Change speed and FPS without manipulating frames

If you want the final output file to have no duplicate/repeated frames, then you will have to create a file with a frame rate of 18fps. This is possible, but uncommon. So you will have to use custom settings. Here is my suggested process:

  1. Create a custom video mode (Settings->Video Mode->Custome->Add…) Make sure the “Frames/sec” field is set to 18.

  2. Set the video mode to your new custom mode.

  3. Open the file you want to convert.

  4. In the Properties panel, set the speed to 0.6x.

  5. Encode the project - make sure the “Frames/sec” field is set to 18.000.

If you follow these steps, the resulting file will play back at the proper speed and there will be no duplicated frames.
