Final rendered video is in slow motion

[Damien Teng Y32171743968w]

everything plays normal in after effects, but when I export it out and view it on mp4 my video are in slow motion, but the time duration are the same. how do i fix this? i've tried different codec and the export resolution and the fps are the same as the composition.
