I have graded a 1080i 29.97 music video using ProRes transcoded files from AVCHD camera originals. All ProRes source files are 1080i @ 29.97fps. Grading went very well but when setting up the Deliver Page for export, the only frame rate options are 23.976 or 24. Am I missing something with the export frame rate? I need to export a ProRes master file at 29.97fps. Thanks for clues in advance!

Sounds like you had the incorrect project setting when you conformed. Unfortunately you can't fix it now. What you need to do is create a new project. Before bringing in any media, check your project settings. Then reconform your cut and use the colortrace function to copy over your grades.

Blackmagic REALLY needs to change that..
There is no logical explanation why one should be locked into a fps speed.
In Scratch it just plays and renders on whatever you set it, and Smoke even has a re-conform feature that lets you change the speed and adjust all the editing.
Ia m not asking for something like that, but we need to be able to change the speed, or at least have an automatic rebuild function.
Please :)

There is one logical reason, which is that fps effects the conform tc. That said the "handle mixed frame rates" option avoids this, by just rendering at the source fps. So that the conform less important.

Had a similar issue on a 2 hour doc full of mixed frame rate media. Imported Final Cut 7 XML. The 29.97 sequence was interpreted as 23.98 in resolve. I assumed it was simply removing the pulldown so I didn't alter the sequence. Render to 29.97 was grayed out.

We were pressed for time and rather than chance it with colortrace, I used cinema tools to change the frame rate of the rendered output from resolve.

Everything seems to be fine. Looks good and plays back in sync. Was that a bad idea? Am I unreasonably mistrustful of colortrace?

I'm more distrustful of mixed format conforms than I am of color trace. For whatever that's worth.

Colortrace has not failed me yet.

Apple COLOR was like this with the initial project settings framerate. Frankly I don't think about it all that much as about 99.9% of all projects are XML/AAF flow -- settings automatic.

That you do ned to set an initial framerate I think stems from Resolve's origins as a tape-to-tape and dpx processor, where on the one hand, the framerate was a hardware issue, and dpx file sequences have no intrinsic framerate, like film. Its just a frame. How many of them you want to display per second is up to you.
