I have tried both methods AMA/transcode and importing in a 29.97 project (dnx45). Both show incredibly long render times.
I’m currently transcoding in a 23.98 project, and the wait time is much better. 5hrs for a 4hr duration, instead of 88hrs for a 4hr file. I don’t understand why there is such a difference and if anything the 23.98 transcode should take longer since its doing the frame rate conversion.
