59.94i importing as 29.97p

Question

I have a C100 mkii, in which I have recorded multiple clips at 59.94i AVCHD for slow motion purposes. When I import files into premiere, they are reading/playing back as 29.97. I have tried "Interpreting Footage" to 59.94 but all that does is interpret the footage at 2x speed, instead of true 60i playback.

I tested the camera with all frame rates, 29.97 imports properly, and 23.976 imports properly. It seems to only be an issue with 59.94i AVCHD.

What is the fix for this? I am pretty dissapointed about not having the slow-motion clips available for editing.

The Bitrate setting in the camera is what you need to play with. In some modes you won´t get progressive.

59.94i (interlaced) is not the same thing as shooting 59.94p (progressive). In fact, 59.94i IS 29.97p. So you're not going to get the slowdown potential you would get if you were shooting progressive scan.

Adding in a link here to YouTube to learn about the difference between interlaced and progressive: https://www.youtube.com/results?search_query=interlaced+video+explained

If you want a sort of oversimplified TL;DR, when you are shooting interlaced you're only recording half of an image for every frame. Rather than a full image every frame in the case of progressive. Interlaced is primarily used in broadcast television.
