@baldand.  The link to your repository in the OP is generating a phishing attempt error in firefox.  The username before bitbucket.org needs to be removed.

https://bitbucket.org/baldand/mlrawviewer.git

Cheers.

Whoops, fixed now. Sorry about that.

Hi there,

I must be missing something completely here. I'm using MLV for the first time ever on a 5dII. When using mlrawviewer the video looks like crap: not sharp and colors are all washed out and sort of pinkish.

Please help: what am I doing wrong?

I've used the latest night build magiclantern-Nightly.2014Mar29.5D2212
and MlRawViewer 1.1.3

Cheers, Frank

It is preview.
Click "Export" (E key on keyboard or Red icon on left panel) to export to DNG and then look DNG :)
Also see issues about ACR color profiles:

Unfortunately the video quality is still very bad after exporting  :( . Some examples (password is MLV):

During recording in the viewfinder it looks all right. I must be doing something very wrong  :o

The black level is wrong due to a bug in the version of mlv_rec you used, so those files would need to be manually fixed to be displayed or converted correctly.

You need to upgrade to a newer ML with correct black levels.

great to hear there is a bugfix  :D. I downloaded the version that is in the first post of this thread.

https://bitbucket.org/baldand/mlrawviewer/downloads/MlRawViewer_1_1_3_win32.zip

Where can I find a newer version?

For the record: I was able to correct the video using ACR but it was a lot of work!

As I understand it, the bug was in Magic Lantern - not MlRawViewer. Sorry, but I don't know any of the details about the fix.

Hi baldand,

It's fixed: On Magic Lantern's Movie menu goto RAW (MLV) then go to the sub settings and find Fix black level turn it OFF

Thanks for your good work!  :D

First, I want to say Thank you for making this marvelous tool.
BTW I have some questions about this program.

Any Plan making MLV browser which can browse thumbnails of all MLV files in a folder?
like



+

Parallel processing at once per CPU core. (at least 4 converting processes at a time.)
such as

Very Impressive tool :D
Baldand, which post-processing do you recommend after using your tool to make apch 4:4:4 MOV file?
(e.g. After effect? Da Vinci? premiere?)

OR

You may recommend to output DNG sequence not MOV file.

Any answer would help. Thanks

Sorry if this has been posted before, I've done a search but couldn't find anything related.

Using MLRawViewer I can export to .MOV fine but nothing happens when I try to export DNG?

Some info:
https://bitbucket.org/baldand/mlrawviewer/issue/21/batch-encoding
"There is now an export queue which processes jobs in sequence. However, the old MOV encoding doesn't use the queue yet, only new DNG exporting."

Btw, baldand, out of curiosity, how did you make the executables and package this for windows and mac?

Thanks

The feature that I'm missing the most is the ability to use all the CPU power when exporting dngs, it would make a HUGE difference in my workflow and I suppose the ones of everybody!

I don't think it would. In most cases the speed of conversion to DNG format should be limited mainly by your read or write speeds (whichever is slower) - it should be I/O bound, not CPU bound.

Of course if your MLV file is on a fast SSD, and your target directory is on a different SSD, then you might start to become CPU bound instead.

This might change if/when there is more processing being done to the raw data than just 14->16 bit unpacking and dead pixel hiding, at which point multithreading of the frame processing may help.

I agree. People seem to forget that moving several Gb from a CF card unto a hard drive takes time in itself. Simply copying about 64Gb from the CF card to an internal 7200Rpm hard drive takes roughly a little over 10 minutes using USB 3.0 and a good card reader.

I just have an internal ssd so I can't make any serious test, but I remember that once this software (which has multithread and sadly doesn't always work, http://www.magiclantern.fm/forum/index.php?topic=7825.0) worked and it was *a lot* faster.

optimizing the IO-threads is not that easy (but there are some good ideas out there :)), there are several possible bottlenecks. one of the simplest things is to convert straight from the card - it simply prevents the time consuming copy-process to a harddisk - if you summarize all copy/process time, its not that clear, what concept is ideal. i wouldn't focus that much on multithreading but more on one-click-batch-solutions, so you can start your main (editing) work straight after a unattended coffeetime.

and: baldand gave his sourcecode free to help and code, in contrast to me (yet). you're all able to help ;)

thanks for the software MLRawViewer. 

Does it remove pink/green dots for 650d?  Can it be builtin? :)

During an raw/mov export, Can video viewer/display be disable during an export just to save CPU/GPU?
Will there be waterdrop WB tool in future :) ? or I can enter the same numbers for WB so I can lock in the setting during mult clips export.
thanks
