which is ignored if using stream copy...
or was in my testing:-

ffmpeg -r 25 -i "FILE0307.mov"  -r 25  -vcodec copy  -acodec copy -y
"FILE0307-25-slow.mov"

turned:-

Stream #0.0(eng): Video: h264 (Main), yuv420p, 1920x1080p [PAR 1:1 DAR
16:9], 6051 kb/s, 29.97 fps

into:-

Stream #0.0(eng): Video: h264 (Main), yuv420p, 1920x1080p [PAR 1:1 DAR
16:9], 6051 kb/s, 30.03 fps
