Encoding

Picture track

Please only provide fully checked source material.

Uncompressed file sequence (*.dpx, *.tiff) are accepted. It is mandatory that no compression, even lossless compression is applied to the file sequence. Please check the files’ size (MB) in the file folder, all frames size should be identical. These frames have to be provided on Windows NTFS formatted hard disk. A Macintosh volume would slow down the DCP creation process. Frames can be split into reels such as with film, with a different folder on the hard disk from each reel..
An alternative to the file based delivery is providing a single uncompressed video (eg. QuickTime MOV uncompressed). By the way, this solution presents some disadvantages: resolution limitation, one large file to handle, If the only available source material is a compressed video file, which is not recommended, it is crucial to check the compression ratio has been properly adjusted in order to preserve a sufficiently decent quality. Accepted formats are: QuickTime MOV, Apple ProRes, MPEG,. Highest quality recommended (bitrate and resolution).

Progressive pictures are recommended as opposed to interlaced pictures as the de-interlacing process would have to take place on each eye separately which could lead to small differences between the eyes.
