Are there any other rates you'd like to see added that aren't currently there (e.g. 59.94 DF)?
For that which applies to me directly, just 23.976 is fine just for now, simply because I haven't needed to use workflows requiring other framerates.
I had a brief look at these links:
and I see there are other possibilities, especially given that film makers like James Cameron and Peter Jackson will likely carve new post pathways in the near future. Adobe Audition is certainly the swiss-army knife of audio applications and it would be a shame for it to be limited by frame rate options.
So whether that means add some known ones now (59.94 is probably a good addition to have) and others in the future as they become standard, OR whether it means having a more solid way of dynamically allocating frame rates with customization, is something to be worked out, but addressing a known and often used rate like 23.976 is probably the way forward for now.
Thanks for addressing this.
