I've implemented a very experimental dual ISO conversion (I really prefer to think of it more as a preview). It's nowhere near the quality of cr2hdr and probably not all that useable for real work yet, but it's realtime...

Where can we try this out? Thanks for providing this to us.

Hi David. A realtime viewer on dual iso moviefiles. Not bad at all! Mlvfs should be in camera as well ;).
I did a fast comparison between cr2hdr and mlvfs. Don,t know if it,s relevant. Just two original dng;s and then applied the same settings lifting shadows and such.
I provide the dng;s in two links. Also linking to the original mlv file (about 350mb) if anyone wants to play around.
Off to work then.

Download links are in the first post. Mac version has been updated, ayshih will need to update the Windows version.

@escho: The Makefile had not been updated for compilation on Linux.  Try again now.

ayshih will need to update the Windows version.
The Windows/PFM version of MLVFS now has the same (experimental) dual ISO support.

Wow. Just like that :). Confirmed working. Tested on mac binary cr2hdr20bit. This would be a killer now with kitchehof lightroom plugin.
Can I ask you of a terminal command. Lets say I want to convert a bunch of dual iso folder and use some drag and drop command to terminal instead of selecting all files within folders and dragging those to terminal window. I tried a little with recursive command but I really don,t get it.

For now I 1) drag cr2hdr20bit to terminal 2) enter the folder, selects all pictures, drag those to terminal 3) enter.
What I like is able to select all folders and drag those to terminal.
Thanks David!

You can use 'find' and 'xargs' to recurse into subdirectories:

find /path/to/parent/directory -name '*.dng' | xargs /path/to/cr2hdr --any-cr2hdr-options-here

This will convert all dngs anywhere inside /path/to/parent/directory. Is that what you're looking for?

Thanks a lot, gonna check into this later tonight.
Dual iso conversion is a breeze now since you fixed exiftool. Great work.

Awesome!! With your script command I,m only one click away now. Created a bashscript to a folder I will use on my desktop. Thank you a lot. Most grateful.

hello,
i really like the idea and workflow of this tool, but have just realized, that the free version of davinci resolve 11 has no hot cold pixel correction for raw files (as far as i know). so i wonder if  - hot/cold pixel correction will be possilbe in the near future?
i ask because i had a video shoot the other day, where i recognized a bad pixel in the middle of the screen and it is really annoying.

thank you for your time and engagenment. greets. swinxx

bad pixel correction is implemented, please test

it's kinda slow (~2fps on my machine), IDK if there's much way around that, there's a couple more possible optimizations, but I doubt it will ever be realtime

thank you dmilligan, i will test it at the weekend, you are great!
that should help a lot!
so i see a seperate bad pix script, is there chroma smoothing and/or dual iso implemented too?

btw.. i was download number 1 :))

Yes, chroma smoothing is implemented. There is also a dual ISO "preview", quality is not very good. It will run if you have "DUAL" in the path name.

Well, there were getting to be too many options, and I wanted there to be a way to turn them off and on without restarting mlvfs. So I have embedded a little webserver (mongoose) in mlvfs for configuring options at runtime (this also eliminates the need for all those different automator workflows). The new mac workflow will automatically popup the configuration page in the web browser when you start it. You can always get to it at http://localhost:8000 when mlvfs is running. This will be a great help in the future as options start to proliferate, it also may be useful for displaying status/error information.

@ayshih, mongoose should work on windows, but this may not be as useful since you have to multiple instances (and the webservers would conflict), so you may want to simply disable this with macros

Hi dmilligan!

i have tried the new badpixel option, but here in my specific shot my bad pixel is not gone.
so i see no difference in on and off position.
 
please take a look here:
https://copy.com/LjWpLtXeqIrO0AtK

should i contact a1ex, or is my problem not a bad pixel?

thank you very much..

That pixel doesn't appear to be bad enough to trigger correction based on the current algorithm, because I've assumed a value for dark noise rather than calculating it (for speed), and this pixel was just barely below that threshold (so the algorithm basically thinks it's dark noise, not a hot pixel). The threshold was conservatively high, so I'll lower it a little. Thanks for the feedback.
