6D owner with ML installed on. I would like to have lossless video raw as I can increase resolution with fast sd.
I would to test a build that works at least at 1824 x 924, is that build crop_rec_4k.2017Nov16.6D116.zip?

I'm here, if I can help.. even if I'm not so able but if you need to test something..
to reach higher resolution (and 3x3 binning?) is a must for me.

thank you all involved in this.

Raw Video Postprocessing / how to compile MLVFS on windows (x64)?
« on: July 18, 2017, 02:51:05 PM »
hi, I need help to compile MLVFS in windows.
any support would be very appreciated.
I tried gycwin with no luck: .exe file is created but 0xc000007b error when launched is reported.
my target is to create a build with no .log file inside as it hurts after effects imports.

thank you to anyone would help.

Raw Video / Re: Strange Pink Flickering in Nature and Brick Footage
« on: July 18, 2017, 01:22:45 PM »
please, share what you found, thank you

17
well, the problem is not the presence of *.log and _PREVIEW.gif but the NAME format of log file mounted.
to fix this it needs to be mounted with _ at the start of filename.
example:

filename.MLV > MOUNT > _PREVIEW.gif, filename.log, filename_000000.dng, filename_000001.dng ... etc
AE analyze filename.log as first file of sequence as its structure is similar to .dng files and returns error.

if filename.log is mounted as _filename.log everything goes well.

please would someone fix it or help me to modify the source and recompile.
thank you.

hi, is it possible NOT to mount "_PREVIEW.gif" file and "*.log" files?
these two files block AE to import DNG sequence dragging in the relative folder.
I can't find an option in command, and is a trouble as if I import all DNG files as sequence and not as folder when I render in camera raw just first file will be adjusted.
instead, when I import the whole folder, modify original is enough to modify overall sequence in the folder.

hope I explained well. thank you.
