Post-production is the final stage of the production process, often referred to simply as "post." During post-production, all the footage captured during production is edited and assembled into the final product. Post-production includes: editing video footage, editing and adding music and sound effects, adding titles and graphics, color and exposure correction, adding special effects, and reshooting "pick up" shots, if necessary.
If you have been filming using different devices, you will have to collect all this footage onto one device for editing. Creating back-ups of your footage may be a good idea as well, especially for large projects.
