I think I made the correct changes from what Alex said, here are the 4 versions plus the normal one. Like always make sure the file is in the same folder as the EXE file when you drag and drop to convert.

mk11174, thanks a lot. I could convert successfully half of missing frames, but still on the rest there is some interlacing, I don't know why.
Before conversion:

(It's a still from the shot of throwing molotov cocktail)

I've compiled 4 different version of cr2hdr with the combinations quoted.

Many thanks, Audionut. Unfortunately when I drop dng on cr2hdr I got a message that version of this file is not compatible with my windows version. I got win7 64x. What version I shoud have?

Thanks Alex. How exactly I can use this code? Cr2hdr closes immediately after double-click. Where should I write the code and filename? Sorry for asking banal questions.

Give them some time, will you? Unless someone says it *won't* be implemented, given the amount of features being worked on in parallel and this not being a major bug it's not on top of the list... look again after a week or so?

I know, I keep asking cause tomorrow I got an exam in filmschool and one shot in my exam movie is missed...

...so no developers interested in modification of cr2hdr to have manual control instead of automatic detection of fields order? Maybe easier than implementing command line would be 4 versions of cr2hdr, since there is 4 combination of fields order?

But it would teach you how to use photoshop actions :->

I know actions. Resulted images from photoshop are awful. Aliasing is much worse than from cr2hdr converted at half res. HDR merge doesn't work as it should too.

A command-line option may help if you are willing to process each shot manually and fiddle with the offset until you get it right (I'm not). There are 4 values that you have to try.

I'm begging for a patch. Everything would be better than cutting and pasting 2 pixel lines in photoshop on 50 frames . Please!

It requires the automatic recognizing to know which fields are bright and which are dark. This varies from camera to camera and sometimes from frame to frame.

Can you upload another CR2?

Thanks for explanation. In attached images fields are changing from frame to frame. Maybe a command of indication if the top field is bright or dark would rescue them?

I'm still trying to rescue my shot, since not all of the frames converted. Cr2hdr failed on low key shots. Alex, would it be possible to create a version of cr2hdr without automated recognizing interlace, which extract just one iso channel, at half res, just to get rid of interlacing on unconvertable images?

maybe you can upload the two cr2 for some one to analyze.

If somebody is able to convert second file, let me know, please.

Well, if you really want to remove the error checks, feel free to do so, but you'll get just garbage.

Hint: I can't troubleshoot anything from these logs (other than reaching the above conclusion).

I attached these logs just to show where it stuck. I have no programming skills, I simply thought that maybe it's a matter of tolerance in ISO difference estimating process. Is it possible to do the conversion in photoshop? Any idea?

I got a problem with conversion from interlaced dual iso dng to normal dng. I shot fire in the dark with fps override to 65 fps. Brighter shots are converted correct, but darker aren't recognized as interlaced. Even in the same take one (brighter) frame is recognized well...

Is there a way to force cr2hdr.exe to convert dngs or other method than cr2hdr.exe?
Please, help. This footage is extremely important to me.

Camera: 5DM3
tried different versions of cr2hdr.exe
