timecodecalc

Initial release v1.1a (2/13/2009) by The Lightning Stalker (SourceForge)

This will take a CellTimes.txt file and output an NTSC-ND timecode for each "Cell Time" for programs such as Scenarist.

This program was brought about as a way of translating video time positions between video editing and DVD authoring suites which tend to use one type of timecode exclusively. If you've authored your own DVDs with Scenarist then you already know what a pain it can be to get the chapter positions (scenes) in the right places. It is hoped that through a great deal of my frustration, this will relieve some of your frustration.

BTW, this is my first C program. Not bad, eh?

Build Instructions

Linux:
Simply execute `make` in the source directory

Convert movie time position information from one format to another, as read from INFILE, and send the results to OUTFILE, or standard output.

Options

  -r, --framerate=FPS      frames per second, required

One, and only one, of the following is required:-

  --f2n                convert frame numbers to non-drop timecodes
  --frames2nondrop     ...
  --n2f                convert non-drop timecodes to frame numbers
  --nondrop2frames     ...

Examples

timecodecalc -r30 --f2n CellTimes.txt

Read frame numbers from CellTimes.txt and output non-drop timecodes to standard output based on a 30 frames per second model. (NTSC)
