Hi, that is interesting.
Could you implement batch export of some lower quality proxy movie files? Export time would be crucial, it could use some very basic, low quality encoding just to be fast and give an ability to work in a field even on weak laptops. Mlrawviewer is great but unfortunatelly it is not developed anymore, it has only high quality export and it can be very slow on older machines. My point is: im out for a couple of days,  i have only a basic laptop with me, i am shooting some things and i would like to check the footage, generate low quality proxys and work with them, change to full quality on desktop computer when back home. I have laptop with i5, 12gb of ram, weak nvidia 920m, 5200rpm HDD - mlrawviewer plays almost in real time. THere is no proxy option, export to high quality prores is painfully slow. Could you do something to improve that?

Actually, yes! I thought about it, and i did it in prototype. There are several ways to improve encode speed: H264 with low bit-rate, Fast PreRes codec, using leaner or pixeldemosaicing or even double downscale. Color space conversion does not affect the speed. I can implement a few methods.

And i forgot about the sound. I need mlv-samples with audio tracks. From different cams.

Nice App ! but I having black-level problems, green cast no matter what I set the level to, using 5D2 MLV files, black-level should be 1750  looks better at 2000
and at play back I get flashing frames some are B/W others are just white or black. Also Pink Hi-Lights in the close to over-expose areas, 
It's like the app is clipping the high-lights and crushing the blacks,
and to be clear there is not problem with the test MLV file as I have processed it thought Mac- MLVFS to A.E.CC/ACR export to ProRes4444XQ
also tested it on Windows 7pro with raw2cdng to Premiere Pro CC2014. It would be nice if you could explain the key functions and or Hot keys used.
For export , I think you should include Cdng's & I like the idea of a MLV header editor. One last thing, It would great to give the file Info (metadata) e.g. Frame W/H ,fps, ISO, etc....
Good job thou, keep developing this app I see big potential here.
Test computer: i5 dell(1764), 8GB ram , 240 GB SSD, ATI Radeon HD4300

Thank you!

but I having black-level problems
I just added black level control manually.
I have an idea to make auto black level calculation from the darkest frame.

There's green button. It should levels green to normal.

Can you send me mlv-sample with troubles? I have 50D that has the same black level. But it looks fine.

and at play back I get flashing frames some are B/W others are just white or black.
And i fixed the problem with frame cache.

In the near future I'm going to write the manual. But it's simple.
Three buttons: 1. Green Correction 2. Debayering method 3. Color space.
Then filters.

and or Hot keys used
There's no hot keys yet. But will be.

I think you should include Cdng's
I need to dig in cdng file format

Hi AWPStar, could you implement:
-in/out points for export
-lower quality preview but faster
-ability to drag/drop many files and buttons/hot keys for next/previous

WOW  Very nice =)   

Its open source ?   

If possible, please, please just integrate this http://opencolorio.org/  on the app for we use Cinelog from Andy6000 and LUT's. I don't have time for today to try out your app but if the recover buttons (shadows/highlight)  work good it will be just wonderful. In ACR you can't do this because you will have exposure change in the video.  Looks very promising =)   ...of course h.265 would be more nice  :P  8)

Hi @AWPStar - Nice idea! I have a suggestion/request. Before adding a bunch of editing/grading features, concentrate on integrating pixel-accurate, fast metering (i.e. a vectorscope, RGB parade, histogram etc). Most of these transcoding apps fail because the end user cannot accurately judge things like white balance, levels, saturation etc - it's not something that can be done easily without scopes, even by a pro on a calibrated reference monitor.

Also, why not just pickup development on MLRawViewer instead of building an app from scratch? The source code is available and it's 'nearly there' in terms of usability. It could use a more visually intuitive point-and-click GUI rather than hotkeys and, of course, meters.

If you plan to integrate certain ML algorithms (by a1ex) you will be required to publish your source code due to GNU licensing conditions.

Keep up the good work! :)

-yes
-yes
-Thinking about it. It is posible, but difficult to integrate with current cache system. And you bet i'll try.

So Cinelog is OpenSource, but i cant use it without integrading with OpenColorIO?

There is histogram. I want to add waveform/RGB parade. Vectorscope not now. mb later.

i don't know python. And sometimes it is useful to reinvent the wheel.
What ML algorithms (by a1ex)?

@AWPStar - Cinelog is commercial, not OS (some of it is artistic but mainly technical). We have our own processing routines for building special luts and camera profiles and we do all the math ourselves plus Cinelog can be used for many different cameras and colorspaces, not just ML/DNG. You can find all the transfer functions and primary transform math (the same data we base much of Cinelog on) in most camera manufacturers white papers and you could even implement debayering to Cinelog reference colorspace (a derivative of Log-C) if you want - the coefficients are on our website.

OpenColorIO is OS and can be implemented freely. There are ACES 1.0 configurations and basic 1D transfer function configs (default Nuke config) but there are presently no IDTs for ML raw shooting cameras (I'm working on those, or will be once we sort out the color meta). Cinelog OCIO config has a few more options, colorspaces and transforms for working with DNGs in ACR/AE/Premier and DaVinci Resolve.


re: GPU - there is a big (ugly) post about it here http://www.magiclantern.fm/forum/index.php?topic=11879.0 It applies if you plan a commercial, closed source app for developing MLRaw files, in which case you have a choice to publish source code or develop your own algorithms. If it's free it's still a good idea to publish your source code as users may chip in and help.

Incidentally, the color specific work we are presently doing for ML will be OS - the aim of this is to get support for MLV in ACES.

Also, as you are not really tied to a specific internal colorspace you should consider using ACES. I'd be happy to assist you with the math for backend transforms but you would have to implement the actual code.

@Andy600 has a valid point about the possibility to try and finalize MLRV since its "nearly completed" and works for both Mac and PC.

However, I also understand @AWPStar's perspective that it may be easier to start from scratch especially if he doesn't know Python.

I just tried running the latest MLVProducer on Windows here at work on their computers and I must admit it does look promising.

Just either try to duplicate as much as possible from MLRV or stick with your original plan. Windows users will be happy on their end.

Thanks for sharing and best of luck!

Very nice indeed. Read something about luts and open color.Not on windows but 1d and 3d lut implementation is always nice. Being able to add maybe three luts on top of each other?

looks promising, nice.

some questions about your code:
 a) is it open source?
 b) does it use any of ML's code?
 c) do you include header files like mlv.h?
a) Why not? But not now. In addition: code in FreeBasic and VB6.
b) No, i haven't used any sources.
c) No. It's my own project. I working on it by myself.
By the way. Can you help me with file format? i know that some people using it.

b)/c) good to hear then

you mean MLV format?
sure, what do you want to know?
No, i meant RAW. Sorry, just missed one word =)
I can not find RAW specification. Need a structure.

structure: [raw image][raw image][raw image][raw image][raw image][raw image]....[raw_info_footer]
Footer at the end? Interesting. Do you you know footer's structure and lenght?
I can get length cause i know frame size.

There's some delimiters between frames?

I got something like:
4 Bytes: RAWM
2 Bytes: Width
2 Bytes: Height
4 Bytes: Frame data size
2 Bytes: Frame's count
some 6 bytes
2 Bytes: Frame rate
....

And frame data size of larger than Raw Data. 2176 extra

What about open source ?
As you may know we highly prefer OS here...
And I think that we don't want to start another "bad plan"...
So your comments about this fact are welcome !
