Codec (Code and Decode)

Lucas Film wanted to create a digital compressed file format in the 90’s.

Cinepak was a company who would code and decode (make a file you could create)

H.265 – Lucas film created H.265 (Small file sizes with very good resolution) – You can burn it to a CD/DVD and YouTube.

Lossy compression means you cannot return to the original file.

My teaser trailer will feature lots of drama to add suspense when it features the howl of a wolf at the end during the interview with suspenseful and tense music, building up gradually to the howl at the end. The screen will fade to black at the end and have titles on some clips which have rhetorical questions like “Will she get out alive?” and things.
