# The Change Frame Code Mode Tool

The Change Frame Code Mode tool allows you to change the framerate and drop frame mode of a clip, but also deletes any Deliverable attached to it. The Change Frame Code Mode tool can be accessed as follows:

- In the clip library, from the Tools box, via the Change TC/KC option, when you select Timecode and New TC Mode (or New Start & Mode).

The Change Frame Code Mode tool options are described as follows. Only those options that are unique to Frame Code Mode and not already described for Timecode are included here.

Same Start TC/Frame box
  Select a start option. The Same Start TC/Frame box is active only when New TC Mode is enabled.

Select: | To:
--- | ---
Same Start TC | Start with the same timecode as the one used in the old mode.
Same Start Frame | Start with the timecode that matches the corresponding timecode in the new mode—calculated by the number of frames that correspond to the original timecode, starting from 00:00:00;00.

Frame Code Mode box
  Select the framerate and drop frame mode for the selected clips. The Frame Code Mode box is enabled only when the Change option box is set to New Start & Mode or New TC Mode.

24 fps | 24 frames per second timecode. Used to transfer a video signal to film. | 00:00:00+00
25 fps | 25 frames per second timecode. Good for LCD monitors or display formats that are not interlaced. | 00:00:00:00
29.97 fps NDF | 29.97 frames per second Non-Drop Frame timecode (frame rate for colour NTSC). If you use 29.97 fps NDF, its indicated timings will not accurately correspond with real time. | 00:00:00:00
