Hi Everyone

Would it be possible for you to recommend a M42 -> CANON EOS adapter with working focus confirmation chip for 5D3 (1.1.3) ?
Thanks in advance

Marek

Thanks
Regarding workflow:
- shot with graduaded ND filter and Kinotehnik viewfinder, without any stabilization or tripod
- CDNG generated using MLVFS
- FCPX <> Davinci Resolve Roundtrip
  - Davinci Resolve 12.5: proxy export
  - FCPX: edit
  - Davinci Resolve: grading using CDNG sequences (RCM, Timeline and Output as Log-C), sharpening
  - FCPX: stabilization and little bit of sharpening

I don't know what's wrong but I compiled it also with original code and it works...

I've just compiled it ad now it works like a charm
Thanks !

Thanks for explanation.

How can I force it to analyze every frame ? I don't need real-time playback.

MLVFS caches the correction coefficients so it runs faster. Everything else is the same.

I think that correction coefficients is done in the same way, but "white" is calculated in different way..

@marekk -- Did you forget to refresh the webpage (local host) after changing your options choices?

I've tried it but it doesn't work correctly. I've found that part of the mlvfs code responsible for vertical stripes fixing is the same but procedure to fix is much shorter.

Code Select Expand


void stripes_apply_correction(struct frame_headers * frame_headers, struct stripes_correction * correction, uint16_t * image_data, off_t offset, size_t size)
{
    if(correction == NULL || !correction->correction_needed) return;
    if(frame_headers->rawi_hdr.xRes % 8 != 0) return;
   
    uint16_t black = frame_headers->rawi_hdr.raw_info.black_level;
    uint16_t white = frame_headers->rawi_hdr.raw_info.white_level;
    size_t start = offset % 8;
    for(size_t i = 0; i < size; i++)
    {
        double correction_coeffficient = correction->coeffficients[(i + start) % 8];
        if(correction_coeffficient && image_data[i] > black + 64)
        {
            image_data[i] = (uint16_t)MIN(white, (image_data[i] - black) * correction_coeffficient / FIXP_ONE + black);
        }
    }
}




It removes vertical stripes only from some parts of the dng file. Full code from raw2dng removes all vertical stripes. I shot 256GB of mlv footage (6-10 sec), so I've verified it in a lot of files.
Mlv_dump output is nice but in Davinci Resolve 12.5 is presented as a folder with video and audio file. Correct naming scheme doesn't help. I think that Davinci REsolve is looking for specific tags in DNG file metadata, maybe "Reel Name"..

Hi dmilligan,
Thanks for your hard work with mlvfs.

I'm currently converting mlv footage from my holidays trip to dng sequences and I've found that vertical stripes fix doesn't work. I've tested it with mlv_dump and it works fine. Is it possible for you to implement full vertical stripes fix from original raw2dng code ? I've found your fix code is different than raw2dng..

Thanks in advance

Thanks,
.. but it's a guide for DR 11. In v12 we need to set "Color science" and then "Timeline colorspace".. As far as I understand we don't work with RCM so "Color science" should be set to "Davinci YRGB"?... But what's with Timeline colorspace ?

How to setup Davinci Resolve 12 to export cinelog prores files? (I've got the lut package)

Hi Andy600,
Could you please specify what options are currently considered as "best settings" for Davinci Resolve 12 to:
1) open and edit ML DNG files directly in Davinci Resolve end export final movie in Rec.709 2.4
2) export ML DNG sequences as prores files in some universal log format, for example Arri Log C

I'm looking for correct settings for:
Color science, Input Colorspace, Timeline Colorspace, Output Colorspace, Lookup tables (with full Cinelog Lut names).

Thanks in advance

hmm 1920x1080p 50fps without any stretching ?

Awesome work !!!
Could you please share your method of shooting at 50p ?

Hi.. I'm working on my new timelapse project and I'm looking for best way to remove objects (people, cars etc) from single frames... I would like to create some mask and fill it with contents of next or previous frame. I can't find any tutorial.. please help

In current version there is an option to preload some frames. When I add all MLV files to Resolve timeline for grading and exporting to prores current CDNG is played smoothly. At the beginning of next file there is a 1-2 seconds period of interruption. So.. when MLVFS is currently working with FILE_1.MLV, we can preload some frames from FILE_2.MLV. Switch from FILE_1.MLV to FILE_2.MLV can be done smoothly. It will work only if files in timeline are sorted by name.

@dmilligan - is there a possibility to add option to preload some number of frames not only from current file but also from next available file ?

I didn't know there was a problem with switching from 1.1.3 to 1.2.3. I'm using fresh builds for 1.2.3 from the beginning without any issues. I'm using mlv_rec mostly..

It's only autoexec.bin with modules.. It's not a full ML package.

Full package is available here:

dmiligan - thanks for the hint

#define FORMAT_BTN "[Q]"
#define STR_LOC 13

should be replaced with

#define FORMAT_BTN_NAME "[Q]"
#define FORMAT_BTN BGMT_Q
#define FORMAT_STR_LOC 13

Hi
I'm trying to build 5D3 1.2.3 but I'm receiving this error:

My last successful build was at the beginning of January. I didn't change anything with my compilers. I've found one conflict with src/bootflags.c in 5d3-123 branch but it's not related to this error.. Is there something new in ML?.. I'm using gcc-arm-none-eabi-4_8-2013q4 . Should I upgrade something ?

Hi Andy600.. I've got one question regarding Cinelog-C workflow. I would like to make timelapse video but single frame will be a merge of 3 images (luminosity masks). Then I would like to export final frame to TIFF. I would like to export final sequence to prores 4444 Cinelog-C. Is there a possibility to convert sRGB to Cinelog-C ? What color profile should I choose in Lightroom ? Standard or Neutral ? I would like to correct only a white balance in Ligtroom and maybe some lens settings..

How did you set resolution in mlv_rec properties ? It was 1920x ??

I applied my standard powergrade for sharpening in Resolve.. hmm.. next time I'm going to change something a little bit

Workflow:
mlv2dng -> Resolve -> BMDFilm - Cinelog C -> Grading -> Prores 4444 -> FCPX
