Most of the timing tab's entries are time-codes. These are expressed as four numbers, as shown in Figure 6.15, “Timecode”.

Timecode

Position is the time at which this piece of content should start within the DCP. In most cases, this will be 0:0:0:0 to make the content start at the beginning of the DCP.

Full length is the length of the piece of content. This can only be set for still-image content: for video or sound content, it is fixed by the nature of the content file. If still-image content is being used you can set the length for which it should be displayed using this control.

Trim from start specifies the amount that should be trimmed from the start of the content. You can set this amount to trim up to the current preview position by clicking Trim up to current position.

Trim from end specifies the amount that should be trimmed from the end of the content. You can set this amount to trim after the current preview position by clicking Trim after to current position.

Play length indicates how long this piece of content will be once the trims have been applied. This will be equal to the full length minus trim-from-start and minus trim-from-end.

Video frame rate specifies the frame rate for still-image content. It can also be used to override the detected frame rate of other content if DCP-o-matic has got it wrong.

Each timecode control has a Set which you should click when you have entered a new value for a timecode. The Set button will make DCP-o-matic take account of any changes to the corresponding timecode.
