I have a clips captured with GoPro3+ with the frame rate 120fps. I would like to perform some slow motion clips by stretching the video on a time-line and then in the output I want to get the file with 30fps but smoothly slowed down.
All of the editors I tried are automatically converting the 120fps file into a 25-30fps when I import it to a program and all other frame just are lost.
Please suggest any video editing software under Linux which is fully supports 60fps and 120fps video files.
