You can add a timewarp to a clip to convert it to a different standard frame rate. For example, if you are working with PAL clips and have a few NTSC clips, you can convert them to 25 fps so that their frame rate conforms with the rest of your clips.

To convert a clip to an alternative standard frame rate:

1. Display the timeline for the clip.
2. Select the segment. If the clip has audio tracks associated with it, select all the tracks.
3. Press Ctrl+T to create a timewarp.
4. Change the speed percentage according to the following table.

   For this frame rate conversion:	Use this speed percentage:
   PAL to NTSC	120%
   PAL to 24p	96%
   NTSC to PAL	83.33%
   NTSC to24p	80%
   24p to NTSC	125%
   24p to PAL	104.17%

   NoteThe other timewarp parameters should use the default values, namely: Mix - 0.00, Timewarp Type - Constant Speed, Sample Options - Sample Middle, Render Type - Interlaced, No Interpolation.
5. Process the timewarp.
