Should I convert mp4 before editing in Premiere CC?

I am editing mp4 video files recorded from my Playstation 4. They are mp4, avc coding. When I import them into the timeline, the bar is red so I have to render just to play back. Is this typical? Doesn't seem like an efficient workflow. Or should I convert them to an uncompressed type of file beforehand?

Yes, you have the right idea. Perhaps not "uncompressed" but some kind of "intermediate" intraframe codec, like ProRes or Cineform. You can use Media Encoder to do the conversion. You can also create proxies for a smoother workflow.

True, it is more convenient editing the original files, and Adobe touts its native file workflow with Premiere, but most pro editors convert the footage to an intermediate codec or create proxies for a smoother editing experience. I do.

Those are probably long-GOP, and perhaps VFR ... variable frame rate ... also. Both add to the 'overhead' for playback within PrPro.

Which means the system you're working on and the disc the media is living on are both rather important ... so details on your system would be very useful. You can of course go to the right lower corner of the Program monitor, and set playback resolution to 1/2 or 1/4 to improve playback some. Or make proxies.

And ... please drag/drop the media onto MediaInfo on your desktop, go into that app's TreeView, and drag/drop the video info section into your reply. Then we'll know exactly what is in that media of yours.
