File Naming Examples

For textless or other versioned inserts, reel numbering and frame numbering of textless should match the texted sections, and be provided with 3 frames of handle on either side of each textless shot.

Textless main titles and end credits do not require a distinct file naming convention.  Each textless insert will reside in a unique folder but the base sequence file names should be the same. 

Filenames should include the same information as folders above, separated by underscores:

ProjectTitle_EpisodeReel_DeliverableName_DynamicRange_ColorSpace_CreationDate_Resolution

Framing Charts

A framing chart image must be delivered to define the mapping from camera source resolution to final presentation resolution.  Specific requirements are listed below:

  • A unique framing chart should be supplied for each camera with a unique capture resolution.
  • Framing charts should be supplied at the original camera capture resolution. 

 


 

LUTs

All LUTs must be delivered in .cube format; we have no requirement for LUT dimensions.

File Naming

For a LUT to be useful, it is important that its file name be descriptive as to its application.  It must be easy to understand at a glance.
