Video editing

I have about 90 minutes of video, (two people talking, static camera) that I would like editing into 10 short clips (average 5 mins each) that are going to be posted on an online course website.

I would like to add titles to each video and explore adding a few illustrative graphics. The sound was recorded on a separate recorder and I have synced to the video using Premiere Pro but it could do with a bit of work on the levels in some parts. It is for use in an online course so production values do not have to be very high, just needs to be neat and have consistent audio levels.

you can see some of the video on this Youtube link - https://youtu.be/OR-sTClopRo
