BMD Camera DNG Folders

Our production house just got our BMD Camera and shot some sample footage in RAW. I transferred the data on the SSD to our SAN. However, while trying to bring the media into Davinci Resolve Lite, only two of the DNG sequences show up as unified clips. The other 25 'clips' show as the DNG folder with the sequences inside, but not as unified clips. Any ideas on why the media is not displaying correctly like the two clips?

Difficult to tell from the screen shot but from one of my recent shoots Resolve did a similar thing on clips that had dropped frames.

All the folders that had takes that were complete appeared at clips in Resolve. The 2 takes that had dropped frames appeared as folders that then contained clips (from each part either side of the dropped frames).

Interesting. I was not on the shoot, but is there an in-camera indication of the dropped-frames? But this does seem like a likely explanation of what might be going on. Thanks for your input Adam.

Also, putting the SSD (Kingston 120) back into the camera, the clips are all there and play back normal.

If the clips have sequential number in the filenames, maybe you could look at a folder in the finder, and subtract the first from the last, to compare to the total item count to see if any frames are missing.

This has happened to me when I dropped frames two or three times since November. In my experience it always is a sign of dropped frames.

Cameras Rec indicator flashes in the status bar when you have dropped frames. The sequences will still play fine on the camera.

I'd not shoot RAW on anything but the SanDisk 480GB.

Smaller SSDs tend to be slower anyway.

Thanks for the input everyone. Looks like I may have to deal with getting some new SSDs to remedy this situation. I guess I can convert the DNG sequences for now, but a little sad that the native RAW files may not operate in Resolve as I had planned.

You can "fix" the RAW sequences.

Open the folders and look for the missing frames. They are sequentially numbered. If its just a single frame you could duplicate the frame before and rename it to complete the numerical sequences.

Resolve should now read the clips just fine.

Yes the playback will appear to stutter at that point as it "pauses" for 1/24th of a second (for 24p) but it'll do if you can't reshoot.

Hi, I am having the same issue! I have over 70 folders containing dng pictures (Shot in 2.5k RAW at 24p) and only 15 folders are showing up in Davinci Resolve Lite. Is dropped frames the only reason for this issue? As I have gone through and checked and could not find any dropped frames... Would very much appreciate some help on this one!

Thanks,
Sam
