[FFmpeg-user] Change frame rate without dropping/adding frames

I want to take a video at 60fps and convert it to 24fps, without adding or dropping frames. So the duration would be 2.5 times longer and the video would play in slow motion. I realize the setpts filter can do this, but I’d like to avoid re-encoding. This is possible in most NLE software, like Adobe Premiere or Apple Cinema Tools; is there a way to do it in ffmpeg? When I try setpts with “vcodec copy” I get the error “Filtering and streamcopy cannot be used together”.
