After Effects is a large complicated piece of software which 99% of students will have no use for. However, one simple job that it does well is converting your footage into slow motion sequences. I would recommend this process for achieving high quality slow motion.
1. Shoot your footage in 720P60 on the Canon T3i camera.
2. Use the folowing tutorial to slow down your footage. Export as Quicktime with the animation codec.
3. Import your footage in your editing program (Premiere, Avid, FCP, etc).
