60 fps workflow

Hi, with all the new Nikon coming with 1080p 60 fps, I wanted to know what would be the work-flow if you want to transcode the codec. I have been using Davinci resolve and I see that transcoding to Dnxhd or Prores gave you better performance than the native codec. But the problem is that I cannot find any software to transcode the 60 fps into to those two on PC.

For example using the popular mpeg streamclip you don't have any 1080p 60fps Dnxhd settings. Everything is only 60i. I want to be able to transcode and use the shot at 24 fps for slowmotion purpose.
 
why not dropping the native-codec-footage in your NLE, set the speed for each clip you to 40%, export a FCP XML, import into resolve and then export the timeline as ProRes/DNxHD 24p, as individual clips... That way you would get the clips already retimed for slowmotion. Tick the "export audio" box if you need it, so you could speed up the footage by factor 2,5 and still have normal speed footage with recorded audio if needed. hope that makes sense.
 
Hi Stefan, I was thinking more using Davinci as my main editing software as the editing side is enough for my needs. being able to edit, garde and finish in the same app is very compelling. More so that Blackmagic has just launched a free and much cheaper version of Fusion for vfx work and we could find ourself with a very powerful post workflow in the near future. From my test of resolve for now is that the use of codec like prores/dnxhd does make a difference in speed when you have numerous node. I cannot say for sure that the converted dnxhd or prores files that I have processed (24p files) are more solid that their native file. That is why I was hopeful for a 60p workflow
 
you could still apply the "import-retime-export-import again" procedure and see how it works for you. i think that editing will be a bit less stressful for your machine, but i can't imagine that your footage is going to hold up better while grading. a heavily compressed file will always be "crap" to some degree, you won't be able to make it better just by doubling its size.
 
Apple's Cinema Tools was the gold standard for this - launch, choose a folder, choose a frame rate. The footage isn't re-rendered or duplicated - just the data that says "play the frames at this rate" is modified.

I'm amazed nobody has stepped up and written something that simple, fast, and efficient.

Anyway - one workaround is after effects - import footage, choose "interpret" and set the frame rate (for each damn clip, yeah). Drop onto the comp icon, and drag the comp to the render queue, choose "Prores" and let it run.

Yep, you get a 2nd copy of your footage, and if you have a hundred clips it kind of sucks to set up. I keep an older laptop with cinema tools, and have a boot disk on my mac pro with an older OS and cinema tools as well. However, CT won't work on many newer codecs.
