Summary: The Adobe Premiere Pro won't import H.264 files smoothly. The easy workaround is to transcode H.264 to a more "edit" friendly codec for Premiere Pro. Here is how.
I've had huge problems with h.264 and Adobe Premiere Pro. I shoot with a canon T2i at 24fps and its native video is on h.264 codec. I used to edit by importing the native H.264 footage into Premier Pro (CS6), but found trouble when it was really slow and didn't flow smoothly. Searching from Google and got some recommended solutions for using H.264 files in Adobe Premiere Pro. Below is the test of these ways.
Solution 1: Try MPEG Streamclip to encode h.264 to quicktime
I read some threads about encoding h.264 into .mov(I don't use a Mac so ProRes is not an option) so I heard of the program MPEG Streamclip 5 Squared to convert my videos and export them as a Quicktime. However, when I import the videos with this new codec and try to edit it, it still lags and it's annoying to edit.
Solution 2: Try Brorsoft Video Converter for Mac to convert H.264 to MPEG-2
