Apple
Intermediate
Codec) A video format from Apple that was developed for editing HDV and AVCHD movies, both of which use interframe coding. When HDV and AVCHD footage is converted to AIC, the interframe groups are turned back into individual frames for ease of editing. The AIC format increases file size dramatically but is less demanding on the CPU while editing. See
