For this movie, the following settings are activated for the first category, Output:
File Suffix ( .mov ) This adds the .mov extension to all your files. This is necessary if your movies are going to be played on a PC.
Flatten, Cross-platform, Fast start Flatten removes the Macintosh resource fork from your file so that the file can play on a PC, and Fast start enables the playback calculations so that your movie will start playing as soon as enough content has arrived at the player.
Compress Movie Header This function compresses a portion of the movie that the player can automatically decode. I recommend using this for Internet-based movies, but not for CD-ROM or movies stored on hard drives .
