After I download the 79MB mp4 video from the link in the bottom right corner of

which ends up being "85989774_c7d332975b_orig.mp4" on my computer, and add it to a new FCP project, there are a few problems.

Firstly I cannot use 'Item Properties->Format' to start SmoothCam analysis on the clip. No pop-up appears.
Secondly after adding it to a new sequence (after the do you want to change settings of this sequence to match the clip), I get this

...followed by the 'Out of Memory' error.

When opened in QuickTime Player, it cannot determine the data size.

I won't advise editing off any of the mpeg formats at all (or run smoothcam on them). You should convert them to an editable codec in Compressor/Mpeg Streamclip

Mpeg has always been sketchy in FCP. I had an Mpeg break up into a patches of green frames recently when i tried to render it in a video (i just wanted a quick sample for the client, so a still was more than sufficient).
