Well done! I didn’t know Lightroom has that feature.

Now I believe Resolve 10 beta lite (newly available) allows for higher resolution delivery (output) than 1080p, so you may now be able to output higher res for web.

While I believe even Vimeo Pro only allows 1080p, I think youtube allows far more, and while you have to put up with their compression. The resolution will likely shine though.

If you put up any high res footage, please share it with us.

In the intervening time since the last posts, I heard news that Resolve has been updated to handle sequential DNG’s and should handle those in the same folder as a movie clip. I never got this to work myself as yet, but now for those without Lightroom or those wishing to use free products, using Adobe free Raw2Dng converter should prepare clips for Resolve. The only workflow I managed was via sequential tiff’s into Resolve, using Nikon ViewNX.

If only Nikon V1 allowed 6-7 seconds of raw 🙂

see previous post also!

I wondered about the structure of DNG files and if I could potentially alter the embedded recorded res size of the thumbnail (to say 4500 x 4500) it might trick Resolve into seeing the thumbnail res as larger than the V1 raw res of 3872 x 2592, then the raw res would be the smallest, so Resolve might use that raw image instead.

I could use a hex editor directly on the binary DNG file, but would need to find out which part of the file the thumbnail res info might reside, and if the thumbnail res info exists in addition to the actual pixel data of the thumbnail.

I have located a hex editor that records macros and performs batch operations so in theory would do a whole directory of images in one go Hoping to make progress but would appreciate any help in making sense of DNG file binary strucure!!

It appears that after converting my NEF files from my V1, Adobe DNG converter inserts a thumbnail into the DNG file. The thumbnail has been verified as 256×171 by a colorist in California, hence why the footage resolve shows is this measly res.

Although Davinci Resolve has been said by their support people not to support a directory of seqential DNG files, Resolve does actually play the clip, perform grading, even outputs the results “deliver”, however they are unfortunately correct in saying to me on blackmagic forum that Resolve defaults to the lowest resolution image in each DNG file when dealing with sequential DNG images.

My conclusion, is that if we find a way to convert from NEF to DNG file without having the thumbnail embedded, or find a utility to remove the thumbnail after conversion, then we could have our cake and eat it!

I have since batch converted the NEF sequence to TIFF and Resolve imports that at full resolution which is better than no import at all, but all the same I’m disappointed not to be able to have graded 4k RAW files for such a small outlay even though the subject might usually be my grand daughter!

Got this helpful reply from Blackmagic support on their forum:

Resolve only supports CinemaDNG files.

Standard DNG files have multiresolution support, and if you put one of those in Resolve, it will usually see and report the lowest resolution. Resolve does not support those.

Hello Paul,
Following is copied from a post I just made on EOSHD:
———————————————-
I just took delivery of a Nikon V1 which does 30 frames of 4K raw storing each as Nikon NEF files using it’s electronic shutter.

I used Adobe DNG Converter to convert all 30 frames into a sequence of 30 DNG files.

CinemaDNG can exist as a sequentially numbered sequence of DNG files in a directory. To prove this I downloaded the Autumn1 files from https://www.ikonoskop.com/workflow/
and it load into Resolve 9 lite without problem and shows the correct resolution of 2048×1092-16b and of course looks great. I notice that Each AND EVERY DNG file is 3,288KB.

Interestingly when I look at the file size of my Nikon NEF files they are all slightly different sizes but all close to 10,300KB. After converting using Adobe DNG Converter, Each file is again slightly different size but all are about 11,700KB. Maybe I have answered my own question, but how to convert my NEF files to a consistent DNG sequence?

Here is an example of a V1 Sequence, using RAW files, but using tools other than Resolve ;-(

I can’t wait to overcome whatever problem I have to get the Nikon output into Resolve!!

I’m having the same problem when I use a sequence of DNG files, resolve only brings in low 256×171 frames when the dng resolution is 3872 x 2592 pixels.

Help please!
