Timecode Overlay

nablet Support Team

To add a timecode overlay to the processed video, you should use modify the video filter parameters of your encoding preset - the [VideoFilterSettings] part. This part includes some other filters like Teletrax watermarking, but all the unused filters can be skipped.

Here is an example of how the section might look like:

[VideoFilterSettings]
EnableTimecodeEmbedding=0
KeepFirstStartTimecode=0
TimecodeSetStartTime=900000 
TimecodeHorzPosition=right 
TimecodeVertPosition=bottom 
TimecodeXScale=1.0 
TimecodeYScale=1.0 
TimecodeFormat=Frames

The parameters are:

  • EnableTimecodeEmbedding - enables the timecode overlay (0 means "off", 1 means to add a timecode overlay into the video)
  • KeepFirstStartTimecode - once enabled, the engine uses the start timecode of the source file for the first processed frame. Works only if the start timecode information is available in the source and the TimecodeSetStartTime is not set.
  • TimecodeSetStartTime - forces the engine to use this start timecode. The value is a number of a frame that is recalculated to a timecode and used as the start timecode value for the resulting file.
  • TimecodeHorzPosition - sets a horizontal position of the overlay.
    Possible values are: default, left, middle, right.
  • TimecodeVertPosition - sets a vertical position of the overlay.
    Possible values are: default, top, center, bottom.
  • TimecodeXScale - the overlay horizontal scaling. The default value is 1.0. 
  • TimecodeYScale - the overlay vertical scaling. The default value is 1.0.
  • TimecodeFormat - the timecode format.
    Possible values are:
    • Default - use the default timecode format
    • Time - timecode and milliseconds, e.g '10:00:01,832'
    • TimeAndFrames - timecode and frames, e.g '10:00:01,24'
    • Seconds - seconds, e.g '23,294'
    • Frames - absolute frames, e.g. '1201,000'
    • SMPTE-EBU-25 - SMPTE 25 EBU (25 fps, Video)
    • SMPTE-Drop - SMPTE Drop Frame (29.97 fps, Video)
    • SMPTE-Non-Drop - SMPTE Non-Drop Frame (29.97 fps, Video)
    • SMPTE-30 - SMPTE 30 (30 fps, Audio)
    • SMPTE-Film-24 - SMPTE Film Sync (24 fps, Film)
    • SMPTE-Film-IVTC - SMPTE Film Sync IVTC (23.976 fps, Video)
