I am editing a music video and after I rendered the workspace, I began previewing the video...
In several places the video has become very choppy, skipping frames or something. How do I fix this? Should I play around with playback timing or fps? No clue what to do..
Any help is much appreciated!

The first thing you have to do is to determine whether the choppiness is due to a bad source (your camera skipped some frames) or an inadequate playback system (your editor is demanding more from your hardware (most likely disk subsystem or GPU) than it can provide). To do this, render out a small version of the video (such as 360p) and see whether that plays back with or without glitches. If the render has glitches, you have a bad source file and fixing it will be very hard to do. If that render plays back without glitches, the problem is likely that your hardware is not powerful enough to edit video as is. In that case, you can try editing proxies, which are basically smaller versions of your original files. Once you have all the edit decisions made, you can render out a full-res version. But it still may not play back without glitches unless you have a good disk subsystem and a sufficiently powerful CPU/GPU.
To test the speed of your hard drive system (and to see what video specs it can support without glitching), run the Blackmagic Design Disk Speed Test (if you have a Mac): https://itunes.apple.com/us/app/blackmagic-disk-speed-test/id425264550?mt=12 . Or equivalent if you don't.
