H.264, 1280 × 720, 59.94 fps to FCE

Question

I want to bring a file with these characteristics into FCE for editing:
*Video Tracks:*
*H.264, 1280 × 720, 59.94 fps, 6.22 Mbps*
*Audio Tracks:*
*MPEG-4 Audio stereo, 48 kHz, 128 kbps*
I read many posts and I understand I must convert it to a format FCE can deal with. I used Streamclip to convert it to a file with these characteristics:
*Video Tracks:*
*Apple Intermediate Codec, 1280 × 720, 59.94 fps, 99.38 Mbps*
*Audio Tracks:*
*16-bit Big Endian stereo, 48 kHz, 1.54 Mbps*
Now, the question becomes what preset to use in FCE to work with that file.
There is no obvious "Apple Intermediate Codec, 1280 × 720, 59.94 fps" preset in Easy Setup. So, I picked:
*HDV-Apple Intermediate Codec 720p30*
And, for some reason, this seems to work fine. How is that right? Can this 720p30 preset actually handle 59.94 fps materials?
As a side note, if I transcode the original file to a file with these characteristics:
*Video Tracks:*
*Apple Intermediate Codec, 1280 × 720, 29.97 fps, 99.38 Mbps*
*Audio Tracks:*
*16-bit Big Endian stereo, 48 kHz, 1.54 Mbps*
And import that in FCE, the video then appears to play in slow motion in FCE. (and audio sync is lost too)
It must be a stupid question, but I find this confusing a little.

Answer 1

The QuickTime movie inspector says the same thing Streamclip does. (see previous post)
I just did a new transcoding of the original clip using Adobe Media Encoder CS5. The characteristics of the output file are:
*Video Tracks:*
*Apple Intermediate Codec, 1280 × 720, 29.97 fps, 49.86 Mbps*
*Audio Tracks:*
*16-bit Little Endian stereo, 48 kHz, 1.54 Mbps*
I imported this file in FCE and that works fine.
I am starting the believe FCE behaves differently at different times of the day.
So, I am going to transcode again using:
1) Streamclip (whose interface is confusing, since it's hard to tell if the settings on the main window override the settings you set via the "Options..." button near the selected codec)
2) QuickTime 7 Pro
3) Adobe Media Encoder CS5
Those 3 tools expose codec options in slightly different ways, which certainly adds to the confusion.
As far as Apple Intermediate Codec is concerned, under QuickTime Pro, for "Compressor", I can pick HDV 720p, HDV 1080i, HDV 1080p or Other. "Other" is selected by default so I left it to that, even though "HDV 720p" looks more like the FCE "Easy Setup..." preset.
